摘要
目的分析某教学医院重症监护病房(ICU)导管相关医院感染及其病原微生物的情况。方法采用前瞻性调查,对2015年1月1日—11月30日所有入住ICU>48 h的患者进行目标性监测,对侵入性操作相关医院感染病例进行分析,以美国疾病控制与预防中心(CDC)颁布的指南作为诊断依据,标准化模式进行数据收集,并采用描述性研究进行统计分析。结果 2015年1—11月共监测254例ICU住院患者。导管相关医院感染(DA-HAIs)例次发病率为15.35%,例次日感染发病率为10.23‰。呼吸机相关肺炎(VAP),导尿管相关尿路感染(CAUTI)及血管导管相关血流感染(CLABSI)发病率分别为7.05‰、4.91‰及3.22‰。ICU医院感染的主要部位为下呼吸道(48.27%),其次为血液系统(27.59%)、泌尿系统(22.99%)及消化系统(1.15%),常见病原菌为鲍曼不动杆菌,占21.52%。结论该目标性监测系统能有效识别ICU导管相关医院感染的流行病学现状与趋势,并制定有效控制措施,从而确保医疗质量安全。
Objective To identify the occurrence and microorganism profile of device-associated healthcare-associa-ted infections （DA-HAIs）in the intensive care unit （ICU）of a university hospital in China.Methods From Janua-ry 1 to November 30,2015,patients admitted to the ICU of a university hospital in China for more than 48 hours were performed prospective descriptive study. DA-HAIs were defined according to the criteria of the Centers for Disease Control and Prevention （CDC）of U.S.,descriptive statistical analysis was performed.Results Of 254 pa-tients admitted to ICU,the overall incidence of DA-HAIs was 15.35% ,with 10.23 cases of DA-HAIs per 1 000 ICU-days;the incidence of ventilator-associated pneumonia （VAP ）,catheter-associated urinary tract infection （CAUTI）,and central line-associated bloodstream infection （CLABSI）were 7.05 per 1 000 ventilator-days,4.91 per 1 000 urinary catheter-days,and 3.22 per 1 000 central line-days,respectively. The main infection site was lower respiratory tract,accounting for 48. 27% ,followed by bloodstream system （27. 59% ）,urinary tract （22.99% ）,and gastrointestinal tract（1.15% ）. The major isolated microorganism was Acinetobacterbaumannii （21 .52% ）.Conclusion The surveillance system can identify the epidemiological status of DA-HAIs and make effec-tive control measures to ensure the healthcare safety.
