Purpose and principles
Use comprehensive geriatric assessment to restore meaningful function after illness or injury through coordinated, goal-based rehabilitation that addresses medical stability, cognition, mood, nutrition, medicines, mobility, environment and caregiver capacity.
Illness, surgery, bed rest and hospital routines rapidly reduce strength, balance and confidence in older adults. A small physiological insult can cross the threshold between independence and dependency when frailty or multimorbidity has narrowed reserve. Rehabilitation should therefore begin alongside diagnosis and treatment, not after every medical issue is resolved. The clinical question is what recovery is possible and valuable, not whether the person is old enough to deserve therapy.
Establish a reliable baseline from the person, family, carers, GP and care records. Record usual walking distance and aid, transfers, stairs, washing, dressing, toileting, cooking, shopping, medicines, cognition, communication and community activity about two weeks before the acute illness. Distinguish long-standing dependence from new loss. A patient who walks 20 metres on the ward may still be far below a baseline of independent outdoor mobility.
Comprehensive geriatric assessment combines medical diagnoses and prognosis with medicines, cognition, delirium, mood, nutrition, continence, sensory function, mobility, falls, skin, social circumstances and patient goals. The multidisciplinary team may include geriatrician, nurse, physiotherapist, occupational therapist, pharmacist, dietitian, speech and language therapist, psychologist and social worker. One coordinator should reconcile recommendations and make ownership visible.
Indications, selection and cautions
New dependency after illness with preserved learning, strength reserve or previous function suggests potential improvement through coordinated practice and medical optimisation.
Symmetrical weakness, poor endurance and postural intolerance after bed rest occur without a new focal neurological deficit.
Inconsistent instruction-following improves with hearing aids, familiar cueing, pain relief or delirium treatment rather than indicating absent potential.
Ward mobility appears acceptable but stairs, low furniture, night toileting or medication tasks exceed capability at the intended destination.
Repeated exhausting sessions without progress toward an outcome valued by the person indicates need to revise intensity, mechanism or goal.
Acute chest pain, hypoxia, hypotension, focal weakness, fever, delirium or severe movement pain requires immediate clinical reassessment before further therapy.
Assessment before treatment
- 01
First-line comprehensive geriatric assessmentFirst stepFirst line - Why
- Integrate diagnoses, medicines, function, cognition, mood, nutrition, continence, falls, sensory status, environment and patient priorities.
- Interpretation and limitations
- The combined problem list and shared goals define the rehabilitation plan and reveal interacting barriers missed by isolated assessments.
- 02
Baseline and current functional profile - Why
- Compare mobility, transfers, ADLs, IADLs, communication and community roles with the stable pre-illness state.
- Interpretation and limitations
- The gap defines recovery targets; longstanding support need should not be mislabelled as acute rehabilitation failure.
- 03
Safe mobility and task assessment - Why
- Observe sit-to-stand, gait, balance, endurance, stairs and relevant daily tasks using the usual aid where possible.
- Interpretation and limitations
- Performance identifies assistance, equipment and exercise needs, but fatigue and day-to-day variation require repeated observation.
- 04
Medical barrier screen - Why
- Assess pain, orthostatic pressure, oxygenation, infection, anaemia, heart failure, neurological change and medicine effects according to symptoms.
- Interpretation and limitations
- Treatable physiology can unlock rehabilitation; broad tests without a clinical hypothesis add burden and delay.
Treatment approach
01Initial rehabilitation pathwayStabilise barriers and define a meaningful baselineFirst stepAn older adult loses function during illness, injury, surgery or hospital admission.+
- 1Establish pre-illness function and the person's priorities, then complete multidisciplinary medical, cognitive, nutritional, mobility and social assessment.
- 2Treat pain, delirium, postural symptoms, infection, hypoxia, medicine burden and missing sensory aids while beginning safe activity early.
- 3Agree measurable task-based goals, intensity, responsible professionals and a review date in one shared plan.
02Progressive practiceBuild strength and independence through relevant tasksThe person is medically stable enough for repeated active rehabilitation.+
- 1Deliver progressive strength, balance, endurance and functional practice matched to the intended activities and monitor physiological response.
Complications, monitoring and follow-up
- Track patient-defined activities and required assistance rather than documenting only minutes of therapy.
- Repeat mobility and endurance under ordinary fatigue and time-of-day conditions before discharge decisions.
- Review pain, postural symptoms, oxygenation, delirium and medicine adverse effects when participation changes.
- Monitor weight, intake, swallowing and bowel function because nutritional and gastrointestinal problems limit recovery.
- Confirm equipment delivery, fit and actual use and retrain when the person or environment changes.
- Ask carers privately about skill, physical strain and willingness before relying on their assistance.
- Reassess goals after acute deterioration, plateau, destination change or a shift toward end-of-life priorities.
Special situations
Baseline is not age matched
Recovery should be compared with the individual's own prior life rather than a generic expectation for people of similar age.
Practice is the active ingredient
Assessment identifies deficits, while sufficiently repeated and progressive task performance produces functional adaptation.
Dementia changes the method
Consistent cueing and procedural repetition can support meaningful gains even when explicit new learning is limited.
Ward success may not travel
Level floors, raised beds and nearby staff can conceal difficulty with the actual home, stairs and night routine.
Carer ability is clinical data
A transfer plan is ineffective when the person expected to assist has pain, fear or has not freely accepted the task.
Comfort can be rehabilitative
Maintaining a painless transfer or enough stamina for family conversation can be an appropriate functional outcome near death.
Common pitfalls
- 01
Excluding a person from rehabilitation solely because of dementia, frailty or care-home residence.
- 02
Starting therapy without establishing the person's own baseline and valued activity.
- 03
Calling reduced participation unmotivated before checking pain, delirium, depression and communication.
- 04
Using passive movement as the entire response to strength and balance loss.
- 05
Creating separate discipline goals that compete for the person's limited energy.
- 06
Measuring success only with a scale while toileting and home access remain impossible.
- 07
Assuming one good morning session predicts independent function throughout the day.
- 08
Prescribing equipment without checking delivery, fit and ability to use it.
- 09
Assuming family will provide transfers and supervision without private assessment.
- 10
Describing a shift toward maintenance or comfort as giving up.
