Adaptación y evaluación inicial del Charing Cross Venous Ulcer Questionnaire en pacientes con úlceras venosas crónicas en Uruguay

Background: Chronic venous ulcers (CVU) represent a frequent condition, with difficult therapeutic approaches, that impact on patients’ quality of life, and generate an economic burden to patients and health systems. Aim: To perform the cultural adaptation and initial evaluation of the Charing Cross Venous Ulcer Questionnaire (CCVUQ) for Uruguay, and to study the health-related quality of life (HRQL) of patients with CVU. Material and methods: The translated and culturally adapted version of the CCVUQ was applied to a convenience sample of 50 patients. In addition, the PROMIS Global Health Survey was included in the assessment. Results: Both questionnaires showed good internal consistency (Cronbach alfa u003e 0.70). A statistically significant association was observed between the CCVUQ total scores, its subscales and both dimensions of the PROMIS: Global Physical (GPH) and Global Mental Health (GMH) (rho ?0.40). The CCVUQ mean score was 54.9 ± 42 points while GPH and GMH mean scores were 37.9 ± 29 points, and 43.1 ± 35.1points respectively. Simple linear regression showed that patients with higher income reported better emotional well-being, while in younger patients, ulcers had a higher impact on Emotional Status and Cosmetics. Conclusions: The translated and adapted version of the CCVUQ was easy to comprehend and apply, showing good psychometric properties. When used in association with the PROMIS Global Health Measure it provides complementary information. HRQL was severely affected in the study sample.
