目的评价河北省痰抗酸杆菌涂片检查室间质量控制实施效果。方法采用双盲法进行室间质控,萋-尼氏抗酸染色法;分析2006～2008年痰抗酸杆菌涂片检查室间质量控制报表。结果室间质控中镜检第一复检结果准确度较高;各级实验室痰涂片制片质量逐年提高;2006～2008年度涂阳肺结核病检出率保持在较高水平。结论双盲法室间质量控制,激发了基层实验室技术人员参与竞争意识,提高了室间质控的透明度和公正性,提高了全省痰检实验室的整体水平,从而提高了全省涂阳肺结核病人发现率。
Objective To evaluate the effect of sputum acid-fast bacillus smear test in Hebei Province on the quality control of inter-laboratory. Methods The double-blind method was used to control the quality of the room, and the 萋-Nessler acid-fast staining method was used. The quality control reports of sputum acid-fast bacilli smear examination between 2006 and 2008 were analyzed. Results The accuracy of the first re-examination was higher in the inter-laboratory quality control examination. The quality of the sputum smear preparation at all levels increased year by year. The detection rate of smear-positive pulmonary tuberculosis in 2006 ~ 2008 was kept at a high level. Conclusion The double-blind method of inter-room quality control has stimulated the participation of grass-roots laboratory technicians in competition awareness, improved the transparency and fairness of laboratory quality control and raised the overall level of sputum testing laboratories in the province, Positive rate of pulmonary TB found.
