Adverse events in patients with return emergency department visits.
Calder L, Pozgay A, Riff S, et al. BMJ Qual Saf. 2014 Dec 24; [Epub ahead of print].
This observational study examined all return emergency department visits within 7 days of an initial visit to determine if the second visit was caused by an adverse event. An adverse event was present in 12% of return visits that occurred within 72 hours of the initial visit. The authors suggest that this utilization pattern may be a promising trigger tool to identify adverse events.
