海南省某院医院感染状况及危险因素分析

Nosocomial Infection Status and Risk Factors Analysis in a Hospital of Hainan Province

目的分析海南省某院医院感染状况及影响因素,为有效预防控制医院感染提供依据。方法回顾性调查海南省某医院2015年1月-2016年11月出院患者医院感染情况,采用卡方检验进行单因素分析,应用二分类logistic回归方法进行多因素分析。结果 174 271例出院患者中发生医院感染的有3524人,医院感染发生率为2.02%。性别(P=0.004)、年龄(P<0.001)﹑住院天数(P<0.001)﹑静脉置管(P<0.001)、呼吸机(P<0.001)﹑气管切开(P<0.001)是医院感染发生率的影响因素。结论加强对男性患者﹑20岁以下及60岁以上患者防护工作,合理控制住院天数,严格遵循无菌操作规范,强化医院消毒管理有利于降低医院感染发生率。

Objectives To analyze the nosocomial infection status and risk factors in a hospital of Hainan province, so as to provide the basis for effective prevention and control of nosocomial infection. Methods To investigate the status of patients with nosocomial infection retrospectively in a hospital from Hainan Province between January 2015 and December 2016. Chi-square test was adopted for single factor analysis, while binary logistic regression method was applied for multiple factor analysis. Results 3524 cases acquired nosocomial infection among the total 174271 inpatients, with incidence of nosocomial infection being 2.02%. Gender （P=0. 004）, age （P〈 0. 001）, hospitalization days （P 〈 0. 001）, venous catheters （P 〈 0. 001）, ventilator （P 〈 0. 001） and tracheostomy （P〈0. 001） are factors affecting the incidence of nosocomial infection. Conclusions In order to reduce the incidence of nosocomial infections, we should strengthen the protection work for male inpatients, inpatients younger than 20 and older than 60 years old. In addition, reasonable control of hospitalization days, strict adherence to aseptic practices and enhanced hospital disinfection are also necessary.
