This review is describing different models of case management, showing their similarities and differences with regards to the way they operate. Good relationship between patient and case manager, application of the biopsychosocial model, availability of psychosocial treatment methods and rehabilitation programs, and individual treatment plan are all important factors in case management's success. Large number of studies supports the application of case management in practice as effective treatment method in treating people with severe mental disorder, particularly those, who are less co-operative. Therefore, the implementation of case management into psychiatric practice should be supported.
