目的为了准确并及时发现和找出病人,严格控制痰涂片质量,提高涂阳结核病人的发现率。方法在项目进行中的每一年都随机对部分项目县痰涂片进行抽样检查,并与项目县上报的自检结果进行比较分析。结果湖南省卫Ⅴ项目启动时的1992年,结核病可疑者检出率仅为10.23%,痰检阳性率为21.29%;项目结束时的2001年,结核病可疑者检出率和痰检阳性率分别为20.11%和32.53%,均有明显提高(χ2=1 502.7、234.2,P均<0.01);痰涂片制片合格率为93.12%,假阳性率为0.69%,假阴性率为0.93%。结论湖南省卫Ⅴ项目期间,由于注重痰检质量,结核病可疑者检出率痰检阳性率都有明显提高,涂片制片合格率、假阴性率和假阳性符合率都达到了国家项目所规定的质量要求。
Objective To accurately and promptly find and identify patients, strictly control the quality of sputum smear and improve the detection rate of smear positive tuberculosis patients. Methods The sputum smear of some project counties was randomly sampled in each year of the project and compared with the self-test results reported by the project counties. Results In 1992, when the Wei-Ⅴ project was started in Hunan Province, the detection rate of suspected TB was only 10.23% and the positive rate of sputum was 21.29%. At the end of the project in 2001, the detection rate of TB suspected and the positive rate of sputum were (Χ2 = 1 502.7,234.2, P <0.01). The passing rate of sputum smear was 93.12%, the false positive rate was 0.69%, and the false negative rate was 0.93%. Conclusion During the course of Wei-Ⅴ project in Hunan province, due to the quality of sputum examination, the positive rate of sputum test for suspicious cases of tuberculosis was significantly increased. The coincidence rate of false-negative rate and false-positive rate of smear production reached the national project Prescribed quality requirements.
