Validity And Reliability of a Smartphone Application in Measuring Surface Area of Lower Limb Chronic Wounds
Background: As the population ages, chronic wounds also raised, creating a load on the health system. Accurate documentation and continuous measurement of wounds have become critical. Aim of the study: It was to determine the validity and reliability (VAR) of a smartphone application in measuring the surface area of lower limb chronic wounds. Patients and Methods: A study of61 patients (46 males and 15 females) with lower limb chronic wounds, aged from 40 to 70 years were selected from Cairo University Hospitals from March 2022 to August 2022. Patients were assessed by the manual planimetry method and a smartphone application (Imito AG, Switzerland). Wound evaluation using the Imito-measure application was performed twice by the principal investigator and by a co-investigator to test Inter-rater reliability (Inter-RR), intra-rater reliability (Intra-RR), and validity. Concurrent validity was investigated by determining the correlation between a smartphone application and the metric graph sheet by Pearson Product Moment Correlation Coefficient. Intra-RR and inter-RR were expressed in Intra-class Correlation Coefficients (ICCs). Results: The validity, intra-RR, and inter-RR of the Imito-measure application were excellent with a strong positive significant correlation (r = 0.998, p = 0.001), ICC was 0.999, with 95% CI 0.998-0.999 and standard of measurement (SEM) of 1.83; ICC for measurement wound surface area was 0.999, with 95% CI 0.998-0.999 and SEM of 1.85, respectively. Conclusion: The Imito-measure application showed excellent VAR for wound measurement, and it could be a selection to be used as an assessment tool in clinical practice.
