Skin status for predicting pressure ulcer development: A systematic review and meta-analyses

There is low-certainty evidence that people with non-blanchable erythema may be more likely to develop new pressure ulcers than those without non-blanchable erythema. The evidence for the prognostic effects of other skin descriptors (e.g., history of pressure ulcer) is of very low-certainty. The findings support regular skin assessment and preventive action being taken in the presence of non-blanchable erythema. Given the millions at risk of ulceration and the widely recommended use of skin status as part of risk assessment there is a need for more, high quality confirmatory studies.
