Comparative analysis of accuracy and time of calculation of wound surface area using mobile applications

Aim – to carry out a comparative assessment of the accuracy and time of calculating the area of the wound surface using mobile applications.

Material and methods. Wound areas were measured using mobile applications +WoundDesk, ImitoWound and V2F in four blocks of the study: schematic 2D image of soft tissue wounds (block I), volumetric (3D) models of wounds in fractures of the shoulder and leg (block II), experimental wounds in laboratory animals (block III) and assessment of combined wound defects upper and lower jaws in patients (IV block). In the first block, four groups were identified: the 1st group was measured by the area of schematic wounds on a flat surface; in the 2nd, 3rd and 4th groups, by the area of schematic wounds painted on cylindrical surfaces with a diameter of 7, 10 and 20 cm, imitating the surfaces of the forearm, shoulder and head, respectively.

Results. In block I, there is a direct relationship between the curvature of the examined wound surface and the accuracy of determining its area. In the second block, the measurements obtained using the ImitoWound mobile application turned out to be the most accurate, 96.22±3.41% and 97.80±2.37%. In the III block of the study conducted on laboratory rats of the Wistar line, the average deviation when using +WoundDesk was 90.84±7.51%, V2F – 88.96±9.52%, ImitoWound – 92.51±2.54%. In the IV block of the study, when analyzing the accuracy of determining the area of defects of superficial soft tissues in patients with facial defects, the ImitoWound mobile application and the Autoplan complex showed similar results.

Conclusion. Most wounds encountered in medical practice have a complex configuration that changes during treatment, changing from one form to another, which calls into question the expediency of using the presented mobile applications as the main method of conducting planimetric studies in medicine.
