Summary
The Intel® RealSense™ D415/Wound Measure stereophotogrammetry system shows strong agreement for assessing paediatric burn wound area. This technology may enhance clinical burn assessment, despite challenges with contoured surfaces.
Area of Science:
- Medical Imaging
- Biomedical Engineering
- Paediatric Burn Care
Background:
- Stereophotogrammetry (SPG) offers objective burn wound area measurement compared to traditional methods.
- Formal evaluation of the Intel® RealSense™ D415/Wound Measure SPG system in paediatric populations is lacking.
Purpose of the Study:
- To conduct a pilot study comparing the Intel® RealSense™ D415/Wound Measure SPG system with a validated system for paediatric burn assessment.
- To evaluate the agreement between the two SPG systems and among independent raters for wound measurements.
Main Methods:
- A comparative pilot study using the Intel® RealSense™ D415/Wound Measure and LifeVizII®/DermaPix® SPG systems.
- Three independent raters measured wound area and perimeter for 25 acute burns in 13 paediatric patients.
- Intra-class correlation coefficient (ICC) was used to assess agreement between systems and raters.
Main Results:
- Strong agreement (ICC=0.757) was found between the Intel® RealSense™ D415/Wound Measure and LifeVizII®/DermaPix® systems for burn wound area.
- Excellent inter-rater reliability was observed within each SPG system.
- The study included 25 burns from 13 paediatric patients (median age 2 years) with a median TBSA-B of 9%.
Conclusions:
- The Intel® RealSense™ D415/Wound Measure system demonstrates potential as a valuable tool for paediatric burn wound area assessment.
- Challenges in measuring wounds on highly contoured surfaces persist, similar to other SPG systems.
