目的利用Access对2004-2013年东乌珠穆沁旗结核杆菌痰涂片镜检结果进行统计分析,探讨其样本性状、采样时间等各种因素与结核杆菌检出率的关系和影响,以及本地区结核病控制的效果。方法利用Microsoft Office Access建立结核杆菌痰涂片结果数据库及利用图表对镜检结果进行统计分析。结果痰涂片总数在2008年达到最高峰后,呈逐年下降趋势,痰涂片阳性率也呈逐年下降趋势;即时痰的涂阳率最高为15.83%,夜间痰涂阳率为14.65%,晨痰涂阳率为13.52%;晨痰的标本合格率最高为59.53%、即时痰为58.57%、夜间痰为50.67%;干酪样痰的阳性率最高为37.12%,血样痰为23.74%,粘液痰为14.74%,唾液痰为2.80%;结论本地区在DOTS策略下传染性结核病得到了有效控制。统计分析得出采集的痰标本质量、检验人员的制片和读片质量都是影响结核杆菌痰涂片阳性检出率的重要因素,应指导病人掌握咳痰的方法等来提高痰标本的质量,加强对实验室检验人员的建设和质量控制,提高痰检水平。
Objective To analyze the results of microscopic examination of sputum smear of Mycobacterium tuberculosis in Dongwuzhumu Banner from 2004 to 2013 by Access and discuss the relationship and influence of various factors such as sample traits and sampling time with the detection rate of Mycobacterium tuberculosis, Effectiveness of TB control in the area. Methods The database of sputum smear results of Mycobacterium tuberculosis was established by using Microsoft Office Access and the results of microscopic examination were statistically analyzed. Results The total number of sputum smear peaked in 2008, showing a declining trend year by year, the positive rate of sputum smear also showed a downward trend year by year; sputum smear positive rate was 15.83%, night sputum smear positive rate was 14.65% Sputum smear positive rate was 13.52%; sputum samples the highest pass rate was 59.53%, instant sputum was 58.57%, night sputum was 50.67%; cheese-like sputum positive rate was 37.12%, blood sputum was 23.74%, mucus sputum 14.74% and salivary phlegm 2.80%. Conclusion The TB control in the area under the DOTS strategy has been effectively controlled. Statistical analysis concluded that the quality of sputum samples collected, the quality of the filming and reading of the test staff are important factors affecting the positive detection rate of sputum smear of Mycobacterium tuberculosis, should guide the patient to grasp the method of sputum to improve the quality of sputum specimens , Strengthen the construction of laboratory inspectors and quality control, improve sputum examination level.
