- Abstract
Objective: Errors in pre-analytical phase decrease the accuracy of reports from clinical laboratory department. Considering the disqualified rate of pre-analytical sample in our hospital, we performed several intervention measures to improve the situation. Design: The disqualification rate in the pre-analytical phase was obtained before and after multiple intervention measures to evaluate the effects. Methods: The disqualified sample types and major causes of errors in the pre-analytical phase were investigated in clinical laboratory department from Sept. 2008 to Aug. 2009. In the following year, we utilized multiple measures to properly intervene the key points of whole sample collection process, and the pre-analytical errors were reanalyzed tri-monthly, then the disqualification rate of total, major disqualified sample types and different test groups were calculated to evaluate the effects of the intervention measures. Results: The total disqualification rate in the pre-analytical phase obtained from Sept 2008 to Aug 2009 was 1.36%, and the major types of disqualified samples were coagulation of anticoagulant sample, sample inadequacy, sample container error, sample information error and sample type error. After one year intervention through key points of whole pre-analytical sample collection process, the total disqualification rate dropped to 0.94%, and the disqualification rate of coagulation of anticoagulant sample, sample inadequacy, sample container error, sample information error and sample type error decreased by 20.45%, 28.00%, 25.00%, 76.92%, and 66.66% respectively. As for test groups, the decreasing amplitude of biochemical, routine, immunological, microbiological and emergency test group was 47.36%, 33.33%, 20.00%, 50.00% and 21.43% respectively. Conclusion: The overall effect of the interventions is very good, and the disqualification rate of the main causes decreases to various degrees.
