Abstract

Risk assessment is a core skill in psychiatry. Risk prediction for suicide in schizophrenia is known to be complex. We undertook a systematic review of all original studies concerning suicide in schizophrenia published since 2004. We found 51 data-containing studies (from 1281 studies screened) that met our inclusion criteria, and ranked these by standardized quality criteria. Estimates of rates of suicide and risk factors associated with later suicide were identified, and the risk factors were grouped according to type and strength of association with suicide. Consensus on the lifetime risk of suicide was a rate of approximately 5%. Risk factors with a strong association with later suicide included being young, male, and with a high level of education. Illness-related risk factors were important predictors, with number of prior suicide attempts, depressive symptoms, active hallucinations and delusions, and the presence of insight all having a strong evidential basis. A family history of suicide, and comorbid substance misuse were also positively associated with later suicide. The only consistent protective factor for suicide was delivery of and adherence to effective treatment. Prevention of suicide in schizophrenia will rely on identifying those individuals at risk, and treating comorbid depression and substance misuse, as well as providing best available treatment for psychotic symptoms.

  • The absence of a single reported instance of suicide across the 39 studies and 2076 participants is surprising given the high rates of suicide in this population.

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.
