Abstract:
Objective To establish a set of automatic audit rules for clinical chemistry test results, and use computer system to realize automatic audit and confirmation of test results.
Methods The study followed the requirements of the Clinical and Laboratory Standards Institute(CLSI) AUTO10-A and combined the basic data of patients, medical decision levels, methodological performance, relationship between the test items, and quality control level of the laboratory. The autoverification rules of clinical chemistry was formulated and the test results were automatically auditted by the middleware system of DM2 (Data Manager 2).
Results We have established 540 autoverification rules for 53 biochemical test items. 285 415 tests have been conducted on 16 593 routine chemical samples. The results showed that 14 289 samples have passed the automatically audit, accounting for 97% of outpatient samples, 80% of inpatient samples, and 86% of the total. The reported turnaround time (TAT) decreased from 183 minutes to 131 minutes, which was 28.4% less.
Conclusion Formulating reasonable and effective clinical chemical autoverification rules and using the automatic audit function of DM2 can fully utilize the efficiency of automated assembly line, shorten TAT and improve the post-analytical quality control.
