OET Writing passive voice and medical abbreviations guide

OET Writing: Passive Voice & Medical Abbreviations

Writing an OET letter requires more than simply converting case notes into complete sentences. You need to decide what information matters to the reader, how it should be organised and which language is most suitable for a professional healthcare setting. Grammar and word choice play an important role in making your letter clear and appropriate.

Two areas that often create uncertainty for OET candidates are passive voice and medical abbreviations. Some candidates use passive sentences too frequently because they believe they sound more professional. Others copy abbreviations directly from the case notes without considering whether they are suitable for the recipient.

Neither approach is ideal. The aim should be to communicate clinical information accurately while maintaining a natural professional tone.

What Does Formal Writing Mean in OET?

Formal writing does not mean filling your letter with complicated vocabulary or lengthy grammatical structures. In OET, effective writing is generally clear, focused and appropriate for the healthcare professional receiving the letter.

Your language should reflect the purpose of the correspondence. A referral letter, for example, should clearly explain why the patient needs specialist attention. A discharge letter should help the receiving healthcare professional understand the patient’s treatment and follow-up requirements.

Good OET writing usually has:

A professional tone
Clear sentence structures
Accurate medical terminology
Logical progression of information
Appropriate grammar
Concise expression
Language suited to the recipient

The reader should be able to understand the patient’s situation without having to interpret unnecessary jargon or complicated sentences.

What Is Passive Voice?

Passive voice is a grammatical structure in which the receiver of an action becomes the focus of the sentence.

For example:

Active: The doctor examined the patient.

Passive: The patient was examined by the doctor.

Both sentences communicate the same basic event, but the focus changes. The active sentence emphasises the doctor, while the passive sentence places attention on the patient.

Healthcare communication frequently focuses on what happened to a patient rather than who performed every individual action. For this reason, passive constructions can sometimes be useful in OET letters.

However, passive voice is not automatically better than active voice. It should be selected according to the information you want the reader to notice.

When Should You Use Passive Voice?

The use of passive voice in OET writing can be helpful when the action, procedure or clinical outcome is more important than the person responsible for it.

For instance:

The patient was admitted to the medical ward for further assessment.

The important point is that the patient was admitted and requires further assessment. Identifying the person who admitted the patient adds little value.

Another example is:

An ultrasound scan was performed following her admission.

Here, the investigation is relevant, while the identity of the person who performed it is not.

Passive structures can therefore work well when describing:

Medical procedures
Investigations
Treatments
Hospital admissions
Clinical assessments
Previous interventions
Tests and their results

They allow you to keep the focus on the patient’s clinical history.

When Is Active Voice More Appropriate?

Active voice is often preferable when you need to make an instruction, recommendation or responsibility clear.

Compare these two sentences:

The patient should be reviewed by the physiotherapist.

The physiotherapist should review the patient.

The second sentence identifies exactly who needs to take action. This makes the recommendation more direct.

Active voice is particularly useful when:

Giving advice
Making recommendations
Requesting an assessment
Assigning responsibility
Describing ongoing care
Explaining what should happen next

For example:

Please monitor her blood glucose levels regularly.

This is straightforward and easy for the recipient to act upon.

A strong OET letter does not need to choose between active and passive voice. Good writers use both, depending on the purpose of each sentence.

Do Not Force Passive Structures

One common problem is using passive voice in almost every sentence simply because it appears more formal.

Consider:

It is recommended that the patient be assessed by the doctor and that her medication be reviewed by the nursing team before she is discharged.

Although grammatically acceptable, the sentence is unnecessarily heavy.

A clearer alternative could be:

Please assess the patient and review her medication before discharge.

The second version is shorter and makes the requested actions immediately clear.

Remember that OET assesses your ability to communicate effectively. A complicated sentence is not necessarily a better sentence.

Understanding Medical Abbreviations

Medical professionals use abbreviations extensively in clinical environments. They are convenient when recording information quickly in patient notes.

Examples include BP for blood pressure, HR for heart rate, and ECG for electrocardiogram.

However, the language used in clinical notes is not always suitable for a formal letter. Case notes may contain shorthand that helps healthcare workers record information efficiently, whereas an OET letter should present that information in polished professional language.

This means you should not automatically copy every abbreviation you see in the case notes.

When Can You Use Medical Abbreviations?

The use of medical abbreviations in OET writing depends on the context, the recipient, and how widely recognised the abbreviation is.

Some abbreviations are commonly understood by healthcare professionals and may be appropriate in professional correspondence. For example, ECG is widely recognised in medical communication.

However, unfamiliar abbreviations can create confusion. If the recipient may not immediately understand a shortened term, writing it in full is the safer choice.

For example:

The patient underwent an ECG after experiencing recurrent chest pain.

This is reasonable when communicating with a healthcare professional.

By contrast, if you are writing directly to a patient, using the full term may be more appropriate:

Your electrocardiogram showed no significant abnormality.

The intended reader should always influence your language choices.

Do Not Treat Case Notes as the Final Letter

OET case notes are designed to provide information, not to serve as a ready-made letter. They commonly contain fragments, abbreviations and compressed clinical expressions.

Your task is to transform these notes into coherent communication.

For example, the notes might say:

Pt reports SOB for 3 days. BP 150/95. ECG normal.

Instead of copying this directly, you could write:

The patient has experienced shortness of breath for the past three days. His blood pressure is currently 150/95 mmHg, although his ECG was normal.

The information remains the same, but the presentation is much more appropriate for professional correspondence.

Be Careful With Ambiguous Abbreviations

Not every abbreviation has a universally accepted meaning. Some may be interpreted differently depending on the country, healthcare setting or profession.

For this reason, candidates should avoid unfamiliar shorthand unless its meaning is completely clear and its use is appropriate for the recipient.

You should also avoid informal shortcuts such as:

“pt” instead of patient
“pls” instead of please
“u” instead of you
“meds” when a more precise term is available
“w/” instead of with

These expressions may save space, but they do not demonstrate professional written communication.

Think About the Recipient

The same medical information can require different language depending on who receives the letter.

When writing to a specialist or another healthcare professional, recognised clinical terminology may be suitable. When communicating with a patient, family member or non-specialist, technical language and abbreviations should be limited.

For example, a professional letter could state:

His BP remains elevated despite the current antihypertensive therapy.

For a patient, a clearer alternative would be:

Your blood pressure remains higher than normal despite your current medication.

The difference is not about making one version more formal than the other. It is about making the communication appropriate for the intended reader.

Combining Passive Voice and Abbreviations Naturally

Passive voice and abbreviations can appear together in a professional letter when they genuinely improve communication.

For example:

The patient was admitted following an episode of chest pain. An ECG was performed, and no significant abnormalities were detected. His blood pressure was recorded at 150/95 mmHg. Please review his current medication and advise regarding further management.

The passive structures work because they keep attention on the patient’s clinical events. The abbreviation ECG is also appropriate because it is a commonly recognised medical term.

Notice that the paragraph does not use passive voice or abbreviations simply for the sake of sounding professional. Every choice serves a communication purpose.

How to Make Your Writing Sound Professional

You do not need sophisticated vocabulary to achieve a formal tone. Precision and clarity are more important.

Instead of:

The patient is having a bad problem with breathing.

write:

The patient is experiencing significant shortness of breath.

Instead of:

He was given medicine for his pain.

write:

He was prescribed analgesia for pain relief.

Instead of:

Please check the patient quickly.

write:

I would appreciate your prompt assessment of the patient.

These changes make the writing more professional without making it unnecessarily complicated.

Common Mistakes to Avoid

Several mistakes can affect the quality of your OET letter.

Using passive voice everywhere: Too many passive sentences can make your writing wordy and less direct.

Copying case-note abbreviations: Not every abbreviation in the notes belongs in the final letter.

Using unfamiliar shorthand: If the recipient might misunderstand an abbreviation, write the term in full.

Trying to sound overly academic: OET is a healthcare communication test, not an academic essay examination.

Ignoring the reader: Your vocabulary and terminology should reflect the person receiving the letter.

Writing unnecessarily long sentences: Several short, well-connected sentences are often clearer than one complicated sentence.

A Quick Review Before You Submit

Before completing your OET letter, spend a few moments checking your language choices.

Ask yourself:

Is my tone appropriate for the recipient?
Have I used passive voice only where it serves a purpose?
Have I used active voice when giving instructions or recommendations?
Are my abbreviations widely understood?
Have I avoided unnecessary shorthand?
Have I converted case-note fragments into complete sentences?
Is my writing easy to read?
Have I removed unnecessary information?
Does every sentence contribute to the purpose of the letter?
Does the letter sound like genuine professional communication?

These checks can help you identify problems that may not be obvious while you are writing.

Conclusion

OET Writing rewards candidates who can communicate clinical information clearly and appropriately. Passive voice has a useful role when the action or clinical event deserves more attention than the person performing it. Active voice, meanwhile, is often stronger when you need to give instructions or make responsibilities clear.

Medical abbreviations require similar judgement. Familiar abbreviations can sometimes be suitable when communicating with healthcare professionals, but unclear or unnecessary shorthand should be avoided. The recipient and purpose of the letter should always guide your decision.

The most effective approach is to focus on the reader rather than trying to make every sentence sound formal. Use grammar and terminology because they improve communication, not simply because they appear sophisticated. With regular practice, you can develop a writing style that is professional, concise and natural — exactly what effective OET communication requires.

Frequently Asked Questions

Should I use passive voice in OET Writing?

Yes, but only when it improves clarity. Passive voice is useful when the action, treatment, procedure or clinical event is more important than the person performing it.

Is passive voice more formal for OET?

Not necessarily. Passive voice can sound professional in appropriate situations, but using it excessively can make your sentences lengthy and difficult to understand. Clear communication should always be the priority.

When is active voice better in an OET letter?

Active voice is usually better when giving recommendations, instructions or identifying responsibility. For example, “Please monitor the patient’s blood pressure regularly” is direct and clear.

Can I use medical abbreviations in OET Writing?

Yes, some widely recognised medical abbreviations may be appropriate when writing to healthcare professionals. However, unfamiliar or ambiguous abbreviations should generally be written in full.

Should I copy abbreviations from the OET case notes?

No. Case notes often contain shorthand designed for quick clinical documentation. You should convert the information into clear, professional sentences rather than copying the notes directly.

Which medical abbreviations are commonly used in OET letters?

Commonly recognised abbreviations such as ECG, BP and HR may be appropriate depending on the context and recipient. Candidates should avoid abbreviations that could create confusion.

Should I use abbreviations when writing to a patient?

It is generally better to avoid unnecessary medical abbreviations when communicating with patients. Use plain, understandable language and write medical terms in full when needed.

Can using too many abbreviations affect my OET Writing score?

Excessive or inappropriate abbreviations can make your letter less clear and may affect the effectiveness of your communication. Always choose terminology that the intended reader can understand easily.

How can I make my OET letter sound more formal?

Use precise vocabulary, complete sentences, appropriate linking words and a professional tone. Avoid slang, informal shortcuts and unnecessarily complicated grammatical structures.

What is the most important rule when using passive voice and abbreviations in OET?

Always consider the reader and purpose of the letter. Use passive voice when it helps focus attention on the clinical action, and use abbreviations only when they are appropriate and easily understood by the recipient.
