Hereinafter, an embodiment of a medical information processing system will be described with reference to the drawings.

FIG. 1 is a diagram showing a configuration example of a medical information processing system according to this embodiment. As shown in FIG. 1, the medical information system 1 according to the present embodiment includes a plurality of medical institution systems 10 (10a to 10c) and an information providing server 20, and is communicably connected via a network N1. It The number of medical institution systems 10 connected to the network N1 is not particularly limited.

The medical institution system 10 is a system provided in each of medical institutions such as hospitals and inspection institutions (hereinafter collectively referred to as medical institutions). In the example shown in FIG. 1, the medical institution system 10a is the medical institution system of the hospital A, the medical institution system 10b is the medical institution system of the hospital B, and the medical institution system 10c is the medical institution system of the hospital C. Yes, the medical institution system 10d is the medical institution system of the hospital D. Each of these hospitals (medical institution systems 10a to 10d) is in a relationship of regional medical cooperation, for example, and it is possible to mutually refer to medical treatment data of a subject such as a patient.

Each of the medical institution systems 10 has, for example, a sample inspection system 11, an image diagnosis system 12, an electronic medical record system 13, a terminal device 14, and the like. The specimen inspection system 11, the image diagnosis system 12, the electronic medical chart system 13, and the terminal device 14 are communicably connected via the in-hospital network N2. The in-hospital network N2 is connected to the network N1 via a network device such as a router.

The sample test system 11 generates medical care data relating to a sample test performed on a subject and stores it in a storage circuit in the system. For example, the sample test system 11 generates medical care data including test values (numerical data) indicating the results of hematological tests and biochemical tests performed on a subject. In addition, the sample test system 11 provides the medical information data stored in the storage circuit to the information providing server 20.

The image diagnostic system 12 generates medical care data relating to the image diagnosis performed on the subject and stores it in a storage circuit in the system. Here, the image diagnosis is performed by an inspection using a CT image captured by an X-ray CT (Computed Tomography) device, an inspection using an MR image captured by an MRI (Magnetic Resonance Imaging) device, or an ultrasonic diagnostic device. An inspection using the captured ultrasonic image, an inspection using the X-ray image captured by the X-ray diagnostic apparatus, and the like are included. For example, the image diagnostic system 12 generates medical care data including inspection values (numerical data) such as a blood vessel diameter and a blood flow obtained by image diagnosis. Further, the image diagnostic system 12 provides the medical information data stored in the storage circuit to the information providing server 20.

The electronic medical record system 13 generates medical treatment data regarding a prescription and a nursing record performed on the subject and stores the medical treatment data in a storage circuit in the system. For example, the electronic medical chart system 13 generates medical treatment data including test values (numerical data) of the subject's vitals (pulse, heart rate, respiratory rate, blood pressure, body temperature, etc.). Further, the electronic medical chart system 13 provides the medical information data stored in the storage circuit to the information providing server 20.

The medical care data generated by each of the specimen inspection system 11, the image diagnosis system 12, and the electronic medical chart system 13 described above includes the following information in addition to the inspection value corresponding to the measurement value. For example, the medical care data includes information such as the date and time when the test was performed (measurement date and time), the type of test (test type), the unit of the test value, and an abnormality flag indicating normality or abnormality.

The medical care data also includes a patient ID that can uniquely identify the subject. The patient ID may be the same for each medical institution or different for each medical institution. However, in the latter case, for example, by correlating the patient IDs of the medical periods relating to the same person with each other, it is possible to identify the subject of the same person from the patient IDs of the medical institutions. To do.

In addition, the medical care data includes information that can uniquely identify the medical institution that performed the test, as information indicating the environment in which the test of the subject was performed (test environment).

The information included in the medical care data is not limited to the above example. For example, the medical care data may include information regarding the subject such as sex and age, BMI (Body Mass Index), smoking/drinking habits, and the like. Further, the medical care data may include, as the examination environment, information that can identify the device used for the examination, information that can identify the reagent used for the examination, and the like. Further, the medical care data may include the date and time when the sample is collected.

The terminal device 14 is a computer device such as a PC (Personal Computer) or a tablet terminal used by a medical worker such as a doctor, a nurse, or a laboratory technologist. As shown in FIG. 1, the terminal device 14 has an input circuit 141 and a display 142. The input circuit 141 receives an input operation from the operator. For example, the input circuit 141 is realized by a trackball, a switch button, a mouse, a keyboard, a touch panel, or the like. The display 142 displays various data. For example, the display 142 is realized by a liquid crystal monitor, a CRT (Cathode Ray Tube) monitor, a touch panel, or the like. The input circuit 141 and the display 142 may be integrated. For example, the input circuit 141 and the display 142 may have a touch panel configuration.

The medical staff can access each system in his/her medical institution through the terminal device 14. In addition, the medical staff can access the information providing server 20 via the terminal device 14. When the information providing server 20 is accessed, the medical institution ID of the medical institution in which the terminal device 14 is installed and the information capable of identifying the user (medical worker) operating the terminal device 14 are transmitted to the information providing server 20. Shall be done.

The information providing server 20 acquires various types of medical care data from each of the medical institution systems 10 via the network N1, and performs various types of information processing using the acquired medical care data. For example, the information providing server 20 is realized by a computer device such as a server device or a workstation. The information providing server 20 is not limited to a single device, and may be realized by cooperation (for example, cloud computing) of a plurality of network-connected computer devices.

FIG. 2 is a diagram showing an example of the configuration of the information providing server 20. As shown in FIG. 2, the information providing server 20 has a communication interface 210, a storage circuit 220, and a processing circuit 230.

The communication interface 210 is connected to the processing circuit 230, and controls transmission and communication of various data performed between the information providing server 20 and each medical institution system 10. Specifically, the communication interface 210 receives medical care data from each medical institution system 10 and outputs the received medical care data to the processing circuit 230. The communication interface 210 is realized by, for example, a network card, a network adapter, a NIC (Network Interface Controller), or the like.

The storage circuit 220 is connected to the processing circuit 230 and stores various data. Specifically, the storage circuit 220 stores various programs executed by the processing circuit 230 and various setting information regarding the operation of the information providing server 20. Further, the storage circuit 220 holds an examination result DB 221 corresponding to the storage unit of the present embodiment for storing the medical care data received from each medical institution system 10. The storage circuit 220 is realized by, for example, a RAM (Random Access Memory), a semiconductor memory element such as a flash memory, a hard disk, an optical disk, or the like. The inspection result DB 221 is not limited to be stored in the storage circuit 220, and may be stored in an external device accessible by the information providing server 20.

The processing circuit 230 centrally controls the operation of the information providing server 20. The processing circuit 230 is realized by a processor such as a CPU (Central Processing Unit).

The processing circuit 230 also includes a collection function 231, a detection function 232, a determination function 233, an acquisition function 234, and a display control function 235. The determination function 233 is an example of a determination unit. The acquisition function 234 is an example of an acquisition unit. The display control function 235 is an example of a display control unit.

The collection function 231 collects medical care data from each of the medical institution systems 10. Specifically, the collection function 231 collects the medical care data provided from each of the specimen inspection system 11, the image diagnosis system 12, and the electronic medical chart system 13 of each medical institution system 10. Then, the collection function 231 stores the collected medical care data in the examination result DB 221 of the storage circuit 220.

FIG. 3 is a diagram showing an example of the data structure of the medical care data stored in the examination result DB 221. As shown in FIG. 3, the medical care data includes a patient ID, a measurement date and time, a test type, a test value, a unit, an abnormality flag, and a test environment ID as data items. The medical care data shown in FIG. 3 shows an example of medical care data collected from the sample test system 11 of each medical institution system 10.

In FIG. 3, the patient ID is information that can uniquely identify the subject. The measurement date and time is the date and time when the test of the subject was performed. The examination type indicates the type of examination performed on the subject. The test value is a test value (numerical data) of the subject obtained by the test. The unit is a physical unit that represents the quantity of the inspection value. The abnormality flag is information set by the medical institution, and is information indicating whether or not the inspection value is normal. It should be noted that in FIG. 3, the blank column of the abnormality flag means that it is determined to be normal. Further, the examination environment ID stores information that can identify the medical institution that performed the examination. Note that FIG. 3 shows an example in which a hospital name is stored as the examination environment ID.

Returning to FIG. 2, the detection function 232 detects a characteristic value for each examination environment (medical institution) registered in the examination environment ID and each examination type, based on the medical care data stored in the examination result DB 221. Here, the characteristic value represents the tendency of the inspection result. Hereinafter, the inspection environment is also simply referred to as a medical institution.

Specifically, the detection function 232 detects the characteristic value indicating the tendency of the test result for each medical institution (test environment ID) and test type based on the test value and the state of the abnormality flag included in the medical care data. Here, the detection function 232 calculates the frequency distribution of the inspection values for each medical institution and each inspection type, and sets the representative value such as the average value, the median, and the mode value obtained from the frequency distribution as the first characteristic value. To detect. In addition, the detection function 232 is based on the relationship between the test value and the abnormality flag included in the medical care data, the reference range relating to the state determination of the subject at each medical institution, or the range of the test value capable of specifying the reference range. Is detected as a second characteristic value. For example, the detection function 232 detects a second characteristic value related to various state determinations such as determination of normality/abnormality and determination of caution and follow-up. Hereinafter, a method of detecting the above-mentioned first characteristic value and second characteristic value will be described. In the present embodiment, for simplification of description, a method of detecting a second characteristic value related to normal/abnormal determination will be described.

When detecting the first characteristic value, the detection function 232 divides the medical care data stored in the examination result DB 221 into medical environments and examination environments. Next, the detection function 232 generates a frequency distribution that represents the relationship between the test value included in the medical care data and the frequency with which the test value appears based on the classified medical care data.

FIG. 4 is a diagram for explaining the operation of the detection function 232, showing a frequency distribution showing the relationship between the inspection value and the frequency. Here, FIG. 4A shows the frequency distribution of the test values related to the medical institution “Hospital A”, and FIG. 4B shows the frequency distribution of the test values related to the medical institution “Hospital B”. It is supposed to be shown. In FIG. 4, the test value of the test type HDL-cholesterol (HDL-C) is the target of analysis.

Then, the detection function 232 detects a representative value such as an average value or a median value calculated by statistically analyzing the frequency distribution as the first characteristic value. For example, when the detection function 232 calculates the median value “49” from the frequency distribution shown in FIG. 4A, the median value “49” is associated with the medical institution “Hospital A” and the examination type “HDL-C”. It is detected as the first characteristic value. Further, when the detection function 232 calculates the median value “45” from the frequency distribution shown in FIG. 4B, the median value “49” is associated with the medical institution “Hospital B” and the examination type “HDL-C”. It is detected as the first characteristic value. The detected first characteristic value is stored in the storage circuit 220 or the like in association with the corresponding medical institution and examination type.

On the other hand, when detecting the second characteristic value, the detection function 232 divides the medical care data stored in the examination result DB 221 into medical environments and examination environments, similarly to the first characteristic value described above. Next, the detection function 232 identifies the upper limit value and the lower limit value of the inspection value in which the flag indicating abnormal (or normal) is set, among the classified medical data. Then, the detection function 232 detects each of the specified upper limit value and lower limit value as the second characteristic value capable of specifying the reference range related to the normal/abnormal determination of the inspection value.

Here, to explain with reference to FIGS. 4A and 4B, the detection function 232 determines that the upper limit of the inspection value in which the flag indicating abnormality is set from each medical care data set related to the frequency distribution of FIG. 4A. The value "121" and the lower limit value "44" are specified. Further, the upper limit value “120” and the lower limit value “29” of the inspection value in which the flag indicating the abnormality is set are specified from each medical treatment data related to the frequency distribution of FIG. 4B.

Then, the detection function 232 uses the values of the upper limit value and the lower limit value of FIG. 4A to specify the reference range R1 (44<R1<121), the medical institution “hospital A” and the examination type “HDL-C”. Is detected as the second characteristic value. In addition, the detection function 232 can specify the upper limit value and the lower limit value of FIG. 4B as the reference range R2 (29<R1<120), which is a medical institution “hospital B” and an examination type “HDL”. -C" as the second characteristic value. The detected second characteristic value is stored in the storage circuit 220 or the like in association with the corresponding medical institution and examination type.

In the above example, the characteristic value is detected in units of the medical institution and the inspection type. However, when the inspection environment (inspection environment ID) is set in more detail, the characteristic value is detected in the detailed unit. May be. For example, when the medical care data includes information that can identify the medical institution as well as the device and the reagent used for the examination, the characteristic value may be detected for each device or reagent.

Further, the timing at which the detection function 232 detects the characteristic value is not particularly limited, and can be set arbitrarily. For example, the detection function 232 may detect the characteristic value at a preset timing. Further, for example, the detection function 232 may detect the characteristic value at the timing when the medical data reference request is received from the external device such as the terminal device 14.

Also, when the number of medical care data (sample number) is insufficient for statistical analysis, the characteristic value cannot be detected, or even if the characteristic value can be detected, the accuracy may be low. There is a nature. Therefore, when the number of classified medical data is less than the threshold value, the detection function 232 preferably stores the information indicating that the characteristic value is unknown in association with the corresponding medical institution and examination type. ..

Returning to FIG. 2, when the determination function 233 receives an access to its own device (information providing server 20) via the communication interface 210, the determination function 233 determines the medical institution to which the terminal device 14 of the access source belongs. Specifically, when the determination function 233 receives a reference request for medical care data from any of the terminal devices 14, the determination function 233 determines the medical institution to which the requesting terminal device 14 belongs. Hereinafter, the medical institution to which the request source terminal device 14 belongs is referred to as an access source medical institution. Also, other medical institutions other than the access source medical institution are referred to as non-access source medical institutions.

Here, the reference request includes a narrowing-down condition such as a patient ID and an examination type for designating medical care data for which reference is requested. Further, for example, the reference request may include information that can identify the requesting user or the medical institution.

For example, when the reference request includes information that can identify the medical institution, the determination function 233 determines that the medical institution identified by the information included in the reference request is the access source medical institution. Further, for example, the determination function 233 may determine the medical institution of the access source based on the IP address or domain of the terminal device 14 that has accessed the own device.

Further, for example, the determination function 233 may be configured to provide a login screen for inputting a user name and a password to the terminal device 14 and determine the medical institution that is the access source based on the information input on the login screen. In this case, for example, the determination function 233 authenticates the user based on the user name and password input on the login screen, and based on the data table or the like in which the user name and the medical institution are associated with each other, the user who has permitted the login. The medical institution corresponding to the given name can be specified.

The acquisition function 234 acquires from the examination result DB 221 the medical care data relating to the subject designated by any of the medical institutions (medical institution system 10). Specifically, the acquisition function 234 acquires, based on the narrowing-down condition included in the reference request, the medical care data corresponding to the narrowing-down condition from the examination result DB 221.

For example, when the patient ID and the examination type are designated as the narrowing-down conditions, the acquisition function 234 obtains the medical care data including the designated patient ID and the examination type from the examination result DB 221. Further, for example, when the patient ID is designated as the narrowing-down condition, the display control function 235 acquires the medical care data including the designated patient ID from the examination result DB 221.

The display control function 235 generates display data in which the inspection values included in the medical care data are arranged in chronological order based on the medical care data acquired by the acquisition function 234. Then, the display control function 235 provides the generated display data to the requesting terminal device 14 to display a screen corresponding to the display data on the display 142 of the terminal device 14.

Specifically, the display control function 235 classifies the medical care data acquired by the acquisition function 234 for each examination type, and arranges the test values included in each of the classified medical care data in chronological order. Here, when the inspection is performed over a plurality of medical institutions, the inspection values acquired by the plurality of medical institutions are arranged in time series in a mixed state. Then, the display control function 235 generates display data that represents the inspection values arranged in chronological order in a graph format.

Further, the display control function 235 attaches, to the inspection values arranged in chronological order, the information based on the characteristic value of the medical institution that acquired the inspection values in association with the above-described generation of the display data. Here, the information added to the inspection value can adopt various forms.

Hereinafter, a display form of a screen (hereinafter, inspection value transition screen) displayed by the display data generated by the display control function 235 will be described with reference to FIGS. 5 to 10.

FIG. 5 is a diagram showing an example of the display form of the inspection value transition screen. Here, the horizontal axis of the inspection value transition screen G1 represents the date when the inspection was performed, and the vertical axis represents the inspection value. In the examination value transition screen G1, the examination values of the examination data corresponding to the narrowing-down condition of the patient ID “P0001” and the examination type “HDL-C” in the examination data shown in FIG. 3 are arranged in chronological order (plot. ) Represents the result.

On the inspection value transition screen G1, the medical information of the non-access source is acquired based on the difference between the first characteristic value of the medical institution of the access source and the first characteristic value of the medical institution of the non-access source. An example is shown in which a value obtained by correcting the inspection value is displayed as information based on the characteristic value described above.

For example, when the determination function 233 determines that the medical institution of the access source is “Hospital B”, the display control function 235 determines that the first characteristic value relating to the medical institution “Hospital B” and the examination type “HDL-C”. To the reference value for correction. Next, the display control function 235 sets the set reference value and the first characteristic value related to the examination type “HDL-C” detected for each of the non-access source medical institutions “Hospital A, Hospital C, Hospital D”. And the calculated difference value is set as the correction amount. For example, if the first characteristic value (reference value) of hospital B is “45” and the first characteristic value of hospital A is “49”, the display control function 235 determines that the difference between both characteristic values is “−4”. Is set as the correction amount.

Next, the display control function 235, among the test values plotted in chronological order, the test values acquired at other medical institutions “Hospital A, Hospital C, Hospital D” other than the medical institution “Hospital B” that is the access source. Are corrected by the previously set correction amounts, and the corrected inspection value is added in a state in which it can be discriminated from the uncorrected inspection value. For example, if the inspection value of the hospital A is "44", the display control function 235 adds the correction amount "-4" to the inspection value "44" and plots the corrected inspection value "40". .. Then, the display control function 235 connects the inspection value acquired at the medical institution “hospital A” of the access source and the corrected inspection value with a line segment (solid line) in chronological order.

Points P11, P12, and P13 in FIG. 5 correspond to the uncorrected test values of 44 mg/dL, 58 mg/dL, and 50 mg/dL acquired in the examination of Hospital A, respectively, and points P11′, P12′, and P13′ are , Corresponding to the corrected test values of 40 mg/dL, 54 mg/dL, and 46 mg/dL obtained by correcting the test values of the points P11 to P13 with the correction amount “−4”. Also, the point P14 is
It corresponds to the test value of 65 mg/dL acquired in the test of the hospital B that is the access source. Further, the point P15 corresponds to the uncorrected test value 111 mg/dL acquired in the examination of the hospital C, and the point P15′ is the corrected test value obtained by correcting the test value of the point P15 with the correction amount “+3”. Corresponds to 114 mg/dL. Further, the point P16 corresponds to the inspection value of 65 mg/dL acquired in the inspection of the hospital D.

Here, the display color is different between the point before correction (P11, P12, P13, P15) and the point after correction (P11', P12', P13', P15'), and the inspection value after correction and before correction It is possible to distinguish from the inspection value of. More specifically, the corrected points (P11, P12, P13, P15) are displayed in the same display color as the point P14 related to the hospital B that is the access source.

Thereby, the user observing the test value transition screen G1 can easily distinguish the test value acquired by the test of his medical institution from the test value acquired by the test of another medical institution. Further, the user can easily identify whether the test value is before correction or after correction based on the difference in the display color of the test value acquired by the inspection of another medical institution. In addition, the user can intuitively understand the difference between the inspection result at the medical institution and the inspection result before and after the correction, so that the inspection environments can be easily compared.

Note that, in FIG. 5, a point P16 is a display example of an inspection value in which the characteristic value (first feature amount) of the inspection environment is unknown. As shown in FIG. 5, the point P16 is displayed in a display color different from that of the other points. In this way, the inspection value whose characteristic value is unknown can be displayed in a form different from the other inspection values, so that the user's attention can be called. Further, as for the inspection value whose characteristic value is unknown, for example, as shown in FIG. 6, the inspection value may be connected by a line type different from the line segment connecting the detected inspection values.

Here, FIG. 6 is a diagram showing a modification of the inspection value transition screen shown in FIG. 5, and shows the same display contents as in FIG. In the inspection value transition screen G2 of FIG. 6, as a difference from the inspection value transition screen G1, a line segment connected to an inspection value (point P16) whose characteristic value is unknown is shown by a broken line. Thereby, the inspection value whose characteristic value is unknown can be emphasized, so that the user's attention can be called.

Further, the inspection value transition screen is not limited to the one based on the first characteristic value, but may be one using the second characteristic value. For example, as shown in FIG. 7, the reference range specified by the second characteristic value may be added to each inspection value plotted in time series as information based on the characteristic value described above.

Here, FIG. 7 is a diagram showing an example of the display form of the inspection value transition screen. The test value transition screen G3 shown in FIG. 7 is based on the same conditions as in FIG. 5 (patient ID “P0001”, test type “HDL-C”, access source “hospital B”).

In the case of this display form, the display control function 235 causes each of the test values plotted in chronological order to display the second characteristic value related to the medical institution and the test type from which the test value was acquired. Further, the display control function 235 displays the second characteristic value relating to the medical institution of the access source and the second characteristic value relating to the medical institution of the non-access source in a distinguishable state.

Specifically, as shown in FIG. 7, with respect to the inspection values of the points P11 to P16 plotted in chronological order, range bars B11 to B15 representing reference ranges specified by the corresponding second characteristic values are displayed. Display in association with each other. Here, the display colors of the points P11 to P15 and the range bars B11 to B15 are different for each medical institution.

For example, the inspection value (points P11 to P13) and the second characteristic value (B11 to B13) related to the hospital A, and the inspection value (point P14) and the second characteristic value (B14) related to the hospital B that is the access source. Are displayed in different display colors. Further, the inspection value (point P14) and the second characteristic value (B14) related to the hospital B that is the access source and the inspection value (point P15) and the second characteristic value (B15) related to the hospital C are displayed differently. It is displayed in color. On the other hand, the display color of the line segment connecting the respective inspection values is unified to the same display color as the inspection value (P14) of the medical institution (hospital B) that is the access source. Note that the point P16 in FIG. 7 is a display example of an inspection value whose characteristic value is unknown, similar to the point P16 in FIG.

Thereby, the user observing the test value transition screen G3 can easily identify the test value acquired by the test of his medical institution and the test value acquired by the test of another medical institution. Further, since the user can intuitively understand the difference between the reference range (range bar) displayed on the inspection value transition screen G3 and the reference range at his/her medical institution, comparison between inspection environments can be facilitated. It can be carried out.

Further, for example, as a modified example of the test value transition screen G3 shown in FIG. 7, the display form of the second characteristic value (reference range) relating to the medical institution of the access source is changed to the second characteristic value relating to the medical institution of the non-access source. It may be displayed in a form different from the characteristic value.

For example, as shown in the inspection value transition screen G4 of FIG. 8, by displaying the range bar B14 related to the medical institution of the access source over the entire period, the second characteristic value related to the medical institution of the access source is further emphasized. 8 is a diagram showing a modification of the inspection value transition screen shown in FIG. 7, and shows the same display contents as in FIG.

In this way, by changing the display form of the second characteristic value between the medical institution of the access source and the medical institution of the non-access source, the second characteristic value relating to the medical institution of the access source can be emphasized. In addition, since it becomes easy to compare the reference range used by the medical institution of the access source and the reference range used by the medical institution of the non-access source, the convenience for the user can be improved.

As another display form, the normal/abnormal determination result of the inspection value of the non-access source medical institution, which is determined based on the second characteristic value (reference range) of the access source medical institution, is used as the inspection value. It may be displayed in addition to the transition screen.

When realizing this display form, the display control function 235 determines whether or not each of the test values plotted in chronological order is included in the reference range of the second characteristic value related to the medical institution that is the access source. Then, the normal/abnormal determination (first determination) is performed. In addition, the display control function 235 determines whether or not each of the test values plotted in chronological order is included in the reference range of the second characteristic value related to the medical institution in which the test value is acquired. , Normality/abnormality determination (second determination). It should be noted that the second determination is not performed and the value of the abnormality flag recorded in the medical care data is used.

The display control function 235 compares the determination results of the first determination and the second determination, and, for example, an inspection value in which the determination result is different between the first determination and the second determination, the first determination and the second determination. The inspection value and the like that are both determined to be abnormal in the determination of 2 are extracted. Then, as shown in FIG. 9, the display control function 235 causes the extracted inspection value to be displayed by a display method different from other inspection values.

Here, FIG. 9 is a diagram showing an example of the display form of the inspection value transition screen. The test value transition screen G5 shown in FIG. 9 is based on the same conditions as in FIG. 5 (patient ID “P0001”, test type “HDL-C”, access source “hospital B”).

In FIG. 9, for example, the inspection value at the point P13 is normal because it is included in the range bar B13 when the range bar B13 associated with the inspection value is used as a reference. On the other hand, the inspection value at the point P13 is abnormal because it is outside the range bar B14 when the range bar B14 associated with the inspection value (P14) of the medical institution that has made the access is the reference. In such a case, as shown in FIG. 9, the display control function 235 makes the display color of the point P13 different from the display colors of the other points to perform the highlight display.

Further, for example, the inspection value of the point P11a is abnormal because it is outside the range bar B11 with reference to the range bar B11 associated with the inspection value. In addition, the inspection value of the point P11a is abnormal because it is outside the range bar B14 with reference to the range bar B14 associated with the inspection value (P14) of the medical institution that is the access source. In such a case, as shown in FIG. 9, the display control function 235 makes the display color of the point P13 different from the display colors of the other points to perform the highlight display.

As a result, the user observing the inspection value transition screen G9 has an inspection value in which the determination result is different due to the difference in the reference range between his own medical institution and another medical institution, or the determination result is abnormal in both medical institution. The inspection value can be easily identified.

As another display form, the inspection value transition screen using both the first characteristic value and the second characteristic value may be displayed. In this case, for example, the display control function 235 performs the correction of the inspection value based on the first characteristic value related to the medical facility that is the access source and the display of the second characteristic value, and thus is shown in FIG. Such an inspection value transition screen G6 can be displayed.

FIG. 10 is a diagram showing an example of the display form of the inspection value transition screen. The test value transition screen G6 shown in FIG. 10 is based on the same conditions as in FIG. 5 (patient ID “P0001”, test type “HDL-C”, access source “hospital B”).

As shown in FIG. 10, the inspection value transition screen G6 is a mixture of the display form of the inspection value transition screen G1 described in FIG. 5 and the display form of the inspection value transition screen G3 described in FIG. There is. Although FIG. 10 shows an example in which only the second characteristic value (range bar B14) related to the medical institution of the access source is displayed, the second characteristic value related to the medical institution of the non-access source is displayed as in the case of FIG. The characteristic value of may be displayed.

Although the display form of the inspection value transition screen has been described above, it is not limited to the examples of the inspection value transition screens G1 to G6 described above. The display forms of the inspection value transition screens G1 to G6 described above may be configured to be selectively designated. For example, any one of the inspection value transition screens G1 to G6 may be selectively displayed in response to an instruction from the user.

Next, the operation of the information providing server 20 will be described with reference to FIGS. 11 and 12.

Here, FIG. 11 is a flowchart showing an example of the characteristic value detection process executed by the information providing server 20.

First, the detection function 232 selects any one of the inspection environments (inspection environment ID: medical period) stored in the inspection result DB 221 as a processing target (step S11). Next, the detection function 232 reads the medical care data including the selected examination environment (step S12) and classifies the examination data by examination type (step S13).

Subsequently, the detection function 232 selects any one of the divided inspection types as the processing target (step S14). Next, the detection function 232 determines whether or not the number (sample number) of medical care data including the selected examination type is a predetermined value or more (step S15). Here, when the number of samples is equal to or larger than the predetermined value (step S15; Yes), the detection function 232 determines the characteristic values (the first characteristic value and the second characteristic value) based on the tendency of the inspection values included in the medical treatment data group. (Characteristic value of) is detected (step S16). Then, the detection function 232 stores the detected characteristic value in association with the inspection environment and the inspection type of the processing target (step S17), and proceeds to step S19.

On the other hand, when the number of samples is less than the predetermined value (step S15; No), the detection function 232 stores the information indicating that the characteristic value is unknown in association with the inspection environment and the inspection type of the processing target (step S15). S18) and the process proceeds to step S19.

Next, the detection function 232 determines whether or not all the examination types have been selected as the processing targets, and when there is an untreated examination type (step S19; No), the process returns to step S14 again. If all the inspection types are to be processed (step S19; Yes), the detection function 232 moves to step S20.

Subsequently, the detection function 232 determines whether or not all the inspection environments have been selected as the processing targets, and when there is an unprocessed inspection environment (step S20; No), the process returns to step S11 again. Further, when all the inspection environments are set as the processing targets (step S20; Yes), the detection function 232 ends this processing.

Through the above processing, the characteristic value representing the characteristic of the inspection environment is acquired for each inspection environment (medical institution) and inspection type stored in the inspection result DB 221. Note that, in FIG. 11, all the medical care data stored in the examination result DB 221 are targeted for processing, but the present invention is not limited to this. For example, the characteristic value may be detected from the medical care data of the medical institution every time a predetermined number of medical care data of each medical institution is stored in the examination result DB 221.

FIG. 12 is a flowchart showing an example of the information providing process executed by the information providing server 20. As a premise of this processing, it is assumed that the characteristic values for each medical institution and examination type have been stored by the processing described in FIG.

First, the determination function 233 waits until there is a reference request from any of the terminal devices 14 (step S31; No). When the determination function 233 receives the reference request from the terminal device 14 (step S31; Yes), the determination function 233 determines the medical institution to which the terminal device 14 belongs as the access-source medical institution (step S32).

Then, the acquisition function 234 acquires the medical care data requested by the reference request from the examination result DB 221 based on the narrowing-down condition included in the reference request (step S33).

Next, the display control function 235 reads the test values included in the medical care data acquired in step S33 in chronological order (step S34). Note that the display control function 235 performs the following processing for each examination type when a plurality of examination types are mixed in the medical care data acquired in step S33.

The display control function 235 determines whether or not the read test value has been acquired by the medical institution of the access source (step S35). When the read test value is acquired by the medical institution of the access source (step S35; Yes), the display control function 235 displays the test value by the first display method set for the medical institution of the access source. Plot (step S36) and move to step S40. When adding the second characteristic value, a range bar corresponding to the reference range of the second characteristic value is added in association with the inspection value plotted in step S36.

Further, when the read test value is acquired by the non-access source medical institution (step S35; No), the display control function 235 determines the characteristics of the non-access source medical institution from which the test value was acquired. It is determined whether or not the value is stored (step S37).

If the characteristic value is stored (step S37; Yes), the display control function 235 determines that the inspection value is corrected based on the difference between the characteristic values (first characteristic values) of the medical institutions of the access source and the non-access source. , The inspection value before correction is plotted by a second display method different from the first display method (step S38), and the process proceeds to step S40. In the second display method, the inspection values before and after the correction are displayed in a distinguishable manner. When adding the second characteristic value, the range bar corresponding to the second characteristic value is added in association with the inspection value plotted in step S38.

On the other hand, when it is determined that the characteristic value is not stored in step S37 (step S17; No), the display control function 235 performs the inspection by the third display method different from the first display method and the second display method. The values are plotted (step S39), and the process proceeds to step S40.

Subsequently, the display control function 235 determines whether or not both the inspection value read last time and the inspection value read this time are plotted by the first display method or the second display method (step S40). Here, when the characteristic values of both inspection values are plotted by the first display method or the second display method (step S40; Yes), the display control function 235 connects both inspection values with a solid line ( Then, the process proceeds to step S41) and step S43.

In addition, when at least one of both inspection values is plotted by the third display method (step S40; No), the display control function 235 connects both inspection values using a line type other than the solid line. (Step S42), the process proceeds to step S43.

Subsequently, the display control function 235 determines whether or not all the inspection values have been plotted, and when there is an unplotted inspection value (step S43; No), the process returns to step S34. On the other hand, when it is determined that all the inspection values have been plotted (step S43; Yes), the display control function 235 transmits the display data indicating the plot result to the terminal device 14 to display the display of the terminal device 14. The inspection value transition screen is displayed on 142 (step S44), and this processing ends.

As described above, in the present embodiment, the examination that stores the medical examination data obtained by associating the examination value obtained from the subject, the date and time when the examination value was obtained, and the information indicating the medical institution that obtained the examination value. From the result DB 221, the medical care data relating to the subject designated by the user is acquired. Then, in the present embodiment, the test values included in each of the acquired medical care data are arranged and displayed in chronological order, and a characteristic that represents the characteristics of the medical institution related to the acquisition of the test values with respect to the arranged test values. The information based on the value is added and displayed.

With this, the user can recognize the difference in the characteristics related to the acquisition of the inspection value at each medical institution based on the information based on the characteristic value added to each inspection value. Alternatively, it is possible to easily compare variations in the reference range. Therefore, in the present embodiment, it is possible to improve the convenience of displaying the measurement results measured by a plurality of medical institutions.

The embodiment described above can be appropriately modified and implemented by changing a part of the configuration or function of the information providing server 20. Therefore, some modifications of the above-described embodiment will be described below as other embodiments. In the following, points different from the above-described embodiment will be mainly described, and detailed description of points common to the content already described will be omitted. Further, the modified examples described below may be implemented individually or may be implemented in combination as appropriate.

(Modification 1)
In the above-described embodiment, an example in which the second characteristic value (reference range) is detected from the medical care data stored in the inspection result DB 221 has been described, but the reference range may be held in advance.

When this modification is applied, for example, as shown in FIG. 11, the information providing server 20 holds the reference range DB 222 storing the reference range for each inspection environment and each inspection item in the storage circuit 220. FIG. 13 is a diagram showing an example of the configuration of the information providing server 20 according to the first modification. The reference range DB 222 is not limited to be stored in the storage circuit 220, and may be stored in an external device accessible by the information providing server 20.

The reference range DB 222 stores a reference range in association with each inspection environment (medical institution) and each inspection item. For example, as shown in FIG. 14, the reference range DB 222 stores data items such as an inspection environment, an inspection type, a reference range, and a unit in association with each other. FIG. 14 is a diagram showing an example of the data structure of the reference range DB 222.

Here, the data items of the inspection environment, the inspection type, and the unit are the same as the data items of the same name included in the inspection result DB 221. The reference range corresponds to the reference range specified by the second characteristic value of the above-described embodiment, and is preset for each inspection environment and each inspection item. The reference range stored in the reference range DB 222 is not limited to the one set for each inspection environment and each inspection item, but may be a common reference range defined by guidelines or the like.

Further, in the present modification, the information providing server 20 (display control function 235) is based on the reference range stored in the reference range DB 222, instead of displaying the range bar based on the second characteristic value of the above-described embodiment. To display the range bar.

With such a configuration, the same inspection value transition screen as that of the above-described embodiment can be displayed, and therefore, the same effect as that of the above-described embodiment can be obtained. In addition, by using a common reference range defined by guidelines, etc., it is possible to understand how much the test results at each medical institution vary, based on the common reference range. The convenience of displaying the measurement result measured by the medical institution can be improved.

(Modification 2)
In the above-described embodiment, the test value (numerical data) obtained by the sample test is the display target, but the present invention is not limited to this, and the test value (numerical data) obtained by another test may be the display target. Good. For example, a test value (numerical data) obtained by a physiological function test such as an electrocardiogram or an electroencephalogram may be displayed. Further, the display target is not limited to the inspection value obtained by the inspection, but can be extended to the measurement value. For example, when the food intake of the subject is recorded as a measurement value (numerical data), the transition of the measurement value can be displayed by the method described above.

(Modification 3)
In the embodiment described above, the characteristic value is detected for each inspection environment and each inspection item, but as a further subdivision, a characteristic value may be detected for each characteristic of the subject. Here, the characteristics of the subject include, for example, sex, age, BMI (Body Mass Index), presence/absence of smoking/drinking habit, and the like. The characteristics of the subject may be included in the medical care data, or may be stored in an external database or the like in association with the subject identifier such as the patient ID.

In this modification, the information providing server 20 (detection function 232) detects a characteristic value for each characteristic of the subject in addition to the inspection environment and the inspection item. For example, the detection function 232 detects the characteristic value for each age of the subject. In this case, for example, since the reference range of the second characteristic value may change according to the age of the subject, the inspection value transition screen can be displayed by a display method suitable for the form of this modification. preferable.

FIG. 15 is a diagram showing an example of the display form of the inspection value transition screen according to the present modification. The test value transition screen G7 of FIG. 15 represents the transition of the heart rate of a specific child. The horizontal axis represents the age (age) of the child at the time of the examination, and the vertical axis represents the heart rate (beats/minute).

Point P21 corresponds to the test value acquired at hospital A when the child is one month old, point P22 corresponds to the test value acquired at hospital B when the child is six months old, and point P23 is Corresponds to the laboratory values obtained at Hospital A when the child was 2 years old. Then, in FIG. 15, range bars B21 to B23 corresponding to the second characteristic values of the medical institutions are displayed in association with the points P21 to P23.

Here, the range bar B21 corresponds to the second characteristic value related to the hospital A detected for the age of the newborn baby (0 month to 1 month), and the range bar B22 is detected for the age of 1 month to 12 months. The range bar B23 corresponds to the second characteristic value of the hospital B detected for the ages of 1 to 3 years, and the range bar B23 corresponds to the second characteristic value of the hospital B. In other words, on the inspection value transition screen G7, the range bar corresponding to the second characteristic value of the relevant age is displayed in association with the inspection value based on the age (monthly example) at which the child's inspection was performed.

In addition, FIG. 15 illustrates an example in which the medical institution from which access is made is the hospital B, and the second characteristic value relating to the age of the newborn baby detected from the medical data of the hospital B is set as range bars B22a to B22a. It is displayed in association with the point P21. Similarly, the second characteristic values related to the ages of 1 to 3 years old detected from the medical data of the hospital B are displayed as range bars B22b to B22b in association with the point P23.

With such a configuration, the reference range corresponding to the characteristics of the subject such as the age of the subject can be displayed in association with the inspection value, and thus the reference range suitable for the characteristics of the subject is used as an index. be able to. In addition, by displaying the reference range of the reference medical institution and the reference range of other medical institutions in a comparable state, it is possible to show how much variation in the test results at each medical institution is caused for each characteristic of the subject. You can easily understand if there is. Therefore, it is possible to improve the convenience of displaying the measurement results measured by a plurality of medical institutions.

(Modification 4)
In the above-described embodiment, the range specified by the two values of the upper limit value and the lower limit value is set as the reference range, but the present invention is not limited to this, and each range specified by three or more values may be set as the reference range.

FIG. 16 is a diagram showing an example of the display form of the inspection value transition screen according to the present modification. Here, the test value transition screen G8 of FIG. 16 represents the transition of the result of the pathological examination performed on the specific subject. The horizontal axis represents the date when the inspection was performed, and the vertical axis represents the inspection value.

As shown in FIG. 16, the test value transition screen G8 shows an example in which three-level reference ranges of negative, positive (low expression) and positive (high expression) are defined. In this case, the information providing server 20 (detection function 232) can detect the threshold value B32 of each stage from the result of the pathological examination included in the medical care data, and detect the threshold value B32 as the second characteristic value.

In addition, in the test value transition screen G8, an example in which the medical institution that made the access is "Hospital B" is shown, and the point P32 corresponds to the test value acquired at Hospital B. The uncorrected inspection values of the non-accessing medical institutions “Hospital A” and “Hospital C” are represented by points P31 and P33, and the corrected values are represented by points P31′ and P33′.

With such a configuration, even in the inspection in which the reference range is defined in multiple stages, it is possible to display the inspection value transition screen similar to that of the above-described embodiment, and thus the same as in the above-described embodiment. The effect of can be produced.

(Modification 5)
In the above-described embodiment, the inspection values whose characteristic values have been detected are connected by using solid lines, but the present invention is not limited to this. For example, even if the characteristic value is an already detected inspection value, if the inspection value corresponds to a statistical outlier, the inspection value is an outlier by connecting using different line types and display colors. May be displayed in a distinguishable manner.

FIG. 17 is a diagram showing an example of the display form of the inspection value transition screen according to this modification. The horizontal axis of the inspection value transition screen G9 represents the date when the inspection was performed, and the vertical axis represents the inspection value. Further, each of the points P41 to P45 corresponds to the inspection value acquired by a plurality of medical institutions, and each of the range bars B41 to B45 has the second characteristic related to the medical institution from which each inspection value was acquired. Corresponds to the value. In addition, it is assumed that the characteristic values of all the inspection values have been detected.

Here, of the points P41 to P45, for example, when the point P43 corresponds to an outlier, the information providing server 20 (display control function 235) sets the line segment connected to the point P43 to another line segment. By using different line types, the point P43 is displayed in an identifiable manner as an outlier. The method for determining whether or not the value is an outlier is not particularly limited, and a known technique in the field of statistics or the like may be used.

According to such a configuration, among the test values tested by each medical institution, the test value corresponding to the outlier is displayed so that it is identifiable as an outlier, and the user's attention is called for. You can Therefore, the user can easily exclude the test result having low reliability from the analysis target, and the convenience can be improved.

(Modification 6)
In the above-described embodiment, the mode in which the inspection value is corrected based on the access source medical institution is described, but the medical institution serving as the reference is not limited to this. For example, when the user designates a reference medical institution, the inspection value may be corrected based on the designated medical institution.

(Modification 7)
In the embodiment described above, the information providing server 20 detects the characteristic value of each medical institution, but the present invention is not limited to this. For example, each of the medical institution systems 10 may be configured to detect the characteristic value from the medical care data acquired by its own medical institution. Further, for example, a device external to the medical information processing system may detect the characteristic value of each medical institution. When the characteristic value is detected outside the information providing server 20, the information providing server 20 executes the above-described processing using the characteristic value detected by the external device.

(Modification 8)
In the above-described embodiment, the form in which the information providing server 20 is provided on the network N1 independent of each of the medical institution systems 10 has been described, but the installation position of the information providing server 20 is not limited to this. For example, the information providing server 20 may be installed in each of the medical institution systems 10. Further, some or all of the functions (collection function 231, detection function 232, determination function 233, acquisition function 234, and display control function 235) of the information providing server 20 are, for example, the terminal device 14 or the like, a medical information processing system. Any of the above devices may be provided.
