Data-driven coaching to improve statewide outcomes in CABG: before and after interventional study.

BACKGROUND: The impact of quality improvement initiatives program (QIP) on coronary artery bypass grafting surgery (CABG) remains scarce, despite improved outcomes in other surgical areas. This study aims to evaluate the impact of a package of QIP on mortality rates among patients undergoing CABG. MATERIALS AND METHODS: This prospective cohort study utilized data from the multicenter database Registro Paulista de Cirurgia Cardiovascular II (REPLICCAR II), spanning from July 2017 to June 2019. Data from 4018 isolated CABG adult patients were collected and analyzed in three phases: before-implementation, implementation, and after-implementation of the intervention (which comprised QIP training for the hospital team). Propensity Score Matching was used to balance the groups of 2170 patients each for a comparative analysis of the following outcomes: reoperation, deep sternal wound infection/mediastinitis ≤30 days, cerebrovascular accident, acute kidney injury, ventilation time >24 h, length of stay <6 days, length of stay >14 days, morbidity and mortality, and operative mortality. A multiple regression model was constructed to predict mortality outcomes. RESULTS: Following implementation, there was a significant reduction of operative mortality (61.7%, P =0.046), as well as deep sternal wound infection/mediastinitis ( P <0.001), sepsis ( P =0.002), ventilation time in hours ( P <0.001), prolonged ventilation time ( P =0.009), postoperative peak blood glucose ( P <0.001), total length of hospital stay ( P <0.001). Additionally, there was a greater use of arterial grafts, including internal thoracic ( P <0.001) and radial ( P =0.038), along with a higher rate of skeletonized dissection of the internal thoracic artery. CONCLUSIONS: QIP was associated with a 61.7% reduction in operative mortality following CABG. Although not all complications exhibited a decline, the reduction in mortality suggests a possible decrease in failure to rescue during the after-implementation period.

The arrival of COVID-19 in Brazil and the impact on coronary artery bypass surgery.

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.

Surgical treatment of patent ductus arteriosus in adults.

OBJECTIVE: To analyze 34 patients submitted to surgical treatment of patent arterial duct with age beyond 18 years old. METHODS: Retrospective data collected from patient's charts with more than eighteen years old, submitted to surgical correction of patent arterial duct between 1997 and 2008 at Instituto do Coração da Faculdade de Medicina da Universidade de São Paulo. RESULTS: The mean age was 28.7 (18 a 53) years and 22 (64.7%) were female. The more prevalent symptom was dyspnea (76.5%). Left lateral thoracotomy was used in 33 (97.1%); the DA was sectioned and sutured in 25 (73.5%) cases and one patient needed cardiopulmonary bypass support. There were eight (23.5%) calcified arterial duct and 12 (35.3%) previous treatment with transcatheter devices were performed. The complication rate was 32%, with one (2.9%) permanent vocal cord palsy. Two (5.8%) patients had residual shunt less than 2mm. Transient left cord voice palsy was observed in 3 (8.8%) The procedure improves functional class (P< 0.0001) and no mortality was observed. CONCLUSION: In this series, the surgical treatment of patent arterial duct in adults could be done without mortality and low incidence of complications.

Tratamento cirúrgico da persistência do canal arterial na população adulta / Surgical treatment of patent ductus arteriosus in adults

OBJETIVO: Analisar uma série de 34 pacientes adultos submetidos ao tratamento cirúrgico da persistência do canal arterial. MÉTODOS: Estudo retrospectivo, com coleta de dados dos prontuários de 34 pacientes consecutivos, com idade superior a 18 anos, com persistência do canal arterial submetidos a correção cirúrgica, no período de 1997 a 2008, no Instituto do Coração da Faculdade de Medicina da Universidade de São Paulo. RESULTADOS: A idade média foi de 28,7 (18 a 53) anos e 22 (64,7%) pacientes eram do sexo feminino. O sintoma mais frequente foi dispneia (76,5%). A toracotomia lateral esquerda foi utilizada em 33 (97,1%) pacientes e o canal arterial foi seccionado e suturado em 25 (73,5%). A circulação extracorpórea (CEC) foi necessária em um paciente. Observou-se calcificação em oito (23,5%) pacientes e 12 (35,3%) haviam sido submetidos à tentativa de fechamento percutâneo. A incidência de complicações foi de 32%, sendo uma permanente, com paralisia de corda vocal (2,9%). Dois (5,8%) pacientes permaneceram com shunt residual e três (8,8%) apresentaram paralisia de corda vocal esquerda transitória. A cirurgia realizada efetivamente levou à melhora da classe funcional (P< 0,0001). Não houve óbitos. CONCLUSÃO: Nesta série de pacientes, o tratamento cirúrgico do canal arterial com técnica convencional em adultos pode ser realizado com baixa morbidade e baixa incidência de complicações.
