低疟区疟疾病例侦查的成本——效果分析

COST EFFECTIVENESS OF MALARIA CASE DETECTION IN LOW LEVEL MALARIA ENDEMIC AREA,HUBEI

１９９５—１９９６年在湖北省的江陵、仙桃两县市进行低疟区简化病例侦查方法的研究。结果显示：每个发热病人的血检费用为１．７８元，以二热病人为血检对象的简化病例侦查方案，原虫检出率为９．４５％，一次血检检出的阳性人数占总阳性人数的９５．３８％，检出每个阳性病例的费用为１８．８６元，而以四热病人为血检对象则费用要增加１８０倍，且两种病例侦查方案在降低疟疾发病方面无显著性的差异，同样可以取得较好的防治效果。从流行病学和卫生经济学综合评价，在以中华按蚊为唯一媒价的低疟区，以二热病人为血检对象的病例侦查方案，大幅度减少了血检数量，提高了措施的针对性，可以巩固疟疾防治成果，节省大量的人力、物力和财力，是经济有效。

A simplified schemes of malaria case detection has been conducted in 1995—1996 in Xiantao and Jiangling,Hubei Province The result shows that 124414 blood slide was taken from fever cases and the average cost for each blood slide taking was RMB 1 78 yuan The blood slide was taken from the clinical case of malaria and was thought to be malaria,the parasite rate was 9 45% and positive detected rate was 95 38%,its expenditure in each case was RMB 18 86 yuan If the blood slide was taken by all fever cases and expenditure for each case was 180 times than former But,there were not statistical difference in incidence in both schemes in the low level malaria endemic area As the final control effect was very similar in two schemes From the point of view of view of assessment in epidemiology and hygienic economics,the first scheme is effective,reasonable and economical measure to use in low level malaria endemic area where the vector is Anopheles sinensis It can be rapid decreasing blood examination amount,increasing aim and save money,manpower
