A patient-centered telephone intervention using the asthma action plan.

Background And Objectives: Application of the patient-centered medical home (PCMH) practice model requires managing patients with chronic diseases, such as asthma, with patient-centered approaches that ensure appropriate ongoing assessment and treatment for all patients. The Asthma Control Score (ACS) and the Asthma Action Plan (AAP) are validated tools for assessment and management of asthma. ACS use by phone has been shown to accurately assess patients' asthma control; however, no studies to date demonstrate the utility of AAP implementation by phone to improve asthma control.
