Background: To capture preventable peri-operative patient harm and guide improvement initiatives, many quality indicators (QIs) have been developed. Several National Anaesthesiologists Societies (NAS) in Europe have implemented quality indicators. To date, the definitions, validity and dissemination of such quality indicators, and their comparability with validated published indicators are unknown.

Purpose Of Review: Routine monitoring of care quality is fundamental considering the high reported rates of preventable perioperative morbidity and mortality. However, no set of valid and feasible quality indicators is available as the gold standard for comprehensive routine monitoring of the overall quality of perioperative care. The purpose of this review is to describe underlying difficulties, to summarize current trends and initiatives and to outline the perspectives in support of suitable perioperative quality indicators.

Background: Patient safety is a key concern of anaesthesiology practice. However, good practices are often not widely shared between departments and hospitals, whether within or between countries.

Objective: We aimed to collect and analyse safety practices and tips from anaesthesiology departments around Europe in order to facilitate successful transfer of safety knowledge.

Purpose Of Review: Recent research points to considerable rates of preventable perioperative patient harm and anaesthesiologists' concerns about eroding patient safety. Anaesthesia has always been at the forefront of patient safety improvement initiatives. However, factual local safety improvement requires local measurement, which may be afflicted by barriers to data collection and improvement activities.

: Patient safety is an activity to mitigate preventable patient harm that may occur during the delivery of medical care. The European Board of Anaesthesiology (EBA)/European Union of Medical Specialists had previously published safety recommendations on minimal monitoring and postanaesthesia care, but with the growing public and professional interest it was decided to produce a much more encompassing document. The EBA and the European Society of Anaesthesiology (ESA) published a consensus on what needs to be done/achieved for improvement of peri-operative patient safety.

Background: The Helsinki Declaration on Patient Safety was launched in 2010 by the European Society of Anaesthesiology and the European Board of Anaesthesiology. It is not clear how widely its vision and standards have been adopted.

Objective: To explore the role of the Helsinki Declaration in promoting and maintaining patient safety in European anaesthesiology.

Background: The perioperative mortality rate (POMR) is used as a quality indicator to monitor health care system performance at regional and national levels. The Swiss Federal Office of Public Health publishes national in-hospital mortality rates for several indicator conditions and indicator operation types (IORs). We investigated long-term time trends of POMRs from 1998-2014.

Background: Underreporting of intraoperative events in anaesthesia is well-known and compromises quality documentation. The reasons for such omissions remain unclear. We conducted a questionnaire-based survey of anaesthesia staff to explore perceived barriers to reliable documentation during anaesthesia.

Purpose Of Review: Despite the benefits of rapidly advancing therapeutic and diagnostic possibilities, the perioperative setting still exposes patients to significant risks of adverse events and harm. Anesthesiologists are in midstream of perioperative care and can make significant contributions to patient safety and patient outcomes. This article reviews recent research results outlining the current trends of perioperative patient harm and summarizes the evidence in favor of patient safety practices.

This paper builds on and extends theory on team functioning in high-risk environments. We examined 2 implicit coordination behaviors that tend to emerge autochthonously within high-risk teams: team member monitoring and talking to the room. Focusing on nonrandom patterns of behavior, we examined sequential patterns of team member monitoring and talking to the room in higher- and lower-performing action teams working in a high-risk health care environment.

Background: Our goal in this study was to test the relationship between speaking up--i.e., questioning, correcting, or clarifying a current procedure--and technical team performance in anesthesia.

In the present study, we investigated how two team mental model properties (similarity vs. accuracy) and two forms of monitoring behavior (team vs. systems) interacted to predict team performance in anesthesia.

Objective: This field study aimed at examining the role of anesthesia teams' adaptive coordination in managing changing situational demands, such as in nonroutine events (NREs).

Background: Medical teams' ability to adapt their teamwork (e.g.

Background: Leadership plays a crucial role in teams working in complex environments, and research has shown that shared leadership where all team members perform leadership functions is an effective strategy. The authors aimed to describe shared leadership patterns during anaesthesia induction and show how they are linked to team performance.

Methods: 12 anaesthesia teams consisting of one resident and one nurse during a simulated anaesthesia induction including a non-routine event (asystole) were videotaped, and two kinds of leadership behaviour (content-oriented and structuring) were coded.

Background: Endothelial progenitor cells play a pivotal role in tissue repair, and thus are used for cell replacement therapies in "regenerative medicine." We tested whether the anesthetic sevoflurane would modulate growth or mobilization of these angiogenic cells.

Methods: In an in vitro model, mononuclear cells isolated from peripheral blood of healthy donors were preconditioned with sevoflurane (3 times 30 min at 2 vol% interspersed by 30 min of air).

Background: The noble gas helium is devoid of anesthetic effects, and it elicits cardiac preconditioning. We hypothesized that inhalation of helium provides protection against postocclusive endothelial dysfunction after ischemia-reperfusion of the forearm in humans.

Methods: Eight healthy male subjects were enrolled in this study with a crossover design.

Background: Sevoflurane can be used as sedative-analgesic drug with endothelial protective properties. We tested whether low-dose sevoflurane inhalation provides sustained inhibition of detrimental granulocyte-platelet aggregation in humans.

Methods: Ten healthy male volunteers were enrolled in this crossover study.

We present a rare complication after open-heart surgery resulting in compression of the superior vena cava (SVC) with the concurrent findings of the hypertrophic obstructive cardiomyopathy physiology. A 59-year-old woman developed a low cardiac output syndrome, persistent hypotension, and increasing filling pressures after emergency replacement of the ascending aorta and resuspension of the aortic valve due to a type A aortic dissection. Transesophageal echocardiography (TEE) evaluation revealed partial SVC obstruction, under-filled left ventricle (LV), and a persistent mitral systolic anterior motion with increasing pressure gradient in the left ventricular outflow tract (LVOT).

Background: Neuraxial blockade is used as primary anesthetic technique in one third of surgical procedures. The authors tested whether bisoprolol would protect patients at risk for cardiovascular complications undergoing surgery with spinal block.

Methods: The authors performed a double-blinded, placebo-controlled, multicenter trial to compare the effect of bisoprolol with that of placebo on 1-yr composite outcome including cardiovascular mortality, nonfatal myocardial infarction, unstable angina, congestive heart failure, and cerebrovascular insult.
