Expert Consensus on SABA Use for Asthma Clinical Decision-Making: A Delphi Approach.

Purpose of Review: A modified Delphi process was undertaken to provide a US expert-led consensus to guide clinical action on short-acting beta₂-agonist (SABA) use. This comprised an online survey (Phase 1), forum discussion and statement development (Phase 2), and statement adjudication (Phase 3). Recent Findings: In Phase 1 (n = 100 clinicians), 12% routinely provided patients with ≥4 SABA prescriptions/year, 73% solicited SABA use frequency at every patient visit, and 21% did not consult asthma guidelines/expert reports. Phase 3 experts (n = 8) reached consensus (median Likert score, interquartile range) that use of ≥3 SABA canisters/year is associated with increased risk of exacerbation and asthma-related death (5, 4.75–5); SABA use history should be solicited at every patient visit (5, 4.75–5); usage patterns over time, not absolute thresholds, should guide response to SABA overuse (5, 4.5–5). Summary: Future asthma guidelines should include clear recommendations regarding SABA usage, using expert-led thresholds for action. [ABSTRACT FROM AUTHOR]
