Reducing pressure ulcer incidence in a long-term setting.

Hampton S, Collins F.

Selection of appropriate pressure prevention equipment relies on risk assessment and clinical assessment of the resident/patient. Decisions are then made in combination with manufacturer's recommendations, such as interface pressure testing. However, risk assessments can over-predict and laboratory investigations do not necessarily provide an accurate picture of how individual patients will react to pressures from support services. There are few studies on visco-elastic mattresses and their benefits in reducing pressure ulcer incidence. Therefore, a small study was undertaken to review the efficacy of a pressure-reducing visco-elastic foam mattress. For the benefit of the study, a 20-bedded nursing home was provided with 20 visco-elastic mattresses (Pressurease) and 20 pressure-reducing cushions (Mediform Visco). The study aimed to demonstrate a reduction in pressure ulcer prevalence. The study involved 21 residents over a 6-month period. There was a 58.3% prevalence (of Stirling grade 1-2 pressure damage) at trial initiation. The results showed an 85.7% decrease of pressure ulcers within 4 weeks, and an overall decrease of 82.5% over the 6-month period. Comfort levels, scored by residents on a visual analogue scale, demonstrated the Pressurease mattress to be superior to the nursing home standard mattress.
