Abstract:ObjectiveTo observe the effect of the application of PDCA cycle in the sample management of schistosomiasis laboratory.MethodsThe information of unqualified samples in schistosomiasis immunization laboratory from June 2014 to May 2015 was collected,and according to the reasons of the non-qualification of samples,cyclic intervention measures were carried out on each section in the communication with the subjects before sampling,sampling collection, information labeling,storage and transportation as well as sample reception with the PDCA cycle theory from June 2015 to May 2016;information of the unqualified samples after the implementation of PDCA cycle was observed and compare with the data of the unqualified samples before implementation.ResultsBefore the implementation of the PDCA cycle from June 2014 to May 2015,there were altogether 11 227 immunodetection blood samples receiving by the laboratory. Among all the samples,there were ipo-turbid,hemolysis,small amount of samples,misuse of anticoagulant tube,non-prompt serum separation,sample contamination and deterioration,unclear information identification of samples,wrong information identification,missing identification information and duplicate identification information unqualified samples of 95;after the implementation of PDCA cycle from June 2015 to May 2016,there were altogether 11 742 immunodetection blood samples receiving by the laboratory,including 51 unqualified samples,and the rate of unqualified samples of each type had the reducing tendency compared with the rate before the implementation,with an average decrease rate of 49.41%. Before the implementation of PDCA cycle,the number of the unqualified samples in the laboratory accounted for 0.85% of the total number of the samples;and after it,the number of the unqualified samples in the laboratory accounted for 0.43%of the total number.Through the comparison between them,the difference was highly significant(χ2=15.25,P<0.01).ConclusionThe introduction of PDCA cycle management samples into the schistosomiasis diagnosis laboratory has effectivelycontrolledtheoccurrenceofunqualifiedsamples and significantly improved the sample quality management.
