Label Design Affects Medication Safety in an Operating Room Crisis: A Controlled Simulation Study.

Area of Science:

• Anesthesiology
• Patient Safety
• Human Factors Engineering

Background:

• Medication errors are a significant concern in clinical settings.
• Label design is a contributing factor to medication errors.
• High-stress environments exacerbate the risk of errors.

Purpose of the Study:

• To quantify the impact of medication label design on patient safety.
• To evaluate label effectiveness in a realistic, high-stress clinical simulation.
• To assess if redesigned labels reduce medication selection errors.

Main Methods:

• Ninety-six anesthesia trainees participated in a simulated operating room scenario.
• Participants were randomized to either redesigned or current medication label conditions.
• A simulated vascular injury required administration of hetastarch, with lidocaine present as a potential error.

Main Results:

• Correct selection of hetastarch was significantly higher with redesigned labels (63%) compared to current labels (40%).
• Redesigned labels improved the odds of correct medication selection by 2.61.
• No significant difference was found in detecting lidocaine once incorrectly selected.

Conclusions:

• Redesigned medication labels enhance medication safety by improving correct drug selection.
• This intervention can prevent potentially catastrophic medication errors in critical care settings.
• Optimizing label design is a crucial strategy for reducing medication errors.
