N2 - Hyperglycemia during hospitalization is associated with increased rates of complications and longer hospital stays. Various insulin regimens are used in the inpatient diabetes management of non-critically ill patients. In this systematic review and meta-analysis, we aimed to assess the efficacy and safety of basal-bolus insulin therapy (BBI) by summarizing evidence from studies of BBI versus sliding scale insulin therapy (SSI) in the management of hospitalized non-critically ill type 2 diabetes patients. We searched MEDLINE, EMBASE, Scopus, and the Cochrane Library for studies comparing BBI therapy with SSI therapy in hospitalized non-critically ill patients with type 2 diabetes. Primary outcome was mean daily blood glucose (BG) during admission. Secondary outcomes were incidence of hypoglycemia and length of hospital stay. Results of included randomized controlled trials (RCT) were pooled and meta-analysed to provide estimates of the efficacy of BBI therapy. Five RCTs and seven observational studies were included in the review. Meta-analysis of RCTs showed significantly lower mean daily BG with BBI than SSI. Mean difference in daily BG between the two regimens ranged from 14 to 29 mg/dl. BBI therapy was associated with increased risk of mild hypoglycemia (BG ≤ 70 mg/dl, RR 5.75; 95% CI 2.79-11.83), (BG ≤ 60 mg/dl, RR 4.21; 95% CI 1.61-11.02) compared with SSI therapy. There was no difference in risk of severe hypoglycemia (BG ≤ 40 mg/dl) and no difference in mean length of stay. In conclusion, basal-bolus insulin in the inpatient diabetes management results in significantly lower mean daily BG than sliding scale insulin but is associated with increased risk of mild hypoglycemia.
