Mastering the OET medicine referral letter COPD pulmonologist task is a pivotal step for international medical graduates aiming for professional registration with the GMC – General Medical Council UK or other international healthcare boards. This specific clinical scenario—referring a patient with worsening Chronic Obstructive Pulmonary Disease (COPD) to a specialist—is a frequent theme in the OET Writing sub-test because it requires the candidate to demonstrate high-level clinical reasoning and precise communication. In this comprehensive guide, we will analyze a Grade B model answer, examine the marking criteria in depth, and provide practical tools to help you succeed in your 45-minute writing challenge.

While this post focuses on a referral letter for a respiratory condition, it is important to remember that the OET Writing sub-test can also involve other formats. For instance, you might be required to write a OET Medicine Writing: Discharge Summary – Hip Fracture Sample, which requires a different organizational approach focused on post-operative care and rehabilitation. Regardless of the letter type, the core assessment remains the same: can you convey the necessary medical information to a colleague clearly and professionally?

Re: Mr. Arthur Miller, DOB: 12/05/1957

Dear Dr. Jenkins,

I am writing to urgently refer Mr. Miller, a 68-year-old retired construction worker, whose clinical presentation and recent investigations strongly suggest moderate-to-severe Chronic Obstructive Pulmonary Disease (COPD). He requires specialist assessment and optimization of his management plan.

Mr. Miller first presented in February with a persistent cough and mild exertional dyspnoea. Despite initial management with PRN Salbutamol, he returned today reporting a significant decline. He now experiences shortness of breath after walking only 50 meters, accompanied by a productive cough and a 4kg weight loss over two months. Notably, he has a 40-year smoking history.

On examination, Mr. Miller appeared lean with signs of accessory muscle use. His oxygen saturation was 91% on room air. Chest auscultation revealed decreased breath sounds and diffuse wheezing. Recent spirometry confirmed airflow obstruction with a post-bronchodilator FEV1 of 48% and an FEV1/FVC ratio of 0.58. Furthermore, his chest X-ray showed hyperinflation and flattened diaphragms.

I have commenced Mr. Miller on Tiotropium 18mcg daily. I would appreciate your expert evaluation regarding his suitability for long-term oxygen therapy and pulmonary rehabilitation.

Yours sincerely,

Doctor

Examiner Analysis

To achieve a Grade B or higher, candidates must meet specific requirements across six criteria. Below is a breakdown of how the model letter performs against these standards. In OET Writing, a Grade B typically requires a 2 out of 3 in Purpose and at least 5 out of 7 in the remaining categories.

Purpose

The purpose of this letter is immediately apparent in the opening paragraph. The candidate uses the phrase “I am writing to urgently refer” and clearly states the suspected diagnosis (COPD). By mentioning the need for “specialist assessment and optimization,” the reader knows exactly why they are receiving this patient before they even finish the first paragraph. This directness is essential for a high score in this criterion.

Content

All relevant information from the case notes has been included without including unnecessary clutter. The letter focuses on the “40-year smoking history,” the “FEV1 of 48%,” and the “4kg weight loss,” which are critical clinical indicators for a pulmonologist. The candidate correctly prioritized the patient’s deteriorating mobility (50-meter limit) over less relevant details like his specific previous occupation beyond its general context.

Conciseness and Clarity

The letter avoids “wordiness.” For example, instead of saying “The patient told me that he has been losing weight and it has been about four kilograms,” the candidate writes “a 4kg weight loss over two months.” This efficient use of language ensures the word count remains within the 180-200 word limit while still providing a comprehensive clinical picture. Irrelevant details, such as the patient’s blood pressure (which is stable) or the lack of allergies, were omitted to maintain focus.

Genre and Style

The tone is appropriately professional and clinical. The use of medical terminology like “exertional dyspnoea,” “accessory muscle use,” and “airflow obstruction” demonstrates that the writer is a healthcare professional communicating with another professional. The candidate correctly uses “Yours sincerely” because the recipient’s name (Dr. Jenkins) is known, adhering to formal letter-writing conventions.

Organisation and Layout

The structure is logical and easy to follow. It begins with the purpose, moves to the clinical history and symptoms, details the examination findings and investigation results, and concludes with the current management and the specific request for the specialist. This “thematic organization” is often more effective than a purely chronological one because it groups related data (like spirometry and X-ray results) together.

Language

The grammar and punctuation are accurate. The candidate uses complex sentence structures effectively, such as “His symptoms significantly worsened over the last month, accompanied by a productive cough…” There are no spelling errors in key medical terms, and the use of tenses—shifting from the past (presented) to the present (appears) and the present perfect (have commenced)—is handled with precision.

Grade B vs Grade C Comparison

Understanding the difference between a Grade B and a Grade C is often about the “nuance” of professional communication. Below is a comparison of how the “Current Presentation” paragraph might look at both levels.

Grade C Version:
Mr. Miller came back today and said he is much worse. He can’t walk more than 50 meters because he gets out of breath. He is coughing up grey stuff and he lost 4kg of weight. He is also not sleeping well because he is wheezing at night. He has smoked for 40 years.

Grade B Version (from our model):
Mr. Miller returned today reporting a significant decline. He now experiences shortness of breath after walking only 50 meters, accompanied by a productive cough and a 4kg weight loss over two months. Notably, he has a 40-year smoking history.

What changed?
The Grade C version uses informal language (“came back,” “grey stuff,” “out of breath”). It also uses simple, repetitive sentence structures (He… He… He…). The Grade B version uses professional synonyms (“significant decline,” “productive cough,” “shortness of breath”) and combines ideas using linking words like “accompanied by” and “notably,” which improves the flow and demonstrates a higher level of linguistic control.

Useful Phrases for Referral Letters

Using standardized medical phrases can help you save time and maintain a professional register during the test. Here are some key phrases specifically useful for the OET medicine referral letter COPD pulmonologist task.

Common Mistakes to Avoid

In my experience as an examiner, candidates often lose marks on preventable errors. When writing a referral for a specialist, avoid these pitfalls:

• Including the entire social history: If the patient’s hobby of stamp collecting isn’t relevant to their COPD, leave it out. Focus on the smoking history and occupational exposures.
• Incorrect Date Format: OET requires specific formats. Use “10 March 2026” or “10/03/2026”. Avoid “March 10th”.
• Misusing the Re: Line: Ensure it contains the name and DOB. Do not put the diagnosis in the Re: line; save that for the opening paragraph.
• Word Count Issues: Writing 250+ words often leads to a lower score in Conciseness and Clarity. It also increases the chance of making grammatical errors.
• Confusion between Referral and Discharge: Ensure you aren’t writing a “summary of care” (discharge) when you should be writing a “request for help” (referral).
• Inappropriate Salutations: If you know the name is Dr. Jenkins, do not write “Dear Sir/Madam.” This affects your Genre and Style score.

Conclusion

Success in the OET medicine referral letter COPD pulmonologist task depends on your ability to synthesize complex case notes into a concise, professional communication. By focusing on the six assessment criteria—particularly Purpose and Conciseness—you can ensure your letter meets the high standards required for a Grade B. Remember to practice with a variety of scenarios, from respiratory cases to psychiatric referrals like those discussed in OET Medicine Speaking: Depression Treatment Options, to build your clinical vocabulary and confidence.
