This is a complex intervention involving action research and the study is registered first after the completion of the educational intervention and on-ward implementation of PCPC. The implementation process has been dynamic and varied at the four different wards involved in the project. The duration of the implementation period was considerably longer than anticipated. This is in part related to high staff turnover, serious lack of psychiatrically trained RNs, as well as other barriers to implementation. Barriers have slowly been overcome by changes in routines instigated from within the care staff (as opposed to being imposed on staff from "above"). While the long implementation process can be seen as a limitation, it's interactive nature can at the same time be construed as a strength, as change from within can be expected to increase sustainable change.
