Abstract
PURPOSE: To determine the effects of a resident physician educational program in a pediatric emergency department (ED) on pharmacy interventions and medication errors, particularly dose adjustments, order clarifications, and adverse drug events (ADE). METHODS: The ED pharmacist recorded all interventions and medication errors on weekdays from 3 to 11 pm during a 9-month period, consisting of a preobservational (Quarter 1), observational (Quarter 2), and interventional (Quarter 3) phases. Program implementation occurred in Quarter 3, with an initial 3-hour lecture during the ED orientation, followed by daily patient case discussions. Weekly interventions and errors were analyzed using statistical process control u-chart analyses. Chi-square analyses of independence were also performed. Resident and ED staff feedback on the program was obtained through anonymous internet-based surveys. RESULTS: A total of 3507 interventions were recorded during the 9-month period. Chi-square approximation and interval estimation of odds ratio showed a statistically significant decrease between Quarters 1 and 3 in the number of dose adjustments (95% confidence interval [CI], 0.324-0.689) and order clarifications (95% CI, 0.137 to 0.382) after initiation of the program. The decline in ADE, while not as substantial (95% CI, 0.003 to 1.078), still achieved a level of significance (90% CI, 0.006 to 0.674). Survey results were positive toward the program. CONCLUSIONS: The implementation of a resident physician educational program in our pediatric ED significantly decreased the number of medication errors, increased resident physician awareness of the potential for errors, and increased ED pharmacist utilization.
