Longitudinal Observational Study on Quality of Life in Patients with Chronic Wounds Using DLQI and EQ-5D.

: Chronic wounds severely impair patients' quality of life (QoL), impacting physical, emotional, and functional well-being. Understanding the multidimensional effects of treatment is key to implementing effective, patient-centered care strategies. This study aimed to assess changes in QoL among patients with chronic wounds using the Dermatology Life Quality Index (DLQI) and EuroQol-5D (EQ-5D), comparing outcomes across treatment modalities. : A longitudinal observational study was conducted between 2019 and 2024 across three hospitals in the Valencian Community. A total of 278 patients with venous lower-limb ulcers of more than six weeks' duration were included. Quality-of-life assessments were performed at baseline, one-month follow-up, and discharge. Treatments included alginate, foam, moist wound healing (MWH), compression therapy, and negative-pressure wound therapy (NPWT). Statistical analysis involved Friedman's test and repeated-measures ANOVA. : Significant improvements were observed in overall QoL across most treatment modalities. EQ-5D scores progressively increased, while DLQI scores decreased. Pain, embarrassment, and limitations in daily life (e.g., shopping and social activities) showed marked reductions. MWH and foam demonstrated the most favorable impact on QoL, while NPWT showed more modest improvements, possibly due to patient complexity. Notably, the variable "sexuality" remained unchanged (mean = 0.00), possibly due to underreporting or communication barriers. : Chronic wound treatments significantly improve patients' quality of life, particularly in terms of pain and social functioning. The use of combined tools (DLQI and EQ-5D) allows for a more comprehensive understanding of these outcomes. These findings highlight the importance of tailoring wound care to individual needs and addressing psychosocial domains, including sexuality. Community nursing, nutritional support, and long-term follow-up should be incorporated into care plans to optimize results, especially in older adults.
