精神专科医院院内感染现状调查

Investigation on the status of nosocomial infection in psychiatric hospital

目的对精神专科医院感染现状进行调查分析,为医院感染的预防和控制提供依据。方法采用回顾性调查与前瞻性监测相结合的方式,对某三级甲等精神专科医院2017年1月~2018年6月住院及出院的9838例患者中发生医院感染病例进行调查监测。结果共计发生医院感染146例,感染率为1.48%;感染相关死亡病例5例,约占3.42%;不同科室间医院感染发生率有所不同,以老年精神科发生为高发科室,感染率为3.50%,心身科感染率最低,为0.09%;感染部位以下呼吸道感染为主,占67.1%,其次为上呼吸道(16.44%)、泌尿道(11.64%);病原学检查141例,病原学送检率为96.58%,阳性率为19.18%,分离到病原菌67株,以革兰阴性菌为主。结论进一步加强医院感染管理,采取预防和控制措施,降低呼吸道感染,有效降低医院感染发生率。

Objective To investigate and analyze the current status of infection in psychiatric hospitals,and to provide evidence for prevention and control of nosocomial infections.Methods A retrospective survey and prospective surveillance were combined to investigate the incidence of nosocomial infections in 9838 patients who were hospitalized and discharged from January 2017 to June 2018 in a third-grade psychiatric hospital.Results A total of 146 cases of nosocomial infection occurred,with the infection rate of 1.48%.There were 5 cases of infection-related deaths,accounting for 3.42%.The incidence of nosocomial infections in different departments was different,and the incidence of geriatric psychiatry was high,with the infection rate of 3.50%.The psychosomatic infection rate was the lowest,accounting for 0.09%.The respiratory infections were mainly in the lower respiratory tract infection,accounting for 67.1%,followed by the upper respiratory tract(16.44%)and the urinary tract(11.64%).There were 141 cases of pathogenic examinations,and the pathogen examination rate was 96.58%,with the positive rate of 19.18%.And 67 strains of pathogens were isolated,mainly Gram-negative bacteria.Conclusion It can effectively reduce the incidence of nosocomial infections by further strengthening hospital infection management,taking preventive and control measures.
