Each year, more than 1.3 million individuals visit U.S. emergency departments (EDs) with asthma-related conditions.1 Patients often present after being unable to manage their condition at home. Historically, short-acting beta agonists (SABAs), such as albuterol, have been used as a pillar of acute asthma management. These bronchodilators provide quick relief. For patients well enough to be discharged from the ED, emergency physicians generally ensure patients have access to an albuterol rescue inhaler and often prescribe a short course of steroids; however, this is not the best practice.

ACEP Now: Vol 44 – No 01 – January 2025Shift in Guidance
Guidelines have been shifting during the past several years with regard to two specific medications—inhaled corticosteroids (ICS) and long-acting beta agonists (LABAs)—and now recommend ICS, which treat airway inflammation, as a part of rescue therapy. In fact, professional society recommendations cite overuse of SABAs and underuse of ICS inhalers as significant contributing factors to asthma morbidity.
For years, ICS inhalers containing fluticasone or budesonide have been a part of longterm treatment of persistent asthma due to their effect on inflammation and a substantially reduced risk for potential side effects compared with oral corticosteroids. In 2007, guidelines from the National Asthma Education and Prevention Program suggested that there may be a role for ICS, even if used intermittently. Moreover, the guidelines called out emergency clinicians specifically, recommending we should “consider initiating an ICS at discharge, in addition to oral systemic corticosteroids (Evidence B).”2 In a 2020 update of the 2007 guidelines, ICS were recommended as a part of every treatment pathway with the exception of mild intermittent asthma, a category that some guidelines have eliminated altogether.3,4
A recently published systematic review and network meta-analysis of 50,496 adult and pediatric patients from 27 randomized trials provided the overwhelming case for clinicians to ensure that patients with asthma are prescribed ICS.5 Network meta-analyses allow for comparison of outcomes among treatment groups where direct comparisons are limited or do not exist. This study found that inhalers containing ICS were associated with fewer severe exacerbations (i.e., had fewer systemic corticosteroids, ED visits, and/or hospitalizations) compared with SABAs alone. The risk ratio for ICS-formoterol was 0.63 (95 percent CI, 0.60-0.72) and was 0.84 (95 percent CI, 0.73-0.95) for ICS–SABA. ICS–formoterol therapy was associated with fewer asthma-related hospitalizations compared with SABAs, even when combined with ICS. No signal of increased harm resulted from either type of ICS therapy.5 The evidence is clear: We need to move away from SABA therapy alone.
