Editorial standards
How we write, review, and maintain our medical content.
Every revision note, question explanation, and study guide on PLABRevisions is written and reviewed by UK doctors against the current National Institute for Health and Care Excellence (NICE) guidelines, the British National Formulary (BNF), Clinical Knowledge Summaries (CKS), the Scottish Intercollegiate Guidelines Network (SIGN), and the General Medical Council's Good Medical Practice. We document the process here so candidates, search engines, and AI search assistants can understand exactly how we keep medical content accurate.
Our source hierarchy
When a fact differs across sources, we follow this strict order of authority for UK clinical practice:
Tier 1 — UK regulatory & guideline bodies
General Medical Council (GMC), NICE, BNF, CKS, SIGN, NHS England / NHS Scotland / NHS Wales / NHS Northern Ireland, and the Royal Colleges. Where a UK guideline exists, it is the primary citation regardless of what international literature says.
Tier 2 — Royal College curricula & speciality bodies
Royal College of Physicians, Royal College of Surgeons, Royal College of General Practitioners, Royal College of Psychiatrists, Royal College of Paediatrics and Child Health, Royal College of Obstetricians and Gynaecologists. Used where Tier 1 is silent.
Tier 3 — Peer-reviewed evidence
Cochrane reviews, BMJ Best Practice, UpToDate (cross- checked), and primary trial literature. Used to provide context but never to override a current UK guideline.
How often we review and update
- Within 14 days of a NICE / BNF / CKS / SIGN release. Notes and question explanations affected by a guideline change are flagged and rewritten by the medical content team. Where dose, threshold, or first-line management has changed, the previous answer is retired or rewritten.
- Quarterly sweep. Every 90 days the team performs a full audit of the top-traffic clinical topics (cardiology, respiratory, endocrine, ethics) against current guidance.
- After every UK Medical Licensing Assessment sitting. Candidate-shared recall posts are reviewed for systematic pattern shifts (e.g. increased emphasis on a specific presentation), and the question bank is rebalanced.
- User-flagged review. Every question carries a "Flag this question" link. Flagged questions are triaged within 5 working days and rewritten or retired where appropriate.
Who writes and reviews our content
Content is produced by a team of UK-trained doctors and medical educators with current clinical practice in the NHS. Each piece carries a named reviewer team in its byline (e.g. "MedRevisions Lead Clinical Educator", "Guidelines Working Group"), and every clinical claim links to a primary source from the hierarchy above.
We do not publish AI-generated medical content unchanged. AI tools are used to draft first passes, but every fact is verified against the source hierarchy by a clinician before publication. AI-assisted content is clearly labelled where used.
Where a candidate-shared review or testimonial is used, it is verified — we hold the original timestamped source (Trustpilot, Facebook group, email, Google review) on file and can produce it on request.
Corrections & feedback
If you believe a question, explanation, or note contains an inaccuracy, please email support@medrevisions.com with the page URL or question ID. We acknowledge receipt within one working day and triage clinical corrections within five.
Material corrections that change an answer or recommendation are reflected with a "Last updated" stamp on the page and an entry in our public changelog (linked from every news article).
