Background: Hospitalized older adults are 59.8 times more likely to develop disability than those who are not hospitalized. No studies have examined the effectiveness of Home Health (HH) physical therapy on improving function in older adults with multiple co-morbidities after hospitalization. Our goal is to enable older adults with multiple chronic conditions to recover function by providing adequate content and dose of intervention after hospitalization. This intervention is designed to work within the existing Medicare system and has potential for immediate clinical impact.
