Clinician-Reported Barriers and Needs for Implementation of Continuous Glucose Monitoring

Continuous glucose monitoring (CGM) for patients with type 1 and type 2 diabetes is associated with improved clinical, behavioral, and psychosocial patient health outcomes and is part of the American Diabetes Association's Standards of Medical Care. CGM prescription often takes place in endocrinology practices, yet 50% of adults with type 1 diabetes and 90% of all people with type 2 diabetes receive their diabetes care in primary care settings. This study examined primary care clinicians' perceptions of barriers and resources needed to support CGM use in primary care.

This qualitative study used semistructured interviews with primary care clinicians to understand barriers to CGM and resources needed to prescribe. Participants were recruited through practice-based research networks. Rapid qualitative analysis was used to summarize themes from interview findings.

We conducted interviews with 55 primary care clinicians across 21 states. Participants described CGM benefits for patients with varying levels of diabetes self-management and engagement. Major barriers to prescribing included lack of insurance coverage for CGM costs to patients, and time constraints. Participants identified resources needed to foster CGM prescribing, for example, clinician education, support staff, and EHR compatibility.

Primary care clinicians face several challenges to prescribing CGM, but they are interested in learning more to help them offer it to their patients. This study reinforces the ongoing need for improved clinician education on CGM technology and continued expansion of insurance coverage for people with both type 1 and type 2 diabetes.
