Suicide in nurses.

The worldwide English language literature on suicide in nurses is reviewed in this article. There is evidence from several countries that female nurses are at increased risk of suicide. Very little information is available about the specific causes. Increased risk in nurses has been statistically associated with smoking and negatively related to extent of caffeine consumption. Unlike some other high-risk occupational groups, it is unclear to what extent access to means for suicide contributes to nurses' risk. The methodological issues and specific needs of research concerning suicide in nurses are discussed.
