Ethics and Dissemination: This trial is pending ethics approval from Research Ethichs Comite for North Denmark Region. The findings from this randomised controlled trial will be disseminated through peer-reviewed journals, national and international conferences and will be utilised as health care political decision making for the future national accreditation programme. In addition, the results will facilitate to validate the effect of unannounced hospital surveys; given the issues of currently meeting an "arranged reality" during hospital surveys, this seems extremely desirable.
