医院呼吸道感染在我院医院感染部位构成比中占60％，支气管感染占呼吸道感染80％，与国内外报道的资料基本相似[1]。为了降低医院呼吸道感染率，寻找降低呼吸道感染的有效途径，增强控制院内感染的效果，本文对我院1992年1月～1995年3月的全部出院病历进行了回顾性调查。1调查 Hospital respiratory tract infection in our hospital accounted for 60% of the composition of the site, bronchial infection accounted for 80% of respiratory infections, and the data reported at home and abroad are basically similar [1]. In order to reduce the rate of respiratory tract infection in hospitals and search for effective ways to reduce respiratory infection and to enhance the effectiveness of nosocomial infection control, this paper retrospectively reviewed all the discharged medical records from January 1992 to March 1995 in our hospital. 1 survey
