目的 寻找血吸虫病中度流行区简便、有效、经济、适用的化疗对象筛查方法。方法 分别以粪检、询检、间凝法 (IHA )及胶体染料试纸条法 (DDIA,原称 DSIA)对居民进行血吸虫病筛查 ,并对各方法进行分析和评价。结果 IHA法与粪检总符合率为 72 .33% ,阳性预告值为 2 6 .78% ;DDIA法仅略低于 IHA法 ;询检法相对较差。卫生经济学费用 -效果分析显示 ,IHA法检出 1例感染者所需费用明显高于 DDIA法和询检法。结论 IHA法是一种简便、有效 ,在感染率为 5 % - 10 %的血吸虫病中度流行区较可取的筛查方法 ,但所需费用较高 ;DDIA法是一种较 IHA法更为简便、快速、廉价的方法 ,且敏感性很高 ,较适合于现场筛查
Objective To search for a simple, effective, economical and suitable method of screening chemotherapy for moderately endemic schistosomiasis. Methods Residents were screened for schistosomiasis by fecal examination, interrogation method, intercondensation method (IHA) and colloidal dye test strip method (DDIA, formerly known as DSIA), and the methods were analyzed and evaluated. Results The total coincidence rate of IHA and fecal seizures was 72.33% and the positive predictive value was 26.78%. DDIA method was only slightly lower than IHA method. Health Economics Cost-effectiveness analysis showed that IHA method was significantly higher than the cost of detecting one case of infection and DDIA method and inquiry method. Conclusion The IHA method is a simple and effective screening method for moderate prevalence of schistosomiasis at an infection rate of 5% -10%, but the cost is higher. DDIA is a more effective method than IHA Simple, fast, cheap method, and high sensitivity, more suitable for on-site screening
