Retrospective Review for Medication Dose Errors in Pediatric Emergency Department Medication Orders That Bypassed Pharmacist Review.

Objective: To identify and evaluate dose errors on medication orders that bypassed pharmacist verification in a pediatric emergency department (PED).

Methods: Descriptive, retrospective study about dose errors in an academic PED over 1 year. A report of automatically verified orders (those that bypassed pharmacist verification) was obtained from the electronic medical record. Potential medication dose errors were defined as those greater than 20% above or below standard dose ranges by age or weight. A retrospective chart review was performed for all identified dose errors. For orders deemed erroneous, additional metrics collected included order time of day and day of week and provider training level.

Results: A total of 46,185 medication orders were placed; 32,928 (71%) bypassed pharmacist review. Altogether, 676 orders (2%) were outside standard dose ranges. Ondansetron represented 569 of the 676 orders; most were doses rounded down to 4 mg and technically qualifying as underdoses, but were attributed to practice variance and not further analyzed. The number of orders deemed potentially erroneous was 107: most were wrong dose (75 overdose and 21 underdose), 5 were wrong patient, and 6 were wrong formulation. Ibuprofen, benzodiazepine, and corticosteroid orders had the most errors. No errors resulted in identifiable harm to the patient: 49 were near misses, and 47 reached the patient with no evident harm.

Conclusions: The overall number of dose errors in autoverified orders was low. Certain medications or ordering modalities may be targeted to enhance patient safety and satisfaction.
