Ethical and legal issues - medicolegal considerations and legal framework regarding care of the older person

The frameworks

Legal frameworks specific to the older person span substitute decision-making (guardianship, enduring power of attorney), advance care directives, and elder abuse protections - each with jurisdiction-specific detail but shared underlying principles across Australian states/territories
Loss of decision-making capacity (from dementia, delirium, or acute illness) is common in the population geriatric medicine serves, making these legal frameworks routinely, not exceptionally, relevant to everyday practice

Enduring power of attorney/guardian - a person appointed (by the patient while they had capacity, or by a tribunal if not) to make decisions on the patient's behalf once capacity is lost - financial and medical/personal decision-making powers are often separate appointments
Advance care directives - a patient's own documented wishes about future treatment, made while they had capacity, which take precedence over a substitute decision-maker's contrary view where validly made and applicable to the situation at hand
Elder abuse (physical, financial, psychological, neglect) - clinicians have a professional (and in some circumstances legal) responsibility to recognise and respond to suspected abuse, which disproportionately involves a family member or carer as the perpetrator

When capacity is in question, formal assessment (see assessment of capacity) determines whether the patient can make the specific decision at hand - capacity is decision-specific and time-specific, not a global, permanent label
Establishing who holds legal decision-making authority (and for which domain - financial vs medical/personal) is an essential first step whenever a patient lacks capacity for a given decision

Document advance care directives clearly and make them accessible across care settings (a directive that exists but cannot be found at the point of need is of little practical use)
Suspected elder abuse should prompt escalation via appropriate safeguarding pathways, balanced against the patient's own autonomy where they have capacity and do not wish to pursue a particular response

Guardianship tribunals, enduring power of attorney, advance care directives, elder abuse and neglect

These frameworks exist to protect the older person's autonomy and interests when they cannot advocate fully for themselves - they should be applied as tools to support the patient's own wishes wherever they can be ascertained, not simply as an administrative or protective override
