Inflicted burns and scalds — branching viva

Opening

Examiner: An eighteen-month-old boy is brought to the emergency department with a scald to both feet and lower legs. The burn stops at a sharp, clear line just above both ankles, there are no splash marks, and the depth is uniform. His mother says he pulled a cup of hot tea over himself while standing at a coffee table. How do you frame this? [1]

Candidate: I am immediately concerned that this is an inflicted immersion scald. The pattern — symmetrical stocking-glove distribution with a sharp upper margin, uniform depth, and no splash marks — is not consistent with a cup-of-tea spill, which would produce an irregular splash with tapering edges and visible splash marks. I would treat the burn and initiate the safeguarding pathway in parallel from this first contact. [1]

Branch 1 — pattern recognition

Examiner: Walk me through the inflicted versus accidental pattern. [1]

Candidate: The Maguire 2008 systematic review is the definitive synthesis. An accidental spill scald produces an irregular splash pattern with tapering, dripping edges, variable depth where the liquid ran off, and splash marks on nearby skin. A forced immersion scald produces a symmetrical stocking-glove or glove distribution with a sharp fluid-level margin, uniform depth because the limb was held still, no splash marks, and often flexure-sparing where the skin was folded against itself. This child has every feature of the immersion pattern and none of the spill pattern. [1]

Examiner (probe): Why is developmental plausibility important here? [1]

Candidate: At eighteen months a child can stand and reach a coffee table, so the story is superficially plausible — but the pattern is not. The developmental check matters most in pre-mobile infants, where any significant burn is inflicted or neglectful until proven otherwise because the infant cannot reach, pull, climb, or turn on a tap. In this toddler, the pattern is the discriminator; in a younger infant, the developmental stage alone would be the red flag. [1]

Branch 2 — the BuRN-Tool and the whole-child exam

Examiner: How do you objectify your suspicion? [2]

Candidate: I apply the BuRN-Tool, the clinical decision rule derived and validated by Kemp and colleagues in 2018. It combines features of the history, the injury pattern, and child or family factors to flag burns with a high probability of maltreatment. It does not replace clinical judgement, but it gives me a defensible, evidence-based basis for escalating concern — which matters when the family is pressing to go home. [2]

Examiner (probe): What else do you look for on examination? [3]

Candidate: A full top-to-toe and head-to-skin examination, because inflicted burns frequently travel with other injuries. The Pawlik 2016 study of children referred for child-abuse burn evaluation found a high rate of co-existent injury — bruises, fractures, older burns. I examine the genitalia, perineum, posterior trunk, and hidden sites explicitly, and I document every finding. A single-system exam of just the burn is a safeguarding error. [3]

Branch 3 — investigations and safeguarding

Examiner: He has no other injuries on exam. What is your investigation plan? [6]

Candidate: I request a skeletal survey, because he is under two and inflicted injury is suspected — the survey looks for occult fractures of different ages that reshape the safeguarding risk, and I would repeat it at around two weeks to capture fractures not visible acutely. I send baseline bloods including coagulation, and I photograph the burn with consent and a measuring ruler in frame. Then I convene a strategy discussion with social care, police, and the safeguarding team to agree further investigation and the safe disposition. [6]

Examiner (probe): What is the mandatory-notification duty? [6]

Candidate: When inflicted injury is suspected, I must notify my designated child-protection lead or social care. The duty is statutory in ANZ, the UK, and North America, and it overrides ordinary confidentiality. The child is admitted to a place of safety — usually the paediatric ward under consultant supervision — and is not discharged home while the safeguarding assessment is incomplete. The strategy discussion coordinates the multi-agency response. [6]

Branch 4 — pathophysiology

Examiner: Explain why the immersion burn looks the way it does. [7]

Candidate: It comes down to temperature, duration, and skin thickness. Water at 60 degrees produces a full-thickness burn in about three seconds, while at 49 degrees it takes about ten minutes. A forced immersion holds the child motionless in hot water, so the entire exposed area receives a uniform sustained exposure — producing a deep burn with a sharp fluid-level margin and no splash marks. A child's skin is considerably thinner than an adult's, so the same exposure produces a deeper burn. The pathophysiology is the diagnostic vocabulary: when you can read the mechanism off the pattern, you can test the history against it. [7]

Branch 5 — prevention and follow-up

Examiner: His mother asks what could have prevented this. What do you say? [9]

Candidate: I explain that the evidence base for prevention is strong. The SafeTea programme — evaluated in the Cowley 2021 process study and the Bennett 2020 feasibility study — is a multimedia campaign to prevent hot-drink scalds in young children and promote correct burn first aid, and it shows that targeted, parent-facing prevention works at the population level. Prevention counselling is part of every burn encounter: hot-drink safety, tap-water thermostat setting, and smoke alarms. But for this child, the immediate priority is the safeguarding plan, not prevention advice to a carer under suspicion. [9]

Examiner (final corner): And if the skeletal survey shows a healing rib fracture? [3]

Candidate: That confirms additional inflicted injury of a different age and raises the safeguarding risk substantially. The child remains in a place of safety, the strategy discussion is reconvened with the new finding, and the multi-agency case conference plans a robust child-protection plan. The burn and the fracture together establish a pattern of repeated inflicted injury, and the long-term plan addresses the child's safety, welfare, and mental health. [3]
