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.

Extubation in the Operating Room After Coronary Artery Bypass Graft Surgery Reduces Hospital Stay.

OBJECTIVES: The aim of this analysis was to compare the effect of extubating in the operating room (OR) versus and the intensive care unit (ICU) among patients undergoing coronary artery bypass grafting (CABG). DESIGN: A retrospective cohort analysis. SETTING: Ten cardiac referral hospitals in Latin America; participants of the São Paulo Registry of Cardiovascular Surgery II (REPLICCAR II). PARTICIPANTS: The database included a total of 4,015 patients who underwent primary and isolated CABG surgery and were ≥18 years old, of whom 205 patients were extubated in the OR. INTERVENTIONS: The analysis was made after a propensity score matching (PSM) adjustment in the population sample of patients extubated in the OR and ICU by the following variables: sex, age, body mass index, smoking, type of surgery, chronic obstructive pulmonary disease, preoperative atrial fibrillation, cardiopulmonary bypass time, preoperative creatinine, and preoperative left ventricular ejection fraction. MEASUREMENTS AND MAIN RESULTS: This study focused on the analysis of the ICU and hospital length of stay, need for reintubation, morbidity, and mortality. After PSM, 402 patients were analyzed. Both groups had similar baseline characteristics, such as age (p = 0.132), sex (p = 1.00), and estimated risk of prolonged ventilation (>24 hours, p = 0.168); however, the median ventilation time was significantly shorter in the group extubated in the OR compared to the ICU group (5.67 hours v 17.55 hours, p < 0.001). The group of patients extubated in the ICU had a longer postoperative stay (7.54 ± 3.40 days v 6.41 ± 2.91 days, p < 0.001) and longer total hospitalization time (11.49 ± 5.70 days v 10.36 ± 5.72, p = 0.013) compared to those extubated in the OR. The authors did not observe a significant difference in the need for reintubation, morbidity, or mortality rates among the evaluated groups. CONCLUSIONS: In the REPLICCAR II database, extubation performed in the OR was associated with a reduced length of postoperative and total hospital stays compared to extubation in the ICU.

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.
