Abstract

Objectives: Depression is associated with high healthcare utilization and related costs. Effective treatments might reduce the economic burden. The objective of this study was to establish the cost-utility of a minimal psychological intervention (MPI) aimed at reducing depression and improving quality of life in elderly persons with diabetes or chronic obstructive pulmonary disease and co-occurring minor, mild, or moderate depression.Methods: Trial-based cost-utility analysis was used to compare the MPI with usual care. Annual costs and quality-adjusted life-years (QALYs) based on the Euroqol (EQ5D) and on depression-free days were calculated.Results: Annual costs and effects were not significantly different for the MPI group and care as usual. Bootstrap analysis indicated a dominant intervention, with a probability of 63 percent that the MPI is less costly and more effective than usual care.Conclusions: The cost-effectiveness analysis does not support dissemination of the MPI in its current form. The economic evaluation study showed limited probability that MPI is cost-effective over usual care. Further adjustments to the MPI are needed to make the intervention suitable for dissemination in regular care. Trial registration: isrctn.org, identifier: ISRCTN92331982
