The model letter

Miss Ingrid Thorsby Consultant Colorectal Surgeon Colorectal Clinic Calderley General Hospital Wellgate Road Calderley CY4 7RT 26 October 2026 Re: Mr Royston Cawthorne, DOB 11/07/1963 Dear Miss Thorsby, I am writing to refer Mr Cawthorne, a 63-year-old retired electrician, for urgent assessment on the suspected colorectal cancer pathway, following a positive faecal immunochemical test. He presented on 5 October with an eight-week history of looser stools, two to three times a day, with occasional dark red blood mixed in. He also reports tiredness and a 4 kg weight loss over two months. His father was diagnosed with bowel cancer at 70. Examination of his abdomen and rectum was normal. However, his FIT result was 86 µg Hb/g, and blood tests showed iron deficiency anaemia, with a haemoglobin of 112 g/L, an MCV of 76 fL and a ferritin of 6 µg/L. His renal function is normal and coeliac serology was negative. I have started ferrous sulfate 200 mg once daily. He takes ramipril 5 mg and atorvastatin 20 mg daily for hypertension and high cholesterol, and has no known drug allergies. He takes no anticoagulant or antiplatelet medicines. He understands that he may need a colonoscopy but is anxious because of his father's illness. Please note that he is away from 5 to 12 December. I would be grateful if you could see him urgently. Yours sincerely, Doctor Brookfold Surgery

Why this letter works

One point under each OET Writing criterion.

Purpose
The first sentence says what is being asked (urgent assessment), on which pathway, and why (a positive FIT), before any history.
Content
Everything the surgeon needs to triage him is there: the bowel symptoms and how long, weight loss, the family history, the FIT result, the anaemia figures, renal function (it matters for bowel tests), his medicines and allergies, that he takes no blood thinners, and the dates he is away.
Conciseness & Clarity
Details that don't help the surgeon are left out: the allotment, the grandchildren, the gout in 2019 and his alcohol intake. The examination findings are one sentence, because they were normal.
Genre & Style
A formal register between doctors, in full sentences. "Yours sincerely" matches a named reader. Note-form abbreviations (8/52, PR, pt) are written out; standard ones a surgeon expects (FIT, MCV) stay.
Organisation & Layout
One job per paragraph: the request, the history, examination and results, medication, what he knows and when he is away, then the request again in one line.
Language
Past tense for what happened at each visit, present for how he is now. Results are given with their units so nothing is ambiguous.

OET referral letter questions

What letters do doctors write in OET Writing?

Usually a referral letter, for example from a GP to a hospital specialist. It can also be a discharge or transfer letter, or a letter updating another doctor. You write it from case notes in 40 minutes, after 5 minutes of reading time.

How do I start an OET referral letter as a doctor?

Say why you are writing in the first sentence: who the patient is, what you are asking the specialist to do, and how urgently. For example: "I am writing to refer Mr Cawthorne for urgent assessment on the suspected colorectal cancer pathway."

How many words should an OET referral letter be?

Aim for 180 to 200 words in the body of the letter, not counting the address, date or sign-off. Leaving out what the reader doesn't need usually keeps you in that range.

Can I use medical abbreviations in an OET letter?

Write out note-form shorthand (8/52, pt, PR, BD). Standard abbreviations the reader will know, such as FIT or MCV, are fine. If in doubt, write it out: the reader must never have to guess.
