RESUMO
Objetivo: Descrever o manejo clínico da Doença de Chagas (DC) por profissionais médicos da Atenção Primária à Saúde (APS) de região endêmica. Metodologia: Estudo transversal entre médicos da APS de 23 municípios. A coleta contemplou questões Demográficas, Formação Acadêmica, Características da APS de Atuação, Práticas e Conhecimento Relativos à DC. Conduziram-se análises descritivas de todas as variáveis e bivariadas para os blocos de práticas e conhecimento relativos à DC considerando o tempo de conclusão da graduação. Resultados: Foram incluídos 136 médicos. A maioria mencionou conhecer o Protocolo Clínico e Diretriz Terapêutica da DC, mas não prescreveu o benzonidazol e se sente insegura no manejo do paciente. Na análise bivariada, a variável conhecimento sobre a DC adquirido na graduação mostrou-se associada estatisticamente ao tempo de graduação. Conclusão: Importantes obstáculos ainda persistem no manejo médico ao paciente com DC na APS. A partir desse achado espera-se incentivar a qualificação.
Objective: To describe the clinical management of Chagas Disease (CD) by Primary Health Care (PHC) physicians in an endemic region. Methodology: Cross-sectional study with PHC physicians from 23 municipalities. The collection included questions on Demographics, Academic Background, Characteristics of the APS in Action, Practices and Knowledge Relating to CD. Descriptive analyzes of all variables and bivariates were carried out for the blocks of practices and knowledge related to CD, considering the time of completion of graduation. Results: 136 physicians were included. Most mentioned knowing the CD Clinical Protocol and Therapeutic Guideline, but did not prescribe benznidazole and feel insecure in-patient management. In the bivariate analysis, the variable knowledge about CD acquired during graduation was statistically associated with graduation time. Conclusion: Important obstacles still persist in the medical management of patients with CD in PHC. Based on this finding, it is expected to encourage qualification.
RESUMO
ABSTRACT Numerous tests employed to predict cardiac and functional status are expensive and not widely accessible for a considerable number of patients, particularly those diagnosed with Chagas disease (CD) residing in remote and endemic regions. To date, there is no knowledge of studies that have validated instruments that address functionality in an expanded way, including the biopsychosocial factors in patients with CD. This study aims to evaluate the psychometric properties of the World Health Organization Disability Assessment Schedule (WHODAS 2.0), in its 12-item shortened version (WHODAS-12) when applied to patients with CD. This is a cross-sectional study of a prospective cohort that follows individuals with CD (SaMi-Trop). Data collection took place between October 2019 and March 2020. In the interviews, sociodemographic information, life habits, clinical information, and indicators of disability measured by WHODAS-12 were collected. Descriptive analysis, internal consistency and construct validity of the instrument were performed. A total of 628 patients with CD were interviewed, most were women (69.5%), their mean age was of 57 years, and most declared an average self-perception of health (43.4%). The 12 items of WHODAS-12 were distributed into three factors, which together account for 61% of the variance. The Kaiser-Meyer-Olkin (KMO) index was 0.90, indicating adequacy of the sample for factor analysis. The internal consistency of the global scale showed alpha = 0.87. The percentage of incapacity was 16.05%, indicating mild incapacity for the evaluated patients. WHODAS-12 is a valid and reliable measure to assess the disability of the Brazilian population with CD.
RESUMO
ABSTRACT Background: Chagas disease (ChD) is a neglected tropical disease that is caused by the protozoan parasite Trypanosoma cruzi and can negatively impact quality of life (QoL). This study aimed to assess and compare QoL between individuals with and without ChD. Methods: This cross-sectional study was performed within a concurrent cohort study (REDS). The participants were derived from two blood donation centers: São Paulo capital and Montes Claros, Minas Gerais, Brazil. Participants with ChD were identified in blood donations by serological diagnosis between 2008 and 2010, and those without ChD were donors with negative serology identified during the same period. QoL was assessed using the World Health Organization Quality of Life-BREF questionnaire. Logistic regression was used to compare sociodemographic and clinical characteristics between the groups, and mean, standard deviation, and beta regression were used to compare QoL. Results: In total, 611 individuals participated in the study (328 with ChD and 283 without ChD). Participants with ChD had lower QoL in the physical (p=0.02) and psychological (p<0.01) domains than did individuals without CD. Conclusions: Individuals with ChD had worse QoL perceptions. These results provide a comprehensive understanding of the impact of ChD on individuals' QoL, while also highlighting potential opportunities for improving the care and treatment of those affected.
RESUMO
Abstract Chagas disease (CD) is recognized by the World Health Organization as one of the thirteen most neglected tropical diseases in the world. Self-perceived health is considered a better predictor of mortality than objective measures of health status, and the context in which one lives influences this predictor. This study aimed to evaluate the prevalence and individual and contextual factors associated with poor self-rated health among CD patients from an endemic region in Brazil. It is a multilevel cross-sectional study. The individual data come from a cross-section of a cohort study named SaMi-Trop. Contextual data was collected from publicly accessible institutional information systems and platforms. The dependent variable was self-perceived health. The analysis was performed using multilevel binary logistic regression. The study included 1,513 patients with CD, where 335 (22.1%) had Poor self-rated health. This study revealed the influence of the organization/offer of the Brazilian public health service and of individual characteristics on the self-perceived health of patients with CD.
Resumo A Doença de Chagas (DC) é reconhecida pela Organização Mundial da Saúde como uma das treze doenças tropicais mais negligenciadas do mundo. A autopercepção de saúde é considerada um melhor preditor de mortalidade do que medidas objetivas do estado de saúde, e o contexto em que se vive influencia esse preditor. O objetivo deste estudo foi avaliar a prevalência e os fatores individuais e contextuais associados à pior autopercepção em saúde de pacientes com DC de uma região endêmica do Brasil. É um estudo transversal multinível. Os dados individuais vêm de um corte transversal de um estudo de coorte denominado SaMi-Trop. Os dados contextuais foram coletados a partir de plataformas e sistemas de informações institucionais acessíveis ao público. A variável dependente foi a autopercepção de saúde. A análise foi realizada por meio de regressão logística binária multinível. Participaram do estudo 1.513 pacientes com DC, sendo 335 (22,1%) com pior autopercepção de saúde. Este estudo revelou a influência da organização/oferta do serviço público de saúde brasileiro e de características individuais na autopercepção de saúde de pacientes com DC.
RESUMO
Resumo Introdução No Brasil, a única droga disponível para o tratamento específico do Trypanosoma cruzi, causador da Doença de Chagas (DC) é o Benzonidazol (BZN), cujas reações adversas podem propiciar a interrupção do tratamento. Objetivo O objetivo desse trabalho é quantificar a proporção de ocorrência de efeitos adversos, descrevê-los e identificar os fatores de risco associados à essa ocorrência. Método Revisão sistemática conduzida de acordo com os padrões estabelecidos pelo Preferred Reporting Items is Systematic Reviews and Metanalyses (PRISMA). Incluíram-se somente ensaios clínicos randomizados controlados. Resultados Dos 134 estudos identificados, cinco foram incluídos. O tamanho da amostra variou de 77 a 2854 pessoas, e a faixa etária dos participantes, variou de zero a 75 anos. Todos os estudos incluídos apontaram reações adversas ao uso do BZN. A frequência de reação adversa chegou a 38% e a mais comum foi o rash cutâneo. O abandono do tratamento devido à reação foi citado em três estudos, variando de 6,4% a 13,4%. Conclusão As reações adversas ao uso do BZN variaram de acordo com a idade do paciente e esquema terapêutico de dose e tempo adotado, sendo o conhecimento médico acerca dessas reações imprescindível para seu uso seguro e adesão ao tratamento.
Abstract Background In Brazil, the only drug available for the treatment of Trypanosoma cruzi, which causes Chagas' Disease (CD), is the Benznidazole (BZN) whose the adverse reactions might lead to treatment dropout. Objective The objective of this study is to quantify the proportion of occurrence of adverse effects, to describe them and to identify the risk factors associated with this occurrence. Method This is a systematic review conducted through the standards established by the Preferred Reporting Items in Systematic Reviews and Metanalyses (PRISMA). Only randomized controlled trials were included. Results Five of 134 studies were included. The sample size ranged from 77 to 2854 people, and the age range of the participants ranged from zero to 75 years old. All included studies reported adverse reactions to BZN use. The frequency of adverse reaction was 38% and the most common reaction was the skin rash. The treatment dropout caused by the adverse reactions was cited in three studies and was ranging from 6.4% to 13.4%. Conclusion The adverse reactions caused by the use of BZN varied with the age of patients and the therapeutic scheme of dose and time adopted. Therefore, medical knowledge is imperative for the safe use of BZN and adherence to treatment.
RESUMO
Objetivo: conhecer o manejo de pacientes com Doença de Chagas (DC) por médicos da Atenção Primária à Saúde (APS) de regiões endêmicas. Método: estudo transversal realizado com 104 médicos da APS de 39 municípios das regiões norte de Minas Gerais e Vale do Jequitinhonha. Foram abordados perfil sociodemográfico, formação acadêmica e prática clínica, por meio de questionário autoaplicado. Resultados: os médicos apresentaram idade média de 33(±9,88) anos, 4(±7,26) anos de atuação na APS, 49% relataram que a graduação não ofereceu formação suficiente em DC. Embora quase 90% tivessem experiência com atendimento de pacientes com DC crônica e 57% com DC aguda, apenas 9% relataram sentir-se totalmente seguros para esses atendimentos e 33% relataram não conhecer o Benzonidazol, único antitripanossômico disponível. Contribuindo para esse quadro, após a graduação, somente 13,3% receberam alguma informação ou treinamento relativo à DC e quase metade recebeu esse treinamento há mais de 4 anos. Há insegurança, desconhecimento e carência de capacitações sobre DC entre profissionais médicos da APS de localidades endêmicas.
Objective: to understand the management of patients with Chagas Disease (CD) by Primary Health Care (PHC) doctors in endemic regions. Methods: cross-sectional study with 104 PHC doctors in 39 municipalities in the northern regions of Minas Gerais and Jequitinhonha Valley. Socio-demographic profile, academic training, and clinical practice were covered through a self-administered questionnaire. Results: the physicians had a mean age of 33 (± 9.88) years, 4 (± 7.26) years experience in the PHC system, and 49% reported that their undergraduate studies did not offer enough training on CD. Although almost 90% had experience with the care of patients with chronic CD and 57% with acute CD, only 9% reported feeling completely secure about these services and 33% reported not knowing about benznidazole, the only antitrypanosomal available. Contributing to this situation, after graduation, only 13.3% received any information or training on CD and almost half received this training more than four years ago. There is insecurity, ignorance, and lack of training on CD among PHC medical professionals in endemic locations.
