摘要
目的 建立新的肺结核病涂阳患病率调查方法及其推算公式。 方法 利用肺结核可疑症状者与无肺结核可疑症状者涂阳病人数构成比的参数作常数 ,建立直接症状检查法及其推数公式 ,并作费用分析。 结果 有肺结核可疑症状者与无结核症状者的涂阳病人比例 ,分别为 75 %和 2 5 %。以此参数建立的 (直接症状检查法 )肺结核涂阳患病率计算公式为 :R=Sn× (1+1/3) /N。式中 R为肺结核涂阳患病率 ;Sn为有症状者患病人数 ;N为调查人数。直接症状检查法调查费用低 ,仅为普查法的 2 4 .3%。 结论 新建立的直接症状检查法样本大、参数 (常数 )稳定、科学性好、调查方法简便、实施工作费用低 。
Objective To establish a new method and calculation formula for the prevalence of smear positive tuberculosis survey. Methods Using parameter of the smear positive tuberculosis patients between patients with suspect system and without suspect system, establish a new method and calculation formula. Result 1.The proportion of the smear positive tuberculosis patients between patients with suspect system and without suspect system patients 75% and 25% respectively. The formula was established as following:R=Sn×(1+1/3)/N, R is prevalence of smear positive tuberculosis, Sn is the number of smear positive tuberculosis among patients with suspect symptom, N is the total number surveyed. 2.The cost of the survey in this way is lower than the routine method. Conclusion The new method is scientific, simple, convenient and with, low cost. The method and formula can be used for survey of prevalence of sputum smear positive pulmonary tuberculosis.
