*Baxter et al. 2016 demonstrated cost reductions between £66 and £184 over 5 years from avoided complications if HbA1c was reduced by 0.4% from baseline. Based on this, we assume a median cost-reduction of £125 over 5 years that translates into cost-reduction of £25 per year due to avoided complications. If HbA1c reduction were equal to 1% from baseline (as seen in DIAMOND RCT for CGM), this equates to £63 in cost-reductions every year due to avoided complications. fBack calculated — Costing statement: type 1 diabetes in adults. CGM = continuous glucose monitoring; HbA1c = glycated haemoglobin; RCT = randomised controlled trial.
