The Emergency Department Mindset

The ED is fundamentally different from ward medicine. You are managing undifferentiated presentations, uncertainty, and multiple patients simultaneously. The key skill is safe disposition — getting the right patient to the right place at the right time.

Triage and Prioritisation

  • Know your triage system: Manchester Triage System (UK/Ireland/ANZ), ESI (USA/Canada), or local equivalent
  • Triage category 1 (immediate/resus): airway compromise, cardiac arrest, haemorrhage
  • Triage category 2 (urgent): chest pain, stroke, severe pain, sepsis
  • When you have multiple patients: always see the sickest first
  • If you don't know who is sickest — ask the charge nurse. They know.

The Approach to Any ED Patient

  1. Eyeball test first: Does this patient look sick? Pale, diaphoretic, tachypnoeic, altered — these patients jump the queue
  2. Primary survey (ABCDE): Airway, Breathing, Circulation, Disability (GCS), Exposure
  3. Focused history: HPC, relevant PMH, medications, allergies — not a full clerking
  4. Targeted examination: Relevant to the presenting complaint
  5. Investigations: Order what will change management — not everything
  6. Disposition decision: Home, admit, observe, refer to another specialty

High-Yield ED Presentations to Know

  • Chest pain: ACS, PE, aortic dissection, tension pneumothorax, oesophageal rupture — the dangerous five
  • Headache: SAH until proven otherwise if sudden-onset thunderclap — immediate CT head
  • Sepsis: Identify early; Sepsis Six / bundle initiation; blood cultures before antibiotics
  • Stroke: FAST positive — immediate CT, thrombolysis eligibility assessment, time is brain
  • Trauma: ATLS primary/secondary survey; activate major haemorrhage protocol early if indicated
  • Paediatric fever: Meningitis, sepsis, UTI — age-specific safety netting is essential

Night Shifts in the ED

  • Prepare: sleep before your first night; blackout blinds and no commitments the next day
  • Eat properly during the shift — your decision-making degrades when hungry
  • Fatigue increases cognitive errors — if unsure, ask. Nobody expects perfection at 4am, but they do expect you to escalate
  • Handover carefully — the ED at 7am handover is the highest-risk moment for missed diagnosis

Getting the Most from Your ED Rotation

  • Volunteer for resuscitation room exposure early
  • Ask to attend trauma calls and cardiac arrest teams
  • Practice procedural skills: IV cannulation, ABGs, urinary catheterisation, wound closure
  • Log your cases and any procedures in your e-portfolio from day one
