Abstract
AIM
The Counterweight-Plus weight management programme achieved 46% remission of Type 2 diabetes at 1 year in the DiRECT trial. We estimated the implementation costs of the Counterweight-Plus programme and its 1-year cost-effectiveness in terms of diabetes remission, compared with usual care, from the UK National Health Service (NHS) perspective.
METHODS
Within-trial total costs included programme set-up and running costs (practitioner appointment visits, low-energy formula diet sachets and training), oral anti-diabetes and anti-hypertensive medications, and healthcare contacts. Total costs were calculated for aggregated resource use for each participant and 95% confidence intervals (CI) were based on 1000 non-parametric bootstrap iterations.
RESULTS
One-year programme costs under trial conditions were estimated at £1137 per participant (95% CI £1071, £1205). The intervention led to a significant cost-saving of £120 (95% CI £78, £163) for the oral anti-diabetes drugs and £14 (95% CI £7.9, £22) for anti-hypertensive medications compared with the control. Deducting the cost-savings of all healthcare contacts from the intervention cost resulted an incremental cost of £982 (95% CI £732, £1258). Cost per 1 year of diabetes remission was £2359 (95% CI £1668, £3250).
CONCLUSIONS
Remission of Type 2 diabetes within 1-year can be achieved at a cost below the annual cost of diabetes (including complications). Providing a reasonable proportion of remissions can be maintained over time, with multiple medical gains expected, as well as immediate social benefits, there is a case for shifting resources within diabetes care budgets to offer support for people with Type 2 diabetes to attempt remission.
