Chronic wounds represent a worldwide problem. For laboratory and clinical research to adequately address this problem, a common language needs to exist.
This language should include a system of wound classification, a lexicon of wound descriptors, and a description of the processes that are likely to affect wound healing and wound healing end points.
The report that follows defines wound, acute wound, chronic wound, healing and forms of healing, wound assessment, wound extent, wound burden, and wound severity. The utility of these definitions is demonstrated as they relate to the healing of a skin wound, but these definitions are broadly applicable to all wounds.(Arch Dermatol. 1994;130:489-493)
