目的掌握三峡库区宜昌监测点法定报告传染病的发病情况,为制定传染病防控策略提供理论依据。方法按随机抽样的原则,对各监测点居民法定报告传染病及医疗机构法定报告传染病漏报情况进行调查。结果共调查居民法定报告传染病患者33例,漏报14例,漏报率为42.42%。其中乙类传染病漏报率为15%,丙类传染病漏报率为84.62%,丙类传染病漏报率明显高于乙类传染病,有统计学意义差异(χ2=15.63,P<0.01)。共调查医疗机构登记传染病362例,报告342例,漏报20例,漏报率为5.52%。结论三峡库区宜昌监测点丙类传染病漏报率较高,村级医疗机构漏报严重,需加大法定报告传染病报告工作的监督管理力度。
Objective To grasp the incidence of statutory reporting of infectious diseases in Yichang monitoring sites in the Three Gorges Reservoir Area and to provide a theoretical basis for the development of prevention and control strategies for infectious diseases. Methods According to the principle of random sampling, we investigated the statutory report communicable diseases of residents and statutory report communicable diseases of medical institutions at each monitoring point. Results A total of 33 cases of infectious diseases reported by residents were investigated, missing in 14 cases and the false negative rate was 42.42%. Among them, the omission rate of Class B infectious diseases was 15%, the false negative rate of Class C infectious diseases was 84.62%, the false negative rate of Class C infectious diseases was significantly higher than that of Group B infectious diseases with statistical significance (χ2 = 15.63, P < 0.01). A total of 362 cases of infectious diseases registered in medical institutions were investigated, including 342 reported cases, 20 cases of under-reporting, and an underreporting rate of 5.52%. Conclusion The misdiagnosis rate of Category C infectious diseases in Yichang monitoring sites in the Three Gorges Reservoir Area is high, and the omission of report at the village level medical institutions is serious. Supervision and management of statutory reporting of infectious diseases needs to be stepped up.
