Abstract

Medical record review (MRR) studies have been reported to make up 25% of all scientific studies published in emergency medical (EM) journals. However, unlike other study designs, there are no standards for reporting MRRs and very little literature on the methodology for conducting them. The purpose of this article is to provide the reader with methodological guidance regarding the strengths and weaknesses of these types of studies.
