[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The basic concept of the present invention will be described below, and then specific embodiments will be described in detail with reference to the drawings.
As described above, in the hospital information system according to the present invention, various types of information in a hospital are classified and handled according to their properties. 1) Management information of the entire hospital (medical history, preservation chart, current in-hospital state, various masters) 2) Medical affairs and accounting information 3) Run state chart (direct operation information of doctor) 4) Active state chart ( 5) Inactive medical record (can be stored and active) 6) Order execution system (order contents, execution record, source file) 7) ward, Nursing information system 8) Other information sources and systems within departments 9) X-ray image utilization (interpretation and reporting) system 10) X-ray image generation, storage, preservation system, etc. These electronic information is converted into an online system through a network. In addition, information used in hospitals includes, in addition to the information related to direct medical treatment as described above,
There are so-called indirect medical information such as literature, conference information, case studies, papers, conferences, and communication records, and these various types of information can also be integrated into the overall system.

Hereinafter, the above 1) to 10) will be described in detail. 1) is management information related to the entire hospital, and includes information of several properties as described below. That is, the medical history management information, the state of the "inactive" medical chart described later, information indicating the current state in the hospital such as what information is where and where, and various types of master information. Centrally managing this information within the hospital means that the current state of the hospital, such as the status of many departments and subsystems within the hospital, the status of order processing and the distribution of medical records, etc., can be accurately monitored. Yes, including many subsystems as in the present invention, it becomes necessary only when the purpose of constructing an integrated hospital information system by electronically integrating information from these subsystems, and becomes essential in an integrated system. Things. 2) is medical information for the entire hospital. The medical information is information used for preparing a receipt based on the performed medical practice, and is related to almost all medical practices in the hospital. In other words, regardless of the department in which the medical procedure is performed, the medical information on the procedure must be collected and managed for each patient. Since these are information directly linked to the health system, they can be centrally managed in the hospital as a whole. It is reasonable to do. In order to download the medical information, each time a medical practice is performed in each department, the contents and results are transmitted directly from the source to the management system through the network. 3) to 5) are medical record information, which are classified according to their status. Here, "run" is a state in which the doctor is handling the medical record. That is, referring to the test information of the target patient, inputting the order, findings, and other medical information,
The doctor is operating the information or can easily operate the information. Specifically, it is a medical chart being processed or waiting for processing through the doctor workstation. “Active” is a medical chart that should be easily (in a short time) brought into the run state. Specifically, it is a chart of a patient who is currently undergoing medical treatment. This includes those for which no medical treatment (use of medical records) is scheduled on the day. “Inactive” refers to a patient's medical record for which the intended medical treatment has already been completed or a predetermined period has elapsed without performing a new medical treatment. From the above properties, in the hospital information system according to the present invention, “Run” manages medical record information to be placed on a workstation, and “Active” manages in a target clinical department in which medical care is performed, that is, is stored in each medical department storage file. Use medical record information as the local area network (branch line LA)
N), etc., the charts are quickly transferred to the workstation, and the charts containing the newly added information are easily transferred to the above-mentioned in-house storage file to make the charts reflect the latest information. is there.

[0008] In the hospital information system according to the present invention, when one patient is receiving a plurality of departments, an "active" chart is arranged for each department. New information generated in multiple departments is added to the same patient chart in other departments through the network. In other words, the “active” medical records of multiple departments always reflect the latest information of patients, including the contents of consultations of other departments. With this function, it is possible to prevent prescriptions and treatments in multiple departments from becoming invalid or adverse effects, which leads to improvement in the quality of medical treatment. Due to the above-mentioned properties, the “active” chart is a distributed chart management system for each medical department, in which the medical chart of the patient who is undergoing medical treatment at that time is stored in the medical department. On the other hand, the “inactive” chart is a stored chart, and some access time is allowed. Therefore, for storage, a collective optical file or the like having a sufficient capacity is used. In addition, "inactive"
In the medical chart, it is uncertain from which department the next use request is issued. Therefore, decentralized management in a specific medical department is not rational. Therefore, the “inactive” chart is centrally managed in the hospital. With this configuration, the medical department can keep the necessary medical records at hand and obtain the effect of use such as high-speed access and response characteristics, and at the same time, the problem that the file capacity becomes excessive due to unnecessary information and the problem of access. Solvable. On the other hand, by centralizing the "inactive" charts, filing efficiency can be increased and an economical system can be achieved. In addition, "inactive"
In many cases, there is no problem even if all of the medical records are not online.

6) Multimedia information (still images, waveforms,
Text information). The multimedia information corresponding to the patient is reflected in the “active” chart. In other words, the originator of the order has a transmission function for the destination of the order, and the receiving side of the order has a function of receiving the order to its own department, and also transmits the execution record and data etc. to the management department and the request source, etc. Has functions. The specific method of executing the order is executed independently in each department. 7) is a ward subsystem mainly based on a nursing information system for inpatients. The ward subsystem is the same as the medical department subsystem described above with regard to the management of medical records. In other words, the chart of the inpatient is "active"
Put it in the archive file of the ward. 8) is dedicated system information of a department other than the above or a specific department. These are managed and operated as closed systems in their departments except for connection to the network. A filing system for non-standardized information such as an analog image is an example of this. 9) and 10) are information related to radiology, and are generally PACS.
Is equivalent to a system called The order processing in the radiology subsystem is essentially the same as in the case of 6). However, the resulting image data is centrally managed as an image database. This is because of the large volume of radiographic images, the fact that traditional film-based systems have centralized film management for each patient,
Furthermore, it depends on the characteristics of the hospital business, such as involving intensive interpretation work by a specialist. This inherits the properties of the radiation image and the conventional operation method. Note that a storage and storage management method based on “active” and “inactive” can be applied to the radiographic image as in the above. As described above, in the hospital information system according to the present invention,
It is characterized in that management of information, placement of files and data (databases), restriction of access, and the like are optimally performed according to their respective properties. That is, optimization is to be carried out for the entire hospital, to be centrally managed, to be managed in a decentralized manner by the use department or generating department, and to optimize the use of concentration and dispersion according to time, place and condition. The information classification itself as described above expresses a high level of insight of the present invention based on examination of functions and properties of each department in the hospital from various aspects.

In the hospital information system according to the present invention, as described above, for example, the following functions are provided so that the medical department operates autonomously so as to function optimally in combination with decentralization and centralization. The system itself has it. (1) The intra-branch branch LAN has a network system in which intra-facility storage files and other databases and related information are combined. (2) It has a database server, a server for executing specific processing, and a workstation (WS) or terminal for inputting and outputting chart information. (3) Filing the active medical chart in the department storage file. (4) Connection between other subsystems and the unified management information system via a network (LAN). Further, the electronic chart system has the following functions as basic functions. (5) Import necessary information into own system through in-hospital information management system. (6) Take out the necessary patient chart. (7) Enter findings and other medical information into the chart. (8) Issue an order (convey the contents of the request to the department that executes the order). (9) Refer to medical history, test results and other related information. (10) Medical record information transmitted from the source to the own system
(The execution result of the order, etc.) is taken into a predetermined area of the corresponding chart. (11) Convert, process, and edit the data into a predetermined format or easy-to-read format. The basic functions of the electronic medical record are executed on a workstation (WS) or a server (S) in the medical department subsystem.

Hereinafter, the execution of medical treatment and the operation of each of the above functions will be described with reference to a medical department subsystem.
The medical treatment by the doctor is executed from the operation of opening the patient's chart on the WS in the above department. As described above, since the active medical record is in the in-house storage file, the doctor I
A target chart is opened by an initial operation using D (identification information) and a patient ID. The operation of opening the above-mentioned chart is,
To start an electronic medical record system. In the opened medical chart, in the case of a re-examination, there is a medical record up to the previous time, and in the case of a first consultation, only basic patient information is entered. The basic information is registered as centralized management information in a hospital at the time of reception.
The medical department subsystem fetches basic information from the unified management information through a network and creates the medical chart. Information generated through medical treatment is sequentially recorded on a medical record as electronic medical record system information on a WS. The order generated there is recorded in the chart and transmitted to the target department. The transmission to the target department does not necessarily have to be simultaneous with the order generation. Since the executed inspection data and the like have already been input into a predetermined area of the medical chart, they can be referred to in the form of the order and the result. An unexecuted order can be identified by displaying the effect. When the medical treatment is completed, the medical chart is closed. By this operation, the contents of the medical record are all stored in the in-house storage file as one of the active files, and the electronic medical record system on WS ends. Here, the medical treatment contents, treatment contents, and the like relating to the medical treatment are transferred to the medical affairs system. In the medical affairs system, only the medical affairs related information is taken out therefrom and processed. The filing information in the storage file is also transferred to the patient's chart in the storage file of another department if the patient is undergoing a plurality of departments. The information on the consultation for multiple departments is recognized through the unified management information in the hospital. With this function, the medical treatment progress and the latest state of the patient in other departments can be grasped, which leads to the realization of better medical care by grasping the overall condition of the patient. In addition, the contents of the medical record can be operated only with respect to the section related to the relevant department, and the medical record information of other departments can only be referred to and cannot be operated. As described above, the medical department subsystem can function autonomously as an independent unit. Therefore, it can be gradually added based on medical units of an appropriate size, or a server or W
S. It has features such as being able to be flexibly applied to various hospital scales by selecting the performance and scale of the file.

Next, a system on the order execution side will be described using an examination room as an example. When the order is received, it is registered in the scheduler of the own system, and thereafter the processing is executed according to the scheduler. The inspection data is stored in the source file, from which it is transferred to the requesting storage chart. Thereafter, the data on the medical record will be mainly used, and the source file after transfer will be left to the management of the laboratory. On the other hand, the contents of the execution are sent to the medical system. Further, the processing status of the order can be known from the contents of the scheduler. The relation between the radiology system, the order reception and processing, and the medical system is basically the same as that of the inspection system. However, due to the problem of transmission and storage of a large amount of image data, the source side is centrally managed as an image database. Although the image is basically referred to at the request source through image interpretation and its findings, the image data itself can be transmitted. Furthermore, the images can also be used in off-line applications, for example, by transporting films, optical or magnetic recording media. A high-speed transmission system (image LAN) is provided between the image database and the image interpretation terminal. However, if the requesting medical department also needs images, this is realized by extending the image LAN to the medical department. it can.
Furthermore, a system having a centralized management chart, which can be called a master chart, in addition to the above-mentioned distributed chart is also possible. In this system, since there are always a plurality of charts, the matching of the contents between the plurality of charts can be realized by mutually transferring the latest information of the charts through a network. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows the configuration of a hospital information system according to an embodiment of the present invention. In the figure, 1 is a host computer or server, 2 is a database, 3 is a medical affairs and accounting system, one subsystem of a hospital information system, 4 and 5 are clinical department subsystems representing several medical departments, and 6 is a clinical department subsystem. Laboratory subsystems representing various examination devices or systems, 7 a ward subsystem representing an inpatient ward, 8 a radiology subsystem representing a radiology function, and 9 a centralized management information of the entire hospital. A centralized management system that has a monitoring function for the entire hospital. Reference numeral 10 denotes an information network (LAN) connecting the subsystems, and reference numeral 100 denotes a branch LAN in the subsystems 4 to 8. Medical affairs subsystem 3
The host computer 1 executes processing such as downloading medical information generated from each department in a hospital online through the LANs 100 and 10 connected to each subsystem, and connecting to a receipt or an accounting system. The processing of this medical information is not particularly different from the conventional system. That is, the medical information is executed by the host 1 and the database 2, and the management is intensive. In addition, the database 2 centrally manages various master information and the status and status of each subsystem and chart in the hospital. Further, the stored medical chart information (inactive medical chart itself and related information) throughout the hospital is centrally managed. The medical department subsystems 4 and 5 basically function autonomously. In other words, the active charts related to the department are stored in the in-house storage chart file, and are managed separately for each department. Therefore, for example, when one patient is undergoing a medical examination in both the medical departments 4 and 5, the same medical record is placed in the archive file of each department. In addition, apart from the above-mentioned distributed medical chart, in the case of a hospital of an operation type provided with a master medical chart, there are always a plurality of medical charts even in a single department consultation. FIG. 2 shows the configuration within the medical department shown in FIG. Internal server (S) 40, internal file (F) 41, WS for doctor
42 and the like are connected by a branch line LAN 100. The in-facility file (F) 41 stores the active chart of the department. Further, the server (S) 40 stores the internal file (F) 4
1 and the medical record system through the doctor WS 42. Hereinafter, the operation in the medical department will be described.

FIG. 3 shows the procedure of medical treatment. First, the doctor activates the electronic medical record system with his / her and patient IDs through the WS 42 (steps 21 and 22). Thereby, the patient's chart is opened (step 23). That is, the medical record in the active state is retrieved from the in-facility storage file (F) 41 by the patient name, displayed on the WS, and becomes the run state. Here, the medical chart may be moved to the WS in advance according to the medical treatment schedule of the day, and may be in a run state. It should be noted that the medical record contains the medical records up to the previous time, and the doctor performs medical treatment based on the medical records. In the medical treatment, the WS refers to medical records and test data, processes such information, changes the display method, and the like on the WS. Furthermore, it issues new orders, comments, inputs observations, reviews reservations and examines medical plans (step 2).
Four). When an inspection or treatment order is issued, it is recorded in a medical chart and transmitted to each target department via a network (step 25). This control is performed by the server (S) 4
The electronic medical record system is composed of 0 and WS42.
The same applies to reservations and information addressed to other departments. In performing the above medical treatment, for example, the state of the examination and various devices,
It is necessary to refer to information such as the ward and reservation status (Step 2
6). These are confirmed through the hospital management information system. When the medical treatment is completed, the medical record is closed (step 27). That is, the run chart on WS42 is stored in the storage file (F) 4.
Return to 1. Here, if the patient has been examined in a plurality of departments, the contents of the storage file of the relevant department are also transferred to the storage files of other departments (step 28). In addition, multiple department consultation,
Confirm through the above-mentioned hospital management information system. Closing the chart ends the electronic chart system. FIG.
Shows the relationship between hospital management information and clinical departments. For the first-time patient, basic information of the patient is registered in the hospital management information system from the reception. For a returning patient, past data is added from the medical history database, a so-called medical chart cover is created, transferred to a predetermined medical department, and managed as an active chart. At the same time, this content is set in a chart status table (not shown), and the medical department in which the chart is located is displayed. The medical chart status table is a table reflecting the status of the order, the status of the reservation, the status of the examination apparatus, the status of the ward, and the like, and functions as a current status monitor in the hospital. In the hospital management information, in addition to the above, information on stored medical records, medical history information, information on a health system, and the like are integrally managed. Therefore, necessary information can be known from each subsystem in the hospital using predetermined information such as a patient name and an information name as a key.

FIG. 5 shows the relationship between the family storage file and the storage file. The active medical record during medical treatment is stored in the in-facility file, but if the medical treatment is completed or if the medical record is not accessed for a predetermined period, the medical record is transferred to the storage file and the medical record in the storage file is deleted. By this operation, the amount of the medical record in the storage file is limited to the one under medical care, and it is possible to avoid an excessive storage amount. In addition, the subsystem shown in FIG. 2 can be installed in consideration of the processing capacity of a medical unit or a subsystem,
Being able to respond flexibly to the size of the hospital and the contents of processing,
The feature is that it can be applied step by step. Next, the operation of the examination room subsystem 6 will be described. In FIG.
The hardware configuration will be described. The subsystem includes a server (S) 60, an inspection room file (F) 61, a WS 62, an inspection device or apparatus 64, an apparatus file (F) 63, a scanner 65, a photograph 66, and the like. FIG. 6 and FIG. 7 show the flow of processing of the examination room subsystem. When the order is received, it is registered in the scheduler (step 31), and thereafter, the inspection is executed according to the detailed specification of the order under the management of the scheduler (step 32). The inspection results are stored in the source file and transmitted to the requestor (steps 33 and 34). Here, as shown in FIG. 7, the examination contents are sent to the medical system, and the processing determined by the examination contents is performed. The examination data is sent to the requesting medical department, and is recorded as a result of the order in the corresponding chart in the storage file. This corresponds to attaching inspection data to a medical chart in a conventional paper chart. On the other hand, the order execution record is reflected in the order table of the in-hospital management information, indicating that the order has been executed. As described above, in the distributed chart system of the present invention,
The department has the function of issuing the order and transmitting the details to the order execution department and setting the occurrence of the order as in-hospital management information. On the other hand, the order execution department receives the order and sets it in the scheduler in its own subsystem.
It has a function of transmitting information to each subsystem of medical affairs, request source, and hospital management for each of the execution records. In the hardware configuration shown in FIG. 8, the transmission of the scheduler and the result to each subsystem is as follows.
The server 60 executes. The transfer may be performed in a unit such as one day, or may be performed in a unit. The data from the inspection device 64 may be digitized via a scanner 65 as shown in a photograph, for example, in addition to data that can be transmitted online. The ward system 7 also, apart from the specific processing contents inside its own subsystem, communicates information with the outside and the laboratory sub-system etc. basically with the above-mentioned medical department or laboratory sub-system and its combination. Does not change. In the above description, the case where the medical department and the examination room are independent subsystems has been described.However, it is common that there are some inspection devices in the medical department, and in this case, May be combined.

The radiology system 8 has the same basic functions as the inspection system with respect to the functions of receiving the order and transmitting the execution result information. However, image data is centrally managed as an image database in the radiology system.
That is, the source file in the case of the inspection system corresponds to a storage file of image data. In the radiology department, an image interpretation process is performed by a radiologist. In this case, the processing is intensively performed using a dedicated high-definition image interpretation terminal based on the database. This configuration and function may be based on conventional operation methods such as centralized film management and intensive image reading processing. An image is basically referred to by a request source with an interpretation result and its findings, but image data itself can be transmitted. The transmission of image data is performed through the network 10 or by extending a dedicated image LAN to a necessary department. In FIG.
2 shows the configuration of a radiology subsystem. The WS 83 and the file (F) 84 receive and schedule the order to the radiology department. In addition, WS85 is an inspection device (CT, MR
Various modalities) 86, 87 device files (F)
From 88, the image data is subjected to processing such as compression and stored in a centralized image database (IDB) 81. 80 is an image database server. Note that the image compression is performed by the transmission path 1
It may be executed in common by 30 parts or the server. 12
Reference numeral 0 denotes an image LAN, which is a high-speed transmission line because the traffic is larger than that of the input transmission line 130. An image display terminal (IDT) 82 is connected to the image LAN. The image display terminal 82 has a high-definition display device capable of displaying a large-capacity radiation image. Here, the functions of the interpretation and reporting system can also be performed. The radiation image can also be operated off-line by a portable medium 90 such as an optical disk. The image LAN 120 and the image display terminal 82 can be extended and used outside the department of radiology. FIG. 10 shows an overall configuration of a system in which this combination is extended to the entire hospital and can be used anywhere in the hospital, and FIGS. 11 to 13 show details of each unit. The WS 54 for doctors in the medical department 5 shown in FIG. 11 is a workstation provided with a high-definition display device for displaying images. In addition, 53 is an image file for the inside of a department and 52 is a server. Further, reference numeral 55 denotes an examination device provided in the department, which has a combined function of the department and the examination.

The configuration examples shown in FIGS. 10 to 13 are the basic configuration of the above-mentioned system, but there are various forms of the concrete execution method. In addition, depending on each form, LAN
It also affects basic characteristics such as traffic, response performance, and reliability. Hereinafter, examples thereof will be described. For example, each medical department has a patient's medical record, but may have a master medical record that aggregates the medical records of the entire hospital. In this case, an execution mode in which the contents of the distributed medical record are always matched, that is, a system in which the master medical record is always the same as the active medical record, and a system in which the contents of the master medical record at the time of distribution are possible. In the latter case, the latest patient information will only exist in the distributed chart.
In principle, the contents of the medical records that can be operated in medical departments are directly related to the relevant departments and are limited to only the information on the patient in charge of each doctor. Therefore, in the case of a patient attending multiple departments, the doctor in one department can refer to the latest medical treatment contents such as the test data and treatments of the patient in other departments, but input to the medical records of other departments. Operation is not allowed at all. Such control of the operable range can be realized by gate processing using a combination of a patient ID (identification code) and a doctor ID in charge. Further, in combination with other user confirmation means, the restriction function is further strengthened to maintain the confidentiality of the recorded contents, so that more advanced use is realized and the characteristics of computerization are further exhibited. Only with such consideration, medical information from other departments and past medical history data can be easily used with peace of mind, and use of patient information from a comprehensive perspective will lead to improvement in the quality of medical care. Becomes possible.

[0018]

As described above in detail, according to the present invention, it is possible to manage various types of information in a hospital in accordance with the characteristics of the source, the method of use, the user, the management method, and the like. This has a remarkable effect that a hospital information system that can be realized can be realized, and a hospital information system that can be integrated in a form suitable for hospitals of various sizes can be realized.
