ROLE PLAYER INSTRUCTIONS

Just like a consultation with a doctor, the candidate will ask you a series of questions.
The OPENING LINE is always to be said exactly as written. This is the only part of the script
which will be the same for all candidates. Where the candidate goes after the opening line is
up to them.

The remainder of the information is to be given based on the questions asked by the
candidate.

The information in the following script are core pieces of information. The core pieces of
information will not necessarily follow the order in the script but should be given when cued
by the candidate’s question.

GENERAL INFORMATION can be given relatively freely. After the opening line, most
candidates will ask an open question like “Can you tell me more about that?” You can provide
the GENERAL INFORMATION in response to that sort of question.

SPECIFIC INFORMATION should only be given when the candidate asks a relevant question.
Candidates don’t need to ask for all the information in the SPECIFIC INFORMATION section,
but all the relevant information is given there should they want to.

Each line or dot point in the SPECIFIC INFORMATION section is an appropriate chunk of
information which can be provided to the candidate when asked a relevant question.

Do not give extra information than asked.

Do not provide details which are not given in the information chunks (i.e.: do not elaborate
or ad-lib).

If the candidate asks a question that is not given in the script, the best way to respond is with
a generic response indicating there is no problem. For example:

Candidate: “How many hours do you sleep?”
Response: “I’m sleeping fine.” / “I don’t have any concerns about my sleep.”

The case may have specific QUESTIONS to ask the candidate. You can start asking the
QUESTIONS if the candidate asks about your ideas or concerns or questions.

Ask the other questions in a conversational way. You do not need to ask all the questions. The
aim should be to ask most of the questions but without interrupting the candidate.

The Patient Record Summary is also included. This is not part of the script but is included for
your general information.

If you need help in understanding any of the medical information in the script, ask the College
examiner who will be with you, and they can help to explain the terms or the conditions.


ROLE-PLAYER SCRIPT

Opening Line

“Doctor, my right hand has been going numb at night, and it’s getting worse. I’m worried about work.”


General Information

(Freely given if the candidate asks open-ended questions like “Can you tell me more about that?”)

  • The symptoms started about three months ago.
  • It began as occasional tingling and numbness in the thumb, index, and middle fingers.
  • Over the last few weeks, the numbness has worsened and is now waking me up at night.
  • I have to shake my hand or move my wrist to make the numbness go away.

Specific Information

(Only given when the candidate asks direct questions)

Background Information

  • The pain sometimes radiates up my forearm.
  • My grip strength feels weaker—I’ve noticed I’m dropping tools more often at work.
  • I use power tools every day—a lot of repetitive work, hammering, and using a jackhammer.
  • I sometimes feel a bit of stiffness in my neck, but no severe neck pain.
  • It’s affecting my sleep and making me more tired during the day.
  • I haven’t seen anyone about this before—I thought it would go away.
  • It’s getting to the point where I can’t ignore it anymore.

Occupational Impact

  • I work as a construction worker, and I use my hands constantly.
  • I do a lot of gripping, lifting, and vibrating tool use (e.g., drills, hammers, jackhammers).
  • My boss has noticed me struggling and asked if I’m okay.
  • I’m worried that if I can’t do my job properly, I might lose work.
  • I haven’t told my employer about it yet—I don’t want them to think I’m not fit for the job.
  • I feel frustrated and anxious because I can’t afford to take time off work.

Medical History & Risk Factors

  • I was diagnosed with type 2 diabetes five years ago.
  • My diabetes is mostly stable, but I don’t always check my blood sugars.
  • I know that diabetes can cause nerve problems, but I thought that mostly affected the feet.
  • I smoke 10 cigarettes a day, have been smoking since my early 20s.
  • I know I could lose some weight—I’m about 95kg, and I’m 175cm tall (BMI 31).
  • I don’t exercise much outside of work—I’m usually too tired after a long shift.
  • My dad has diabetes, and my mum has arthritis.

Current Management & Self-Treatment

  • I’ve been taking paracetamol, but it doesn’t seem to do much.
  • I massage my hand when it goes numb—it helps a little.
  • I tried wearing a wristband, but it didn’t make a difference.
  • I’ve never used a wrist splint—do they work?
  • I haven’t taken any time off work yet, but I’m starting to struggle.
  • I haven’t had any scans or tests done—do I need one?

Patient’s Concerns & Expectations

  • “Is this serious? Could it be something worse?”
  • “Do I need to have surgery? I’ve heard of people getting operations for this.”
  • “Is this from my job? If I keep working like this, will it get worse?”
  • “Will I have to stop working? I really can’t afford time off.”
  • “Are there exercises or treatments I can do at home?”
  • “If I lose weight or stop smoking, will that help?”
  • “Should I be worried about diabetes affecting my nerves?”
  • “Do I need a scan or an X-ray?”

Emotional Responses & Body Language

  • Appears worried and frustrated—anxious about the future of his job.
  • Looks uncomfortable, occasionally shakes his right hand while talking.
  • Frowns when discussing sleep problems, rubbing his eyes occasionally.
  • Leans forward when talking about work concerns, making eye contact.
  • Shows mild frustration when discussing pain management, sighing.
  • Nods when given information, but if unclear, asks “What does that mean?”

Final Patient Expectations

  • Wants clear advice on whether he can keep working.
  • Hopes for a treatment plan that doesn’t involve surgery.
  • Would consider lifestyle changes (like quitting smoking or losing weight) if it will help.
  • Wants to know if he needs to see a specialist.
  • Prefers conservative treatment first before considering drastic measures.

THE COMPETENT CANDIDATE

The competent candidate should be able to:


Task 1: Take a focused history regarding the patient’s symptoms, occupational impact, and risk factors.

The competent candidate should:

  • Establish the onset, duration, and progression of symptoms, including numbness, tingling, and pain in the thumb, index, and middle fingers.
  • Identify aggravating and relieving factors—such as repetitive hand use, night-time symptoms, and relief from shaking the hand.
  • Ask about functional impact, including difficulty gripping tools and interference with work.
  • Explore occupational risk factors, such as vibrating tool use, repetitive wrist movements, and prolonged gripping.
  • Assess general health and comorbidities, particularly diabetes, obesity, and smoking, which increase the risk of median nerve dysfunction.
  • Check for differential diagnoses, including cervical radiculopathy, peripheral neuropathy, and arthritis, by asking about neck pain, other limb symptoms, and joint issues.
  • Consider red flags such as bilateral symptoms, muscle wasting, or systemic signs that might indicate more severe pathology.
  • Address patient concerns, particularly job security and fears about surgery.

Task 2: Explain your differential diagnosis to the patient, ensuring clarity and addressing concerns.

The competent candidate should:

  • Explain that carpal tunnel syndrome (CTS) is the most likely diagnosis, given the numbness, tingling, and weakness in a median nerve distribution, worsening at night.
  • Discuss work-related factors that may have contributed, such as vibration, repetitive strain, and hand positioning.
  • Mention other possible causes, including:
    • Cervical radiculopathy (if there were neck pain or symptoms extending beyond the hand).
    • Diabetic peripheral neuropathy (if symptoms were bilateral or affecting other nerves).
    • Rheumatoid arthritis or osteoarthritis (if there was joint pain and stiffness).
  • Address patient concerns, reassuring that many cases improve with conservative treatment and that surgery is not always needed.

Task 3: Discuss the management plan, including conservative treatment options, work modifications, and follow-up care.

The competent candidate should:

  • Recommend wrist splinting at night, which has strong evidence for symptom relief in mild-to-moderate CTS.
  • Suggest NSAIDs for pain relief, though they are not curative.
  • Advise reducing repetitive hand strain, including:
    • Ergonomic adjustments (e.g., using padded gloves, alternating tasks).
    • Taking breaks from repetitive movements.
  • Provide exercises and stretches to reduce pressure on the median nerve.
  • Address modifiable risk factors, such as:
    • Smoking cessation, which may improve nerve healing.
    • Optimising diabetes control to prevent worsening neuropathy.
    • Weight loss, if applicable, to reduce median nerve compression.
  • Explain that steroid injections or surgical referral may be considered if symptoms persist or worsen.
  • Arrange follow-up in 4-6 weeks to assess progress and consider referral if symptoms remain disabling.

Task 4: Outline indications for referral to a specialist if necessary.

The competent candidate should:

  • Recognise that most mild-to-moderate CTS cases improve with conservative measures.
  • Identify indications for specialist referral, including:
    • Failure of conservative treatment after 6-12 weeks.
    • Severe symptoms (persistent numbness, constant pain, weakness affecting daily activities).
    • Signs of nerve damage (e.g., muscle wasting of the thenar eminence, significant weakness).
    • Diagnostic uncertainty, such as atypical symptoms or suspected underlying neurological disease.
  • Discuss nerve conduction studies as a diagnostic tool before surgery.
  • Reassure that surgery (carpal tunnel release) is effective but only necessary for severe or persistent cases.

SUMMARY OF A COMPETENT ANSWER

  • Takes a detailed history including symptom progression, occupational impact, and risk factors.
  • Explains the differential diagnosis clearly, emphasising CTS while ruling out other conditions.
  • Develops a structured management plan including conservative measures, lifestyle modifications, and work adjustments.
  • Identifies appropriate referral criteria, ensuring specialist involvement when necessary.
  • Uses patient-centred communication, addressing concerns about work, treatment options, and prognosis.

PITFALLS

  • Failing to ask about occupational risk factors, which are critical in this case.
  • Not considering differential diagnoses, particularly cervical radiculopathy or diabetic neuropathy.
  • Jumping to surgical management too soon, without attempting conservative measures first.
  • Neglecting patient concerns about job security and fear of losing function.
  • Not addressing lifestyle factors, such as smoking, diabetes, and obesity, which can worsen neuropathy.
