应用加权秩和比法综合评估血吸虫防治效果

目的应用加权秩和比法综合评估血吸虫病防治效果,为血吸虫病防治及政策制定提供参考。方法选择反映血吸虫防治效果三个方面的疫情指标体系:人群感染情况、家畜感染情况、洲滩危险指标,并通过德尔菲法建立各指标的组合权重,再应用加权秩和比(RSRw)法对3个试点村连续4年的防治效果指标进行综合测评。结果试点村中双坪村及利兴村的RSRw时间序列值逐年升高,并在2009年达到最高,预示着两村的血吸虫病防治效果较好且呈逐年上升趋势,而灯塔村的RSRw时间序列值有所波动,且存在下滑趋势,意味着灯塔村的血吸虫病防治效果欠佳,防治工作质量有待加强。结论加权秩和比法可克服单一评估指标的不足,给人整体感,所包含信息量大,操作简单,应用性强,在评估血吸虫病防治效果中能综合直观地反映血吸虫病的防治效果及趋势,可为血吸虫病防治政策的制定及防治重点提供科学的参考。
