Paediatric harmful adverse drug events (PHADE).

This is the first study to quantify harmful adverse drug events in paediatric hospital practice. Our prospective analysis and compilation of harmful medication errors in paediatric hospital practice, reported with denominators of opioid administrations, and patient bed days, is a new standard for comparison in the long-discussed problem of paediatric harmful adverse drug events. By focusing on identified problematic drugs, error types, and contributory factors, we identify opportunities for interventions, error prevention and harm reduction.
