The Radiology Events Register (RaER)

Abstract

A systematic review has shown that 9.2% of hospital inpatients experience harm from their care, with a median percentage of preventability of 43.5% (De Vries et al. 2008). Over half (56.3%) of patients experienced no or minor disability, whereas 7.4% of events were lethal. Operation- (39.6%) and medication-related (15.1%) events were most prevalent (De Vries et al. 2008). Many more patients are subject to near misses, with estimates ranging from 3 to 300 times as many near misses as adverse events (Barach and Small 2000; Runciman et al. 2007).
