BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a test history filing system, and in particular, for the purpose of improving the test accuracy in a clinical test center, the test history value of a patient for whom a test is requested and the test result value in this test. The present invention relates to a medical examination history filing system which provides an appropriate examination history value for performing collation with and can flexibly respond to a change in examination method.

[0002]

2. Description of the Related Art Among medical institutions, clinical laboratory centers are
The inspection is performed based on the request of the hospital or clinic, and the inspection result value is reported to the requesting hospital or clinic. That is,
It is an issue to carry out the inspection correctly, confirm the value of the inspection result, and then report it promptly. Therefore, use of quality control samples for the purpose of preventing mistakes in sample mixups and early detection of performance deterioration caused by failure of automatic analyzers that are performing automatic operation, deterioration of reagents, etc. Further, reference has been made to the past test result value of the patient, that is, the reference of the test history value. Hereinafter, the prior art will be described in detail by taking a patient having an inspection history value as shown in FIG. 11 as an example. In FIG. 11A, 011 indicates an inspection item code attached to each inspection item, 012 indicates an abbreviation of the inspection item, and 013 indicates an operation date when the inspection request is accepted. Here, as shown in FIG. 11B, the operation date is "N days" from noon on the Nth day to the noon of the next day, and "(N + 1) from noon of the (N + 1) th day to the noon of the next day. "Day". In addition, 014 is the presence or absence of a request for this inspection item this time, 015 is the inspection result value of this time, 016 is the inspection result value of two times before this request, and 017 is the one of the previous time as seen from this request. The inspection result value is shown.

Generally, with respect to the inspection items GOT and GPT for which the inspection request has been made this time, since the previous inspection result value is referred to as the latest inspection history value, "result D" and "(uninspected)" are displayed. It becomes relevant information. Then, by determining the difference or ratio between the “result D” and the “result F”, the validity of the inspection result value this time is judged. On the other hand, due to the recent rapid innovation of inspection and analysis technology, the inspection method for each inspection item is frequently changed.
The file that manages the attributes of each inspection item such as the abbreviation of inspection item, normal value, decimal point position, and unit was updated. In this case, only the latest attributes are managed on the file. Regarding this type of technology, for example, "Retest processing method in clinical test system" disclosed in JP-A-62-98262 and "Checking test data" in JP-A-5-181916. Techniques such as “method” are known. All of these techniques improve the accuracy of test results by comparing the initial test result value and the test result value at the time of retesting for the same test item when retesting the same patient. Is. In addition, JP-A-5-151282
In the “Clinical test system” disclosed in the publication, as in the above, the previous test results are stored for each patient and compared with the current test result value to quickly obtain highly reliable test results. It is provided.

[0004]

In any of the above-mentioned conventional techniques, the previous (one time before) inspection result value is referred to,
The accuracy of this inspection result has been improved. By the way, as a recent tendency, it is often found that the inspection result values have a correlation between the inspection items, and it is not enough to simply compare the latest inspection history value with the current inspection history value. It has become enough. Further, by using this relationship, it is possible to further increase the reliability of the inspection result. But,
In the above-mentioned prior art, such consideration was not given. For example, by comparing inspection history values between inspection items,
As shown in FIG.
In the above example, "result A" and "result B" or "result D" and "result B" are required as the latest inspection history values. However, in the above-mentioned conventional technique, such a point is taken into consideration. Didn't. Further, the above-mentioned conventional technique has a problem that it is not possible to deal with the change of the inspection method for each inspection item. That is, in the conventional technology, each time the inspection method is changed, the attribute information such as the abbreviation of the inspection item, the normal value, the position of the decimal point, and the unit is always updated to the latest state. When providing, the attribute at the time of the inspection needs to be displayed, but all the inspection history values are made to correspond to the updated latest attribute. This means that the accumulated inspection history values cannot be fully utilized. The present invention has been made in view of the above circumstances, and an object of the present invention is to meet various reference requests in order to solve the above-mentioned problems in the conventional technique and improve the inspection accuracy in a clinical laboratory. It is possible to manage the inspection history value with an appropriate attribute,
An object of the present invention is to provide an inspection history filing system capable of flexibly coping with a change in inspection method.

Further, reference numeral 210 is a report output step for outputting the test result value for each patient and a comment for the test result value. The detailed operation of the examination history filing system according to the present embodiment will be described below by taking the examination history acquisition for the patient illustrated in FIG. 11 as an example. (1) In the case of the method in which the uninspected is regarded as the inspection result regardless of the inspection request of the pattern 1 and the inspection result of the previous time is used as the inspection history value: First, it is acquired from the date table of FIG. The reception date of the previous inspection request and the inspection item codes 2001 and 2002 of the patient in the inspection history file of FIG.
Compare the date when the inspection request was received one time before.

In this case, since the inspection item code 2001 and the inspection item code 2001 are the same, the "result D" is the inspection history value, and the inspection item code 2001 is not the same, so "(uninspected)". Is the inspection history value.
Next, the attribute data is selected as follows. 1 of inspection item code 2001 obtained from the inspection history file of FIG.
The previous inspection execution date and the change date of the inspection item code 2001 in the item history file of FIG. 7 are sequentially compared. In this case, the last change date is before the inspection date, so
The attribute in the item master of FIG. 4 corresponds. Needless to say, when the previous change date is after the inspection execution date, the attribute data of the change date immediately before the inspection execution date in the item history file of FIG. 7 corresponds.

(2) Regardless of the date when the inspection request is received in Pattern 2, the method in which the uninspected result is not treated as the inspection result and the immediately preceding inspection result is used as the inspection history value: In the inspection history file of FIG. “Result D” and “Result B”, which are the test results of the test item codes 2001 and 2002 of the patient one time before, are the test history values. At that time, for “Result D” and “Result B”,
The same attribute data selection processing as in item (1) is performed. (3) In the case of performing an inspection history value search for multiple inspection items in pattern 3, when the inspection result of the latest inspection request acceptance date for which all specified inspection items have been inspected is used as the inspection history value : In the examination history file of FIG. 8, the examination request acceptance dates of the examination item codes 2001 and 2002 of the patient from one time before are compared, and when there is a coincident date,
Here, "result A" and "result B" are inspection history values. At that time, the attribute data selection process similar to that of the item (1) is performed on the “result A” and the “result B”.

(4) In the case of the method of using the inspection result of the latest acceptance date of the inspection request for which all the correlated inspection items are requested to be inspected in the pattern 4, the related item definition file of FIG. From the inspection item code 2001, 20
Get the related item code of 02. Then, in the examination history file of FIG. 8, the examination item code 2001 of the patient concerned
The inspection request acceptance dates from before 2002 and 3001 are compared, and if there is a matching date, "result A", "result B", and "result C" are the inspection history values here.
At that time, the attribute data selection process similar to the item (1) is performed on the “result A”, “result B”, and “result C”.

(5) In the case of the pattern 5 in which all the inspection results on the specific inspection request acceptance date are used as the inspection history values:
From the date table of FIG. 6, in which the designated date of the examination history value search of the patient is stored in the examination request acceptance date, the smallest examination item code 200 of the examination item codes of that day is stored.
Get 1. Then, in the examination history file of FIG. 8, the “result A” in which the examination request acceptance date of the examination item code 2001 of the patient matches the designated date, and the next largest examination item code 2002 of the patient are acquired. Next, also in FIG.
Test history code of the patient in the test history file
"Result B" when the inspection request acceptance date of 02 matches the specified date
Then, the next largest inspection item code 3001 is acquired.

Further, in the inspection history file of FIG.
The "result C" in which the inspection request reception date of the inspection item code 3001 of the patient matches the designated date is acquired. that time,
For the "result A", "result B", and "result C", the same attribute data selection process as in item (1) is performed. According to the present embodiment, firstly, by providing an inspection history file for each patient and each inspection item and a related item definition file for each inspection item, the inspection history information is managed by using these files It becomes possible to provide the inspection history value in a plurality of patterns.

Secondly, by providing an item history file for each inspection item, even when the inspection method is changed, the change date, the abbreviation of the inspection item before the change, the normal value, the decimal point position, the unit, etc. By holding it, it becomes possible to provide the attribute at each inspection point at the same time when the inspection history value is provided. It is needless to say that the above embodiment shows one example of the present invention, and the present invention should not be limited to this. For example, the configurations of the files, tables, and the like shown in the embodiments are appropriately modified and combined, for example.
