mHealth App for Pressure Ulcer Wound Assessment in Patients With Spinal Cord Injury: Clinical Validation Study

摘要: Background Clinical evaluation of a pressure ulcer is based on quantitative and qualitative evaluation. In clinical practice, acetate tracing the standard technique used to measure wound surface area; however, it difficult use in daily practice (because material availability, data storage issues, time needed calculate area). Planimetry techniques developed with mobile health (mHealth) apps can be overcome these difficulties. Objective The goal this study was evaluate metrological properties free-access mHealth app, called imitoMeasure, assess ulcers. Methods This noninterventional, validation study. We included patients spinal cord injury presenting ulcer, regardless its stage or location. performed measurements ruler, we using transparent dressing measurement grid. Wound via app conducted twice by main investigator also coinvestigator determine validity, intrarater reproducibility, interrater reproducibility. Bland-Altman plots intraclass correlation coefficients were compute minimal detectable change percentage. Results Overall, 61 different ulcers included. reproducibility vs (considered method reference) good, 0.97 (95% CI 0.93-0.99), 0.99 0.98-0.99), 0.98 0.96-0.99), respectively, percentages between 17% 35%. Conclusions imitoMeasure had good validity It could an alternative assessment methods. Further studies larger more diverse wounds are needed.
