Relationship between hospital ward design and healthcare associated infection rates: what does the evidence really tell us? Comment on Stiller et al. 2016

摘要

The systematic review published by Stiller et al. in Antimicrobial Resistance & Infection Control in November 2016 concludes that single-patient bedrooms confer a significant benefit for protecting patients from healthcare associated infection and colonization. This conclusion is not substantiated by the evidence included in their review which has been largely drawn from uncontrolled before and after studies in the absence of a transparent assessment of the risk of bias. There are also errors in the analysis of supporting data. Evaluating the specific impact of single rooms on preventing transmission from a sound epidemiological perspective is essential to assure safe and effective care and a clear evidence-base for infection prevention and control advice.
