目的了解外科重症监护病房(SICU)多药耐药鲍氏不动杆菌院内暴发的流行病学资料,探讨医院感染暴发的危险因素,为有效预防与控制感染暴发流行提供理论依据。方法采用回顾性调查的方法,对2015年5月4日-12日SICU发生的7例多药耐药鲍氏不动杆菌感染病例进行调查分析。结果 2015年5月4日-12日SICU33例住院患者中7例检出多药耐药鲍氏不动杆菌,罹患率为21.21%;感染部位为下呼吸道感染6例(占85.71%),血流感染1例(占14.29%);7株鲍氏不动杆菌对抗菌药物的耐药谱基本一致;对多药耐药鲍氏不动杆菌感染患者进行集中隔离、加强医务人员无菌操作流程、手卫生以及加强环境清洁与物品消毒管理等,有效控制了感染的发生。结论隔离措施不规范,侵入性操作多,医务人员手卫生意识差、环境消毒落实不到位是多药耐药鲍氏不动杆菌院内暴发流行的重要原因,多部门协作采取综合性干预措施,可以有效预防与控制医院感染暴发流行的发生。
Objective To understand the epidemiological data of hospitalized outbreaks of multidrug-resistant Acinetobacter baumannii in surgical intensive care unit (SICU) and to explore the risk factors of outbreaks of nosocomial infection in order to provide a theoretical basis for effective prevention and control of outbreaks of infection. Methods A retrospective survey was conducted to investigate the incidence of multidrug-resistant Acinetobacter baumannii infection in SICU from May 4 to May 12, 2015. Results From May 4 to May 12, 2015, 7 out of 33 hospitalized patients with SICU were detected with multi-drug resistant Acinetobacter baumannii, with a prevalence rate of 21.21%, 6 cases (85.71%) with lower respiratory tract infection, and blood 1 case of influenza infection (accounting for 14.29%); 7 strains of Acinetobacter baumannii antibacterial drug resistance spectrum is basically the same; multi-drug resistant Acinetobacter baumannii infection in patients with intensive isolation and strengthen the medical staff aseptic process , Hand hygiene as well as strengthening environmental sanitation and articles disinfection management, effectively control the incidence of infection. Conclusion Non-standard isolation measures, invasive operation, poor health awareness of hand-hygiene staff, inadequate implementation of environmental disinfection is an important reason for the outbreak of multidrug-resistant Acinetobacter baumannii in hospital, and multi-departmental collaboration to take comprehensive interventions, Effective prevention and control of nosocomial infections outbreaks.
