Background : People with diabetes have a high risk of developing micro-and macrovascular complications associated with diminished life expectancy and elevated treatment costs. Patient education programs can improve diabetes control in the short term, but their cost-effectiveness is uncertain. Our study aimed to analyze the lifelong cost-effectiveness of a nurse-led tele-coaching program compared to usual care in people with type 2 diabetes from the perspective of the Belgian healthcare system.
Methods : The UKPDS Outcomes Model was populated with patient-level data from an 18-month randomized clinical trial in the Belgian primary care sector involving 574 participants; trial data were extrapolated to 40 years; Quality Adjusted Life Years (QALYs), treatment costs and Incremental Cost-Effectiveness Ratio (ICER) were calculated for the entire cohort and the subgroup with poor glycemic control at baseline ("elevated HbA1c subgroup") and the associated uncertainty was explored.
Results : The cumulative mean QALY (95% CI) gain was 0.21 (0.13; 0.28) overall and 0.56 (0.43; 0.68) in elevated HbA1c subgroup; the respective incremental costs were (sic)1,147 (188; 2,107) and (sic)2,565 (654; 4,474) and the respective ICERs (sic)5,569 ((sic)677; (sic)15,679) and (sic)4,615 (1,207; 9,969) per QALY. In the scenario analysis, repeating the intervention for lifetime had the greatest impact on the cost-effectiveness and resulted in the mean ICERs of (sic) 13,034 in the entire cohort and (sic)7,858 in the elevated HbA1c subgroup.
Conclusion : Taking into account reimbursement thresholds applied in West-European countries, nurseled telecoaching of people with type 2 diabetes may be considered highly cost-effective within the Belgian healthcare system
