Isolated Hip Fractures in the Elderly: Best Practice Analysis of Perioperative Medical Optimization Including Effect of Comorbidities, Functional Status, and Demographics

Abstract

Isolated hip fractures (IHFs) contribute to functional decline in the elderly. Our purpose was to evaluate IHF at two level 1 trauma centers and the effect of comorbidities on length of stay (LOS), ICU admission, disposition, and mortality. A retrospective study from July 2016 through December 2020 including patients ≥65 with IHFs identified 785 patients. Prior dependent functional status yielded a longer LOS (>6 days vs <6 days, P = .01). Comorbidities were not associated with increased LOS or ICU admission. ICU admission rate was 12.75%. Patients with advanced directive had increased ICU admission (8% vs 3%). The mortality rate was 2%. Increased mortality was seen with advanced directives (17% vs 2%, P < .05) and cirrhosis/substance abuse (12% vs 2%, P < .05). Disposition included home (20%), rehabilitation (43%), and SNF (31%). Comorbidities did not affect ICU admission, LOS, or disposition; however, cirrhosis/substance abuse demonstrated increased mortality.
