The present trial is designed by IKAS and the Danish Center for Healthcare Improvements (DCHI) to inform a decision whether or not to implement unannounced accreditation surveys in the 3rd version of the DDKM in 2016. In September 2013, the IKAS Board of Directors decided to approve and finance the project, and it is expected that the results from the present trial will be available for the Board's decision in 2015.
