The quality of data in electronic healthcare databases is a critical component when used for research and health practice. The aim of the present study was to assess the data quality in the Paulista Cardiovascular Surgery Registry II (REPLICCAR II) using two different audit methods, direct and indirect. The REPLICCAR II database contains data from 9 hospitals in São Paulo State with over 700 variables for 2229 surgical patients. The data collection was performed in REDCap platform using trained data managers to abstract information. We directly audited a random sample (n = 107) of the data collected after 6 months and indirectly audited the entire sample after 1 year of data collection. The indirect audit was performed using the data management tools in REDCap platform. We computed a modified Aggregate Data Quality Score (ADQ) previously reported by Salati et al. (2015). The agreement between data elements was good for categorical data (Cohen κ = 0.7, 95%CI = 0.59-0.83). For continuous data, the intraclass coefficient (ICC) for only 2 out of 15 continuous variables had an ICC < 0.9. In the indirect audit, 77% of the selected variables (n = 23) had a good ADQ score for completeness and accuracy. Data entry in the REPLICCAR II database proved to be satisfactory and showed competence and reliable data for research in cardiovascular surgery in Brazil.

ObjectiveTo report the early results of the BYPASS project - the Brazilian registrY of adult Patient undergoing cArdiovaScular Surgery - a national, observational, prospective, and longitudinal follow-up registry, aiming to chart a profile of patients undergoing cardiovascular surgery in Brazil, assessing the data harvested from the initial 1,722 patients.MethodsData collection involved institutions throughout the whole country, comprising 17 centers in 4 regions: Southeast (8), Northeast (5), South (3), and Center-West (1). The study population consists of patients over 18 years of age, and the types of operations recorded were: coronary artery bypass graft (CABG), mitral valve, aortic valve (either conventional or transcatheter), surgical correction of atrial fibrillation, cardiac transplantation, mechanical circulatory support and congenital heart diseases in adults.Results83.1% of patients came from the public health system (SUS), 9.6% from the supplemental (private insurance) healthcare systems; and 7.3% from private (out-of -pocket) clinic. Male patients comprised 66%, 30% were diabetics, 46% had dyslipidemia, 28% previously sustained a myocardial infarction, and 9.4% underwent prior cardiovascular surgery. Patients underwent coronary artery bypass surgery were 54.1% and 31.5% to valve surgery, either isolated or combined. The overall postoperative mortality up to the 7th postoperative day was 4%; for CABG was 2.6%, and for valve operations, 4.4%.ConclusionThis first report outlines the consecution of the Brazilian surgical cardiac database, intended to serve primarily as a tool for providing information for clinical improvement and patient safety and constitute a basis for production of research protocols.

Introduction Coronary artery bypass grafting (CABG) is the most frequently performed heart surgery in Brazil. Recent international guidelines recommend that national societies establish a database on the practice and results of CABG. In anticipation of the recommendation, the BYPASS Registry was introduced in 2015. Objective To analyze the profile, risk factors and outcomes of patients undergoing CABG in Brazil, as well as to examine the predominant surgical strategy, based on the data included in the BYPASS Registry. Methods A cross-sectional study of 2292 patients undergoing CABG surgery and cataloged in the BYPASS Registry up to November 2018. Demographic data, clinical presentation, operative variables, and postoperative hospital outcomes were analyzed. Results Patients referred to CABG in Brazil are predominantly male (71%), with prior myocardial infarction in 41.1% of cases, diabetes in 42.5%, and ejection fraction lower than 40% in 9.7%. The Heart Team indicated surgery in 32.9% of the cases. Most of the patients underwent cardiopulmonary bypass (87%), and cardioplegia was the strategy of myocardial protection chosen in 95.2% of the cases. The left internal thoracic artery was used as a graft in 91% of the cases; the right internal thoracic artery, in 5.6%; and the radial artery in 1.1%. The saphenous vein graft was used in 84.1% of the patients, being the only graft employed in 7.7% of the patients. The median number of coronary vessels treated was 3. Operative mortality was 2.8%, and the incidence of cerebrovascular accident was 1.2%. Conclusion CABG data in Brazil provided by the BYPASS Registry analysis are representative of our national reality and practice. This database constitutes an important reference for indications and comparisons of therapeutic procedures, as well as to propose subsequent models to improve patient safety and the quality of surgical practice in the country.

Objective: The aim of this study was to assess the performance of the European System of Cardiac Operation Risk Evaluation (EuroSCORE) model to predict mortality of patients undergoing coronary artery bypass surgery in the Cardiovascular Surgery Division of Santa Casa de São Paulo Medical School.Methods: From May 2005 to November 2006, 100 consecutive patients undergoing coronary artery bypass surgery were retrospectively analyzed. The records of these patients were reviewed in order to retrieve the variables included in the EuroSCORE method. The correlation of predicted and observed mortality was compared. Statistical analysis was performed using the chi-square test for univariate analysis and the Hosmer-Lemeshow test for logistic regression.Results: Hospital mortality was 5%. The EuroSCORE univariate analysis findings were as follows: score 0-2 predicted mortality 0.40%, observed 0.00%; score 3-5 predicted mortality 1.45%, observed 0.00%; score greater than 6 predicted mortality 3.15%, observed 7.94%. In spite of these differences the p-value was 0.213 demonstrating no statistical significance. The p-value for the HosmerLemeshow test was < 0.001 indicating poor calibration of the model for this sample.Conclusion: The EuroSCORE model is a simple, 263CAMPAGNUCCI, VP ET AL -EuroSCORE and the patients undergoing coronary bypass surgery at Santa Casa de São Paulo Aplicamos o teste do qui-quadrado para análise univariada e o teste de Hosmer-Lemeshow para ajuste do modelo de regressão logística.Resultados: A mortalidade hospitalar foi 5,0%. Na análise univariada, para escore 0-2 a mortalidade prevista pelo EuroSCORE foi de 0,40% e a encontrada 0%. Para o escore 3-5, a mortalidade prevista foi de 1,45% e a encontrada 0%. Para escore >6, a mortalidade prevista foi de 3,15% e a encontrada 7,94%. As discrepâncias entre as porcentagens observadas e previstas não foram estatisticamente significantes (p = 0,213

Os autores apresentam a experiência com a técnica desenvolvida em 1983, na Faculdade de Ciências Médicas da Santa Casa de São Paulo, que consiste em substituir a circulação extracorpórea nas operações de revascularização do miocárdio, por uma derivação (shunt), introduzida na luz da coronária. Este shunt consiste em um pequeno tubo de silicone, flexível, transparente, com diâmetros variando de 1 a 3 mm, que permanece na luz do vaso durante a feitura da anastomose entre o enxerto e a coronária. Esta técnica oferece mais segurança ao paciente, por dispensar o uso da circulação extracorpórea e, conseqüentemente, os seus malefícios, além de evitar isquemia do miocárdio durante a anastomose e mantendo um campo cirúrgico sem sangue, facilitando, assim, a realização da anastomose. De 1983 a 1995, foram operados 419 pacientes, tendo sido realizados 671 enxertos, dos quais 153 com a artéria torácica interna para as coronárias das faces anterior e inferior do coração. A mortalidade hospitalar foi de 1,43%, com 1,67% de incidência de infarto do miocárdio no intra-operatório. A técnica mostrou ser segura, sem complicações graves durante o seu emprego. Os pacientes evoluíram bem no pós-operatório imediato, necessitando menor tempo de intubação, menor permanência na UTI ou internação. Em um grupo inicial estudou-se a qualidade das anastomoses, através da cinecoronariografia pós-operatória em um período médio de 24 meses, mostrando uma taxa de enxertos pérvios de 84%. A técnica mostrou ser simples, segura e econômica, além dos benefícios ao paciente, por ser menos agressiva. Com o advento da cirurgia minimamente invasiva, esta técnica traz a contribuição definitiva para maior segurança dos pacientes.
An analysis was made of the results in a group of 419 patients that underwent myocardial revascularization without cardiopulmonary bypass, by means of a technique using a temporary intraluminal shunt (TIS) described originally by Rivetti and Gandra in 1991. The technique consists of inserting a shunt of a flexible and transparent sylastic tube with external diameter varying from 1 mm to 3 mm into the coronary artery which allows distal irrigation of the coronary artery during the anastomosis between the vein or mammary artery and the coronaries. It offers safety to the patient by avoiding ischemia and its consequences, by molding the coronary artery and maintaining a bloodless field. Mortality was 1,4% in this series and 1,6% of myocardial infarction. There were no life-threatening complications during the procedure. There were no complications similar those normally occurring in the post-operative period of cardiopulmonary procedures. This technique is useful for any patient with coronary stenosis in the antero-diaphragmatic region, but it also provided a good quality of the anastomosis in the cases studied

The objectives of this study were to describe a novel statewide registry for cardiac surgery in Brazil (REPLICCAR), to compare a regional risk model (SPScore) with EuroSCORE II and STS, and to understand where quality improvement and safety initiatives can be implemented. Methods A total of 11 sites in the state of São Paulo, Brazil, formed an online registry platform to capture information on risk factors and outcomes after cardiac surgery procedures for all consecutive patients. EuroSCORE II and STS values were calculated for each patient. An SPScore model was designed and compared with EuroSCORE II and STS to predict 30day outcomes: death, reoperation, readmission, and any morbidity.
