What You Should Be Able to Explain After Reading
- Recognize acute fluctuating cognitive change and hypoactive delirium.
- Understand when a validated delirium screen and urgent medical review are required.
- Adapt rehabilitation to prevent harm while supporting recovery.
Clinical framework
- Delirium is an acute, often fluctuating disturbance of attention and awareness, frequently triggered by illness, medication, pain, dehydration or environmental stress.
- Hypoactive delirium can look like tiredness or low motivation; a sudden reduction in participation may be a clinical warning, not poor effort.
History and risk
- Ask caregivers about baseline cognition and the exact timing of change. Risk rises with age, prior cognitive impairment, hip fracture and severe illness.
- Note sleep disruption, sensory impairment, infection symptoms, constipation, medication changes and reduced intake.
Recognition and screening
- Watch for inattention, altered arousal, fluctuating confusion, hallucinations or unexpected mobility decline.
- NICE recommends the 4AT by a trained practitioner when indicators arise; use CAM-ICU or ICDSC in critical care/recovery settings. The final diagnosis belongs to a qualified clinician.
Differential and urgency
- Consider dementia, depression, stroke, hypoglycemia, hypoxia and medication toxicity; delirium can occur on top of dementia.
- New focal neurological deficits, collapse, severe respiratory compromise or rapidly deteriorating consciousness require immediate medical escalation.
Physiotherapy safety
- Communicate acute change before routine mobilization; check medical stability, lines, falls risk, attention and capacity to follow instructions.
- Use familiar staff, simple single-step cues, hearing/vision aids, supervised transfers and a low-stimulation environment where feasible.
Mobility and prevention
- When medically safe, support short frequent mobility, orientation to place/time, adequate hydration/nutrition through the team, sleep-friendly routines and meaningful engagement.
- A sample approach is several brief supervised sit-to-stand or walking bouts instead of one exhausting session; dose depends on alertness and physiology.
Outcomes and reassessment
- Track assistance needed for transfers, gait safety, attention and daily function; document fluctuations by time of day.
- Review with nursing/medical colleagues frequently and adjust goals until cognition stabilizes.
Common mistakes and summary
- Do not mistake hypoactive delirium for laziness or attempt unsupported walking in a fluctuating patient. Rapid recognition and coordinated care come before ambitious exercise progression.
