Advanced Diabetes Management Using Artificial Intelligence and Continuous Glucose Monitoring Sensors

Open access

Abstract

Wearable continuous glucose monitoring (CGM) sensors are revolutionizing the treatment of type 1 diabetes (T1D). These sensors provide in real-time, every 1–5 min, the current blood glucose concentration and its rate-of-change, two key pieces of information for improving the determination of exogenous insulin administration and the prediction of forthcoming adverse events, such as hypo-/hyper-glycemia. The current research in diabetes technology is putting considerable effort into developing decision support systems for patient use, which automatically analyze the patient’s data collected by CGM sensors and other portable devices, as well as providing personalized recommendations about therapy adjustments to patients. Due to the large amount of data collected by patients with T1D and their variety, artificial intelligence (AI) techniques are increasingly being adopted in these decision support systems. In this paper, we review the state-of-the-art methodologies using AI and CGM sensors for decision support in advanced T1D management, including techniques for personalized insulin bolus calculation, adaptive tuning of bolus calculator parameters and glucose prediction.

TL;DR

This narrative review surveys state-of-the-art artificial intelligence (AI) methods that use continuous glucose monitoring (CGM) sensor data to support advanced type 1 diabetes (T1D) management. It focuses on three decision-support tasks: personalized insulin bolus calculation, adaptive tuning of bolus calculator parameters, and glucose prediction.

Key findings

  • For personalized bolus calculation, a neural-network-based bolus calculator that corrects the standard formula achieved significantly lower blood glucose risk index (BGRI) values than the standard formula in silico, though in a non-negligible number of cases it performed worse; a separate LASSO-regularized linear regression formula (14 features, trained on 100 virtual subjects across 162,000 subject–meal combinations) also produced lower BGRI than the standard formula.
  • For adaptive parameter tuning, a run-to-run plus case-based reasoning (R2R+CBR) algorithm improved glycemic control over stand-alone R2R in 20 virtual subjects and was robust to carb-counting error and CGM noise; implemented as ABC4D, it was tested in a six-week non-randomized study of 10 adults with T1D and reduced postprandial hypoglycemia. A temporal CBR variant reduced BGRI by up to 27% after three revisions in a six-month in silico study.
  • For glucose prediction, benchmarking on the OhioT1DM dataset at a 30-min prediction horizon found best RMSE of 19–20 mg/dL (ARX, Ridge, linear SVR, LSTM, TCN), with maximum time gain of about 7 min (gradient boosting trees, LSTM); linear SVR and TCN gave RMSE ~20 mg/dL with ~6 min time gain.
  • An XGBoost-based classifier for postprandial glycemic status, used to adjust meal boluses, improved time in euglycemia from 61.98% to 67.00% without increasing time in hypoglycemia in 100 virtual adults; a decision tree and random forest for exercise hypoglycemia reached 79.55% and 86.67% accuracy respectively.

Methods

  • Narrative (non-systematic) review of AI-based decision support systems for patient use in T1D, organized around three tasks: personalized insulin bolus calculation, adaptive tuning of bolus calculator parameters, and glucose prediction.
  • Describes specific algorithms and their validation studies, including in silico simulations using the UVa/Padova T1D Simulator, retrospective real-data analyses, and the OhioT1DM benchmarking dataset.
  • Performance metrics discussed include BGRI, RMSE, time gain (TG), time in euglycemia, and classification accuracy.

Limitations

  • The paper states that most reviewed techniques were validated only in silico or on retrospective real data, and that prospective clinical validation proving safety and effectiveness is required before adoption in T1D management.
  • The paper notes the NN-based bolus calculator led to worse glycemic control than the standard formula in a non-negligible number of cases, and that the standard formula's structure may intrinsically limit correction-based approaches.
  • The paper states the exercise-hypoglycemia prediction study (Reddy et al.) used data collected only in a controlled inpatient environment, requiring validation under free-living conditions and with different exercise types; it also notes the Patient Safety System modules were each validated only on retrospective data and need clinical validation.

Figures

Figure 1 A general structure of a DSS for patient use. By using information on glucose concentration, insulin administrations, meal intakes and physical activity, a DSS provides recommendations on optimal insulin dosage and several other useful features to help patient in managing diabetes. A DSS usually implements three modules: Personalized insulin bolus calculation (Section 3), adaptive tuning of bolus calculator parameters (Section 4) and glucose prediction (Section 5).

Figure 4 Representative example to illustrate the efficacy of a predictive hypoglycemia alert. (A) Imaginary CGM profile of a patient using standard threshold-crossing alerts. A hypo alert is generated at time 8:15 when CGM crosses the hypoglycemia threshold. Even if this patient takes some carbs in response to the alert, the patient spends some time in hypoglycemia. (B) Example of how a low predictive alert can help to avoid hypoglycemic events. In this example, the alert is generated at 7:55, when the 20-min ahead glucose prediction crosses the hypoglycemia threshold. If the patient takes carbs in response to the predictive alert, it will be possible to prevent the hypoglycemia.

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.

A language model drew the claims from the paper on 2026-10-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-09 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

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.
