Biochemical markers may improve accuracy of pressure ulcer risk assessment

Study calls for more research into use of biochemical markers to improve inadequate pressure ulcer risk assessment

The accuracy of predicting a pressure ulcer using the Waterlow, Braden or Norton score are little more than chance according to a paper published in the Journal of Tissue Viability.

The author suggests that adding biochemical markers, such as albumin, to risk assessment screening may improve accuracy. However a large clinical trail is needed to explore whether observational risk assessment combined with biochemical markers can improve pressure ulcer prevention.

The cost of measuring biochemical markers should also be evaluated as it may be more appropriate to provide more pressure relieving equipment.
