Mental health nurses working purposefully with people with serious and enduring mental illness--an international perspective.

There has been a world-wide refocus on people with serious and enduring mental health problems. This has provided major challenges for all those involved in mental health care, as the last two decades have produced radical changes in service delivery and a range of new interventions. Mental health nurses are playing a central role as community based clinical case managers and are beginning to use a range of psychosocial interventions. They are also revitalizing skills in the more traditional areas of medication management and residential care. In addition, there are growing problems of substance abuse and violence which needs to be addressed. Mental health nursing is responding in this new era by various training initiatives. However, these programmes need rapid expansion as mental health nurses will continue to play a key role in the services of the future and therefore need these new skills.
