Official title
A Randomized Controlled Trial Comparing Dexcom Continuous Glucose Monitoring to Point of Care Glucose Testing for the Management of Hospital and Post-Discharge Subjects With Type 1 Diabetes
About this study
The CDC reports that 1.6 million U.S. adults (5.7%) have type 1 diabetes (T1D), with hospitalization rates three times higher than the general population, primarily due to diabetes-related complications such as ketoacidosis and cardiovascular disease. A study at Emory University found that hospitalized T1D patients are younger, experience longer stays and more admissions, and face worse glycemic control and higher rates of hypoglycemia compared to type 2 diabetes (T2D) patients.
Point-of-care (POC) capillary glucose testing is the standard for monitoring hospitalized diabetes patients, but continuous glucose monitoring (CGM) offers more detailed glycemic profiles. Research, including trials using Dexcom CGM systems, has demonstrated CGM's superior ability to detect hypo- and hyperglycemia, reduce hypoglycemic events, and improve insulin therapy adjustments in T2D patients. However, no randomized controlled studies have evaluated the best glucose monitoring system for hospitalized T1D patients.
The proposed study aims to compare POC testing with Dexcom G7 CGM for guiding insulin therapy in hospitalized T1D patients. Researchers hypothesize that CGM will better prevent hypoglycemia and improve glycemic management during hospital stays, addressing a critical gap in evidence regarding glucose control's impact on T1D hospital outcomes.
Eligibility criteria
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
