Abstract

BackgroundResponsiveness is a measure of an instrument’s ability to reflect in its score the variability that has occurred in a patient’s life as a result of an intervention. The CCVUQ-Br has been validated in Portuguese, but its responsiveness still needs to be tested. When this study has been completed, the CCVUQ-Br will be available for use as an instrument capable of detecting and reflecting in its score the changes that take place in the quality of life of people with venous ulcers.ObjectivesTo evaluate the responsiveness of the CCVUQ-Br.MethodsA longitudinal intervention study was conducted at public and private centers for patients with venous ulcers. The sample comprised people with chronic venous ulcers due to start treatment and the variables analyzed were CCVUQ-Br score and its domain scores, a pain visual analog scale (pain VAS), and the Global Assessment of Change Scale, in addition to CEAP classification, and size of ulcer. The CCVUQ-Br was administered to 51 people about to start treatment who were recruited at random. The CCVUQ-Br was then re-administered 4 weeks after treatment had started.ResultsMean CCVUQ-Br scores reduced from the first to the second administration. The highest mean score at baseline was for the Emotional Status domain, at 63.45, which dropped to 52.00 after 4 weeks. There were also correlations between changes in CCVUQ-Br scores and pain VAS ratings and CEAP class. With regard to the effect size, total CCVUQ-Br score and ulcer size exhibited high sensitivity, while pain VAS and the majority of the CCVUQ-Br domains had moderate sensitivity.ConclusionsThe CCVUQ-Br questionnaire is sensitive in the Brazilian population and exhibited response to change in the sample tested.

Highlights

The importance of studies of the quality of life (QoL) of patients with venous ulcers lies in the fact that chronic ulcers are considered a global epidemic,[1] affecting around 1% of the adult population.[2]
The majority of patients (45.1%) had had an active venous ulcer for more than 1 year, 29.4% were retired because of age, 27.5% were still working, and 25.5% were retired because of illness (Table 1)
This study assessed the Charing Cross Venous Ulcer Questionnaire (CCVUQ)-Br in relation to change over time and these changes were correlated with changes measured by other scales
