Pediatric patients are at particularly high risk for medication errors. This article describes the STAMP initiative (Safe Treatment and Administration of Medicine in Pediatrics) which aims to reduce pediatric inpatient prescribing and administration errors. The authors summarize the STAMP interventions originally implemented in 2017 and discuss the new interventions implemented during the COVID-19 pandemic (between July 2020 and August 2021), which led to sustained reductions in prescribing errors.
