A pilot study comparing two burn wound stereophotogrammetry systems in a paediatric population

Background: Stereophotogrammetry (SPG) provides a more objective measurement of burn wound area than traditional clinical assessments. The recently developed Intel (R) RealSenseTM D415/Wound Measure SPG system has yet to undergo formal evaluation in a paediatric population. Methods: A pilot study comparing the Intel (R) RealSenseTM D415/Wound Measure to the previously validated LifeVizII (R)/DermaPix (R) SPG system, for burn assessment was conducted at a tertiary paediatric burn centre. Both systems were used to photograph and analyse the same acute wounds for each patient. Three independent raters measured wound area and perimeter. Level of agreement between systems and raters was estimated by calculating the intra-class correlation coefficient. Results: Wound area measurements were completed in both systems for 25 burns from 13 patients (median age, 2 years). The participants were mainly female (n = 9), with a median TBSA-B of 9% (IQR 3-20%). There was strong agreement between the systems 0.757 (95% CI 0.521, 0.885, p < 0.001). Within each SPG system, there was excellent inter-rater reliability. Conclusion: The Intel (R) RealSenseTM D415/Wound Measure system may be a viable addition to the clinician's toolkit in the assessment of paediatric burn wound area. As with other SPG systems, there were significant challenges measuring wounds to highly contoured surfaces. (c) 2021 Elsevier Ltd and ISBI. All rights reserved.
