妇科肿瘤PICC患者院外导管相关性感染危险因素的Logistic回归分析

Risk factors of catheter-related infection outside hospital in gynecologic tumor patients with indwelling PICC: a logistic regression analysis

目的探讨留置PICC的妇科肿瘤患者发生院外导管相关性感染的危险因素。方法对在我科留置PICC的421例妇科肿瘤患者的相关资料进行收集和整理,分析患者发生院外导管相关性感染的相关因素,并进一步行Logistic回归分析。结果 48例发生院外导管相关性感染,总感染率为11.4%。单因素分析显示:患者的文化程度、居住地、季节、导管留置时间、换药周期、换药地点、导管移动及合并基础疾病与患者PICC院外感染相关(P均<0.05)。Logistic回归分析提示文化程度低、春季、导管留置时间长、发生导管移动、合并基础疾病是妇科肿瘤PICC患者发生院外导管相关性感染的独立危险因素。结论留置PICC的妇科肿瘤患者发生院外导管相关性感染较常见,并且与多个因素相关,减少感染需从相关方面加以防范。

ObjectiveTo explore the risk factors of catheter-related infection outside hospital in gynecologic tumor patients with indwelling PICC. MethodsData of 421 gynecologic tumor patients with indwelling PICC in our department were collected. The related factors of catheter-related infection outside hospital were analyzed. Then Logistic regression analysis was performed. ResultsA total of 48 patients suffered from catheter-related infection outside hospital,and the total infection rate was 11.4%. The univariate analysis showed that catheter-related infection outside hospital was related to the education level, place of residence, season, duration for indwelling catheter, frequency and location of dressing change, movement of catheter and complication of basic diseases（all P〈0.05）. Logistic regression analysis showed low education level, spring, indwelling catheter for a long time, catheter movement and complication of basic diseases were the independent risk factors of catheter-related infection outside hospital in gynecologic tumor patients with indwelling PICC. ConclusionIt is common that gynecologic tumor patients with indwelling PICC suffer from catheter-related infection outside hospital. And it is associated with multiple factors. Related measures should be performed to reduce the infection.
