Addition of continuous glucose monitoring to glucagon-like peptide 1 receptor agonist treatment for type 2 diabetes mellitus – An economic evaluation
Bibliographic record
Abstract
BACKGROUND: Both glucagon-like peptide 1 receptor agonists (GLP-1 RAs) and continuous glucose monitoring (CGM) have been shown to improve glycated hemoglobin A1c (A1c) levels among patients with type 2 diabetes mellitus (T2DM). Recently, a US real-world study found statistically significant improvements in A1c levels among patients using GLP-1 RA and a CGM device, compared with a matched cohort receiving only GLP-1 RA. OBJECTIVES: To assess the cost-effectiveness from a US payer perspective of initiating CGM (FreeStyle Libre Systems) in people living with T2DM using a GLP-1 RA therapy, compared with GLP-1 RA alone. METHODS: A patient-level microsimulation model was run for 10,000 patients over a lifetime horizon with 3.0% discounting for costs and utilities. Patient characteristics were based on the overall population of the US real-world study and the subgroup of patients not using intensive insulin. The effect of CGM was modeled as a persistent reduction in A1c compared with GLP-1 RA alone (overall = 0.37%; patients not using intensive insulin = 0.34%). Costs ($2,023) and disutilities were applied to diabetes complications and acute diabetic events. Outcomes were assessed as quality-adjusted life years (QALYs). RESULTS: The base-case incremental cost-effectiveness ratio (incremental costs/incremental QALYs) for GLP-1 RA plus CGM vs GLP-1 RA alone was $40,968/QALY in the overall cohort (cost = $484,180 vs $473,938; QALYs = 13.37 vs 13.12). Among patients not using intensive insulin, the incremental cost-effectiveness ratio was $43,095/QALY. Scenario analysis showed that the model results were robust to changing assumptions. Probabilistic sensitivity analysis showed that GLP-1 RA plus CGM had a 64% probability of being cost-effective at a willingness-to-pay threshold of $100,000 per QALY. CONCLUSIONS: From a US payer perspective, CGM is cost-effective when added to GLP-1 RA therapies for the treatment of T2DM, including for patients not using intensive insulin.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
