SAFETY AND EFFICACY OF GLUCOSTABILIZER IN THE MANAGEMENT OF DIABETIC KETOACIDOSIS

To evaluate the safety and efficacy of GlucoStabilizer software intravenous insulin (IV) dosing in comparison to American Diabetes Association protocol-directed provider-guided insulin dose adjustment (PGIA). GlucoStabilizer calculates the dose of IV insulin required to reach a prescribed target glucose range. GlucoStabilizer has not been fully studied in DKA. This retrospective study compared outcomes in patients with DKA before and after the implementation of GlucoStabilizer. Insulin doses were administered based on GlucoStabilizer calculations or PGIA. The analysis evaluated before-after changes in the amount of insulin used, time to target, hypoglycemia or hypokalemia events, and the time to DKA resolution. We studied 77 patients with insulin doses calculated by GlucoStabilizer and 69 patients with PGIA dosing. GlucoStabilizer was superior to PGIA. Patients treated with GlucoStabilizer-calculated doses did not experience hypoglycemia (N = 0 versus N = 10; P<.001). The 10 unique PGIA patients had a total of 18 episodes with 17 between 55 to 69 mg/dL; 1 <54 mg/dL, and no episodes <40 mg/dL. The GlucoStabilizer group required less insulin to reach DKA resolution (59.2 versus 101.2 units; P<.001). Time to glycemic target and DKA resolution were similar (6.7 versus 4.6 hours; P = .132) and (9.8 versus 9.9 hours; P = .803), respectively. No difference in the incidence of hypokalemia was seen (N = 9 versus N = 11; P = .48). This study demonstrates the Gluco Stabilizer settings that can be successfully used in the management of DKA with the avoidance of hypoglycemia. Patients treated with GlucoStabilizer-calculated doses experienced no hypoglycemia and required less insulin as compared to those managed with PGIA.
