The Dutch mental healthcare sector underwent an important change in 2008. Most of mental healthcare services – both primary and secondary – were transferred to the basic health insurance scheme (ZVW). This reform triggered several effects such as increased overall expenditure, a greater number of (self-employed) providers, and innovation. The role of health insurers became much stronger in this sector. Budgets were replaced with an output-based payment system that implies negotiations between insurers and providers on price per service. Regulated competition was introduced in mental healthcare. This research area draws upon the effects of this policy change on public goals such as affordability, accessibility, and quality of mental health. We seek to examine a diverse range of issues and trends that impact this sector.
