The purpose of this paper is to describe a framework for evaluating image segmentation algorithms. Image segmentation consists of object recognition and delineation. For evaluating segmentation methods, three factors-precision (reliability), accuracy (validity), and efficiency (viability)-need to be considered for both recognition and delineation. To assess(More)
PURPOSE This paper is a review of representative research on the impact of acute stressors on the clinical performance of individuals and teams. METHOD The Sciences Citation Index, Medline, and Psychinfo were used to search for articles up to and including 2008. The search terms were stress/tension/arousal/anxiety/cortisol/threat,(More)
OBJECTIVE Previous research has revealed a pedagogical benefit of instructing novice diagnosticians to utilise a combined approach to clinical reasoning (familiarity-driven pattern recognition combined with a careful consideration of the presenting features) when diagnosing electrocardiograms (ECGs). This paper reports 2 studies demonstrating that the(More)
OBJECTIVES Training and practice in medicine are inherently stressful. Research into the effects of acute stressors has revealed significant variability in individual responses to stressors, with performance impairments occurring in those who demonstrate elevated subjective and physiological responses. Cognitive appraisals (subjective assessment of(More)
BACKGROUND Simulation-based training is useful in improving physicians' skills. However, no randomized controlled trials have been able to demonstrate the effects of simulation teaching in real-life patient care. This study aimed to determine whether simulation-based training or an interactive seminar resulted in better patient care during weaning from(More)
BACKGROUND We carried out a prospective, randomized, 4-arm study including control arm, blinding of examiners to determine effectiveness of computer-based video instruction (CBVI) and different types of expert feedback (concurrent and summary) on learning of a basic technical skill. METHODS Using bench models, participants were pre-tested on a suturing(More)
BACKGROUND Computer-based video training (CBVT) provides flexible opportunities for surgical trainees to learn fundamental technical skills, but may be ineffective in self-directed practice settings because of poor trainee self-assessment. This study examined whether CBVT is effective in a self-directed learning environment among novice trainees. METHODS(More)
A significant proportion of physicians and medical trainees experience stress-related anxiety and burnout resulting in increased absenteeism and disability, decreased patient satisfaction, and increased rates of medical errors. A review and meta-analysis was conducted to examine the effectiveness of interventions aimed at addressing stress, anxiety, and(More)
BACKGROUND Simulation experience alone without debriefing is insufficient for learning. Standardized multimedia instruction has been shown to be useful in teaching surgical skills but has not been evaluated for use as an adjunct in crisis management training. Our primary purpose in this study was to determine whether standardized computer-based multimedia(More)
INTRODUCTION Human factors have been identified as root causes of human error in medicine. The "Anesthetists' Non-Technical Skills (ANTS) system" evaluates the effect of simulation training and debriefing on nontechnical skills (NTS). Studies suggest that residents' NTS may improve after simulation training but the effect on NTS of practicing(More)
