Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a system in which test processing is independently executed by an automatic analyzer in response to a large number of computer-managed test requests such as clinical tests. The present invention relates to an inspection data output processing system for correctly associating inspection results with each inspection request.

[Technical background] Hospitals and other medical institutions issue test requests specifying multiple different test items for blood, urine, and other samples from a large number of patients, and when the test results are obtained, they are tested. A clinical testing system is used that responds to the requester.

In such a system, extremely high reliability is required because any error in the correspondence between patients, specimens, and their test results may lead to serious consequences.
FIG. 1 is an explanatory diagram of an example of a general clinical testing system, in which 1 is a host computer of the clinical testing system, 2
3 is client work in the medical department, etc., 3 is reception work in the testing department,
4 represents reception input processing, 5 represents inspection processing, 6 represents report output processing regarding test results, and 7 represents other management data output processing.

・In request source task 2, a request form is created for each patient's specimen.

The request form includes items such as patient number, name, department, and hospitalization/external admission. In the reception task 3 of the testing department, a reception number is assigned to the received request form, and the requests are sorted into blood test, urine test, and other various testing departments. Note that the reception number is a sequential number. In reception input processing 4, the data of a large number of received request forms is input from the terminal to the host computer 1, a worksheet is created that instructs the work procedure for each testing method such as testing equipment, each specimen is classified, and the work sheet is Organize by sheet.

FIG. 2 is an example of such a worksheet, which is a work instruction table for a sample group on which a blood biochemical test is to be performed. In the figure, SEQ is the work order number for measuring the specimen, and the columns 1 to 20 following the reception number are for specifying the analysis items to be performed for each specimen.
Returning to FIG. 1 again, in test processing 5, samples are analyzed sequentially for each of the created analyzer-specific worksheets or manual worksheets for those analyzed without using an instrument, and the results are hosted. Transfer to computer. In the case of using an automatic analyzer, the test results are transferred and processed through a data collection device, and in the case of manual analysis, the test results are entered via a keyboard. The host computer matches the transferred test results with the request form data and performs the process of outputting the patient-specific report in step 6. Also, periodically prepare various statistics, daily reports, monthly reports, etc. The report created in this way is sent to the requester. In such a clinical testing system, test results obtained sequentially are assigned to the work order number of the worksheet (SEQ in Figure 2).
) must be correctly mapped.

However, a normal automatic analyzer has the ability to continuously automatically analyze, for example, about 300 samples loaded at once, but inside the automatic analyzer, the sample order is independent of the work order number. A number is generated to manage the analysis results. Therefore, in the data collection device, it is necessary to perform a process of associating the sample sequence number outputted with the test results from the automatic analyzer with the work sequence number, organize the test results by the work sequence number, and transfer them to the host computer 1. . However, in actual test processing using an automatic analyzer, there are cases where the work order number does not line up with the sample order number during the execution process due to the following circumstances.

1. In order to control the measurement accuracy of an automatic analyzer, it is necessary to insert samples whose analysis values are known in advance into a sample array for each fixed number of samples or according to specified conditions, and then measure them. .

2. Samples with the same reception number may be retested.

3. The sample may be damaged and cannot be measured.

4. Workers may mix up and arrange samples.

Previously, when there was a change in the sample arrangement, it was necessary to reset the correspondence data covering the entire number range in order to correct the correspondence between the work order number and the sample order number. In this method, it is necessary to input both the work order number and the sample order number, which is complicated, and there is a possibility that an error may occur during the input operation. [Object and Structure of the Invention] An object of the present invention is to provide a control means that makes it possible to perform a process of correcting the correspondence between a work sequence number and a specimen number more easily than before. The configuration is to assign a series of work order numbers to multiple analysis requests, and to assign a series of sample order numbers to multiple samples to be analyzed, perform continuous automatic analysis, and assign each sample order number. In a clinical testing system that retrieves analysis results according to a sequence number and reports them in correspondence with a work sequence number, there is provided a work order management table means for managing the arrangement of work sequence numbers, and a sample order management table means for managing the arrangement of sample sequence numbers. and data collection processing means for basically associating work sequence numbers and sample sequence numbers according to their respective arrangement orders based on the work order management table means and the sample order management table means, and the work order management table means includes control information for invalidating a specified work order number and control information for specifying a sample order number at a position that does not follow the sequence order, and the sample order management table means includes control information for invalidating a specified work order number and control information for specifying a sample order number at a position that does not follow the sequence order, and the sample order management table means It is characterized by control information for distinguishing whether it is a specimen or a management specimen for checking analysis accuracy, etc., and a specimen order number at a position that does not follow the above arrangement order.

[Embodiments of the invention]

The details of the present invention will be explained below based on examples.

FIG. 3 is a schematic configuration diagram of an apparatus according to an embodiment of the present invention.
In the figure, 1 is a host computer, 10 is a terminal device, 11 is a sample row, 12 is an automatic analyzer, 13 is a data collection device, 14 is a data collection processing unit, 15 is a work order management table, and 16 is a sample order management table. A table 17 is an example of output data and indicates work order data. The sample array 11 is composed of, for example, several tens to hundreds of patient blood samples and a plurality of quality control samples inserted according to a certain standard.

In the figure, u represents a patient sample and p represents a quality control sample. The quality control sample p can include a plurality of different types of samples in order to check a plurality of points within each measurement range of the automatic analyzer. Such a sample array 11 is loaded into an automatic analyzer 12.

The automatic analyzer 12 automatically analyzes each specimen and quality control sample in sequence, and outputs the results to the data collection device 13. The data collection processing unit 14 of the data collection device 13 has a work order management table 15 for managing the sample analysis work instructed in the worksheet explained in FIG. Process each control, management information, and analysis result data with the sample order management table 16 for managing them by sample order number, and create work order data by comparing the analysis result data of the samples corresponding to the work order number. and output to the host computer.

The work order management table 15 includes columns such as work order number, reception number, pass flag, and sample order number pointer.

■ The work sequence number and reception number correspond to the worksheet and are the keys when reporting the results to the requester.

(2) The pass flag is used as control information to invalidate the work order number by setting a flag "B", for example, when a sample with a certain work order number becomes unanalyzable due to damage or the like. In this case, the corresponding analyte is not present in the autoanalyzer. @ In the sample sequence number pointer column,
When re-analyzing a sample with the same work order number several times, the sample order number is displayed to specify one analysis result to be adopted.

The sample order management table 16 includes columns such as sample order number, sample type, forced point flag, and data.

(2) The sample order number is a number for managing each sample in the sample array 11 loaded into the automatic analyzer 12 and quality control samples, and is given in an order.

(2) Specimen type is control information that includes, in addition to the aforementioned sample u and quality control sample p, a sample order number or a flag D (dummy) for invalidating the analysis result data.

◎' Forced point flag is for marking the sample sequence number pointed to by the sample sequence number pointer of the work order management table 15, and is assigned the symbol *.

2' data is analysis result data output from the automatic analyzer 12 together with the sample order number.

The work order output data 17 is created from the work order management table 15 and the sample order number table 16, and includes the work order number,
Consists of reception number, data, etc.

Next, the processing performed by the data collection processing section 14 of the embodiment apparatus shown in FIG. 3 will be explained using several specific examples.

{1 When the quality control sample is not included in the sample row 11 and no other exception processing is involved As illustrated in FIG. Make a one-to-one correspondence from the beginning.

Both numbers do not need to match; processing is performed based on only the order. {2} When a quality control sample is included between the sample rows 11, as illustrated in FIG. The sample order numbers with only u are associated with the work order numbers in order from the beginning.

When a sample with the same glue reception number is analyzed twice (retesting) As illustrated in FIG. 6, the data of sample order number 4 is assumed to be the retested data of sample order number 2.

At this time, the following processing is performed. ■ Sample order number 4 is
Indicates that it is the result of work order number 2.

■ The result of sample sequence number 2 originally corresponds to work sequence number 2, but since it was instructed to correspond to the result of sample sequence number 4, the result of sample sequence number 2 was artificially changed (specimen type was changed to managed sample). P
or set to dummy 0) or automatically removed from the target of response.

■ Set 4 to the sample order number pointer of work order number 2 in the work order management table. ■ Associate the work order management table and sample order management table from the beginning.

If a number is included in the sample sequence number pointer in the work order management table, it is associated with the result data of the corresponding sample sequence number. Conversely, if "*" is included in the forced point flag in the sample order management table, the work order management table containing that sample order number is searched and associated. In addition, the solid line arrow in the figure represents the above-mentioned process, and the dotted line represents the process when there is no indication of the sample order number pointer and no display of the forced point flag.

[4- When changing the sample type As illustrated in Figure 7, for example, if a setting error is discovered and the sample type of sample order number 2 is changed from u to P,
The correspondence between work order number 2 and sample order number 2 is sample order number 5.
The correspondence between the numbers is changed from the dotted line to the solid line as shown in the figure.

'5} When correcting a sample mix-up, as shown in Figure 8, set "*" to the forced point flag for the corresponding sample order numbers 1 and 5 in the sample order management table. Then, the sample sequence number pointer 5 is set to the work order number 1 of the work order management table, and the sample sequence number pointer 3 is set to the work order number 3.

In this case, the sample order number array is associated with the work order number array after hitting from the beginning, and only the sample order numbers 1 and 5 with forced point flags of “*”, as shown by the solid arrows in the figure, are Work order number 3 including the order number as a pointer
, 1. '6} When the specimen is damaged As illustrated in FIG. 9, when the specimen with reception number 3 is damaged, the pass flag of work order number 3 in the work order management table is set to "B".

As a result, in the process of associating the sample order number array with the work order number array, work order number 3 is passed, and the next work order number 4 is associated as shown by the solid arrow in the figure. Next, FIG. 10 shows a flowchart of an algorithm for processing by the data collection processing unit that associates the above-described work order management table with the sample order management table.

In the figure, the number of entries in the sample order management table is M, the number of entries in the work order management table is N, and the first work order number is j.
o, shows a processing example when the first sample order number is P. Generally M>N, and the difference corresponds to the total number of quality control samples or dummies. The entries with sample order number i in the sample order management table are sequentially checked, and each entry is associated with one of the entries with work order number i in the work order management table, and the process ends at j=P+(M-1). . Similarly, it is also possible to sequentially check the work order numbers i in the work order management table and associate them with the sample order numbers j in the sample order management table, and an example of the processing flow is shown in FIG. Next, a method of inputting corrections in the case of sample retesting or sample mix-up in the present invention will be explained. For example, in the case of the reexamination shown in FIG. 6, in the conventional system, it was necessary to input the following instructions regarding the correspondence between the work order number and the sample order number.

In contrast, in the method of the present invention, it is only necessary to set the sample sequence number pointer and forced point flag of the relevant entry.

For example, call up the work order management table and the sample order management table on the display screen of the terminal device, and use the cursor operation to move the sample order number pointer of work order number 2 to 4.
Enter “*” in the forced pointer flag of sample order number 4.
It is sufficient to input , and there is no need to instruct the correspondence over the entire number range as in the conventional system. Similarly, no matter how complex the problem is, such as correcting sample damage or failure, or changing the sample type, you can use the work order management table and sample order management table pass flags, sample order number pointer, sample type, etc. on the display screen. The purpose can be easily achieved by simply setting or updating the forced point flag or other relevant items to desired values.

In addition, in order to reflect the quality control on the analysis results, a sample type column is introduced in the work order management table as shown in Figure 11, and the insertion status of the quality control sample or the analysis result data can be output and displayed. I can do it.

〔Effect of the invention〕

As described above, according to the present invention, the correspondence between the work order number or reception number and the sample order number can be easily and reliably corrected in response to a change in the set analysis order of the sample, or a change in the situation such as damage. The reliability and operability of the clinical results system can be improved.
