我院ICU多重耐药鲍曼不动杆菌聚集性病例与环境污染调查分析 : = Investigation and analysis on multidrug-resistant Acinetobacter baumannii infection cases and environmental pollution in ICU
目的调查我院重症监护病房(intensive care unit,ICU)多重耐药鲍曼不动杆菌(multidrug-resistant Acinetobacter baumannii,MDR-AB)医院获得性肺炎聚集性病例与医院环境污染的相关性,为预防和控制ICU患者MDR-AB医院感染提供环境流行病学依据。方法采用现场流行病学调查方法,对短时间内我院ICU出现的3例MDR-AB医院获得性肺炎患者、周围环境以及医务人员标本进行干预前后大面积环境卫生学采样监测,用VITEK-2 Compact全自动细菌鉴定及药敏分析系统进行菌株鉴定与药敏分析。采取分区分色管理方法实施强化环境清洁消毒等综合干预措施,追踪干预效果。结果对干预前80份环境标本进行微生物监测,其中护理站电脑键盘、医护人员手、床单、手消压盖、抢救车剪刀、回风口、患者胸部皮肤、隔离衣袖口、床挡板扶手等14份标本分离出鲍曼不动杆菌,其耐药谱与痰培养耐药菌株相一致。干预后连续2个月环境采样146份标本,均未检出MDR-AB。连续实施干预措施6个月后,标本合格率由77.50%上升至96.57%,医院感染率由干预前2.15%(214/9 965)下降至1.56%(185/11 866),差异均有统计学意义(P<0.05)。结论 MDR-AB医院感染的发生与患者周围环境污染密切相关,分区分色强化环境清洁消毒等综合干预措施可以有效降低医院感染暴发风险。.
Objective To investigate the relevance between the multidrug-resistant Acinetobacter baumannii(MDR-AB) hospital acquired pneumonia and environmental pollution in intensive care unit(ICU). Based on the result, we can provide environmental and epidemiological basis for preventing and controlling MDR-AB nosocomial infection in ICU patients. Methods With field epidemiological investigation method, we carried out large area hygiene sampling monitoring on three MDR-AB hospital acquired pneumonia patients,environment and medical staff in ICU before and after the intervention. Using VITEK-2 Compact bacteria identification and drug susceptibility analysis system we identified the specific strain of bacteria and corresponding drug susceptibility. Zone and color separation method was adopted in the environmental sterilization and the effect of intervention was traced. Results Before the intervention we monitored 80 environmental samples. MDR-AB strains of consistent drug-resistant patterns with previous MDR-AB strains isolated from patients′ sputum cultures were found in 14 samples, including computer keyboards at the nursing station, hands of medical staff, bed sheets, lids of hand disinfection solution, scissors in rescue vehicles, air-returning outlets, patients chest skin, cuffs of isolation clothes and bed baffle handrails. No MDR-AB was found in 146 environmental samples after the intervention in the following two months. Six months after the intervention. The qualified rate of specimens increased from 77.50% to 96.57%, and the hospital infection rate decreased from 2.15%(214/9 965) to 1.56%(185/11 866). Which was of significant difference from the rate before the intervention(P<0.05). Conclusion The occurrence of MDR-AB hospital infection is highly related to the environmental pollution. Intervention with sterilization based on zone and color separation can effectively lower the risk of hospital infection outbreak..
