A Systematic Review of Mortality in Schizophrenia: Is the Differential Mortality Gap Worsening Over Time?

Saha, Sukanta, Chant, David, McGrath, John·2007·Archives of General Psychiatry

Abstract

CONTEXT: Despite improvements in mental health services in recent decades, it is unclear whether the risk of mortality in schizophrenia has changed over time. OBJECTIVE: To explore the distribution of standardized mortality ratios (SMRs) for people with schizophrenia. DATA SOURCES: Broad search terms were used in MEDLINE, PsychINFO, Web of Science, and Google Scholar to identify all studies that investigated mortality in schizophrenia, published between January 1, 1980, and January 31, 2006. References were also identified from review articles, reference lists, and communication with authors. STUDY SELECTION: Population-based studies that reported primary data on deaths in people with schizophrenia. DATA EXTRACTION: Operationalized criteria were used to extract key study features and mortality data. DATA SYNTHESIS: We examined the distribution of SMRs and pooled selected estimates using random-effects meta-analysis. We identified 37 articles drawn from 25 different nations. The median SMR for all persons for all-cause mortality was 2.58 (10%-90% quantile, 1.18-5.76), with a corresponding random-effects pooled SMR of 2.50 (95% confidence interval, 2.18-2.43). No sex difference was detected. Suicide was associated with the highest SMR (12.86); however, most of the major causes-of-death categories were found to be elevated in people with schizophrenia. The SMRs for all-cause mortality have increased during recent decades (P = .03). CONCLUSIONS: With respect to mortality, a substantial gap exists between the health of people with schizophrenia and the general community. This differential mortality gap has worsened in recent decades. In light of the potential for second-generation antipsychotic medications to further adversely influence mortality rates in the decades to come, optimizing the general health of people with schizophrenia warrants urgent attention.

  • Research into the health effects of recession has suggested that consequences will be most severe for the poorest groups in society and will have the most impact where social safety-nets are lacking and public hardship grows rapidly.

  • Cause-specific SMRs for schizophrenia were higher than 1 except for cerebrovascular disease, which was based on only three studies.

    “An elevated mortality rate among persons with schizophrenia was indicated by cause-specific SMRs that were higher than 1, except for the SMR for cerebrovascular disease, which was based on only three studies.”

  • SMRs for schizophrenia increased significantly during the seventies, eighties, and nineties: from 1.84 to 2.98 to 3.20.

    “Another interesting result was that the SMRs increased significantly during three recent decades, i.e., the seventies, eighties, and nineties; from 1.84, to 2.98, to 3.20, respectively.”

  • The risk of suicide is approximately 13-fold higher for persons with schizophrenia compared to the general population.

    “a recent meta-analysis estimated that the risk of suicide was approximately 13-fold higher for persons with schizophrenia as compared to the general population (Saha et al. 2007).”

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.
