Evaluation of a disease-state education program in asthma: Application of the Knowledge-to-Action Framework.

Abstract

Background: In patients with asthma, bronchoconstriction and airway inflammation both contribute to airway narrowing and airflow limitations, which lead to symptoms and exacerbations. Short-acting beta 2-agonist (SABA)-only rescue therapy addresses only bronchoconstriction and is associated with increased morbidity and mortality. Current asthma management guidelines recommend concomitant treatment of symptoms and inflammation with a fast-acting bronchodilator and inhaled corticosteroid (ICS) as rescue therapy for patients 12 years of age. However, there is an education and outreach gap for the wider adoption of anti-inflammatory rescue therapy in clinical practice.

Objective: AstraZeneca has developed an education program for health-care practitioners (HCPs) based on a Knowledge-to-Action Framework, with the aim of increasing HCPs' understanding of key disease-state concepts related to evidence-basedmanagement of asthma.

Methods: A multichannel, evidence-based education program was presented at medical conferences across the United States between December 2022 and December 2023. Before and after each event, attendees were asked to complete a survey that rated their agreement with six disease-state concepts on a five-point Likert scale. These concepts related to the role of airway inflammation, fluctuations in inflammation, SABA and ICS therapy, and the risk of exacerbations.Postevent responses to the survey were assessed relative to pre-event responses and longitudinally over 12 months by using calculated odds ratios and 95% confidence intervals. Acceptance and/or understanding of a concept was defined as a rating of "agree" or "strongly agree" from at least 80% of respondents.

Results: The proportion of respondents who agreed or strongly agreed with each concept was significantly higher postevent versus pre-event (p < 0.001). The 80% acceptance and/or understanding threshold was surpassed for all concepts after the event.

Conclusion: The medical education program improved understanding and/or acceptance of key disease-state concepts related to asthma management among participating HCPs. Effective communication of disease management concepts may lead to improved patient health outcomes through more rapid acceptance of guideline-recommended medical therapies.
