The Health Care Inspectorate (IHC) is involved in private hospitals and ZBC's. The reason is that more and more treatments take place outside the hospital, but also because there are clinics that do not meet the minimum standards.
In 2002, IHC started the investigation of the quality in healthcare in ZBC’s. Since 2009 health care institutions must also provide annual data. In April 2010 Contour Kliniek received its last (spontaneous) visit for investigation which was occurred positive.
