NPH and Regular Insulin in the Treatment of Inpatient Hyperglycemia: Comparison of 3 Basal-bolus Regimens

Patients will receive NPH insulin in a once-daily regimen. The starting dose is calculate according to body mass index (BMI): 0.3 U/kg for BMI \< 18 kg/m2, 0.4 U/kg for BMI 18-24.9 kg/m2, 0.5 U/kg for BMI 25-29.9 kg/m2 and 0.6 U/kg for BMI ≥ 30 kg/m2. The resulting dose will be fractioned to be given 60% as basal insulin (NPH) and 40% as prandial insulin (Regular). NPH insulin in the once-daily regimen will be administered subcutaneously before breakfast. Regular insulin subcutaneously wil be given in three equally divided doses before each meal.

Patients receive NPH insulin in twice-daily regimen. The starting dose is calculated according to body mass index (BMI): 0.3 U/kg for BMI \< 18 kg/m2, 0.4 U/kg for BMI 18-24.9 kg/m2, 0.5 U/kg for BMI 25-29.9 kg/m2 and 0.6 U/kg for BMI ≥ 30 kg/m2. The resulting dose will de fractioned to be given 60% as basal insulin (NPH) and 40% as prandial insulin (Regular). NPH insulin in the twice-daily regimen will be administered subcutaneously before breakfast and before dinner. Regular insulin will be given in three equally divided doses before each meal.

Patients receive NPH insulin in a triple-daily regimen. The starting dose was calculated according to body mass index (BMI): 0.3 U/kg for BMI \< 18 kg/m2, 0.4 U/kg for BMI 18-24.9 kg/m2, 0.5 U/kg for BMI 25-29.9 kg/m2 and 0.6 U/kg for BMI ≥ 30 kg/m2. The resulting dose will be fractioned to be given 60% as basal insulin (NPH) and 40% as prandial insulin (Regular). NPH insulin in the triple daily regimen will be administered subcutaneously before each meal. Regular insulin will be given in three equally divided doses before each meal.
