An evaluation of approaches to asthma self-management education for adults: the AIR/Kaiser-Permanente Study

Abstract

The purpose of the AIR/Kaiser-Permanente asthma project is to evaluate various approaches to the education of adults with asthma, identifying those types of patients for whom particular approaches are most cost effective. Critical self-management practices for adults with asthma were identified using the critical incident technique. An individualized and a group administered educational program are being developed to teach the identified critical skills, using the instructional models previously employed in AIR WISE and AIR POWER programs for children with asthma. Three hundred patients with moderate to severe asthma from Northern California Kaiser-Permanente Medical Group clinics will participate in a trial of these programs. Patients will be randomly assigned to one of four conditions: One of two educational programs, an information/attention control, or a data-only control condition. Data will be collected on all patients for 15 months; health care utilization data covering a two-year period will be available from medical records. Program effectiveness will be evaluated in terms of pre-post changes in the patients' knowledge, attitudes, self-management practices, medical condition, daily functioning, and utilization of services. Cost effectiveness will be evaluated, paying specific attention to the cost effectiveness of different educational approaches for different types of patients.
