Purpose: Recent anecdotal reports suggest increasing numbers of people experiencing homelessness are visiting emergency departments (EDs) during cold weather seasons due to inadequate shelter availability. We examined monthly ED visits among patients experiencing homelessness to determine whether there has been a significant increase in such visits in 2022/2023 compared to prior years., Methods: We used linked health administrative data to identify cohorts experiencing homelessness in Ontario between October and March of the 2018/2019 to 2022/2023 years. We analyzed the monthly rate of non-urgent ED visits as a proxy measure of visits plausibly attributable to avoidance of cold exposure, examining rates among patients experiencing homelessness compared to housed patients. We excluded visits for overdose or COVID-19. We assessed level and significance of change in the 2022/2023 year as compared to previous cold weather seasons using Poisson regression., Results: We identified a total of 21,588 non-urgent ED visits across the observation period among patients experiencing homelessness in Ontario. Non-urgent ED visits increased 27% (RR 1.24 [95% CI 1.14-1.34]) in 2022/2023 compared to previous cold weather seasons. In Toronto, such visits increased by 70% (RR 1.68 [95% CI 1.57-1.80]). Among housed patients, non-urgent ED visits did not change significantly during this time period., Conclusion: Rates of ED visits plausibly attributable to avoidance of cold exposure by individuals experiencing homelessness increased significantly in Ontario in 2022/2023, most notably in Toronto. This increase in ED visits may be related to inadequate access to emergency shelter beds and warming services in the community., (© 2024.

Purpose: Homelessness increases the risk of cold-related injuries. We examined emergency department visits for cold-related injuries in Toronto over a 4-year period, comparing visits for patients identified as homeless to visits for patients not identified as homeless., Methods: This descriptive analysis of visits to emergency departments in Toronto between July 2018 and June 2022 used linked health administrative data. We measured emergency department visits with cold-related injury diagnoses among patients experiencing homelessness and those not identified as homeless. Rates were expressed as a number of visits for cold-related injury per 100,000 visits overall. Rate ratios were used to compare rates between homeless vs. not homeless groups., Results: We identified 333 visits for cold-related injuries among patients experiencing homelessness and 1126 visits among non-homeless patients. In each of the 4 years of observation, rate ratios ranged between 13.6 and 17.6 for cold-related injuries overall, 13.7 and 17.8 for hypothermia, and 10.3 and 18.3 for frostbite. Rates per 100,000 visits in the fourth year (July 2021 to June 2022) were significantly higher than in the pre-pandemic period. Male patients had higher rates, regardless of homelessness status; female patients experiencing homelessness had higher rate ratios than male patients experiencing homelessness., Conclusion: Patients experiencing homelessness visiting the emergency department are much more likely to be seen for cold-related injuries than non-homeless patients. Additional efforts are needed to prevent cold-related exposure and consequent injury among people experiencing homelessness., (© 2023.

Background: Security services in most settings are an essential part of emergency department (ED) care, but their role remains poorly understood. We sought to:(1) identify the frequency of security services involvement in ED care;(2) characterise the events security services are called for; and (3) identify temporal trends in use., Methods: We used a hospital-wide security database at a tertiary care ED in downtown Toronto, Ontario. Data from January 2017 to June 2021 related to the ED, patient or visitor related safety calls were included. We categorised calls by type of event (e.g.: Code White or Restraints). Call numbers were calculated as rates to adjust for visit volumes for each period. Univariate analyses were used to assess association between security services' calls and shift time, day of week, and month of the year., Results: Over the 4.5-year study period, 20,033 ED-related calls were recorded. On average, we identified 61 calls per 1000 patient visits. On univariate analysis, no increase in security calls were found based on day of week or month, but a disproportionate number of security calls were recorded overnight., Conclusion: This study reveals high security services involvement in the delivery of care in one urban ED. Security databases can inform improvement work and could be augmented by better coding of violent events and linkage with electronic health records when involving patients., (© 2022.

Objective: Individuals who experience assault are at high risk of being re-assaulted. Our objective was to identify reported incidences of re-assault and associated risk factors to better inform prevention strategies., Methods: We conducted a scoping review and searched databases (MEDLINE, PsychINFO, CINAHL, Cochrane Reviews, and Scopus) and grey literature. We performed abstract and full-text screening, and abstracted incidence of re-assault and information related to age, sex, socioeconomic status, mental illness, and incarceration., Results: We included 32 articles. Studies varied based on setting where index assaults were captured (n=18 inpatient only, n=13 emergency department or inpatient, n=1 other). Reported incidences ranged from 0.8% over one month to 62% through the lifetime. Important risk factors identified include young age, low socioeconomic status, racialized groups, history of mental illness or substance use disorder, and history of incarceration., Conclusions: Rates of re-assault are high and early intervention is necessary for prevention. We identified notable risk factors that require further in-depth analysis, including sex, gender and age-stratified analyses., Policy Implications: Key risk factors identified should inform timely and targeted intervention strategies for prevention., Competing Interests: Declaration of Competing Interest Dr. Gomez is a member of national and international medical associations that advocate for the reduction of violent injuries: the American College of Surgeons, the Trauma Association of Canada and the Panamerican Trauma Society.

Background: Individuals who experience a violence-related injury are at high risk for subsequent assault. The extent to which characteristics of initial assault are associated with the risk and intensity of reassaults is not well described yet essential for planning preventive interventions. We sought to describe the incidence of reassault and associated risk factors in Ontario, Canada., Methods: In this population-based retrospective cohort study using linked health and demographic administrative databases, we included all individuals discharged from an emergency department or hospitalised with a physical assault between 1 April 2005 and 30 November 2016 and followed them until 31 December 2016 for reassault. A sex-stratified Andersen-Gill recurrent events analysis modelled associations between sociodemographic and clinical risk factors and reassault., Results: 271 522 individuals experienced assault (mean follow-up=6.4 years), 24 568 (9.0%) of whom were reassaulted within 1 year, 45 834 (16.9%) within 5 years and 52 623 (19.4%) within 10 years. 40 322 (21%) males and 12 662 (17%) females experienced reassault over the study period. Groups with increased rates of reassault included: those aged 13-17 years versus older adults (age 65+) (males: relative rate (RR) 2.16; 95% CI 1.96 to 2.38; females: RR 2.79; 95% CI 2.39 to 3.26)), those living in rural areas versus urban (males: RR 1.22; 95% CI 1.19 to 1.24; females: RR 1.32; 95% CI 1.27 to 1.37) and individuals with a history of incarceration versus without (males: RR 2.38; 95% CI 2.33 to 2.42; females: RR 2.57; 95% CI 2.48 to 2.67)., Conclusion: One in five who are assaulted experience reassault. Those at greatest risk include youth, those living in rural areas, and those who have been incarcerated, with strongest associations among females. Timely interventions to reduce the risk of experiencing reassault must consider both sexes in these groups., Competing Interests: Competing interests: DG is a member of national and international medical associations that advocate for the reduction of violent injuries: the American College of Surgeons, the Trauma Association of Canada and the Panamerican Trauma Society.

As of January 2019, over half of all doctors working in Canada under the age of 40 were women. Despite equal representation in the profession of medicine, women still experience harassment, discrimination, and pay inequity when compared to their male colleagues. Gender discrimination is present at all levels of medical training and negatively impacts women who want to become emergency physicians. The right to gender equity is part of the Canadian Charter of Rights and Freedoms. The World Health Organization states that "gender inequities are socially generated and, therefore, can be changed." CAEP recognizes that gender equity is important to its members and that it intersects with inequities experienced by other minority groups. This position statement from the committee for Women in Emergency Medicine (EM) is intended to support women and those who identify as women who have chosen EM as their career. Furthermore, it is meant to inform and support policy makers as they consider the unique challenges that women face in their pursuit of excellence in EM.

Background: It is unclear what the best strategy is for detecting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among residents of homeless shelters and what individual factors are associated with testing positive for the virus. We sought to evaluate factors associated with testing positive for SARS-CoV-2 among residents of homeless shelters and to evaluate positivity rates in shelters where testing was conducted in response to coronavirus disease 2019 (COVID-19) outbreaks or for surveillance., Methods: We conducted a retrospective chart audit to obtain repeated cross-sectional data from outreach testing done at homeless shelters between Apr. 1 and July 31, 2020, in Toronto, Ontario, Canada. We compared the SARS-CoV-2 positivity rate for shelters where testing was conducted because of an outbreak (at least 1 known case) with those tested for surveillance (no known cases). A patient-level analysis evaluated differences in demographic, health and behavioural characteristics of residents who did and did not test positive for SARS-CoV-2 at shelters with at least 2 positive cases., Results: One thousand nasopharyngeal swabs were done on 872 unique residents at 20 shelter locations. Among the 504 tests done in outbreak settings, 69 (14%) were positive for SARS-CoV-2 and 1 (0.2%) was indeterminate. Among the 496 tests done for surveillance, 11 (2%) were positive and none were indeterminate. Shelter residents who tested positive for SARS-CoV-2 were significantly less likely to have a health insurance card (54% v. 72%, p = 0.03) or to have visited another shelter in the last 14 days (0% v. 18%, p < 0.01). There was no association between SARS-CoV-2 positivity and medical history or symptoms., Interpretation: Our findings support testing of asymptomatic shelter residents for SARS-CoV-2 when a positive case is identified at the same shelter. Surveillance testing when there are no known positive cases may detect outbreaks, but further research should identify efficient strategies given scarce testing resources., Competing Interests: Competing interests: Tara Kiran is the Fidani Chair in Improvement and Innovation at the University of Toronto.

The goal of this study was to determine the injury profiles of Canadian children who presented to the Emergency Department from 1990 to 2016 due to an injury caused while traveling in a form of land transportation that did not require child restraint. A case series was conducted using data from the electronic Canadian Hospitals Injury Reporting and Prevention Program (eCHIRPP). Children who were injured while travelling on land transportation for which child restraint is not required, who presented to a Canadian Emergency Department that participates in eCHIRPP between April 1, 1990 to August 29, 2016, were included. Overall, 1856 children sustained 2139 injuries (mean age: 9.8 years (SD 4.5), 45.5% male). The majority of children were injured on a school bus (49.3%). The most commonly injured body part was the head or neck (52.6%). The most common type of injury was a superficial or open wound (33.1%), followed by traumatic brain injury (19.3%). Overall, 39.4% of injuries required no treatment in hospital. Overall, approximately 70 children presented to eCHIRPP EDs per year on a land transportation vehicle that does not require restraints. Biomechanical studies are needed to improve safety on land transportation vehicles that do not require seatbelts.

Background: We aimed to determine the costs of emergency department (ED) attendance by persons with inflammatory bowel disease (IBD) not admitted to hospital from the ED., Methods: This was a population-based administrative database study linking the University of Manitoba IBD Epidemiology Database with the Winnipeg Regional Health Authority (WRHA) ED Information Service database. We identified persons with IBD who presented to the ED and were not admitted between January 1, 2009 and March 31, 2012. We then applied costs in Canadian dollars for these visits including an average ED visit cost plus 26% for overhead (total = $508), an average estimated cost of laboratory investigations ($50), and costs for each of radiographic imaging, lower endoscopy and consultation with an internist/gastroenterologist or a surgeon. We tallied the costs of each unique ED presentation. We determined average costs for visits associated with specific consultations or investigations., Results: One thousand six hundred and eighty-two persons with IBD (4,853 individual visits) attended the ED and did not get hospitalized. The average cost per ED visit by a person with IBD who did not get hospitalized was $650. This resulted in a total expenditure of $3,152,227 on these persons for their ED attendance or $969,916 per year. The visits with the highest mean costs were those associated with an abdominal computerized tomography scan ($979), those associated with surgical consultation ($1019), and those associated with an internist/gastroenterologist consultation ($942)., Conclusion: Better strategies for management of acute issues for persons with IBD that can reduce the use of an ED are needed and can be considerably cost saving., (© The Author(s) 2019.

In June of 2016, the Collaborative Working Group (CWG) on the Future of Emergency Medicine presented its final report at the Canadian Association of Emergency Physicians (CAEP) annual meeting in Quebec City. The CWG report made a number of recommendations concerning physician Human Health Resource (HHR) shortfalls in emergency medicine, specific changes for both the Royal College of Physicians and Surgeons of Canada (FRCPC) and the College of Family Physicians of Canada (CCFP-EM) training programs, HHR needs in rural and remote hospitals, future collaboration of the CCFP-EM and FRCPC programs, and directions for future research. All recommendations were endorsed by CAEP, the Royal College of Physicians and Surgeons of Canada (RCPSC), and the College of Family Physicians of Canada (CFPC). The CWG report was published in CJEM and has served as a basis for ongoing discussion in the emergency medicine community in Canada. The CWG identified an estimated shortfall of 478 emergency physicians in Canada in 2016, rising to 1071 by 2020 and 1518 by 2025 assuming no expansion of EM residency training capacity. In 2017, the CAEP board struck a new committee, The Future of Emergency Medicine in Canada (FEMC), to advocate with appropriate stakeholders to implement the CWG recommendations and to continue with this important work. FEMC led a workshop at CAEP 2018 in Calgary to develop a regional approach to HHR advocacy, recognizing different realities in each province and region. There was wide representation at this workshop and a rich and passionate discussion among those present. This paper represents the output of the workshop and will guide subsequent deliberations by FEMC. FEMC has set the following three goals as we work toward the overarching purpose to improve timely access to high quality emergency care: (1) to define and describe categories of emergency departments (EDs) in Canada, (2) define the full time equivalents required by category of ED in Canada, and (3) recommend the ideal combination of training and certification for emergency physicians in Canada. A fourth goal supports the other three goals: (4) urge further consideration and implementation of the CWG-EM recommendations related to coordination and optimization of the current two training programs. We believe that goals 1 and 2 can largely be accomplished by the CAEP annual meeting in 2020, and goal 3 by the CAEP annual meeting in 2021. Goal 4 is ongoing with both the RCPSC and the CFPC. We urge the EM community across Canada to engage with our committee to support improved access and EM care for all Canadians.

Canadian specialist emergency medicine (EM) residency training is undergoing the most significant transformation in its history. This article describes the rationale, process, and redesign of EM competency-based medical education. The rationale for this evolution in residency education includes 1) improved public trust by increasing transparency of the quality and rigour of residency education, 2) improved fiscal accountability to government and institutions regarding specialist EM training, 3) improved assessment systems to replace poor functioning end-of-rotation assessment reports and overemphasis on high-stakes, end-of-training examinations, and 4) and tailored learning for residents to address individualized needs. A working group with geographic and stakeholder representation convened over a 2-year period. A consensus process for decision-making was used. Four key design features of the new residency education design include 1) specialty EM-specific outcomes to be achieved in residency; 2) designation of four progressive stages of training, linked to required learning experiences and entrustable professional activities to be achieved at each stage; 3) tailored learning that provides residency programs and learner flexibility to adapt to local resources and learner needs; and 4) programmatic assessment that emphasizes systematic, longitudinal assessments from multiple sources, and sampling sentinel abilities. Required future study includes a program evaluation of this complex education intervention to ensure that intended outcomes are achieved and unintended outcomes are identified.

Purpose: Pharmacy claims data is often used in pharmacoepidemiology studies, but no studies to date have examined whether it was possible to identify the use of blister packs in these databases. We aimed to determine whether medications dispensed in days divisible by 7 are more likely to be blister packed than medications dispensed in other quantities., Methods: Community pharmacies in Manitoba were invited to participate in a mail-out survey to identify the use of blister packaging for up to 25 patients who had a solid oral medication dispensed from April 1, 2012 to March 31, 2014. Eligible medications were identified using the population-based province-wide retail pharmacy network. Algorithms for identifying the use of blister packaging were determined by comparing the proportion of fills that confirmed blister pack use between different days supply quantities., Results: Twenty-seven out of 32 pharmacies that agreed to participate completed the survey. The total number of prescriptions in the analysis was 2045 of which 131 (6.4%) were dispensed in blister packaging. Overall, prescriptions dispensed in days divisible by 7 yielded a 72.5% sensitivity, 86.6% specificity, 30.3% PPV, and 97.9% NPV compared with prescriptions dispensed in other quantities. A 28-day to 30-day comparison yielded an 87.9% sensitivity, 96.1% specificity, 64.6% PPV, and 99.0% NPV., Conclusion: While the NPV was high, the PPV for identifying blister packaging using the days supply field in pharmacy claims data was modest given the low prevalence in blister pack use. The best predictor occurred when 28 days was compared with 30 days. KEY POINTS Blister packs are arranged in 4 × 7 compartments and are often used to improve adherence, but no studies have examined whether it was possible to identify the use of blister packs using the days supply field in pharmacy claims data. Findings show that a 28-day supply yielded a high sensitivity and specificity for identifying the use of blister packaging compared with a 30-day supply, but there is potential for misclassification. Future studies directed at examining subgroups that are more likely to use blister packs and replication of findings using other data sources in other jurisdictions are encouraged., (Copyright © 2017 John Wiley & Sons, Ltd.)

Aims: The aim of this study was to assess the predictive validity of the DA-5 with the addition of a strangulation item in evaluating the risk of an intimate partner violence (IPV) victim being nearly killed by an intimate partner., Background: The DA-5 was developed as a short form of the Danger Assessment for use in healthcare settings, including emergency and urgent care settings. Analyzing data from a sample of IPV survivors who had called the police for domestic violence, the DA-5 was tested with and without an item on strangulation, a potentially fatal and medically damaging IPV tactic used commonly by dangerous abusers., Design: Researchers interviewed a heterogeneous sample of 1,081 women recruited by police between 2009-2013 at the scene of a domestic violence call; 619 (57.3%) were contacted and re-interviewed after an average of 7 months., Methods: The predictive validity of the DA-5 was assessed for the outcome of severe or near lethal IPV re-assault using sensitivity, specificity and ROC curve analysis techniques., Results: The original DA-5 was found to be accurate (AUC = .68), equally accurate with the strangulation item from the original DA substituted (AUC = .68) and slightly more accurate (but not a statistically significant difference) if multiple strangulation is assessed., Conclusion: We recommend that the DA-5 with the strangulation item be used for a quick assessment of homicide or near homicide risk among IPV survivors. A protocol for immediate referral and examination for further injury from strangulation should be adopted for IPV survivors at high risk., (© 2017 John Wiley & Sons Ltd.)

Tetanus is a life-threatening clinical syndrome that commonly presents with muscular spasms, rigidity, and autonomic instability. It is considered rare in industrialized countries, and tetanus occurring secondary to dental abscesses, procedures, or infections has been infrequently reported. We describe the case of a patient inadequately immunized for tetanus, who presented to the emergency department with muscular spasms, rigidity, and autonomic instability in the setting of an odontogenic infection. A clinical diagnosis of tetanus was made and subsequently managed successfully.

Background: Scientists have called for strategies to identify ED patients with unmet needs. We identify the unique profile of ED patients who arrive by ambulance and subsequently leave without consulting a provider (ie, a paradoxical visit, PV)., Methods: Using a retrospective cohort design, administrative data from Winnipeg, Manitoba were interrogated to identify all ED patients 17+ years old as having zero, single or multiple PVs in 2012/2013. Analyses compare the sociodemographic, physical (eg, arthritis), mental (eg, substance abuse) and concurrent healthcare use profile of non-PV, single and multiple PV patients., Results: The study cohort consisted of 122 639 patients with 250 754 ED visits. Across all ED sites, 2.3% of patients (N=2815) made 3387 PVs, comprising 1.4% of all ED visits. Descriptively, more single versus non-PV patients lived in urban core and lowest-income areas, were frequent ED users generally, were substance abusers and had seven plus primary care physician visits. Multiple PV patients had a similar but more extreme profile versus their single PV counterparts (eg, 54.7% of multiple vs 27.4% of single PV patients had substance abuse challenges). From multivariate statistics, single versus non-PV patients are defined uniquely by their frequent ED use, by their substance abuse, as living in a core and low income area, and as having multiple visits with primary care physicians., Conclusions: PV patients have needs that do not align with the acute model of ED care. These patients may benefit from a more integrated care approach likely involving allied health professionals., (Published by the BMJ Publishing Group Limited.

Background: To describe the patterns and predictors of emergency department (ED) attendance and post-ED hospitalization by persons with inflammatory bowel disease (IBD)., Methods: We linked the University of Manitoba IBD Epidemiology Database with the Emergency Department Information System of the Winnipeg Regional Health Authority to determine the rates of presentation to the ED by persons with IBD from January 01, 2009 to March 31, 2012. Incident cases were diagnosed during the study period and all others were considered prevalent cases. Multivariate logistic regression was used to determine predictors of attendance in the ED and for hospitalization within 2 days of ED attendance., Results: The study population included 300 incident and 3394 prevalent IBD cases, of whom 76% and 49%, respectively, attended the ED at least once during the study period. Incident cases with Crohn's disease or with a history of opioid use were more likely to attend the ED. Those who had seen a gastroenterologist within the year before diagnosis were less likely to visit the ED. Among prevalent cases, higher comorbidity, opioid or corticosteroid use, and recent hospital admission were predictive of ED attendance and those who saw only 1 physician in the preceding year had lower ED attendance. Presenting to the ED with a primary gastrointestinal complaint was the strongest predictor of subsequent hospital admission., Conclusions: ED attendance by both incident and prevalent cases of IBD is high. Identified predictors of ED attendance and post-ED hospitalization could guide the optimization of outpatient IBD care to limit ED attendance and potentially post-ED hospitalization.

Objectives: To estimate and compare Canadian homicide mortality rates (HMRs) and trends in HMRs across age groups, with a focus on trends for youth., Methods: Data for the period of 2000 to 2009 were collected from Statistics Canada's CANSIM (Canadian Statistical Information Management) Table 102-0540 with the following ICD-10-CA coded external causes of death: X85 to Y09 (assault) and Y87.1 (sequelae of assault). Annual population counts from 2000 to 2009 were obtained from Statistics Canada's CANSIM Table 051-0001. Both death and population counts were organized into five-year age groups. A random effects negative binomial regression analysis was conducted to estimate age group-specific rates, rate ratios, and trends in homicide mortality., Results: There were 9,878 homicide deaths in Canada during the study period. The increase in the overall homicide mortality rate (HMR) of 0.3% per year was not statistically significant (95% CI: -1.1% to +1.8%). Canadians aged 15-19 years and 20-24 years had the highest HMRs during the study period, and experienced statistically significant annual increases in their HMRs of 3% and 4% respectively (p &lt; 0.05). A general, though not statistically significant, decrease in the HMR was observed for all age groups 50+ years. A fixed effects negative binomial regression model showed that the HMR for males was higher than for females over the study period [RRfemale/male = 0.473 (95% CI: 0.361, 0.621)], but no significant difference in sex-specific trends in the HMR was found., Conclusion: An increasing risk of homicide mortality was identified among Canadian youth, ages 15-24, over the 10-year study period. Research that seeks to understand the reasons for the increased homicide risk facing Canada's youth, and public policy responses to reduce this risk, are warranted.

Background: Violent interpersonal injury is a common presentation to emergency departments (EDs) and is increasingly being treated as a preventable condition. Given the complexity of the issue, it is key to ensure interventions are feasible and acceptable within the communities that are affected by violence. Our team consists of ED staff, community members who work with youth affected by violence, people who were affected by violence in their youth, and researchers., Objectives: We describe how an integrated knowledge translation (KT) process was used to develop an ED violence intervention program (EDVIP) for youth affected by violence., Methods: We used the Canadian Institutes of Health Research Guidelines for integrated KT (iKT) to develop an EDVIP. Specifically, we report the Knowledge to Action process which involves both knowledge creation and an action cycle., Results: Our team determined the research question, the research approach, assessed feasibility and determined outcomes for our study. Using the iKT approach facilitated initiation of a funded trial that is now active., Conclusions: This paper highlights the benefit of including community experts at the beginning of and throughout the research process.

Introduction: Injury by violence is the fourth cause of death and the leading reason for a youth to visit an emergency department (ED) in Canada. In Winnipeg, 20% of youth who visit an ED with an injury due to violence have a second visit for a subsequent violent injury within 1 year. Youth injured by violence are in a reflective and receptive state of mind, rendering the ED setting appropriate for intervention., Methods and Analysis: This protocol describes a wraparound care model delivered by a support worker with lived experience with violence, supported by social workers and links to multiple community partners. Support workers will be on call 24 h a day, 7 days a week in order to start the intervention in the ED and take advantage of the 'teachable moment'. The protocol is of a pilot randomised control trial to assess the feasibility of a randomised control trial designed to assess efficacy. For the pilot trial, we will assess recruitment, treatment fidelity, participant adherence and safety. The intervention arm will receive wraparound care initiated at the time of their visit for injury due to violence. The control arm will receive standard care. We will use an adapted preconsent randomisation methodology. This intervention has been developed using an integrated knowledge translation approach., Discussion: Interventions delivered in the ED for youth injured by violence require an approach that is appropriate for the unique situation the youth are in., Ethics: The University of Manitoba Health Research Ethics Board (HS 16445 (Cohort study) and HS 16444 (WrapAround Care study) granted ethical approval., Trial Registration Number: NCT01895738., (Published by the BMJ Publishing Group Limited.

Objective: To determine the perceptions and roles of referees about violence and injury in hockey games., Design: Questionnaire., Setting: Web-based survey., Participants: We contacted referees across Canada from various leagues and all levels of play, with the majority of respondents from Ontario (92%)., Main Outcome Measures: We gathered demographic information anonymously and posed questions on aggression and experience in hockey games., Results: The majority of referees (n = 632) indicated that violence is a serious concern to both players and referees at all levels of hockey. More than 90% of referees responded that they were the recipients of aggression and anger (92.1%, 95% confidence interval, 90.0-94.2), 55% had been involved in hockey games where aggressive behavior resulted in the referee losing control of the game, and 71% said that this increased aggression leads to injury. Referees' opinions are that the coach is the most responsible for managing on-ice safety (63%). To improve hockey safety, referees suggest education and more rigorous enforcement of discipline for all participants., Conclusions: Referees are important for hockey safety and need to be appropriately supported. Referees believe that increased aggression can lead to injury and that rules need to be enforced more diligently. Referees recommend that increased education about safety is needed to guide parents, coaches, and players to make hockey safer.

Facebook and social media networking applications use is ubiquitous across all ages and cultures. Facebook has finally begun to appear in the medical-scientific press. Today's medical literature is focused on concerns of professionalism in young health care practitioners vis-à-vis the lay public as they continuously expose themselves through this online social medium. With over 500 million users, Facebook hosts many of our patients, who are also exposed to the Internet and social media. Nobody so far has considered the opposite issue: that of physician invasion of privacy by "looking-up" a patient on Facebook during clinical practice for purposes of history-taking or diagnostic clues in situations where patients are too ill to provide needed information. We need to consider the ethical implications of privacy invasion in the current era of information technology. We need to acquire and maintain a certain level of "social media competency" to better debate the issues around Facebook and how we integrate on-line content with our patients' histories of present illness (HPI) or past medical histories (if at all)., (© 2011 by the Society for Academic Emergency Medicine.)

Objectives: Women assaulted by intimate partners are frequently patients in emergency departments (EDs). Many victims and health care providers fail to take into account the potential risks of repeat partner violence. The objective of this study was to use data from a larger study of domestic violence risk assessment methods to develop a brief assessment for acute care settings to identify victims at highest risk for suffering severe injury or potentially lethal assault by an intimate partner or former partner., Methods: Victims of intimate partner violence (IPV) were interviewed twice between 2002 and 2004. The baseline interview included the 20 items of Campbell's Danger Assessment (DA; predictor). The follow-up interview, conducted 9 months later on average, assessed abuse inflicted since the baseline interview (outcome). Multiple logistic regression was used to identify questions on the DA most predictive of severe abuse and potentially lethal assaults. Female IPV victims were recruited from New York City family courts, Los Angeles County Sheriff's Department 9-1-1 calls, New York City and Los Angeles shelters, and New York City hospitals; 666 women responded to the DA at baseline, and 60% participated in follow-up interviews., Results: Severe injuries or potentially lethal assaults were experienced by 14.9% of retained study participants between the baseline and follow-up interviews. The best brief prediction instrument has five questions. A positive answer to any three questions has a sensitivity of 83% (95% confidence interval = 70.6% to 91.4%)., Conclusions: This instrument can help predict which victims may be at increased risk for severe injury or potentially lethal assault and can aid clinicians in differentiating which patients require comprehensive safety interventions., ((c) 2009 by the Society for Academic Emergency Medicine.)

Objective: Youth violence continues to trouble Canadians. Emergency department (ED) visits by youth after a violent injury may represent a "teachable moment," and thus secondary violence prevention interventions may be effective. We conducted a systematic review to identify the success rates of any interventions, the populations likely to benefit and the outcome measures used., Data Source: We searched 8 databases (i.e., MEDLINE, EMBASE, PubMed, CINAHL, the Cochrane Database of Systematic Reviews, the ACP Journal Club, DARE and CENTRAL)., Study Selection: Studies were included if they described and evaluated an intervention, were health care-based and targeted youth who were injured by violence. Two blinded investigators selected 15 articles from 181 abstracts. After full-text review, 8 articles were excluded, leaving 7 articles from 4 intervention programs., Data Extraction: All interventions used ED case management of the violently injured patient. One randomized control trial (RCT) demonstrated a significant reduction in reinjury rates (treatment group 8.1% v. control group 20.3%, p = 0.05). Another small RCT found no statistically significant reductions in repeat violence or service use. One retrospective cohort study demonstrated a lower relative risk (RR) in future criminal justice involvement (RR = 0.67, 95% confidence interval 0.45-0.99). A retrospective study of pediatric patients with violent injuries found only 1% of these youth returned with injuries as a result of repeat violence., Data Synthesis: Although all 4 case management interventions that we reviewed showed promise in the United States, small sample sizes and incomplete follow-up limited their ability to demonstrate significant decreases in reinjury., Conclusion: Future research is necessary to help EDs capitalize on the opportunity to effectively reduce youth violence.
