There is no consensus on the optimal management of recent-onset episodes of atrial fibrillation or flutter. The approach to these conditions is particularly relevant in the current era of emergency department (ED) overcrowding. We sought to examine the effectiveness and safety of the Ottawa Aggressive Protocol to perform rapid cardioversion and discharge patients with these arrhythmias.

This cohort study enrolled consecutive patient visits to an adult university hospital ED for recent-onset atrial fibrillation or flutter managed with the Ottawa Aggressive Protocol. The protocol includes intravenous chemical cardioversion, electrical cardioversion if necessary and discharge home from the ED.

A total of 660 patient visits were included, 95.2% involving atrial fibrillation and 4.9% involving atrial flutter. The mean age of patients enrolled was 64.5 years. In total, 96.8% were discharged home and, of those, 93.3% were in sinus rhythm. All patients were initially administered intravenous procaïnamide, with a 58.3% conversion rate. A total of 243 patients underwent subsequent electrical cardioversion with a 91.7% success rate. Adverse events occurred in 7.6% of cases: hypotension 6.7%, bradycardia 0.3% and 7-day relapse 8.6%. There were no cases of torsades de pointes, stroke or death. The median lengths of stay in the ED were as follows: 4.9 hours overall, 3.9 hours for those undergoing conversion with procaïnamide and 6.5 hours for those requiring electrical conversion.

This is the largest study to date to evaluate the Ottawa Aggressive Protocol, a unique approach to cardioversion for ED patients with recent-onset episodes of atrial fibrillation and flutter. Our data demonstrate that the Ottawa Aggressive Protocol is effective, safe and rapid, and has the potential to significantly reduce hospital admissions and expedite ED care.

Our primary objective was to determine the effectiveness of 3 immobilization methods (circumferential casting [CC], volar–dorsal splinting [VDS] and modified sugar-tong [MST] splinting) in maintaining the position of displaced distal radius fractures after successful closed reduction. Our secondary objective was to assess long-term functional outcomes associated with immobilization with fibreglass splinting versus standard CC in patients maintaining initial nonoperative reductions.

We conducted a prospective randomized single-blind controlled trial in patients over 18 years of age who presented to the emergency department with a displaced fracture of the distal radius requiring closed reduction. The primary outcome was loss of reduction (defined as radiologic slippage or the need for surgical fixation during the 3–4 week primary immobilization period after initial successful reduction). Secondary outcomes included DASH (disabilities of the arm, shoulder and hand) score, return to work, activities of daily living, wrist pain, range of motion and grip strength assessed at 8 weeks and 6 months.

Thirty participants were randomly assigned to receive MST splinting, 31 to receive VDS and 40 to receive CC. Baseline characteristics were similar among groups. Radiographic loss of reduction occurred in 16% (95% confidence interval [CI] 3.1%–28.9%) of participants in the VDS group, 20% (95% CI 7.6%–32.4%) in the CC group and 30% (95% CI 13.6°%–46.4°%) in the MST splinting group (p = 0.17). Based on multivariate analysis of variance, functional outcomes at 8 weeks were similar among groups (p = 0.89). DASH scores at 8 weeks and 6 months were similar among groups, based on 1-way analysis of variance (p > 0.25).

Rates of loss in anatomic position were not statistically significant among the 3 types of dressings used. However, there was a clinically important trend of increased loss of reduction with the use of MST splinting. Functional outcomes at 8 weeks and 6 months were not significantly different between CC, VDS and MDS splinting. Ease of application and familiarity with use should guide clinical decisions when choosing a dressing type for displaced Colles fractures.

Computed tomography (CT) is an imaging modality used to detect renal stones. However, there is concern about the lifetime cumulative radiation exposure attributed to CT. Ultrasonography (US) has been used to diagnose urolithiasis, thereby avoiding radiation exposure. The objective of this study was to determine the ability of US to identify renal colic patients with a low risk of requiring urologic intervention within 90 days of their initial emergency department (ED) visit.

We completed a retrospective medical record review for all adult patients who underwent ED-ordered renal US for suspected urolithiasis over a 1-year period. Independent, double data extraction was performed for all imaging reports and US results were categorized as “normal,” “suggestive of ureterolithiasis,” “ureteric stone seen” or “disease unrelated to urolithiasis.” Charts were reviewed to determine how many patients underwent subsequent CT and urologic intervention.

Of the 817 renal US procedures ordered for suspected urolithiasis during the study period, the results of 352 (43.2%) were classified as normal, and only 2 (0.6%) of these patients required urologic intervention. The results of 177 (21.7%) renal US procedures were suggestive of ureterolithiasis. Of these, 12 (6.8%) patients required urologic intervention. Of the 241 (29.5%) patients who had a ureteric stone seen on US, 15 (6.2%) required urologic intervention. The rate of urologic intervention was significantly lower in those with normal results on US (p < 0.001) than in those with abnormal results on US.

A normal result on renal US predicts a low likelihood for urologic intervention within 90 days for adult ED patients with suspected urolithiasis.

The Joint Commission on Accreditation of Healthcare Organizations recommends that patients admitted to hospital with pneumonia receive their first dose of antibiotics within 6 hours of presenting to the emergency department (ED). Previous research in the United States indicates that rural hospitals may be better at achieving this benchmark than urban centres. This particular quality indicator has not yet been evaluated in Canada. The purpose of this study was to determine whether the target door-to-antibiotic (DTA) time of 6 hours or less could be met in a rural ED.

We conducted a retrospective chart review of patients admitted to hospital with a diagnosis of pneumonia. Descriptive data for each case was collected, including demographic and timeline information. We analyzed DTA time, antibiotic type, route of administration, hospital length of stay and disposition at discharge.

We reviewed a total of 320 charts from Apr. 1, 2003, to Mar. 31, 2008. The final sample consisted of 143 patients (50.3% women) whose median age was 79 years. The median DTA time was 151 minutes and 81.8% of patients received their first dose of antibiotics within 6 hours. Patients received antibiotics either orally (47.6%), intravenously (47.6%) or both (4.8%). Single-agent respiratory fluoroquinolones were used 71.4% of the time. Median length of hospital stay was 4 days; most patients were discharged home (79.7%), 11 died, 11 were transferred and 7 were discharged to a nursing home.

A DTA time of 6 hours or less is achievable in a rural ED.

Emergency medicine is an evolving discipline in Canadian medical schools. Little has been published regarding student preferences for emergency medicine training during the clerkship phase of MD programs. We assessed medical students' perceptions of a newly developed emergency medicine clerkship rotation involving multiple learning modalities. The evaluation process included assessment of the rotation's instructional elements and overall educational value.

The first cohort of medical students to complete this new emergency medicine clerkship was invited to answer a questionnaire just before graduation. Students rated their preferences for components of the rotation using paired comparisons. Open-ended questions explored students' satisfaction with the emergency medicine clerkship as well as perceptions of the rotation's impact on career development.

Of the 94 students in the first clerkship cohort, 81 (86%) responded to the survey. Students found the emergency medicine clerkship highly valuable, citing the broad range of cases seen, close supervision, and opportunities to develop clinical assessment, decision-making and procedural skills. Students' curricular preferences were for advanced cardiac life support (ACLS) (26.4%), clinical shifts (20.6%), supervised clinical shifts (17.8%), procedural skills laboratories (14.8%), tutorials (10.8%) and preceptor-assisted learning sessions (9.8%).

This new emergency medicine clerkship program incorporated multiple learning methods within a 4-week rotation and was highly rated by students. Although clinical shifts and ACLS were generally preferred activities, students had varying individual preferences for specific learning activities. Multiple learning methods allowed all students to benefit from the rotation. This study makes a compelling case for including an emergency medicine rotation with multiple learning modalities as a core element of clerkship at every medical school.
