Assessment of Decision-Making Capacity in Healthcare

The assessment of decision-making capacity in healthcare entails a structured evaluation of an individual’s ability to make informed choices about their own treatment and care. Central to this process are the four standard criteria: the ability to understand relevant information, appreciate the consequences of options, reason about treatment choices and communicate a consistent decision. This functional approach has been embedded in legislation across multiple jurisdictions, emphasising a person-centred model that evaluates capacity for specific decisions at particular times. The global significance of capacity assessment spans psychiatric practice, geriatrics, genetics and palliative care, where clinicians must balance respect for autonomy with protective duties. Contemporary challenges include accounting for the influence of emotions and personal values, adapting assessments for cultural and cognitive diversity, and integrating emerging technologies without undermining the human judgement essential to nuanced evaluations. Practical applications range from guiding advance care planning to informing supported decision-making frameworks. Ongoing research seeks to refine assessment tools, standardise protocols and enhance training for professionals to ensure equitable and ethically robust determinations of capacity.
