Cost‐effectiveness analysis of a digital diabetes‐prevention programme versus an in‐person diabetes‐prevention programme in people with prediabetes in the United States
Authors' conclusion
The d-DPP is a cost-effective alternative to in-person lifestyle interventions for preventing the development of T2D among individuals with prediabetes in the United States.
Study context
- Population
- Simulated individuals with prediabetes in the United States, starting at age 45 years
- Exposure
- Digital diabetes prevention programme (DPP) vs in-person DPP
- Outcome
- Cost-effectiveness (costs and quality-adjusted life years (QALYs)) of d-DPP vs DPP for preventing T2D
- Follow-up
- 10-year period
Methodological detailsMarkov cohort model, societal and healthcare sector perspectives, 10-year time horizon, microsimulation of T2D complications, willingness-to-pay threshold $100 000 per QALY
- Markov cohort model
- Societal and healthcare sector perspectives
- 10-year time horizon
- Microsimulation of T2D complications
- Willingness-to-pay threshold $100 000 per QALY
