Health economic evaluation of the Danish IBBIS randomized controlled trials

Health economic evaluation of the danish ibbis randomized controlled trials

The IBBIS interventions, which integrated healthcare with vocational rehabilitation, were not found to be cost-effective compared with usual services, with negative economic outcomes in both intervention arms.

Common mental disorders (CMD), including depression, anxiety, and stress-related disorders, affect approximately 20% of the adult population and have a substantial impact on labor force participation and productivity; the IBBIS trials aimed to evaluate the health economic impact of integrating healthcare with vocational rehabilitation for these individuals. Two parallel randomized controlled trials (RCTs) were conducted among adults who had been on sick leave for at least four weeks and had been diagnosed with anxiety, depression, or a stress-related disorder; participants were randomized to three groups: Service As Usual (SAU), IBBIS Mental Health Care (MHC), and the IBBIS Integrated Intervention (INT). Data were collected from Danish national registers (healthcare services, vocational rehabilitation, and social benefit transfers), and economic outcomes were analyzed over a 24-month follow-up from both societal and public budget perspectives. Both IBBIS interventions showed a negative economic impact compared with SAU: at 24 months, the per-participant impact from a societal perspective was −€4,645 for INT and −€7,680 for MHC; from a public budget perspective, it was −€2,994 for INT and −€5,831 for MHC. The main driver was reduced productivity, with no significant improvement in health-related quality of life to offset it. The interventions were not cost-effective; highlighting the economic challenges of current interventions for common mental disorders, the authors note that developing and testing new approaches that address both health and vocational outcomes remains an unresolved area of research.
