基层综合陛医院连续3年医院感染调查分析

目的探讨基层综合性医院住院患者医院感染的特点，以采取相应有效措施预防和控制医院感染的发生。方法采用回顾性统计调查分析。结果医院感染率为1．63％，其中以呼吸道最高，依次为泌尿道、手术切口；临床分离的致病菌为G-菌，占55．45％，G＋菌，占20％，真菌，占24．55％，比较本院近3年医院感染，条件致病菌各年构成比差异虽无统计学意义，但仍占主导地位。结论加强医院感染管理，减少侵袭性操作，及时病原菌监测，合理应用抗菌药物是降低医院感染的有效措施。

Nosocomial Infections of Inpatients:An 3-year Clinical Investigation and Analysis in Basic-level general hospital

Objective To investigate the feature of nosocomial infections in Basic-level general hospital, based on which effective methods are taken to prevent and control the incidence of nosocomial infection. Methods An analysis was made on the basis of the survey, the data came from hospitalized cases in the recent three years. Results The rate of nosocomial fungus infection was 1.63 %,the main infection site was respiratory tract, and followed by urinary tract and surgical incision. Among bacteria isolated from clinical cases, 55.45 % were G-, 20.00 % were G+, and 24.55 % were fungi. However,differences of the proportion of conditional bacteria were insignificantly (P＞0.05) during the past three years,the conditional bacteria were the major pathogenic in nosocomial infections. Conclusions Strengthening the nosocomial infection management, Lessing invasive process, supervising towards bacteria, and using antibacterial drug rationally are effective methods to reducing the nosocomial infections.
