The Role of Access and Cost-Effectiveness in Managing Asthma: A Systematic Review.

ABSTRACT

BACKGROUND: Inconsistent and unequal access to medical care is an issue that predates the COVID19 pandemic, which only worsened the problem. Limited access to care from asthma specialists and other specialists treating comorbid diseases may adversely affect asthma. OBJECTIVE: The purpose of this review is to identify health disparities associated with access to care for asthma, and cost-effectiveness of therapies and interventions addressing this health disparity. METHODS: A narrative systematic review was undertaken using MeSH searches of English language articles published in CINAHL, Scopus, or PubMed. RESULTS: A total of 725 articles were identified. Barriers recognized from the literature included access to diagnostic spirometry, access to specialists, medication formulary restrictions, and issues leading to medical nonadherence. Telemedicine, school-based health care interventions, digital applications, and non-office-based digital spirometry could be used to address these gaps in access to asthma care while potentially being cost-effective. CONCLUSION: With the widespread adoption of telemedicine because of the pandemic, and adoption of other mobile services, we now have potential tools that can increase access to asthma care, which can help address this health care inequity. Evidence is limited, but favorable, that some of these tools may be cost-effective.
