Abstract

Introduction: Many geriatric hip fracture patients utilize significant healthcare resources and require an extensive recovery period after surgery. There is an increasing awareness that measuring frailty in geriatric patients may be useful in predicting mortality and perioperative complications and may be useful in helping guide treatment decisions. The primary purpose of the study is to investigate whether the frailty index predicts discharge disposition from the hospital and discharge facility and length of stay.

Methods: In this retrospective cohort study, patients aged 65 years and older presenting to a level 1 trauma center with a hip fracture and a calculated frailty index were eligible for inclusion. The primary outcome was discharge disposition. Secondary outcomes were hospital and discharge facility length of stay, 90-day hospital mortality and readmissions, and return to home.

Results: A total of 313 patients were included. The frailty index was a robust predictor of discharge to a skilled nursing facility (OR 1.440 per 0.1 point increase). Patients with a higher frailty index were at higher risk of 90-day mortality and less likely to return to home at the end of follow-up. There was a very weak correlation between the frailty index and hospital length of stay (ρ=0.30) and rehab length of stay (ρ=0.26).

Conclusion: The frailty index can be used to predict discharge destination from both the hospital and rehabilitation facility, 90-day mortality, and return to home after rehabilitation. In this study, the frailty index had a very weak correlation with length of stay in the hospital and in discharge destination. The frailty index can be used to help guide medical decision making, goals of care discussions, and to determine which patients benefit from intensive rehabilitation.
