Validação no Brasil de Questionário de Qualidade de Vida na Doença Venosa Crônica (Questionário Aberdeen para Veias Varicosas no Brasil/AVVQ-Brasil)

Abstract

Background: There is growing global interest in validated health assessment instruments. In order to use these instruments in different countries, it is necessary to conduct translation, cultural adaptation and validation in the target language. In Brazil, there are few instruments for assessment of the impact of chronic venous disease (CVD) on the quality of life (QoL) of patients. Objective: To validate the AVVQ-Brazil. Method: This was an analytical, observational study to validate the AVVQ questionnaire with 107 individuals with CVD. The version of the AVVQ adapted for Brazilian Portuguese was administered three times. The first two administrations were successive, with a 30-minute interval (interobserver reproducibility) and the third administration took place 7 to 15 days later (intraobserver reproducibility). Internal consistency and validity were also assessed. Results: A total of 107 people took part, 87.9% were female, mean age was 50.1 years ± 14.7; the majority had spent long periods standing up (57.0%) throughout their lives and did not engage in physical exercise (96.3%). Many had not completed primary education (25.2%); were members of economic class C2 (36.4%); and had disease severity class C4 (22.4%) or C6 (23.3%) on the CEAP scale. Interobserver and intraobserver reliability of the AVVQ were excellent. Internal consistency was excellent to moderate for the majority of domains. Spearman correlations showed that total AVVQ score and its Pain and Dysfunction domains were negatively correlated with all SF-36 domains. The Mann-Whitney test showed that patients with CEAP 1, 2 or 3 exhibited differences that were statistically significant from those with CEAP 4, 5 or 6 for total AVVQ scores and for Complications domain scores. Conclusions: The AVVQ has been validated for Brazil and can now be used.

Quality of life in chronic venous patients who do or do not wear compressive stockings

“…C1 -telangiectasies or reticular veins, C2 -varicose veins, C3 -edema, C4 for skin conditions such as hyperpigmentation and lipodermatosclerosis, C5 -healed venous ulcer, and C6 -active venous ulcer. 9 Individuals were excluded if they also presented with any of the following conditions: arterial or lymphatic abnormalities; diabetes; hypertension; neuropathy; erysipelas, lymphangitis, acute deep vein thrombosis, ulcer of non-venous origin, psychiatric disorders and/or dementia (physician-diagnosed), as were individuals over the age of 60 with cognitive abnormalities, according to the Mini Mental State Examination (MEEM).…”

“…The result is interpreted along a scale from zero to 100, with zero representing the best score (no evidence of the disease) and 100 the worst (greatest disease severity). 9,11 The study sample comprised 50 patients divided into two groups: 25 patients who wore elastic stockings and 25 who did not wear them, all distributed from CEAP grades C1 to C4.…”

Ultrasound-guided foam sclerotherapy for severe chronic venous insufficiency

“…QL of patients with CVI is altered by physical aspect, pain, functional impairment and mobility deficit 31,32 . Specific questionnaires for CVI QL evaluation are validated in English and are difficult to use in other languages, since they must be translated and validated [33][34][35] . Charing Cross and Aberdeen question forms are translated and validated in Portuguese 36,37 .…”

Análise de concordância em estudos clínicos e experimentais

“…[11][12][13][14] There are a number of different algorithms for calculating ICCs to assess correlation and agreement. However, for the purposes of this text, it is the algorithms for complete agreement that matter.…”
