Emergency Room Visit Prevention for Older Patients with Parkinsonism in a Geriatric Clinic.

Background: Older persons with parkinsonism (PWP) are at high risk for hospitalization and adverse outcomes. Few effective strategies exist to prevent Emergency Department (ED) visits and hospitalization. The interdisciplinary Geriatrics Clinic for Parkinson's ("our clinic") was founded to address the complexity of parkinsonism in older patients, supported by a pharmacist-led telephone intervention (TI) service.
