【摘要】：目的了解某院血液病医院住院患者医院感染情况,为有效控制和预防医院感染提供依据。方法采用病历查阅和床旁调查相结合的方法,调查该院2012—2014年血液病住院患者医院感染情况。结果共调查患者1 963例,2012—2014年医院感染现患率分别是20.44%、20.76%、22.70%;感染部位主要以下呼吸道为主(34.50%~36.18%),其次为皮肤与软组织和上呼吸道。检出病原菌207株,其中革兰阴性杆菌139株(67.15%),革兰阳性球菌47株(22.71%),真菌21株(10.14%),主要致病菌为大肠埃希菌(50株)、肺炎克雷伯菌(24株)、铜绿假单胞菌(17株)。医院感染现患率3年均以移植科最高(30.16%~32.69%),其次为白血病科(25.26%~29.35%)和骨髓增生异常综合征(MDS)科(21.95%~25.00%)。血液儿科3年现患率比较,差异有统计学意义(χ2=9.66,P=0.008),其他科室3年现患率比较,差异无统计学意义。多重耐药菌由2012年的12株增加至2014年的22株,以大肠埃希菌为主。结论医院感染现患率较高,大肠埃希菌为主要致病菌和多重耐药菌,应加强对感染高发科室、部位以及重点致病菌感染等高危因素的监测,并采取相应干预措施,减少医院感染。
[Abstract]:Objective to investigate the nosocomial infection in patients with hematologic diseases in a hospital and to provide evidence for the effective control and prevention of nosocomial infection. Methods Nosocomial infection in patients with hematologic diseases from 2012 to 2014 was investigated by means of medical records and bedside surveys. Results the prevalence rate of nosocomial infection in 1 963 patients from 2012 to 2014 was 20.440.76 and 22.700.The main respiratory tract below the infection site was 34.50,36.18, followed by skin and soft tissue and upper respiratory tract. Among 207 strains of pathogenic bacteria, 139 strains were Gram-negative bacilli, 47 strains were Gram-positive cocci, and 21 strains were fungi. The main pathogenic bacteria were Escherichia coli (50 strains), Klebsiella pneumoniae (24 strains) and Pseudomonas aeruginosa (17 strains). The main pathogenic bacteria were Escherichia coli (50 strains), Klebsiella pneumoniae (24 strains) and Pseudomonas aeruginosa (17 strains). The incidence of nosocomial infection in 3 years was the highest in transplant department (30.16), followed by leukemia (25.26) and myelodysplastic syndrome (MDS) (21.95%). There was significant difference in the incidence rate of blood pediatrics in 3 years (蠂 2 9. 66% P 0. 008%), but there was no significant difference in 3 years prevalence rate in other departments. The number of multidrug resistant bacteria increased from 12 strains in 2012 to 22 strains in 2014, mainly Escherichia coli. Conclusion the prevalence rate of nosocomial infection is high. Escherichia coli is the main pathogenic bacteria and multidrug resistant bacteria. Reduce nosocomial infections.
