Summary

This non-blinded, non-randomized pre-post study will examine the impact of providing CGM sensors free of charge to adult patients of Fair Haven Community Health Care with poorly controlled type 2 diabetes on glycemic control and quality of life.

Detailed description

This study will enroll adult patients with type 2 diabetes and A1c of 8.0 or greater despite long-term use of insulin who are underinsured and under-resourced , meaning they are unable to reasonably afford CGM sensors. The participants will be chosen from among the panels of three providers. This study aims to determine whether providing CGMs free of charge to patients with poorly controlled diabetes who could not otherwise afford them positively impacts their glycemic control and quality of life. FHCHC's clinicians will identify adult patients from their panel with type 2 diabetes and poor glycemic control (A1c at least 8) on insulin who may be unable to afford CGM. Once consented, participants will have point-of-care A1c testing as well as pregnancy testing (if applicable); patient eligibility based on glycemic control criterion should be determined by this A1c. Participants will then complete the study questionnaires. Clinic staff will teach CGM sensor placement and determine whether a reader is required or if a compatible mobile device for intermittent scanning will be used. Blood Glucose (BG) readings are provided via online Libre portal. At the 6-week follow-up visit, the provider will recommend adjustments to the participant's medication regimen based on their BG trends on CGM and their clinical judgment. Providers will ask participants to report any adverse events, safety issues, or trouble with the CGM system thus far experienced. At the 12-week follow-up visit, participants will repeat completion of study questionnaires and undergo second A1c measurement. Further adjustment to medication regimen is permitted as provider sees fit. At the 24-week follow-up visit, participants will repeat completion of study questionnaires for a third time and undergo third A1c measurement.

Conditions

• Diabetes
• Type 2 Diabetes
• Type 2 Diabetes Mellitus - Poor Control

Interventions

Type	Name	Description
DEVICE	Continuous Glucose Monitor (CGM)	The first CGM sensor will be applied as directed during the first visit with a brief training by staff. Participant will be instructed to remove and replace the device every 14 days for the remainder of the 3-month trial period. Participant will also be instructed to scan the sensor three times daily. Compliance may be tracked via remote accessing of the blood glucose log on the online FreeStyle portal. CGM models used will include the Abbott FreeStyle Libre 2 and 3 and Dexcom G5, G6 and G7.
