Pressure ulcers (PU) are a significant healthcare problem for the growing number of United States (US) elderly long-term care (LTC) residents. PU diminish quality of life, exact a devastating loss of function, increase the risk of death in geriatric populations and raise healthcare costs. Despite Federal preventive mandates for the long-term care (LTC) setting, widespread non-compliance occurs. The last three Centers for Medicare and Medicaid Services (CMS) LTC surveys showed a cumulative increase of 21% in the number of citations issued for failure to provide proper intervention to prevent or treat pressure ulcers. Costs for the management of PU in the US likely exceed $6.4 billion annually, with a prevalence of approximately 28% in the LTC population. Estimates of the prevalence of sitting-acquired PU in the elderly, at-risk population range from 36-50%. Several studies, including our own pilot investigation, support these estimates and have suggested that the use of wheelchair cushions designed to reduce interface pressure will reduce the incidence of sitting-acquired PU. Despite this evidence, elderly wheelchair users are not routinely evaluated for seating and positioning needs because definitive studies have not been completed to justify funding for such seating interventions. Consequently, elderly Medicare beneficiaries are being denied access to medically necessary and clinically appropriate interventions. Instead, they are most frequently provided with convoluted or segmented-foam cushions that are not designed for pressure ulcer prevention. The primary aim of the proposed multi-center, randomized pressure-reducing wheelchair cushion trial (PRWC-II) is to determine the efficacy of pressure-reducing cushions in preventing sitting-acquired pressure ulcers in the elderly, LTC population. Positive results of the proposed trial will provide the level of evidence needed to change the standard of care to include the routine evaluation of at-risk residents for seating and positioning needs and the provision of a pressure-reducing cushion as a preventive measure against sitting acquired pressure ulcers. If our hypothesis is correct, such an intervention should result in a decrease in the incidence and prevalence of sitting-acquired pressure ulcers, reduced healthcare costs, and improved quality of life.
