Anesthesia Adverse Events Voluntarily Reported in the Veterans Health Administration and Lessons Learned.
Anesthesia providers have long been pioneers in patient safety. Despite remarkable efforts, anesthesia errors still occur, resulting in complications, injuries, and even death. The Veterans Health Administration (VHA) National Center of Patient Safety uses root cause analysis (RCA) to examine why system-related adverse events occur and how to prevent future similar events. This study describes the types of anesthesia adverse events reported in VHA hospitals and their root causes and preventative actions. ⋯ This analysis points to the need for systemwide implementation of human factors engineering-based approaches to work toward further eliminating anesthesia-related adverse events. Such actions include standardization of processes, forcing functions, separating storage of look-alike sound-alike medications, limiting stock of high-risk medication strengths, bar coding medications, use of cognitive aids such as checklists, and high-fidelity simulation.

Antiemetic Prophylaxis as a Marker of Health Care Disparities in the National Anesthesia Clinical Outcomes Registry.
US health care disparities persist despite repeated countermeasures. Research identified race, ethnicity, gender, and socioeconomic status as factors, mediated through individual provider and/or systemic biases; little research exists in anesthesiology. We investigated antiemetic prophylaxis as a surrogate marker for anesthesia quality by individual providers because antiemetics are universally available, indicated contingent on patient characteristics (gender, age, etc), but independent of comorbidities and not yet impacted by regulatory or financial constraints. We hypothesized that socioeconomic indicators (measured as insurance status or median income in the patients' home zip code area) are associated with the utilization of antiemetic prophylaxis (as a marker of anesthesia quality). ⋯ Our analyses of NACOR anesthesia records raise concerns that patients with lower socioeconomic status may receive inferior anesthesia care provided by individual anesthesiologists, as indicated by less antiemetics administered. Effects persisted after we controlled for important patient characteristics and for procedure and provider influences. Findings were robust to sensitivity analyses. Our results challenge the notion that anesthesia providers do not contribute to health care disparities.

An Automated Critical Event Screening and Notification System to Facilitate Preanesthesia Record Review.
Anesthesia information management systems make prior anesthesia records readily available for review when patients return for a subsequent procedure but may create a problem of too much documentation to review in a limited amount of time. We implemented a screening tool to facilitate the identification of critical documentation for review. ⋯ We created a system to automatically detect critical events in prior anesthesia records for the purpose of forewarning the anesthesia care team when the same patient returns for another procedure. Inclusion of these warnings on the daily case schedule was associated with an increased frequency of preanesthesia review of old records.

Continuous Noninvasive Arterial Pressure Monitoring Using the Vascular Unloading Technique (CNAP System) in Obese Patients During Laparoscopic Bariatric Operations.
Increasing rates of obesity create new challenges for hemodynamic monitoring in the perioperative phase. Continuous monitoring of arterial pressure (AP) is important in severely obese patients who are at particular risk for cardiovascular complications. Innovative technologies for continuous noninvasive AP monitoring are now available. In this study, we aimed to compare continuous noninvasive AP measurements using the vascular unloading technique (CNAP system; CNSystems, Graz, Austria) compared with invasive AP measurements (radial arterial catheter) in severely obese patients during laparoscopic bariatric surgery. ⋯ In the setting of laparoscopic bariatric surgery, continuous noninvasive AP monitoring with the CNAP system showed good trending capabilities compared with continuous invasive AP measurements obtained with a radial arterial catheter. However, absolute CNAP- and arterial catheter-derived AP values were not interchangeable.
