This study was designed to assess the overall prevalence of infection among the patients in hospitals in the UK and the Republic of Ireland. Patient data were collected and entered directly into a portable Olivetti (A12 notebook) computer with a custom-designed program (Epi-Info version 5.01). The statistical analysis was performed using the Statistical Package for Social Sciences software (SPSS). In all, 37,111 patients from 157 centers were studied, and a mean hospital acquired infection (HAI) prevalence rate of 9.0% (range 2-29%) was calculated. HAI rates were higher in teaching hospitals (11.2%) than in non-teaching hospitals (8.4%) P < 0.001. Four major sites of infections--infections of the urinary tract (23.2%), surgical-wound infections (10.7%), lower-respiratory tract (22.9%) and skin infections (9.6%)--accounted for 66.5% (2559 of 3848) of the total infections identified.
本研究旨在评估英国和爱尔兰共和国医院患者的总体感染率。收集患者数据并直接录入一台配备定制程序（Epi-Info 5.01版）的便携式好利获得（A12笔记本）电脑。使用社会科学统计软件包（SPSS）进行统计分析。总共对来自157个中心的37111名患者进行了研究，计算出医院获得性感染（HAI）的平均患病率为9.0%（范围为2%-29%）。教学医院的HAI发生率（11.2%）高于非教学医院（8.4%），P<0.001。四个主要感染部位——尿路感染（23.2%）、手术伤口感染（10.7%）、下呼吸道感染（22.9%）和皮肤感染（9.6%）——占已确定总感染的66.5%（3848例中的2559例）。
