流动人口血吸虫病监测方法、费用与效果分析

Schistosomiasis surveillance in a transient population and cost-and-effect analysis of that approach

目的通过对广东省流动人口监测方法、费用与效果的分析,优化输入性血吸虫病人的防控措施。方法对广东省开展的流动人口血吸虫病主动监测和被动监测结果和监测费用进行统计分析,并作费用-效果分析。结果1986～2007年广东省流动人口常规主动监测、选择性主动监测和被动监测分别监测23249人、13076人和645人;发现输入性慢性病人分别为3例、50例和238例;病原确诊病人分别为1例、6例和8例。检获1例临床诊断病例及1例病原确诊病例的平均费用以常规主动监测最高,选择性主动监测其次,被动监测最低。结论广东省现阶段要重点开展选择性主动监测,同时加强被动监测;选择灵敏感度较高的检查方法以提高监测费用效果。

Objective To examine schistosomiasis surveillance for the transient population in Guangdong Province, to analyze its cost effectiveness, and to optimize prevention and control of imported schistosomiasis. Methods Results and costs of active and passive surveillance of schistosomiasis in the transient population in Guangdong Province were statistically analyzed, and the cost-effectiveness of these approaches were analyzed. Results From 1986 to 2007, the transient population in Guangdong Province underwent routine active surveillance in 23 249 cases, selective active surveillance in 13 076 cases, and passive surveillance in 645 cases. These approaches yielded an imported ehronic illness in 3, 50, and 238 cases, respectively, and the pathogen was confirmed in 1, 6, and 8 cases, respectively. Average costs for a clinical diagnosis and confirmation of the pathogen are highest with routine active surveillance, followed by selective active surveillance and then passive surveillance. Conclusion The current emphasis is to develop the selective active surveillance and enhance passive surveillance at the same time; selecting methods of examination with higher sensitivity will improve the cost-effectiveness of surveillance.
