AiRDose: Developing and Validating an Augmented Reality Smartphone Application for Weight Estimation and Dosing in...

Area of Science:

• Pediatric emergency medicine
• Medical device technology
• Clinical informatics

Background:

• Inaccurate weight estimation in pediatric emergencies leads to medical errors.
• Current guidelines recommend length-based tools like the Broselow tape.
• The AiRDose app utilizes augmented reality for length-based estimates and critical care recommendations.

Purpose of the Study:

• To compare AiRDose's length estimations with standard tape measures.
• To evaluate AiRDose's estimated weights and medication doses against established methods.

Main Methods:

• A prospective study involving 549 children in two emergency departments.
• Measurements obtained using AiRDose, Broselow tape, and standard tape measure.
• Spearman rank correlation coefficients calculated to assess agreement.

Main Results:

• 99.6% of AiRDose length estimates were within 20% of tape-measure lengths.
• Strong correlations found between AiRDose and standard measurements for length, weight, and medication doses.
• AiRDose demonstrated high accuracy in estimating critical medication doses (epinephrine, lorazepam).

Conclusions:

• AiRDose provides accurate anthropometric estimates and medication dose recommendations.
• The app shows strong correlation with established pediatric emergency care techniques.
• Further research is needed to confirm AiRDose's prehospital feasibility.
