The Cost-Effectiveness Analysis of an Integrated Mental Health Care Programme in Germany

The network for mental health (NWpG = Netzwerk psychische Gesundheit) is an umbrella association for non-medical community mental health care facilities across Germany which are enabled to provide multi-professional mental health care packages including medical and psychosocial services reimbursed by German statutory health insurances since 2009. The aim of this study is to analyse the cost-effectiveness of providing NWpG mental health care packages plus treatment as usual (NWpG) to treatment as usual alone (TAU) in Germany. In a prospective, multicenter, controlled trial over 18 months, a total of 511 patients (NWpG = 251; TAU = 260) were observed in five regions, four times at six-month intervals. The EQ-5D-3L and the Client Sociodemographic and Service Receipt Inventory (CSSRI) were used to estimate quality-adjusted life-years and total costs of illness. Propensity score-adjusted cost–utility analysis was applied using the net benefit approach. No significant differences in costs and QALYs between NWpG and TAU groups were identified. The probability of NWpG being cost-effective compared to TAU was estimated below 75% for maximum willingness to pay (MWTP) values between 0 and 125,000 EUR. The additional provision of the NWpG package is not cost-effective compared to TAU alone.

Does one size really fit all? The effectiveness of a non-diagnosis-specific integrated mental health care program in Germany in a prospective, parallel-group controlled multi-centre trial

BACKGROUND

The Network for Mental Health (NWpG-IC) is an integrated mental health care program implemented in 2009 by cooperation between health insurance companies and community mental health providers in Germany. Meanwhile about 10,000 patients have been enrolled. This is the first study evaluating the effectiveness of the program in comparison to standard mental health care in Germany.

METHODS

In a parallel-group controlled trial over 18 months conducted in five regions across Germany, a total of 260 patients enrolled in NWpG-IC and 251 patients in standard mental health care (TAU) were recruited between August 2013 and November 2014. The NWpG-IC patients had access to special services such as community-based multi-professional teams, case management, crisis intervention and family-oriented psychoeducation in addition to standard mental health care. The primary outcome empowerment (EPAS) and the secondary outcomes quality of life (WHO-QoL-BREF), satisfaction with psychiatric treatment (CSQ-8), psychosocial and clinical impairment (HoNOS) and information about mental health service needs (CAN) were measured four times at 6-month intervals. Linear mixed-effect regression models were used to estimate the main effects and interaction effects of treatment, time and primary diagnosis. Due to the non-randomised group assignment, propensity score adjustment was used to control the selection bias.

RESULTS

NWpG-IC and TAU groups did not differ with respect to most primary and secondary outcomes in our participating patients who showed a broad spectrum of psychiatric diagnoses and illness severities. However, a significant improvement in terms of patients' satisfaction with psychiatric care and their perception of treatment participation in favour of the NWpG-IC group was found.

CONCLUSIONS

Providing integrated mental health care for unspecific mentally ill target groups increases treatment participation and service satisfaction but seems not suitable to enhance the overall outcomes of mental health care in Germany. The implementation of strategies for ameliorating the needs orientation of the NWpG-IC should be considered.
