Analysis of Layperson Tourniquet Application Using a Novel Color-Coded Device

Area of Science:

• Emergency Medicine
• Trauma Care
• Public Health Interventions

Background:

• Layperson application of tourniquets is crucial in pre-hospital trauma care.
• Standard tourniquets can be challenging for untrained individuals to apply correctly.
• Optimizing tourniquet design for public use may improve outcomes.

Purpose of the Study:

• To evaluate if a color-coded tourniquet enhances successful application by laypeople compared to standard black tourniquets.
• To assess factors influencing layperson tourniquet application success and willingness to use.

Main Methods:

• A randomized controlled study involving 157 layperson volunteers.
• Participants applied tourniquets to a mannequin leg with just-in-time (JiT) instructions.
• Comparison between color-coded tourniquets and standard black Combat Application Tourniquets (C-A-T).

Main Results:

• Successful tourniquet application rates were 51.38% with color-coded devices and 44.71% with black devices (P=0.404).
• Participant willingness to use a tourniquet increased significantly from 40.8% to 80.3% post-study (P<0.05).
• Demographic factors did not impact application success.

Conclusions:

• The color-coded tourniquet did not demonstrate a statistically significant improvement in application success rates.
• Laypeople can successfully apply tourniquets approximately half the time with JiT instructions.
• Findings support the potential of laypeople as immediate responders in trauma situations, emphasizing the need to enhance application proficiency.
