Quality of life healing in patints with venous ulcers of etiology: Validation of Charing Cross Venous Ulcer Questionnaire, Spanish version (CCVUQ-e) and the Pressure Ulcer Scale for Healing, Spanish version (PUSH-e). Preliminary results. Gerokomos [online]. 2011, vol.22, n.3, pp.131-136. ISSN 1134-928X. http://dx.doi.org/10.4321/S1134-928X2011000300008.
Introduction: in Spain, there is no specific measurement instruments for Health Related Quality of Life (HRQOL) and to measuring progress towards healing in patients with chronic wounds that have been validated by research. Having these tools will help the decision-making and improve the quality of care to these patients. Thus, the objectives of this study are: to validate and establish the psychometric properties in Spanish, for "Charing Cross Venous Ulcer Questionnaire (CCVUQ-e)" to measure HRQOL in patients with venous ulcers (UV) and to validate and establish Clinical-metric properties, in Spanish, for "Pressure Ulcer Scale for Healing (PUSH-e)" in the same sample. And, to establish what is the HRQOL of patients in the study sample. Methods: prospective validation of instruments, with a repeated measures model. A estimated sample of 105 patients were selected according to international standard for validating questionnaires. Procedure: for a period of 6 weeks, patients were studied every 2 weeks, collecting variables related to demography, status of disease, ulcers, HRQOL data through the questionnaire CCVUQ-e and SF-12 V2, treatments and healing data trough PUSH-e. Analysis: calculation of psychometric indicators and metrics for measuring clinical validity, reliability and sensitivity to change of such instruments. Descriptive statistics of the variables studied. Comparisons of outcome variables. Results: preliminary results of the study with data from 27 patients with UV. The sample contains all the characteristics of patients with UV. Preliminarily, the CCUVQ-e shows good internal consistency (Cronbach alpha > 0.80). The correlation between CCVUQ-e and PUSH-e at baseline was r = 0.49 (P < 0.001) and at the end of the study was r = 0.64 (p = 0.006). Sensitivity to change of instruments, as with repeated measures model, is statistically significant (p < 0.001). Conclusions: preliminary results show, in both instruments, good psychometric and clinical metrics properties to measure HRQOL and evolution of the wound towards healing. As lesions improve also HRQOL improves.
