Abstract
Aim: Primary care physicians (PCPs), the first point of contact for most patients with asthma, exert a major influence on asthma care. To understand asthma medication prescription patterns in primary care globally, we describe the primary care cohort of SABINA III. Methods: In this cross-sectional study conducted in 24 low-to-high resourced countries, asthma patients (≥12 years) were recruited from March 2019–January 2020. Data on investigator-classified asthma severity (guided by 2017 Global Initiative for Asthma report), severe exacerbations, asthma symptom control and prescribed asthma treatments, including short-acting β2-agonists (SABA; ≥3 canisters associated with poor asthma outcomes1), during 12 months before the study visit were collected using electronic case report forms. Results: Of 8,351 patients analysed, 17.2% (n=1,440) were enrolled by PCPs and the rest by specialists. In primary care, 51.7% and 48.3% had mild and moderate-to-severe asthma, respectively. No medication reimbursement was reported for 35.5% of PCP-treated patients vs 27.3% overall. Overall, 45.4% experienced ≥1 severe exacerbation and among PCP-treated mild asthma patients, 39.0% and 13.7% had ≥1 and ≥3 severe exacerbations, respectively (Table). Uncontrolled/partly controlled asthma was observed in 58.3% of all PCP-treated patients and 57.2% of PCP-treated mild asthma patients. Among PCP-treated patients prescribed SABA monotherapy, 60.6% were prescribed ≥3 canisters (vs 53.6% overall) and 45.0%, ≥10 canisters (vs 29.9% overall). In addition to maintenance therapy, 69.0% of PCP-treated patients were prescribed ≥3 SABA canisters (vs 61.7% overall) and 38.2%, ≥10 canisters (vs 29.3% overall). Moreover, 21.5% of PCP-treated patients purchased SABAs over the counter (OTC); 40.5% purchased ≥3 canisters. Conclusion: High exacerbation burden and poor asthma control were observed in PCP-treated patients, even in those with “mild” asthma. SABA monotherapy prescriptions and OTC purchase of ≥3 canisters were substantial in primary care. Reducing SABA overreliance in primary care, per current evidence-based guidelines, may thus improve clinical outcomes.
