Evaluation of Risk for Pressure Ulcers Using the Braden Scale in Elderly Patients Receiving Long-Term Care

Abstract

Background: Elderly patients receiving long-term care are at high risk for pressure ulcers. This study was done to identify histories of pressure ulcers and to evaluate the risk of pressure ulcers using the Braden scale. Methods: We enrolled 103 subjects receiving nursing homecare from a university hospital in Gyeongju or admitted to nursing homes in Pohang between April 1, 2010 and June 30, 2010. Assessment tools included demographic information, level of care, activities of daily living (ADL), presence of pressure ulcer, history of pressure ulcers and the Braden scale scores. Results: Twenty-six subjects (25.2%) had previous pressure ulcers. The mean Braden scale score was 15.02±4.23 (range, 6 to 23). And categorized into two groups based on previous pressure ulcers, the mean score was 11.92±3.59 for the group with previous pressure ulcers and 16.06±3.93 for the group without previous (p<0.001). The number of subjects with a risk for pressure ulcers according to the Braden scale was 71 (69.9%). The Braden scale had a positive correlation with level of care (p<0.001) and a negative correlation with ADL (p<0.001). Factors related to the history of pressure ulcers were homecare services (p=0.010), concurrent diabetes (p=0.023) and a low Braden scale score (p=0.028). Conclusion: We recommend that a pressure ulcer risk assessment be done routinely in elderly patients receiving longterm care services to minimize their occurrence.
