Objectives To evaluate the utility of universal psychosocial screening in the emergency department (ED) using MyHEARTSMAP, a digital self-assessment and management guiding tool. Study design We conducted a cohort study of youth 10-17 years of age with nonmental health related presentations at 2 pediatric EDs. On randomly selected shifts (December 2017-February 2019), participants completed their psychosocial self-assessments using MyHEARTSMAP on a mobile device, then underwent a standardized clinical mental health assessment (criterion standard). We reported the sensitivity and specificity of respondents' self-assessment, against a clinician's standard emergency psychosocial assessment, and the frequency of psychosocial issues and recommended mental health resources identified by screening. Results We approached 1432 eligible youth, among which 795 youth consented to participate (55.5%). Youth and guardians' sensitivity at self-identifying psychiatric concerns was 92.7% (95% CI 89.1, 95.4%) and 93.1% (95% CI 89.5, 95.8%), respectively. In cases where clinicians had determined to be no psychiatric issues, 98.5% (95% CI 96.7, 99.4%) of youth and 98.9% (95% CI 97.3, 99.7%) of guardians identified the youth as having no or only mild issues. Screening identified 36.4% of youth as having issues in at least 1 psychosocial domain which warranted further follow-up. Conclusions Psychosocial screening in EDs using MyHEARTSMAP can reliably be conducted using the MyHEARTSMAP self-assessment tool and over one-third of screened youth identified issues which can be directed to further care.

OBJECTIVES: The objective of this study was to estimate the seroprevalence of HIV infection and the acceptability of point-of-care HIV testing in an innercity Canadian emergency department. METHODS: We conducted a prospective cohort study in an urban tertiary care emergency department between August 2009 and January 2011. Randomly selected patients were enrolled using probabilistic sampling based on patient volumes. Inclusion criteria were age 19–75 years and ability to provide informed consent. Patients who were intoxicated or in extremis were excluded. After informed consent and brief pre-test counselling, participants’ HIV status was obtained using the INSTI HIV-1/HIV-2 Antibody Test. Participants completed a questionnaire on HIV risk behaviours and satisfaction with emergency department HIV testing. Participants with a positive result or those having other blood tests received confirmatory Western blot testing. HIV-positive participants were offered immediate referral to an HIV specialty clinic. RESULTS: A total of 2,077 patients were approached, and 1,402 (67.5%) agreed to participate. Participants’ mean age was 43.3 years, and 58.4% of participants were male. The HIV antibody seroprevalence based on the point-of-care test was 65/1,402 (4.6%; 95% confidence interval: 3.5%–5.8%). No new diagnoses of HIV were identified in our cohort. Patient satisfaction with point-of-care HIV testing was high (mean satisfaction score 9.6/10). CONCLUSION: On the basis of a rapid, point-of-care HIV antibody test, the seroprevalence rate of HIV in an inner city emergency department was 4.6%. Point-of-care testing in the emergency department is acceptable, and patients’ satisfaction with the testing procedure was high.

Background Moxifloxacin can be used in the treatment of tuberculosis, its effect on the diagnosis and treatment of pulmonary tuberculosis is not well characterized. Objective To identify patients from the St. Paul's Hospital emergency department (ED) treated with moxifloxacin who also had sputum sent for investigation of possible tuberculosis and the impact on sensitivity of acid-fast bacilli (AFB) smears and time to initiation of tuberculosis treatment. Methods We conducted a retrospective single-center cohort study on patients that were prescribed moxifloxacin in the ED during a 5-year period and had samples collected for pulmonary tuberculosis. All AFB samples obtained throughout the hospital in patients not exposed to moxifloxacin during the same time period were also examined. Results Two-thousand six hundred and seventy-three patients who were admitted to St. Paul's Hospital through the ED received moxifloxacin during the study period. 273 (10.2%) of these patients were subsequently investigated for tuberculosis, with 9 positive cases of Mycobacterium tuberculosis (3.3%). One-thousand three hundred and sixty-nine patients not exposed to moxifloxacin were screened for tuberculosis with 33 active cases (2.4%). The false-negative rate for AFB smears in the exposed group was 85.2% vs. 53.8% in the unexposed group (relative risk of false-negative AFB = 1.55; 95% CI 1.24–2.03). Time to initiation of anti-tuberculosis therapy was significantly delayed in the exposed group, with median time to initiation of 14 days vs. 2 days (p = 0.013). Conclusions Exposure to moxifloxacin is associated with significantly increased rates of false-negative AFB smears and was associated with a significant delay in the initiation of anti-tuberculosis therapy.

ObjectivesAlthough procedural sedation for cardioversion is a common event in emergency departments (EDs), there is limited evidence surrounding medication choices. We sought to evaluate geographic and temporal variation in sedative choice at multiple Canadian sites, and to estimate the risk of adverse events due to sedative choice.MethodsThis is a secondary analysis of one health records review, the Recent Onset Atrial Fibrillation or Flutter-0 (RAFF-0 [n=420, 2008]) and one prospective cohort study, the Recent Onset Atrial Fibrillation or Flutter-1 (RAFF-1 [n=565, 2010 – 2012]) at eight and six Canadian EDs, respectively. Sedative choices within and among EDs were quantified, and the risk of adverse events was examined with adjusted and unadjusted comparisons of sedative regimes.ResultsIn RAFF-0 and RAFF-1, the combination of propofol and fentanyl was most popular (63.8% and 52.7%) followed by propofol alone (27.9% and 37.3%). There were substantially more adverse events in the RAFF-0 data set (13.5%) versus RAFF-1 (3.3%). In both data sets, the combination of propofol/fentanyl was not associated with increased adverse event risk compared to propofol alone.ConclusionThere is marked variability in procedural sedation medication choice for a direct current cardioversion in Canadian EDs, with increased use of propofol alone as a sedation agent over time. The risk of adverse events from procedural sedation during cardioversion is low but not insignificant. We did not identify an increased risk of adverse events with the addition of fentanyl as an adjunctive analgesic to propofol.

Objective: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.Methods: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.Results: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).Conclusion: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.

Objective:It is believed that when patients present to the emergency department (ED) with recent-onset atrial fibrillation or flutter (RAFF), controlling the ventricular rate before cardioversion improves the success rate. We evaluated the influence of rate control medication and other variables on the success of cardioversion.Methods:This secondary analysis of a medical records review comprised 1,068 patients with RAFF who presented to eight Canadian EDs over 12 months. Univariate analysis was performed to find associations between predictors of conversion to sinus rhythm including use of rate control, rhythm control, and other variables. Predictive variables were incorporated into the multivariate model to calculate adjusted odds ratios (ORs) associated with successful cardioversion.Results:A total of 634 patients underwent attempted cardioversion: 428 electrical, 354 chemical, and 148 both. Adjusted ORs for factors associated with successful electrical cardioversion were use of rate control medication, 0.39 (95% confidence interval [CI] 0.21-0.74); rhythm control medication, 0.28 (95% CI 0.15-0.53); and CHADS2score > 0, 0.43 (95% CI 0.15-0.83). ORs for factors associated with successful chemical cardioversion were use of rate control medication, 1.29 (95% CI 0.82-2.03); female sex, 2.37 (95% CI 1.50-3.72); and use of procainamide, 2.32 (95% CI 1.43-3.74).Conclusion:We demonstrated reduced successful electrical cardioversion of RAFF when patients were pretreated with either rate or rhythm control medication. Although rate control medication was not associated with increased success of chemical cardioversion, use of procainamide was. Slowing the ventricular rate prior to cardioversion should be avoided.

Study objective Atrial fibrillation is the most common dysrhythmia observed in the emergency department (ED), yet there is little research describing long-term outcomes after ED management. Our objective is to describe ED treatment approach, conversion success rates, ED adverse events, and 30-day and 1-year outcomes for a cohort of ED patients with atrial fibrillation and no acute underlying medical cause. Methods This retrospective cohort study used a database from 2 urban EDs to identify consecutive patients with an ED discharge diagnosis of atrial fibrillation from April 1, 2006, to March 31, 2010. Comorbidities, rhythms, management, and immediate outcomes were obtained by manual chart review, and patients with an acute underlying medical condition were excluded by predefined criteria. Patients were stratified into 5 groups according to ED management: electrocardioversion, chemical cardioversion, spontaneous cardioversion, rate control only, and no arrhythmia-specific treatment. To identify deaths, strokes, and ED revisits within 1 year, each patient's unique provincial health number was linked to the provincial vital statistics registry and the regional ED database. Primary outcome was the number of patients having either stroke or death of any cause at 30 days, stratified by treatment group. Results Of 927 consecutive eligible patients, 121 (13.1%) converted to sinus rhythm before ED intervention, 357 (38.5%) received ED rhythm control, and 449 (48.4%) did not receive rhythm control. Overall, 142 of 927 patients (15.3%) were admitted to the hospital at the index ED visit. At 30 days, 2 patients had a stroke and 5 died (combined outcome rate 0.8%; 95% confidence interval 0.3% to 1.6%). All 7 of these patients were admitted at the index ED visit. Conclusion In this large cohort of ED patients with atrial fibrillation and no acute underlying medical cause, the 30-day rate for stroke or death was less than 1%. Nearly 85% of patients—regardless of treatment approach or conversion to sinus rhythm—were discharged at the index ED visit, and none of these patients had a stroke or died at 30 days.

Objectives Increases in regional emergency department (ED) efficiencies might be obtained by shifting patients to less crowded EDs. The authors sought to determine factors associated with a patient's decision to choose a specific regional ED. Based on prior focus group discussions with volunteers, the hypothesis was that distance to a specific ED and perceived ED wait times would be important. Methods A cross-sectional survey was developed using qualitative focus group methodology. The resulting survey was composed of 17 questions relating to patient decisions in choosing a specific ED and was administered in each of six EDs in a single urban Canadian health region at all hours of the day. Ambulatory patients with a Canadian Triage and Acuity Scale (CTAS) level 3 to 5 and aged ≥19 years were surveyed. The primary outcome was the proportion of patients whose main motivation for attending a specific ED was either distance traveled to reach the ED or perceived ED waiting time. Multivariable logistic regression was performed to assess factors influencing both of these reasons. Results A total of 757 patients were approached and 634 surveys (83.8%) were completed. Distance from the ED (named by 44.0% of respondents as their primary reason) and perceived ED wait times (9.3%) were the main motivations for patients to attend a specific ED. Multivariable analysis of factors associated with choosing distance revealed that ED distance

While a substantial literature exists demonstrating a strong association of alcohol and intentional injury, less is known about the association of intentional injury with recreational drug use, either alone, or in combination with alcohol.The risk of intentional injury due to alcohol and other drug use prior to injury is analyzed in a sample of emergency department (ED) patients.Logistic regression was used to examine the predictive value of alcohol and drug use on intentional versus non-intentional injury in a probability sample of ED patients in Vancouver, BC (n = 436).Those reporting only alcohol use were close to four times more likely (OR = 3.73) to report an intentional injury, and those reporting alcohol combined with other drug(s) almost 18 times more likely (OR = 17.75) than those reporting no substance use. Those reporting both alcohol and drug use reported drinking significantly more alcohol (15.7 drinks) than those reporting alcohol use alone (5 drinks).These data suggest that alcohol in combination with other drugs may be more strongly associated with intentional injury than alcohol alone.The strong association of alcohol combined with other drug use on injury may be due to the increased amount of alcohol consumed by those using both substances, and is an area requiring more research with larger samples of intentional injury patients.

Study objective Although recent-onset atrial fibrillation and flutter are common arrhythmias managed in the emergency department (ED), there is insufficient evidence to help physicians choose between 2 competing treatment strategies, rate control and rhythm control. We seek to evaluate variation in ED management practices for recent-onset atrial fibrillation and flutter patients at multiple Canadian sites and to determine whether hospital site was an independent predictor of attempted cardioversion. Methods We conducted a cross-sectional survey by health records review on an observational cohort of all eligible adult recent-onset atrial fibrillation and flutter cases, with onset of symptoms less than 48 hours, treated at 8 academic hospital EDs during a 12-month period, and evaluated the variation in practice among sites for important management strategies. Results Among the 1,068 study patients, 88.3% had atrial fibrillation and 11.7% had atrial flutter. The proportion of cases managed with rhythm control was 59.4% (interhospital range 42% to 85%) and, among these, electrocardioversion was attempted first for 44.2% (range 7% to 69%). There was variation in most management strategies, including use of rate control drugs 54.9% (range 37% to 65%), choice of procainamide as rhythm control drug 62.1% (range 15% to 89%), referral to cardiology in the ED 30.7% (range 16% to 64%), use of heparin 13.7% (range 1% to 29%), and outpatient cardiology referral 43.0% (range 30% to 65%). Adverse events were relatively uncommon and transient for patients undergoing attempts at pharmacologic (13.0%) or electrocardioversion (12.1%). Overall, 83.3% of patients were discharged home from the ED (range 73% to 90%). After controlling for 12 covariates, multivariate logistic regression found that factors independently associated with attempted cardioversion were age (odds ratio [OR] 0.97; 95% confidence interval [CI] 0.95 to 0.98), history of electrocardioversion (OR 2.73; 95% CI 1.56 to 4.80), associated heart failure (OR 0.29; 95% CI 0.09 to 0.95), and hospital site (ORs ranged from 0.38 to 3.05). Conclusion We demonstrated a high degree of variation in management approaches for recent-onset atrial fibrillation and flutter patients treated in academic hospital EDs. Individual hospital site, age, previous cardioversion, and associated heart failure were independent predictors for the use of rhythm control.
