Status analysis of 15 quality indicators at clinical laboratorieis of 8029 medical institutions in China / 中华医院管理杂志

ABSTRACT

Objective To investigate the 15 quality indicators at medical institutions in China , and to explore the model of quality specifications .Methods Online questionnaires were sent to 8029 clinical laboratories ,with the results analyzed by SPSS 20 .The 25th percentile ,50th percentile ,and 75th percentile of the distribution ,according to the level of the hospital ,were regarded as the optimum , appropriate and minimum quality specifications for each quality indicator ,respectively .Results As shown in the median ,sigma values of most indicators were greater than 3 .The defect percentages of test uncovered by internal quality control (IQC)and test uncovered by inter-laboratory comparison were 47.46％ and 85.73％ ,respectively ,both too poor to calculate the sigma values. The turnaround time (TAT )differed greatly among the subjects.The longest time of pre-examination TAt and Intra-laboratory TAT were clinical immunity. The minimum quality specifications for the quality indicators were from 3σ to 6σ.Conclusions Laboratories should strengthen their IQc and inter-laboratory comparison with continuing education training to realize the continuous quality improvement .
