🧠 Cognitive Impairment & Legal Orders
A guide for Australian nursing students — understanding cognitive impairment, assessing decision-making capacity, legal documentation, SACAT Section 32 Special Powers, and keeping wandering patients safe.
🧠 What is Cognitive Impairment?
Cognitive impairment refers to difficulties with memory, thinking, reasoning, language, or executive function that affect a person's ability to carry out everyday activities or make decisions. In the clinical setting, you will most commonly encounter three main causes:
- Progressive and usually irreversible
- Affects memory, language, behaviour, judgment
- Types: Alzheimer's (most common), Vascular, Lewy body, Frontotemporal
- Gradual onset over months to years
- Capacity may fluctuate early; typically declines over time
- Consider communication adaptations — short sentences, visual cues, familiar faces
- Acute onset — hours to days
- Fluctuating consciousness, disorientation, agitation or hypoactivity
- Usually reversible with treatment of the underlying cause
- Common causes: infection, medications, pain, urinary retention, constipation, dehydration, post-op
- Use 4AT or CAM screening tools
- Non-pharmacological management first: reorient, familiar environment, mobility
- Occurs after birth — stroke, TBI, hypoxia, infection
- Variable deficits depending on injury location and severity
- May affect memory, attention, impulse control, language
- Can be stable or improving with rehabilitation
- Capacity assessment is essential — deficits are often domain-specific
- Collaborate with OT, speech pathology, neuro rehab
⚖️ Assessing Decision-Making Capacity
When assessing whether a person can make a specific decision, four functional abilities must be present:
When a person lacks capacity, the SDM is determined in this order (first available and willing person):
- Person appointed under a valid Advance Care Directive (ACD) as substitute decision-maker
- Person appointed under a valid Enduring Power of Attorney (EPA) or Enduring Power of Guardianship (EPG) — if the powers apply to healthcare/personal decisions
- Spouse or domestic partner (if in close and continuing relationship)
- Adult carer (unpaid, caring for the person at the time)
- Adult relative — in order of closeness: parent, child, sibling, grandparent, grandchild, aunt/uncle, nephew/niece
- If no SDM is available or willing → refer to SACAT / Public Advocate
📄 Legal Documents — ACD, POA & POG
- A legal document made under the Advance Care Directives Act 2013 (SA)
- Allows a person to record their wishes, values, and goals for future healthcare
- Can appoint a substitute decision-maker (SDM)
- Can include binding refusals of treatment (must be followed even if the person would die as a result)
- Must be made while the person has decision-making capacity
- Must be witnessed by an authorised witness (e.g. health practitioner, lawyer)
- Supersedes family preferences when in conflict — the ACD takes priority
- Check My Health Record and hospital documentation for existing ACDs
- A legal document appointing a trusted person (the attorney) to make financial and/or property decisions
- In SA, a financial EPA does not extend to personal/healthcare decisions unless specifically drafted to include them
- Must be registered with the SA Lands Titles Office to be used for real estate transactions
- Ceases on death
- Nursing note: A financial EPA does not automatically give authority over medical decisions — check what the document actually authorises
- The Advance Care Directive is the correct document for healthcare SDM authority in SA
- Appoints a guardian to make personal/lifestyle decisions when the person lacks capacity
- In SA, governed by the Guardianship and Administration Act 1993 (SA)
- Powers include: where the person lives, what health care they receive, who they associate with
- Must be witnessed and signed while the person has capacity
- Activated only when the person lacks decision-making capacity
- The guardian must act in the person's best interests and consistent with their known wishes/values
- Check My Health Record and the patient's medical record for uploaded ACD/EPA/EPG
- Ask the patient (while they have capacity) if any documents exist
- Ask family/next of kin — but note family cannot override a valid ACD
- Contact the ACD Registry (SA Health) if needed
- If documents cannot be found, document your attempts and escalate
- Notify the treating team and social worker if there are concerns about decision-making capacity
⚖️ SACAT — Section 32 Special Powers
What it does: Authorises the use of physical force (or direction) to carry out medical or dental treatment for a person who lacks decision-making capacity and is refusing or unable to consent.
- Applied when a person refuses necessary treatment and there is no SDM able to consent
- Examples: wound care, administration of essential medications, IV access, investigations
- The treatment must be in the person's best interests
- SACAT appoints a guardian with authority to consent, or the Tribunal itself authorises the treatment
- Nursing role: Document refusal behaviours accurately; provide care compassionately within the authorised scope; use minimum necessary force; prioritise dignity
What it does: Authorises the use of force or restriction to place a person in, or prevent them from leaving, a particular place — such as a residential aged care facility (RACF), hospital ward, or memory support unit.
- Used when a person is at risk of harm if they leave their current environment
- Examples: person with advanced dementia who wanders into danger, refusing hospital discharge to safe place
- The accommodation must be the least restrictive option appropriate for their needs
- SACAT appoints a guardian with authority over accommodation decisions
- Nursing role: Understand the order's scope — what restrictions are permitted; ensure care environment is as normalised as possible; document incidents of attempted elopement
What it does: Authorises the use of physical force or mechanical restraint when necessary to carry out treatment or maintain the person's safety or the safety of others, in conjunction with a 32(a) or 32(b) order.
- This is the most significant intervention — it directly restricises bodily autonomy
- Restraint must be the least restrictive option; all alternatives must have been trialled
- Examples: soft limb restraints to prevent IV removal, enabler beds, restrictive clothing
- Must be regularly reviewed and documented — restraint is never indefinite
- Chemical restraint (sedation) requires medical authorisation and is separate from physical restraint
- Nursing role: Check regularly (every 30 min minimum); assess circulation, skin integrity, distress; document rationale and observations; de-escalate and remove restraint as soon as safe to do so; ensure family are informed
🚫 Reducing Restraint
"Restraint is the restriction of an individual's freedom of movement."
— Australian Commission on Safety and Quality in Health Care (ACSQHC)
It includes mechanical restraint (physical devices), physical restraint (hands-on force), and chemical/pharmacological restraint (medication whose primary purpose is to sedate or control behaviour).
Things that count as restraint — these may not always look like restraint, but legally they are:
✓ What Can We Do to Reduce Restraint?
- Understand the benefits, indications and risks of common psychotropic medications — what to use and when
- Identify and manage withdrawals — nicotine, alcohol, opioids, benzodiazepines
- Use accurate pain assessment tools — PAIN-AD scale for non-verbal patients
- Use analgesia as first line if the patient has a known painful condition (e.g. fracture, wound) — unmanaged pain is a common driver of agitation
- Chemical restraint should only be used when a patient is a risk to themselves or others and other measures have failed
- Attend Safety Intervention / de-escalation training at your facility
- Understand non-verbal communication — behaviour is often communication
- Identify early signs of agitation — intervene before escalation
- Use a calm voice, non-threatening posture, and give the person space
- Offer choices and validate feelings — "I can see you're frustrated"
- Involve family or familiar people — their presence can significantly reduce distress
- Prompt and comprehensive discharge planning — prolonged hospital stays increase restraint risk
- Multi-disciplinary discussions — involve nursing, medical, allied health, social work
- Have open conversations with family — discuss expectations, concerns, and options
- Know your support options: Code Black, Security Assist, AIN/carer specials, PAO
- Consider ITOs or SACAT orders through the appropriate team when clinically indicated
- Foster a culture where patient care is the priority — not staff convenience
- Speak up if you see restraint being used inappropriately — it is your professional obligation
- Access staff psychological support — managing agitated patients is emotionally demanding
- Debrief after difficult incidents with your manager, peers, or EAP
- Familiarise yourself with Australian national standards and SA Health guidelines on minimising restrictive practices
🔒 Detention Orders
Detention orders are distinct from SACAT guardianship orders and arise under mental health legislation when a person poses a risk to themselves or others due to a mental illness.
- Allows police or health practitioners to take a person to an approved hospital for assessment
- Does not authorise ongoing detention — triggers assessment only
- Used when person is at immediate risk and unwilling to present voluntarily
- Authorises involuntary admission and treatment in an approved mental health facility
- Made by authorised medical practitioners / psychiatrists
- Reviewed by the Mental Health Tribunal within 21 days
- Patient retains rights — access to advocacy, legal representation, regular review
🚨 Wandering Patient — Alarm & Safety Checklist
Patients with cognitive impairment may be at risk of wandering or absconding — leaving the ward or facility without the knowledge or consent of staff. When this risk is identified, the following safety checklist must be completed and documented. Work through each step below.
📈 Key Dementia Statistics — Australia
Source: Australian Institute of Health and Welfare (AIHW)
- In 2023, dementia was the leading cause of death in Australia — 1 in every 10 deaths
- It is the second leading cause of 'disease burden' after cardiovascular disease
- 6 modifiable risk factors contribute to 43% of all dementia cases
- Australia spent $3.6 billion of the direct health and aged care budget on dementia in 2020–21
- 65% of people living with dementia feel discrimination is common or very common
- 90% of friends and family say their person with dementia has received less respect than others
- Only 54% of Australians feel comfortable around people with dementia
- People with dementia receive less pain relief than others with the same conditions (e.g. fractured bone)
- People born overseas are less likely to be placed in nursing homes — often cared for at home by family
👴 Nursing Considerations
- Use short, simple sentences — one idea at a time
- Allow extra time for processing — do not rush or finish sentences
- Maintain eye contact; approach calmly from the front
- Use the person's preferred name
- Avoid arguing about orientation — use gentle redirection
- Non-verbal communication is powerful — tone, touch, posture
- Consider speech pathology referral if communication is significantly impaired
- Minimise environmental noise and stimulation, especially at night
- Maintain consistent routines and familiar staff where possible
- Ensure adequate lighting — sundowning is worsened by poor light at dusk
- Encourage meaningful activity and gentle mobility
- Address pain, hunger, thirst, and continence needs proactively
- Involve family in care — familiar faces reduce distress
- Identify and treat delirium causes early
- Document capacity assessments — when, by whom, the decision, and rationale
- Note SDM details and their relationship to the patient
- Record all restraint episodes with start/end time, type, and monitoring
- Document behaviour objectively — what you saw, heard, and did
- Record legal orders (SACAT orders, ITO) and their scope in the care plan
- Always document discussions with the treating team and any escalation
- Escalate concerns about capacity to the treating team immediately
- Involve Social Work early — they navigate SACAT and legal document issues
- Refer to Aged Care / Geriatric team for complex dementia presentations
- Refer to CLP (Consultation Liaison Psychiatry) for delirium or mental health concerns
- Contact the Nurse in Charge before applying any form of restraint
- Use your facility's Rapid Response / PACE system if patient deteriorates
Language matters. There has been a significant shift towards Person First Language — placing the person before their diagnosis to recognise they are more than their condition. Some individuals prefer Identity First Language (e.g. "autistic person") — always ask and follow the person's preference.
| ✗ Avoid | ✓ Try instead |
|---|---|
| Suffers with / suffers from dementia | Lives with dementia |
| Wheelchair bound | Full-time wheelchair user / uses a wheelchair |
| Victim of / afflicted by / crippled by | Person who has / person living with |
| Demented / simple / cuckoo | Person with dementia / person with cognitive impairment |
| Special needs / handicapable / differently-abled | Person with a disability / person with support needs |
| Retarded / handicapped / invalid / spastic | Person with an intellectual disability |
| "Inspirational" (for simply living with a disability) | Treat the person as an individual — not a symbol |
Why this matters clinically:
- Stigma makes people less likely to disclose their diagnosis, which means they are less likely to request accommodations — directly impacting their care outcomes
- Offhand comments may be heard by patients, families, or colleagues who have that condition — making them feel unwelcome and unsafe
- Older patients and staff may use outdated terms due to different generational exposure — correct gently and without shaming
- The Social Model of Disability reminds us it is often the environment — not the person — that creates the barrier. Modify the environment wherever possible
