Background and Aims:My Diabetes My Way (MDMW) is Scotland’s interactive website and mobile app
for people with diabetes and their caregivers. It contains multimedia
resources for diabetes education and offers access to electronic personal
health records. This study aims to assess the cost-utility of MDMW compared
with routine diabetes care in people with type 2 diabetes who do not use
insulin.Materials and Methods:Analysis used the United Kingdom Prospective Diabetes Study (UKPDS) Outcomes
Model 2. Clinical parameters of MDMW users (n = 2576) were compared with a
matched cohort of individuals receiving routine care alone (n = 11 628).
Matching criteria: age, diabetes duration, sex, and socioeconomic status.
Impact on life expectancy, quality-adjusted life years (QALYs), and costs of
treatment and complications were simulated over ten years, including a 10%
sensitivity analysis.Results:MDMW cohort: 1670 (64.8%) men; average age 64.3 years; duration of diabetes
5.5 years. 906 (35.2%) women: average age 61.6 years; duration 4.7 years.
The cumulative mean QALY (95% CI) gain: 0.054 (0.044-0.062) years. Mean
difference in cost: –£118.72 (–£150.16 to –£54.16) over ten years.
Increasing MDMW costs (10%): –£50.49 (–£82.24-£14.14). Decreasing MDMW costs
(10%): –£186.95 (–£218.53 to –£122.51).Conclusions:MDMW is “dominant” over usual care (cost-saving and life improving) in
supporting self-management in people with type 2 diabetes not treated with
insulin. Wider use may result in significant cost savings through delay or
reduction of long-term complications and improved QALYs in Scotland and
other countries. MDMW may be among the most cost-effective interventions
currently available to support diabetes.
