Prospective evaluation of health-related quality of life in geriatric trauma patients

Abstract

Background: Frailty is an established predictor of adverse outcomes in geriatric patients. Health-related quality of life (HRQoL) is an important outcome measure among trauma patients. This prospective observational study examined the impact of frailty on health-related quality of life in geriatric trauma patients.

Methods: We prospectively enrolled geriatric (age ≥65 years) trauma patients. We calculated the frailty index (FI) within 24 hours of admission using the trauma-specific frailty index. Patients were stratified into frail (frailty index ≥0.27) and nonfrail (frailty index <0.27). Health-related quality of life was calculated at discharge and at 30 days (day) after discharge using the RAND Short Form-36 (SF-36). Outcome measures were health-related quality of life at discharge, 30-days postdischarge, and delta health-related quality of life. Regression analysis was performed to control for demographic, vital signs, and injury parameters.

Results: We enrolled 296 patients. The mean age was 75.1 ± 9.8 years, 59% were male, and 81% were white. Frail patients accounted for 34%, and they had a lower health-related quality of life at discharge (366 vs 548, P < .01) and at 30-day postdischarge (393 vs 744, P < .01). Nonfrail patients scored higher in 6 out of 8 domains of health-related quality of life. Nonfrail patients had improved delta health-related quality of life (P < .01), unlike frail patients (P = .11). A linear regression model revealed an inverse relationship between frailty and improvement in health-related quality of life over 30-day postdischarge (β = -0.689, [confidence interval, -0.963 to -0.329] P = .01). This association remained statistically significant after controlling for potential confounding covariates, such as age, sex, race, and injury severity.

Conclusion: Compared with nonfrail geriatric trauma patients, those who were frail had poor health-related quality of life at discharge and at 30-day postdischarge. Frailty negatively affects the recovery of health-related quality of life after trauma. The use of frailty indices may help identify and develop targeted interventions to improve health-related quality of life among geriatric trauma patients.
