Pressure ulcer prevention and treatment. A synopsis of the current evidence from research

Foam alternatives to the standard hospital foam mattress can reduce the incidence of pressure ulcers in people at risk. The relative merits of AP and CLP devices and of the different AP devices for pressure ulcer prevention are unclear. There is some evidence from one study to suggest that LAL beds may reduce the incidence of pressure ulcers compared with standard intensive care beds. There is insufficient evidence to make conclusions on the value of various CLP devices and sheepskins as pressure ulcer prevention strategies, although Australian Medical Sheepskin was an effective preventive strategy in a recent study. There is evidence from two trials that air-fluidized therapy may improve pressure ulcer healing rates. There is insufficient evidence to make conclusions on the value of other beds and mattresses as pressure ulcer treatments. There is insufficient evidence to recommend any particular wound dressing or debridement technique. Research about pressure ulcer prevention and treatment is generally conducted on a small scale and is of poor quality; few economic evaluations have been undertaken of pressure area care strategies. Only when a clinically relevant research agenda has been developed and appropriate research methods have been used in sufficiently large studies can evidence-based pressure ulcer prevention and treatment be a possibility. Until then, nurses and other health care professionals can only rely on what little research evidence exists together with their professional judgment to make decisions in this field.
