PSA Testing Discussion with Concerned Patient

Practise this PLAB 2 counselling station on PSA Screening Request. 8-minute voice AI simulation with feedback on all 3 marking domains.

Clinical scenario

You are an FY2 doctor in general practice. Mr Wayne Rutherford, a 58-year-old man, has come to see you requesting a prostate-specific antigen (PSA) test. He is concerned about his prostate cancer risk following his friend's recent diagnosis. Please discuss the benefits and limitations of PSA testing, including false positives and shared decision-making.

Background notes: PMH: Hypertension, Hypercholesterolaemia, Appendectomy age 27, Otherwise healthy

What this station tests

  • Shared decision-making: presenting PSA benefits and limitations honestly without directing the patient's choice
  • Explaining PSA limitations: 75% false positive rate, overdiagnosis of indolent cancers, normal PSA does not exclude cancer
  • Consequences cascade: raised PSA leads to biopsy (risks), which may find indolent cancer (overdiagnosis), leading to treatment (side effects)
  • Distinguishing his friend's diagnosis from his own risk: a friend's cancer does not increase personal risk unless familial
  • Practical PSA preparation advice: avoid ejaculation 48 hours before, no cycling, not during UTI

How to use your 8 minutes

  • 0-1 min — Introduction: Introduce yourself, establish what patient already knows and understands.
  • 1-3 min — Explain Condition: Explain diagnosis or condition using chunk-and-check technique. Use simple language, avoid jargon.
  • 3-5 min — Management Options: Discuss treatment options. Shared decision-making. Risks, benefits, alternatives.
  • 5-7 min — Address Concerns: Explore and address specific concerns. Check understanding. Discuss lifestyle implications.
  • 7-8 min — Closing: Summarise agreed plan. Safety netting. Arrange follow-up. Written information offer.

Consultation approach

The opening

PSA testing stations test shared decision-making: the candidate must present the benefits and limitations of PSA testing honestly so the patient can make an informed choice. The answer is not 'yes, have the test' or 'no, don't have it.' It is a balanced discussion. Mr Rutherford is 58, asymptomatic, requesting PSA because his friend was diagnosed with prostate cancer. Open with: 'Mr Rutherford, I understand you would like to discuss prostate cancer screening. Can you tell me what has prompted this?'

Core approach

Understand his motivation. His friend was diagnosed 3 weeks ago and he is frightened. He wants the PSA test to 'put his mind at ease.' He has no urinary symptoms and feels well. He believes a test will give a clear yes or no answer. This is the misconception that must be gently corrected.

Explain what PSA can and cannot do. 'PSA is a blood test that measures a protein produced by the prostate. It can be raised in prostate cancer, but it is also raised in many benign conditions: an enlarged prostate, a urine infection, or even recent ejaculation. About 3 in 4 men with a raised PSA do not have cancer.' Conversely, some prostate cancers have a normal PSA. It is not a definitive test.

Explain the consequences of a raised result. If PSA is elevated, the next step is a prostate biopsy, which carries risks (bleeding, infection, pain). If cancer is found, it may be a slow-growing cancer that would never have caused symptoms in his lifetime (overdiagnosis). Treatment (surgery, radiotherapy) carries significant side effects (erectile dysfunction, urinary incontinence) that may reduce quality of life for a cancer that might never have harmed him.

Present the benefits. PSA can detect aggressive cancers earlier, when treatment is more effective. Early detection can be life-saving for significant cancers. Reassurance if PSA is low (though not absolute). Frame this as his decision: 'There is no right or wrong answer here. Some men prefer to know, even with the uncertainties. Others prefer not to test.'

Closing and safety netting

Offer a structured decision. 'You do not need to decide today. Take some time to think about what we have discussed. If you decide you want the test, I am happy to arrange it. If you prefer to wait, that is equally valid.' If he wants the test: arrange PSA with the understanding that a raised result will need further investigation. Advise: avoid ejaculation for 48 hours before the test, do not cycle, and test should not be done during active UTI.

Address his friend's diagnosis separately. His concern is driven by his friend's cancer. Reassure that his friend's diagnosis does not increase his own risk (no family link). Safety net: 'Regardless of whether you have the PSA test, if you develop any urinary symptoms, blood in your urine, or bone pain, come in.' Follow-up if he wants time to decide.

How examiners mark this station

Examiners will assess your ability to explain psa screening request and its management in a patient-centred way. Domain 2 (Clinical Management) and Domain 3 (Interpersonal Skills) are equally weighted and primary. Expect marks for accurate information delivery, shared decision-making, chunk-and-check technique, and addressing the patient's specific concerns. Domain 1 (Data Gathering) is assessed through how well you establish the patient's baseline understanding and elicit their concerns.

Domain 1: Data Gathering, Technical and Assessment Skills (Supporting)

Scores well: Confirming he is asymptomatic. Checking family history of prostate cancer. Establishing his understanding of PSA. Checking for urinary symptoms.

Costs marks: Not checking symptoms. Not asking about family history. Not establishing his current understanding.

Domain 2: Clinical Management Skills (Primary focus)

Scores well: Balanced presentation of PSA benefits and limitations. Overdiagnosis and overtreatment explained. Practical preparation advice. Shared decision-making without direction. Safety netting for symptoms regardless of PSA decision.

Costs marks: One-sided presentation. Not explaining overdiagnosis. Being directive. No safety netting.

Domain 3: Interpersonal Skills (Primary focus)

Scores well: Acknowledging his friend's diagnosis as the driver. Allowing time to decide. Not dismissing his concern. Supporting his choice whichever way he decides. Separating his friend's risk from his own.

Costs marks: Dismissing his concern. Pressuring a decision. Not acknowledging his friend's situation. Being paternalistic.

Common examiner feedback (and how to fix it)

Did not provide adequate explanation or plan to the patient

Fix: Use chunk-and-check: deliver one concept, check understanding, then move to the next. Offer all relevant treatment options with risks and benefits before helping the patient decide.

Did not sufficiently recognise or respond to the patient's feelings, concerns, or expectations

Fix: Before and during counselling, explicitly ask what concerns the patient most. Respond to emotional cues with empathic statements before continuing with information.

Common mistakes in this station

  1. Simply arranging the PSA without discussion. PSA is not a routine screening test in the UK. The candidate must have the shared decision-making conversation before ordering it. Candidates who just request the blood test skip the core of the station.
  2. Being directive in either direction. Telling him 'you should have the test' or 'you don't need the test' removes his autonomy. The correct approach is balanced information followed by his choice.
  3. Not explaining overdiagnosis and overtreatment. The risk of PSA is not just the false positive rate. It is the cascade: finding a slow cancer, treating it unnecessarily, and causing erectile dysfunction or incontinence. Candidates who mention false positives without the treatment consequences provide incomplete counselling.

Resitting PLAB 2?

If counselling stations have been a challenge, the most common issue is information overload: delivering too much clinical detail without checking understanding. Practise the chunk-and-check technique until it becomes automatic. Remember that shared decision-making, not lecturing, is what scores highly in Domain 3.

Example opening

Hello, my name is Dr [Name]. I understand you've come in today to discuss [topic]. Before I explain things, could you tell me what you've been told so far, so I know where to start?

Can I do well in this station without real-world experience of PSA screening request?

Structure beats experience here. Focus on explaining PSA limitations: 75% false positive rate, overdiagnosis of indolent cancers, normal PSA does not exclude cancer. Use the domain breakdown on this page to target your preparation, then practise the station aloud so your structure survives exam pressure.
