Lactate dehydrogenase (LDH) in serum has recently been introduced into the American Joint Committee on Cancer (AJCC) staging system for cutaneous melanoma because of its prognostic value. We hypothesised LDH to be of value in discriminating melanoma patients entering AJCC stage IV from patients staying in AJCC stages I, II or III. Lactate dehydrogenase was(More)
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., their coordination activities) to changing situational demands is crucial to team performance and, thus, to patient(More)
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. In particular, we were interested in whether the relationship between monitoring behavior and team performance was moderated by team mental model(More)
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(More)
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(More)
BACKGROUND Intraoperative monitoring of neuronal function is important in a variety of surgeries. The type of general anaesthetic used can affect the interpretation and quality of such recordings. Although the principal effects of general anaesthetics are synaptically mediated, the extent to which they affect excitability of the peripheral afferent nervous(More)
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. METHODS Participants anonymously completed a(More)
