Risk factors for pressure ulcer development in institutionalized elderly.

This study aimed to analyze the risk factors for the development of Pressure Ulcers (PU) in old people living in Long Staying Institutions. It is a prospective and cohort study carried out in four Institutions. A total of 94 old people composed the sample and were assessed during three consecutive months. The total scores of the Braden Scale were different between the groups with and without PU, at the first (p=0.030) and last assessments (p=0.001); humidity, nutrition and friction/shearing were significantly different between those with and without PU, and were always worst among the first. Female gender and previous PU were confirmed as predictive for the development of PU (r(2)=0.311).
