Objectives: To determine if a dedicated teaching attending for medical student education improves medical student, attending physician, and resident perceptions and satisfaction.
Methods: Two dedicated teaching attending physician shifts were added to the clinical schedule each week. A before-after trial compared medical student evaluations from 2000 to 2004 (preteaching attending physician) to medical student evaluations from 2005 to 2006 (teaching attending physician). Attending physician and resident perceptions and satisfaction with the teaching attending physician shifts using a 5-point Likert-type scale (1 = poor to 5 = excellent) were also assessed.
Results: Eighty-nine (100%) medical students participated, with 63 preteaching attending physician and 26 teaching attending physician rotation evaluations. The addition of teaching attending physician shifts improved mean medical student satisfaction with bedside teaching (4.1 to 4.5), lecture satisfaction (4.2 to 4.8), preceptor scores (4.3 to 4.8), and perceived usefulness of the rotation (4.5 to 5.0) (all p < 0.05). Thirteen attending physicians (93%) participated in the cross-sectional questionnaire. The addition of teaching attending physician shifts improved faculty ratings of their medical student interactions by ≥ 1.5 points for all items (p ≤ 0.001). Faculty perceptions of their resident interactions improved for quality of bedside teaching (3.1 to 4.0), their availability to hear resident presentations (3.4 to 4.2), and their supervision of residents (3.4 to 4.1) (p ≤ 0.01). Residents (n = 35) noted minor improvements with the timeliness of patient dispositions, faculty bedside teaching, and attending physician availability.
Conclusions:The addition of select teaching attending physician shifts had the greatest effect on medical student and faculty perceptions and satisfaction, with some improvements for residents.

Objective: Numerous barriers to maintaining infection control practices through the use of personal protective equipment (PPE) exist in the emergency department (ED). This study examined the knowledge, self-reported behaviours, and barriers to compliance with infection control practices and the use of PPE in Canadian pediatric EDs.
Methods: A self-administered survey instrument consisting of 21 questions was developed and piloted for this study. The survey was mailed to all individuals listed in the Pediatric Emergency Research Canada database of physicians practicing pediatric emergency medicine in Canada.
Results: A total of 186 physicians were surveyed, and 123 (66%) participated. Twenty-two percent of participants reported that they had never received PPE training and 32% had not been trained in the previous 2 years. Fifty-three percent reported being very or somewhat comfortable with their knowledge of transmission-based isolation practices. Participants were correct on a mean of 4.9 of 11 knowledge-based questions (SD 1.7). For scenarios assessing self-reported use of PPE, participants selected answers that reflected PPE use in accordance with national infection control standards in a mean of 1.0 of 6 scenarios (SD 1.0). Participants reported that they would be more likely to use PPE if patients were clearly identified prior to physician assessment, equipment was accessible, and PPE use was made a priority in their ED.
Conclusions: Knowledge and self-reported adherence to recommended infection control practices among Canadian pediatric emergency physicians is suboptimal. Early identification of patients requiring PPE, convenient access to PPE, and improved education regarding isolation and PPE practices may improve adherence.

Objective: Chronic obstructive pulmonary disease (COPD) is a widespread illness with an increasing prevalence in older adults; exacerbations resulting in visits to the emergency department (ED) are common. We sought to determine the epidemiology of COPD presentations to EDs by older adults in Alberta.

Methods: Administrative databases were used to examine all ED encounters for COPD from April 1999 to March 2005 in Alberta. Data included demographics of patients and timing of ED visits. Data analysis included descriptive summaries and age–sex directly standardized visit rates (DSVRs).

Results: There were 85 330 ED visits for acute COPD made by 38 638 patients 55 years of age or older during the study period. More men (53.2%) presented, and the mean age at presentation was 72 years. The age–sex DSVRs remained stable from 2000/01 (24.4/1000) to 2004/05 (25.6/1000). Presentation rates differed among population subgroups. Overall, 67% of visits resulted in discharge from the ED.

Conclusion: Chronic obstructive pulmonary disease is a common presentation in Alberta EDs; however, the rates of presentation were stable during the study period, and monthly and hourly trends exhibited similar patterns for each year. Disparities based on age, sex, and socio-economic and cultural statuses were identified. Targeted interventions could be implemented to reduce future ED visits for COPD.
