Scientific Poster Session III - Scoping Reviews

Abstract

Methods: The PRISMA-ScR guidelines were used to identify studies through PubMed, Embase, and CINAHL. A search strategy combined MeSH terms and keywords from a review of titles and abstracts. The review included English-language quantitative studies using CGM in low-income settings from inception to May 2024; studies had to have reported diabetes-related clinical outcomes in adults with type 2 diabetes. Studies in pregnant patients, meta-analyses, and systematic reviews were excluded. Two reviewers, using Covidence©, independently performed study selection, data extraction, and quality assessment.

Results: The review identified 1,176 studies, with 198 duplicates, resulting in 978 screened titles and abstracts. Forty-six studies underwent full text review, and 35 were excluded. Ultimately, 11 studies (5 abstracts, 5 manuscripts and 1 case study) met the review criteria. CGM use led to reductions in A1C levels across settings such as Federally Qualified Health Centers, clinics serving the underinsured, county health departments, and rural clinics. Other benefits included reduced hypoglycemia, improved glucose levels, weight loss, and increased time in range.

Discussion: Studies described show an improvement in diabetes-related clinical outcomes with CGM use in low-income patients. Difficulty identifying the setting of the studies was the main limitation of this review. Insights highlight the need for research on interventions to enhance CGM access and address barriers to promote health equity in underserved populations especially as CGM becomes available over-the-counter.

Other: No funding was issued for this research.
