Summary
Patients surviving deliberate self-poisoning face significantly increased mortality risk, particularly from suicide. Key predictors for death include older age and male sex, highlighting the need for ongoing clinical attention.
Area of Science:
- Public Health
- Epidemiology
- Psychiatry
Context:
- A 15-year follow-up study examined mortality in patients who survived deliberate self-poisoning.
- The cohort comprised 152 females and 101 males initially treated in 1978.
- Follow-up extended to the end of 1993.
Purpose:
- To investigate long-term mortality rates and identify factors associated with death in survivors of self-poisoning.
- To compare observed mortality with expected rates in the general population.
- To determine specific predictors for all-cause mortality and suicide mortality.
Summary:
- Overall mortality was significantly elevated: 4.5 times expected for females and 3.6 times for males, highest in the first five years.
- Mortality ratios were highest for suicide (61.1x for females, 38.8x for males).
- Increased mortality was also observed for cardiovascular diseases in females and respiratory diseases in males.
Impact:
- Older age (≥30 years) and male sex were significant predictors for all-cause mortality.
- Imprisonment emerged as a protective factor against death (RR=0.2).
- Predictors for suicide included older age, male sex, and psychiatric assessment of a serious attempt, indicating complex risk factors.
