Evaluating Outcomes from an Integrated Health Service for Older Patients.

Background: Hospital-associated disability is the loss of the ability to complete one activity of daily living (ADL), with this decline occurring between the onset of acute illness and discharge from the hospital. Approximately 30% of patients who are >70 years old and admitted to hospitals are discharged with an ADL disability. Comprehensive geriatric assessment (CGA) models use a multidimensional, interdisciplinary process of diagnosis and treatment with the goal of improving outcomes and decreasing lengths of stay.
