Abstract
Due la the limitations of standard epidemiological methods, indirect indicators have often been used to describe the characteristics of drug abusing populations and to assess prevalence trends in illegal drug use. In Barcelona (Spain), a study of emergency room (ER) attendance was carried out to describe the population of opiate/cocaine consumers across the whole city who use this service. Three thousand four hundred and five consumers of opiates and/or cocaine, aged 15‐44 years, who attended ERs during 1989, were identified. They accounted for 6807 episodes in the hospitals surveyed. Their mean age was 26 years, men (73%) being 1 year older than women (25.2 years). The drug of abuse was specified in the clinical records of 60% of individuals, heroin being the most frequently specified (56%). The main reason for attendance was ‘other medical condition’(OMC) (55% of episodes), followed by withdrawal (34%) and overdoses (6%). Seventy‐one percent of individuals were residents of Barcelona city, yielding a rate of 3.2 opiate/cocaine consumers attending ERs per thousand Barcelona residents aged 15‐44. The geographical distribution of the rates in the city showed a very large difference between districts, the most deprived ones having a higher rate of consumers attending ERs. ER data can provide valuable insights into the nature and dimensions of drug abuse problems.
