FIG. 1 is a block diagram showing an example of the configuration of a medical information processing system 1 according to the first embodiment. As shown in FIG. 1, the medical information processing system 1 includes a medical information display device 100 and an electronic medical record storage device 300.

As shown in FIG. 1, the medical information display device 100 is communicatively connected to an electronic medical chart storage device 300 via a network 200. The network 200 is, for example, a hospital LAN or the like. The medical information display device 100 and the electronic medical record storage device 300 are installed in a hospital or the like.

The electronic medical record storage device 300 is a device that stores medical care data relating to various medical treatments performed in a hospital or the like. For example, the electronic medical chart storage device 300 uses the data (vital data) such as pulse rate, heart rate, respiratory rate, blood pressure, body temperature, percutaneous arterial oxygen saturation (SpO2), and blood glucose level collected from a patient (subject). ) Is stored in association with time.

The vital data is information that numerically represents a condition related to a patient, and is an example of medical information in the present embodiment. Vital data is also called vital signs. In the present embodiment, examples of vital data include pulse rate, heart rate, respiratory rate, blood pressure, body temperature, percutaneous arterial oxygen saturation (SpO2), and blood glucose level. It is not limited to these. In addition, in the following description, a plurality of vital data refers to a plurality of types of vital data.

For example, the electronic medical record storage device 300 is installed as a part of an electronic medical record system introduced in a hospital or the like, and stores vital data generated by the electronic medical record system. For example, the electronic medical record storage device 300 is realized by a computer device such as a DB (Database) server and stores vital data in a semiconductor memory device such as a RAM (Random Access Memory) or a flash memory, or a storage circuit such as a hard disk or an optical disk. Let

The medical information display apparatus 100 acquires vital data from the electronic medical record storage apparatus 300 via the network 200, and performs various information processing using the acquired vital data. For example, the medical information display device 100 is realized by a computer device such as a workstation.

Specifically, the medical information display device 100 includes an I/F (interface) circuit 110, a storage circuit 120, an input circuit 130, a display 140, and a processing circuit 150.

The I/F circuit 110 is connected to the processing circuit 150 and controls transmission and communication of various data performed with the electronic medical chart storage device 300. For example, the I/F circuit 110 receives vital data from the electronic medical chart storage device 300 and outputs the received vital data to the processing circuit 150. For example, the I/F circuit 110 is realized by a network card, a network adapter, a NIC (Network Interface Controller), or the like.

The storage circuit 120 is connected to the processing circuit 150 and stores various data. For example, the storage circuit 120 stores the measurement results of a plurality of types of vital data received from the electronic medical chart storage device 300. Further, the storage circuit 120 stores the abnormal threshold value for each of the plurality of types of vital data.

The abnormal threshold value is a value that is an index of whether or not there is abnormality in the vital data, and is, for example, a value that indicates the upper limit or the lower limit of the normal range of each vital data. The abnormal threshold is different for each type of vital data. The storage circuit 120 also stores various programs. The storage circuit 120 is realized by a semiconductor memory device such as a RAM (Random Access Memory) or a flash memory, a hard disk, an optical disk, or the like. The storage circuit 120 is an example of a storage unit in this embodiment.

The input circuit 130 is connected to the processing circuit 150, converts an input operation received from the operator into an electric signal, and outputs the electric signal to the processing circuit 150. For example, the input circuit 130 is realized by a trackball, a switch button, a mouse, a keyboard, a touch panel, or the like.

The display 140 is connected to the processing circuit 150 and displays various data output from the processing circuit 150. For example, the display 140 is realized by a liquid crystal monitor, a CRT (Cathode Ray Tube) monitor, a touch panel, or the like. The input circuit 130 and the display 140 may be integrated. For example, the input circuit 130 and the display 140 are realized by a touch panel. The display 140 is an example of a screen in this embodiment.

The processing circuit 150 has a display control function 151, an acquisition function 152, a calculation function 153, and a detection function 154. The display control function 151 is an example of a display control unit. The acquisition function 152 is an example of an acquisition unit. The calculation function 153 is an example of a calculation unit. The detection function 154 is an example of a detection unit. For example, the processing circuit 150 is implemented by a processor.

Here, for example, the display control function 151, the acquisition function 152, the calculation function 153, and the detection function 154, which are the components of the processing circuit 150, are stored in the storage circuit 120 in the form of a program executable by a computer. ing. The processing circuit 150 realizes the function corresponding to each program by reading each program from the storage circuit 120 and executing each read program. In other words, the processing circuit 150 in the state where each program is read out has the functions shown in the processing circuit 150 of FIG. In FIG. 1, the single processing circuit 150 has been described as realizing each processing function of the display control function 151, the acquisition function 152, the calculation function 153, and the detection function 154, but a plurality of independent processing circuits are provided. The processing circuit 150 may be configured by combining the processors, and each processor may realize each processing function by executing each program.

The overall configuration of the medical information processing system 1 according to the first embodiment has been described above. With such a configuration, the medical information processing system 1 according to the first embodiment facilitates grasping the tendency of data such as vital data collected from a patient in time series. Specifically, the medical information processing system 1 dynamically calculates statistical information from vital data by the processing of the processing circuit 150 described in detail below, and displays the statistical information on the display 140 to grasp the data tendency. make it easier. Hereinafter, the processing of the medical information processing system 1 according to the first embodiment will be described in detail.

First, the electronic medical record storage device 300 stores vital data in association with time. That is, the electronic medical record storage device 300 stores the time-series medical information indicating changes over time of multiple types of vital data. The time-series medical information is information indicating changes over time in medical information that numerically represents a state related to a patient. More specifically, the time-series medical information is a measurement result of vital data. Here, the measurement result of the vital data is information in which the measured value of the vital data is associated with the measurement time or the input time of the vital data.

For example, the electronic medical record storage device 300 stores a measurement result of vital data measured for a patient and input by a doctor or a nurse who performed the measurement. As another example, the electronic medical record storage device 300 stores the measurement result of vital data acquired from a vital data measuring device (for example, a blood pressure monitor or a pulse monitor) via the network 200.

Here, an example of vital data stored in the electronic medical record storage device 300 will be described with reference to FIG.

FIG. 2 is a diagram illustrating an example of vital data according to the first embodiment. Note that, as an example, a case where the electronic medical chart storage device 300 stores vital data in association with measurement time will be described below.

For example, as shown in FIG. 2, the electronic medical record storage apparatus 300 stores each item of “patient ID”, “type”, “measurement date/time”, and “measurement value” in association with each other as vital data. Here, the "patient ID" is information for identifying the patient for whom the vital data has been measured. The "type" is the type of vital data (pulse, blood pressure, body temperature, respiratory rate, SpO2, blood sugar level, etc.). The “measurement date and time” is the date and time when the vital data was measured. The “measured value” is a numerical value measured as vital data. For example, as shown in FIG. 2, the electronic medical record storage device 300 stores, as vital data, a measured value “68” of the pulse of the patient P1, a measured value “141/89” of the blood pressure, and a measured value “36.5” of the body temperature. The measurement time is stored in association with "2017/06/07 09:15". Further, for example, the electronic medical record storage device 300 sets the measured value “59” of the pulse and the measured value “131/81” of the blood pressure of the patient P2 as the vital data at the measuring time “2017/06/14 14:45”. Correlate and store.

Next, details of the functions of the medical information display apparatus 100 will be described.

The acquisition function 152 acquires time-series medical information of multiple types of vital data from the electronic medical chart storage device 300 via the I/F circuit 110. The acquisition function 152 stores the acquired time-series medical information of vital data in the storage circuit 120.

Further, the acquisition function 152 acquires a patient ID for identifying a patient to be displayed, a type of vital data to be displayed, and a display period of vital data. The display period is a period of vital data displayed in time series. The display period is also referred to as a display target period.

For example, the acquisition function 152 receives the designation of the patient ID, the type of vital data to be displayed, and the display period of vital data input by an operator such as a doctor or a nurse via the input circuit 130. Get this information.

FIG. 3 is a diagram for explaining the display period according to the first embodiment. As an example, the acquisition function 152 acquires the start time “2017/4/27 00:00:00” and the end time “2017/5/8 00:00:00” as the display period, as shown in FIG. 3B. .. The acquisition function 152 sends the acquired display period to the calculation function 153 and the display control function 151.

The display period of the initial display may be set in advance. Further, the acquisition function 152 may acquire the display period from the display control function 151 that controls output to the display 140, or may acquire the display period from a video card or the like that performs display control on the display 140.

The calculation function 153 calculates statistical information from a plurality of vital data included in the display period acquired by the acquisition function 152. More specifically, the calculation function 153 calculates the median value (median), maximum value, and minimum value of each of the plurality of vital data.

FIG. 4 is a diagram illustrating an example of the statistical information according to the first embodiment. In the example shown in FIG. 4, it is assumed that the types of vital data to be displayed are pulse, blood pressure, and body temperature. The calculation function 153 retrieves the measurement results of the pulse, blood pressure, and body temperature during the display period from the storage circuit 120, and calculates the median value, minimum value, and maximum value of each of the plurality of vital data. The statistical information is not limited to these.

FIG. 5 is a diagram for explaining calculation of statistical information according to the first embodiment. In FIG. 5, as an example of vital data, vital data for the entire period measured for the pulse of the patient P1 is shown. As illustrated in FIG. 5, the calculation function 153 extracts the measurement result included in the display period from the measurement result of the pulse of the patient P1 stored in the storage circuit 120. For example, when the display period shown in FIG. 3 is acquired by the acquisition function 152, the calculation function 153 uses the vital data shown in FIG. 5 from “2017/4/27 00:00:00” to “2017/5 Acquire vital data measured by /8 00:00:00". The calculation function 153 calculates statistical information from the extracted vital data. The calculation function 153 sends the calculated statistical information to the display control function 151.

The display control function 151 aligns the display positions of the abnormal thresholds of the plurality of vital data, and displays the time-series medical information of the plurality of vital data in the same display area on the display 140. In this embodiment, the display format in which the display positions of the abnormal threshold values of the plurality of vital data are aligned and displayed is referred to as a first display format.

FIG. 6 is a diagram showing an example of a first display format of time-series display of vital data according to the first embodiment. As shown in FIG. 6, the display control function 151 displays the vital data in time series by displaying a line graph in which the vital data of the patient is plotted in association with the time axis on the display 140. The vertical axis of the graph shown in FIG. 6 is the value of each vital data, and the horizontal axis is the time. Each line graph shown in FIG. 6 shows time-series medical information of each vital data.

In the example shown in FIG. 6, the display control function 151 displays the measurement results of the pulse, blood pressure, and body temperature of the vital data stored in the storage circuit 120. Further, as shown in FIG. 6, a plurality of line graphs representing the measurement results of the plurality of vital data are displayed in the same display area. The display area of the graph shown in FIG. 6 is also called a timeline column. The type of vital data to be displayed and the patient ID to be displayed are assumed to be acquired by, for example, the acquisition function 152, but the display control function 151 may be configured to accept an operation on the screen by the operator. Further, the display control function 151 may change the type of vital data to be displayed when the detection function 154 described later detects a change in the type of vital data to be displayed in time series.

Further, in the example shown in FIG. 6, “from April 27 to May 8” is the display period. The display period may be the entire period in which the vital data of the patient to be displayed is measured, a preset period, or a period set by the operator. Furthermore, the display period can be arbitrarily changed by the operator.

The display control function 151 displays each abnormal threshold value of a plurality of vital data in association with the same scale on the axis of the graph. In this embodiment, the abnormal threshold having the larger value is called the upper limit value, and the abnormal threshold having the smaller value is called the lower limit value. Alternatively, an abnormal threshold value larger than the median value may be defined as an upper limit value, and an abnormal threshold value smaller than the median value may be defined as an upper limit value. The value between the lower limit and the upper limit is the normal range of each vital data. For example, in the example shown in FIG. 6, the upper limit value of the pulse is “100” and the lower limit value is “70”. The upper limit value of blood pressure is “140” and the lower limit value is “80”. Further, the upper limit value of the body temperature is “38” and the lower limit value thereof is “35”.

As shown in FIG. 6, the display control function 151 displays the pulse upper limit value “100”, the blood pressure upper limit value “140”, and the body temperature upper limit value “38” at the same position on the vertical axis of the graph. To do. Further, the display control function 151 displays the lower limit value of pulse “70”, the lower limit value of blood pressure “80”, and the lower limit value of body temperature “35” at the same position on the vertical axis of the graph.

Further, the display control function 151 aligns the display positions of the respective median values of the respective vital data calculated by the calculation function 153, and displays a plurality of time-series medical information on the display 140. Further, the display control function 151 aligns the display positions of the maximum value and the minimum value of each of the plurality of vital data, and displays the plurality of time-series medical information on the display 140. In the example shown in FIG. 6, the display control function 151 displays all of the abnormal threshold value, the median value, the maximum value, and the minimum value of each vital data together, but the display control function 151 uses the abnormal threshold value, the median value. Any one or two of the maximum value and the minimum value may be displayed together.

Here, the display control function 151 has a numerical value corresponding to one scale on the vertical axis for each of the plurality of vital data so that the display positions of the abnormal threshold value, the median value, the maximum value, and the minimum value of each vital data are aligned. Adjust. Therefore, the scale of each vital data is not unified, and the numerical value per scale is different for each of the plural vital data. For example, one scale in the direction in which the numerical value increases from the median shown in FIG. 6 corresponds to 10 for pulse, 20 for blood pressure, and 1 for body temperature.

Also, in each vital data, the numerical value corresponding to one scale is variable. For example, in blood pressure, "100" to "120" corresponds to 20 on one scale, while "140" to "160" corresponds to 2 on 20 scale.

In the example shown in FIG. 6, there are two types of abnormal thresholds, an upper limit value and a lower limit value, but there may be only one abnormal threshold value depending on the type of vital data to be displayed. Further, when there is vital data having only the upper limit value as the abnormal threshold value and vital data having only the lower limit value as the abnormal threshold value out of the plurality of vital data to be displayed, the display control function 151 sets the abnormal threshold value as the abnormal threshold value. The upper limit values are aligned for the plurality of vital data having only the upper limit value, and the upper limit values are aligned for the plurality of vital data having only the lower limit value as the abnormal threshold.

Alternatively, the display control function 151 determines whether the vital data having only the upper limit value as the abnormal threshold value and the vital data having only the lower limit value as the abnormal threshold value out of the plurality of vital data items to be displayed are displayed. Only the median values of a plurality of vital data may be aligned and displayed. Further, even when there are two kinds of abnormality thresholds, a plurality of abnormality thresholds indicating a gradual abnormality level may be used instead of the upper limit value and the lower limit value. In this case, each of the plurality of abnormality thresholds may be distinguished as the first abnormality threshold, the second abnormality threshold, or the like.

Although FIG. 6 shows a case where vital data is displayed in time series by a line graph, the embodiment is not limited to this. For example, the display control function 151 may perform time-series display using a box plot, etc., instead of the line graph. Further, the display control function 151 may display statistical information (histogram or the like) calculated from vital data included in the display period, in addition to the line graph, the box plot, and the like. For example, the display control function 151 may switch whether or not to display the histogram depending on whether or not the check box shown in the region R3 of FIG. 6 is checked.

Further, in FIG. 6, the display control function 151 displays the numerical value of each vital data “for each record”. However, in the case of a time series display such as a box plot, the display control function 151 collects the data for each fixed time unit. You may display the result. The time unit may be changed according to the operation by the operator. For example, the display control function 151, as shown in a region R5 of FIG. 6, includes a bar indicating a time unit such as “every record”, “half day”, “one day”, “two days”, and “one week”, and a bar. Slide to see the pointer and.

Further, the display control function 151 displays a plurality of types of vital data in a second display format different from the first display format shown in FIG. In the second display format, the scale of the axis of the graph is evenly distributed to each of the plurality of vital data regardless of the abnormal threshold value, the median value, the maximum value and the minimum value of each of the plurality of vital data. This is a display format for displaying a graph showing time-series changes of a plurality of vital data in increments.

FIG. 7 is a diagram showing an example of a second display format of time-series display of vital data according to the first embodiment. In the example shown in FIG. 7, the numerical value of the pulse is displayed in increments of 10 per scale on the vertical axis of the graph. In addition, the numerical value of blood pressure is displayed in 20 steps per scale on the vertical axis of the graph. Numerical values of body temperature are displayed in increments of 1 per scale on the vertical axis of the graph.

The display control function 151 switches between the first display format and the second display format according to the operation by the operator. For example, the display control function 151 changes the display format when the detection function 154 described later detects a change operation in which the operator operates the setting button shown in the region R10 of FIG. 6 to change the display format.

In addition, although the case where a plurality of types of vital data are displayed at the same time has been described with reference to FIGS. 6 and 7, the display control function 151 may display any one type of vital data in accordance with an operator's selection. Good.

The detection function 154 detects various operations on the screen by the operator. For example, the detection function 154 detects a display format change instruction by accepting a change operation for changing the display format by operating the setting button shown in the region R10 of FIG. 6 by the operator via the input circuit 130. .. In this case, the detection function 154 sends a display format change instruction to the display control function 151.

Further, the detection function 154 detects a time-unit change operation by accepting a slide operation of the pointer shown in the region R5 from the operator via the input circuit 130. Further, the detection function 154 detects whether or not the check box shown in the region R3 of FIG. 6 is checked. Further, the detection function 154 detects a change operation of the type of vital data to be displayed in time series when the operation of selecting the button shown in the region R1 of FIG. 6 is received from the operator. The detection function 154 sends various detected operations to the display control function 151. Note that the acquisition function 152 or the display control function 151 may receive the operation of the operator.

Next, an example of a procedure of processing by the medical information processing system 1 according to the first embodiment will be described with reference to FIG. FIG. 8 is a flowchart showing an example of the processing flow of the medical information processing system 1 according to the first embodiment. Before the processing of this flowchart is started, the acquisition function 152 acquires the measurement results of a plurality of vital data from the electronic medical chart storage device 300 via the I/F circuit 110 and saves them in the storage circuit 120. To do.

First, the acquisition function 152 acquires a patient ID that identifies a patient whose vital data is to be displayed, a type of vital data that is to be displayed, and a vital data display period (S1).

Next, the calculation function 153 calculates statistical information such as the median value, minimum value, and maximum value of each piece of vital data to be displayed during the display period (S2).

Then, the display control function 151, in the first display format described in FIG. 6, arranges the abnormal threshold value, the median value, the maximum value, and the minimum value of plural kinds of vital data to display plural kinds of numerical data. The series are displayed on the display 140 (S3).

Further, the detection function 154 determines whether or not an operation of changing the display period, the time unit, the type of vital data to be displayed, or the presence/absence of histogram display is detected (S4).

When the detection function 154 determines that any change operation has been detected (S4 “Yes”), it notifies the calculation function 153 and the display control function 151 of the detected change operation. Then, returning to the processing of S2, the calculation function 153 calculates the statistical information based on the changed display period, time unit, or the type of vital data to be displayed. Further, when the display of the histogram is set to “present”, the calculation function 153 calculates the number (frequency) of measurement values included in each data section of each vital data to be displayed.

Further, when the detection function 154 determines that the above-described change operation has not been detected (S4 “No”), the detection function 154 determines whether or not the display format change operation has been detected (S5).

When the detection function 154 determines that a display format change operation has been detected (S5 “Yes”), it sends a display format change instruction to the display control function 151. In this case, the display control function 151 displays the vital data in the second display format (S6).

When the detection function 154 determines that the operation of changing the display format has not been detected (S5 “No”), the screen display is not changed and the processing of this flowchart ends. In this flowchart, the first display format is the initial display as an example, but the second display format may be the initial display.

As described above, according to the medical information display apparatus 100 of the first embodiment, the display positions of the abnormal thresholds of the plurality of vital data are aligned, and the plurality of time-series medical information are displayed in the same display area on the display 140. Therefore, even when a plurality of vital data are displayed at the same time, a doctor or the like can easily discriminate abnormal vital data. Therefore, according to the medical information display device 100 of the first embodiment, a doctor or the like can quickly grasp the abnormal value from the displayed plurality of vital data.

With such a display format, it is possible to efficiently grasp a large amount of vital data in a shorter time than when a doctor refers to individual vital data individually. Further, with such a display format, when an abnormal value is measured with a plurality of vital data, the doctor can easily understand the mutual relationship.

Further, according to the medical information display apparatus 100 of the first embodiment, the median value of each of the plurality of vital data is calculated, and the display positions of the median values of each of the plurality of vital data are aligned so that the plurality of time-series medical data are displayed. Since the information is displayed on the display 140, it is possible to easily display the time-series changes of a plurality of vital data.

Further, according to the medical information display apparatus 100 of the first embodiment, the maximum value and the minimum value of each of the plurality of vital data are calculated, and the display positions of the maximum value and the minimum value of each of the plurality of vital data are aligned. Since a plurality of time-series medical information is displayed on the display 140, the time-series changes of a plurality of vital data can be displayed more easily.

Further, the abnormality thresholds of the plurality of vital data of the first embodiment are different values, and the medical information display device 100 of the first embodiment displays a graph showing changes in time series of the plurality of vital data. Then, each abnormal threshold value of the plurality of vital data is displayed in association with the same scale on the axis of the graph. Therefore, according to the medical information display apparatus 100 of the first embodiment, it is possible to display the presence/absence of abnormality of a plurality of vital data at each time in one graph.

Further, according to the medical information display apparatus 100 of the first embodiment, the first display format and the second display format are switched according to the operation of the doctor or the like who is the operator, so that the medical information display device 100 can be used for the doctor or the like. It is possible to provide a graph showing a time series change of a plurality of vital data in a suitable display format.

In the present embodiment, the abnormal threshold value of each of the plurality of vital data is stored in the storage circuit 120 in advance, but the calculation function 153 of the medical information display device 100 causes the abnormal threshold value of each of the plurality of vital data to be stored. The abnormal threshold value may be calculated by analysis processing. When the configuration is adopted, according to the medical information display apparatus 100, it is possible to judge an abnormal numerical value from the recorded vital data and present it to a doctor or the like without registering the abnormal threshold value in advance. Further, the calculation function 153 of the medical information display device 100 may calculate the abnormal threshold value of each of the plurality of types of numerical data according to a predetermined rule.

In the present embodiment, the measurement result of vital data is stored in the storage circuit 120 of the medical information display device 100, but the acquisition function 152 of the medical information display device 100 displays the time series of vital data. When it is started, the measurement result of vital data may be acquired from the electronic medical chart storage device 300. Further, the display control function 151 may directly display the measurement result of the vital data stored in the electronic medical chart storage device 300 and display it on the display 140. Although the storage circuit 120 is an example of a storage unit in the present embodiment, the electronic medical chart storage device 300 may be an example of a storage unit.

(Second embodiment)
In the above-described first embodiment, the display format of time-series display of a plurality of types of vital data has been described. On the other hand, in the second embodiment, a display format for displaying vital data and other information in association with each other will be described.

The medical information processing system 1 according to the second embodiment has the same configuration as the first embodiment shown in FIG. Further, the medical information display apparatus 100 according to the second embodiment includes an I/F circuit 110, a memory circuit 120, an input circuit 130, a display 140, and a processing circuit 150, as in the first embodiment. Have. The I/F circuit 110, the memory circuit 120, the input circuit 130, and the display 140 of the second embodiment have the same functions as those of the first embodiment.

Further, the storage circuit 120 of the second embodiment stores, in addition to the same information as that of the first embodiment, record information indicating the condition of the patient in association with time. In the present embodiment, the record information is information different from the vital data, and is, for example, a meal record, a sleep record, a nursing record, a medication record of the patient, but may include other information. .. The meal record is a record of the time when the patient took a meal and the menu of the meal taken by the patient. The sleep record is a record of the sleep time of the patient and is measured by an activity meter or the like. The nursing record is information related to a patient's condition recorded by a nurse or the like, and is information in which a recording time and a sentence explaining the patient's condition are associated with each other. The medication record is information in which the type, amount, and administration time of the drug administered to the patient are associated with each other.

Moreover, the processing circuit 150 has a display control function 151, an acquisition function 152, a calculation function 153, and a detection function 154, as in the first embodiment.

The acquisition function 152 has the same function as that of the first embodiment, and receives various record information from the electronic medical record storage device 300 via the I/F circuit 110 and stores the record information in the storage circuit 120. Further, the acquisition function 152 may receive various kinds of record information from an external device other than the electronic medical record storage device 300.

The display control function 151 has the same function as that of the first embodiment, and displays the record information in association with the vital data.

FIG. 9 is a diagram showing an example of display of vital data according to the second embodiment. As shown in FIG. 9, the display control function 151 has the record information associated with the vital data in the vicinity of the marker (the circular marker in the example shown in FIG. 9) indicating the numerical value of the vital data on the graph. An icon 90 indicating that the operation is performed is displayed. The display control function 151 displays the record information associated with the vital data when the detection function 154 described later detects that the icon 90 is operated by the operator.

In the example shown in FIG. 9, since the blood glucose level measurement result measured on May 4 is associated with the meal record of the patient, the display control function 151 displays the meal record on the screen.

The association between the record information and the vital data may be defined in advance and registered in the storage circuit 120, or may be determined according to time. For example, the display control function 151 associates a meal record, a sleep record, a nursing record, a medication record, or the like associated with a past time within a predetermined time from the measurement time of the vital data or the input time with the vital data. It may be determined that the record information is to be recorded and displayed on the screen. The association between the vital data and the record information may be determined by different criteria depending on the type of vital data or the type of information indicating the patient's condition.

Further, the display control function 151 does not display the icon 90, and when the detection function 154 described later detects that the operator operates the marker indicating the numerical value of the vital data, the display control function 151 displays Information indicating the patient's condition associated with the vital data may be displayed. The display mode of the icon 90 is not limited to the example shown in FIG.

Further, the display control function 151 may associate the icons 90 with the numerical values of all vital data, but only the numerical values exceeding the abnormal threshold value or the numerical values identified as outliers by the data analysis by the calculation function 153. , 90 may be displayed in association with each other.

Further, in the example shown in FIG. 9, the display control function 151 displays only one type of vital data, but it displays a plurality of vital data and associates each of the plurality of vital data with the record information. It may be displayed. In this case, the display control function 151 may display different recording information for each of the plurality of vital data, or may display the same recording information for each of the plurality of vital data regardless of the type of vital data. It may be displayed.

Further, in the example shown in FIG. 9, since the check box of the region R3 is checked, the display control function 151 displays a histogram showing the number (frequency) of measured values in the region R2.

The detection function 154 has the same function as that of the first embodiment, and detects that the operator has operated the icon 90 or the marker indicating the numerical value of vital data via the input circuit 130. When the detection function 154 detects that the operator has operated the icon 90 or the marker indicating the numerical value of the vital data, the detection function 154 notifies the display control function 151 of the operated icon 90 or the numerical value of the vital data. The operator's operation is, for example, an operation of clicking a mouse or the like, but is not limited to this.

The calculation function 153 has the same function as that of the first embodiment and further calculates various statistical information.

FIG. 10 is a diagram for explaining calculation of statistical information according to the second embodiment. As shown in FIG. 10, the calculation function 153 uses, as statistical information, the mean value, the standard error, the standard deviation, the variance, the kurtosis, and the distortion in addition to the median value, the minimum value, and the maximum value of the vital data included in the display period. Calculate degrees, ranges, totals, or sample sizes. Then, the display control function 151 may display the statistical information calculated by the calculation function 153 on the display 140. The statistical information is not limited to these examples, and the calculation function 153 may calculate more types of statistical information indicating the tendency of vital data.

In addition, FIG. 11 is a diagram illustrating an example of histogram data according to the second embodiment. The calculation function 153 calculates the histogram data shown in FIG. 11 as statistical information from the vital data described in FIG. As an example, the calculation function 153 uses data about the measured value of the pulse measured from “2017/4/27 00:00:00” to “2017/5/8 00:00:00” which is the display period. Sections "~50", "~55", "~60", "~65", "~70" and "~75" are provided, and the number of measurement values included in each data section is calculated. Although the pulse is taken as an example in FIG. 11, the calculation function 153 also calculates histogram data for other types of vital data in the same manner. The data section may be different depending on the value of the measured value or the type of vital data. The calculation function 153 sends the calculated histogram data or statistical information to the display control function 151.

Further, in FIG. 9, the histogram generated from the histogram data calculated by the calculation function 153 is displayed, but the display control function 151 may display other statistical information according to the operation of the operator. Good. Further, the display format of the histogram is not limited to the example shown in FIG.

FIG. 12 is a diagram showing an example of display of statistical information according to the second embodiment. As shown in FIG. 12, the display control function 151 displays the histogram in the region R2 and the skewness and kurtosis in the region R4.

Further, when the acquisition function 152 acquires a plurality of display periods, the display control function 151 may display the histogram generated for each of the plurality of display periods. Here, the case where the acquisition function 152 acquires a plurality of display periods is, for example, a case where the display period is changed by the operation of the operator and the acquisition function 152 acquires the display periods before and after the change.

To give an example, first, the operator performs an operation of changing the display period of the time series display. That is, the operator who referred to the vital data displayed in time series shortens the display period for observing a partially enlarged image, extends the display period for observing a longer period, or The display period is scrolled to observe the time. Here, examples of the operation of changing the display period include an operation of a mouse, a tablet, or the like included in the input circuit 130.

Specifically, the operator scrolls the display period by operating the wheel of the mouse. Further, for example, the operator extends the display period or shortens the display period by operating the wheel of the mouse while pressing a predetermined key of the keyboard. Further, for example, the operator scrolls the display period by swiping the tablet. Further, for example, the operator extends or shortens the display period by pinching in/pinching out the tablet.

Next, the display control function 151 changes the display period in time series display of vital data. Further, the detection function 154 detects a change operation of the display period, and the acquisition function 152 acquires the changed display period. For example, when the operator scrolls the display period, the acquisition function 152 continuously acquires the continuously changed display period. Here, the calculation function 153 calculates histogram data from the vital data included in the display period each time the display period is acquired. Then, the display control function 151 generates and displays a histogram every time the histogram data is calculated. For example, the display control function 151 replaces the newly generated histogram with the already displayed histogram and displays it, or displays it side by side.

Further, for example, the display control function 151 may display the histograms generated for each display period by superimposing them on each other.

FIG. 13 is a diagram showing another example of display of statistical information according to the second embodiment. The display control function 151 superimposes and displays the newly generated histogram and the histogram generated a fixed time ago (for example, 5 seconds ago), as shown in a region R2 of FIG.

Here, when displaying a plurality of histograms in a superimposed manner, the display control function 151 may simply display the histograms with polygonal lines or curves as shown in the region R2 of FIG. Further, the display control function 151 may display the histograms generated in the past so that the transparency is higher than that of the newly generated histogram, as shown in a region R2 of FIG. Here, the transparency of the histogram is a parameter that affects the visibility of the histogram. For example, the transparency of the histogram may be the thickness of the line indicating the histogram, the interval between the broken line and the dotted line indicating the histogram, in addition to the degree of see-through.

Further, for example, the display control function 151 displays the histograms generated for each display period side by side. As an example, the display control function 151 displays a newly generated histogram, a histogram generated 5 seconds ago, a histogram generated 10 seconds ago, and a histogram generated 15 seconds ago side by side.

When displaying a plurality of histograms, the display control function 151 may display the histograms after normalizing according to the number of vital data used to generate each histogram. For example, in FIG. 13, when the number of vital data used to generate the histogram of the solid line is “20” and the number of vital data used to generate the histogram of the broken line is “10”, the display control function 151 doubles the height of the broken line histogram and displays it in the region R2. In other words, the display control function 151 may display the histogram at a ratio according to the number of vital data included in each period.

Further, the display control function 151 may display the difference between the histograms generated for each of the plurality of display periods. For example, in FIG. 13, the calculation function 153 indicates the number of measurement values (frequency) for each data section between the vital data used for generating the solid line histogram and the vital data used for generating the broken line histogram. Calculate the difference. Then, the display control function 151 displays the calculated difference in a histogram as the difference between the histograms. The display control function 151 may display the difference by superimposing it on the solid line histogram and the broken line histogram shown in FIG. 13, or may display the difference instead of the solid line histogram and the broken line histogram.

Further, the display control function 151 may display the result of the test of the difference between the histograms generated for each of the plurality of display periods. For example, in FIG. 13, the calculation function 153 uses the vital data used to generate the histogram of the solid line and the vital data used to generate the histogram of the broken line to test the difference by setting the significance probability P to “0.15”. And display the results of the test.

Here, the calculation function 153 may calculate the statistical information of the vital data included in the display period with the display period as a unit, or may be calculated for each divided time obtained by dividing the display period into time units. .. For example, when "April 27th to May 8th" is the display period, the calculation function 153 may calculate statistical information about vital data from April 27th to May 8th, The statistical information may be calculated for each divided time such as “1 day” or “1 week”.

To give an example, the calculation function 153 divides the display period into “1 days”, and uses the minimum value, the first quartile, the median, and the third quartile as statistical information of vital data on each day. Calculate points and maximums. Then, the display control function 151 time-sequentially displays the statistical information of each day as a box and whisker chart.

FIG. 14 is a diagram showing an example of a box-and-whisker diagram display according to the second embodiment. Specifically, the display control function 151 displays a whisker indicating a minimum value to a maximum value, a box indicating a first quartile to a third quartile, and a median value. A box and whisker chart consisting of the boxes shown is generated for each day of the display period and displayed in association with the time axis.

In FIG. 14, a box and whisker plot based on the statistical information calculated for each “one day” is shown, but the time unit for calculating the statistical information is arbitrary. The time unit may be changed according to the operation by the operator. For example, the display control function 151, as shown in a region R5 of FIG. 14, includes a bar indicating a time unit such as “every record”, “half day”, “one day”, “two days”, and “one week”, and a bar. Slide to see the pointer and. Next, the detection function 154 detects a time-unit change operation by receiving a pointer slide operation from the operator via the input circuit 130.

Here, except when the time unit is changed to “every record”, the calculation function 153 divides the display period into each changed time unit and calculates the statistical information for each divided time. Then, the display control function 151 time-sequentially displays the box-and-whisker chart for each changed time unit as the statistical information for each divided time. On the other hand, when the time unit is changed to "every recording", the display control function 151 performs time-series display with a line graph.

The calculation function 153 may calculate the time unit for calculating the statistical information according to the display period. For example, the calculation function 153 calculates the time unit such that the number of box-and-whisker diagrams displayed is a predetermined number (for example, “10 to 15”). That is, the calculation function 153 calculates the time unit according to the display granularity. As an example, when the display period is "April 27th to May 8th" and the time unit is "half day", the box plot is "22" and the time unit is "1 day". Then, the box-and-whisker chart becomes "11", and the box-and-whisker chart becomes "6" when the time unit is "2 days". Therefore, when the display period is “April 27th to May 8th”, the calculation function 153 calculates “1st day” as a time unit and calculates statistical information for each “1st day”.

In addition, in FIG. 14, a box-and-whisker chart is shown as an example of the time-series display of the statistical information calculated for each divided time, but the embodiment is not limited to this. For example, the display control function 151 time-sequentially displays the statistical information for each divided time by a figure showing a mean value and an error bar (a bar having a length corresponding to the standard deviation), a candle chart, a line graph, or the like. Good.

Further, the divided periods may overlap each other. Here, an example in which the display period is “August 3 to August 6”, the time unit is “1 day”, and the “kurtosis” is calculated as the statistical information for the overlapping segment periods As described below. First, the display control function 151 displays the vital data of “August 3 to August 6” in time series, and the acquisition function 152 acquires “August 3 to August 6” as the display period. ..

Next, the calculation function 153 acquires the segment times that overlap each other. For example, the calculation function 153 divides the display period into “1 days” and obtains the time including each day and the days before and after the display period as the overlapping time. That is, the calculation function 153 uses the “August 2 to August 4”, “August 3 to August 5”, “August 4 to August 6”, and “August 5 to 8”. Four division times of "7th of a month" are acquired.

Next, the calculation function 153 calculates the “kurtosis” for each segment time from the vital data included in the segment time. Then, the display control function 151 displays the “kurtosis” for each divided time in time series. For example, the display control function 151 plots the kurtosis calculated for “August 2 to August 4” at the position of “August 3” and for “August 3 to August 5”. The calculated kurtosis is plotted at the position of "August 4", and the kurtosis calculated for "August 4 to August 6" is plotted at the position of "August 5", and "8 The kurtosis calculated for "5th to 7th of August" is plotted at the position of "8th August" to display the "kurtosis" for each segmented time series.

Next, an example of a procedure of processing by the medical information processing system 1 according to the second embodiment will be described with reference to FIG. FIG. 15 is a flowchart showing an example of the processing flow of the medical information processing system 1 according to the second embodiment.

The process from the acquisition process of the patient ID, the type of vital data to be displayed, and the display period in S101 to the process of time-sequentially displaying the vital data in S106 in the second display format according to the first embodiment described in FIG. This is the same as the processing of S1 to S6.

The detection function 154 of the present embodiment has the same function as that of the first embodiment, and detects that the operator has operated the icon 90 or the marker indicating the numerical value of vital data via the input circuit 130. It is determined whether or not (S107).

When the detection function 154 determines that the operator has operated the icon 90 or the marker indicating the numerical value of the vital data (S107 “Yes”), it controls the display of the operated numerical value of the icon 90 or the vital data. Notify the function 151. In this case, the display control function 151 displays information indicating the state of the patient corresponding to the operated icon 90 or the numerical value of the vital data (S108). The information indicating the state of the patient corresponding to the operated icon 90 or the numerical value of the vital data is information indicating the state of the patient at the measurement time or the input time of the vital data, as described with reference to FIG. 9.

If the detection function 154 determines that the operator has not operated the icon 90 or the marker indicating the numerical value of the vital data (S107 “No”), the screen display is not changed and the flowchart of FIG. The process ends.

As described above, according to the medical information display apparatus 100 of the second embodiment, in addition to the effects of the first embodiment, the record information indicating the condition of the patient is displayed in association with the vital data. Etc., the recorded information at the measurement time or input time of vital data can be easily confirmed on the screen.

For example, conventionally, when an abnormal value of vital data is measured, in order to know the state of the patient at the time of measuring the vital data, a nursing record or meal record at that time is separately searched and referred to. It may have required work. In such a case, it may take time for a doctor or the like to examine the information, and it may be difficult to make a quick decision.

On the other hand, according to the medical information display apparatus 100 of the second embodiment, a doctor or the like can easily confirm the value of vital data and the recorded information at the measurement time or input time of the vital data. Therefore, it is possible to assist the doctor in making a quick decision during the medical examination.

(Third Embodiment)
In the third embodiment, a case will be described in which a designated period designated from the display periods is acquired as a period for calculating statistical information regarding vital data displayed in time series.

The medical information processing system 1 according to the third embodiment has the same configuration as the medical information processing system 1 shown in FIG. 1, and is processed by the display control function 151, the acquisition function 152, the calculation function 153, and the detection function 154. Are partly different. Therefore, the same components as those described in the first embodiment are designated by the same reference numerals as those in FIG. 1, and the description thereof will be omitted.

First, the display control function 151 displays vital data in time series. For example, as shown in FIG. 16, the display control function 151 causes the display 140 to display a line graph in which the measured pulse values of the patient P1 are plotted in association with the time axis, thereby displaying the vital data in time series. .. Here, FIG. 16 is a diagram for explaining the designated period according to the third embodiment.

Note that FIG. 16 illustrates a case where vital data is displayed in time series by a line graph, but the embodiment is not limited to this. For example, the display control function 151 may be a case where time-series display such as a box plot is performed instead of the line graph. Further, the display control function 151 may display the statistical information (histogram or the like) calculated from the vital data included in the display period, in addition to the line graph, the box-and-whisker chart and the like.

Next, the detection function 154 detects the operation of designating the designated period from the display period. For example, the detection function 154 detects the operation of designating the designated period shown in FIG. 16 through the operation of the mouse, the tablet, or the like included in the input circuit 130. Then, the acquisition function 152 acquires the designated period based on the operation detected by the detection function 154.

The designated period will be described below with reference to FIGS. 17, 18 and 19. 17, 18 and 19 are diagrams for explaining the designated period according to the third embodiment. Note that FIG. 17 is an enlarged view of a part of the time-series display shown in FIG. 16, in which the X-axis shows time and the Y-axis shows measured pulse values.

First, the operator performs an operation of specifying two points in the coordinate system of FIG. 17 via the input circuit 130. For example, the operator operates the mouse included in the input circuit 130 to start dragging at the position of coordinates (1.874, 3.001) and drop at the position of coordinates (5.223, 2.998) in FIG. In this case, the detection function 154 detects that the drag start operation at the coordinate (1.874, 3.001) and the drop operation at the coordinate (5.223, 2.998) have been performed.

Next, as shown in FIG. 18, the acquisition function 152 acquires the X-axis (time axis) coordinate and the operation content from the operation detected by the detection function 154. Then, as shown in FIG. 19, the acquisition function 152 acquires the designated period by converting the X-axis (time axis) coordinates into time and converting the operation content into the display meaning. For example, as illustrated in FIG. 19, the acquisition function 152 acquires the start time “2017/4/28 06:24:15” and the end time “2017/5/1 22:15:33” as the designated period.

Then, the calculation function 153 calculates the statistical information from the vital data included in the designated period, and the display control function 151 displays the calculated statistical information. For example, the calculation function 153 calculates histogram data as statistical information from the vital data included in the specified period, and the display control function 151 uses the histogram data, a histogram based on the histogram data, and a statistical amount (distortion or freshness) related to the histogram. Etc.) is displayed.

Further, when the acquisition function 152 acquires a plurality of designated periods, the display control function 151 may display the histogram generated for each of the plurality of designated periods. Here, the case where the acquisition function 152 acquires a plurality of designated periods is, for example, a case where a plurality of designated periods are designated by the operation of the operator.

For example, the display control function 151 replaces the newly generated histogram with the already displayed histogram and displays it. Further, for example, the display control function 151 superimposes and displays the histograms generated for each designated period. Here, when displaying a plurality of histograms in a superimposed manner, the display control function 151 may display the histograms in a simplified manner by using polygonal lines or curves, or may increase the transparency of histograms generated in the past. It may be displayed.

Further, for example, the display control function 151 displays the histograms generated for each designated period side by side. As an example, as illustrated in FIG. 20, when the acquisition function 152 acquires the period T1, the period T2, and the period T3 as the designated period, the display control function 151 determines that the period T1, the period T2, and the period T3 are the same. The generated histogram is displayed in each of the regions R6, R7, and R8. 20. FIG. 20 is a diagram showing an example of display of statistical information according to the third embodiment.

Further, for example, the calculation function 153 calculates a statistical amount as statistical information from the vital data included in the designated period, and the display control function 151 displays the statistical amount. Further, for example, the calculation function 153 calculates the statistical information for each divided time obtained by dividing the designated period into time units, and the display control function 151 displays the statistical information for each divided time in time series by a box plot or the like. ..

As an example, when the vital data is displayed in time series by a line graph in which the time unit is “every record”, the calculation function 153 divides the specified period into “one day” and the vital data of each day. As the statistical information of the data, the minimum value, the first quartile, the median, the third quartile, and the maximum value are calculated. Then, the display control function 151 displays the statistical information of each day as a box-and-whisker chart in time series for the designated period of the display period, and sets the time unit as “every record” for the period other than the designated period of the display period. Vital data is displayed in time series by a line graph.

As another example, when the vital data is displayed in time series by a box-and-whisker chart in which the time unit is “one day”, the calculation function 153 uses the minimum value as the statistical information of the vital data within the designated period. , The first quartile, the median, the third quartile, and the maximum. Then, the display control function 151 displays one box-and-whisker chart for the designated period, and displays the box-and-whisker chart with the time unit of “1 day” for the periods other than the designated period in the display period in time series.

Next, an example of a processing procedure by the medical information processing system 1 will be described with reference to FIG. FIG. 21 is a flow chart for explaining a series of processing flows of the medical information processing system 1 according to the third embodiment. Steps S201, S204, and S209 are steps corresponding to the display control function 151. Also, steps S202 and S207 are steps corresponding to the acquisition function 152. Further, steps S203 and S208 are steps corresponding to the calculation function 153. Further, steps S205 and S206 are steps corresponding to the detection function 154.

First, the processing circuit 150 reads the vital data from the storage circuit 120 and displays the vital data in time series (step S201). Next, the processing circuit 150 acquires the display period of the vital data displayed in time series (step S202), and calculates statistical information from the vital data included in the display period (step S203). Next, the processing circuit 150 displays the calculated statistical information on the display 140 by a histogram, a box plot, etc. (step S204).

Here, the processing circuit 150 determines whether or not a change operation of the display period is detected (step S205). When the change operation is detected (Yes at Step S205), the processing circuit 150 moves to Step S202 again. On the other hand, when the change operation has not been detected (No at Step S205), the processing circuit 150 determines whether or not the specified operation for the specified period has been detected (Step S206).

When the designation operation is detected (Yes at Step S206), the processing circuit 150 acquires the designation period (Step S207) and calculates statistical information from vital data included in the designation period (Step S208). Next, the processing circuit 150 displays the calculated statistical information on the display 140 by a histogram, a box plot, etc. (step S209), and shifts to step S205 again. On the other hand, when the designated operation is not detected (No at Step S206), the processing circuit 150 ends the processing.

As described above, according to the third embodiment, the detection function 154 detects the operation of designating the designated period from the display period of the vital data displayed in time series. Further, the acquisition function 152 acquires the designated period. Further, the calculation function 153 calculates statistical information from the vital data included in the designated period. Further, the display control function 151 displays the calculated statistical information. Therefore, the medical information processing system 1 according to the third embodiment can easily understand the data tendency by displaying the statistical information in the desired range of the operator among the displayed vital data. it can.

The detection function 154 may detect the drag operation and the drop operation illustrated in FIG. 17 as the display period changing operation. In this case, the acquisition function 152 acquires the X-axis (time axis) coordinate and the operation content from the operation detected by the detection function 154, as illustrated in FIG. 18. Also, as shown in FIG. 19, the acquisition function 152 uses the start time “2017/4/28 06:24:15” and the end time “2017/5/1 22:15:33” as the display period after the change. To get. Next, the calculation function 153 calculates statistical information from the vital data included in the changed display period, and the display control function 151 displays a histogram, a box plot, etc. as the statistical information.

(Fourth Embodiment)
In the fourth embodiment, variations of displaying statistical information will be described. The medical information processing system 1 according to the fourth embodiment has the same configuration as that of the medical information processing system 1 shown in FIG. 1, and a part of the processing by the display control function 151 and the calculation function 153 is different. Therefore, the same components as those described in the first embodiment are designated by the same reference numerals as those in FIG. 1, and the description thereof will be omitted.

Hereinafter, a display example of the statistical information according to the fourth embodiment will be described with reference to FIGS. 22A and 22B. 22A and 22B are diagrams showing an example of display of statistical information according to the fourth embodiment.

First, the calculation function 153 calculates histogram data from the vital data included in the display period. Next, the display control function 151 displays a histogram based on the histogram data, as shown in the area R2 of FIG. 22A. Further, the display control function 151 displays the threshold value as shown in the area R2 of FIG. 22A.

Here, the threshold indicates whether or not the value of vital data is in a normal range. For example, in the case of FIG. 22A, with “101” and “79” as the threshold values, the ratio of the measured values of the pulse within the display period being “101” or more is “4.0%”, It indicates that the ratio of the measured value being "79" or less is "3.0%". That is, the display control function 151 can present how normal the vital data is by displaying the threshold value.

The threshold may be calculated by the calculation function 153 based on vital data. For example, the calculation function 153 calculates the standard deviation of the measured values of the pulse measured for the patient P1 for the entire period, the measured value for the display period, the measured value for the designated period, and the like, (+2σ)” and “79(−2σ)” are used as threshold values for calculation. Then, as shown in FIG. 22B, the display control function 151 displays “101 (+2σ)” and “79 (−2σ)” as threshold values. Further, in the display control function 151, the ratio of the measured values within the display period exceeding “101(+2σ)” is “3.0%”, and the ratio falling below “79(−2σ)” is “ 0.0%” is displayed. By displaying the threshold value calculated based on the vital data, the display control function 151 can dynamically present how normal the vital data is within the normal range.

Further, when the vital data includes an abnormal value due to a measurement or input error, the display control function 151 can notify the operator that the abnormal value is included. For example, the calculation function 153 calculates the standard deviation of the measured pulse values measured for the patient P1, and uses the pulse rate of “+3σ” and the pulse rate of “−3σ” as thresholds. Then, the display control function 151 can present the measurement value, which does not fall within the range of “±3σ”, to the operator as an abnormal value due to an error in measurement or input.

22A and 22B show the case where the threshold value is displayed on the histogram as a method of displaying the comparison result of the vital data and the threshold value, but the embodiment is not limited to this. For example, the display control function 151 may display the threshold value on the left side (vertical axis) of the graphs shown in FIGS. 22A and 22B or on the graph. Further, for example, the display control function 151 may numerically display the threshold value. Further, for example, the display control function 151 may display whether or not the vital data includes a value that exceeds the threshold value or a value that falls below the threshold value. Further, for example, the display control function 151 may display the ratio and number of vital data that exceeds the threshold value and vital data that falls below the threshold value.

Next, another display example of the statistical information according to the fourth embodiment will be described with reference to FIG. FIG. 23 is a diagram showing an example of display of statistical information according to the fourth embodiment.

First, the calculation function 153 calculates a statistic each time a display period or a designated period is acquired. For example, when the display period is continuously scrolled by the operator, the acquisition function 152 continuously acquires the continuously changed display period, and the calculation function 153 calculates the statistic amount for each display period. calculate. Hereinafter, as an example, a case where the kurtosis is calculated for each display period will be described.

Then, the display control function 151 displays the history of the calculated kurtosis, as shown in FIG. That is, the display control function 151 updates the graph each time the kurtosis is calculated, and displays the entire graph while scrolling to the left so that the right end of the display range is the current time. The display control function 151 may display the graph shown in FIG. 23 together with a time series display of vital data such as a line graph or a box and whisker graph, or a histogram.

Here, when the display period is continuously scrolled and the kurtosis is unstable and fluctuates in the history display of FIG. 23, the operator determines that the state of the patient P1 is not stable. be able to. In addition, when the kurtosis suddenly increases while the display period is continuously scrolled, the operator includes an abnormal value due to an error in measurement or input in the new display range. Can be determined.

Next, another display example of the statistical information according to the fourth embodiment will be described with reference to FIG. FIG. 24 is a diagram showing an example of display of statistical information according to the fourth embodiment.

First, the calculation function 153 acquires a plurality of types of vital data. For example, the calculation function 153 acquires a plurality of types of vital data by receiving a designation operation of a type of vital data from the operator via the input circuit 130. As an example, the calculation function 153 acquires a plurality of types of vital data by receiving the selection of the button shown in the region R1 of FIG. Further, for example, when a plurality of types of vital data are displayed in time series, the calculation function 153 acquires the type of vital data displayed in time series. Hereinafter, a case where the calculation function 153 acquires “pulse” and “blood pressure” as the types of vital data will be described.

Next, the calculation function 153 calculates a value indicating the correlation between “pulse” and “blood pressure”. For example, the calculation function 153 calculates a correlation coefficient ρ between “pulse” and “blood pressure” included in the display period or the designated period. Further, for example, the calculation function 153 calculates the correlation coefficient ρ between the “pulse” and the “blood pressure” for each divided time obtained by dividing the display period or the designated period for each time unit.

Then, the display control function 151 displays the correlation coefficient ρ. For example, as shown in FIG. 24, the display control function 151 displays the correlation coefficient ρ calculated for each divided time in a graph in association with the time axis. Here, as shown in FIG. 24, the display control function 151 may also display a graph showing the correlation coefficient ρ in a time series display of vital data such as a line graph or a box plot, or together with a histogram. Good.

(Fifth Embodiment)
Now, the first to fourth embodiments have been described so far, but the embodiments may be implemented in various different forms other than the above-described embodiments.

Although the vital data has been described in the above-described embodiment, the embodiment is not limited to this, and can be applied to various numerical data indicating medical information. Here, examples of the medical information include, in addition to vital data, inspection data of a sample (blood or the like), measurement data of images collected from a patient (blood vessel diameter, blood flow volume, etc.), and the like.

For example, the medical information processing system 1 includes a sample test server that stores test data of a sample instead of the electronic medical record storage device 300 or in addition to the electronic medical record storage device 300. In this case, the I/F circuit 110 receives the test data from the sample test server and outputs the received test data to the processing circuit 150. The sample inspection server is an example of a storage unit.

Further, for example, the medical information processing system 1 includes a PACS (Picture Archiving Communication System) server instead of the electronic medical chart storage device 300 or in addition to the electronic medical chart storage device 300. In this case, the I/F circuit 110 receives the measurement data of the image from the PACS server and outputs the received measurement data to the processing circuit 150. The PACS server is an example of a storage unit.

Further, although the example of FIG. 1 has been shown as the configuration of the medical information processing system 1 so far, the embodiment is not limited to this. For example, as shown in FIG. 25, the medical information processing system 1 may include a terminal device 400 in addition to the medical information display device 100 and the electronic medical record storage device 300. 25 is a block diagram showing an example of the configuration of the medical information processing system 1 according to the fifth embodiment. As shown in FIG. 25, the medical information display device 100, the electronic medical record storage device 300, and the terminal device 400 are communicably connected via a network 200. Here, the terminal device 400 is, for example, a tablet, a personal computer, or the like.

The terminal device 400 includes an input circuit 410 and a display 420, which are not shown. The input circuit 410 converts the input operation received from the operator into an electric signal and outputs the electric signal to the medical information display device 100. For example, the input circuit 410 is realized by a trackball, a switch button, a mouse, a keyboard, a touch panel, or the like.

The display 420 displays various data output from the medical information display device 100. For example, the display 420 is realized by a liquid crystal monitor, a CRT (Cathode Ray Tube) monitor, a touch panel, or the like. The input circuit 410 and the display 420 may be integrated. For example, the input circuit 410 and the display 420 are realized by a touch panel.

For example, the display control function 151 receives a time-series display instruction from the operator via the input circuit 410 and displays the numerical data indicating the medical information in time series. Next, the acquisition function 152 acquires the display period and the designated period, and the calculation function 153 calculates statistical information from the numerical data included in the display period and the designated period. Then, the display control function 151 causes the display 420 to display a histogram or a boxplot as statistical information. When the medical information processing system 1 includes the terminal device 400, the medical information display device 100 may not include the input circuit 130 and the display 140. Further, the medical information processing system 1 may include a plurality of terminal devices 400.

According to the configuration shown in FIG. 25, the statistical information calculated dynamically can be presented to the operator by the input circuit 410 and the display 420. That is, the operator can refer to the dynamically calculated statistical information if he/she has a tablet, a personal computer, or the like, even in a room different from the room in which the medical information display device 100 is installed, or in a different hospital. The data trend can be easily grasped.

In addition, in the above-described embodiment, the case where the statistical information about the vital data of the patient P1 is calculated has been described, but the embodiment is not limited to this. For example, the display control function 151 displays numerical data of a plurality of patients (for example, the patient P1, the patient P2, and the patient P3) in time series, and the calculation function 153 calculates statistical information from the numerical data included in the display period. To do. Then, the display control function 151 displays the statistical information about the numerical data of the patient P1, the patient P2, and the patient P3 by using a histogram, a box plot, or the like.

Here, for example, when the patient P1, the patient P2, and the patient P3 have the same case, the medical information processing system 1 can easily grasp the data tendency according to the case. Further, when the same kind of medicine is administered to the patient P1, the patient P2, and the patient P3, the medical information processing system 1 can easily grasp the data tendency according to the type of medicine to be administered.

In the above-described embodiment, an example in which each processing function described above is realized by the single processing circuit 150 has been described, but the embodiment is not limited to this. For example, the processing circuit 150 may be configured by combining a plurality of independent processors, and each processor may realize each processing function by executing each program. Further, each processing function of the processing circuit 150 may be implemented by being appropriately dispersed or integrated into a single or a plurality of processing circuits.
