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.
Objective this study aimed to determine the incidence of nosocomial infections, the risk
factors and the impact of these infections on mortality among patients undergoing
to cardiac surgery. Methods Retrospective cohort study of 2060 consecutive patients from 2006 to 2012 at the
Santa Casa de Misericórdia de Marília. Results 351 nosocomial infections were diagnosed (17%), 227 non-surgical infections and
124 surgical wound infections. Major infections were mediastinitis (2.0%), urinary
tract infection (2.8%), pneumonia (2.3%), and bloodstream infection (1.7%). The
in-hospital mortality was 6.4%. Independent variables associated with non-surgical
infections were age > 60 years (OR 1.59, 95% CI 1.09 to 2.31), ICU stay > 2
days (OR 5, 49, 95% CI 2.98 to 10, 09), mechanical ventilation > 2 days (OR11,
93, 95% CI 6.1 to 23.08), use of urinary catheter > 3 days (OR 4.85 95% CI 2.95
-7.99). Non-surgical nosocomial infections were more frequent in patients with
surgical wound infection (32.3% versus 7.2%, OR 6.1, 95% CI 4.03 to 9.24).
Independent variables associated with mortality were age greater than 60 years (OR
2.0; 95% CI 1.4 to3.0), use of vasoactive drugs (OR 3.4, 95% CI 1.9 to 6, 0),
insulin use (OR 1.8; 95% CI 1.2 to 2.8), surgical reintervention (OR 4.4; 95% CI
2.1 to 9.0) pneumonia (OR 4.3; 95% CI 2.1 to 8.9) and bloodstream infection (OR =
4.7, 95% CI 2.0 to 11.2). Conclusion Non-surgical hospital infections are common in patients undergoing cardiac
surgery; they increase the chance of surgical wound infection and mortality.
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.
It is observed that death rates in cardiac surgery has decreased, however, root causes that behave like triggers of potentially avoidable deaths (AD), especially in low-risk patients (less bias) are often unknown and underexplored, Phase of Care Mortality Analysis (POCMA) can be a valuable tool to identify seminal events (SE), providing valuable information where it is possible to make improvements in the quality and safety of future procedures. Our results show that in São Paul State, only one third of AD in low-risk cardiac surgery was related to specific surgical problems. After a revisited analysis, 75% of deaths could have been avoided, which in the pre-operative phase, the SE was related judgment, patient evaluation and preparation. In the intra-operative phase, most occurrences could have been avoided if other surgical technique had been used. Sepsis was responsible for 75% of AD in the intensive care unit. In the ward phase, the recognition/management of clinical decompensations and sepsis were the contributing factors. Logistic regression model identified age, previous coronary stent implantation, coronary artery bypass grafting + heart valve surgery, ≥ 2 combined heart valve surgery and hospital-acquired infection as independent predictors of AD.
Background and Aim of the Study
This study analyzed the arrival of coronavirus disease 2019 (COVID‐19) in Brazil and its impact on coronary artery bypass grafting (CABG) surgery.
Methods
Patients undergoing isolated CABG in six hospitals in Brazil were divided into two periods: pre‐COVID‐19 (March–May 2019, N = 468) and COVID‐19 era (March–May 2020, N = 182). Perioperative data were included on a dedicated REDCap platform. Patients with clinical and tomographic criteria and/or PCR (+) for severe acute respiratory syndrome coronavirus 2 infection were considered COVID‐19 (+). Logistic regression analysis was performed to create a multiple predictive model for mortality after CABG in COVID‐19 era.
Results
Compared to 2019, in 2020, CABG surgeries had a 2.8‐fold increased mortality risk (95% confidence interval [CI]: 1–7.6, p = .041), patients who evolved with COVID‐19 had a 11‐fold increased mortality risk (95% CI: 2.2–54.9, p < .003), rates of morbidities and readmission to the intensive care unit. The surgical volume was decreased by 60%. The model to predict mortality after CABG in the COVID‐19 era was validated with good calibration (Hosmer–Lemeshow = 1.43) and discrimination (receiver operating characteristic = 0.78).
Conclusion
The COVID‐19 pandemic had an adverse impact on mortality, morbidity and volume of patients undergoing CABG.
