Cost effectiveness of an air-inflated static overlay for pressure ulcer prevention: a randomized, controlled trial.

Unlabelled:  Numerous pressure-relieving surfaces of varying costs are available for the prevention of pressure ulcers. There is insufficient evidence to draw conclusions regarding the efficacy or merits of using more expensive technologies. The purpose of this unblinded, randomized, prospective study was to compare the clinical and the cost effectiveness of an inflated overlay with rented, pressure-relieving surfaces for the prevention of pressure ulcers.
