Problem: neurology and endocrine referrals stall writers — stroke, TIA, neuropathy, diabetes and thyroid cases each feel like starting over. Answer in brief: cluster them. Neurology letters share a deficit–imaging–request spine; endocrine letters share a control–complication–monitoring spine. Learn two spines instead of twenty cases. This guide teaches cluster writing with a worked stroke referral, and OET Writing for Doctors — Course 2 trains the neurology, diabetes and endocrine clusters across 17 topic sections with mock tests.
The two clusters and their spines
A cluster is a family of cases sharing background facts and finding types. In the neurology and stroke cluster, onset timing, deficits and imaging decide everything — so every letter in the family reports the same three things in the same order. In the diabetes and endocrine cluster, control measures (HbA1c, TFTs, cortisol), complications and monitoring plans recur — so the letter reuses that spine with new numbers. Clustering cuts planning time because half the letter is pre-decided before you read the notes.
Neurology and stroke: deficit, imaging, request
Paragraph order: event and timing (“sudden left-sided weakness at 08:00, resolved by 11:00”); deficits and risks (ABCD2-style factors: age, pressure, clinical features, duration, diabetes — state what applies); imaging and results (CT/MRI findings or “awaited, requested urgently”); precise request (TIA clinic within 24 hours, antiplatelet started, driving advice given). Timing words are doing real work here — “sudden”, “resolved”, “recurrent” each change urgency, so place them early and exactly.

Diabetes and endocrine: control, complications, monitoring
Paragraph order: control snapshot (latest HbA1c/TFT with trend — “risen from 58 to 74 mmol/mol over six months”); complications screen (feet, eyes, renal, cardiac — positive findings first, negatives compressed); current regimen and adherence; monitoring request (referral for optimisation, education, or complication assessment with a named question). Trends persuade more than single values — always pair a number with its direction.
Worked example: suspected TIA referral
Fictional case, newly written: Mrs Adeyemi, 71, sudden slurred speech and right-arm drift at breakfast, fully resolved within two hours; BP 172/96; known hypertension, metformin-controlled diabetes; CT head requested, not yet done; started on aspirin 300 mg; advised not to drive.
Letter shape: “Thank you for seeing Mrs Adeyemi, 71, urgently with a probable TIA this morning.” Background: hypertension, diabetes, no prior events. Today: the event timeline, examination now normal, BP reading, aspirin given, driving advice. Request: “I would appreciate review in the TIA clinic within 24 hours; CT head is awaited and I will forward the report.” Every paragraph answers the neurologist’s next question before it is asked — that is cluster writing.
Four cluster mistakes
- Missing onset timing. A neurology letter without “when” is unactionable. Fix: timing in paragraph 1, always.
- Single values without trends. “HbA1c 74” alone says little. Fix: pair every control number with its direction.
- Imaging vagueness. “Scan done” helps nobody. Fix: modality, finding or “awaited”, and who forwards it.
- Generic requests. “Please see and advise” wastes the cluster. Fix: name the clinic, the timeframe and the question.
FAQs
How urgent is a resolved TIA in OET terms?
Treat it as urgent: guidelines ask for specialist assessment within 24 hours of symptoms. State the timeframe in the request paragraph with the aspirin and driving advice already given.
What if examination is now normal?
Say so plainly — a normal examination after a witnessed deficit is itself the finding. Never invent deficits to fill space; report the timeline and risk factors instead.
What does the course add beyond this article?
Seventeen topic sections across the neurology, diabetes and endocrine clusters plus other specialty referrals, with lessons, examples and 5 complete mock tests for timed practice.
The matching course
OET Writing for Doctors — Course 2 trains doctors in cluster thinking: the neurology and stroke cluster, the diabetes and endocrine cluster and further specialty referrals, across 17 topic sections with 5 complete mock tests. If the two-spine method here clicked, the course turns it into exam-ready habit.
Sources and note
- OET Writing format per the official OET site: oet.com — Writing. Timeframes such as 24-hour TIA assessment reflect widely used clinical guidance; follow local protocols in real practice and current OET format guidance for the exam.
- Course details verified from its public staging page (read-only): 17 topic sections, cluster-based training, 5 mock tests.
- Case and letter lines are newly written and fictional; other valid structures exist.
