Primary outcomePrimary: Change in Glycated Hemoglobin- HbA1c — -0.14; -0.09 Change in A1c (%)
Summary
Our objective is to test the feasibility, acceptability, and initial efficacy of using behavioral economics incentives (BEI) in a novel, semi-automated intervention to target daily insulin BOLUS scores in adolescents with suboptimal insulin use.
