Gregory H, Cantley M, Calhoun C, et al. - Researchers aimed at quantifying and characterizing the medication errors that occur in cases discharged from the emergency department (ED). From 2015 to 2018, they reviewed a total of 115,933 prescriptions and identified a total of 20,498 errors within 19,126 prescriptions. Among all prescriptions provided to patients upon ED discharge, a 16.5% error rate was thus noted that differed among different subcategories of medications. The identified errors involved 4,048 (19.7%) errors related to prescription directions, 6,537 (31.9%) errors in quantity prescribed, and 9,913 (48.4%) errors in prescriptions written with refills. Among different prescriber statuses, significant differences were observed in the proportion of errors when comparing all prescribers. Significantly more errors in quantity and refills were identified in prescriptions written by Non-Emergency Medicine residents, and significantly more errors in directions were observed in prescriptions written by Emergency Medicine residents.
