INTRODUCTION: Situational awareness (SA) describes a team's ability to perceive environmental elements, comprehend their meaning, and anticipate future events. Although SA is consistently described as a critical competency among surgical teams, there is a dearth of research identifying efficacious methods to assess and develop SA in such settings. The aim of this study was to investigate the feasibility of implementing an objective tool that has been used to measure SA in other intense and dynamic environments -the Situation Awareness Global Assessment Technique (SAGAT)-and to examine its ability to predict surgical trainee team performance...

OBJECTIVE: Situation awareness (SA) is a vital construct for decision making in intense, dynamic environments such as trauma resuscitation. Human patient simulation (HPS) allows for a safe environment where individuals can develop these skills. Trauma resuscitation is performed by multidisciplinary teams that are traditionally difficult to globally assess. Our objective was to create and validate a novel tool to measure SA in multidisciplinary trauma teams using a HPS--the Team Situation Awareness Global Assessment Technique (TSAGAT)...

To predict changes of situation awareness (SA) for pilot operating with different display interfaces and tasks, a qualitative analysis and quantitative calculation joint SA model was proposed. Based on the situational awareness model according to the attention allocation built previously, the pilot cognitive process for the situation elements was analyzed according to the ACT-R (Adaptive Control of Thought, Rational) theory, which explained how the SA was produced. To verify the validity of this model, 28 subjects performed an instrument supervision task under different experiment conditions...

Evidence suggests that breakdowns in communication and a lack of situation awareness contribute to poor performance of medical teams. In this pilot study, three interprofessional obstetrical teams determined the feasibility of using the situation awareness global assessment technique (SAGAT) during simulated critical event management of three obstetrical scenarios. After each scenario, teams were asked to complete questionnaires assessing their opinion of how their performance was affected by the introduction of questions during a SAGAT stop...

OBJECTIVES: Situational awareness (SA) refers to the perception of elements in one's environment, the comprehension of their meaning, and the projection of their status in the near future. The SA global assessment technique (SAGAT) is an assessment tool validated for use in a trauma simulation. The goal of this study was to determine the effect of sleep deprivation on residents' performance in a trauma simulation, evaluated by the SAGAT. METHODS: A power analysis determined that 9 residents would be needed to show a significant difference in SAGAT scores (7%)...

Coarctation of the aorta accounts for about 8% of all congenital heart diseases. Since the first successful case of surgical treatment in 1944 by Crafoord and Nylin1 in Sweden, several surgical techniques have been employed in the treatment of this anomaly. Here, we review by illustration the various surgical options in coarctation of the aorta with emphasis on our preferred technique - the extended resection and end-to-end anastomosis. Why the extended resection technique? Our experience - and that of other institutions - has shown that this is a better option in childhood as it is associated with a lesser degree of recoarctation and subsequent need for re-intervention...

Although they have become a widely used experimental technique for identifying differentially expressed (DE) genes, DNA microarrays are notorious for generating noisy data. A common strategy for mitigating the effects of noise is to perform many experimental replicates. This approach is often costly and sometimes impossible given limited resources; thus, analytical methods are needed which increase accuracy at no additional cost. One inexpensive source of microarray replicates comes from prior work: to date, data from hundreds of thousands of microarray experiments are in the public domain...

Mice can learn a food preference from odor cues transmitted on the breath of a conspecific, even if the "demonstrator" is anesthetized. To our knowledge there are no studies examining the effect of anesthetizing the "observer" on development of memory for socially transmitted food preferences (STFP). In Experiment 1 we found that 2-4 month-old F2 C57Bl/6x129sv male and female mice demonstrated a STFP after a 5min exposure to an anesthetized demonstrator mouse when tested 24h later. In Experiment 2, observer mice anesthetized with Sagatal (60 mg/kg) prior to the "social interaction" preferentially avoided the cued food when tested 24h later...

One of the key functionalities in the Enterprise Application Integration (EAI) engines is a dashboard to provide awareness on the message traffic, performance and throughput. Current dashboards present a rich data set but often lacks context to interpret these data. This poster presents a knowledge driven approach in improving the dashboard by presenting contextualized information. The new dashboard will be evaluated by measuring user awareness, as measured by applying a quantitative analysis technique called SAGAT (Situational Awareness Global Assessment Technique) and the results will be presented...
