Society of Cardiovascular Anesthesiologists Clinical Practice Update for Management of Acute Kidney Injury Associated With Cardiac Surgery.

Cardiac surgery-associated acute kidney injury (CS-AKI) is common and is associated with increased risk for postoperative morbidity and mortality. Our recent survey of the Society of Cardiovascular Anesthesiologists (SCA) membership showed 6 potentially renoprotective strategies for which clinicians would most value an evidence-based review (ie, intraoperative target blood pressure, choice of specific vasopressor agent, erythrocyte transfusion threshold, use of alpha-2 agonists, goal-directed oxygen delivery on cardiopulmonary bypass [CPB], and the "Kidney Disease Improving Global Outcomes [KDIGO] bundle of care"). Thus, the SCA's Continuing Practice Improvement Acute Kidney Injury Working Group aimed to provide a practice update for each of these strategies in cardiac surgical patients based on the evidence from randomized controlled trials (RCTs).

Society of Cardiovascular Anesthesiologists/European Association of Cardiothoracic Anaesthetists Practice Advisory for the Management of Perioperative Atrial Fibrillation in Patients Undergoing Cardiac Surgery.

Postoperative atrial fibrillation (poAF) is the most common adverse event after cardiac surgery and is associated with increased morbidity, mortality, and increased hospital and intensive care unit length of stay. Despite progressive improvements in overall cardiac surgical operative mortality and postoperative morbidity, the incidence of poAF has remained unchanged at 30% to 50%. A number of evidence-based recommendations regarding the perioperative management of atrial fibrillation (AF) have been released from leading cardiovascular societies in recent years; however, it is unknown how closely these guidelines are being followed by medical practitioners.

Safety Culture in Cardiac Surgical Teams: Data From Five Programs and National Surgical Comparison.

Background: Little is known about safety culture in the area of cardiac surgery as compared with other types of surgery. The unique features of cardiac surgical teams may result in different perceptions of patient safety and patient safety culture.

Methods: We measured and described safety culture in five cardiovascular surgical centers using the Hospital Survey on Patient Safety Culture, and compared the data with the Agency for Healthcare Research and Quality (AHRQ) 2010 comparative database in surgery and anesthesiology (all types).

Commentary: Sense and sensibility: the role of specialists in health care reform.

How to redesign the incentives structure in the United States to reward effective coordinated care rather than production volume is a staggering public health policy challenge. In the mind of the public, there is a fine distinction between health care rationing and rational health care. Specialists have a vital but underappreciated role in reining in health care costs, but specific incentives to elicit behavior change with positive social outcomes remain ambiguous.

Lack of effectiveness of the pulmonary artery catheter in cardiac surgery.

Background: The pulmonary artery catheter (PAC) continues to be used for monitoring of hemodynamics in patients undergoing coronary artery bypass graft (CABG) surgery despite concerns raised in other settings regarding both effectiveness and safety. Given the relative paucity of data regarding its use in CABG patients, and given entrenched practice patterns, we assessed the impact of PAC use on fatal and nonfatal CABG outcomes as practiced at a diverse set of medical centers.

Methods: Using a formal prospective observational study design, 5065 CABG patients from 70 centers were enrolled between November 1996 and June 2000 using a systemic sampling protocol.

Point-of-care electronic prompts: an effective means of increasing compliance, demonstrating quality, and improving outcome.

Background: Incentives based on quality indicators such as the Surgical Care Improvement Project core measures (SCIP 1) encourage implementation of evidence-based guidelines consistently into clinical practice. Information systems with point-of-care electronic prompts (POCEPs) can facilitate adoption of processes and benchmark performance. We evaluated the effectiveness of POCEPs on rates of antibiotic administration within 60 minutes of surgical incision and effect on outcome in a prospective observational trial.

Predictive value of the National Institutes of Health Stroke Scale and the Mini-Mental State Examination for neurologic outcome after coronary artery bypass graft surgery.

Objective: We intended to define the role of the National Institutes of Health Stroke Scale and the Mini-Mental State Examination in identifying adverse neurologic outcomes in a large international sample of patients undergoing cardiac surgery.

Methods: We evaluated 4707 patients undergoing cardiac surgery with cardiopulmonary bypass at 72 centers in 17 countries between November 1996 and June 2000. Prespecified overt neurologic outcomes were categorized as type I (clinically diagnosed stroke, transient ischemic attack, encephalopathy, or coma) or type II (deterioration of intellectual function).

Hormone replacement therapy is safe in women undergoing coronary artery bypass grafting.

In postmenopausal women, hormone replacement therapy (HRT) does not substantially reduce the incidence of cardiovascular disease and may produce a short-term increase in risk. Therefore, we investigated whether HRT increased risk in patients with severe coronary artery disease necessitating surgery We prospectively studied 4,782 patients undergoing coronary artery bypass grafting at 70 centers in 17 countries from November 1996 through June 2000. Patients were selected using a systematic sampling technique.

Perturbations in laboratory values after coronary artery bypass graft surgery with cardiopulmonary bypass.

Objective: The purpose of this study was to describe the sequential changes in commonly obtained laboratory values after coronary artery bypass grafting (CABG) with cardiopulmonary bypass (CPB).

Methods: The authors examined laboratory data from 375 patients who underwent uncomplicated CABG with CPB in a multicenter clinical trial of a medication for postoperative pain. Data were obtained preoperatively, at the time of postoperative extubation, and at 4 subsequent intervals ending 14 days after extubation.

Does off-pump coronary artery bypass reduce the incidence of clinically evident renal dysfunction after multivessel myocardial revascularization?

In this prospective, observational trial, we determined whether off-pump coronary artery bypass (OPCAB) was associated with less postoperative renal dysfunction (RD) compared with coronary bypass surgery with cardiopulmonary bypass (CABG). All patients undergoing primary, isolated coronary surgery at our institution in the year 2000 participated. Data collected on each patient included demographics, preoperative risk factors for RD, perioperative events, and serum creatinine concentrations from date of admission until discharge or death.
