Classification of dependence-related skin lesions: a new proposal.

A new theoretical framework on the development of pressure ulcers and other dependence-related lesions requires continued in-depth analysis of their conceptual bases. This study reports the historical background, definitions, and production mechanisms of these lesions, describing the differential pathognomonic features of pressure and/or shear ulcers, moisture-associated skin damage, and lesions from rubbing or friction. It also discusses the combined/multifactorial lesions that can be found in the clinical setting. Finally, it presents the new classification of these lesions proposed by the Spanish Pressure Ulcers and Chronic Wounds Advisory Panel.
