Triage, the first step in the assessment of emergency department patients, occurs in a highly dynamic environment that functions under constraints of time, physical space, and patient needs that may exceed available resources. Through triage, patients are placed into one of a limited number of categories using a subset of diagnostic information. To(More)

OBJECTIVE To assess pediatric residents' readiness to use computer-aided instruction (CAI). DESIGN Survey. SETTING Pediatric residency program based in a tertiary care children's hospital. PARTICIPANTS Four pediatric residency classes. ASSESSMENT INSTRUMENT: Self-administered questionnaire. MAIN OUTCOME MEASURES Residents' access to computers and(More)
Participant attrition may be a significant threat to the generalizability of the results of educational research studies if participants who do not persist in a study differ from those who do in ways that can affect the experimental outcomes. A multi-center trial of the efficacy of different computer-based instructional strategies gave us the opportunity to(More)
BACKGROUND At present, what students read after an outpatient encounter is largely left up to them. Our objective was to evaluate the education efficacy of a clinical education model in which the student moves through a sequence that includes immediately reinforcing their learning using a specifically designed computer tutorial. METHODS Prior to a 14-day(More)
BACKGROUND The Complete Blood Count (CBC) is a test frequently performed on children presenting to the Pediatric Emergency Department (PED), usually for the evaluation of an infectious illness. The CBC also allows for screening for Iron-deficiency Anemia. This study aims to determine the prevalence of a low Mean Cell Volume (MCV) in children having a CBC(More)
Signal detection theory (SDT) parameters can describe a learner's ability to discriminate (d') normal from abnormal and the learner's criterion (λ) to under or overcall abnormalities. To examine the serial changes in SDT parameters with serial exposure to radiological cases. 46 participants were recruited for this study: 20 medical students (MED), 6(More)
Background. The Emergency Department (ED) is a daunting environment for the medical learner. Time pressures on the attending physicians mean that the learning needs of the medical student may, quite appropriately, be given a lower priority than the clinical needs of the patients. We propose that a collection of brief focused computer tutorials presented at(More)
Sequential context effects, the psychological interactions occurring between the events of successive trials when a sequence of similar stimuli are judged, have interested psychologists for decades. It has been well established that individuals exhibit sequential context effects in psychophysical experiments involving unidimensional stimuli. Recent evidence(More)
