The Effect of Implementing Bar-Code Medication Administration in an Emergency Department on Medication Administration Errors and Nursing Satisfaction.

INTRODUCTION

Bar-code medication administration has been shown to reduce medication errors in inpatient settings with limited studies on its use in emergency departments. In addition, no studies have evaluated nursing satisfaction with implementing bar-code medication administration in an emergency department. This study was designed to determine the impact of implementing bar-code medication administration in an emergency department on medication errors and nursing satisfaction.

METHODS

This is a before-and-after study, with no control group, of a bar-code medication administration intervention conducted in a community hospital emergency department. Direct observation was used to compare medication error rates before and 3 months after implementing bar-code medication administration. The Medication Administration System-Nurses Assessment of Satisfaction survey was used to assess the impact on nursing satisfaction before and 1 month after bar-code medication administration implementation.

RESULTS

A total of 676 medication administrations were observed in the period before bar-code medication administration implementation and 656 after. The medication administration error rate preimplementation was 2.96% with "wrong dose" errors being the most common. After bar-code medication administration implementation, the medication administration error rate fell to 0.76%, a relative reduction of 74.2% (Fisher exact P < 0.01). The average (SD) Medication Administration System-Nurses Assessment of Satisfaction score preimplementation was 2.60 (0.75) and improved to 2.29 (0.66) (t = 2.00, P = 0.05) 1 month post implementation.

DISCUSSION

Implementing bar-code medication administration in a community emergency department was associated with a decrease in medication administration errors and an improvement in Medication Administration System-Nurses Assessment of Satisfaction scores. The results of this study suggest a benefit of bar-code medication administration in reducing medication administration errors and improved nursing satisfaction in the emergency department.
