BACKGROUND: Knowledge about expected recovery after hip fracture is essential to help patients and families set realistic expectations and plan for the future.

OBJECTIVES: To determine rates of functional recovery in older adults who sustained a hip fracture based on one's previous function.

DESIGN: Observational study.

PARTICIPANTS: We identified subjects who sustained a hip fracture while enrolled in the nationally representative Health and Retirement Study (HRS) using linked Medicare claims. HRS interviews subjects every 2 years. Using information from interviews collected during the interview preceding the fracture and the first interview 6 or more months after the fracture, we determined the proportion of subjects who returned to pre-fracture function.

MAIN MEASURES: Functional outcomes of interest were: (1) ADL dependency, (2) mobility, and (3) stair-climbing ability. We examined baseline characteristics associated with a return to: (1) ADL independence, (2) walking one block, and (3) climbing a flight of stairs.

KEY RESULTS: A total of 733 HRS subjects ≥65 years of age sustained a hip fracture (mean age 84 ± 7 years, 77 % female). Thirty-one percent returned to pre-fracture ADL function, 34 % to pre-fracture mobility function, and 41 % to pre-fracture climbing function. Among those who were ADL independent prior to fracture, 36 % returned to independence, 27 % survived but needed ADL assistance, and 37 % died. Return to ADL independence was less likely for those ≥85 years old (26 % vs. 44 %), with dementia (8 % vs. 39 %), and with a Charlson comorbidity score >2 (23 % vs. 44 %). Results were similar for those able to walk a block and for those able to climb a flight of stairs prior to fracture.

CONCLUSIONS: Recovery rates are low, even among those with higher levels of pre-fracture functional status, and are worse for patients who are older, cognitively impaired, and who have multiple comorbidities.
