  • Performance of emergency medicine residents on a novel practice examination using visual stimuli
    January 2006 8 1
    Danielle Blouin, Luigi Eugene Dagnone, Robert McGraw

    Objectives: In 2004, the format of the Royal College of Physicians and Surgeons of Canada certification exam in Emergency Medicine was modified to include an audiovisual session. Residents' performance on such stimuli is unknown. This study aims to determine the performance of Emergency Medicine postgraduate year 5 (PGY-5) on a novel practice examination using visual stimuli, in an effort to guide residents' preparatory study, and to help educators focus the teaching related to visual stimuli.
    Methods: In this prospective observational study, 30 PGY-5 residents from 12 Emergency Medicine programs across Canada participated in a practice examination in which they had to answer 133 questions related to 80 visual stimuli. The stimuli included electrocardiograms, medical imaging and clinical photographs. Three experienced faculty provided "reference standard" answers for the visual stimuli. For analysis purpose, stimuli were classified into 9 clinical domains, outlined in The Model of the Clinical Practice of Emergency Medicine.
    Results: Insufficient question numbers in 3 domains prevented reliable inferences. Correct answers were given for 65% of remaining questions, with the following domain distribution: 69% respiratory, 64% trauma, 73% cardiovascular, 62% head–eyes–ears–nose–throat (HEENT), 63% musculoskeletal and 69% cutaneous. Seventy-four percent of ECGs, 64% of imaging, and 62% of photograph-related questions were answered correctly. Incorrect answers were related to a lack of knowledge as well as imprecise or incomplete responses.
    Conclusions: PGY-5 subjects scored lowest in the HEENT and musculoskeletal domains. Medical educators should emphasize these domains in their teaching, and insist on precision and completeness of answers.

  • The trainee in difficulty
    July 2001 3 3
    Robert McGraw, Sarita Verma

    The trainee in difficulty is someone who is either marginal or at risk of failing in his or her clinical performance. Dealing effectively with these learners can pose problems even for seasoned medical educators. This article discusses some of the common mistakes made by educators in dealing with the trainee in difficulty and offers suggestions for a systematic approach. Further, the roles of faculty, including the program director and associate dean's office, and some of the legal issues are described.

  • Clinical diagnosis of clavicle fractures: a pilot study
    April 2001 3 2
    Jim Landine, Robert McGraw, William Pickett

    Objective: Clavicle fractures are commonly encountered in the emergency department (ED). Our objective was to determine whether emergency physicians can clinically predict the presence and location of a clavicle fracture prior to obtaining x-rays.
    Methods: Over a 16-month period we prospectively studied ED patients who had injuries compatible with a clavicle fracture. Following clinical examination and prior to obtaining radiographs, ED physicians or senior emergency medicine (EM) residents were asked to predict whether the clavicle was fractured and, if fractured, the location of the fracture. Clinical predictions were later compared to the radiologist's report.
    Results: Between April 1999 and August 2000, 184 patients with possible clavicle fracture were seen and 106 (58%) were enrolled. Of these, 94 had an acute fracture, and all 94 fractures were predicted on clinical grounds prior to x-ray. In 6 cases, physicians predicted a fracture but the radiograph was negative. In 6 additional cases, physicians were clinically unsure and the radiograph was negative. Physicians correctly predicted fracture location in 83 of 94 cases (88%; 95% confidence interval [CI], 82%-95%). In the 64 cases where physicians predicted a middle third fracture, they were 100% accurate (95% CI, 95%-100%). Errors made by physicians were conservative; that is, they occasionally predicted fractures in patients with only soft tissue injury, but they did not "miss" existing fractures.
    Conclusions: The results of this pilot study suggest that ED physicians can clinically predict the presence and location of clavicle fractures with a high degree of accuracy. It may be that x-rays are not always necessary in patients suspected of having a clavicle fracture. Future studies should define the indications for diagnostic radiography in patients with suspected clavicle fractures.
