Drug-related deaths between 1985 and 1992 examined at the Institute of Forensic Medicine in Vienna, Austria.

Considering the official figure on drug-related deaths in Austria, the problem of substance abuse has dramatically worsened over the last years. There is a distinct lack of comprehensive information concerning drug-related deaths in Austria, although deaths of drug users may be potentially important indicators of the extent of drug-related problems in the population. The results of examinations performed on 372 deceased substance abusers at the Institute of Forensic Medicine in Vienna between 1985 and 1992 are presented. Drug-related deaths are defined according to the official definition issued by the Austrian Federal Ministry of Internal Affairs. A distinction was made between injecting drug users and non-injecting drug users with respect to infectious diseases transmitted by sharing of paraphernalia. Between 1985 and 1992 there was a distinct increase in drug-related deaths. In approximately 30% an accidental single substance intoxication, mainly due to morphine, was found. A connection with a better quality of street drugs is assumed but not proven. In 207 corpses more than one drug, including alcohol, was detected. During the investigation there was an evident trend towards multi-substance abuse patterns. Furthermore, blood alcohol concentration, an additional risk factor for narcotic overdose, was strongly associated with higher age. The small number of examined drug injectors found positive for the human immunodeficiency virus type-1 (HIV-1) makes it difficult to draw any kind of conclusion regarding the HIV-I seroprevalence among injecting drug users in Vienna.
