Improved asthma outcomes among at-risk children in a pharmacist-led, interdisciplinary school-based health clinic: A pilot study of the CAReS program

Abstract

BackgroundDisparities in access to care and outcomes have been identified among children with asthma living in underserved communities. The Caring for Asthma in our Region’s Schoolchildren program was established to reduce disparities by providing school-based, comprehensive asthma care by a pharmacist-led, interdisciplinary team to high-risk pediatric populations in the Greater Pittsburgh area. ObjectiveTo investigate program impact on follow-up appointment attendance, delivery of guideline-based care, asthma control, asthma morbidity (emergency department [ED] visits, oral corticosteroid [OCS] requirement), and asthma-related knowledge and quality of life. MethodsThe study enrolled 50 children with asthma from 6 elementary schools (September 2014-December 2017). Children completed 5 visits over a 3-month period. McNemar’s test assessed improvement in guideline-based controller therapy use and reduced morbidity (ED visits or OCS requirement). Generalized estimating equation analyses determined the significance of monthly improvements in asthma control, asthma knowledge, and quality of life. ResultsA 100% show rate was achieved in nearly all participants (92.0%). Most of the patients were African-American (56%). In children with persistent disease, only 21.4% were prescribed controller therapy at baseline, which improved to 78.5% upon enrollment (P < 0.05). Asthma control statistically significantly improved (P < 0.05), and a reduction in percentage of patients who required an ED visit or an OCS burst pre-to postintervention was also statistically significant (31.3% vs. 14.6%, P < 0.05). The goal of 100% treatment plan knowledge was achieved in 67% of caregivers within 1 month and increased from 6% to 60% in children over 3 months (P < 0.05). Asthma-related quality of life also improved statistically significantly pre-to postintervention (P < 0.05). ConclusionsDisparities in asthma outcomes owing to inadequate access to health care can be addressed. Improved asthma control, asthma medication knowledge, quality of life, and reduced morbidity in high-risk pediatric patients are achievable as demonstrated by our study. Our findings support the feasibility and value of a pharmacist-led, interdisciplinary school-based health care delivery model in providing comprehensive asthma care to at-risk pediatric populations.
