某院维吾尔族心胸外科手术患者医院感染发病率及影响因素

目的探讨某院维吾尔族心胸外科手术患者医院感染发病率及影响因素。方法回顾性查阅新疆喀什地区某医院心胸外科2010年6月-2014年6月收治的维吾尔族患者病历，记录相关临床资料，调查其术后医院感染发病率，并采用单因素及多因素logistic回归模型分析患者术后医院感染的影响因素。结果共收集779例维吾尔族患者资料，术后发生医院感染53例，医院感染发病率为6.80%。不同感染部位感染发病率由高至低依次为下呼吸道（2.44%），消化道（1.28%）、泌尿道（1.16%）、上呼吸道（1.03%）和手术部位（0.51%）。多因素logistic回归分析结果显示，糖尿病史、 身体质量指数（BMI）≥30 kg/m2、手术时间≥160 min和侵入性操作是维吾尔族心胸外科手术患者医院感染的危险因素。结论该院维吾尔族心胸外科手术患者医院感染发病率较高，主要危险因素有糖尿病史、BMI高、手术时间长和侵入性操作。

Incidence and influencing factors for post operative healthcare associated infection in Uyghur patients undergoing cardiothoracic surgery in a hospital

ObjectiveTo evaluate the incidence and influencing factors for post operative healthcare associated infection(HAI) in Uyghur patients undergoing cardiothoracic surgery in a hospital.MethodsClinical data of Uyghur patients hospitalized in the department of cardiothoracic surgery in a hospital of Kashgar region between June 2010 and June 2014 were collected, incidence of post operative HAI was surveyed. Influencing factors for post operative HAI were analyzed by univariate and multivariate logistic regression models.ResultsA total of 779 patients’ clinical data were collected, 53 patients (6.80%) developed post operative HAI. The major infection sites were lower respiratory tract (2.44%), digestive tract(1.28%), urinary tract(1.16%), upper respiratory tract(1.03%), and surgical sites(0.51%). Multivariate logistic regression analysis showed that history of diabetes, body mass index (BMI) ≥30 kg/m2, duration of operation ≥ 160 minutes, and invasive procedure were risk factors for post operative HAI in Uyghur patients undergoing cardiothoracic surgery.ConclusionIncidence of post operative HAI in Uyghur patients undergoing cardiothoracic surgery in this hospital is high, risk factors for HAI are history of diabetes, high BMI, long duration of operation, and invasive procedure.
