Open Dialogue (OD) is a method of treating people who have experienced psychosis. It was created in Finland and is gaining interest in many countries. It is an alternative approach to traditional psychiatric treatment, its aim is to deal with the healing process of the person, instead of focusing on the illness. Studies conducted so far indicate high effectiveness of OD in shortening the duration of hospitalization, reducing the dose of neuroleptic drugs and the risk of social exclusion. The article reviews studies on attempts to implement OD in various countries, focusing on the difficulties that arise in this process. The most common challenges were financial costs, adaptation to all patients, difficulties related to ensuring mobility, creating cooperation between specialists and a shortage of staff. Then, reference was made to the situation in Poland, where the Polish Open Dialogue Institute (PIOD) has been operating since 2011 and Mental Health Centers (CZP) have been developed since 2018. It seems that the experiences of various countries in implementing the OD method may be valuable in the process of developing the CZP, especially since the experiences of PIOD indicate that the OD methods are effective not only in working with people with experience of psychosis.
