Hanskamp-Sebregts M, Zegers M, Vincent C, van Gurp PJ, de Vet HCW, Wollersheim H. BMJ Open. 2016;6:e011078.

Detection of safety hazards remains a challenge. This systematic review examined record review as a way to identify adverse events. Consistency of event identification was adequate, but data are lacking regarding validity of medical record review compared to other safety assessment methods, such as direct observation of patient care. The authors recommend formal validation of record review as a method to detect adverse events.
