Purpose: The purpose of this study was to evaluate the impact of barcode-assisted medication preparation (BCMP) on rates of pharmacist-reported dispensing-related medication errors for unit dose products in an inpatient satellite pharmacy.
Methods: This was a pre-post, quasi-experimental study conducted from December 2018 to March 2019. Data was collected from the electronic health record and through online reporting tools for 31-day baseline and intervention time periods. The primary outcome was pharmacist-reported medication dispensing errors. Secondary outcomes included error classification, medication errors captured by BCMP, staff adherence to BCMP, barcode scanning failures, and staff feedback. Chi-squared tests were used to evaluate pharmacist-reported error rates and error classification, and descriptive statistics were used to evaluate BCMP use compliance, barcode error detection and scanning failures, and staff experience.
Results: A total of 14,512 and 15,492 unit dose medications were dispensed in baseline and intervention periods, respectively. A reduction in the number of pharmacist-reported dispensing errors was observed in the intervention period compared to the baseline period (0.06% versus 0.39%; p < 0.001). Most common error classifications in both periods were incorrect dose (50% versus 30%) and incorrect drug (32.1% versus 50%). Barcode scanning was completed for 82.6% of dispenses in the intervention period, of which 469 (3.7%) errors were detected.
Conclusion: The implementation of BCMP demonstrated a statistically significant reduction in the rate of dispensing-related medication errors (p < 0.001). These results support the use of BCMP in medication dispensing as a method of reducing rates of medication errors.
