肺结核病人痰涂片镜检不同质控方式效果评价

目的 探讨适合我国各级实验室开展的痰涂片室间质量控制模式?方法 设计了在不同地理条件下应用不同督导方式进行痰涂片镜检室间质控?结果及结论 经培训后直接督导和间接督导之间?山区和平原之间复检痰片的各项符合率均无统计学差异?直接督导费用明显高于间接督导;山区督导费用明显高于平原(P<0.05)?结合二种督导方式在各自实施中的特点,认为培训和室间质控是提高痰检质量的必要手段,在我国现阶段可根据各地区的疫情?结防力量?痰检水平和经费等实际情况,采取两种督导方式相结合?偏重其中一种模式进行痰涂片镜检质量控制?

Evaluation of quality control system for sputum smear microscopic examination in tuberculosis diagnosis

Objective To establish and develop a feasible Quality Control(QC)system for sputum smear microscopic examination in China.Method Four times external QC were carried out by way of direct supervision and indirect supervision in plain area or mountain area laboratories within one year.Results and Conclusion The accordance rate of QC between direct and indirect supervision did not show significant difference.The substance of direct supervision is much richer and the cost is much lower than that of direct supervision.Based on the results of the study,we suggest direct supervision is very effective and can not be replaced by other method,especially at the beginning of QC.Local laboratories can combine the two supervision methods according to their own economical and topographic condition,but they must perform direct supervision at least once a year.
