A Cross-Sectional Study on Prescription Patterns of Short-Acting β

Purpose: Overuse of short-acting β Patients and Methods: This observational, cross-sectional cohort study of SABINA III included patients (aged ≥12 years) with asthma recruited from seven sites in Colombia. Demographics, disease characteristics (including investigator-defined asthma severity guided by the 2017 Global Initiative for Asthma report), and asthma treatments prescribed (including SABAs and inhaled corticosteroids [ICS]) in the 12 months preceding the study were recorded using electronic case report forms during a single study visit. Results: Of 250 patients analyzed, 50.4%, 33.2%, and 16.4% were enrolled by pulmonologists, general medicine practitioners, and allergists, respectively. Most patients were female (74.0%) and had moderate-to-severe asthma (67.6%). Asthma was partly controlled or uncontrolled in 57.6% of patients, with 15.6% experiencing ≥1 severe exacerbation 12 months before the study visit. In total, 4.0% of patients were prescribed SABA monotherapy and 55.6%, SABA in addition to maintenance therapy. Overall, 39.2% of patients were prescribed ≥3 SABA canisters in the 12 months before the study visit; 25.2% were prescribed ≥10 canisters. Additionally, 17.6% of patients purchased SABAs over the counter, of whom 43.2% purchased ≥3 canisters. Maintenance medication in the form of ICS or ICS/long-acting β Conclusion: Our findings suggest that prescription/purchase of ≥3 SABA canisters were common in Colombia, highlighting a public health concern. There is a need to improve asthma care by aligning clinical practices with the latest evidence-based treatment recommendations to improve asthma management across Colombia.
