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 | Antimicrobial Resistance & Infection Control
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.
