The gap in life expectancy from preventable physical illness in psychiatric patients in Western Australia: retrospective analysis of population based registers
Open accessAbstract
OBJECTIVE: To examine the mortality experience of psychiatric patients in Western Australia compared with the general population. DESIGN: Population based study. SETTING: Western Australia, 1985-2005. PARTICIPANTS: Psychiatric patients (292,585) registered with mental health services in Western Australia. MAIN OUTCOME MEASURES: Trends in life expectancy for psychiatric patients compared with the Western Australian population and causes of excess mortality, including physical health conditions and unnatural causes of death. RESULTS: When using active prevalence of disorder (contact with services in previous five years), the life expectancy gap increased from 13.5 to 15.9 years for males and from 10.4 to 12.0 years for females between 1985 and 2005. Additionally, 77.7% of excess deaths were attributed to physical health conditions, including cardiovascular disease (29.9%) and cancer (13.5%). Suicide was the cause of 13.9% of excess deaths. CONCLUSIONS: Despite knowledge about excess mortality in people with mental illness, the gap in their life expectancy compared with the general population has widened since 1985. With most excess deaths being due to physical health conditions, public efforts should be directed towards improving physical health to reduce mortality in people with mental illness, in addition to ongoing efforts to prevent suicide.

TL;DR
In Western Australia from 1985 to 2005, the life expectancy gap between psychiatric patients and the general population widened from 13.5 to 15.9 years for males and from 10.4 to 12.0 years for females. Most excess deaths were attributed to physical health conditions rather than suicide.
Key findings
- Among 292,585 psychiatric patients in contact with Western Australian mental health services between 1983 and 2007, of whom 47,669 died, the life expectancy gap increased from 13.5 to 15.9 years for males and from 10.4 to 12.0 years for females between 1985 and 2005.
- Overall, 77.7% of excess deaths were attributed to physical health conditions, including cardiovascular disease (29.9%) and cancer (13.5%); suicide accounted for 13.9% of excess deaths. Sex-specific results showed cardiovascular disease as the main cause of 26.2% of excess deaths in male psychiatric patients and 35.3% in female psychiatric patients, cancer for 13.6% in males and 13.3% in females, and suicide for 16.6% in males and 10.1% in females.
- The largest increases in the life expectancy gap were for other psychoses (14.8 to 22.7 years for males and 14.1 to 22.6 years for females) and stress or adjustment reactions (7.3 to 13.2 years for males and −0.2 to 9.3 years for females). Alcohol or drug disorders had the lowest life expectancy, with a gap exceeding 20 years at each time point.
- General population life expectancy increased from 73.1 to 79.1 years for males and from 79.3 to 83.8 years for females, while the gap for all mental disorders combined widened.
Methods
- Retrospective population-based record-linkage study in Western Australia using the mental health information system and death registrations; 292,585 people had contact with mental health services between 1983 and 2007, with 47,669 deaths, and results covered 1985–2005.
- The primary cohort used an “active” case definition: people with ongoing contact with mental health services or contact in the preceding five years. Life expectancy at birth was calculated with abridged life tables using five-year age groups and five-year death windows, then compared with Western Australian population life tables.
- Excess mortality by cause was calculated as observed deaths minus expected deaths, with expected deaths derived from Western Australian cause-specific death rates by age group, sex, and time period applied to cohort person-years; analyses used SAS.
Limitations
- The paper states reliance on administrative data of contacts with services: not all people with mental illness have contact with services, and the register excludes people with undiagnosed or untreated disorders and those treated only by general practitioners or private psychiatrists and psychologists.
- The paper states that changes in service delivery and diagnostic practices could influence life expectancy trends, and that changes in cause-of-death coding over time could affect cause-specific excess estimates; for example, HIV has been coded as a cause of death in Australia only since 1996, and ICD-10 replaced ICD-9 from 1999, though an Australian Bureau of Statistics analysis suggested little impact on rates.
- Evident from the design: this is an observational record-linkage study, so it cannot establish causality, and the paper does not report individual-level adjustment for potential confounders such as socioeconomic status, lifestyle factors, or medication effects.

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.
Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-10.
Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-10.
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.
