Such improvements have undoubtedly been seen in ST elevation myocardial infarction (STEMI),4 Major Trauma5 and Stroke6 (the stroke, trauma and STEMI (STS) group), but importantly, such patients represent less than 5% of ED attendances.Based upon this linkage of system redesign and improved outcomes, the paper poses the hypothesis that centralisation might also reduce mortality for the much larger remainder cohort of undifferentiated and unselected emergency presentations.The researchers have taken the opportunity to study this possibility by examining the mortality consequences observed following the replacement of three District General Hospital (DGH) EDs with a single large specialist emergency centre.The ‘control group’ are the patients who attended the three DGH EDs at North Tyneside, Wansbeck and Hexham hospitals between June 2014 and June 2015. The ‘intervention’ group are the patients who attended the new single-site Northumbria … ER -
