The University of Tokyo Hospital has revealed that one of its nurses mistakenly gave the wrong medication to a boy in 2015, admitting it "might have had some kind of an impact" leading to his death the day after being given the medicine.
According to the hospital, the nurse was trying to administer the medicine via an infusion to the boy, who was suffering from serious multiple organ failure.
The nurse stopped the process to answer the phone, and when she restarted the infusion she picked up a drug for a different patient by mistake.
