We confirm that alcohol intake and loss of tolerance are risk factors for death from heroin use, whereas no connection to heart pathology was observed. Further, prospective, studies should focus on other possible risk factors.

The 'high threshold programme' is safe as long as the patients remain in treatment and there are very few deaths due to leakage from the programme. However, there is a high mortality among those discharged from the programme and only a minority of the heroin users in Stockholm had applied for treatment.

The most important finding is that excess mortality among homeless men and women in Stockholm is entirely related to alcohol and drug abuse.

A cohort of 1640 hospitalized drug addicts was studied over an 8-year period, and consisted of 678 heroin users, 578 amphetamine users and 384 users of other drugs. In total, 234 addicts were HIV-positive, most of them heroin users. During the observation period, 214 deaths occurred in the cohort. The total mortality was 2.2% annually. Death linked to injection of heroin was the main cause of death not only among heroin users but also among subjects classified as users of amphetamines or other drugs. During the observation period, a total of 222 addicts (115 of whom were HIV-positive) entered the methadone programme. No deaths occurred among the HIV-negative subjects who were participating in the methadone programme. A total of 15 HIV-positive subjects died while taking part in the programme--13 of these subjects from natural causes (mostly HIV/AIDS).

BackgroundSeveral studies have concluded that some deaths classified as undetermined intent are in fact suicides, and it is common in suicide research in Europe to include these deaths. Our aim was to investigate if information on background variables would be helpful in assessing if deaths classified as undetermined intent should be included in the analyses of suicides.MethodsWe performed a register study of 31,883 deaths classified as suicides and 9,196 deaths classified as undetermined intent in Sweden from 1987 to 2011. We compared suicide deaths with deaths classified as undetermined intent with regard to different background variables such as sex, age, country of birth, marital status, prior inpatient care for self-inflicted harm, alcohol and drug abuse, psychiatric inpatient care, and use of psychotropics. We also performed a multivariate analysis with logistic regression.ResultsOur results showed differences in most studied background factors. Higher education was more common in suicides; hospitalization for self-inflicted harm was more common among female suicides as was prior psychiatric inpatient care. Deaths in foreign-born men were classified as undetermined intent in a higher degree and hospitalization for substance abuse was more common in undetermined intents of both sexes. Roughly 50% of both suicide and deaths classified as undetermined intent had a filled prescription of psychotropics during their last six months. Our multivariate analysis showed male deaths to more likely be classified as suicide than female: OR: 1.13 (1.07-1.18). The probability of a death being classified as suicide was also increased for individuals aged 15–24, being born in Sweden, individuals who were married, and for deaths after 1987–1992.ConclusionBy analyzing Sweden’s unique high-validity population-based register data, we found several differences in background variables between deaths classified as suicide and deaths classified as undetermined intent. However, we were not able to clearly distinguish these two death manners. For future research we suggest, separate analyses of the two different manners of death.

The liberalization of Sweden's drug policy correlated with an increase in maintenance treatment, a decrease in opiate-related mortality and inpatient care and an increase in deaths with methadone and buprenorphine in the tissues.

A 5-year follow-up study was performed on 82 homeless men, with mental problems, who had been contacted by an outreach team run by the Social welfare administration of Stockholm 1995/1996. Data have been collected from the Cause of Death Register, death certificates, forensic autopsy reports, hospital medical reports, Hospital Discharge Register, interviews with social workers and with those men who were able to participate. The standardized mortality ratio (SMR) was 4.7 times higher than expected. The highest mortality was found in the group where drug addiction was dominant; 46% had died. In the group of men with severe psychiatric disorders, with diagnosis such as schizophrenia, none had died. Compared with the others, they had spent less time in homelessness. Among the survivors, 75% were still homeless at the follow-up in spite of considerable treatment interventions from the social services and health authorities. Residential institutions or treatment seemed to have some protective effect concerning misuse, diseases and injuries. Among the still homeless, the mental health problems combined with substance use problems had increased with 17%. The life and housing situation for the whole group seemed not to have improved, even if fewer of them were staying in hostels for homeless people.

The death rate among illicit drug users was persistently high. Alcohol consumption was a contributing factor to premature death.
