Things.

[0005]

In a hospital, most of the work to refer to the current and past accumulated information for diagnosis in a hospital is performed when a patient is diagnosed or when a diagnosis is performed prior to a test result. is there. In the former case, the time when the doctor refers to the information is known from the diagnosis schedule, and in the latter case, the time when the information is referred to from the examination schedule and the work schedule of the doctor is known. Therefore, the former schedule is monitored, the information for each patient is read out from the large-capacity storage / management device storing all the medical information on the network, and transferred to the storage device directly connected to the workstation for medical treatment. Means, means for selecting only information corresponding to the current medical care content of all medical information of the patient, and information indicating the location of the selected information on the mass storage / management device and selection information. By providing a means for creating an associated list, the above-described problem can be solved by transferring in advance only medical information that may be referred to to a storage device directly connected to the medical care workstation. . In the medical information providing system according to the present invention, the means for monitoring the information reference scheduler determines by what time the information should be prefetched, and, according to this, preprocessing for information prefetching described below. Start preemption. The means for selecting information is based on the diagnosis name, disease content, test items, etc. of the patient under medical care, and based on past information and related chart information.
And inspection data. Further, the list creating means creates a list indicating the location corresponding to the selection information so that the above selection information can be immediately read out from the mass storage / management device. This information selection and list creation are pre-processes for information prefetching, and are performed prior to prefetching using idle time of the computer such as at night. Thereby, the procedure for the pre-acquisition processing of the medical information can be simplified, and the processing time can be shortened. If the pre-acquisition and update of the medical information are sequentially performed in advance in the storage device directly connected to the medical treatment workstation in advance in correspondence with the reference date and the reference time of the medical information, the information request of the doctor can be completed in the shortest time. It becomes possible to provide information.

[0006]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 2 is a configuration diagram of a medical information providing system according to an embodiment of the present invention. In the figure, reference numeral 1 denotes an X-ray diagnostic apparatus for generating various modalities, a medical diagnostic apparatus typified by an ultrasonic apparatus, 2 a computer for managing the entire system, and 3 a diagnostic apparatus 1 and a work for a doctor or office. A large-capacity storage device group that stores and manages medical information input from a station (hereinafter, referred to as “WS”) 4 over a long period of time, and 6 is a relatively short-term medical information provided in each medical department. It is a storage device for the purpose of storage and management of data.
Normally, the storage device group 3 stores all medical information generated in the hospital and keeps it for a long time. On the other hand, the storage device 6 stores current and retrospective medical information of patients who are currently undergoing medical treatment (period) or who have received a reservation for a visit on the day. In the medical information providing system according to the present embodiment, necessary information is sequentially read from the local file of the storage device 6 in accordance with the order of acceptance of the patient's consultation and transferred to the storage device in the WS. If necessary information is stored in the storage device group 3, it is necessary to transfer the necessary information to the storage device 6 in advance. This is because it is difficult to secure a capacity for storing all medical information including the past of the patient examined on the day in the doctor's WS. That is, usually, the medical information per patient including the past medical information becomes enormous, and wasteful time is required for information transfer, and the storage device in the WS immediately overflows. For this reason, in the medical information providing system shown in the present embodiment, when generating a medical care schedule, the medical care purpose of the patient is included in the schedule, and the necessary information content, that is, the reference probability is referred to according to the medical care purpose and the medical care content. Only high information is selected, the amount of data request to the storage device 6 described above is reduced, and efficient information preparation is performed. With such a configuration, the occupation time of the storage device 6 and the transmission path 5 connected to the storage device 6 can be significantly reduced, and resources can be easily used for emergency data transfer for an unscheduled patient. A secondary effect is produced.

FIGS. 3 (a) to 3 (f) model the purpose and contents of visits to outpatients in the medical information providing system shown in this embodiment. The purpose of a patient's visit can be basically divided into six forms, and it is possible to determine reference medical information for each patient in accordance with each of the six forms. For example, in the case of (a), the case from the pre-examination to the examination and diagnosis is completed on the day, and in the case of the first examination, the information corresponding to the medical record of the past 5 years and the test results performed in the past 2 years can be immediately displayed. The information is prepared from the storage device 6 to the storage device of the WS 4. Other information is read directly from the storage device 6 in response to a doctor's request and displayed on the WS 4. In this case, a request for information to the storage device 6 is given higher priority than an information request to the storage device 6 for prefetching performed by another WS, and consideration is given to maintaining a man-machine response speed to the doctor. ing. Also, in the case of a return, the information corresponding to the current diagnosis content (including suspicion) is selected from the past medical record information up to 10 years ago and read from the storage device 6 and stored in the WS4 storage device. prepare. A similar selection is made for the inspection data, and the inspection data is prefetched from the storage device 6. In addition, only the medical treatment history is configured as an independent file so that the response can always be displayed immediately. In the case of FIG. 3 (b), a model is provided in which a pre-examination or consultation is made, and various examinations are reserved to open the patient. For the first consultation and the return visit, the same medical information is preempted as in the case of (a) described above, and preparations are made so that medical information can be immediately provided to the doctor. Hereinafter, the preparation of information is the same for (c) to (f). FIG. 3C shows a model in which an examination is performed and a medical examination is performed in a return after (a) or (b). FIG. 3D shows only the inspection, and the inspection result is shown in FIG.
And (f) is a model at the time of mass screening.

FIGS. 1A and 1B (hereinafter simply referred to as “FIG. 1”) are diagrams exemplifying the relation between a patient consultation form, representative information generated at that time, and a scheduler in the present embodiment. The column in FIG. 1 (a) shows the behavior of the patient, and is one of the most frequent medical forms in FIG. 3 (b),
(d) and (e). The column in FIG. 1B is representative of medical information generated during medical treatment. FIG.
Column (c) shows typical operation contents of the scheduler. Hereinafter, the operation will be described. At the time of the first outpatient outpatient reception 7, a patient ID number is prepared along with the patient's name, and thereafter the patient information generated in the hospital is managed and operated by this ID number. At the first consultation reception 7, basic patient information such as the date of birth and insurance content indicating the attributes of the patient is input and registered in the storage management unit. At this time, a schedule 8a for registering a future medical treatment schedule of the patient is generated. The schedule 8a shows the features of the present embodiment, in which an examination / re-examination schedule to be generated at the time of examination 9 and a selection key for information prefetching according to the present embodiment are registered as reference information at the next examination and examination. . Here, it is assumed that the diagnosis name (including suspicion) and the examination item are registered as information selection keys. After consultation 9, the patient finishes accounting and is released. Thereafter, the patient returns 10 for examination. By the morning of the return visit, the examination contents, examination purpose, etc. of the returning patient are pre-fetched in the local file (storage device 6 in FIG. 2) of the examination department (8b). An activation is performed to transfer the contents of the storage device 6 to the examination department WS4. If the dedicated file on the WS4 becomes empty as the medical treatment progresses, the transfer is executed immediately, and the reference display 11 at the time of the examination is immediately responded. It is controlled to be able to.
At the end of the examination, in the schedule 8c, patient information that is highly likely to be referred to for interpretation (for patients who have visited the past) or for subsequent examinations is selected from the patient's past medical information based on the selection key. Then, this is listed together with search information to be called from the mass storage device (storage device group 3 in FIG. 2) and the department management storage device 6.
The contents of this list are at the time of interpretation 13 or at a later date,
It is used when a patient returns for a consultation and receives a consultation. At the return visit 14 after the end of the examination, the scheduler prepares the local file (storage device 6) of the medical department by the morning of the day in the same manner as at the time of the examination, and has a high possibility of being referred to. The patient information is called from the mass storage device 3. Then, at the same time as the patient is returned, the transfer from the local file to the medical care WS4 is instructed while taking correspondence with the scheduler.
When the dedicated file No. 4 becomes available, the transfer is performed in accordance with the above-mentioned instruction, so that it is possible to immediately respond to the information request from the doctor. As shown here, information that is highly likely to be referred to is preempted so that system and network resources are freed up as much as possible. It is possible to provide a system with good responsiveness to the user.

FIGS. 4A and 4B show a procedure for selecting patient information that may be referred to during a medical examination. Reference to information going back in the past differs depending on the medical department and the disease content of the patient. In this case, this is clearly specified in the patient attribute item so that the selection criterion parameter can be uniquely specified. Basically, medical history data that is frequently referred to is treated as fixed reference data so that a man-machine response can always be made. Hereinafter, the selection flow will be described. FIG. 4A is an example of selecting chart information, and FIG. 4B is an example of selecting examination data. The scheduler determines whether the visiting patient is the first consultation for a new disease or is undergoing continuous medical treatment (step 21). In FIG. 4A, the first consultation selects the chart information for the past five years as information that may be referred to. (Step 22)
Select the chart information of ongoing medical care and the chart of the same diagnosis and the same case for the past 10 years (steps 23 and 2).
Four). Based on the selected information, a list is created in which the item and a parameter for search (for example, a location on a storage device) are paired (step 25) and passed to the scheduler shown in FIG.
(Step 26). As described above, the scheduler uses the list to send information from the mass storage device group 3 at the center to the local file 6 on the morning of the patient's visit.
To the doctor's WS4 in order according to the patient's visit, consultation waiting order, and the doctor's WS4 file availability. Similarly, in FIG. 4B, in the case of the first consultation, the test data of the past 5 years is selected as information that may be referred to (steps 31 and 32). Inspection data of the same type as the inspection item for 10 years is selected (steps 33 and 34). Thereafter, based on the selected information, a list is created in which the item and a parameter for search (for example, location on a storage device) are paired (step 35), and the list is passed to the scheduler shown in FIG.
After that, the same handling as in FIG. 4A is performed.

According to the above embodiment, the information search and transfer operation during the consultation time is performed within a limited range after the local file 6, so that the substantial transfer time can be greatly reduced. At the same time, the occupation time of the shared resource including the center file can be shortened, and the responsiveness to information search in an emergency can be improved. Further, since it is not necessary to collectively store patient information to be treated on the day in the nearest storage unit, it is possible to prevent the storage unit from increasing in capacity. It should be noted that the above-described embodiment is an example of the present invention, and it is needless to say that the present invention is not limited to this. For example, it can be easily analogized that a local file for each department is operated as a large-capacity storage / storage file between the file and the storage device of the WS. Further, if the inspection data is a multimedia including an image, it can be easily analogized to use the attributes of the diagnostic device, the diagnostic site, and the like for the information selection key.

[0011]

As described above in detail, according to the present invention, the information reference schedule is monitored to determine when the information should be prefetched, and the information prefetching should be performed accordingly. In this way, even if the information is relatively large-capacity information, it is displayed on the workstation in a short time in response to a request from a doctor or the like, by starting the pre-processing and the pre-fetching. Providing medical information
This has a remarkable effect of realizing the system .
