Time trend of injection drug errors before and after implementation of bar-code verification system

Area of Science:

• Health Informatics
• Patient Safety
• Clinical Pharmacy

Background:

• Medication errors pose a significant risk in clinical practice.
• Bar-code technology offers potential for patient and medication verification.
• Improving medication safety is a key healthcare objective.

Purpose of the Study:

• To evaluate the impact of bar-code verification systems on medication errors.
• To compare error rates before and after system implementation.
• To identify specific types of medication errors affected by bar-code technology.

Main Methods:

• Retrospective analysis of electronic medical error reports.
• Comparison of reported medication errors for injected drugs.
• Assessment of errors related to wrong patient and wrong drug administration before and after bar-code system implementation.

Main Results:

• A total of 2867 error reports were analyzed.
• Significant reduction in wrong patient errors (17.4/year vs. 4.5/year, p<0.05).
• No significant decrease in wrong drug errors (24.2/year vs. 20.3/year); drug preparation identified as the source.

Conclusions:

• Bar-code medication administration effectively prevents wrong patient errors.
• Current bar-code systems have limitations in preventing errors during drug preparation.
• Further interventions are needed to address medication errors originating from drug preparation processes.
