This article (a follow on from an article concentrating on Northern Ireland) examines the relationship between percentage bed occupancy (PO), turnover interval (TI) and methicillin-resistant Staphylococcus aureus (MRSA) rates in the acute beds of specialist English hospital trusts and describes the TI and levels of bed occupancy. The data were collected from publicly available data: MRSA rates of blood-borne infection per 1000 bed days from the Department of Health; average length of stay from Hospital Episode Statistics; and percentage occupancy from the Department of Health Hospital Activity statistics were used. Pearson's Correlation coefficients were used as basis for inferential analysis. The mean TI for all trusts was as 0.94 days, median 0.95 days. Twenty percent of trusts had TIs, on average, of less than 0.58 days (13.9 hours) and 10% had a TI less than 0.32 days (7.6 hours). The mean PO was 84.98% and the median was 84.76%. Seventy percent of the trusts exceeded the recommended 82% bed occupancy. The inference from this study is that there is a relationship between TI and PO and rate of MRSA infection in specialist English hospitals and that PO rates are at a level which may interfere with good infection control procedures.
本文（是一篇聚焦北爱尔兰的文章的后续）研究了英国专科医院信托急症床位的床位占用率（PO）、周转间隔（TI）与耐甲氧西林金黄色葡萄球菌（MRSA）感染率之间的关系，并描述了周转间隔和床位占用水平。数据收集自公开可得的数据：来自卫生部的每1000个床日血行感染的MRSA感染率；来自医院事件统计数据的平均住院时间；以及来自卫生部医院活动统计数据的床位占用率。皮尔逊相关系数被用作推断分析的基础。所有信托的平均周转间隔为0.94天，中位数为0.95天。20%的信托平均周转间隔小于0.58天（13.9小时），10%的信托周转间隔小于0.32天（7.6小时）。平均床位占用率为84.98%，中位数为84.76%。70%的信托超过了建议的82%的床位占用率。该研究的推断是，在英国专科医院中，周转间隔、床位占用率与MRSA感染率之间存在关联，且床位占用率处于可能干扰良好感染控制程序的水平。
