Study design
STADPLAN (STudy on ADvance care PLANning in care dependent community dwelling older persons) was a multi-centre, two-arm cluster-randomised controlled, pragmatic trial with 12 months of follow-up. Clusters were defined as home care services and randomisation was carried out on cluster level in order to minimise contamination. Detailed information regarding the study protocol of the trial and the process evaluation can be found elsewhere.Ethical approval was obtained from the responsible authority in each centre.
