Patients enrolled in a specialized interdisciplinary Asthma Care Network (ACN) experienced significantly fewer emergency department visits and hospitalizations, highlighting the potential for team‑based care to transform asthma management.
That’s according to the paper, “Impact of an Interdisciplinary Asthma Care Network on Emergency Department Visits and Hospitalizations,” recently published in the Journal of Asthma and Allergy.
The research followed 1,248 patients in Southeastern Ontario, Canada, who were enrolled in the ACN between 2009 and 2018. The interdisciplinary care these patients received was compared to 3,629 matched patients who received standard care. Despite entering the network with more severe asthma and higher pre‑enrollment emergency visits, ACN participants saw substantial improvements after joining the program.
According to the study, 21% of ACN patients experienced reduced emergency department visits, compared with 6.7% of those not enrolled in the program. Hospitalizations showed an even more dramatic difference: Slightly more than 10% of ACN patients had fewer hospital stays, while only 1.4% of the comparison group saw similar reductions.
The study’s authors suggested the results show that even patients with more complex asthma can achieve better outcomes when they receive coordinated, guideline‑driven care.
The ACN brings together respirologists, nurse practitioners, educators and primary care support to deliver evidence‑based asthma care. Patients receive objective monitoring, personalized action plans and structured follow-up after acute episodes — services that traditional primary care settings often lack.
In adults, the program was especially effective. After controlling for severity and comorbidities, enrolled adults no longer experienced higher rates of acute care use than non‑ACN patients, despite starting from a worse baseline. Pediatric patients, while still showing benefits, continued to require more emergency care than their counterparts — possibly reflecting the need for longer-term management or more complex disease patterns in children.
Researchers said the findings add to growing evidence that interdisciplinary management can meaningfully reduce the burden of chronic respiratory disease. Previous research has shown that asthma education alone can cut emergency visits by 31% and hospitalizations by more than half. This study reinforces that more structured, integrated networks can amplify those gains, the authors noted.
Additionally, researchers said the study’s Ontario participants represent a geographic area with historically low rates of specialist follow-up — especially after emergency visits — which may contribute to avoidable exacerbations. The ACN’s centralized, coordinated structure appears to address this gap.
Although the study relied on data up to 2018, before the widespread adoption of new biologic therapies, the authors said the ACN model is highly adaptable. They proposed future enhancements such as digital self-management tools and artificial intelligence (AI)-driven monitoring to further support patients between clinic visits.
