某院骨科住院患者医院感染危险因素回顾性调查

目的探讨某院骨科住院患者发生医院感染的相关危险因素，为预防医院感染提供科学依据。方法回顾性分析2011年1月-2012年12月该院骨科住院患者病历资料3 776份。结果发生医院感染79例，医院感染率为2.09%；感染部位以下呼吸道为主（占30.38%），其次为切口感染（占26.58%）；分离病原菌79株，革兰阴性杆菌58株（73.42%），革兰阳性球菌21株（26.58%）。骨科患者发生医院感染相关的危险因素有：年龄、住院天数、手术（手术类型和方式）以及合并糖尿病。结论骨科住院患者易发生呼吸道和手术切口感染，应针对其危险因素，采取科学的预防控制措施，有效降低医院感染的发生。

Retrospective analysis on risk factors for healthcare associated infection in hospitalized patients at an orthopaedics department of a hospital

ObjectiveTo explore the risk factors for healthcare associated infection (HAI) in hospitalized patients at an orthopaedics department of a hospital, and provide reference for the prevention of HAI. MethodsClinical data of 3 776 hospitalized patients between January 2011 and December 2012 were reviewed retrospectively.ResultsA total of 79 cases (2.09%) of HAI occurred, the most common infection site was lower respiratory tract（30.38%）,followed by surgical site（26.58%）; 79 pathogenic strains were isolated, 58 （73.42%）of which were gram negative bacilli, 21（26.58%） were gram positive cocci. The risk factors for HAI in patients with orthopaedics diseases were age, length of hospital stay, surgery(types and modes), and associated diabetes mellitus.ConclusionOrthopaedics patients are vulnerable to respiratory tract and surgical site infection, corresponding measures should be taken to reduce the incidence effectively.
