Suicide prevention: nursing intervention.

A new era has begun in the field of psychiatric-mental health nursing. There is a trend for psychiatric-mental health nursing to move away from the medical model to the psychosocial model and focus more on the promotion of mental health and the prevention of mental illness. Literature reflects an abundance of evidence of the fact that nurses have responded to the many changing health needs, especially with respect to redefinition and expansion of their roles in hospitals, clinics, day care facilities, and the community. Nurses have been urged to test the effectiveness of their interventions.1
