Building and Validating an Autoverification System in the Clinical Chemistry Laboratory

Objective: In this study we give a detailed description of how to construct verification rules and then evaluate the benefits brought to the laboratory. Methods: All logic processes and verification rules are constructed in middleware with reference to the CLSI Auto10-A Guideline. There were 569,001 patient test results collected to establish the range of the limit check, delta check, and the consistence rule check. Results: Daily results show the autoverification (AV) passing rate of all test results to be 92%similar to 95%. About 80% of test reports can be auto-released. Conclusions: Individual differences in the verification of test results are eliminated, turnaround time (TAT) is shortened, and full-time equivalent (FTE) are reduced, thus enabling medical technologists to devote more time and effort to handling intercepted test reports, which, in turn, improves the quality of patient care.
