Functional/SocialClinical presentation

Functional decline / inability to cope

A streamlined, differential-led presentation for rapid clinical review.

Clinical snapshot

Twenty-second review

  • New loss of mobility, self-care, or cognition often reflects acute illness superimposed on frailty, medication burden, social stress, or environmental barriers.
  • Sudden decline, delirium, inability to transfer, dehydration, injury, unsafe living conditions, or absent essential support requires escalation.
  • Keep depression or medication effect in the differential; overlapping or concurrent illness remains possible.
  • For functional decline / inability to cope, trends and combinations of findings are more informative than one isolated vital sign.

Serious4 conditions
Occult infectionTime-sensitive high-risk possibility

HPI

Clarify what changed today; acute complaint vs progressive decline; baseline/current mobility and adls.

Signs & symptoms

Acute change, focal finding, pain, fever, or abnormal physiology.

Focused exam

Assess gait and transfers when safe, hydration, skin, cognition, medication access, nutrition, and the living environment; Look for occult infection, injury, pain, or delirium.

Brief pathophysiology

Occult infection may cause functional decline / inability to cope through a time-sensitive process capable of rapid physiological deterioration.

Vital-sign pattern

What the trend may show

Possible pattern

There is no diagnostic vital-sign pattern for a behavioural, functional, or social presentation. Abnormal physiology should be explained and may indicate delirium, toxicity, infection, trauma, or another medical cause.

Temperature (°C)

Screen for medical cause

Fever or hypothermia suggests infection, exposure, or toxicity.

Blood glucose (mmol/L)

Check when indicated

Glucose disturbance can cause altered behaviour or weakness.

Heart rate (bpm)

Explain abnormalities

Tachycardia may reflect distress but should not be dismissed.

Blood pressure (mmHg)

Compare with baseline

Hypotension or severe hypertension warrants medical evaluation.

Front-load in the triage report

  • What changed today?
  • Acute complaint vs progressive decline.
StrokeTime-sensitive high-risk possibility

HPI

Clarify acute complaint vs progressive decline; baseline/current mobility and adls; new weakness/confusion.

Signs & symptoms

Acute change, focal finding, pain, fever, or abnormal physiology.

Focused exam

Look for occult infection, injury, pain, or delirium; Compare baseline ADLs and gait; assess cognition, hydration, skin, nutrition, medication access, pain, infection, and home hazards.

Brief pathophysiology

Stroke may cause functional decline / inability to cope through a time-sensitive process capable of rapid physiological deterioration.

Vital-sign pattern

What the trend may show

Possible pattern

Stroke is a clinical diagnosis supported by time course and neurologic findings. Blood pressure and glucose affect eligibility and mimics; normal vitals do not exclude stroke.

Blood pressure (mmHg)

Often elevated

Hypertension is common in acute stroke; hypotension suggests another cause or poor perfusion.

Blood glucose (mmol/L)

Check every patient

Hypoglycemia can mimic focal deficit; hyperglycemia may accompany stress or diabetes.

Heart rate (bpm)

Assess rate / rhythm

An irregular rhythm may suggest atrial fibrillation but is not required.

Oxygen saturation (SpO₂)

Usually preserved

Hypoxemia requires correction and may indicate aspiration or another process.

Front-load in the triage report

  • Stroke: Acute change, focal finding, pain, fever, or abnormal physiology.
  • Acute complaint vs progressive decline.
  • Baseline/current mobility and ADLs.
FractureTime-sensitive high-risk possibility

HPI

Clarify baseline/current mobility and adls; new weakness/confusion; falls.

Signs & symptoms

Acute change, focal finding, pain, fever, or abnormal physiology.

Focused exam

Look for occult infection, injury, pain, or delirium; Compare baseline ADLs and gait; assess cognition, hydration, skin, nutrition, medication access, pain, infection, and home hazards.

Brief pathophysiology

Fracture may cause functional decline / inability to cope through a time-sensitive process capable of rapid physiological deterioration.

Vital-sign pattern

What the trend may show

Possible pattern

Isolated musculoskeletal injury often leaves central vital signs near baseline. Persistent abnormality should prompt reassessment for hemorrhage, thoracic injury, infection, or a medical cause.

Heart rate (bpm)

May rise with pain

Tachycardia can reflect pain or distress; trend after treatment.

Blood pressure (mmHg)

May rise with pain

Hypotension is not expected in an isolated minor injury.

Respiratory rate (breaths/min)

May rise with pain

Persistent tachypnea suggests more than a minor isolated injury.

Oxygen saturation (SpO₂)

Usually preserved

Desaturation suggests thoracic injury or concurrent disease.

Front-load in the triage report

  • Fracture: Acute change, focal finding, pain, fever, or abnormal physiology.
  • Baseline/current mobility and ADLs.
  • New weakness/confusion.
