Crisis Prevention and Management in Sickle Cell Disease

Practise this PLAB 2 counselling station on Sickle Cell Disease. 8-minute voice AI simulation with feedback on all 3 marking domains.

Clinical scenario

You are an FY2 doctor in a haematology clinic. Mr Kofi Musa, a 28-year-old man with sickle cell disease, is attending for routine follow-up. He has had three sickle cell crises in the past eighteen months and is struggling to manage his condition. He has concerns about his work situation and wants to discuss how to prevent crises. Please counsel him about crisis prevention, triggers, and emergency management.

Background notes: PMH: Sickle cell disease HbSS (diagnosed age 3 months), History of multiple vaso-occlusive crises (3 in past 18 months)

What this station tests

  • Identifying modifiable crisis triggers through review of recent episodes: cold exposure, infection, and dehydration
  • Hydroxyurea counselling: mechanism (increases HbFb, reduces sickling), efficacy (50% crisis reduction), side effects (fertility, monitoring)
  • Employment rights: Equality Act 2010 disability protection and reasonable adjustments
  • Genetic counselling: partner testing, inheritance risk, and sperm banking option before hydroxyurea
  • Acute chest syndrome safety netting: chest pain with fever as a life-threatening emergency

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

Sickle cell counselling requires understanding the patient's lived experience with a lifelong condition, not just delivering textbook prevention advice. The candidate must address triggers, pharmacological prevention, and the psychosocial burden. Mr Musa is 28, HbSS, has had 3 crises in 18 months, and is struggling with work impact. Open with: 'Kofi, how have things been since your last crisis? Tell me what is on your mind.' Let his concerns lead the consultation.

Core approach

Review his recent crises for trigger patterns. First: working in cold storage area of warehouse, long shifts. Second: intercurrent infection. Third: dehydration during summer. Cold, infection, and dehydration are the three most common modifiable triggers. He knows this but is frustrated by the unpredictability. His employer is questioning his reliability, which adds work stress.

Discuss hydroxyurea (hydroxycarbamide). This is the key pharmacological intervention. It increases fetal haemoglobin, reduces sickling, and cuts crisis frequency by approximately 50%. He may have concerns about side effects, particularly fertility (it is teratogenic and can reduce sperm count). Address these honestly: fertility effects are usually reversible on stopping, but sperm banking is an option if he is planning children. Monthly blood monitoring is required.

Practical trigger avoidance: negotiate with employer about cold storage exposure (occupational health referral), maintain hydration (especially during physical work), flu vaccination annually, prompt antibiotic treatment for infections, avoid extreme temperature changes.

Address the genetic concern. He is in a stable relationship and worried about passing sickle cell to children. His partner needs testing for sickle cell trait. If she is a carrier, each child has a 25% chance of HbSS disease. Genetic counselling referral.

Closing and safety netting

Recommend starting hydroxyurea given 3 crises in 18 months (NICE threshold for consideration). Explain monitoring: monthly FBC initially, then 3-monthly once stable. Discuss employment rights: sickle cell disease is a disability under the Equality Act 2010, and reasonable adjustments (avoiding cold areas, flexible leave for crises) are a legal requirement.

Offer partner testing and genetic counselling for family planning. Signpost to the Sickle Cell Society for support, peer networks, and employment advice. Crisis action plan: early hydration, warmth, analgesia at home, and when to attend hospital (pain not responding to home analgesia within 30 minutes, fever, chest symptoms). Safety net: 'If you develop chest pain with fever, this could be acute chest syndrome and you must go to A&E immediately.' Follow-up in 4 weeks.

How examiners mark this station

Examiners will assess your ability to explain sickle cell disease 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: Recent crises reviewed with trigger identification. Current baseline assessment (Hb, reticulocytes, renal function). Work environment assessed (cold storage). Relationship and family planning status explored. Current medications reviewed.

Costs marks: Not reviewing crisis triggers. Not assessing work environment. Not asking about family planning.

Domain 2: Clinical Management Skills (Primary focus)

Scores well: Hydroxyurea recommended with honest side effect discussion. Monitoring plan (monthly FBC). Trigger avoidance with practical workplace solutions. Partner testing and genetic counselling. Acute chest syndrome warning. Crisis action plan.

Costs marks: Not recommending hydroxyurea. Not discussing fertility. No crisis action plan. No acute chest syndrome warning.

Domain 3: Interpersonal Skills (Primary focus)

Scores well: Understanding his frustration with unpredictability. Empowering with employment rights knowledge. Addressing genetic concerns sensitively. Acknowledging the burden of lifelong disease management. Practical support signposting.

Costs marks: Generic prevention advice ignoring his specific context. Not addressing work stress. Dismissing his frustration. Not empowering with rights knowledge.

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. Not discussing hydroxyurea. Three crises in 18 months meets the threshold for pharmacological prevention. Candidates who focus only on lifestyle modification without offering hydroxyurea miss the most effective intervention.
  2. Not addressing the fertility concern. Hydroxyurea is teratogenic and can affect sperm count. A 28-year-old in a stable relationship needs this discussed before starting treatment. Candidates who prescribe without mentioning fertility demonstrate inadequate counselling.
  3. Not mentioning employment rights. His employer is questioning his reliability. Sickle cell disease is protected under the Equality Act. Candidates who do not empower him with this knowledge leave him vulnerable at work.

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?

Frequently asked questions

How should I approach sickle cell disease counselling in this PLAB 2 station?

Sickle cell counselling requires understanding the patient's lived experience with a lifelong condition, not just delivering textbook prevention advice. The candidate must address triggers, pharmacological prevention, and the psychosocial burden. Mr Musa is 28, HbSS, has had 3 crises in 18 months, and is struggling with work impact.

What are examiners marking in this sickle cell disease station?

Marks are won for: Recent crises reviewed with trigger identification. Current baseline assessment (Hb, reticulocytes, renal function). Work environment assessed (cold storage). Marks are lost for: Not reviewing crisis triggers. Not assessing work environment. Not asking about family planning.

What is the most common mistake candidates make in this sickle cell disease station?

Not discussing hydroxyurea. Three crises in 18 months meets the threshold for pharmacological prevention. Candidates who focus only on lifestyle modification without offering hydroxyurea miss the most effective intervention.

How do I prepare for this station if I have not managed sickle cell disease in clinical practice?

Structure beats experience here. Focus on hydroxyurea counselling: mechanism (increases HbFb, reduces sickling), efficacy (50% crisis reduction), side effects (fertility, monitoring). Work through the consultation approach above, then rehearse it aloud under the 8-minute time pressure so the structure holds up in the exam.
