Malnutrition in hospitalized patients can double the risk of developing pressure ulcers. In this Queensland, Australia, study, energy and protein intakes of 184 hospitalized patients with restricted mobility, and thus greater pressure ulcer risk, were tracked and studied. 55% and 47% ate less than 75% of the quantity that would meet their energy and protein requirements. Renal disease patients were five times more likely to be undernourished, but with supplementation only four times more likely. All patients with supplementation showed some improvement.
