This study aims to identify factors associated with the healing process of these wounds and develop a mobile application for wound care that incorporates these factors. A prospective multicentre cohort study was conducted in nine health units in Portugal, involving data collection through a mobile application by nurses from April to October 2022. The study followed 46 patients with 57 wounds for up to 5\u2009weeks, conducting six evaluations. Healing time was the main outcome measure, analysed using the Mann\u2013Whitney test and three Cox regression models to calculate risk ratios. The study sample comprised various wound types, with pressure ulcers being the most common (61.4%), followed by venous leg ulcers (17.5%) and diabetic foot ulcers (8.8%). Factors that were found to impair the wound healing process included chronic kidney disease (<jats:italic>U<\/jats:italic>\u2009=\u200913.50; <jats:italic>p<\/jats:italic>\u2009=\u20090.046), obesity (<jats:italic>U<\/jats:italic>\u2009=\u200918.0; <jats:italic>p<\/jats:italic>\u2009=\u20090.021), non\u2010adherence to treatment (<jats:italic>U<\/jats:italic>\u2009=\u20091.0; <jats:italic>p<\/jats:italic>\u2009=\u20090.029) and interference of the wound with daily routines (<jats:italic>U<\/jats:italic>\u2009=\u200911.0; <jats:italic>p<\/jats:italic>\u2009=\u20090.028). Risk factors for delayed healing over time were identified as bone involvement (RR 3.91; <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), presence of odour (RR 3.36; <jats:italic>p<\/jats:italic>\u2009=\u20090.007), presence of neuropathy (RR 2.49; <jats:italic>p<\/jats:italic>\u2009=\u20090.002), use of anti\u2010inflammatory drugs (RR 2.45; <jats:italic>p<\/jats:italic>\u2009=\u20090.011), stalled wound (RR 2.26; <jats:italic>p<\/jats:italic>\u2009=\u20090.022), greater width (RR 2.03; <jats:italic>p<\/jats:italic>\u2009=\u20090.002), greater depth (RR 1.72; <jats:italic>p<\/jats:italic>\u2009=\u20090.036) and a high score on the healing scale (RR 1.21; <jats:italic>p<\/jats:italic>\u2009=\u20090.001).
