Functional/SocialClinical presentation

Housing insecurity / social crisis

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

Clinical snapshot

Twenty-second review

  • Housing insecurity increases exposure, interrupted medications, chronic disease burden, injury, infection, malnutrition, and barriers to follow-up; the presenting concern may be medical, social, or both.
  • Environmental exposure, unsafe discharge, severe infection, injury, withdrawal, suicidal risk, or inability to access essential medication requires escalation.
  • Keep perceived social-only request in the differential; overlapping or concurrent illness remains possible.
  • For housing insecurity / social crisis, trends and combinations of findings are more informative than one isolated vital sign.
Differentials

Compare the clinical patterns

The repeated material is grouped inside each possibility. Open only the condition you need.

Serious4 conditions
SepsisTime-sensitive high-risk possibility

HPI

Clarify immediate medical complaint; exposure, nutrition or medication needs; safety and vulnerability.

Signs & symptoms

Systemic or safety findings require urgent care.

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

Sepsis may cause housing insecurity / social crisis through a time-sensitive process capable of rapid physiological deterioration.

Vital-sign pattern

What the trend may show

Possible pattern

No single vital sign diagnoses sepsis. New tachypnea, abnormal temperature, tachycardia, or falling pressure—especially with altered mentation or poor perfusion—supports organ dysfunction and urgency.

Respiratory rate (breaths/min)

May rise early

Tachypnea is included in NEWS2 and can precede overt hypotension.

Temperature (°C)

High or low

Absence of fever does not exclude sepsis; hypothermia is concerning.

Heart rate (bpm)

Often rises

Tachycardia is common but may be blunted by age or medication.

Blood pressure (mmHg)

May fall

Relative hypotension and trend matter; profound hypotension can be late.

Exposure injuryTime-sensitive high-risk possibility

HPI

Clarify exposure, nutrition or medication needs; safety and vulnerability; mobility and cognition.

Signs & symptoms

Systemic or safety findings require urgent care.

Focused exam

Look for occult infection, injury, pain, or delirium; Assess the stated priority, temperature exposure, wounds, feet, hydration, nutrition, respiratory illness, medications, substance use, safety, and available supports.

Brief pathophysiology

Exposure injury may cause housing insecurity / social crisis 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.

TraumaTime-sensitive high-risk possibility

HPI

Clarify safety and vulnerability; mobility and cognition; available shelter or outreach supports.

Systemic or safety findings require urgent care.

Focused exam

Look for occult infection, injury, pain, or delirium; Assess the stated priority, temperature exposure, wounds, feet, hydration, nutrition, respiratory illness, medications, substance use, safety, and available supports.

Signs & symptoms

Systemic or safety findings require urgent care.

Focused exam

Look for occult infection, injury, pain, or delirium; Assess the stated priority, temperature exposure, wounds, feet, hydration, nutrition, respiratory illness, medications, substance use, safety, and available supports.

Brief pathophysiology

Acute mental-health crisis may cause housing insecurity / social crisis through a time-sensitive process capable of rapid physiological deterioration.

Focused exam
