Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing system that uses inspection data in a plurality of inspection institutions and hospitals.

[0002]

2. Description of the Related Art Conventionally, a disc shape has been used as a medium for recording information using light and reading the recorded information.
Various types such as cards and tapes are known. Among them, the optical information recording medium formed in a card shape (hereinafter referred to as “optical card”) is expected to be in great demand as a write-once information recording medium having a large recording capacity which is small, lightweight and convenient to carry. There is. In the medical field, in particular, the patient holds an optical card on which a medical record, test information, etc. are recorded, whereby data such as blood test data and test result data for each predetermined period, type of medication, medication period, etc., or It is drawing attention as being able to avoid double medication and double examinations by sharing patient information between different hospitals and laboratories.

Therefore, in order to make the inspection data recorded on the optical card easy to see, a method of displaying the inspection data on a computer screen is disclosed in JP-A-6-20116 and JP-A-6-4.
No. 3836 is proposed. These conventional examples will be briefly described below. First, according to JP-A-6-20116, in an information card system having an information card, an information card data recording and / or reproducing device, an information processing device and a data display device, data is recorded in chronological order. The data string is displayed as a graph, and the data is normalized by the maximum value and / or the minimum value in the data string to determine the upper limit and / or the lower limit of the graph display. In this way, when the numerical data is displayed as a graph, the data value of each measurement point is displayed regardless of the range of the numerical value of the data, so that the numerical display of the data can be easily viewed.

According to Japanese Patent Laid-Open No. 6-43836, reproducing means for reproducing information recorded on an information recording medium, selecting means for selecting an item to be displayed from the information by the reproducing means, and First display means for displaying the data of the item selected by the selecting means in a time series on a table, and second display means for displaying the numerical data of the item selected by the means in a time series on a graph An information display device is provided. In this way, when the inspection data of the selected item is numerical data, the carrying of the time-series changes can be easily viewed from the graph, and detailed numerical values and inspection items that cannot be graphed can be displayed at the same time without switching the screen. As you can see, it has the effect of making it possible to perform comprehensive checks on a single screen.

In addition, for one year of the patient shown in FIG.
The example which made the table and the graph the change of the measured value of total cholesterol (CHOL) of the time) is shown. FIG. 1A is a table showing the inspection month, the inspection organizations A and B, and the measured CHOL value. In this examination, the examination is carried out at two places of the examination institutes A and B according to the convenience of the patient, and the resulting numerical data is recorded on the portable optical card carried by the patient. The patient carries this optical card with each examination, and serves for medical examination and medication treatment.

Next, a line graph of the inspection data is shown in FIG. 1B. From this line graph, it can be diagnosed to some extent that the total cholesterol (CHOL) value of this patient is improving, and medical treatment such as reducing the dosage is performed.

[0007]

However, when the inspection institutions used differ among hospitals or each inspection institution, the range of reference values of inspection data also differs. Therefore, when the data recorded by different hospitals / laboratory organizations are displayed on the same graph, there is a problem that it is difficult to judge the tendency of the symptom of the patient. In particular, in April of FIG. 1B, there is data of the inspection body B around March and May, and it is difficult to grasp the inspection tendency due to the variation of the inspection organization, which may cause the doctor to be confused about the treatment method. . Further, according to the examples of the prior publications, there is no involvement in the variation of the inspection organization and the inspection numerical value normalization is not performed, and it is difficult to grasp the tendency of symptoms similar to the above. This problem is not limited to the examination of the medical condition, and the same problem occurs in other time-series data acquisition. For example, when different measuring devices are used in the performance test of the device, there is a problem in that the data is different each time the measurement is made due to the variation between the measuring devices and the error of the normality judgment of the device is apt to occur.

[0008]

Means (and Action) for Solving the Problems
In an information processing system including means for recording inspection data on an information recording medium and means for reproducing inspection data, a means for recording a reference value together with the inspection data and a reference value for the inspection data in order to solve the above problems. There is provided an information processing system including means for normalizing the normalized value and means for displaying the normalized value in a time series graph. This information recording medium uses an optical card that is convenient to carry, records inspection data that changes from time to time, and records, for example, maximum and minimum values due to variations in inspection data as reference values. By normalizing the inspection data and suppressing the variation of the data and displaying the data in the form of a graph, the tendency of the inspection data can be accurately grasped, and a data judgment error can be prevented. In particular, since the examination data of a patient is related to human life, the information processing system according to the present invention is extremely important.

【Example】

First Embodiment Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 4 shows a schematic diagram of an information processing system used in this embodiment.

In FIG. 4, reference numeral 1 denotes a personal computer of an information processing apparatus, which is an arithmetic processing unit for actually performing information processing, a keyboard 3 for inputting data input instructions and display instructions, and a display device for displaying data. It is composed of the display 4. The personal computer 1 is generally a distributed type, but may be a central management type host computer as long as it is provided with arithmetic processing, recording, and input / output devices. Also,
Reference numeral 2 denotes an optical card recording / reproducing apparatus for recording / reproducing on / from an optical card of an information recording medium, which is connected to the personal computer 1 by an interface SCSI. This information processing system is installed in each inspection institution such as a hospital or clinic, and inputs the inspection result of the patient from the keyboard 3 or is connected to an external inspection device and inspection data of the inspection result from the external inspection device. To the connector RS-232C, and the optical card recording / reproducing device 2
To record. This optical card is generally a write-once type recording medium, but it may be a rewritable type and may be recorded by using an IC card recording / reproducing device when carrying an IC card. At this time, the maximum value and the minimum value are recorded as the reference value of each inspection item together with the inspection data.

FIG. 2 shows a data table for each month of one year of CHOL (total cholesterol value) recorded by the inspection institution A and the inspection institution B recorded on the optical card of a patient. The test data is that of the patient used in the conventional example. MAX,
The MIN is the maximum value and the minimum value as the reference value by the inspection equipment of each inspection organization. The maximum value and the minimum value are obtained by measuring the CHOLs of a plurality of persons with the inspection device of the inspection organization and obtaining the maximum value and the minimum value as reference values from the measured data. However, the data that is apparently a measurement error is deleted. This is because the inspection data including the maximum value or the minimum value is recorded on someone's optical card, so extremely different data such as a recording error or inspection error is removed when recording on the optical card. It can be said that the minimum value is the normally measured inspection data. Since it is recorded on the optical card at the time of inspection at each inspection institution, it can be recognized even in hospitals at different locations. The numbers in the rightmost column in Figure 2 are
When this patient receives a medical examination at a hospital, reproduces test data and reference values in the information processing system of the present invention,
It is a normalized value.

The normalization method used in this embodiment is represented by the following equation, where X is the inspection data and Y is the normalized value. Y = (X- (MAX + MIN) / 2) / (MAX-MIN) (1) where MAX is the maximum value and MIN is the minimum value. For example, in May, Y = (262.440- (240 + 130) / 2) ÷ (240-130) = 0.704.

In this case, the reference value in the normalized value is in the range of 0.5 to -0.5. FIG. 3 is a time-series line graph of normalized values from the data table of FIG. The graph in FIG. 3 is obtained from the same test data values as in FIG. 1B, and the variation between the inspection institutions A and B is suppressed, and from the graph in FIG. 3, the CHOL of this patient follows the month. It has been improved in each case,
Not only the patient himself, but the doctor can judge the medical examination accurately,
Dosing instructions are also likely to be accurate.

In the above-mentioned embodiment, an example of preventing the variation due to the inspection organization of the hospital is shown, but the variation is not limited to the medical field but the variation of the measuring device causes the object to be inspected to change in time series or the object. It can also be applied to the field related to the case where the inspection object changes depending on the place, temperature, etc.

Further, the standard values to be normalized are the maximum value and the minimum value, and are normalized by the above mathematical expression (1). However, the standard values may be other numerical values such as standard deviation and average value. Alternatively, the normalization may be performed using a mathematical expression other than the mathematical expression (1). Although the data recorded on the information recording medium is the inspection data and the reference value, the effect of the present invention can be obtained even if the reference value is a normalized value.

Further, in the above embodiment, the optical card is used as the information recording medium, but other various types such as a disc shape, a card shape and a tape shape may be used, and the information recording apparatus is adapted according to the medium, It is possible to improve the reliability of the data regarding the variation of the measuring device.

[0017]

As described above, it is possible to normalize the inspection data by recording the inspection data and the reference value on the optical card, it is possible to suppress the variation of the inspection device, and the inspection is performed by a plurality of inspection institutions. Even if this is done, the inspection data can be graphed without error, and the tendency of the patient's medical condition can be accurately grasped.
