Development and implementation of an LIS-based validation system for autoverification toward zero defects in the automated reporting of laboratory test results

Table 4 Comparison of the time consumption (hours) of the two methods for verifying HBV reports for 3000 cases

Steps	Manual validation (h)	New method (h)
1. Set 65 rules	1.5	1.5
2. Perform Rule 130 test	2.5	2.5
3. Correctness verification	0	0.25^a
4. Personnel comparison report and results review	240	240
5. Record comparison result	100	0^b
6. Analysis of the verification number	10	0^b
7. Determine whether to activate automatic approval	5	0^b
8. Personnel analysis of the reasons for inconsistent audit results	90	30
9. Add and modify rules	1	1
10. Determine whether to turn off autoverification	1	0^c
Total	452	275

In the measurement of the validation time, we divided the complete autoverification into 10 stages. The statistics of manual verification and the new method for each step are shown in Table 4. In steps 4–6, in total, 3000 reports are used for statistics. The time consumption of the consistent work content in the new and old methods is subject to the following: the manual timing of the old method, such as steps 1, 2, 4, and 9; the inconsistent steps in the two methods; the new steps that are recorded in the system, such as step 3; the saving step time clearing, such as steps 5, 6, 7, and 10; and the remaining steps that are estimated, such as step 8
For automatic implementation, the time is calculated as zero
