Suicide and Schizophrenia: A Review of Literature for the Decade (1990-1999) and Implications for Mental Health Nursing

Abstract

This paper presents an overview of recent evidence on general and specific risk factors for suicide in patients with schizophrenia. The authors highlight the significant factors contributing to the likelihood of suicide in patients diagnosed with schizophrenia. This information will enhance the delivery of nursing care to these patients in all health care settings. A review of literature was conducted by two methods of investigation: Medline and CINAHL search and a manual search through articles from 1990 to 1999. The lifetime risk of committing suicide is estimated at about 9-13% of persons with schizophrenia, and it is 20 to 50 times higher than that in the general population. Young white males diagnosed with schizophrenia who are depressed, unmarried, unemployed, socially isolated, and functionally impaired and who lack external support are the most vulnerable in the early stages of schizophrenic illness. Findings can be instrumental in identifying and treating patients who are most vulnerable and in making psychiatric nurses aware of the scenarios and critical stages of the disease process when suicide is most likely to occur.
