Characteristics of hip fracture patients with and without muscle atrophy/weakness: Predictors of negative economic outcomes
2015
AbstractObjective:Hip fractures have negative humanistic and economic consequences. Predictors and sub-groups of negative post-fracture outcomes (high costs and extensive healthcare utilization) were identified in patients with and without muscle atrophy/weakness (MAW).Methods:Truven Health MarketScan data identified patients ≥50 years old with inpatient hospitalizations for hip fracture. Patients had ≥12 months of continuous healthcare insurance prior to and following index hospitalization and no hip fracture diagnoses between 7 days and 1 year prior to admission. Predictors and sub-groups of negative outcomes were identified via multiple logistic regression analyses and classification and regression tree (CART) analyses, respectively.Results:Post-fracture 1-year all-cause healthcare costs (USD$31,430) were higher than costs for the prior year ($18,091; p < 0.0001). Patients with MAW had greater post-fracture healthcare utilization and costs than those without MAW (p < 0.05). Greater post-fracture costs ...
