The risks of double checking.

Area of Science:

• Healthcare safety
• Human factors engineering
• Medication administration

Background:

• Double checking medications is a standard procedure for healthcare professionals, especially nurses.
• A study by Armitage (2003) highlighted that this practice can sometimes contribute to medication errors.
• Understanding the underlying causes of these errors is crucial for improving patient safety.

Purpose of the Study:

• To explore the reasons why double checking medications can lead to errors.
• To apply principles from human error theory to medication safety.
• To investigate potential solutions inspired by other high-risk industries, such as aviation.

Main Methods:

• Analysis of medication error reporting data (Armitage 2003).
• Application of human error theories to the context of medication administration.
• Comparative analysis with safety protocols in the aviation industry.

Main Results:

• Double checking, while intended to prevent errors, can introduce new ones due to cognitive biases and system flaws.
• Human error theories provide a framework for understanding the psychological and systemic factors involved.
• The aviation industry's approach to safety management offers potential models for reducing medication errors.

Conclusions:

• Rethinking the reliance on double checking as a sole safety measure is necessary.
• Integrating human error principles can enhance medication safety protocols.
• Adopting strategies from aviation safety may provide innovative solutions to prevent medication errors.
