Explain a suspected brain abscess to a worried parent — OSCE

Candidate instructions

You are the paediatric registrar. You have five minutes to speak with Mrs Tan, whose nine-year-old son Aiden was admitted an hour ago with a week of headache and fever and new confusion. His scan shows a brain abscess — a collection of pus in his brain — and the neurosurgeons are preparing him for a small operation to drain it. She is frightened and has a lot of questions. Explain what is happening in plain language, be honest about the seriousness, explain the operation and the antibiotics, and help her understand the recovery and follow-up without overpromising. Answer her questions, check her understanding, and agree a plan with her. [1]

Actor brief (parent — Mrs Tan)

You are frightened and trying to hold it together. You took Aiden to the GP twice last week and were told it was sinusitis. Now he is confused and they are talking about an operation on his brain. You want to know: (1) What exactly is a brain abscess and is it life-threatening? (2) What does the operation involve and is it safe? (3) Why does he need antibiotics for weeks, and through a drip? (4) Will he recover fully — will there be brain damage? (5) Could this have been found earlier? Push back if the candidate uses jargon or overpromises. You calm a little when you feel heard and given honest, clear information. [3]

Exemplar candidate approach

Open and acknowledge. "Mrs Tan, please sit down. I can see how frightening this is, and I am sorry you have had such a frightening morning. I want to explain clearly what we have found, what we are doing right now, and what the next steps are, and I will answer every question you have. Aiden is in safe hands and we are moving quickly." [1]

Explain the diagnosis in plain language. "A brain abscess is a collection of pus — an infection — that has formed inside the brain, in Aiden's case probably tracked in from the sinus infection he has had. The pus collects in a little pocket and swells, which is what has been causing his headache and the confusion you saw this morning. It is a serious condition, and that is why we are treating it as urgent, but it is one we can treat." [1] [3]

Explain the operation and the antibiotics. "The neurosurgeons are preparing a small operation to drain the pus. They make a tiny hole in the skull and use a fine needle to draw the pus out — this both relieves the pressure on his brain and lets us test the pus to find the exact germ causing it, so we can choose the right antibiotic. The operation is generally safe, and the team do this regularly. After it, he will need antibiotics through a drip for several weeks, because the infection is deep in the brain and we need a long, strong course to clear it completely and stop it coming back." [2]

Address prognosis honestly. "I want to be honest with you. Most children do well with this treatment — the operation and the antibiotics together are very effective — but because it is the brain, we cannot promise a full recovery straight away. Some children have temporary weakness or seizures, and a smaller number have longer-term effects, which is why we will follow him closely with scans and with a developmental check over the months ahead. What I can promise is that we will watch him very carefully and support him and you through every step." [4]

Address the 'found earlier' question with empathy. "I understand why you are asking that, and it is a fair question. Brain abscess can be very hard to spot early, because for the first few days it looks just like an ordinary sinus infection or a virus — the warning signs often come late. I do not think anyone missed something obvious, but I will go through his story with you carefully, and if there is anything to learn from it we will be honest about that too." [3]

Check understanding and agree a plan. "Can I check — what is your main worry right now, and have I explained anything unclearly? Here is what will happen next: the operation today, then a stay in hospital for the antibiotics, scans to track his recovery, and the team looking after the sinus source. I will come and update you after the operation, and you can ask me anything at any time." [2] [4]

Mark scheme (10 marks)

• Empathy and relationship (2): acknowledges fear and guilt, does not dismiss, sits and listens, plain language. [3]
• Explains the diagnosis clearly (2): brain abscess as a collection of pus, the sinus source, the seriousness without frightening unnecessarily. [1]
• Explains the operation and antibiotics accurately (2): aspiration to drain and culture, weeks of intravenous antibiotics and the rationale. [2]
• Honest prognosis without overpromising (2): most do well; some have temporary or longer-term effects; close follow-up promised. [4]
• Checks understanding and agrees a plan (2): invites questions, checks comprehension, sets out next steps and ongoing availability. [2]
