NCT04089202

Brief Summary

Flash glucose monitoring is an FDA-approved and widely clinically available, glucose monitoring technology that is worn on the body and measures glucose values every 15 minutes, storing this data for up to 14 days. The Freestyle Libre Pro is already used as a diagnostic technology in clinical care. It provides a full 24-hour glucose profile for each day that the sensor is worn and that can be correlated with daily activities, medication administration, food intake, and other factors that are contextually relevant in meeting glycemic goals for an individual patient. In this study, patients referred to Endocrinology for specialty diabetes care will be randomized to an in-person visit as is typically done or to wear the Freestyle Libre Pro placed by staff at their primary care clinic. Patients who wear the Freestyle Libre Pro will have a professional interpretation of their glucose data completed by an endocrinologist as well as a remote eConsult completed using this glucose data and information from their medical record. The recommendations from the eConsult regarding medication and lifestyle adjustment as well as potential referral on to see Endocrinology will be implemented by the primary care physician at their clinical discretion. The investigators will utilize glycemic measures including hemoglobin A1c, number of clinical visits (outpatient, inpatient and emergency department) for diabetes care, patient reported outcomes including self-efficacy, and patient and provider assessments of burden to determine if eConsults utilizing flash glucose monitoring technology are non-inferior to in-person visits with a diabetes specialist.

    A1c will be obtained as standard of care and values documented in the medical record.

    baseline

  • Hemoglobin A1c (A1c) at 3 months

    A1c will be obtained as standard of care and values documented in the medical record.

    3 months

  • Hemoglobin A1c (A1c) at 6 months

    A1c will be obtained as standard of care and values documented in the medical record.

    6 months

Study Arms (2)

In-person visit arm

ACTIVE COMPARATOR

In this arm, patients meeting eligibility criteria and consented into the study are randomized to an in-person visit with an Endocrinologist. This is currently the standard of care for patients referred for diabetes specialty care. Care by the Endocrinologist is provided as would typically be done, taking into account patient factors and preferences. Surveys will be administered to measure patient burden and self efficacy.

Other: Standard of care

Freestyle Libre sensor arm

EXPERIMENTAL

In this arm, patients meeting eligibility criteria and consented into the study are randomized to have the Freestyle Libre Pro continuous glucose monitor (CGM) placed at their primary care clinic. The data collected from the diagnostic CGM will be utilized in conjunction with diet, exercise and medication logs provided by the patient and information from the patient's electronic medical record to complete an eConsult with treatment recommendations. Implementation of these recommendations will be per the primary care provider's discretion in conjunction with conversation with the patient in follow up visits. Surveys will be administered to measure patient burden and self efficacy.

Other: eConsult

Interventions

Completion of electronic consult utilizing data collected from flash glucose monitoring
