Using NICE guidelines effectively for MRCEM SBA

You have eight weeks until your MRCEM SBA, you have just opened the NICE guidance index for the umpteenth time, and you are now staring at well over a thousand published guidelines. The instinct is to start at A, work through to Z, and burn out somewhere around Bedwetting in children. Don’t. The SBA is a sample, not a census, and your revision should be too. See also our guide to revising RCEM guidelines as the primary source. See also our guide to the MRCEM Intermediate SBA pass percentage.

TL;DR: Do not try to read NICE in full. The MRCEM Intermediate SBA is blueprinted to the RCEM 2021 curriculum and samples a predictable set of common, high-risk ED presentations. Pick the 12 to 15 NICE guidelines that map directly to those presentations (sepsis, AKI, head injury, chest pain, anaphylaxis, asthma, AF, stroke, paediatric fever, DKA, DVT/PE, paracetamol overdose, self-harm, and one or two recently updated ones), read each in 30 to 45 minutes, summarise to a single A4 sheet, and drill the decision points with timed SBAs. Revise the algorithm and the thresholds, not the paragraphs.

Why does NICE feel so overwhelming when you start revising for the SBA?

Because the catalogue is not built for an exam. NICE publishes hundreds of guidelines for English NHS practice, ranging from acute ED-relevant pathways (sepsis, head injury, anaphylaxis) to chronic primary-care territory (heart failure follow-up, type 2 diabetes monitoring, bedwetting). The MRCEM Intermediate SBA only cares about a thin slice: things that walk through an ED door undifferentiated and need a safe early decision.

The exam is explicitly mapped to the RCEM Emergency Medicine Curriculum 2021 and tests across the Year 1 to 3 Specialty Learning Outcomes (SLOs). The 180 questions are roughly weighted: SLO1 (complex stable patient) gets the lion’s share, then SLO3 (resuscitation and organ failure), then SLO4 (injured patient), SLO5 (paediatrics), SLO6 (procedures), and SLO7 (ethical/challenging). That weighting tells you which NICE guidelines actually earn marks and which are noise for this exam.

What does the SBA actually test from a NICE guideline?

Almost never the whole document. Stem after stem, you will see the same pattern:

• Recognition — does this patient meet the high-risk criteria? (suspected sepsis, head-injury CT criteria, anaphylaxis triad)
• First-line investigation — what do you order in the next 15 minutes? (troponin pathway, D-dimer with Wells, lactate, paracetamol level at 4 hours)
• First-line treatment and thresholds — what dose, what target, what time window? (IM adrenaline 500 micrograms, thrombolysis window, glucose target in DKA)
• Disposition and safety-netting — admit, observe, refer, or safe to discharge with what advice?

If your revision sheet captures those four things for each guideline, you have 80% of the exam-relevant content. The rest — research recommendations, cost-effectiveness, equality considerations — will not appear in a stem.

How should I pick which NICE guidelines to actually study?

Work backwards from the exam blueprint, not forwards from the NICE index. Three filters:

1. Does this present to the ED commonly? If a guideline covers a condition the average ED sees daily or weekly, it is on the syllabus. If it covers a clinic referral pathway, it almost certainly isn’t.
2. Does it carry a clear “what to do in the first hour” pathway? SBA questions love time-critical decisions. Guidelines with explicit algorithms (sepsis, ACS, stroke, anaphylaxis, head injury) are heavy hitters.
3. Has it been updated recently? Examiners are drawn to changes. NG258 (anaphylaxis, May 2026), NG245 (asthma, 2024) and NG232 (head injury, 2023) are recent enough that older textbooks will mislead you.

Apply those filters and you end up with a manageable list of around a dozen.

Which NICE guidelines should be on the shortlist for MRCEM SBA in 2026?

This is the working list I’d put in front of any SBA candidate today. Tier 1 are the ones you cannot afford to be vague on; Tier 2 are predictable enough to be worth a dedicated A4 each; Tier 3 are worth a half-page summary and a few SBAs.

*Paracetamol overdose is governed by the MHRA nomogram and BNF, not a NICE guideline, but it appears so reliably on the SBA that it earns Tier 1 status by exam frequency. The same applies to RCEM’s own best-practice guidelines (e.g. major haemorrhage, sedation in adults), which sit alongside NICE in any sensible revision plan.

How long should I spend on each guideline?

Aim for one Tier 1 guideline per study session of around 60 to 90 minutes. The session looks like this: See also our guide to how to use RCEM Learning sessions for revision.

• 0 to 10 minutes — open the NICE guideline’s “Recommendations” page and skim only the headings and the algorithms (most have a downloadable visual summary; print it).
• 10 to 30 minutes — read the recognition section and the first-line management section in detail. Highlight numbers (thresholds, doses, time windows) ruthlessly.
• 30 to 45 minutes — write a one-page summary of your own. Headings: Recognise, Investigate, Treat, Dispose, Pitfalls.
• 45 to 90 minutes — do 15 to 25 SBAs from your question bank tagged to that topic, reviewing every wrong and every guessed-right answer against your sheet. Update the sheet with anything you got wrong.

Tier 2 guidelines deserve maybe half that time. Tier 3 — a 20-minute skim and a handful of SBAs.

What about RCEM-specific resources and the curriculum?

NICE is not the whole story. RCEM publishes its own Best Practice Guidelines (BPGs) on topics where NICE is silent or where the College wants ED-specific guidance — major haemorrhage, procedural sedation, traumatic cardiac arrest, mental health in ED. RCEMLearning hosts the FOAMed content most aligned to how the SBA is written, and RCEM’s sample question pack is the closest thing to the real paper’s tone you will see for free. Always pair a NICE deep-dive with a quick check of the corresponding RCEM BPG; where they disagree, the SBA usually rewards the answer that aligns with current NICE plus RCEM nuance for the ED setting.

How do I revise the numbers without trying to memorise paragraphs?

The SBA punishes paragraph-memorisation. It rewards three things:

1. Algorithm visualisation. If you can sketch the sepsis screening tool from memory in under 90 seconds — moderate-risk and high-risk criteria, lactate cut-offs, antibiotic timing — you have the marks. Most NICE guidelines have an official visual summary PDF; download it, redraw it, repeat.
2. Threshold flashcards. Anki or paper, your choice. Each card is one number with its context. “Adult IM adrenaline dose in anaphylaxis” → “500 micrograms (1:1000), repeat after 5 minutes if no response”. Aim for around 200 to 300 cards across all the Tier 1 guidelines.
3. Decision-point drills. For each guideline, write yourself five “what would you do next?” prompts. “GCS 13 head injury, anticoagulated, no other features — CT or not?” “Asthma adult, PEFR 35%, SpO2 91%, HR 130 — life-threatening or acute severe?” If you can answer these in two seconds, you will answer the SBA stem in twenty.

Are there pitfalls candidates keep falling into with NICE on the SBA?

Four traps, all reported repeatedly by recent candidates on r/doctorsUK and in pass-experience writeups:

• Memorising the wrong vintage. Anaphylaxis is the live example right now: NG258 replaced CG134 in May 2026, and textbooks printed before then carry the old wording. Always check the “last updated” date on the NICE page before trusting a number.
• Confusing NICE with international guidance. Surviving Sepsis Campaign, AHA/ACC, ESC, ERC — these all exist, sometimes disagree with NICE, and almost never give you the right SBA answer. The MRCEM is a UK exam: when in doubt, NICE wins.
• Ignoring paediatrics. SLO5 is ~25 of the 180 questions. NG143 (fever under 5s), paediatric sepsis criteria in NG51, paediatric head injury rules in NG232 and paediatric asthma in NG245 all matter — and they have different thresholds from adult equivalents.
• Over-revising rare conditions. Candidates burn time on zebras (porphyria, MEN syndromes, exotic toxidromes) and run out of capacity for the bread-and-butter NICE pathways that supply 60% of the paper.

How do I integrate NICE revision into a wider SBA study plan?

Pick a 10 to 12 week run-up. A rough split that works for most candidates:

• Weeks 1 to 4 — work through the Tier 1 NICE guidelines, one per session, three to four sessions a week. Build your A4 summary stack.
• Weeks 4 to 6 — Tier 2 guidelines + RCEM BPGs (major haemorrhage, procedural sedation, mental health, end of life). Continue SBAs daily.
• Weeks 6 to 9 — full-length timed mocks. 180 questions across two two-hour blocks with the one-hour break, mimicking the real exam. After each mock, re-read the summary sheets for every wrong answer’s topic.
• Weeks 9 to 10 — final pass through your stack of A4 sheets only. No new content. Sleep, hydrate, sit the exam.

What’s the single highest-yield change I can make to my revision tomorrow?

Stop reading guidelines linearly. Open your question bank, do 20 SBAs, and for every one you got wrong or guessed, look up the relevant NICE guideline and read only the section that the question tested. Repeat daily. You’ll cover the high-yield content in the order the exam cares about, which is much faster than starting at NG1.

Frequently asked questions

Do I need to know NICE guidelines by their NG number?

No. Examiners want the clinical content, not the reference. Knowing “NG51” is a flex; knowing the high-risk criteria within it is a mark.

Should I read the full NICE document or just the summary?

For Tier 1 guidelines, read the full “Recommendations” page once, then live off your own one-page summary thereafter. The full evidence reviews are for clinicians implementing the guideline, not for sitting an SBA.

How recent does a NICE guideline have to be to risk being on the exam?

Anything updated in the last 18 months is fair game. The asthma joint guideline (NG245) and the new anaphylaxis guideline (NG258) are the obvious candidates for the 2026 diet.

What if NICE and the BNF disagree?

For dosing, BNF wins (it’s the regulatory source). For pathway and decision logic, NICE wins. SBA questions are almost always about pathway, so default to NICE unless the stem is specifically a dose.

Do I need to learn NICE Quality Standards as well as guidelines?

No. Quality Standards (QS series) are commissioning tools, not clinical pathways. Stick to NG and CG documents.

How much paediatrics-specific NICE content do I need?

Enough to cover NG143 (fever under 5s), paediatric sepsis criteria, head injury rules for children, paediatric asthma in NG245, paediatric BLS/ALS principles, and safeguarding triggers. That’s around 25 of 180 marks — not optional.

Is there a downloadable list of “the NICE guidelines on the MRCEM SBA”?

No official one — RCEM does not publish it. The table above is a consensus derived from the curriculum, recent candidate experience and the actual frequency of NICE-referenced stems in commercial question banks. Treat it as a strong shortlist, not a guarantee.

What about overdoses, toxicology and TOXBASE?

TOXBASE is not NICE, but paracetamol, opioid, tricyclic, beta-blocker, calcium-channel blocker and digoxin overdoses appear regularly. Have a one-pager for each common toxidrome and know the antidotes by dose.

How many SBAs should I do total before the exam?

Most successful candidates report 2,000 to 4,000 questions across their preparation, with at least one full cycle done under timed conditions in the final fortnight.

Do I need to memorise CHA₂DS₂-VASc, Wells, GCS, NEWS2?

Yes, all of them. Plus PESI for PE risk, ABCD2 has been retired by NICE but the components are still useful, and the Glasgow-Blatchford score for upper GI bleeding. Score systems are easy marks if memorised cold.

Is RCEMLearning enough on its own?

Not quite. RCEMLearning is excellent for free clinical content and FOAMed-style writeups, but a commercial SBA question bank (FRCEMtutor, MRCEMExamPrep, MRCEMSuccess, Ultimate MRCEM) gives you the volume of mock questions you need to build pattern recognition.

What’s the pass mark and how negatively-marked is the SBA?

There is no negative marking — one mark per correct answer, zero for wrong. The pass mark is set per diet using the Angoff method plus one standard error of measurement; in practice candidates report around 65% of marks as a working target.
