Background: Both mental illness and criminality are associated with higher risk of early death,
yet the mortality among forensic psychiatric patients who are affected by both mental illness
and criminal behaviour has scarcely been studied. Aims: To analyse the mortality among all
patients who were committed to a compulsory forensic psychiatric hospital treatment in Finland
between 1980 and 2009. Mortality was analysed according to the age when the patient was
committed to forensic treatment. Results: A total of 1253 patients were included, of which 153
were females and 1100 were males. The mean follow-up time in this study was 15.1 years, and
351 (28%) had died during the follow-up period. The standardized mortality rate (SMR) for the
whole study group was 2.97 (95% CI 2.67–3.29). Among females the SMR was 3.62 (95% CI
2.57–5.09), and among males 2.91 (95% CI 2.61–3.25). The SMRs were higher when patients
were committed to forensic treatment before the age of 40 years. Conclusion: This study
showed an increased mortality among forensic psychiatric patients compared with the general
population and the mortality was inversely proportional to the age when the treatment had
begun. In contrast to the earlier studies, the mortality in this study was lower indicating that
prolonged treatment may have an overall protective effect on forensic psychiatric patients.

M
ortality among psychiatric patients is known to be
higher than the general population (1), and patients
who are admitted to hospital for a mental disorder in
Denmark, Finland and Sweden have a two- to threefold
higher mortality than the general population (2). Finnish
patients with schizophrenia between the ages of 20 and
40 had 17.0–22.5 years less life expectancy when com-
pared with the general population (3). Discharged adult
prisoners have a 5–10 times higher mortality when com-
pared with an age-matched population in Finland, and in
2002, the mean age of death was 45 years for those with
a prior criminal act (4).
Only a few scientific articles have been published on
the mortality of the forensic patients who are affected by
both mental illness and criminal behaviour, both of
which appear to be associated with a higher risk of early
death. In Sweden, 400 subjects aged 15–29 years were
found to be mentally abnormal in a forensic psychiatric
examination conducted between 1951 and 1954, and
subsequently followed for approximately 20 years (5).
Forty-three of those subjects had died during the study
period, which was three times the expected mortality in
the average population. One hundred subjects in that
study had been designated “insane” and 11 of them had
died during the study period, which was four times
the expected mortality when compared with the average
population. In another Swedish study, 46 subjects who
had been in forensic treatment because of serious mental
disorder were followed after their discharge during a
study period of 1992–1999 (6). The median follow-up
time was 53 months (range 0–93 months) and five subjects
died during the follow-up, which gave a standardized
mortality rate (SMR) of 13.4 (95% CI 4.35–31.3). Subjects
from that study were also involved in another study of
88 forensic patients that were discharged in Sweden dur-
ing 1992–2007 (7). These subjects were followed until
the end of 2008, and 20 died during the follow-up time,
which gave a SMR of 10.4 (95% CI 6.4–16.1). The
SMR for males was 9.2 (95% CI 5.3–14.8; 17 deaths),
and for females 40.5 (95% CI 8.3–118.3; three deaths).
Aims
Earlier research into forensic patients’ mortality primarily
suffers from antiquity as well as small sample sizes and
subsequently large confidence intervals. Therefore, it
