[Epidemiology of acute poisoning: a study of 851 cases detected in the southern area of the Madrid community in 1990].

Epidemiology of acute intoxication (AI) must be reviewed periodically to know its trends, therefore, following a line of RESEARCH, we have studied the AI's attended on the Emergency Ward of Internal Medicine at Hospital Doce de Octubre (Madrid). We found that most of them are voluntary (93%): in females being predominant the suicide attempt and in males the AI secondary to illegal drugs use. Toxic drugs have been used in 96% on suicide attempts; the relative incidence of each drug does not vary, but AI with more than one toxic diminish. Within the non-drug toxics, illegal drugs come first, followed by alcohol. Drug-addiction is the numerically most frequent antecedent; depression is predominant in suicide attempts, alcoholism is infrequent in ethyl AI. ICU admissions represent an intermediate figure in our country, mortality (most of them due to overdose) is similar to those of non-Spanish series.
