Can a wearable sensor beat fingersticks for hospital diabetes care?
NCT ID NCT06752928
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether using a Dexcom G7 continuous glucose monitor (CGM) instead of standard fingerstick blood sugar checks leads to better blood sugar control and fewer dangerous lows in hospitalized adults with type 1 diabetes. One hundred participants will be randomly assigned to either the CGM or fingerstick group during their hospital stay and after discharge. The goal is to see if the CGM helps keep blood sugar in a safer range.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Dexcom G7 continuous glucose monitor (device)
- What this could lead to
- If successful, this could show that continuous glucose monitoring improves blood sugar control and reduces dangerous lows during hospital stays for people with type 1 diabetes.
- What could go wrong
- This is a small, early-stage study (100 participants) comparing a device to standard care, so results may not apply broadly. The device itself has known accuracy limitations and skin irritation risks.

Inclusion Criteria: * Known history of T1D treated with insulin therapy (human regular or rapid-acting analogs or ultra-rapid analogs \[lispro, aspart, glulisine, fast-acting insulin aspart, insulin lispro\]), intermediate-acting (NPH and premixed formulations) or long-acting basal (glargine, detemir, degludec) formulations. * Admission diagnosis of T1D with poorly controlled diabetes (blood glucose \> 180 mg/dl, HbA1c \> 7%), including diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar state (HHS). * Expected length of hospital stay \> three days at the time of randomization Exclusion Criteria: * Patients admitted to the ICU * Subjects using CGM technology before admission * Subjects with type 2 diabetes * Treatment with systemic immunosuppressive agents * Cystic fibrosis * Prisoners * Patients expected to require MRI procedures during hospitalization. * Female subjects who are pregnant or breastfeeding at enrollment into the study. * Subjects not willing to wear a CGM device * Subjects with clinically relevant hepatic disease (diagnosed liver cirrhosis and portal hypertension) and end-stage kidney disease (eGFR\< 30 ml/min), or terminal illness. * Subjects with a history of cognitive impairment, dementia, or mental condition rendering the subject unable to understand the nature and consequences of the study
