The 1-year mortality of patients treated in a hip fracture program for elders

Geriatr Orthop Surg Rehabil. 2010 Sep;1(1):6-14. doi: 10.1177/2151458510378105.


Comanagement of geriatric hip fracture patients with standardized protocols has been shown to improve short-term outcomes after surgery. A standardized, patient-centered, comanaged Hip Fracture Program for Elders is examined for 1-year mortality. Patients ≥60 years of age who were treated in the Hip Fracture Program for Elders were comanaged by orthopaedic surgeons and geriatricians. Data including age, place of origin, procedure, length of stay, 1-year mortality, Charlson score, and activities of daily living (ADLs) were retrospectively collected. A total of 758 patients ≥60 years of age with hip fractures between April 15, 2005, and March 1, 2009, were included. Their data were analyzed, and the Social Security Death Index and the hospital data system were searched for mortality data. Seventy-eight percent were female, with a mean age of 84.8 years. The mean Charlson score was 3. Fifty percent were admitted from an institutional setting. The overall 1-year mortality was 21.2%. Age (odds ratio [OR] = 1.03, 95% confidence interval [CI] = 1.00-1.05; P = .02), male gender (OR = 1.55, 95% CI = 1.01-2.36; P = .04), low Parker mobility score (OR = 2.94, 95% CI = 1.31-6.57; P = .01), and a Charlson score of 4 or greater (OR = 2.15, 95% CI = 1.30-3.55; P = .002) were predictive of 1-year mortality. ADL dependence was a borderline predictor, as was medium Parker mobility score. Prefracture residence and moderate comorbidity (Charlson score of 2-3) were not independently predictive of mortality at 1 year after adjusting for other characteristics. A comprehensive comanaged hip fracture program for elders not only improves the short-term outcomes but also demonstrates a low 1-year mortality rate, particularly in patients from nursing facilities.
