[Voluntary and mandatory quality assurance in mental health care: European examples].

Since the turn of the century, quality assurance (QA) programs are increasingly being implemented; both generally in health systems and specifically for mental health services. These QA programs can be implemented on a mandatory basis as well as voluntarily. Benefits of mandatory QA programs are a reliable, country-wide dataflow, as well as their long-term sustainability and comparability. Shortcomings relate to the limitations imposed by legal requirements. Benefits of voluntary QA programs are their freedom and flexibility in terms of methods and data sources. Shortcomings relate to the impossibility of country-wide implementation and a lack of sustainability, as well as to the data quality. Examples for QA in mental health care from different European countries show that mandatory and voluntary QA initiatives could complement each other. Specialist medical societies play an important role in the development of voluntary QA and the promotion of high quality care. An example is the accreditation to mental health services offered by the Royal College of Psychiatrists in the United Kingdom.
