目的了解重症监护室(ICU)手术患者多重耐药菌(MDROS)感染现状及危险因素,为预防与控制MDROs感染提供参考依据。方法通过回顾性调查和目标性监测,对某医院ICU手术患者MDROs的感染情况进行监测,分析相关危险因素。结果该医院ICU共收治患者5 081例,包括手术患者859例和非手术患者4 222例。手术患者中发生MDROs感染268例,感染率31.20%;非手术患者中发生MDROs感染1 069例,感染率25.32%。MDROs感染与神经外科、胸外科、骨科等科室的手术及APACHEⅡ评分分值高(≥21分)有密切关系,构成MDROs感染的主要危险因素。结论 ICU手术患者MDROs感染率明显高于非手术患者,应将高危科室手术患者作为MDROs感染重点防控对象,采取必要的预防控制措施。
Objective To understand the status and risk factors of multi-drug resistant bacteria (MDROS) infection in intensive care unit (ICU) patients and provide a reference for prevention and control of MDROs infection. Methods Through retrospective investigation and targeted monitoring, the infection status of MDROs in ICU patients in a hospital was monitored to analyze the relevant risk factors. Results A total of 5 081 patients were admitted to the hospital ICU, including 859 cases of surgery and 4 222 cases of non-surgical patients. There were 268 cases of MDROs infection in the surgical patients, the infection rate was 31.20%; 1069 cases of MDROs infection in non-surgical patients, the infection rate was 25.32%. MDROs infection and neurosurgery, thoracic surgery, orthopedics and other departments of surgery and APACHE Ⅱ score score (≥ 21 points) are closely related to constitute a major risk factor for MDROs infection. Conclusion The infection rate of MDROs in patients undergoing ICU surgery is significantly higher than that of non-operation patients. Patients in high-risk department should be regarded as the key prevention and control targets of MDROs infection and the necessary preventive and control measures should be taken.
