How to Take a Medical History in an OSCE
Taking a good medical history is one of the most important skills you will learn in medical school. In OSCEs, the history often gives you most of the diagnosis before you examine the patient or see any investigations.
But this is not just an OSCE skill. The habits you build when learning to take a history will stand to you later as a doctor. A good social history is a great example. Early on, it can feel like a box-ticking exercise — smoking, alcohol, who lives at home — but in real life it can completely change your thinking. For example, if you are considering tuberculosis, asking about travel, close contacts, housing and living conditions can give you important clues that you would miss if you rushed past the social history.
The challenge is that students often know the structure, but struggle to make it sound natural. They either rush into closed questions, forget to explore the presenting complaint properly, or leave key areas like ICE and social history until the end when they have run out of time.
This guide will walk through a simple, practical structure for taking a medical history in an OSCE.
1. First Impressions Matter
The history starts before you ask your first clinical question.
When you enter the station, try to look calm, confident and organised. Knock, enter the room, smile, introduce yourself clearly and focus on the patient.
This might sound basic, but it matters. If you walk in looking nervous, unsure, or distracted by the examiner, it can make the consultation feel awkward from the start.
A simple opening might be:
“Hello, my name is Peter. I’m one of the medical students. Could I just check your name and date of birth please?”
Then explain what you are going to do:
“Today I’d like to ask you some questions about your health and what has brought you in. Is that okay?”
This covers the basics:
-
Introduce yourself
-
Confirm the patient’s identity
-
Explain what you are doing
-
Gain consent
2. Start with an Open Question
Once you have introduced yourself, start broad.
For example:
“Can you tell me what has brought you in today?”
Then let the patient speak.
A common mistake is accidentally closing down your own open question. For example:
“Can you tell me what has brought you in today — was it chest pain?”
That is no longer an open question. You have already pushed the patient in a particular direction.
In OSCEs, simulated patients are usually trying to help you. If you give them space at the start, they will often give you useful information about their symptoms, their concerns, and why they have come in.
Even 30 seconds of silence can be useful. It gives the patient time to speak, and it gives you a moment to settle your nerves and think about where the history is going.
3. Explore the Presenting Complaint
The presenting complaint is the main symptom or problem that brought the patient in.
-
Examples include:
-
Chest pain
-
Shortness of breath
-
Headache
-
Collapse
-
Abdominal pain
-
Cough
-
Weight loss
-
Tiredness
Once you know the presenting complaint, your job is to explore it properly.
Do not jump straight into past medical history or medications. First, understand the symptom in front of you.
Once you know the presenting complaint, your next job is to explore it properly.
A simple way to explore most symptoms is to use OPERA:
-
O — Onset: When did it start? Did it come on suddenly or gradually?
-
P — Progression: Has it been getting better, worse or staying the same?
-
E/R — Exacerbating and relieving factors: Is anything making it better or worse?
-
A — Associated symptoms: Have they noticed any other symptoms alongside it?
This works well for symptoms like cough, breathlessness, dizziness, tiredness or palpitations.
For example, if the patient presents with shortness of breath, you might ask:
-
“Have you noticed any triggers?”
-
“How long does it last for?”
-
“Is it there all the time, or does it come and go?”
4. If the symptom is pain, use SOCRATES
Pain needs a bit more detail, so SOCRATES is a useful pain-specific framework.
SOCRATES stands for:
S — Site: “Where exactly is the pain?”
O — Onset: “When did it start? Was it sudden or gradual?”
C — Character: “How would you describe the pain?”
R — Radiation: “Does it move anywhere else?”
A — Associated symptoms: “Did you notice anything else with it, such as shortness of breath, sweating, nausea or dizziness?”
T — Timing: “Is it there all the time or does it come and go?”
E — Exacerbating and relieving factors: “Does anything make it better or worse?”
S — Severity: “On a scale of 0 to 10, how severe is it?”
A simple way to think about it is: OPERA works for most symptoms; SOCRATES is what you use when the symptom is pain.
5. Do not forget ICE
ICE stands for:
-
Ideas
-
Concerns
-
Expectations
This is about understanding the patient’s perspective.
Students sometimes leave ICE until the very end and ask it in a robotic way:
“What are your ideas, concerns and expectations?”
That can sound unnatural.
A better way is to integrate it into the consultation.
For example:
“I’ve been listening to everything you’ve said, and I’ll take it seriously. Is there anything in particular you are worried this could be?”
Or:
“Had you any thoughts yourself about what might be causing this?”
Or:
“What were you hoping we might be able to do for you today?”
ICE is not just there for marks. It often tells you why the patient has really come in.
For example, a patient with a cough may be worried because a family member recently died of lung cancer. If you do not ask, you may never find out what is actually driving their concern.
6. Respond to Concerns Properly
If a patient tells you they are worried about something serious, do not ignore it and rush on.
For example, if the patient says:
-
“I’m worried this could be cancer because my dad died of bowel cancer.”
-
You could respond with:
-
“I’m really sorry to hear that. That must have been very difficult. I can understand why this is worrying you. I’ll take that seriously. I’d like to ask a few more questions so we can work out what the best next steps are.”
This shows empathy without making promises or jumping to conclusions.
7. If Needed, Do a Quick Head-to-Toe Screen
The purpose of this section is to explain that most important associated symptoms should already have been explored during the history of the presenting complaint.
However, if the student is still unsure what might be going on, it can be useful to quickly think through the patient from head to toe to make sure an important symptom has not been missed.
Give a few short examples such as:
-
Neurological: headache, dizziness, weakness or visual symptoms
-
Cardiorespiratory: chest pain, palpitations, breathlessness or cough
-
Gastrointestinal: abdominal pain, vomiting or change in bowel habit
-
Genitourinary: dysuria, frequency or haematuria
-
Skin/MSK: rash, joint pain or muscle pain
The important message is that this should be quick and focused.
Please make it clear that:
-
Students do not need to work through every system in every history;
-
A long systems review can waste valuable OSCE time;
-
This is mainly a useful safety net when the presentation is unclear.
This section should sit before Past Medical and Surgical History, rather than later in the consultation.
8. Past Medical and Surgical History
Next, ask about previous medical conditions and operations.
Start generally:
-
“Do you have any medical conditions?”
-
“Have you ever had any operations or been in hospital before?”
Then ask specifically about conditions relevant to your differential diagnosis.
For example, in chest pain, you should ask about:
-
Previous heart attack
-
Angina
-
High blood pressure
-
Diabetes
-
High cholesterol
-
Stroke or TIA
-
Previous blood clots
In abdominal pain, you might ask about:
-
Previous abdominal surgery
-
Gallstones
-
Inflammatory bowel disease
-
Diverticular disease
-
Cancer history
A good OSCE answer is not just “past medical history?” It is asking the general question, then asking the specific risk-factor questions that fit the presentation.
9. Drug History and Allergies
Ask about regular medications.
“Do you take any regular tablets, inhalers, creams, injections or over-the-counter medications?”
It can also be useful to ask:
“Do you take anything from the pharmacy or any herbal remedies?”
For relevant medications, ask whether the patient is actually taking them as prescribed. In real life, many patients do not take medications exactly as written.
Then ask about allergies:
“Do you have any allergies?”
If they do, clarify the reaction:
“What happens when you take it?”
This is important because “allergy” can mean anything from nausea to anaphylaxis.
10. Family History
Ask about relevant conditions in the family.
“Do any conditions run in the family?”
Then make it specific.
In chest pain:
“Is there any family history of heart attacks, angina, strokes or sudden cardiac death?”
In bowel symptoms:
“Is there any family history of bowel cancer or inflammatory bowel disease?”
Try to ask sensitive questions carefully.
“I don’t want to worry you, but these are questions we ask everyone with these symptoms. Has anyone in your family had bowel cancer?”
11. Social History
Social history is not just smoking and alcohol. It helps you understand the patient’s life, risk factors, function and support.
Useful areas include:
Living situation
-
Do they live alone?
-
House, flat, care home or nursing home?
-
Who is at home with them?
-
Do they have carers?
Function
-
Are they independent with washing and dressing?
-
Can they cook and shop?
-
Do they use mobility aids?
-
Do they drive?
Occupation
-
What do they do for work?
-
Any relevant occupational exposures?
-
Are symptoms affecting their work?
Smoking
-
Ask whether they smoke, how much, and for how long.
-
Pack years can be calculated as:
-
Number of cigarettes per day divided by 20, multiplied by the number of years smoked.
-
For example, 20 cigarettes per day for 10 years equals 10 pack years.
Alcohol
-
Ask how much they drink in a typical week.
-
Try to calculate approximate weekly units if relevant.
Recreational drugs
-
Ask if relevant, especially in presentations such as chest pain, collapse, mental health problems or unexplained symptoms in younger patients.
Other relevant areas
-
Depending on the presentation, you may also ask about:
-
Travel
-
Pets
-
Hobbies
-
Sexual history
-
Diet
-
Exercise
The key is to make the social history relevant. For an older patient with a fall, their baseline mobility and home supports may be just as important as the diagnosis.
12. Summarise and Close
At the end of the history, summarise the key points back to the patient. This shows that you listened and gives the patient a chance to correct or add anything.
For example:
“Just to summarise, you have had central chest pain since this morning, which came on suddenly while walking. It felt tight, moved to your left arm, and was associated with sweating and nausea. You have a history of high blood pressure and diabetes, and your father had a heart attack at a young age. Is that an accurate summary?”
Then ask:
“Is there anything important I have missed?”
If you are running out of time in an OSCE, it is still worth saying:
“I would like to summarise the key points back to the patient and check if there is anything I have missed.”
You may still pick up a mark for showing that you know what you should do.
13. A Simple OSCE History Structure
A simple structure to remember is:
-
Introduction and consent
-
Open question
-
Presenting complaint and history of presenting complaint
-
OPERA, or SOCRATES if the symptom is pain
-
Quick focused head-to-toe screen if needed
-
Past medical and surgical history
-
Drug history and allergies
-
Family history
-
Social history
-
ICE and patient perspective
-
Summary and closing
You do not need to sound like a robot. The structure is there to help you, not to replace a normal conversation.
The best histories feel organised, safe and human.
