Impact of Initial eGlycemic Management System Dosing Strategy on Time to Target Blood Glucose Range

Area of Science:

• Endocrinology
• Medical Informatics

Background:

• Electronic glycemic management systems (GMS) are standard for glycemic control.
• GMS provides insulin dosing recommendations based on blood glucose (BG) trends.
• Initial dosing strategies (custom vs. weight-based multiplier) impact GMS effectiveness.

Purpose of the Study:

• Evaluate the impact of initial subcutaneous GMS insulin dosing strategies on glycemic management.
• Compare custom vs. weight-based multiplier settings for initial GMS insulin dosing.

Main Methods:

• Retrospective chart review of non-intensive care unit patients using subcutaneous GMS.
• Compared custom (provider discretion) vs. weight-based multiplier (0.3, 0.5, 0.7 units/kg/day) initial dosing.
• Primary endpoint: time to target BG; Secondary endpoints: BG in range, LOS, hypoglycemia/hyperglycemia rates.

Main Results:

• No significant difference in time to target BG between custom and multiplier groups (55 vs. 64 hours, P=.07).
• Less than half of patients achieved target BG in both groups (47% vs. 44%).
• No differences observed in LOS, BG in range, hypo/hyperglycemia rates, or average BG.

Conclusions:

• Custom initial subcutaneous GMS insulin dosing showed a nonsignificant decrease in time to target BG range compared to multiplier settings.
• Future studies should investigate the impact of compliance with institutional recommendations on BG control.
