Barriers to Implementation of SMART: Views From Pediatric Asthma Specialists.

BACKGROUND

The Global Initiative for Asthma (GINA) and National Asthma Education and Prevention Program (NAEPP) both recommend a combination inhaled corticosteroid (ICS)/formoterol inhaler to replace short-acting beta-agonists (SABA) as the preferred reliever therapy for Steps 3 and 4 of their asthma treatment strategies (known as Single Maintenance and Reliever Therapy or SMART). The extent of adoption and factors influencing use among pediatric asthma specialists remain unclear.

OBJECTIVE

To gain a better understanding of SMART prescribing practices and factors that facilitate or impede its use in the United States among pediatric asthma specialists.

METHODS

An electronic survey on SMART knowledge and practices was distributed to pediatric pulmonology division directors for dissemination to pediatric asthma specialists in allergy and pulmonology divisions.

RESULTS

Sixty-eight completed survey responses were received between March and October of 2024. All asthma specialists were familiar with SMART, and over 90% were comfortable with its implementation in pediatric asthma. However, there was wide variability in the percentage of patients advised to use their prescribed maintenance ICS/formoterol inhaler as a reliever that did not correlate with the comfort level of the clinician or years in clinical practice, but did correlate with the region of practice.

CONCLUSIONS

Despite GINA/NAEPP recommending SMART, there is substantial variation in its implementation among pediatric asthma specialists. Survey results indicate that pediatric asthma specialists are comfortable with its use, but that improvement in EMR efficiency and consistent insurance coverage are needed to increase SMART adoption.
