PSUN227 A retrospective comparison of Basal Bolus using Glargine U-300 and Glulisine with Premix Insulin

OBJECTIVES: The objective of this retrospective analysis was to compare the occurrence of Level 1 hypoglycaemia, Level 2 hypoglycaemia, nocturnal hypoglycaemia and mean HBA1C reduction in patients treated with premixed insulin 30/70 (Insulin Isophane/NPH 70% + Human Insulin/Soluble Insulin 30%) and after initiating a basal bolus regime using Glargine U-300 and Glulisine. Level 1 hypoglycaemia is blood glucose less than 70 mg/dL but above 54 mg/dL. Level 2 hypoglycaemia is blood glucose less than 54 mg/dL. METHODOLOGY AND DATA ANALYSIS: Data was collected retrospectively over 6 months on adult outpatients who were on pre mix insulin 30/70 for at least 2 years and who frequently experienced hypoglycaemic episodes and after transitioning these patients to a basal bolus regime Glargine U-300 and Glulisine. Those were having an underlying etiology which would predispose them to hypoglycaemia were excluded. The exclusion criteria included malignancy, drug induced causes except premix insulin, Chronic Kidney disease stage 4 or 5 and acute or chronic hepatic failure. Blood glucose monitoring was done by a 7 point Self Monitoring of Blood Glucose. A total of 30 cases were randomly chosen and data were sought from patients’ home glucose logs, case notes and Electronic health care records. Data were analysed by Microsoft Excel and was compared with paired-T test. RESULTS: The average number of Level 1 hypoglycaemic episodes per week on premix insulin dropped from 6.517 to 0.9655 (t = -10.807456, p<0.00001) after initiating the basal bolus regime. The average number of level 2 hypoglycaemic episodes per week dropped from 2.034 to 0.379 (t = -8.733497, p<0.00001) after changing to basal bolus regime. There was also a reduction in the occurrence of average nocturnal hypoglycaemic episodes from 2.655 on pre mix insulin to 0.2068 on the basal bolus regimen (t = -8.635475, p<0.00001).The mean HbA1C reduction was 3.16% in three months after commencing the basal bolus regime (t = -27.554737, p<0.00001). CONCLUSIONS: Outpatient treatment with the basal bolus regime consisting of Glargine U -300 and Glulisine as compared to the premix insulin use showed a marked reduction in Level 1 and Level 2 hypoglycaemic episodes and nocturnal hypoglycaemic episodes per week. The decreased hypoglycaemic event rates in hypoglycaemia resulted in better compliance and adherence which was reflected as a significant reduction in HbA1C. In the future more retrospective and prospective studies will be helpful with Glargine U-300 and Glulisine. Presentation: Sunday, June 12, 2022 12:30 p.m. - 2:30 p.m.
