To explore the effect of Pareto analysis on the investigation of DR (Digital Radiography) high fault rate.
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.
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%.
Pareto analysis is effective in reducing DR fault rate and is worthy of being promoted to other medical devices.
探讨帕累托分析在数字X线摄影（DR）高故障率调查中的作用。
成立质量控制小组，利用我院8台DR近3年的故障统计分析DR高故障率的原因，制定并实施对策，然后与整改后的数据进行比较。
实施3个月后，我院DR故障次数从每季度130次降至每季度47次，同比下降63.8%。其中，控制台故障次数从每季度105次降至每季度25次，同比下降76.2%，接近80%。
帕累托分析在降低DR故障率方面有效，值得推广至其他医疗设备。
