Tackling medication errors: how a systems approach improves patient safety.

Area of Science:

• Healthcare Quality and Safety
• Pharmacovigilance
• Health Systems Research

Background:

• Medication errors are a significant cause of preventable patient harm, affecting roughly 1 in 30 individuals.
• A substantial percentage of medication errors lead to severe adverse outcomes, necessitating urgent intervention.

Purpose of the Study:

• To propose sustainable strategies for reducing medication errors in Europe.
• To employ a systems approach to identify and address the root causes of medication errors.

Main Methods:

• Analysis of 89 anonymised medication error reports and expert practical data.
• Classification of root causes into system-level and individual errors.
• Literature review of PubMed and Embase to identify standards and gaps in medication safety.

Main Results:

• Governance deficiencies and inconsistent legal standard implementation are key contributors to medication errors.
• Prevalent system-level issues include inadequate oversight, understaffing, and poor technical infrastructure.
• Individual errors, often due to cognitive lapses, were also identified, alongside variability in safety practices.

Conclusions:

• Robust governance, comprehensive policies, and enhanced safety cultures are crucial for preventing medication errors.
• Automation and improved human-machine interfaces can mitigate active failures and boost system reliability.
• A systems-thinking approach, strengthened legislation, and better resource allocation are vital for reducing medication errors and enhancing patient safety.
