In a psychiatric/ecological study, the authors investigated which aspects o
f a town district would provide an explanation to the fact that alcoholics
are treated above average in addiction-psychiatric wards in a given city di
strict, while in other districts treatment is carried out in internal medic
al wards. The research was based on data collected between 1988 and 1994 fr
om approximately 77% of all patients suffering from alcohol and legal drug
abuse (n = 15,473) in 41 hospitals in Hamburg. It was established that in s
omatic departments, mainly internal medicine, 70% of male and 67% of female
patients were admitted for alcohol and legal drug abuse. The results of a
geographical analysis of hospitalization risks showed that the addiction-ps
ychiatric facilities of psychiatric wards are mainly utilized by inhabitant
s from nearby districts. Risks of above-average hospitalization for alcohol
ics and legal drug abusers in internal wards, as well as insufficient addic
tion-psychiatric care, are to be expected in town districts where a shortag
e of psychiatrists exists, and where the unemployment rate is high. In thes
e crucial areas, addiction-specific facilities, such as qualified programs
for detoxication or techniques for short intervention, should be establishe
d within the framework of an addiction-specific liaison service in general
hospitals. Copyright (C) 2000 S. Karger AG, Basel.
