• Background and aims : The development and application of digital technologies to healthcare is a key component in meeting the increasing demand from patients for chronic disease management. Healthcare payers need evidence to support value-based decisions on new technologies. Smart insulin pens record the timing and dose of insulin, and data can integrate with continuous glucose monitoring (CGM) to improve diabetes self-management. The present analysis assessed the cost-effectiveness of introducing a smart insulin pen from a Swedish public healthcare payer perspective. Materials andmethods : The IQVIA CORE DiabetesModel was used to project clinical outcomes and healthcare costs (2018 Swedish krona [SEK]) over patients’ lifetimes in a Swedish type 1 diabetes (T1D) population. The model projected the development of complications, mortality, HbA1c, hypoglycaemia and insulin dosing to estimate cost effectiveness. Clinical model inputs were informed by an observational study of the introduction of an NFC-enabled smart insulin pen (NovoPen® 6) in 94 adults with T1D receiving basal-bolus insulin and using CGM. Smar tinsulin pen use (median follow up 7 months) was associated with an additional 1.89 h/day time in range (TIR 3.9-10.0 mmol/L [70-180 mg/dL]) compared with baseline. Change in TIR was converted to change in HbA1c using a published regression equation to allow long-term outcomes to be modelled based on published risk equations. Additional TIR with the smart insulin pen translated to a 0.62% (6.8 mmol/mol) HbA1c reduction and there were 33 fewer CGM-documented non-severe hypoglycaemic events/patient/year (≥15 min <3.0 mmol/L [54 mg/dL]) relative to baseline. Baseline characteristics were taken from the study cohort or, if unavailable, adults with T1D from the Swedish National Diabetes Register. Future costs and clinical benefits were discounted at 3% annually. Costs were converted to Euros (EUR) using a 0.091 SEK exchange rate. Results : Over patients’ lifetimes, smart insulin pen use was associated with improved mean discounted quality-adjusted life expectancy (1.13 quality-adjusted life years) and cost savings (EUR11,091) vs standard care. Improvements in quality-adjusted life expectancy were driven by a lower frequency and delayed onset of complications predicted with the smart insulin pen relative to standard care. Higher treatment costs (due to the higher bolus insulin dose) with the smart insulin pen were offset by the lower cost of complications compared with standard care (Fig). Conclusion : In this long-term modelling analysis, lifelong use of a smart insulin pen improved clinical outcomes at a lower cost relative to standard care in a T1D population, suggesting that the smart insulin pen represents an efficient use of Swedish public healthcare resources in this patient population.
