The MiniMed™ 780G system’s algorithm provides the possibility of lowering the burden of meal bolusing. The real-world data of over 61,000 system users demonstrate that bolusing 5-6 times/day, using recommended settings (target=100 mg/dL; active insulin time=2 hours) and 2-3 carbohydrate ratios (CRs) provides the highest time-in-range (81.3%). The current study determined that, with the aforementioned usage, optimal CRs/day for those aged ≤15 years and >15 years was 2- <3 CRs and 1- <2 CRs, respectively.
