Explain chronic aspiration and a feeding plan to a parent — OSCE

Candidate instructions

You are the paediatric registrar. A 3-year-old boy with cerebral palsy is recovering from his third pneumonia this year, each in the right lower lung. His mother has ten minutes with you. She wants to understand, in plain language: (1) why this keeps happening when he does not cough on his feeds; (2) what a swallow study will involve; and (3) whether he will need a feeding tube. Explain with empathy, check understanding, and agree a clear plan. [1]

Encounter

Mother: "Why does he keep getting chest infections? He doesn't even cough when he eats." [1]

Registrar: "That is such an important question, and it is a really common worry. In children like your son, tiny amounts of food, drink or even his own saliva can slip into the breathing tubes instead of going down to the stomach. Usually a child would cough to protect the lungs, but because of his cerebral palsy his throat is less sensitive, so it can happen quietly — we call it silent aspiration. Over time those small amounts irritate the lungs and cause the repeated infections, always in the same lower part of the lung." [1]

Mother: "So the fact he doesn't cough is actually part of the problem?" [3]

Registrar: "Exactly — and it is why we cannot rely on watching him eat alone. A speech pathologist will watch a feed carefully, but because a quiet swallow can look fine, we usually add a special test to see what is really happening inside." [3] [1]

Mother: "What does that test involve?" [2]

Registrar: "It is called a videofluoroscopic swallow study. We give him different textures — thin drinks, thickened drinks, purees — mixed with a harmless contrast, and take a moving X-ray while he swallows. It shows us exactly which textures are safe and which slip toward his airway, so we can tailor his feeds rather than guess. Sometimes we use a small camera through the nose instead. Neither is painful." [2] [1]

Mother: "Will he need a feeding tube? That frightens me." [1]

Registrar: "I understand — most parents feel that way, so let us take it step by step. Often we can make eating safe just by thickening drinks, changing textures, and helping him sit upright and take his time. We only consider a feeding tube if we cannot make swallowing safe, or if he cannot get enough nutrition to grow, and even then it can be temporary and he may still enjoy some tastes by mouth. The goal is to protect his lungs and his growth, and we decide it together." [1] [4]

Mother: "That makes it less scary. What else will help his chest?" [4]

Registrar: "Alongside the feeding plan, we will help clear his chest with physiotherapy, treat any chest infection promptly, keep his immunisations up to date, and manage his drooling and any reflux, because those add to the problem. A whole team — chest doctors, ear-nose-and-throat, gut doctors, speech pathology and dietitians — will work with you. To check I have explained things well, could you tell me in your own words why he keeps getting the infections?" [4] [1]

Examiner debrief

A strong candidate explains chronic aspiration and silent aspiration in plain language, links the repeated same-site pneumonias to the unsafe swallow, and justifies the swallow study rather than relying on watching a feed. They address the feeding-tube fear honestly and proportionately, framing it as a step reserved for when swallowing cannot be made safe or nutrition is failing, and they describe the multidisciplinary lung-protection plan. They use empathy and teach-back and avoid false reassurance. Pitfalls include dismissing the mother's observation that he does not cough, promising no tube will ever be needed, and treating the pneumonia without ever addressing the cause. [1] [4]
