Death and suicide among former child and adolescent psychiatric patients

BackgroundIncreased mortality rates among previous child and adolescent psychiatry (CAP) patients have been found in Scandinavian studies up to the 1980s. The suicide risk in this group has been estimated to be almost five times higher than expected. This article addresses two questions: Do Swedish CAP patients continue to risk premature death and what kind of information related to psychiatric symptoms and/or behavior problems can predict later suicide?MethodsHospital files, Swedens census databases (including immigration and emigration) and administrative databases (including the Swedish Hospital Discharge register and the Persons Convicted of Offences register), and the Cause of Death register were examined to determine the mortality rate in a group of 1,400 former CAP inpatients and outpatients over a period of 12–33 years. Observed and expected numbers of deceased were calculated with the prospective method and the standardized mortality ratio (SMR) method. The relative risk or the risk ratio (RR) is presented with 95% confidence intervals (CIs). Significance level tests were made using two-by-two tables and chi-square tests. The Cox proportional-hazards regression model was used for survival analysis.ResultsTwenty-four males and 14 females died. Compared with the general population, the standardized mortality ratio in this group of CAP patients was significantly higher in both sexes. Behavioral problems, school problems, and co-morbid alcohol or drug abuse and criminality (including alcohol-related crimes) were found to be important predictors. Thirty-two deaths were attributed to suicide, intoxication, drug overdose, or accident; one patient died of an alcohol abuse-related disorder, and five patients died of natural causes. Suicide was the most common cause of death, but only 2 of these 19 cases were initially admitted for attempted suicide.ConclusionWe suggest that suicide and death prevention among CAP patients may not be a psychiatric issue per se but a future function of societys juvenile social-welfare investments and juvenile-delinquency prevention programs.

Child and adolescent psychiatric patients and later criminality

BackgroundSweden has an extensive child and adolescent psychiatric (CAP) research tradition in which longitudinal methods are used to study juvenile delinquency. Up to the 1980s, results from descriptions and follow-ups of cohorts of CAP patients showed that childrens behavioural disturbances or disorders and school problems, together with dysfunctional family situations, were the main reasons for families, children, and youth to seek help from CAP units. Such factors were also related to registered criminality and registered alcohol and drug abuse in former CAP patients as adults. This study investigated the risk for patients treated 1975–1990 to be registered as criminals until the end of 2003.MethodsA regional sample of 1,400 former CAP patients, whose treatment occurred between 1975 and 1990, was followed to 2003, using database-record links to the Register of Persons Convicted of Offences at the National Council for Crime Prevention (NCCP).ResultsEvery third CAP patient treated between 1975 and 1990 (every second man and every fifth woman) had entered the Register of Persons Convicted of Offences during the observation period, which is a significantly higher rate than the general population.ConclusionResults were compared to published results for CAP patients who were treated between 1953 and 1955 and followed over 20 years. Compared to the group of CAP patients from the 1950s, the results indicate that the risk for boys to enter the register for criminality has doubled and for girls, the risk seems to have increased sevenfold. The reasons for this change are discussed. Although hypothetical and perhaps speculative this higher risk of later criminality may be the result of lack of social control due to (1) rising consumption of alcohol, (2) changes in organisation of child social welfare work, (3) the school system, and (4) CAP methods that were implemented since 1970.

Mood Disorders in Childhood and Adolescence and Their Outcome in Adulthood

In this chapter occurrence of mood disorders in a child and adolescent psychiatric population and among patients visiting a youth psychiatric clinic for young adults in a smaller county council and province study area in Sweden is described. It also describes the outcome in adulthood for patients having mood disorder in childhood and adolescence in terms of later general psychiatric care and diagnoses, mortality and criminality.
