The somatic care of HIV-infected intravenous drug abusers (IVDUs) is often combined with many problems. The addict is often an unpopular patient, but society must assume responsibility for him or her and it is important to solve care problems in an appropriate way. This study was undertaken in order to investigate what kind of care addicts want when they become somatically ill. A questionnaire was given to patients who acquired HIV infection due to intravenous drug abuse, who visited an outpatient clinic for HIV-infected patients at the Department of Infectious Disease, Huddinge Hospital, Stockholm, Sweden. A total of 72 of the original 78 questionnaires could be evaluated. Thirty respondents took part in the Stockholm Methadone Programme. The patients were asked to rank the importance of professional competence among the staff. The patients ranked competence in pain treatment highest followed by competence in somatic medical care. Lower ranked, but still perceived as important, was competence in psychiatric medical care and social welfare work. Experience in treatment of addiction was ranked as less important. It can be concluded that it is fruitful to ask IVDUs about their preferences concerning care.
