Application of Pareto Analysis in Studying DR High Fault Rate / 中国医疗器械杂志

ABSTRACT

OBJECTIVE@#To explore the effect of Pareto analysis on the investigation of DR (Digital Radiography) high fault rate.@*METHODS@#The quality control team was established to analyze the causes of DR high fault rate by using the fault statistics of eight DR in our hospital for nearly three years,and to formulate and implement countermeasures,then compare them with the data after rectification.@*RESULTS@#After three months of implementation,the number of DR faults in our hospital decreased from 130 times/quarter to 47 times/quarter,a year-on-year drop was 63.8%.Among them,the number of console faults decreased from 105 times/quarter to 25 times/quarter,a year-on-year drop was 76.2%,close to 80%.@*CONCLUSIONS@#Pareto analysis is effective in reducing DR fault rate and is worthy of being promoted to other medical devices.
