Counselling a family after a neonatal morphine error — OSCE

Station brief (8–10 minutes)

A 7-day-old term neonate became briefly apnoeic after a weight-based morphine infusion was prescribed from an adult chart rather than the paediatric formulary. The nurse stopped the infusion, naloxone was given, and the baby has recovered. You are the registrar. The parent is at the bedside. Disclose what happened, explain why a 'standard' dose produced toxicity in this baby, and describe the prevention plan. Do not invent local statutory wording or compensation detail. [1] [5]

Tasks for the candidate

1. Confirm the baby is now safe and monitored before the conversation begins. [1]
2. Disclose the error honestly in plain language: what happened, what it meant for the baby, and why the dose was too much for a neonate. [5]
3. Explain the developmental pharmacology without jargon: a baby clears some medicines more slowly because the liver and kidney are still maturing. [4]
4. Avoid blame language; frame the event as a system failure and describe specific strong prevention actions. [9]
5. Offer follow-up, a named contact, and recognition of the parent's right to ask questions. [9]

Expected performance

Must hit. Confirms the baby is safe before speaking; uses plain, honest language to say a medication error occurred and the baby was given too much morphine briefly; explains the baby received naloxone and is recovering; explains in plain language that a baby's liver and kidney are still maturing, so a dose that is fine for an adult was too much for a newborn; names a clear plan to investigate and prevent recurrence; avoids blaming an individual; offers follow-up and a named contact. [1] [5]

Merit. Names the developmental pharmacology mechanism in plain language — higher body water, low protein binding, immature blood-brain barrier, slow clearance — without jargon; describes concrete strong actions — a paediatric-formulary order set, removal of adult morphine charts from paediatric areas, and an independent double-check of high-risk infusions; acknowledges the distress of staff as well as the family; invites questions and checks the parent's understanding. [4] [9]

Fail. Minimises or conceals the error; blames the nurse or the registrar by name; uses technical language the parent cannot follow; offers no specific prevention plan; leaves the family without a contact or follow-up; becomes defensive or evasive; fails to confirm the baby is safe before talking. [1] [5]

Sample candidate structure

"I want to be honest with you about what happened. While [baby] was receiving a pain medicine called morphine through a drip, the dose was taken from an adult chart rather than the baby chart, and that meant the baby received more than their body could handle at this age. That made [baby] briefly slow their breathing. The nurse noticed straight away, stopped the drip, and we gave a medicine that reverses the effect, so [baby] is breathing normally again now. Babies are not small adults — their liver and kidney are still maturing, and their bodies hold more water, so a dose that is fine for a grown-up was too much for a newborn. This should not have happened, and I am very sorry. We are keeping a close eye on [baby], and we will investigate exactly how the adult chart came to be used here so we can stop it happening again — for example, by making sure only the paediatric chart is used in this area, and by having two nurses check these medicines independently. I will be your point of contact, and please ask me anything." [1] [5] [9]

Marking domains

• Patient safety first — confirms baby is safe and monitored before speaking. [1]
• Honest open disclosure — names the error, the consequence and the apology in plain language.
• Developmental pharmacology in plain language — explains why the dose was too much for a neonate without jargon.
• System framing — describes strong prevention actions rather than blaming an individual.
• Family-centred communication — offers a named contact, follow-up, and invites questions.
