Predictors of Mortality in Elder Patients With Proximal Humeral Fracture.

In a cohort of elderly patients with fractures of the proximal humerus, patient characteristics including comorbidities, ASA classification, and lower BMI were associated with increased mortality. Specifically, those admitted at the time of fracture and treated nonoperatively had the highest mortality rate and, likely, represent the frailest cohort. Those initially treated as outpatients and later treated operatively had the lowest mortality and, likely, represent the healthiest cohort. These data are inherently biased by prefracture comorbidities but help stratify our patients' mortality risk at the time of injury.
