This is an iatroX educational summary of named Australia sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. Apply current TGA product information, PBS restrictions, state or territory law, local referral criteria, formulary and antimicrobial policy. A national recommendation does not create uniform service access.

Scope

Suspect delirium with an acute fluctuating change in attention, awareness or cognition, including quiet hypoactive presentations that are easily missed. Establish baseline cognition and function from family or carers and use a validated delirium assessment in the relevant setting. This summary is limited to the population, decisions and escalation boundaries stated in the named source.

The Bottom Line

  • Suspect delirium with an acute fluctuating change in attention, awareness or cognition, including quiet hypoactive presentations that are easily missed.
  • Establish baseline cognition and function from family or carers and use a validated delirium assessment in the relevant setting.
  • Use family presence, clocks, daylight, hearing aids and glasses to reduce disorientation and distress.
  • Search promptly for multiple precipitants such as infection, pain, retention, constipation, hypoxia, dehydration, medicine toxicity and withdrawal.

Practical clinical workflow

1

Topic-specific assessment action

Suspect delirium with an acute fluctuating change in attention, awareness or cognition, including quiet hypoactive presentations that are easily missed.
2

Topic-specific diagnostic action

Search promptly for multiple precipitants such as infection, pain, retention, constipation, hypoxia, dehydration, medicine toxicity and withdrawal.
3

Topic-specific management action

Provide orientation, hydration, sensory aids, sleep support, mobility and family involvement while treating causes; avoid restraint and routine antipsychotics.
4

Topic-specific follow-through

Review anticholinergic, sedative and opioid burden and treat withdrawal risks carefully rather than stopping every medicine abruptly.

Safety boundaries and escalation

  • Urgently escalate physiological instability, focal neurology, reduced consciousness, severe agitation threatening safety or a cause requiring immediate intervention.
  • Document delirium at discharge because cognition and function may remain impaired and future vulnerability is increased.

Implementation

The named source is national or binational guidance used in Australia, but referral access, public-health directions, formularies and funded services can still differ by state, territory and health service. Check current TGA product information for medicines. Offer culturally safe care and use the NACCHO鈥揜ACGP National Guide where Aboriginal and Torres Strait Islander preventive or chronic-care recommendations differ.
