Post-Exposure Prophylaxis Counselling

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

Clinical scenario

You are an FY2 doctor in sexual health services. Ms Zara Obi, a 26-year-old woman, has attended following notification that her ex-partner was diagnosed with meningococcal meningitis three days ago. She is anxious and requesting advice on her risk and what precautions to take.

Background notes: PMH: Nil significant

What this station tests

  • Correct close contact definition: shared household and intimate contact within 7 days qualifies for prophylaxis
  • First-line prophylaxis choice: ciprofloxacin 500mg single dose, considering the OCP interaction that makes rifampicin less suitable
  • Proportionate risk communication: elevated risk but small in absolute terms, with prophylaxis reducing it further
  • Vaccination does not replace prophylaxis: explaining why she still needs antibiotics despite being vaccinated
  • Glass test safety netting: teaching the non-blanching rash test alongside other meningitis warning signs

How to use your 8 minutes

Consultation approach

The opening

Post-exposure prophylaxis counselling requires balancing urgency (she needs antibiotics now) with accurate risk communication (the risk is elevated but not huge). The candidate must avoid both false reassurance and unnecessary alarm. Ms Obi is 26, attending after being notified that her ex-partner was diagnosed with meningococcal meningitis three days ago. She is anxious and currently symptom-free. Open with: 'Zara, I understand you have been contacted about your ex-partner's diagnosis. Tell me what you have been told so far, and what is worrying you most.'

Core approach

Establish the exposure. She dated him for six weeks, lived together during that time, and had intimate contact approximately one week ago. She qualifies as a close contact (shared household, intimate contact within 7 days of the index case). She was notified 3 days after his admission. Prophylaxis is most effective within 24 hours but is still recommended up to 7 days.

Explain the risk proportionately. 'Being a close contact means your risk of developing meningococcal disease is higher than the general population, but it is still relatively small. Prophylactic antibiotics significantly reduce this risk further. The incubation period is 2 to 10 days, so the fact that you are well now is reassuring but does not completely rule out infection.'

Prescribe prophylaxis. First-line: ciprofloxacin 500mg single dose orally (simplest, can be given now). Alternative: rifampicin 600mg BD for 2 days. Important: she takes the combined oral contraceptive pill. Rifampicin reduces OCP efficacy (enzyme inducer). If rifampicin is used, she needs additional contraception for the remainder of the pill cycle. Ciprofloxacin does not have this interaction, making it the better choice for her.

Address her specific concerns. Her vaccination status (MenB, MenC, MenACWY) does not replace prophylaxis. Vaccination protects against future exposure but does not clear current carriage. Her flatmates do not need prophylaxis unless they also had close contact with the index case. She does not need to isolate from them.

Closing and safety netting

Symptom awareness is the critical safety netting. 'Over the next 7 to 10 days, watch for: high fever, severe headache, neck stiffness, dislike of bright lights, a rash that does not fade when pressed with a glass (do the glass test), drowsiness or confusion, or vomiting. If you develop any of these, go to A&E immediately and tell them you are a meningococcal contact.'

Address the emotional dimension. Her ex-partner is seriously ill. She is frightened for herself and worried about him. Acknowledge both: 'I understand this must be very worrying, both for your own health and for your ex-partner. The prophylaxis significantly reduces your risk.' Offer follow-up if she develops any symptoms or has further questions. Give the meningitis charity helpline number.

How examiners mark this station

Examiners will assess your ability to explain meningococcal meningitis 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: Establishing exposure timeline and type (household, intimate contact, timing). Confirming she is currently asymptomatic. Checking vaccination status. Checking contraception. Asking about flatmates' exposure level.

Costs marks: Not establishing the exposure timeline. Not checking contraception. Not assessing current symptom status.

Domain 2: Clinical Management Skills (Primary focus)

Scores well: Correct prophylaxis choice (ciprofloxacin, considering OCP). Proportionate risk communication. Correct advice that vaccination does not replace prophylaxis. Specific symptom awareness including glass test. Clear timeframe for monitoring (7 to 10 days). A&E instruction if symptoms develop.

Costs marks: Wrong prophylactic agent or dose. Not considering OCP interaction. Over- or under-stating risk. Not teaching the glass test. No timeframe for monitoring.

Domain 3: Interpersonal Skills (Throughout)

Scores well: Acknowledging her anxiety about both her own health and her ex-partner. Proportionate reassurance without dismissing the risk. Clear, practical safety netting she can act on. Offering the meningitis charity helpline.

Costs marks: Dismissing her anxiety. Being overly clinical about a frightening situation. Not acknowledging her concern about her ex-partner. No follow-up plan.

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 checking her contraception before choosing the prophylactic antibiotic. Rifampicin is an enzyme inducer that reduces OCP efficacy. Ciprofloxacin does not have this interaction. Candidates who prescribe rifampicin without checking contraception risk an unplanned pregnancy.
  2. Being either too reassuring or too alarming about the risk. Saying 'you'll be fine, don't worry' is inaccurate (the risk is real). Saying 'this is very dangerous' is disproportionate (the absolute risk is small with prophylaxis). The correct balance is: 'your risk is elevated but small, and prophylaxis reduces it further.'
  3. Not explaining that vaccination does not replace prophylaxis. She is fully vaccinated and may assume she is protected. Candidates must explain that vaccination prevents future infection but does not clear current nasopharyngeal carriage.

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?

Where do candidates most often go wrong in this station?

Not checking her contraception before choosing the prophylactic antibiotic. Rifampicin is an enzyme inducer that reduces OCP efficacy. Ciprofloxacin does not have this interaction.

Can I do well in this station without real-world experience of meningococcal meningitis?

Structure beats experience here. Focus on first-line prophylaxis choice: ciprofloxacin 500mg single dose, considering the OCP interaction that makes rifampicin less suitable. Use the domain breakdown on this page to target your preparation, then practise the station aloud so your structure survives exam pressure.
