Explain a child's pneumonia and its home treatment to a worried parent — OSCE

Candidate instructions

You are the paediatric registrar. A 4-year-old boy with non-severe community-acquired pneumonia has been assessed: he is alert, feeding, saturating well and has only mildly increased work of breathing, and you have decided he can be treated at home with oral antibiotics. His father has ten minutes with you. He wants to understand, in plain language: (1) what pneumonia is; (2) why his son is going home on tablets rather than being admitted for a drip; (3) why there is no chest X-ray; and (4) exactly what to watch for and when to come back. Explain with empathy, check understanding, and agree a clear plan. [1]

Encounter

Father: "Pneumonia sounds really serious. What actually is it?" [2]

Registrar: "It is a worrying word, so let me explain it simply. Pneumonia is a chest infection where the tiny air pockets deep in the lung, which normally fill with air, get filled instead with fluid and infection. That is what makes him cough, run a fever and breathe faster. In a child like your son, who is alert, drinking and getting enough oxygen, it is usually a mild infection that gets better well with antibiotic medicine." [2] [1]

Father: "Then why not keep him in and give him a drip? Wouldn't that be stronger?" [4]

Registrar: "That is a really natural thing to want, but a drip would not actually help him more. Careful studies show that for a child who is well enough to swallow and keep medicine down, antibiotics by mouth work just as well as the same antibiotics through a drip. Keeping him home, in his own bed and eating normally, is genuinely better for him than a hospital stay he does not need — and we only use a drip when a child is much sicker or cannot keep medicine down." [4] [1]

Father: "Shouldn't he at least have a chest X-ray to be sure?" [3]

Registrar: "It feels like an X-ray would add certainty, but in a child who is this well it does not change what we do, and a study that gave some children an X-ray and others none found it made no difference to how they got better. An X-ray also cannot tell us whether it is a virus or a bacterium. We keep X-rays for children who are much more unwell or not improving, so we avoid unnecessary radiation for your son." [3] [2]

Father: "Will he get worse before he gets better?" [1]

Registrar: "He may take a day or two to turn the corner, and that is normal. With the right antibiotic most children start improving within about two days, and his fever should settle. If instead his fever keeps climbing past a couple of days, or his breathing gets harder, that tells us to look again — that is exactly what I want you to watch for." [1] [2]

Father: "So when do I need to bring him back?" [2]

Registrar: "Here is the clear plan. Come back urgently — call an ambulance if needed — if his breathing looks much harder or faster, with the skin sucking in around the ribs or neck; if he goes pale or blue, or has any pauses in breathing; if he will not drink or has far fewer wet nappies; if he becomes floppy, very drowsy or hard to wake; or if his fever is still high after two days of the antibiotic. And trust your instinct — if you are worried, bring him in. Shall I write these down for you?" [2] [1]

Father: "Yes, please. That makes it much clearer." [1]

Registrar: "I will give you a written fact sheet with those warning signs, the antibiotic instructions and our number, and I will arrange a review in about two days. To check I have explained it well — can you tell me the main things that would make you bring him straight back?" [1]

Examiner debrief

A strong candidate explains pneumonia in plain language (a chest infection filling the air sacs), justifies oral rather than intravenous therapy and home rather than admission with the evidence rather than dismissing the father's worry, explains why a chest radiograph is not needed in a well child while acknowledging the instinct behind the request, warns that improvement may take a day or two and frames persistent fever as a review trigger, and gives concrete, specific return advice focused on breathing, feeding, colour and fever. They check understanding with teach-back and provide written information and a review plan. Pitfalls include admitting or cannulating to satisfy the parent, ordering an unnecessary chest radiograph, and vague safety-netting such as "come back if worse". [1] [2]
