Objective
Glargine and detemir insulin are the two most commonly prescribed basal insulin analogs for the ambulatory and inpatient management of diabetes. The efficacy and safety of basal insulin analogs in the hospital setting has not been established.
Methods
This observational study compared differences in glycemic control and outcomes in non-ICU patients with blood glucose (BG) >140 mg/dl who were treated with glargine or detemir, between 01/01/2012 and 09/30/2015 in two academic centers.
Results
Among 6,245 medical and surgical patients with hyperglycemia, 5,749 received ≥ 1 dose of glargine and 496 patients received detemir during the hospital stay. There were no differences in the mean daily BG (glargine 182±46 mg/dl and detemir 180±44 mg/dl, p=0.70). There were no differences in mortality, hospital complications, or readmissions between groups (all, p= NS). After adjusting for potential confounders, there was no statistically significant difference in hypoglycemia rates between treatment groups. Patients treated with detemir also required higher total daily basal insulin doses (0.27 ± 0.16 vs 0.22 ± 0.15 units/kg/day, p <0.001). Glargine-treated patients had statistically longer LOS, however this difference may not be clinically relevant [6.8 ± 7.4 vs 6.0 ± 6.3 days, p <0.001].
Conclusions
Our study indicates that treatment with glargine and detemir resulted in similar inpatient glycemic control in general medicine and surgery patients. Detemir treatment was associated with higher daily basal insulin dose and number of injections. A prospective randomized study is needed to confirm these findings.
