Oral Anti Diabetic Agents in the Hospital
Use of Oral Antidiabetic Agents in Hospitalized Patients With Diabetes
Study Overview
Status
Conditions
Detailed Description
Hyperglycemia in the hospital is common and has been associated with increased hospital complications, length of stay, and mortality. Improving glycemic control has been shown to improve length of stay, multi-organ failure, systemic infections, as well as short- and long-term mortality. Clinical guidelines from professional organizations recommend the use of subcutaneous (SQ) insulin as the preferred therapy for glycemic control in general medical and surgical patients with T2D. This approach, however, is labor intensive requiring multiple daily insulin injections, costly, and associated with significant risk of iatrogenic hypoglycemia
Over 75% of patients with T2D are treated with oral antidiabetic drugs (OADs) but due to the lack of safety and efficacy data from randomized controlled trials, clinical guidelines recommend stopping OADs during hospitalization. The current clinical guidelines have raised concerns with the use of OADs including risk of hypoglycemia with sulfonylureas, fluid retention and worsening of heart failure with thiazolidinediones, and risk of metformin-associated lactic acidosis in patients with severe renal impairment. However, several observational studies have reported that the use of OADs results in similar glycemic control without increased risk of complications compared to insulin regimens. A recent observational study that included 17,325 hospitalized patients with T2D, found that patients treated with OADs had similar glycemic control without differences in complications and no increase in rates of hypoglycemia compared to those treated with insulin.
This study will assess whether continuation of home oral antidiabetic agents during hospitalization can be used as a safe and effective alternative to insulin therapy in the management of diabetes in hospital patients with T2D. For a subset of participants (50 patients per group), a CGM devise will be placed for the duration of the study to assess parameters of glycemic control and hypoglycemia.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Oral Anti-diabetes Drugs (OADs) alone
OADs will be continued at same outpatient dosage unless contraindicated
|
OADs will be continued at same outpatient dosage unless contraindicated.
Participants will be switched to the preferred drug within the category of medication they take at home.
Dose adjustment for OADs will be based on clinical/laboratory status.
The OAD will be held if the participant is placed on strict nil per os (NPO) and is unable to take oral medications after enrollment.
Other Names:
Supplemental (correction) lispro or aspart insulin following the supplemental/sliding scale standard of care protocol for BG >140 mg/dl.
Other Names:
A subset of participants (50 per study arm) will be randomized to take part in an optional study where a CGM device will be placed for the duration of the study. CGM reports will be reviewed at the end of the study to assess parameters of glycemic control and hypoglycemia, and not used for insulin dose adjustment. The Dexcom CGM is a small sensor that inserts just under the skin to continuously monitor glucose levels. Results are transmitted to the wearer's smartphone every five minutes.
Other Names:
|
Active Comparator: Basal bolus insulin
Basal insulin with glargine or detemir and rapid-acting insulin (lispro/aspart) will be used as per the hospital formulary.
OADs and non-insulin injectable antidiabetic medication will be discontinued on admission.
