Estimating the cost‐effectiveness of intermittently scanned continuous glucose monitoring in adults with type 1 diabetes in England

Diabet MedPublished Cost-effectiveness analysis of a randomised trial

Authors' conclusion

While isCGM is associated with increased short-term costs, compared with SMBG, its benefits in lowering HbA1c will lead to sufficient long-term health-gains and cost-savings to justify costs, so long as the effect lasts into the medium term.

Study context

Population
Adults with T1D and high HbA1c (58–97 mmol/mol [7.5%-11%]), England
Comparison
Intermittently scanned continuous glucose monitoring (isCGM) vs SMBG
Primary endpoint

Further findings

OutcomeEstimate
Within-trial QALY and cost · 24 weeksisCGM vs SMBG · non-significantadjusted incremental QALY gain 0.006 (95% CI −0.007 to 0.019)
Within-trial QALY and cost · 24 weeksisCGM vs SMBGadjusted cost increase per participant £548 (95% CI 381–714)

Subgroups · lifetime

In all subgroups, isCGM incremental cost-per-QALY better than £20,000 vs SMBG
Baseline HbA1c >75 mmol/mol (9.0%): isCGM cost-saving

Sensitivity analysis

isCGM remains cost-effective if its effectiveness lasts for at least 7 years
