Pressure-related deep tissue injury under intact skin and the current pressure ulcer staging systems.
OBJECTIVE
To identify how current pressure ulcer staging systems and experts describe pressure-related deep tissue injury under intact skin in the published research literature.


METHODS
A systematic review of published English-language literature as of November 2002 with the words decubitus or pressure ulcer(s) in the title. Additional relevant articles were identified by National Pressure Ulcer Advisory Panel members and were included in the analysis. An expert commentary was developed by iterative review by the National Pressure Ulcer Advisory Panel members.


METHODS
Manuscripts were reviewed for staging systems cited or described, definitions of Stage I pressure ulcers, and descriptions or definitions of pressure-related deep tissue injury under intact skin.


RESULTS
Ninety-four relevant articles were identified. Seventy-three articles (78%) described a staging system, and 55 of 73 (75%) cited the staging definitions from Shea, the National Pressure Ulcer Advisory Panel, or the Agency for Health Care Policy and Research. The National Pressure Ulcer Advisory Panel's staging definitions were the most frequently cited overall. Twenty-three articles (25%) included some discussion that could be interpreted as relevant to the topic of pressure-related deep tissue injury under intact skin; however, no consistency in definitions of Stage I pressure ulcers or terminology for pressure-related deep tissue injury under intact skin was found.


CONCLUSIONS
Several pressure ulcer staging systems are frequently cited, but none define pressure-related deep tissue injury under intact skin. The National Pressure Ulcer Advisory Panel recommends using the terms "pressure-related deep tissue injury under intact skin" or "deep tissue injury under intact skin" for describing these lesions and encourages investigators to establish the epidemiology and natural history of these lesions.
