Objectives: To compare the evolution of Quality of Life (QoL) between individuals whose Venous Leg Ulcers (VLUs) healed and those whose ulcers did not heal in a specialized chronic wound care service, and to identify the most impacted QoL aspects after one year of treatment. Method: This was a longitudinal, observational, quasi-experimental study involving patients with VLUs. A convenience sample of individuals was followed for at least one year of treatment with either compression therapy or conventional care. QoL was measured using the Medical Outcomes Short-Form Health Survey (SF-36) and the Charing Cross Venous Ulcer Questionnaire (CCVUQ). Participants were categorized into a Healed Group (HG) and a Non-Healed Group (NHG). Results: A total of 103 individuals completed the study, of whom 43 (43.7%) achieved ulcer healing. Binary logistic regression analysis indicated that VLU healing was a significant predictor, especially in the SF-36 domains of Role Physical (R²=0.53, p<0.001, OR=1.06 [1.04–1.08]), Physical Functioning (R²=0.36, p<0.001, OR=1.06 [1.02–1.04]), Pain (R²=0.40, p<0.001, OR=1.05 [1.03–1.07]), and Role Emotional (R²=0.35, p<0.001, OR=1.02 [1.01–1.03]). The CCVUQ assessment showed consistent results across all domains, with Domestic Activities (R²=0.67, p<0.001, OR=1.08 [1.05–1.11]) and Cosmesis (R²=0.66, p<0.001, OR=1.09 [1.05–1.12]) being the most impacted. Conclusion: VLU healing was a key predictor of improved QoL, particularly in physical, emotional, functional, and pain-related aspects. The use of multiple QoL instruments provided a complementary perspective, enhancing the understanding of patient outcomes.
