The administration of rapid-acting insulin per sliding scale (SSI) for correction of hyperglycemia in non-ICU patients with type 2 diabetes (T2D) is used with most basal-bolus insulin (BBI) regimens; however, the safety and efficacy of using SSI has not been tested in RCTs. In this non-inferiority RCT, we tested whether correction of hyperglycemia before meals and bedtime improves glycemic control in patients treated with BBI regimens.

Patients with T2D with a blood glucose (BG) > 140 mg/dl treated with BBI were randomized to SSI for BG >140 mg/dl (intensive supplement) or to SSI for BG >260 mg/dl (non-intensive supplement). Primary outcome was difference in mean BG levels between the groups during hospital stay. There were no differences in baseline characteristics between the intensive and non-intensive supplement groups. There were no differences between groups in mean daily BG, length of stay (LOS), hypoglycemia (BG < 70 or < 54 mg/dl), severe hyperglycemia (BG > 350 mg/dl), and total, basal, prandial or supplemental daily insulin doses (U/day). In patients with any BG 140-260 mg/dl and without BG > 260 mg/dl, mean BG did not differ but non-intensive group needed more prandial insulin.

Conclusion: Adding correction/supplement SSI in non-ICU T2D patients with mild to moderate hyperglycemia (<260 mg/dl) on basal bolus regimen does not improve glycemic control.
