Frailty index and risk of pressure injuries in nursing home residents: results from the KASEHPAD cohort
Abstract
Frailty is highly prevalent among institutionalized older adults and may exacerbate vulnerability to pressure injuries. Despite its clinical relevance, the prognostic value of frailty for pressure injuries risk in nursing home residents remains insufficiently characterized. To determine the relationship between the FI, measured by the Frailty Index (FI), and the risk of pressure injuries in a population of very complex older adults living in Caribbean nursing homes. Data are from the KASEHPAD (Karukera Study on Aging in Nursing Homes) study, a prospective, longitudinal study conducted in six nursing homes in Martinique and Guadeloupe. The FI was calculated at baseline using a 31-item deficit accumulation model (score range: 0-1). The association between FI and pressure injuries risk was examined using logistic regression models, with and without adjustment for age and sex. The study sample consisted of 332 individuals with a mean age of 81.3 years (standard deviation, SD, 10.1), of whom 50.6% were male. The mean FI score was 0.28 ± 0.14. Among the participants, 111 (33.4%) were identified as having a moderate to high risk of pressure ulcers. FI was strongly correlated with pressure ulcer risk (r = - 0·64; p < 0·001). Participants with an FI > 0·40 had markedly increased odds of pressure injuries risk (age- and sex-adjusted OR 24·1, 95% CI 11·7-52·7, p < 0.001). Frailty was independently and strongly associated with pressure injuries risk among nursing home residents. Routine assessment of frailty should be integrated into geriatric care to facilitate early identification of individuals at heightened risk and to inform preventive interventions. Such an approach could substantially reduce the clinical and economic burden of pressure injuries in this vulnerable population.
