Abstract

Background: The MiniMed™ 780G system includes an advanced hybrid closed loop (AHCL) algorithm that provides both automated basal and correction bolus insulin delivery. The preliminary performance of the system in real-world settings was evaluated. Methods: Data uploaded from August 2020 to March 2021 by individuals living in Belgium, Finland, Italy, the Netherlands, Qatar, South Africa, Sweden, Switzerland, and the United Kingdom were aggregated and retrospectively analyzed to determine the mean glucose management indicator (GMI), percentage of time spent within (TIR), below (TBR), and above (TAR) glycemic ranges, system use, and insulin consumption in users having ≥10 days of sensor glucose (SG) data after initiating AHCL. The impact of initiating AHCL was evaluated in a subgroup of users also having ≥10 days of SG data, before AHCL initiation. Results: Users ( N = 4120) were observed for a mean of 54 ± 32 days. During this time, they spent a mean of 94.1% ± 11.4% of the time in AHCL and achieved a mean GMI of 6.8% ± 0.3%, TIR of 76.2% ± 9.1%, TBR <70 of 2.5% ± 2.1%, and TAR >180 of 21.3% ± 9.4%, after initiating AHCL. There were 77.3% and 79.0% of users who achieved a TIR >70% and a GMI of <7.0%, respectively. Users for whom comparison with pre-AHCL was possible ( N = 812) reduced their GMI by 0.4% ± 0.4% ( P = 0.005) and increased their TIR by 12.1% ± 10.5% ( P < 0.0001), post-AHCL initiation. More users achieved the glycemic treatment goals of GMI <7.0% (37.6% vs. 75.2%, P < 0.0001) and TIR >70% (34.6% vs. 74.9%, P < 0.0001) when compared with pre-AHCL initiation. Conclusion: Most MiniMed 780G system users achieved TIR >70% and GMI <7%, while minimizing hypoglycemia, in a real-world condition.

  • Both generation 1 low-glucose-suspend and generation 2 hybrid closed-loop systems improve glycated haemoglobin concentrations, time in target range, and time below target range in children, adolescents, and adults.

    “Both generation 1 low-glucose-suspend33 and generation 2 hybrid closed-loop systems improve glycated haemoglobin concentrations, the time in target range and the time below target range in children, adolescents34 and adults.35-37”

    The Results (‘Impact of initiating AHCL’; page unavailable) report that, among 812 users, MiniMed 780G initiation lowered GMI and time below range and increased time in range. This supports the hybrid closed-loop portion of the claim, but GMI is an estimate rather than a measured glycated haemoglobin concentration. The paper also does not report these changes specifically for adults; the low-glucose-suspend portion carries a different citation. (LLM, conf=0.86)

  • Advanced hybrid closed-loop systems continuously adjust basal insulin delivery every five minutes based on real-time continuous glucose monitoring data and automatically administer correction boluses in response to hyperglycemia, facilitating maintenance of glucose levels near predefined targets.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
