Ethical and legal issues - ethics of managing older patients

The tensions

Managing older patients raises recurring ethical tensions between autonomy (respecting the patient's own choices, even unwise ones), beneficence/non-maleficence (acting in the patient's best interest, avoiding harm), and justice (fair allocation of limited healthcare resources) - resolved case-by-case rather than by a fixed hierarchy
These tensions arise across nearly every geriatric presentation - from a cognitively intact patient declining a clearly beneficial treatment, to decisions about treatment intensity in advanced dementia, to resource allocation in residential care

Ageism (conscious or unconscious) can distort ethical reasoning in both directions - either withholding beneficial treatment on the basis of age alone, or imposing burdensome treatment because a younger patient's standard pathway is applied reflexively without adjustment for the older patient's actual goals and prognosis
A cognitively intact patient retains the right to make decisions others consider unwise (autonomy is not conditional on making the "right" choice) - the ethical obligation is to ensure the decision is genuinely informed, not to override it because the clinician disagrees

Formal capacity assessment (see assessment of capacity) is the threshold ethical/legal question whenever a decision appears to conflict with the patient's apparent best interest - autonomy applies fully once capacity is confirmed, and substitute decision-making principles apply if it is not

Substitute decision-making (when capacity is lacking) should apply the substituted judgement standard (what the patient themselves would have wanted, based on their known values) rather than the best interests standard as the primary approach where the patient's prior wishes are known - best interests is used when substituted judgement cannot be determined
Multidisciplinary and, where needed, formal ethics consultation supports genuinely difficult cases rather than leaving the decision to a single clinician in isolation

Capacity assessment, substitute decision-making, advance care directives, resource allocation in aged care

Ethical practice in geriatric medicine requires actively counteracting the pull toward either therapeutic nihilism (withholding appropriate care because of age) or therapeutic excess (imposing burdensome care because it is available) - neither default is ethically sound, and the correct answer is case-specific
