This article reports key findings from recent randomized, observational, and retrospective studies investigating use of CGM in type 2 diabetes (T2D) individuals treated with basal insulin only and/or noninsulin therapies. Data from 29 studies were reviewed and analyzed. Both randomized and prospective/retrospective studies have demonstrated significant glycemic improvement, reductions in diabetes-related events and hospitalization rates, and cost benefits of persistent CGM use by individuals with T2D who are treated with basal insulin only, basal plus noninsulin medications, and noninsulin medications without insulin. In 23 (79%) of the 29 studies reviewed, investigators reported associations between CGM and improvements in HbA1c and/or key CGM metrics. These findings, alone, provide strong evidence that supports providing access to this technology to those with T2D who are less intensively treated. The narrative presents an evidence-based rationale for expanded access to CGM within the T2D basal insulin only and/or noninsulin treated population. Recent clinical guidelines from the American Diabetes Association and American Association of Clinical Endocrinology now endorse CGM use in individuals treated with nonintensive insulin regimens. Access in the basal insulin only population has expanded since the start of this project. CGM should be made readily available to all individuals with diabetes who are able to use this technology safely and effectively.
