Abstract
Objective: To apply and verify the application of intelligent audit rules for urine analysis by Cui et al. Method: A total of 1139 urine samples of hospitalized patients in Tai’an Central Hospital from September 2021 to November 2021 were randomly selected, and all samples were manually microscopic examined after the detection of the UN9000 urine analysis line. The intelligent audit rules (including the microscopic review rules and manual verification rules) were validated based on the manual microscopic examination and manual audit, and the rules were adjusted to apply to our laboratory. The laboratory turnaround time (TAT) before and after the application of intelligent audit rules was compared. Result: The microscopic review rate of intelligent rules was 25.63% (292/1139), the true positive rate, false positive rate, true negative rate, and false negative rate were 27.66% (315/1139), 6.49% (74/1139), 62.34% (710/1139) and 3.51% (40/1139), respectively. The approval consistency rate of manual verification rules was 84.92% (727/856), the approval inconsistency rate was 0% (0/856), the interception consistency rate was 12.61% (108/856), and the interception inconsistency rate was 0% (0/856). Conclusion: The intelligence audit rules for urine analysis by Cui et al. have good clinical applicability in our laboratory.
