MRCEM
Your foundation in emergency medicine — structured guidance for every component of the RCEM membership pathway.
The MRCEM Pathway
The Membership of the Royal College of Emergency Medicine (MRCEM) is the benchmark postgraduate qualification for emergency medicine trainees in the UK. Achieving MRCEM demonstrates competence across the breadth of acute and emergency presentations, underpinned by the RCEM 2021 curriculum.
The exam pathway comprises three sequential components: the MRCEM Primary (SBA), the MRCEM Intermediate (SBA), and the MRCEM OSCE. Candidates must pass each component before progressing to the next. The entire pathway typically takes 12–24 months to complete, depending on sitting frequency and preparation intensity.
MRCEM is a prerequisite for progression to higher specialty training (ST4+) and forms the foundation for the Fellowship (FRCEM) examination. The pass mark is set using Angoff standard-setting methodology, ensuring consistent standards across sittings.
Key Facts
Three Components of MRCEM
MRCEM Primary (SBA)
The first hurdle — a single best answer paper testing basic sciences applied to emergency medicine.
What to expect
- Questions test applied basic science — not pure recall
- Clinical vignettes mapped to common ED presentations
- Negative marking does not apply — answer every question
- Pharmacology and anatomy are consistently high-yield domains
MRCEM Intermediate (SBA)
Applied knowledge test examining clinical decision-making across the full emergency medicine curriculum.
What to expect
- Scenario-based questions reflecting real ED practice
- Heavy emphasis on acute management and disposition decisions
- NICE guidelines and RCEM best practice guidelines are tested directly
- Paediatric emergencies form a significant proportion of questions
MRCEM OSCE
Objective Structured Clinical Examination assessing clinical and communication competence across 16 stations.
Station types
- Clinical assessment: focused history and examination
- Communication: breaking bad news, consent, safety-netting
- Procedural skills: suturing, joint aspiration, nerve blocks (simulated)
- Data interpretation: ECG, ABG, imaging review
- Resuscitation: structured approach to the deteriorating patient

High-Yield Clinical Domains
Resuscitation
Adult and paediatric ALS per Resuscitation Council UK 2021. Cardiac arrest management, peri-arrest arrhythmias, post-ROSC care, and team leadership in the resuscitation room.
Major ED Presentations
Chest pain, breathlessness, abdominal pain, headache, syncope, and the undifferentiated unwell patient. Systematic approach to differential diagnosis and risk stratification using validated scores.
Procedures & Skills
Practical competence in core emergency procedures: chest drain insertion, joint aspiration, wound closure, regional anaesthesia, procedural sedation, and emergency airway management.
Guidelines & Evidence
NICE clinical guidelines, RCEM best practice guidelines, BTS guidelines, and Resuscitation Council UK algorithms. Understanding when and how to apply evidence-based protocols in time-pressured settings.
How to Prepare Effectively
Question Banks
Consistent, daily question practice is the single most effective strategy for the SBA components. Aim for 50–100 questions per day in the final 8 weeks before each sitting.
- PassMedicine MRCEM: Comprehensive bank mapped to the RCEM curriculum with detailed explanations
- BMJ OnExamination: High-quality questions with evidence-based rationales
- RCEM Learning: Free official resources including sample questions and learning modules
- Track your performance by domain — focus revision on consistently weak areas
- Simulate exam conditions: timed blocks of 30 questions without interruption
OSCE Frameworks
The OSCE tests clinical competence under time pressure. Structured frameworks prevent disorganisation and ensure you cover mark-earning domains consistently.
- History stations: Use a systematic framework — presenting complaint, HPC, systems review, PMH/DH/SH/FH, ICE (ideas, concerns, expectations)
- Examination stations: Inspect, palpate, percuss, auscultate — always offer to complete the examination
- Communication stations: Calgary-Cambridge model — establish rapport, gather information, explain, plan
- Procedural stations: WHO checklist approach — indication, consent, equipment, technique, aftercare
- Practise with peers and record yourself — review for filler words, missed domains, and time management
Revision Timeline
A structured timeline prevents last-minute cramming and ensures comprehensive curriculum coverage.
6 months before
Begin content review. Read through core textbooks (Tintinalli, Rosen). Start question bank — 20–30 questions daily. Identify weak domains early.
3 months before
Increase question volume to 50+ daily. Begin OSCE practice sessions weekly. Review NICE guidelines systematically. Start timed mock exams.
6 weeks before
Peak intensity. 80–100 questions daily. OSCE practice 2–3 times per week. Focus on weak areas identified from question bank analytics. Full mock OSCE circuits.
Final 2 weeks
Consolidation. Review marked/flagged questions. Revise high-yield summaries. One full timed mock exam under real conditions. Rest adequately before the exam.
Essential Clinical Frameworks
Cardiac Arrest — ALS Algorithm
Shockable rhythms (VF/pVT): Defibrillate → 2 min CPR → reassess. Adrenaline 1mg IV after 3rd shock, then every 3–5 min. Amiodarone 300mg after 3rd shock, 150mg after 5th.
Non-shockable (PEA/Asystole): Adrenaline 1mg IV immediately, then every 3–5 min. Continue CPR cycles. Identify and treat reversible causes.
4Hs: Hypoxia, Hypovolaemia, Hypothermia, Hypo/Hyperkalaemia. 4Ts: Tension pneumothorax, Tamponade, Toxins, Thrombosis.
Sepsis — NEWS2 and Sepsis 6
Recognition: NEWS2 score ≥5 (or 3 in one parameter) triggers sepsis screening. Look for: infection source + organ dysfunction.
Sepsis 6 (within 1 hour):
Give 3: IV antibiotics, IV fluid challenge (500ml crystalloid), high-flow O₂ (target SpO₂ ≥94%).
Take 3: Blood cultures, lactate, urine output monitoring.
Red flags: Lactate >4 mmol/L, systolic BP <90, no response to fluid bolus → escalate to critical care.
Acute Coronary Syndromes
STEMI: 12-lead ECG within 10 minutes. If PCI available within 120 min → primary PCI. If not → thrombolysis within 30 min of diagnosis.
NSTEMI: Risk stratify with GRACE score. Dual antiplatelet therapy (aspirin + ticagrelor per NICE TA236). Fondaparinux (unless high bleeding risk). Angiography within 72 hours for intermediate-high risk.
High-sensitivity troponin: Use 0/3h or 0/1h rule-out pathways per local protocol and ESC guidelines.
Major Trauma — <C>ABCDE
<C> Catastrophic haemorrhage: Direct pressure, tourniquets, haemostatic agents.
A — Airway: Jaw thrust (trauma), suction, adjuncts. Assume C-spine injury until cleared.
B — Breathing: Tension pneumothorax (needle/finger thoracostomy), massive haemothorax (chest drain), flail chest.
C — Circulation: 2 large-bore IV, crystalloid, activate major haemorrhage protocol (1:1:1 ratio). Pelvic binder if suspected fracture.
D — Disability: GCS, pupils, glucose, lateralising signs.
E — Exposure: Full exposure, log roll, temperature management.
Common Mistakes & How to Avoid Them
Running out of time in SBA papers
With 180 questions in 3 hours, you have exactly 1 minute per question. If a question takes more than 90 seconds, flag it and move on. Return to flagged questions at the end. Never leave blank answers.
Ignoring the OSCE reading time
The 1-minute reading time is critical. Use it to identify: the task (history/examination/procedure), the marking domains, and your opening line. Candidates who skip this step lose structure immediately.
Studying breadth without depth
Covering every topic superficially is less effective than mastering high-yield domains. Resuscitation, trauma, and paediatrics appear in every sitting. Know these cold.
Poor guideline recall under pressure
NICE and RCEM guidelines are tested directly. Learn the guideline numbers and key thresholds (e.g., NEWS2 escalation triggers, CT head criteria). Flashcards and spaced repetition are highly effective.
Neglecting communication skills
Communication stations carry equal marks to clinical stations. Practise breaking bad news, gaining consent, and safety-netting. Use structured models (SPIKES, Calgary-Cambridge) consistently.
Not practising under exam conditions
Timed mocks reveal weaknesses that untimed study does not. Complete at least two full timed SBA papers and one complete OSCE circuit before the real exam.
