AbstractIn 2019, a landmark change was made to the Global Initiative for Asthma (GINA) guidelines in which an as-needed low-dose inhaled corticosteroid (ICS)-formoterol inhaler was updated to be the preferred reliever therapy for all asthma patients. Use of short-acting beta-agonist monotherapy is no longer recommended. The purpose of this study was to assess provider adherence with the GINA guidelines in regards to reliever therapy. This was a retrospective cohort study of patients presenting with an acute asthma exacerbation from January to May of 2020 and 2021. The primary objective of this study was to quantify provider adherence with the GINA guidelines in terms of reliever therapy. Preferred reliever therapy was defined as use of an as-needed low-dose ICS-formoterol combination inhaler. Alternative reliever therapy was defined as use of a SABA inhaler with ICS-containing controller therapy. Secondary objectives included the number of patients discharged on any form of corticosteroid and the number of patients who may have been ideal candidates for transition to preferred reliever therapy. A total of 127 patients were included in the analyses. Upon hospital discharge, three patients (2.4%) received preferred reliever therapy and 97 (76.4%) received alternative reliever therapy. Rates of recommended reliever therapy prescription increased from 55 to 79% upon hospital discharge (p < 0.001). Prescription of GINA guideline-recommended reliever therapy was 79% within the patient population evaluated; however, rates significantly improved following hospitalization for asthma exacerbation. Additional studies that assess barriers to guideline adherence may be recommended.© 2023. The Author(s), under exclusive licence to Società Italiana di Medicina Interna (SIMI).
