Abstract
BACKGROUND : The study’s main aim was to assess the end-of-life decision-making
capacity and health-related values of older people with serious mental illness.
METHODS : A cross-sectional, observational study, was done at Weskoppies Psychiatric
Hospital, Gauteng Province, South Africa that included 100 adults older than 60
years of age and diagnosed with serious mental illness. The Mini-Cog and a
semi-structured clinical assessment of end-of-life decision-making capacity was done
before a standardized interview, Assessment of Capacity to Consent to Treatment,
was administered. This standardized instrument uses a hypothetical vignette to assess
decision-making capacity and explores healthcare-related values.
RESULTS : The Assessment of Capacity to Consent to Treatment scores correlated (p <
0.001) with the outcomes of the semi-structured decision-making capacity evaluation.
Significant correlations with impaired decision-making capacity included: lower scores
on the Mini-Cog (p < 0.001); a duration of serious mental illness of 30–39 years
(p = 0025); having a diagnosis of schizophrenia spectrum disorders (p = 0.0007); and
being admitted involuntarily (p < 0.0001). A main finding was that 65% of participants
had decision-making capacity for end-of-life decisions, were able to express their values
and engage in advance care discussions.
DISCUSSION AND CONCLUSION : Healthcare providers have a duty to initiate advance
care discussions, optimize decision-making capacity, and protect autonomous
decision-making. Many older patients with serious mental illness can engage in
end-of-life discussions and can make autonomous decisions about preferred end-of-life care. Chronological age or diagnostic categories should never be used as reasons for
discrimination, and older people with serious mental illness should receive end-of-life
care in keeping with their preferences and values.
