By use of the computerized, nationwide psychiatric case register in De
nmark, 3 cohorts of psychiatric patients hospitalized for at least one
year in 1972, 1977 and 1982, respectively, were identified and follow
ed until April 1, 1988, regarding cause of death. A decline in overall
excess mortality compared with the general population was seen from t
he 1972 cohort to the 1982 cohort irrespective of sex, age group and d
iagnosis. To analyse cause of death, 298 long-stay patients at Aarhus
Psychiatric Hospital were followed for 5.5 years. Lung diseases caused
the highest excess mortality. The authors emphasize that risk of deat
h in long-stay patients below 50 years of age is still fourfold compar
ed with the general population and point to the necessity of improving
medical care.
