某三级甲等综合医院胸心外科患者手术部位感染调查

Surgical site infection in patients undergoing cardiothoracic surgery in a tertiary firstclass hospital

摘要:

目的了解胸心外科手术部位感染现状，分析手术部位感染的特征和影响因素，为预防手术部位感染提供依据。方法采用前瞻性监测方法，调查某院2014年1月1日—2015年12月31日胸心外科手术患者的病历资料，监测患者的手术情况及手术部位感染情况等，分析手术部位感染的危险因素。结果共调查手术患者1 953例，手术部位感染31例，发病率1.59%。logistic回归分析结果显示，住院时间、恶性肿瘤、引流管留置时间和手术时长OR（95%CI）分别为8.48（1.12~63.98）、3.99（1.15~13.83）、2.54（1.07~6.02）、2.11（1.01~4.39），是手术部位感染的独立危险因素(均P＜0.05)。结论预防手术部位感染应针对手术部位感染的危险因素采取措施，以降低手术部位感染的发病率。

Abstract:

ObjectiveTo understand the status of surgical site infection(SSI) in department of cardiothoracic surgery, analyze the characteristics and influencing factors of SSI, and provide evidence for the prevention of SSI. MethodsA prospective monitoring method was used to investigate the medical records of patients undergoing cardiothoracic surgery in a hospital from January 1, 2014 to December 31, 2015, operation status and SSI of patients were monitored, risk factors for SSI were analyzed. ResultsA total of 1 953 surgery patients were investigated, 31 had SSI, incidence of SSI was 1.59%. Logistic regression analysis showed that length of hospital stay, malignant tumor, duration of indwelling drainage tube, and long length of operation were independent risk factors for SSI, OR(95%)CI were 8.48(1.12-63.98), 3.99(1.15-13.83), 2.54(1.07-6.02), and 2.11(1.01-4.39) respectively, (all P<0.05). ConclusionSSI prevention measures should be taken according to risk factors of SSI, so as to reduce the incidence of SSI.
