This article examines a detailed investigation of 764 cases of completed suicide in London. Each suicide was classified into 2 categories: suicide with or without a history of previous attempts. Results show that 60 percent of the men & 80 percent of the women had received medical care. The author concludes that doctors should act as spotters in recognizing suicidal behavior. In addition, the prescribing of medication should be carefully monitored for fear of a potential overdose. (10 Refs.)
