Abstract Background A cost of illness (COI) study aims to evaluate the socioeconomic burden that an illness imposes on society as a whole. This study aimed to describe the resources used, patterns of care, direct cost, and loss of productivity due to systemic lupus erythematosus (SLE) in Brazil. Methods This 12-month, cross-sectional, COI study of patients with SLE (ACR 1997 Classification Criteria) collected data using patient interviews (questionnaires) and medical records, covering: SLE profile, resources used, morbidities, quality of life (12-Item Short Form Survey, SF-12), and loss of productivity. Patients were excluded if they were retired or on sick leave for another illness. Direct resources included health-related (consultations, tests, medications, hospitalization) or non-health-related (transportation, home adaptation, expenditure on caregivers) hospital resources. Costs were calculated using the unit value of each resource and the quantity consumed. A gamma regression model explored cost predictors for patients with SLE. Results Overall, 300 patients with SLE were included (92.3% female, mean [standard deviation (SD)] disease duration 11.8 [7.9] years), of which 100 patients (33.3%) were on SLE-related sick leave and 46 patients (15.3%) had stopped schooling. Mean (SD) travel time from home to a care facility was 4.4 (12.6) hours. Antimalarials were the most commonly used drugs (222 [74.0%]). A negative correlation was observed between SF-12 physical component and SLE Disease Activity Index (- 0.117, p = 0.042), Systemic Lupus International CollaboratingClinics/AmericanCollegeofRheumatology Damage Index (- 0.115, p = 0.046), medications/day for multiple co-morbidities (- 0.272, p < 0.001), SLE-specific drugs/day (- 0.113, p = 0.051), and lost productivity (- 0.570, p < 0.001). For the mental component, a negative correlation was observed with medications/day for multiple co-morbidities (- 0.272, p < 0.001), SLE-specific medications/day (- 0.113, p = 0.051), and missed appointments (- 0.232, p < 0.001). Mean total SLE cost was US$3,123.53/patient/year (median [interquartile range (IQR)] US$1,618.51 [$678.66, $4,601.29]). Main expenditure was medication, with a median (IQR) cost of US$910.62 ($460, $4,033.51). Mycophenolate increased costs by 3.664 times (p < 0.001), and inflammatory monitoring (erythrocyte sedimentation rate or C-reactive protein) reduced expenditure by 0.381 times (p < 0.001). Conclusion These results allowed access to care patterns, the median cost for patients with SLE in Brazil, and the differences across regions driven by biological, social, and behavioral factors. The cost of SLE provides an updated setting to support the decision-making process across the country.

RESUMO INTRODUÇÃO Insuficiência cardíaca após infarto agudo do miocárdio é um evento bastante frequente, que tende a aumentar conforme as melhorias que o tratamento dos quadros agudos têm acarretado a números maiores de sobreviventes de infarto. OBJETIVO A revisão sistemática sumarizou as evidências relativas à eficácia e segurança do dispositivo de partição ventricular (PARACHUTE®) em pacientes com IC pós-IAM apical ou de parede anterior. MÉTODOS Foram analisados estudos publicados entre janeiro de 2002 e outubro de 2016 nas bases Embase, Medline, Colaboração Cochrane, Lilacs, Web of Science e Scopus. A seleção dos estudos, a extração dos dados e a avaliação de qualidade metodológica foram realizadas por dois revisores independentes, com as discordâncias resolvidas por consenso. RESULTADOS Somente estudos prospectivos sem grupo controle foram identificados. Seis estudos foram incluídos, com média de 34 participantes e de follow-up de 13 meses. Foram avaliados desfechos clínicos, funcionais, hemodinâmicos e qualidade de vida. O maior percentual de re-hospitalização por IC foi de 29,4%, com 36 meses de seguimento, e de mortalidade foi de 8,4%, com 12 meses de seguimento, por motivos cardiovasculares não especificados. Melhorias estatisticamente significantes foram constatadas em alguns dos estudos que avaliaram mudanças nos índices de volume do ventrículo esquerdo, distância medida pelo teste de caminhada de 6 minutos, classificação funcional da New York Heart Association e qualidade de vida, em análises do tipo antes e depois do procedimento. CONCLUSÕES A presente revisão indica que não existem evidências de qualidade disponíveis que permitam afirmar a eficácia e segurança do PARACHUTE® no tratamento da condição de base.

SUMMARY INTRODUCTION Heart failure due to an acute myocardial infarction is a very frequent event, with a tendency to increase according to improvements in the treatment of acute conditions which have led to larger numbers of infarction survivors. OBJECTIVE The aim of this study is to synthesize the evidence, through a systematic review, on efficacy and safety of the device in patients with this basic condition. METHODS Studies published between January 2002 and October 2016 were analysed, having as reference databases Embase, Medline, Cochrane Library, Lilacs, Web of Science and Scopus. The selection of studies, data extraction and methodological quality assessment of studies were examined by two independent reviewers, with disagreements resolved by consensus. RESULTS Only prospective studies without control group were identified. Six studies were included, with averages of 34 participants and follow-up of 13 months. Clinical, functional, hemodynamic and quality of life outcomes were evaluated. The highest mortality rate was 8.4% with 12-month follow-up for unspecified cardiovascular reasons, and heart failure rehospitalization was 29.4% with 36-month follow-up. Statistically significant improvements were found only in some of the studies which evaluating changes in left ventricular volume indices, the distance measured by the six-minute walk test, New York Heart Association functional classification, and quality of life, in pre and post-procedure analysis. CONCLUSIONS The present review indicates that no available quality evidence can assert efficacy and safety of PARACHUTE® in the treatment of heart failure after apical or anterior wall myocardial infarction.

O objetivo foi comparar a relação de custo-efetividade entre o uso de cateteres cardíacos novos com cateteres reprocessados sob a perspectiva de uma instituição pública federal. Foi elaborado um modelo analítico de decisão elaborado para estimar a razão de custo-efetividade entre duas estratégias de utilização de materiais para cateterismo cardíaco utilizando, como desfecho clínico, a ocorrência de reação pirogênica. Os custos foram estimados por coleta direta nos setores envolvidos e valorados em Real (R$) para o ano de 2012. A árvore de decisão foi construída com as probabilidades de pirogenia descritas em estudo clínico. O custo para o reúso foi de R$ 109,84, e, para cateteres novos, de R$ 283,43. A estratégia de reúso demonstrou ser custo-efetiva, e a razão de custo-efetividade incremental indicou que, para evitar um caso de pirogenia, serão gastos R$ 13.561,75. O estudo aponta o reúso de cateteres como uma estratégia de menor custo comparada ao uso exclusivo de cateteres novos e pode contribuir para a tomada de decisão dos gestores.

The aim of this study was to compare the cost-effectiveness ratio of new versus reprocessed coronary artery catheters in a Federal public hospital. This was an analytical decision-making model prepared to estimate the cost-effectiveness ratio between two strategies in the use of materials in coronary artery catheterization, with pyrogenic reaction as the clinical outcome. Costs were estimated using direct data collection in the respective catheterization services and expressed in Brazilian Reais (R$), with 2012 as the reference year. The decision-making tree was constructed with the probabilities of pyrogenic reaction as described in a clinical trial. The cost per catheter for reuse was R$ 109.84, as compared to R$ 283.43 for a new catheter. The reutilization strategy proved to be cost cost-effective, and the incremental cost-effectiveness ratio indicated that R$ 13,561.75 would be spent to avoid one case of pyrogenic reaction. The study identified reuse of coronary artery catheters as a lower cost strategy compared to the exclusive use of new catheters, thus potentially assisting decision-making by health administrators.

El objetivo fue comparar la relación coste-eficacia en la reutilización de catéteres cardíacos respecto a los nuevos, bajo la perspectiva de un servicio público. Se utilizó un modelo analítico con el objeto de estimar la relación coste-efectividad entre las dos estrategias para el uso de materiales en el cateterismo cardíaco, utilizando la ocurrencia de reacción pirogénica como resultados clínicos. Los costes fueron estimados por la recogida directa en los sectores implicados y se expresan en reales (R$) para el año 2012. Un diagrama de decisiones se construyó con las probabilidades pirogénicas descritas en el estudio clínico. El coste de la reutilización era de R$ 109,84 y de R$ 283,43 por catéteres nuevos. La estrategia de reutilización ha demostrado ser coste-efectiva y la tasa de coste-efectividad incremental indicó que para prevenir un caso pirogénico se gastarían R$ 13,561.75. El estudio demuestra que la reutilización de catéteres es una estrategia de menor coste, en comparación con el uso exclusivo de los nuevos catéteres, y puede contribuir a la toma de decisiones.
