Can one accurately date a bruise? State of the science

Forensic nursing experts and other health professionals often testify regarding the injuries women and men receive from violence. Bruise discoloration can provide an opportunity for health professionals to grossly estimate the age of impact and determine if it is consistent with a given reported history. However, there is much confusion in the literature and clinical practice as to the accuracy of dating bruises. This article will demonstrate that using the color of the bruise as the primary criteria to determine its age is not the best practice. The limited available research and related literature on the topic are flawed and inconsistent. Finally, recommendations will be made for future research and clinical practice.
