本研究对英国一所医院成人ICU病房的25年(1971年至1995年期间)院内感染的486例病例进行了分析,明确了病原菌、抗菌素的敏感性和感染源等与院内感染的关系,证实了ICU病房病员获得院内感染的危险性高于普通病房。 院内感染是指入院超过24小时,从血中培养得到致病菌的病例。486例院内感染的病例涉及425例患者和570种致病菌。对院内感染的患者血液培养分析,发现从1971年到1990年间,细菌的种类和数量变化较少,
In this study, we analyzed 486 cases of nosocomial infections in ICU wards of a hospital in adults aged 25 years (from 1971 to 1995) in UK and identified the relationship between nosocomial infections such as pathogens, antibiotic sensitivity and infection sources, and confirmed ICU ward patients get nosocomial infection at higher risk than the general ward. Infection in hospital refers to more than 24 hours after admission, from the blood culture to get pathogenic bacteria cases. The 486 cases of nosocomial infections involved 425 patients and 570 pathogens. Analysis of blood cultures in patients with nosocomial infections showed that bacterial species and numbers varied less from 1971 to 1990,
