A standardized formulary to reduce pediatric medication dosing errors: a mixed methods study.

Pediatric medication administration in prehospital care is challenging due to the need to obtain an accurate weight and calculate dosing. The Los Angeles County emergency medical services implemented a Medical Control Guideline (MCG) to eliminate the need to calculate the dose of a commonly administered medication. Following implementation of the MCG, dosing errors decreased from 18.5% to 14.1% in pediatric prehospital care.
