RESUMEN
OBJECTIVES: To assess the comparative effectiveness and safety of parenteral agents for pain reduction in patients with acute migraine. BACKGROUND: Parenteral agents have been shown to be effective in treating acute migraine pain; however, the comparative effectiveness of different approaches is unclear. METHODS: Nine electronic databases and gray literature sources were searched to identify randomized clinical trials assessing parenteral agents to treat acute migraine pain in emergency settings. Two independent reviewers completed study screening, data extraction, and Cochrane risk-of-bias assessment, with differences being resolved by adjudication. The protocol of the review was registered with the International Prospective Register of Systematic Reviews (PROSPERO; CRD42018100096). RESULTS: A total of 97 unique studies were included, with most studies reporting a high or unclear risk of bias. Monotherapy, as well as combination therapy, successfully reduced pain scores prior to discharge. They also increased the proportion of patients reporting pain relief and being pain free. Across the pain outcomes assessed, combination therapy was one of the higher ranked approaches and provided robust improvements in pain outcomes, including lowering pain scores (mean difference -3.36, 95% confidence interval [CI] -4.64 to -2.08) and increasing the proportion of patients reporting pain relief (risk ratio [RR] 2.83, 95% CI 1.74-4.61). Neuroleptics and metoclopramide also ranked high in terms of the proportion of patients reporting pain relief (neuroleptics RR 2.76, 95% CI 2.12-3.60; metoclopramide RR 2.58, 95% CI 1.90-3.49) and being pain free before emergency department discharge (neuroleptics RR 4.8, 95% CI 3.61-6.49; metoclopramide RR 4.1, 95% CI 3.02-5.44). Most parenteral agents were associated with increased adverse events, particularly combination therapy and neuroleptics. CONCLUSIONS: Various parenteral agents were found to provide effective pain relief. Considering the consistent improvements across various outcomes, combination therapy, as well as monotherapy of either metoclopramide or neuroleptics are recommended as first-line options for managing acute migraine pain. There are risks of adverse events, especially akathisia, following treatment with these agents. We recommend that a shared decision-making model be considered to effectively identify the best treatment option based on the patient's needs.

OBJECTIVE: Management of primary headache (PHA) varies across emergency departments (ED), yet there is widespread agreement that computed tomography (CT) scans are overused. This study assessed emergency physicians' (EPs) PHA management and their attitudes towards head CT ordering. METHODS: A cross-sectional study was undertaken with EPs from one Canadian center. Drivers of physicians' perceptions regarding the appropriateness of CT ordering for patients with PHA were explored. RESULTS: A total of 73 EPs (70% males; 48% with <10 years of practice) participated in the study. Most EPs (88%) did not order investigations for moderate-severe primary headaches; however, CT was the common investigation (47%) for headaches that did not improve. Computed tomography ordering was frequently motivated by the need for specialist consultation (64%) or admission (64%). A small proportion (27%) believed patients usually/frequently expected a scan. Nearly half of EPs (48%) identified patient imaging expectations/requests as a barrier to reducing CT ordering. Emergency physicians with CCFP (EM) certification were less likely to perceive CT ordering for patients with PHA as appropriate. Conversely, those who identified the possibility of missing a condition as a major barrier to limiting their CT use were more likely to perceive CT ordering for patients with PHA as appropriate. CONCLUSIONS: Emergency physicians reported consistency and evidence-based medical management. They highlighted the complexities of limiting CT ordering and both their level of training and their perceived barriers for limiting CT ordering seem to be influencing their attitudes. Further studies could elucidate these and other factors influencing their practice.
RESUMEN
OBJECTIVE: This systematic review aimed to identify research involving adults presenting to the emergency department (ED) with a concussion to document the reporting of sex and/or gender according to the Canadian Institutes of Health Research (CIHR) guidelines, the prevalence of sex and gender-based analysis (SGBA) and to summarise sex and/or gender-based differences in ED presentation, management and outcomes. DESIGN: Systematic review. METHODS: Electronic databases and grey literature were searched to identify studies that recruited adult patients with concussion from the ED. Two independent reviewers identified eligible studies, assessed quality and extracted data. A descriptive summary of the evidence was generated, and sex and/or gender reporting was examined for accuracy according to standardised criteria. RESULTS: Overall, 126 studies were included in the analyses. A total of 80 (64%) studies reported sex and/or gender as demographic information, of which 51 (64%) included sex and/or gender in their analysis; however, 2 (3%) studies focused on an SGBA. Sex was more accurately reported in alignment with CIHR definitions than gender (94% vs 12%; p<0.0001). In total, 25 studies used an SGBA for outcomes of interest. Males and females experience different causes of concussion, 60% of studies documented that females had less frequent CT scanning while in the ED, and 57% of studies reported that postconcussion syndrome was more prevalent in females and women. CONCLUSION: This systematic review highlighted that sex is reported more accurately than gender, approximately half of studies did not report either sex and/or gender as demographic information, and one-third of studies did not include SGBA. There were important sex and gender differences in the cause, ED presentation, management and outcomes of concussions. PROSPERO REGISTRATION NUMBER: CRD42021258613.

OBJECTIVES: Adjunct therapy with anticholinergic agents has been proposed to reduce the incidence of extrapyramidal side effects such as akathisia following treatment with neuroleptics or metoclopramide. This systematic review assessed the effectiveness of anticholinergic agents to prevent neuroleptic or metoclopramide-induced akathisia in patients presenting to the emergency department (ED) with benign headache. METHODS: Eight electronic databases and the gray literature were searched to identify randomized controlled trials involving adult patients presenting to the ED with primary headache treated with neuroleptic or metoclopramide. Study selection, data extraction, and quality assessment were completed by two independent reviewers. Individual or pooled meta-analysis of dichotomous outcomes were calculated as relative risks (RRs) with 95% confidence intervals (CIs) using a random-effects model. Heterogeneity was assessed using the I2 statistic. RESULTS: A total of 1032 studies were screened, of which two studies were included in the review. Both studies provided patients with diphenhydramine following treatment with neuroleptics or metoclopramide. Treatment with diphenhydramine did not reduce the incidence of akathisia compared to treatment with placebo (RR 0.83, 95% CI 0.43-1.61, I2 = 0%). The impact of diphenhydramine on pain relief, need for rescue medications, and relief of other extrapyramidal side effects was reported in one of the two studies, with no significant differences noted in any outcomes compared to patients treated with placebo. CONCLUSION: This review found insufficient evidence to recommend the use of diphenhydramine as an adjunct therapy to prevent akathisia in ED patients treated with neuroleptics or metoclopramide for primary headache. This finding relies on the results of two small randomized controlled trials with incomplete outcome reporting. Additional high-quality studies are needed to better understand the clinical efficacy of agents with anticholinergic properties in the ED management of patients with primary headaches.

OBJECTIVE: To document the occurrence and recovery outcomes of sports-related concussions (SRCs) presenting to the Emergency Department (ED) in a community-based sample. DESIGN: A prospective observational cohort study was conducted in 3 Canadian hospitals. SETTING: Emergency Department. PATIENTS: Adults (≥17 years) presenting with a concussion to participating EDs with a Glasgow Coma Scale score ≥13 were recruited. INTERVENTIONS: Patient demographics (eg, age and sex), clinical characteristics (eg, history of depression or anxiety), injury characteristics (eg, injury mechanisms and loss of consciousness and duration), and ED management and outcomes (eg, imaging, consultations, and ED length of stay) were collected. MAIN OUTCOME MEASURES: Patients' self-reported persistent concussion symptoms, return to physical activity status, and health-related quality of life at 30 and 90 days after ED discharge. RESULTS: Overall, 248 patients were enrolled, and 25% had a SRC. Patients with SRCs were younger and reported more physical activity before the event. Although most of the patients with SRCs returned to their normal physical activities at 30 days, postconcussive symptoms persisted in 40% at 90 days of follow-up. After adjustment, there was no significant association between SRCs and persistent symptoms; however, patients with concussion from motor vehicle collisions were more likely to have persistent symptoms. CONCLUSION: Although physically active individuals may recover faster after a concussion, patients returning to their physical activities before full resolution of symptoms are at higher risk of persistent symptoms and further injury. Patient-clinician communications and tailored recommendations should be encouraged to guide appropriate acute management of concussions.

OBJECTIVES: Emergency department (ED) consultations with specialists are necessary for safe and effective patient care. Delays in the ED consultation process, however, have been shown to increase ED length of stay (LOS) and contribute to ED crowding. This review aims to describe and evaluate the effectiveness of interventions to improve the ED consultation process. METHODS: Eight primary literature databases and the gray literature were searched to identify comparative studies assessing ED-based interventions to improve the specialist consultation process. Two independent reviewers identified eligible studies, assessed study quality, and extracted data. Individual or pooled meta-analysis for continuous outcomes were calculated as mean differences (MDs) with 95% confidence intervals (CIs) using a random-effects model was conducted. RESULTS: Thirty-five unique comparative intervention studies were included. While the interventions varied, four common components/themes were identified including interventions to improve consultant responsiveness (n = 11), improve access to consultants in the ED (n = 9), expedite ED consultations (n = 8), and bypass ED consultations (n = 7). Studies on interventions to improve consult responsiveness consistently reported a decrease in consult response times in the intervention group with percent changes between 10% and 71%. Studies implementing interventions to improve consult responsiveness (MD -2.55, 95% CI -4.88 to -0.22) and interventions to bypass ED consultations (MD -0.99, 95% CI -1.43 to -0.56) consistently reported a decrease in ED LOS; however, heterogeneity was high (I2 = 99%). Evidence on whether any of the interventions were effective at reducing the proportion of patients consulted or subsequently admitted varied. CONCLUSIONS: The various interventions impacting the consultation process were predominately successful in reducing ED LOS, with evidence suggesting that interventions improving consult responsiveness and improving access to consultants in the ED also improve consult response times. Health care providers looking to implement interventions to improve the ED consultation process should identify key areas in their setting that could be targeted.

Low back pain is a common presentation to emergency departments, but the reasons why people choose to attend the emergency department have not been explored. We aimed to fill this gap with this study to understand why persons with low back pain choose to attend the emergency department. Between July 4, 2017 and October 1, 2018, consecutive patients with a complaint of low back pain presenting to the University of Alberta Hospital emergency department were screened. Those enrolled completed a 13-item questionnaire to assess reasons and expectations related to their presentation. Demographics, acuity and disposition were obtained electronically. Factors associated with admission were examined in a logistic regression model. After screening 812 patients, 209 participants met the study criteria. The most common Canadian Triage and Acuity Scale score was 3 (73.2%). Overall, 37 (17.7%) received at least one consultation, 89.0% of participants were discharged home, 9.6% were admitted and 1.4% were transferred. Participants had a median pain intensity of 8/10 and a median daily functioning of 3/10. When asked, 64.6% attended for pain control while 44.5% stated ease of access. Most participants expected to obtain pain medication (67%) and advice (56%). Few attended because of cost savings (3.8%). After adjustment, only advanced age and ambulance arrival were significantly associated with admission. In conclusion, most low back pain patients came to the emergency department for pain control yet few were admitted and the majority did not receive a consultation. Timely alternatives for management of low back pain in the emergency department appear needed, yet are lacking.

OBJECTIVES: This systematic review identified and assessed psychometric properties of the available screening tools to identify patients with unmet palliative care (PC) needs in the emergency department (ED). METHODS: A comprehensive search of electronic databases and the gray literature was conducted. Two independent reviewers completed study screening and inclusion, data extraction, and quality assessment. A descriptive summary of the results was reported using median of medians and interquartile ranges (IQRs). RESULTS: A total of 35 studies were included, involving the assessment of 14 unique screening tools. The most commonly used screening tool was the surprise question (SQ; n = 12 studies), followed by the Palliative Care and Rapid Emergency Screening (P-CaRES) tool (n = 8), and the screening for palliative and end-of-life care needs in the emergency department (SPEED) instrument (n = 4). Twelve of the included studies reported on the psychometric properties of the screening tools, of which eight of these studies assessed the performance of the SQ to predict patient mortality. Overall, the median sensitivity (63%, IQR 38%-78%) and specificity (75%, IQR 57%-84%) of the SQ to predict mortality at 1 or 12 months was moderate. While the median positive predictive value of the SQ was low (32%, IQR 16%-40%), the median negative predictive value was high (91%, IQR 88%-95%). Across the studies, the proportion of patients identified as having unmet PC based on the criteria of the screening tools ranged from 5% to 83%. CONCLUSIONS: This review identified 14 unique screening tools used to identify adult patients with unmet PC needs in the ED. One screening tool, the SQ, was found to have moderate sensitivity and specificity to accurately predict future patient mortality. Additional research is needed to better understand the clinical value of this and the other available tools prior to their widespread implementation.

Background: An increasing number of patients with end-of-life (EOL) conditions, particularly those with advanced cancer, are presenting to the emergency department (ED). Objectives: To assess the characteristics, management and short-term outcomes of ED patients with advanced cancer compared to patients with other EOL conditions. Methodology/Design: A secondary analysis of a prospective cohort study. Setting/Participants: Volunteer emergency physicians in two Canadian EDs identified presentations for advanced cancer and other EOL conditions with the aid of a modified screening tool March-August 2018. Results: Among the 663 presentations by patients with EOL conditions, 272 (41%) presented with advanced cancer. The majority of presentations for advanced cancer (81%) or other EOL conditions (77%) were by patients with unmet palliative care (PC) needs. Patients with advanced cancer were significantly less likely to have active goals of care (GOC) documented on their charts (53% vs. 75%; p < 0.001). While no significant differences were found between the groups, the majority of presentations involved imaging, investigations, consultations, and hospitalization. Presentations for advanced cancer were more likely to receive a postdischarge referral (38% vs. 23%; p < 0.001). Referrals to PC consultations or postdischarge referrals were infrequent. Regression analysis found that patients with advanced cancer were associated with shorter length of stay (LOS). Conclusions: The majority of presentations for advanced cancer or other EOL conditions involved significant resource use. Patients with cancer experienced shorter LOS; however, had less documentation of GOC and gaps in referrals to PC services were identified. Interventions should be explored to promote early GOC discussions and PC referrals in this patient group.

INTRODUCTION: This study examined emergency department (ED) presentations of patients with end of life (EOL) conditions and patients having met and unmet palliative care needs were compared. METHODS: Presentations for EOL conditions were prospectively identified and screened for palliative care needs. Descriptive data were reported as proportions, means or medians. Bi-variable analysis for dichotomous and continuous variables were performed by chi-squared and T-tests (p≤0.01), respectively. A multivariable logistic regression model identified factors associated with having unmet palliative needs and reported adjusted odds ratios (aOR) with 95% confidence intervals (CI). RESULTS: Overall, 663 presentations for EOL conditions were identified; 518 (78%) involved patients with unmet palliative care needs. Presentations by patients with unmet palliative needs were more likely to involve consultations (80% vs. 67%, p = 0.001) and result in hospitalization (69% vs. 51%, p<0.001) compared to patients whose palliative needs were met. Patients with unmet palliative care needs were more likely to have previous ED visits (73% unmet vs. 48% met; p<0.001). While medication, procedures, investigations and imaging ordering were high across all patients with EOL conditions, there were no significant differences between the groups. Consultations with palliative specialists in the ED (6% unmet vs. 1% met) and following discharge (29% unmet vs. 18% met) were similarly uncommon. Patients having two or more EOL conditions (aOR = 2.41; 95% CI: 1.16, 5.00), requiring hospitalization (aOR = 1.93; 95% CI: 1.30, 2.87), and dying during the ED visit (aOR = 2.15; 95% CI: 1.02, 4.53) were strongly associated with having unmet palliative care needs. CONCLUSIONS: Most ED presentations for EOL conditions were made by patients with unmet palliative care needs, who were significantly more likely to require consultation, hospitalization, and to die. Referrals to palliative care services during and after the ED visit were infrequent, indicating important opportunities to promote these services.

Background: Presentations to the emergency department (ED) by patients with end-of-life (EOL) conditions for their acute care needs are common. Objectives: The objective of this study was to identify and describe the ED management across presentations to the ED for EOL conditions. Design: Prospective observational cohort study. Settings/Subjects: Emergency physicians in two Canadian ED's were asked to identify presentations by adult patients with EOL conditions using a modified screening tool. Measurements: Patient characteristics and ED management for each presentation were collected through chart review by trained research assistants. Descriptive analyses were conducted as appropriate and bivariate comparisons of dichotomous and continuous variables were completed using χ2 tests and using t test or Wilcoxon rank-sum test, respectively. Results: Physicians identified 663 ED presentations for EOL conditions, with advanced cancer (41%), dementia (23%), and chronic obstructive pulmonary disease (16%) being the most common EOL conditions. The majority of presentations involved consultations (77%), hospitalization (65%), and numerous investigations (97%), including blood work (97%) and imaging (92%). The majority of patients with EOL conditions had a history of ED visits (68%). Using a modified screening tool, 78% of presentations involved patients with unmet palliative care needs, but only 1% of presentations involved a palliative consultation or admission to a palliative care unit. Conclusion: Presentations to the ED for EOL conditions involve significant ED resources; however, only a handful of patients are referred to palliative services. Patients with EOL conditions are appropriate targets for palliative services and community support outside the ED.

Background and Objective: With the increase of visits among patients with end-of-life needs, palliative care (PC) interventions delivered in the emergency department (ED) have become increasingly important. The objective of this systematic review was to examine the effectiveness of ED-based PC interventions. Methods: A comprehensive search of the literature was conducted to identify any comparative studies assessing the effectiveness of ED-based PC interventions. Two independent reviewers completed study selection, quality assessment, and data extraction. Relative risks (RR) with 95% confidence intervals (CIs) were calculated using a random effects model and heterogeneity (I2) was reported. Results: A total of 18 unique studies were included. Two studies reported no difference in return visits to the ED (RR = 1.31; 95% CI: 0.73-2.35; I2 = 47%). Two randomized trials reported no difference in mortality (RR = 0.89; 95% CI: 0.71-1.13; I2 = 0%), while one cohort study reported an increased mortality among patients referred to PC in the ED (RR = 1.89; 95% CI: 1.58-2.27). Overall, six out of eight studies reported a decrease in hospital length of stay (LOS) among patients undergoing an ED-based PC intervention compared with usual care. Conclusions: While there is compelling evidence to suggest that ED-based PC interventions can reduce hospital LOS, the evidence for the impact of these interventions on other outcomes is less robust. More high-quality comparative studies are needed to better understand the overall impact of ED-based PC interventions on improving patient outcomes as well as improving throughput and other quality of service-related outcomes.

BACKGROUND: Dyspnea is a common symptom that has many causes, including obstructive airway disorders. We sought to examine previous diagnosis of obstructive airway disorders and other conditions in patients receiving treatment with inhaled medications for shortness of breath in a community setting. METHODS: This cross-sectional study included consecutive patients aged 18 years and older receiving treatment for shortness of breath with inhaled medications for a minimum of 6 months. Study participants were recruited through community pharmacies in Edmonton and Saskatoon, Canada, between February 2009 and February 2012. Previous diagnosis of obstructive airway disorders by a primary care provider was assessed by patient self-report and review of health records. We conducted an assessment (as per guidelines from the American Thoracic Society and the European Respiratory Society), including pulmonary function tests; diagnoses were adjudicated by an expert physician panel (2 respirologists and 1 emergency physician). The agreement between diagnoses derived from pulmonary function tests and diagnoses from primary care providers was evaluated. RESULTS: A total of 328 patients (median age 50 yr, 57.3% female) underwent assessment; 134 (40.9%) of patients reported ever having a pulmonary function test performed. After adjudication, 138 (42.1%) were diagnosed with asthma only, 86 (26.2%) with chronic obstructive pulmonary disease only and 11 (3.4%) with both. Some patients (93, 28.4%) had no evidence of obstructive airway disorders and 20 (6.1%) had evidence of other conditions that cause shortness of breath, such as heart failure and pulmonary hypertension. Overall, 62 (18.9%) patients could not be assigned a diagnosis. INTERPRETATION: In a group of community-based patients with shortness of breath being treated with inhalers, less than half ever had pulmonary function tests performed, and a considerable proportion had no evidence of lung disease or other conditions. These findings highlight the need for confirmatory testing, including pulmonary function tests, before prescribing inhalers for patients with presumed obstructive airway disorders.

BACKGROUND: Patients presenting to emergency departments (EDs) with acute atrial fibrillation or flutter undergo numerous transitions in care (TiC), including changes in their provider, level of care, and location. During transitions, gaps in communications and care may lead to poor outcomes. OBJECTIVE: We sought to examine the effectiveness of ED-based interventions to improve length of stay, return to normal sinus rhythm, and hospitalization, among other critical patient TiC outcomes. METHODS: Comprehensive searches of electronic databases and the gray literature were conducted. Two independent reviewers completed study selection, quality, and data extraction. Relative risks (RRs) with 95% confidence intervals (CIs) were calculated using a random-effects model, where appropriate. RESULTS: From 823 citations, 11 studies were included. Interventions consisted of within-ED clinical pathways (n = 6) and specialized observation units (n = 2) and post-ED structured patient education and referrals (n = 3). Three of five studies assessing hospital length of stay reported a significant decrease associated with TiC interventions. Patients undergoing within-ED interventions were also more likely to receive electrical cardioversion. Two of 3 clinical pathways reporting hospitalization proportions showed significant decreases associated with TiC interventions (RR = 0.63 [95% CI 0.42-0.92] and RR = 0.20 [95% CI 0.12-0.32]), as did 1 observation unit (RR = 0.54 [95% CI 0.36-0.80]). No significant differences in mortality, complications, or relapse were found between groupings among the studies. CONCLUSIONS: There is low to moderate quality evidence suggesting that within-ED TiC interventions may reduce hospital length of stay and decrease hospitalizations. Additional high-quality comparative effectiveness studies, however, are warranted.

BACKGROUND: Emergency department (ED) patients with uncomplicated atrial fibrillation (AF) of less than 48 hours may be safely managed with rhythm control. Although both chemical-first and electrical-first strategies have been advocated, there are no comparative effectiveness data to guide clinicians. METHODS: At six urban Canadian centers, ED patients ages 18 to 75 with uncomplicated symptomatic AF of less than 48 hours and CHADS2 score of 0 or 1 were randomized using concealed allocation in a 1:1 ratio to one of the following strategies: 1) chemical cardioversion with procainamide infusion, followed by electrical countershock if unsuccessful; or 2) electrical cardioversion, followed by procainamide infusion if unsuccessful. The primary outcome was the proportion of patients discharged within 4 hours of arrival. Secondary outcomes included ED length-of-stay (LOS); prespecified ED-based adverse events; and 30-day ED revisits, hospitalizations, strokes, deaths, and quality of life (QoL). RESULTS: Eighty-four patients were analyzed: 41 in the chemical-first group and 43 in the electrical-first group. Groups were balanced in terms of age, sex, vital signs, and CHADS2 scores. All patients were discharged home, with 83 (99%) in sinus rhythm. In the chemical-first group, 13 of 41 patients (32%) were discharged within 4 hours compared to 29 of 43 patients (67%) in the electrical-first group (p = 0.001). In the chemical-first group, the median ED LOS was 5.1 hours (interquartile range [IQR] = 3.5 to 5.9 hours) compared to 3.5 hours (IQR = 2.4 to 4.6 hours) in the electrical-first group, for a median difference of 1.2 hours (95% confidence interval = 0.4 to 2.0 hours, p < 0.001). No patients experienced stroke or death. All other outcomes, including adverse events, ED revisits, and QoL, were similar. CONCLUSION: In uncomplicated ED AF patients managed with rhythm control, chemical-first and electrical-first strategies both appear to be successful and well tolerated; however, an electrical-first strategy results in a significantly shorter ED LOS.

A 19-year-old female, university student with a long-standing history of migraine headaches presented to the emergency department (ED) with a 36-hour history of gradual onset of left-sided headache, preceded by visual aura. She stated that her headache was worse than usual and now associated with nausea, vomiting, and photophobia, despite use of oral ibuprofen. On examination, she was afebrile, her SaO2 = 98% on room air, her pulse was 110 beats/minute, and she was breathing 20 breaths/minute. She received a Canadian Triage and Acuity Scale score of 2 due to her pain score of 8/10 on a Visual Analogue Scale (VAS). Her neurological examination was normal and her neck was supple with full range of motion. She was a non-smoker, infrequent cannabis user, and her last menstrual period was normal.

OBJECTIVES: A variable proportion of patients presenting to the emergency department (ED) with acute asthma require admission to hospital. Previous studies have identified select factors associated with admission following ED presentation; however, no review has synthesized the evidence in this regard. This systematic review summarizes the evidence regarding factors associated with hospital admission following ED presentation. METHODS: Searches were conducted in seven electronic databases and common sources of grey literature. Studies reporting disposition for adults after ED presentation were included. Admission proportions and factors associated with hospitalization that remained statistically significant in multivariable analyses (p < 0.05) were reported. RESULTS: Out of an initial 5865 identified articles, 15 articles met full inclusion criteria and 11 were included in the analyses. Female sex (n = 2) and older age (n = 2) were individual factors associated with admission. Patient vital signs and severity followed by patient attributes were the two most frequent domains associated with admission. Admission proportions were analyzed in 10 studies at an median of â¼20% with no clear change between 1996 and 2012. CONCLUSIONS: Factors such as patient demographics (e.g., female sex, older age), patient vital signs/severity, and history are associated with admission following ED presentation for acute asthma. These can be employed by ED clinicians to effectively discern patients at high risk for admission and lead to more evidence-based decision-making.

Objective: Asthma is a common emergency department (ED) presentation. This study examined factors associated with inhaled corticosteroids/long-acting beta-agonist (ICS/LABA) use; and management and outcomes before and after ED presentation. Methods: Secondary analysis of a prospective cohort study; adults treated for acute asthma in Canadian EDs underwent a structured interview before discharge and were followed-up four weeks later. Patients received oral corticosteroids (OCS) at discharge and, at physician discretion, most received ICS or ICS/LABA inhaled agents. Analyses focused on ICS/LABA vs "other" treatment groups at ED presentation. Results: Of 807 enrolled patients, 33% reported receiving ICS/LABA at ED presentation; 62% were female, median age was 31 years. Factors independently associated with ICS/LABA treatment prior to ED presentation were: having an asthma action plan; using an asthma diary/peak flow meter; influenza immunization; not using the ED as usual site for prescriptions; ever using OCS and currently using ICS. Patients were treated similarly in the ED and at discharge; however, relapse was higher in the ICS/LABA group, even after adjustment. Conclusion: One-third of patients presenting to the ED with acute asthma were already receiving ICS/LABA agents; this treatment was independently associated with preventive measures. While ICS/LABA management improves control of chronic asthma, patients using these agents who develop acute asthma reflect higher severity and increased risk of future relapse.
