MRSA Colonisation Identified in Hospital Screening

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

Clinical scenario

You are an FY2 doctor in an infectious diseases outpatient clinic. Mr Lewis Garrett, a 62-year-old man, has attended following discharge from hospital where routine screening identified methicillin-resistant Staphylococcus aureus (MRSA) colonisation. He is well with no active infection. Please counsel him about MRSA colonisation, the implications, decolonisation therapy, hygiene measures, and infection control precautions.

Background notes: PMH: Osteoarthritis left knee, Hypertension, Hypercholesterolaemia, T2DM

What this station tests

  • Distinguishing colonisation from infection: MRSA on the skin without causing illness versus active MRSA disease
  • Addressing the media-driven fear: MRSA colonisation is not a death sentence, many healthy people carry it
  • Decolonisation protocol: chlorhexidine body wash plus mupirocin nasal ointment for 5 days
  • Practical advice: normal activities can continue, good hand hygiene, inform future healthcare providers
  • Family reassurance: healthy family members are not at risk from normal household contact

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

MRSA colonisation counselling requires distinguishing colonisation from infection, addressing the patient's fear (many patients equate MRSA with death), and providing practical hygiene advice. Mr Garrett is 62, well after elective knee replacement, found to be MRSA colonised on routine screening. Open with: 'Mr Garrett, I understand the screening found MRSA and you have questions. Let me explain what this means.'

Core approach

Explain the critical distinction. 'Colonisation means the MRSA bacteria are living on your skin or in your nose without causing any illness. This is very different from an MRSA infection, where the bacteria cause active disease. You are well, your surgical wound is healing normally, and you do not have an infection.'

Address his main fears. He thinks MRSA is a death sentence (media portrayal). Reassure: 'Many healthy people carry MRSA without ever becoming ill. The bacteria only cause problems if they get into a wound or into the bloodstream.' He worries about infecting his grandchildren. Reassure: 'MRSA colonisation does not pose a risk to healthy family members. Normal household hygiene is sufficient.'

Decolonisation treatment. Body wash with chlorhexidine (or octenidine) for 5 days. Mupirocin nasal ointment three times daily for 5 days (if nasal carriage confirmed). This aims to eradicate the colonisation, though it does not always work permanently.

Practical advice: good hand hygiene, keep any wounds covered, inform healthcare providers about MRSA status before any future procedures or hospital admissions.

Closing and safety netting

Reassure about daily life: 'You can continue all your normal activities, including seeing your grandchildren, going to the community centre, and socialising. MRSA colonisation does not require isolation at home.' His volunteering at the community centre can continue.

Future healthcare: 'If you are admitted to hospital again, let them know about the MRSA screening result so they can take appropriate precautions.' This is about protecting him (ensuring his surgical site is managed with MRSA awareness) not about protecting others from him.

Follow-up: repeat screening swabs after decolonisation treatment to check clearance. Safety net: 'If you develop redness, swelling, or discharge around your knee wound, or develop a fever, come in urgently.' Follow-up in 2 weeks.

How examiners mark this station

Examiners will assess your ability to explain mrsa colonisation 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 colonisation not infection. Checking screening sites. Reviewing surgical wound status. Assessing household contacts. Checking current medications.

Costs marks: Not distinguishing colonisation from infection. Not checking wound status.

Domain 2: Clinical Management Skills (Primary focus)

Scores well: Colonisation versus infection explained. Decolonisation protocol prescribed. Future healthcare disclosure advised. Repeat screening planned. Wound infection safety netting.

Costs marks: No decolonisation. Advising unnecessary isolation. Not advising future disclosure.

Domain 3: Interpersonal Skills (Primary focus)

Scores well: Addressing MRSA fear directly. Reassuring about family contact. Normalising colonisation. Allowing normal daily activities. Not stigmatising.

Costs marks: Reinforcing fear. Advising isolation. Being vague about what colonisation means. Stigmatising.

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 distinguishing colonisation from infection. Candidates who discuss MRSA without making this distinction leave the patient believing he has a serious infection. The word 'colonisation' must be explained in plain language.
  2. Advising unnecessary isolation from family. MRSA colonisation does not require home isolation or avoiding grandchildren. Candidates who suggest avoidance cause unnecessary social restriction and anxiety.
  3. Not providing the decolonisation regimen. Chlorhexidine wash and mupirocin nasal ointment are the standard decolonisation protocol. Candidates who counsel without offering treatment provide incomplete management.

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?
