Mortality in a Cohort of Patients with Schizophrenia: A Record Linkage Study*
Abstract
A retrospective study of mortality was conducted in which 3,623 patients with schizophrenia receiving treatment in Alberta between 1976 and 1985 were followed to the end of 1985. Vital status was determined by record linkage to the Statistics Canada Mortality Data Base. There were 301 deaths in the cohort, 97 of which were due to suicide. For all causes of death combined, the risk of mortality was approximately double that of the Alberta population; for suicide, risk was increased by a factor of 20. Mortality from circulatory, respiratory, digestive and genitourinary diseases was also greater than expected. It is estimated that those who suffer from schizophrenia have a life expectancy which is approximately 20% shorter than that of the general population. This study confirms earlier research demonstrating an increased risk of mortality associated with schizophrenia, and extends those findings to specific causes of death.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
