Continuous Glucose Monitoring Following Hospital Discharge

Effect of Continuous Glucose Monitoring Following Hospital Discharge of Patients With Type 2 Diabetes

In this 12-week prospective observational cohort study, hospitalized insulin-requiring patients with T2D will receive a Dexcom continuous glucose monitor (CGM) to wear post-hospital discharge. Patients will complete surveys assessing patient-reported outcomes prior to CGM use and following completion of the study. CGM data will be captured by the patient smartphone app and analyzed. Patients will receive personalized CGM targets and alerts for hyperglycemia and hypoglycemia. Customized reports/ decision support will be sent to the usual diabetes provider. The initial observational cohort study design will be followed by an extension phase of 12 weeks in which data on continuation of use and glucose control will be collected but no further reports will be communicated to providers.

The Diabetes Treatment Satisfaction Questionnaire (change) will be administered at enrollment and at 12 weeks. Total scores will be compared. The DTSQc compares the experience of the current treatment with the experience of the treatment before initiation of the study. Scores range from +3 ("much more satisfied now") to -3 ("much less satisfied now"), with 0 (midpoint) representing no change. Higher scores on the DTSQ total score indicate higher treatment satisfaction, and lower scores indicate lower treatment satisfaction.
