About this study

In plain language

This study looks at whether continuous glucose monitors help people understand blood sugar tracking and feel more satisfied with their diabetes care after leaving the hospital. It is for adults at VUMC who need insulin during their hospital stay and when they go home.

This study aims to improve patient awareness of the utility of continuous glucose monitoring systems in blood glucose monitoring and to improve patient satisfaction regarding diabetes care, particularly in the matter of blood glucose monitoring, at the transitions of care from the inpatient setting to the ambulatory setting.

Compensation is read from the study's own description and may be missing — always confirm with the study team.

Eligibility

Who can join

  • Age 18 or older, not pregnant, and admitted to VUMC.
  • Able to understand the study and agree to take part.
  • Have high blood sugar that needs insulin shots or your own insulin pump during your hospital stay and at discharge.
  • Have blood sugar readings of 70–350 mg/dL in the 24 hours before joining.
  • Need to check blood sugar at least once a day.
  • Able to understand and handle a Libre 3 Plus or Dexcom G7 sensor and use its app on your smartphone.

Who can't join

  • Using a Libre 3 Plus or Dexcom G7 glucose monitor in the hospital, or used one in the past 3 months; or do not have a smartphone that works with its app.
  • Received chemotherapy during this hospital stay, or plan to have major surgery within 10–15 days.
  • Receive dialysis, a treatment that removes waste when the kidneys cannot.
  • Need medicines to support blood pressure, a breathing tube, medicine to keep you sedated, or intensive care.
  • Take more than 500 milligrams of vitamin C a day, or take hydroxyurea.
  • Take acetaminophen at more than 4 grams a day or 1 gram every 6 hours.
  • Have severe swelling that leaves a dent when pressed (grade 3+ or higher), or signs of poor blood flow.
  • Arrive with diabetic ketoacidosis or a hyperosmolar nonketotic state—serious blood sugar emergencies—or have a skin allergy to adhesives used to stick sensors on.

Simplified for readability. The official criteria below are what the study team uses.
