Abstract
Background
Asthma is a treatable chronic disease of airway inflammation with varying levels of control and severity. Biological therapy is an effective evidence-based treatment for patients with allergic and eosinophilic phenotypes of asthma who are classified as poorly controlled moderate to severe asthma. Yet, evidence-based treatments are infrequently used to support effective care of poorly controlled moderate and severe asthma. This quality improvement (QI) project aimed to increase the number of patients with uncontrolled moderate to severe asthma at an outpatient asthma center who are screened and referred for biologic therapy when appropriate.
Methods
A guideline-based biologic screening protocol was implemented using plan-do-study-act (PDSA) methodology allowing for a systematic approach for implementation, monitoring and making adjustments. A pre- and post-independent groups comparative design was utilized to evaluate screening and referral data.
Results
Screening improved significantly from pre- (n = 30, 23.8%) to post-implementation (n = 17, 70.8%), p < 0.001; phi = .372. Referrals to biologics also improved from 42.4% (n = 28) to 93.3% (n = 14), p < 0.001; phi = .396. Providers reported increased knowledge, confidence, and satisfaction with the asthma screening protocol at post-implementation.
Conclusions
The implementation of an asthma screening protocol for asthma patients in an ambulatory center is an effective way of increasing screening for eligibility for biologic therapy. Adhering to the standard of care based on evidence-based guidelines increased access to biologic therapy with a higher percentage of patients being referred for therapy.
