This document discusses improving drug calculation performance for paramedics working in emergency services. It notes that while technology has reduced errors in hospitals, paramedics in the field have fewer resources to assist with calculations. The purpose is to explore instructional strategies to improve paramedic's drug dosage calculation skills. The rationale is that while many medical errors don't cause harm, errors are still common and risk of adverse outcomes is higher for certain patients. Lessons from other fields need to be applied to emergency medical services education.
