Limitação do VEINES QOL/SYM em discriminar a gravidade da insuficiência venosa crônica / Limitations of VEINES QOL/SYM for discriminating chronic venous insufficiency severity

Resumo Contexto O questionário Venous Insufficiency Epidemiological and Economic Study - Quality of Life/Symptom (VEINES-QOL/Sym) foi desenvolvido para avaliar a qualidade de vida dos indivíduos com insuficiência venosa crônica (IVC), mas ele tem se mostrado pouco sensível em discriminar indivíduos com diferentes gravidades da doença. Objetivos a) Propor uma nova forma de cálculo do escore do VEINES-QOL/Sym e avaliar se esse novo escore é capaz de discriminar a gravidade da doença; b) Avaliar a associação entre o VEINES-QOL/Sym e a gravidade da doença. Métodos Noventa e oito participantes com IVC, de ambos os sexos, idade 60,73 ± 14,11 anos, responderam o questionário VEINES-QOL/Sym, versão português do Brasil. Para o cálculo do novo escore, foi realizada uma transformação dos escores originais para uma escala de 0 a 100. Para verificar a capacidade dos escores do VEINES-QOL/Sym, originais e modificados, em discriminar e classificar corretamente os grupos caracterizados pela classificação clínica, etiológica, anatômica e patofisiológica (CEAP), foi realizada a análise discriminante, sendo considerado significante um alfa de 5%. Resultados Não houve diferença significativa entre os grupos classificados pela CEAP quanto aos escores originais e modificados do VEINES-QOL/Sym. A análise discriminante também não foi capaz de classificar corretamente os grupos CEAP, tanto para os escores originais quanto para os escores modificados do VEINES-QOL/Sym. Além disso, não houve associação entre a classificação CEAP e os escores obtidos pelo questionário. Conclusões O VEINES-QOL/Sym mostrou-se limitado para avaliar qualidade de vida e sintomatologia dos indivíduos com diferentes estágios de IVC.

Abstract Background The Venous Insufficiency Epidemiological and Economic Study - Quality of Life/Symptoms (VEINES-QOL / Sym) questionnaire was developed to evaluate the quality of life of individuals with chronic venous insufficiency (CVI), but it has shown limited sensitivity for discriminating between people with different of disease severity. Objectives a) to propose a new formula for calculating the VEINES-QOL/Sym score and to evaluate whether this new score is capable of discriminating disease severity; and b) to evaluate the association between VEINES-QOL/Sym scores and disease severity. Methods Ninety-eight participants with CVI of both sexes, aged 60.73 ± 14.11 years, answered the Portuguese Brazilian version of the VEINES-QOL/Sym questionnaire. The new score was calculated by transforming the original scores to a 0 to 100 scale. Discriminant analysis was used to test the capability of the original and modified VEINES-QOL/Sym scores to discriminate between and correctly classify groups characterized by the clinical, etiological, anatomical and pathophysiological classification (CEAP). Alpha of 5% was defined as the cutoff for significance. Results There were no significant differences between CEAP groups in terms of the original or modified VEINES-QOL/Sym scores. Discriminant analysis was also unable to correctly classify CEAP groups, using either original or modified scores. Furthermore, there were no associations between CEAP classifications and scores obtained using the questionnaire. Conclusions The VEINES-QOL/Sym proved to have limitations for assessment of the quality of life and symptomatology of people with CVI at different stages.

Limitations of VEINES QOL/SYM for discriminating chronic venous insufficiency severity.

BACKGROUND: The Venous Insufficiency Epidemiological and Economic Study - Quality of Life/Symptoms (VEINES-QOL / Sym) questionnaire was developed to evaluate the quality of life of individuals with chronic venous insufficiency (CVI), but it has shown limited sensitivity for discriminating between people with different of disease severity.

Home-Based Cardiac Rehabilitation in Brazil's Public Health Care: Protocol for a Randomized Controlled Trial.

BACKGROUND: Coronary artery disease (CAD) is among the main causes of hospitalization and death worldwide, therefore, the implementation of programs to reduce its impact is necessary. Supervised cardiac rehabilitation has been shown to have positive effects on CAD control. However, there are barriers to patient participation in the traditional, face-to-face cardiac rehabilitation programs, mainly in low-resource environments. OBJECTIVE: This study aimed to verify patient compliance to a home-based cardiac rehabilitation program, which includes unsupervised health education and physical exercises, guided by telephone. Moreover, we compare this new method to the traditional supervised cardiac rehabilitation offered in most hospital centers. METHODS: We present here a two-arm, single-blinded, and randomized controlled design protocol, which compares the traditional cardiac rehabilitation (CenterRehab) with the home-based cardiac rehabilitation (Home-Based) in 72 patients affected by CAD. The primary outcome is the compliance to the cardiac rehabilitation sessions. The secondary outcomes (to evaluate effectiveness) include measurable variables such as functional capacity, CAD risk factors (blood pressure, waist circumference, glycemic, cholesterol levels, depressive symptoms, and the level of physical activity), the patient's quality of life, the disease knowledge, and the morbidity rate. Parameters such as the program cost and the usability will also be evaluated. The programs will last 12 weeks, with a total of 60 rehabilitation and 6 educational sessions. Patients of the CenterRehab program will participate in 24 supervised sessions and 36 home sessions, while the patients of the Home-Based program will participate in 2 supervised sessions and 58 home sessions, guided by telephone. After the 12-week period all participants will be recommended to continue practicing physical exercises at home or at a community center, and they will be invited for re-evaluation after 3 months. The outcomes will be evaluated at baseline, and after 3 and 6 months. RESULTS: Participants are currently being recruited for the trial. Data collection is anticipated to be completed by October 2019. CONCLUSIONS: This is the first study in Brazil comparing the traditional cardiac rehabilitation approach with a novel, home-based protocol that uses an accessible and low-cost technology. If positive results are obtained, the study will contribute to establish a new and viable model of cardiac rehabilitation.
