Reflections on mental capacity assessments in general hospitals

Area of Science:

• Medicine
• Psychiatry
• Bioethics

Background:

• Assessing decision-making capacity in general medical inpatients is crucial for ethical treatment.
• Mental disorders can significantly impair a patient's ability to understand and weigh risks associated with healthcare decisions.

Observation:

• Two cases are presented from non-psychiatric settings involving patients with established mental disorders.
• In both instances, the patients' presentations masked the influence of their mental disorder on their capacity to consent to or refuse life-sustaining treatment.

Findings:

• A significant proportion of general medical inpatients may lack capacity to make treatment decisions.
• Clinicians may not recognize impaired decision-making capacity, even with a known history of mental disorder.
• Mental disorders can subtly inhibit the ability to weigh risks when refusing potentially life-sustaining interventions.

Implications:

• There is a need for increased vigilance among healthcare professionals in assessing decision-making capacity in all inpatients.
• Improved recognition of how mental disorders affect capacity is essential for providing appropriate and ethical care.
• Failure to recognize impaired capacity can lead to inappropriate treatment refusal or acceptance, impacting patient outcomes.
