Antibiotic Prescribing Errors in Patients Discharged From the Pediatric Emergency Department.

Abstract

The pediatric emergency department (PED) is an especially high-risk setting for medication errors. Several factors contribute to this risk including the need to provide care to complex patients who are unknown to staff, the frequent use of verbal orders, and the necessity of weight-based dosing. This investigation sought to assess one potentially error-prone event, antibiotic prescriptions written for patients being discharged from the PED, and to characterize the occurrence of medication errors to identify opportunities for improvement. This was a retrospective study of pediatric patients seen at a large academic medical center PED. All prescriptions written for an antibiotic for patients 18 years or younger that were discharged from the PED from 2015 to 2018 were evaluated for errors in directions, indication, dose, quantity, and refills. Because antibiotic dosing can vary based on indications, only disease states with guideline-specific dosing recommendations were evaluated for dosing errors. A total of 11,815 antibiotic prescriptions were analyzed for patients discharged from the PED, and 1986 (16.8%) errors were identified. Of all the prescriptions reviewed, 517 (4.4%) contained an incomplete prescription error. Discharge prescriptions written by off-service physicians were more likely to contain incomplete prescription errors (5.1%) when compared with emergency medicine physicians (3.9%; P = 0.022). A dosing error rate of 18.5% (1469 prescriptions) was identified for the 7930 disease state-specific prescriptions reviewed. Underdosing errors were significantly more common (51.6%) than overdosing errors (29.3%; P < 0.0001). Among the different agents, there was noted to be a significant difference in the antibiotics most commonly involved in dosing errors (P < 0.0001). Additionally, there was also a significant difference in the incidence of dosing errors between different disease states (P < 0.0001). No significant difference was found in the incidence of dosing errors across physician specialties (P = 0.872). We identified 1986 (16.8%) total errors in this analysis of antibiotic prescriptions written on discharge from the PED. Among the disease states evaluated, dosing errors were identified in 18.5% of prescriptions with the most common error being underdosing. Literature evaluating pediatric prescription errors, and specifically antibiotic discharge prescriptions, is quite limited. Further investigation is necessary in this area, and strategies should be developed leveraging technology, enhancing education, and using pharmacy personnel to help reduce antibiotic prescribing errors for patients discharged from the PED.
