精神科住院患者医院内感染情况调查分析

目的了解精神科住院患者医院内感染基本情况,为今后开展医院内感染管理工作提供依据并采取有效的措施。方法天津市安宁医院对100例出院患者的病历资料进行回顾性分析,观察患者的年龄、性别、住院时间、感染部位、医院内感染发生率以及抗菌药物使用率。结果 100例出院患者中发生医院内感染24例,感染率为24%,其中泌尿道感染6例(6%),上呼吸道感染5例(5%),消化道感染4例(4%),皮肤软组织感染5例(5%),牙周感染3例(3%),下呼吸道感染1例(1%)。发生医院内感染患者的年龄为(56.4±14.7)岁,未发生医院内感染患者的年龄为(49.8±13.1)岁,两者比较差异有统计学意义(t=2.088,P=0.039);发生医院内感染患者的平均住院(188.4±135.0)d,未发生感染患者的平均住院(142.7±80.7)d,两者间比较差异有统计学意义(t=2.028,P=0.045)。抗菌药物使用率为24%,高于卫生部"不超过5%"的要求。结论精神科住院患者的医院内感染与年龄、性别、住院时间等有密切关系,因此应针对性地加强对精神科住院患者的有效管理,切实控制医院内感染的发生。

Nosocmial Infection Investigation of Hospitalized Patients with Psychiatric Disorder

Objective To understand the basic situation of nosocomial infection of mental inpatients,to provide the basis for the development of hospital infection management and taking effective measures.Methods Medical records In 100 cases of patients discharged from Tianjin Anning Hospital were analyzed retrospectively,age,sex,length of stay,site of infection,hospital infection rate and the usage of antimicrobial drugs of the patients were observed.Results Among the 100 patients the nosocomial infection happened in 24 cases,the infection rate was 24%,including 6 cases(6%) of urinary tract infection,5 cases(5%) of upper respiratory tract infection,4 cases(4%) of gastrointestinal infection,5 cases(5%) of skin and soft tissue infection,3 cases(3%) of periodontal infection,and 1 case(1%) of lower respiratory tract infection.The nosocomial infected patients were aged(56.4 ± 14.7) years,were bigger than the non-infected patients(49.8 ± 13.1) years,with statistically significant difference(t = 2.088,P = 0.039);the average length of hospital stay of nosocomial infected patients was(188.4 ± 135.0) days,longer than the un-infected patients'(142.7 ± 80.7) days,with statistically significant difference(t = 2.028,P = 0.045).Antibacterial drug use rate was 24%,higher than that of the Ministry of Health " less than 5% " requirement.Conclusion Psychiatric inpatients nosocomial infection rate was closely correlated with age,sex,and duration of hospital stay,so effective management of hospitalized psychiatric patients should be strengthened,to control the nosocomial infection.
