目的了解白银市5岁以下儿童社区获得性肺炎(Community acquired pneumonia,CAP)的疾病负担。方法制定病例定义,采用多阶段抽样,在疫苗接种单位调查5岁以下儿童,了解CAP的发病情况、就医直接和间接花费。结果白银市5岁以下儿童CAP发病密度估计为0.074/人年;城区、农村儿童分别为0.084/人年、0.069/人年;0岁组最低(0.044/人年);1岁组最高(0.088/人年)。每例CAP总费用平均为6 215.9元,其中直接和间接费用分别为4 462.8元和1 753.1元。2016年白银市5岁以下儿童数为97 303人,CAP的总经济负担估计为4 423.7万元。结论白银市5岁以下儿童CAP疾病负担较高;应进一步开展相关疫苗纳入免疫规划的成本效益分析。
Objective To understand the disease burden of community acquired pneumonia (CAP) in children under 5 years of age in Baiyin City. Methods A case definition was developed. Multistage sampling was used to investigate the incidence of CAP in children under 5 years of age in vaccination units, and direct and indirect medical costs were sought.
