The suicide of a patient can be devastating to the family and to the family physician. The patient's death may shake the physician's confidence, undermine any willingness to work with patients with a mental illness, and provoke professional and legal review. In an attempt to help the family physician prevent suicide, this article reviews known risk factors and offers a strategy for assessing these factors in individual patients. The authors outline interventions that fit the existing level of risk and provide suggestions for the physician in the event of a completed suicide.
