摘要(Abstract):
目的 筛选重症监护室(ICU)患者耐碳青霉烯类肺炎克雷伯菌(CRKP)感染的危险因素,为降低CRKP感染率提供有力依据。方法 选择2019年1月1日-2021年12月31日解放军总医院第一医学中心ICU收治的406例CRKP感染患者为CRKP组,按照1∶1的比例选取同期414例碳青霉烯类敏感肺炎克雷伯菌(CSKP)感染患者为CSKP组。采用病例回顾性对照研究,单因素与多因素Logistic回归分析CRKP感染的危险因素。结果 两组标本均以痰液为主,分别为46.05%和62.07%;单因素分析结果显示:年龄>60岁,住院天数>14 d,感染部位为下呼吸道、泌尿道、血液系统,基础疾病包括呼吸衰竭、肝脏疾病、低蛋白血症、心血管疾病、贫血、电解质紊乱、糖尿病、意识障碍,侵入性操作包括手术、机械通气、泌尿道插管,合并其他细菌感染、联合使用抗菌药物>3种、使用碳青霉烯类抗菌药物、感染前用药>10 d是CRKP感染的危险因素(P<0.05);多因素Logistic回归分析结果显示:呼吸衰竭、贫血,侵入性操作中手术、机械通气、泌尿道插管,联合使用抗菌药物>3种以及感染前使用碳青霉烯类抗菌药物是CRKP感染的独立危险因素(P<0.05)。结论 针对CRKP感染高风险患者应加强评估,提升机体抵抗力,避免侵入性诊疗操作,规范使用抗菌药物,严格执行无菌操作和手卫生规范,降低住院患者CRKP感染的风险。
