This study estimated the paediatric ED AE rate to be 3% of visits. In adult cohorts, AE reviews based on a broader trigger methodology have identified AE rates of 8%.7 One meta-analysis of mixed paediatric and adult populations by Stang et al found the range of AEs attributable to ED care to be 0.2%-6.0%.8 The wide range of AE rates in earlier studies highlights how decisions about the method of detection of AEs may influence reported rates. For example, the lower bound of 0.2% reported in Stang's analysis was based on voluntary error reports, which are known to severely underestimate AEs.
