As an example, the medical examination status given by the status management unit 230 is “Mirai Hospital”, which indicates that the patient has not yet visited the hospital, “Medical Visit” that indicates that the patient has been received by the general reception terminal 40, and reception of each department. "Waiting for medical examination", which indicates that the examination has been completed before the medical examination after finishing each medical treatment at the terminal 50 or each medical treatment reception terminal 50, in order to perform the examination during the medical examination The status includes "temporary end", which is a state in which the examination is temporarily finished, and "end examination", which indicates a state in which the examination is completed. However, these are merely examples, and the medical examination status may be appropriately changed depending on the operation. For example, in the case of a medical institution that does not have a reception desk for each department, the status of "waiting for medical examination" may be given when the reception is completed at the general reception terminal 40.

[Operation of Information Processing Device 10]
Hereinafter, the operation of the information processing device 10 in the electronic medical chart system 1 shown in FIG. 4 will be described.

First, the information processing apparatus 10 acquires a user's account (personnel identification information for identifying each medical staff) and password via an input reception screen (not shown), and logs in the electronic medical chart system 1 using the login authentication unit 210. Perform authentication.

When login authentication ends normally, the list acquisition unit 110 of the information processing device 10 acquires information indicating the installation location of the information processing device 10 by referring to the terminal information TBL330, and based on the acquired information, the information processing device. It is determined whether 10 is a terminal used in an outpatient consultation room (outpatient consultation room terminal) or a terminal used in a ward (ward terminal). Specifically, the terminal information TBL330 in the example of FIG. 7 stores information indicating that the information processing device 10 of T001 is provided in the internal medicine outpatient room and the information processing device 10 of T002 is provided on the third floor of the south ward. doing. Each information processing apparatus 10 can acquire the information of the installation location by using the terminal identification ID assigned to itself, and can determine whether it is an outpatient consultation terminal or a ward terminal. Further, not limited to this, for example, information indicating whether the terminal is an outpatient consultation room terminal or a ward terminal is preset in each information processing device 10, and the list acquisition unit 110, based on the set information, The information processing apparatus 10 may be configured to determine whether the terminal is an outpatient consultation room terminal or a ward terminal. When the installation location of the information processing device 10 is an outpatient consultation room or the like, the list display unit 110 acquires the list data of the outpatients because the screen that is mainly displayed is the chart of the outpatients. Specifically, the list acquisition unit 110 refers to the outpatient consultation reservation TBL 340 and acquires list data of outpatients who have an appointment for consultation on the day. When the information processing apparatus 10 is a ward terminal, the screen to be displayed is mainly the chart of inpatients, and thus the list data of inpatients is acquired. Specifically, the list acquisition unit 110 refers to the inpatient TBL 350 and acquires inpatient list data. Note that the list acquisition unit 110 may be configured to receive input of search conditions via an input reception screen (not shown) and acquire list data of patients who match the search conditions.

The cache unit 120 generates and caches the chart screen data for the patients included in the list data acquired by the list acquisition unit 110. Then, as described in the first embodiment, the designation receiving unit 130 receives the designation of the patient for whom the chart screen is to be displayed, and the display processing unit 140 displays the chart screen of the designated patient on the display device 1041. To do.

Here, since the medical record data contains various information, the amount of information is large, and it may not be possible to secure a sufficient area when trying to cache the drawing data of the medical record screens of all patients included in the list. Conceivable. Therefore, the cache unit 120 of the present embodiment is configured to appropriately determine and select a patient whose cached chart screen should be cached, using various conditions. The example will be described below.

<For outpatient clinic terminals>
For example, an outpatient whose medical examination status is “waiting for medical examination” is a patient who will soon undergo medical examination, and there is a very high possibility that a medical chart screen will be displayed in the near future. Therefore, the cache unit 120 refers to the outpatient consultation reservation TBL 340 and is provided with information indicating that an outpatient whose consultation status is “waiting for consultation”, that is, an outpatient included in the list data, will soon receive a consultation. Selected outpatient as a target for caching the drawing data of the chart screen. In other words, when there are a plurality of statuses indicating the degree of progress of medical examination, the cache unit 120 selects a patient to which a status satisfying the criteria is given among the plurality of statuses. The “status that satisfies the criteria” here is a status that is the closest to the medical examination among the respective statuses that indicate the state before the medical examination is started. As a result, it is possible to reduce the number of chart data to be cached and to reduce the possibility that the area of the cache 106 is exhausted. In addition, the cache 106 can cache drawing data of a chart screen that is likely to be used in a medical examination. Therefore, it is possible to prevent the cache hit rate from decreasing due to the limitation of the cache target, and to maintain the effect of reducing the waiting time when the user displays the medical chart screen.

Further, in the example of FIG. 8, when an outpatient makes a medical examination appointment, the outpatient and the attending doctor are linked to each other. By using this information, it is possible to predict which patient's chart screen is likely to be displayed by a user (mainly a doctor) who logs in to the electronic chart system 1 and operates the information processing apparatus 10. Specifically, first, the cache unit 120 acquires information on the currently logged-in account (information identifying each medical worker). Then, the cache unit 120 refers to the outpatient consultation appointment TBL 340 using the acquired account and identifies the patient (patient ID) associated with the account. Then, the cache unit 120 selects the outpatient identified as described above among the outpatients included in the list data as a target for caching the drawing data of the chart screen. As a result, it is possible to reduce the number of chart data to be cached and to reduce the possibility that the area of the cache 106 is exhausted. In addition, the cache 106 can cache drawing data of a chart screen that is likely to be used in a medical examination. Therefore, it is possible to prevent the cache hit rate from decreasing due to the limitation of the cache target, and to maintain the effect of reducing the waiting time when the user displays the medical chart screen.

In addition, when a medical institution has multiple clinical departments, an outpatient consultation terminal is provided for each medical department, so it is possible to predict which patient's chart screen is likely to be displayed based on the medical department information. it can. Specifically, first, the cache unit 120 acquires information on the currently logged-in account (information identifying each medical worker). Then, the cache unit 120 refers to the doctor/nurse TBL 320 using the acquired account information, and acquires the information indicating the medical department to which the medical staff of the account belongs. Then, the cache unit 120 refers to the outpatient consultation reservation TBL 340 using the acquired information on the clinical department, and out of the outpatients included in the list data, the outpatient of the medical department corresponding to the information indicating the acquired medical department. Specify. Then, the cache unit 120 selects the outpatient identified as described above among the outpatients included in the list data as a target for caching the drawing data of the chart screen. As a result, it is possible to reduce the number of chart data to be cached and to reduce the possibility that the area of the cache 106 is exhausted. In addition, the cache 106 can cache drawing data of a chart screen that is likely to be used in a medical examination. Therefore, it is possible to prevent the cache hit rate from decreasing due to the limitation of the cache target, and to maintain the effect of reducing the waiting time when the user displays the medical chart screen.

Further, the upper limit of the screen to be cached may be preset in the cache unit 120. In this case, for example, the visit time of the outpatient can be used to prevent the cache hit rate from decreasing. Specifically, the cache unit 120 refers to the outpatient consultation appointment TBL 340 and acquires the visit time of the outpatient. Then, the cache unit 120 caches the drawing data of the chart screen for the patients included in the list data, in the order of the earliest visit times, up to a predetermined number. As a result, it is possible to reduce the number of chart data to be cached and to reduce the possibility that the area of the cache 106 is exhausted. In addition, outpatients with earlier visit times are more likely to receive medical examinations earlier, so by caching the chart data drawing data in the order of earlier visit times, the number of chart data drawing data to be cached is limited. Even the cache hit rate can be maintained.

In addition, some outpatients may come to the hospital without making an appointment for the day's consultation, such as when they make an initial medical examination or an emergency medical examination. In this case, the outpatient receives the day at the general reception terminal 40 or each department reception terminal 50. The cache unit 120 acquires from the general reception terminal 40 or each department reception terminal 50 the information on the day reception of the outpatient who came to the hospital without a medical appointment, and accordingly, the medical record screen of the outpatient who came to the hospital without a medical appointment is displayed. Cache drawing data. When the outpatient does not have a medical examination appointment at the first medical examination, for example, the template data of the chart screen held in advance is cached. If the outpatient is not the first visit but there is no medical appointment due to an emergency, the chart data is read based on the identification information of the outpatient obtained at the reception on the day, and drawing data for the chart screen is generated and cached. It In addition, a patient who does not have a medical examination appointment is added to the list data of the information processing device 10 in accordance with the acquisition of the information received on the day. As a result, the drawing data of the chart screen can be cached even for patients who do not have a medical appointment.

Further, the cache unit 120 may be configured to combine the above two or more and select a target to cache the drawing data of the chart screen.

<For ward terminals>
Moreover, as shown in the inpatient TBL350, when the medical staff in charge of each inpatient is managed on the electronic medical chart system 1, the possibility of being displayed on the electronic medical chart system 1 by using this information. High chart screen can be predicted. Specifically, the cache unit 120 acquires information on the currently logged-in account (information identifying each medical worker). Then, the cache unit 120 refers to the inpatient TBL 350 using the acquired account information, and identifies the inpatient associated with the medical staff of the account. Then, the cache unit 120 selects the inpatient identified as described above among the inpatients included in the list data as a target for caching the drawing data of the chart screen. As a result, it is possible to reduce the number of chart data to be cached and to reduce the possibility that the area of the cache 106 is exhausted. Further, the cache 106 can cache drawing data of a chart screen that is highly likely to be used. Therefore, it is possible to prevent the cache hit rate from decreasing due to the limitation of the cache target, and to maintain the effect of reducing the waiting time when the user displays the medical chart screen.

In the case of a ward terminal, it is possible to predict which patient's chart screen is likely to be displayed depending on the place where the ward terminal is provided. For example, in the case where the ward terminal is the terminal on the third floor of the south ward, there is a high possibility that the chart screen of the inpatient on the third floor of the south ward is displayed. Therefore, the cache unit 120 acquires the installation location by referring to the terminal information TBL330 using the terminal identification ID assigned to itself. Specifically, in the case of the information processing device 10 with the terminal identification ID "T002", the cache unit 120 uses the terminal identification ID "T002" and the installation location is "South Ward" as information for identifying each ward. Acquire information to the effect. The cache unit 120 may further acquire information indicating the number of floors of the ward (“3F” in the example of FIG. 7). As a result, the cache unit 120 acquires information that identifies the ward in which the information processing device 10 is installed. Then, the cache unit 120 refers to the inpatient TBL350 using the acquired information for identifying the ward, and the inpatient associated with the information for identifying the ward (for example, the inpatient in the "South ward", or "Inpatients on the 3rd floor of the South Ward" are specified. Then, the cache unit 120 selects the inpatient identified as described above among the inpatients included in the list data as a target for caching the drawing data of the chart screen. As a result, it is possible to reduce the number of chart data to be cached and to reduce the possibility that the area of the cache 106 is exhausted. Further, the cache 106 can cache drawing data of a chart screen that is highly likely to be used. Therefore, it is possible to prevent the cache hit rate from decreasing due to the limitation of the cache target, and to maintain the effect of reducing the waiting time when the user displays the medical chart screen.

Further, as shown in the attendance information TBL 360, when the attendance information including the patient the nurse is responsible for on the day is managed on the electronic medical chart system 1, by using the account information used at the time of login and this attendance information , It is possible to predict a chart screen that is likely to be displayed by the electronic chart system 1. Specifically, the cache unit 120 acquires information on the currently logged-in account (information identifying each medical worker). Then, the cache unit 120 refers to the attendance information TBL 360 by using the acquired account information, and obtains the attendance information on the day of the medical staff of the account. Then, the cache unit 120 selects an inpatient included in the acquired attendance information among the inpatients included in the list data as a target for caching the chart data drawing data. As a result, it is possible to reduce the number of chart data to be cached and to reduce the possibility that the area of the cache 106 is exhausted. Further, the cache 106 can cache drawing data of a chart screen that is highly likely to be used. Therefore, it is possible to prevent the cache hit rate from decreasing due to the limitation of the cache target, and to maintain the effect of reducing the waiting time when the user displays the medical chart screen.

Although it is desirable to clear the cached drawing data in accordance with the logout, the ward terminal can be used by an unspecified number of medical workers (nurses) because it is provided at a nurse station or the like. In this case, for example, by configuring the cache unit 120 to hold the drawing data that has been cached once for a predetermined time, it is possible to reduce the number of executions of the cache operation.

The function of each processing unit of the information processing apparatus 10 of the present embodiment is also realized by the CPU 101 executing the program stored in the storage 103, as in the first embodiment.

Although the embodiments of the present invention have been described above with reference to the drawings, these are merely examples of the present invention, and various configurations other than the above may be adopted.

Further, in the flowchart used in the above description, a plurality of steps (processes) are described in order, but the execution order of the steps executed in each embodiment is not limited to the order described. In each embodiment, the order of the illustrated steps can be changed within a range that does not hinder the contents. Further, the above description of the embodiments can be combined within a range that does not conflict.
