New and Stress hyperglycemia • Patients with hyperglycemia without a previous history of diabetes should be tested with a hemoglobin A1C during the hospital stay or with an oral glucose tolerance test after discharge to confirm the diagnosis of diabetes. • Less than 35% of patients had normal glucose tolerance after 3 to 12 months of follow-up.

A1C for Diagnosis of Diabetes in the Hospital • Inhospital hyperglycemia is defined as an admission or inhospital BG > greater 140 mg/dl. • HbA1c > 6.5% can be identified as having diabetes, and patients with A1C 5.7%-6.4% can be considered as being at risk for diabetes. • Implementation of A1C testing can be useful: • assess glycemic control prior to admission • assist with differentiation of newly diagnosed diabetes from stress hyperglycemia • designing an optimal regimen at the time of discharge

RABBIT 2 SURGERY Summary & Conclusion Treatment with glargine once daily plus glulisine before meals improved glycemic control and reduced hospital complications compared to SSRI in general surgery patients with T2DM. Our study indicates that basal/bolus insulin regimen is the preferred insulin regimen in the hospital management of general surgery patients with type 2 diabetes.
Management Recommendations • All patients with T1DM must receive insulin treatment with basal bolus, multi-dose insulin combination of NPH plus regular insulin or continuous insulin pump. • Patients treated with insulin at home should be continued with insulin therapy in the hospital. • Scheduled subcutaneous basal bolus insulin regimen is preferred for the majority of non-critically ill patients with hyperglycemia. • The practice of using sliding scale insulin (SSI) as a single form of therapy is undesirable.
Strategies for Preventing Hypoglycemia • In-service training on new treatment modalities and the actions of new antihyperglycemic agents • Reducing outpatient insulin dose in patients treated with insulin prior to admission • Basal Bolus is preferred over SSRI and NPH/regular combination Braithwaite SS, et al. Endocr Pract. 2004;10(suppl 2):89-99.
Basal Bolus Insulin Regimen in T2DM: Summary • D/C oral antidiabetic drugs on admission • Starting total daily dose (TDD): • 0.3 U/kg/d in elderly and renal failure (lean?) • 0.4 U/kg/d x BG between 140-200 mg/dL • 0.5 U/kg/d x BG between 201-400 mg/dL • Half of TDD as insulin glargine and half as rapid-acting insulin (lispro, aspart, glulisine) • Decrease outpatient insulin dose by 20-25% Umpierrez et al, Diabetes Care 2007; JCEM 2009; Diabetes 2010
