目的了解多重耐药菌(MDRO)的分布情况,研究干预措施在控制MDRO医院感染中的作用。方法采用前瞻性病例监测方法,对2013年和采取加强手卫生、落实隔离等干预措施的2014年某综合医院MDRO患者进行监测,并分析干预效果。结果 2013年共监测MDRO患者370例,其中医院感染207例;采取干预措施的2014年MDRO患者297例,其中医院感染122例。干预后全院MDRO医院感染率由2013年的4.43‰下降为2014年的2.36‰(χ~2=31.394,P<0.05),其中ICU、干部科、烧伤科的MDRO医院感染率下降明显,分别由71.83‰、6.34‰和16.34‰下降至42.02‰(χ~2=14.638,P<0.05)、1.02‰(χ~2=7.440,P<0.05)和1.65‰(χ~2=7.327,P<0.05),移植外科、神经外科和其他科室2013年与2014年MDRO的医院感染率差异无统计学意义。2年内MDRO医院感染部位以呼吸道为主,占77.51%。结论加强手卫生、落实隔离措施等干预手段可以有效防控MDRO的医院感染。
Objective To understand the distribution of multidrug-resistant bacteria (MDRO) and to investigate the role of interventions in controlling MDRO nosocomial infections. Methods A prospective case-monitoring method was used to monitor the 2014 MDRO patients in a general hospital in 2013 and to adopt intervention measures such as strengthening hand hygiene and implementing isolation, and to analyze the intervention effect. Results A total of 370 MDR patients were monitored in 2013, of which 207 were hospital-based infections. In 2014, 297 MDR patients were intervened, of which 122 were hospital-acquired infections. After the intervention, the hospital infection rate of MDRO hospital decreased from 4.43 ‰ in 2013 to 2.36 ‰ in 2014 (χ ~ 2 = 31.394, P <0.05), and the infection rate of MDRO in ICU, cadre department and burn department decreased significantly (P <0.05), and decreased from 71.83 ‰, 6.34 ‰ and 16.34 ‰ to 42.02 ‰ (χ ~ 2 = 14.638, P <0.05) 0.05). There was no significant difference in hospital infection rates between MDRO in transplant surgery, neurosurgery and other departments in 2013 and 2014. MDRO hospital infection within 2 years mainly respiratory tract, accounting for 77.51%. Conclusion Intensive hand hygiene and the implementation of isolation measures and other interventions can effectively prevent and control MDRO nosocomial infections.
