Frequency and impact of active clinical issues and new impairments on hospital discharge in patients with hip fracture.

Abstract
HIP FRACTURES are common, costly, and clinically serious. Approximately 350 000 hip fractures occur annually in the United States, accounting for nearly $6 billion per year in hospital costs.1 Most patients who fracture their hips are elderly and frail and are at high risk for death, medical complications, and loss of function.2-4 Because most patients often have numerous underlying comorbid illnesses, the risk of developing cardiopulmonary, thromboembolic, infectious, urologic, and neurologic complications is substantial.5
