Medication safety and error prevention in children — formative SAQs

SAQ 1 — Immediate response and paediatric vulnerability (10 marks)

A six-month-old infant becomes apnoeic on the ward shortly after an opioid infusion is started. The nurse stops the pump. The baby is dusky but has a pulse. The order reads for a weight-based dose, but the pump was set ten times too fast. ^{[1] [8]}

Questions

1. Define medication error, adverse drug event and near miss. (3 marks) ^[1]
2. Outline your immediate clinical and safety actions in order. (4 marks) ^[13]
3. Explain why children are uniquely vulnerable to medication errors. (3 marks) ^[1]

Model answer

Definitions (3). A medication error is any preventable event that may cause inappropriate medication use or harm while the drug is in the clinician's or carer's control. An adverse drug event is actual harm from a medication. A near miss is an error caught before reaching the child. ^[1]

Immediate actions (4). Rescue the airway, breathing and circulation; give naloxone and call for senior help; keep the pump stopped and preserve the settings and syringe; isolate the order and check other children on the same protocol; document facts; tell the family an unexpected event occurred and care is focused on safety; report in the incident system. ^{[13] [1]}

Paediatric vulnerability (3). Dosing is weight-based in mg per kg, so one adult dose fragments into many paediatric possibilities and a misplaced decimal becomes a tenfold error. Neonates and infants have immature hepatic and renal function, narrowing the therapeutic window. Off-label and unlicensed use removes the safety net of an established reference dose. ^{[1] [8]}
