Pressure ulcer prophylaxis in elderly patients using polyurethane foam or Jay wheelchair cushions.
A significantly lower proportion of the patients in the Jay group (25%) experienced pressure ulcer formation during the three months of observation as compared to the foam group (41%). No statistically significant differences were found between groups on the location, severity, or healing duration of the pressure ulcers. Most lesions (65%) were limited to persistent erythema of intact skin, and healed in three to four weeks. Significantly higher proportions of patients in the Jay groups (7%) rejected their cushion because of discomfort as compared to foam (1%). The incidence of pressure ulcers was significantly higher among those patients who experienced peak interface pressures recorded at 60 mmHg or higher, had low Norton scores (< or = 11), or were malnourished.
