Preventing medication errors in community pharmacy: root-cause analysis of transcription errors

Area of Science:

• Pharmaceutical Sciences
• Patient Safety Research
• Healthcare Systems Analysis

Background:

• Medication errors pose significant risks to patient well-being.
• Ensuring medication safety is a critical component of pharmaceutical care.
• Understanding community pharmacy workflow vulnerabilities is key to preventing medication errors.

Purpose of the Study:

• To investigate the causes of medication errors in community pharmacies.
• To identify system vulnerabilities contributing to medication incidents.
• To provide a basis for improving patient safety in pharmaceutical care.

Main Methods:

• Data collection on medication errors from 40 randomly selected Danish community pharmacies.
• Analysis of medication error cases that reached patients.
• In-depth root-cause analyses of the most serious medication error incidents by an interdisciplinary team.

Main Results:

• 401 medication error cases reaching patients were analyzed, many with potential clinical significance.
• Transcription errors were the most frequent, with dosage and strength errors being the most serious.
• Identified root causes include handwritten prescriptions, packaging/name similarities, inadequate label checks, and interruptions.

Conclusions:

• A significant number of medication errors in community pharmacies have potential clinical impact.
• Root-cause analysis effectively identifies underlying causes of medication errors.
• Findings provide a foundation for implementing targeted interventions to enhance patient safety.
