A randomized controlled trial to examine the effect of the Pediatric Opioid Analgesia Self-Instruction System (PedOASIS) tool on pediatric hematology/oncology trainee education.

PHO fellows exposed to the tool had improved scores on validated knowledge questions and greater comfort using opioids for pain management compared to controls. We therefore suggest that PedOASIS warrants further evaluation as a potential tool for PHO fellows.
