Intimate partner violence and human trafficking commonly affect patients presenting to the emergency department including the trauma bay. Although these forms of violence and exploitation are not always the underlying cause of that particular emergency department encounter, screening is important regardless of the presenting condition because this presentation may be the only opportunity to receive help and ultimately plants the seed for future access to help regardless of what a patient chooses to do following this first encounter. There are important medical care considerations in these patients beyond trauma bay procedures that can make the difference in saving a life.

Obstetrical patients are at risk of complications from COVID-19 and face increased stress due to the pandemic and changes in hospital birth setting. The objective was to describe the perinatal care experiences of obstetrical patients who gave birth during the early phases of the COVID-19 pandemic.A descriptive epidemiological survey was administered to consenting patients who gave birth at The Ottawa Hospital (TOH) between March 16th and June 16th, 2020. The participants reported on prenatal, in-hospital, and postpartum care experiences. COVID-19 pandemic related household stress factors were investigated. Frequencies and percentages are presented for categorical variables and median and interquartile range (IQR) for continuous variables.A total of 216 participants were included in the analyses. Median participants age was 33 years (IQR: 30-36). Collectively, 94 (43.5%) participants felt elevated stress for prenatal appointments and 105 (48.6%) for postpartum appointments because of COVID-19. There were 108 (50.0%) were scared to go to the hospital for delivery, 97 (44.9%) wore a mask during labour and 54 (25.0%) gave birth without a support person. During postpartum care, 125 (57.9%) had phone appointments (not offered prior to COVID-19), and 18 (8.3%) received no postpartum care at all.COVID-19 pandemic and public health protocols created a stressful healthcare environment for the obstetrical population where many were fearful of accessing services, experienced changes to standard care, or no care at all. As the pandemic continues, careful attention should be given to the perinatal population to reduce stress and improve continuity of care.RéSUMé: OBJECTIF: Les patients obstétriques sont à risque de complications de la COVID-19 et font face à un stress accru en raison de la pandémie et des changements dans le cadre de l’accouchement en milieu hospitalier. L’objectif était de décrire les expériences de soins périnataux des patients obstétriques qui ont accouché au cours des premières phases de la pandémie de COVID-19. MéTHODES: Un sondage épidémiologique descriptif a été menée auprès de patients qui ont accouché à L'Hôpital d'Ottawa (TOH) entre le 16 mars et le 16 juin 2020. Les participants ont fait un compte rendu de leurs expériences en matière de soins prénataux, hospitaliers et post-partum. Les facteurs de stress domestique liés à la COVID-19 ont été étudiés. Les fréquences et les pourcentages sont présentés pour les variables catégorielles et la médiane et l'écart interquartile (IQR) sont présentés pour les variables continues. RéSULTATS: Au total, 261 participants ont répondu au sondage. L'âge maternel médian était de 33 ans (IQR: 30–36). Collectivement, 94 participants (43,5%) ressentaient un stress élevé en lien avec les rendez-vous prénataux et 105 (48,6%) pour les rendez-vous post-partum en raison de la COVID-19. Il y avait 108 patients (50,0%) qui avaient peur d'aller à l'hôpital pour accoucher, 97 (44,9%) qui portaient un masque pendant leur travail et 54 (25,0%) qui ont accouché sans personne de soutien. En lien avec les soins post-partum, 125 (57,9%) ont eu des rendez-vous téléphoniques (non offerts avant la pandémie COVID-19) et 18 (8,3%) n'ont reçu aucun soin post-partum. CONCLUSION: La pandémie de COVID-19 et les politiques de santé publique ont créé un environnement de soins de santé stressant pour la population obstétrique où beaucoup avaient peur d'accéder aux services de soins, ont connu des changements dans les soins de base ou n’ont pas eu de soins du tout. Alors que la pandémie se poursuit, une attention particulière doit être accordée à la population périnatale afin de réduire le stress et améliorer la continuité des soins.

Objective Nonoccupational postexposure prophylaxis (nPEP) programs offer antiretroviral therapy to prevent HIV following at-risk exposures like sexual assault. We investigated the levels of elective nPEP uptake among sexual assault cases presenting for emergency medical care. Design Retrospective analysis. Methods The analysis included over 3 years (1 January 2015 to 30 September 2018) of clinic information from the Sexual Assault and Partner Abuse Care Program (SAPACP) at The Ottawa Hospital, the regional emergency department care point following sexual assault. Descriptive analyses assessed the number of cases eligible for nPEP and those who started nPEP. Bivariable/multivariable logistic regression modelling assessed factors most strongly associated with starting nPEP using odds ratios (OR), adjusted OR (AOR), and 95% confidence intervals (CI). Results The SAPACP saw 1712 patients; 1032 were sexual assault cases, 494 were eligible for nPEP, and 307/494 (62%) eligible patients started nPEP. The median age was 23 years (IQR: 20-31), with 446 (90%) cases being female. There were 86 (17%) cases who arrived by ambulance, and 279 (56%) assaults involving a known assailant. Reduced odds of starting nPEP were observed among female cases (AOR: 0.44, 95% CI: 0.21-0.93), those who arrived by ambulance (AOR: 0.56, 95% CI: 0.35-0.91), and those with a known assailant (AOR: 0.56, 95% CI: 0.36-0.78). Conclusion We found that 62% of eligible sexual assault cases started nPEP. Key groups most likely to decline nPEP included female cases, those who arrived by ambulance, and those with known assailants. Providers can use these findings to provide recommendations to sexual assault survivors most likely to decline nPEP, yet still in need of care.

ImportanceLockdown measures and the stress of the COVID-19 pandemic are factors associated with increased risk of violence, yet there is limited information on trends in emergency department (ED) encounters for sexual assault.ObjectiveTo compare changes in ED encounters for sexual assault during the COVID-19 pandemic vs prepandemic estimates.Design, Setting, and ParticipantsThis retrospective, population-based cohort study used linked health administrative data from 197 EDs across Ontario, Canada, representing more than 15 million residents. Participants included all patients who presented to an ED in Ontario from January 11, 2019, to September 10, 2021. Male and female individuals of all ages were included. Data analysis was performed from March to October 2022.ExposuresSexual assault, defined through 27 International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, procedure and diagnoses codes.Main Outcomes and MeasuresTen bimonthly time periods were used to compare differences in the frequency and rates of ED encounters for sexual assault between 2020 to 2021 (during the pandemic) compared with baseline prepandemic rates in 2019. Rate differences (RDs) and age adjusted rate ratios (aRRs) and Wald 95% CIs were calculated using Poisson regression.ResultsFrom January 11, 2019, to September 10, 2021, there were 14 476 656 ED encounters, including 10 523 for sexual assault (9304 [88.4%] among female individuals). The median (IQR) age was 23 (17-33) years for female individuals and 15 (4-29) years for male individuals. Two months before the pandemic, ED encounters increased for sexual assault among female individuals (8.4 vs 6.9 cases per 100 000; RD, 1.51 [95% CI, 1.06 to 1.96]; aRR, 1.22 [95% CI, 1.09 to 1.38]) and male individuals (1.2 vs 1.0 cases per 100 000; RD, 0.19 [95% CI, 0.05 to 0.36]; aRR, 1.19 [95% CI, 0.87 to 1.64]). During the first 2 months of the pandemic, the rates decreased for female individuals (4.2 vs 8.3 cases per 100 000; RD, −4.07 [95% CI, −4.48 to −3.67]; aRR, 0.51 [95% CI, 0.44 to 0.58]) and male individuals (0.5 vs 1.2 cases per 100 000; RD, −0.72 [95% CI, −0.86 to −0.57]; aRR, 0.39 [95% CI, 0.26 to 0.58]). For the remainder of the study period, the rates of sexual assault oscillated, returning to prepandemic levels during the summer months and between COVID-19 waves.Conclusions and RelevanceThese findings suggest that lockdown protocols should evaluate the impact of limited care for sexual assault. Survivors should still present to EDs, especially when clinical care or legal interventions are needed.

BackgroundThere is little information on care-seeking patterns for sexual assault and domestic violence during the COVID-19 pandemic. The objective of this study was to examine the changes in emergency department (ED) admissions for sexual assault and domestic violence since the COVID-19 pandemic was declared.MethodsObservational ED admissions data from The Ottawa Hospital were analyzed from March 4 to May 5 (62 days) in 2020 (COVID-19 period) and compared to the same period in 2018 (pre-COVID-19). Total and mean weekly admissions were calculated for all-cause ED admissions and for sexual and domestic violence cases. A Poisson regression (without offset term) was used to calculate the weekly case count ratio and 95% confidence intervals (CI) between the two time periods. Case characteristics were compared using chi-square tests, and percent differences were calculated.ResultsCompared to pre-COVID-19, total ED admissions dropped by 1111.22 cases per week (32.9% reduction), and the Sexual Assault and Domestic Violence Program cases dropped 4.66 cases per week. The weekly case count ratio for sexual assault cases was 0.47 (95% CI 0.79–0.27), equivalent of 53.49% reduction in cases, and 0.52 (95% CI 0.93–0.29), equivalent to a 48.45% reduction in physical assault cases. The characteristics of presenting cases were similar by age (median 25 years), sex (88.57% female), assault type (57.14% sexual assault, 48.57% physical assault), and location (31.43% patient’s home, 40.00% assailant’s home). There was a significant increase in psychological abuse (11.69% vs 28.57%) and assaults occurring outdoors (5.19% vs 22.86%).ConclusionThis study found a decrease in ED admissions for sexual assault and domestic violence during COVID-19, despite societal conditions that elevate risk of violence. Trends in care-seeking and assault patterns will require ongoing monitoring to inform the provision of optimal support for individuals experiencing violence, particularly as countries begin to re-open or lock-down again.

The emergency department (ED) is an at-risk area for medical error. We determined the characteristics of patients with unanticipated and anticipated death within 7 days of ED discharge and whether medical error contributed.We performed a single-centre health records review of 200 consecutive cases during a 3-year period from 2014 to 2017 in two urban, academic, tertiary care EDs. We included patients evaluated by an emergency physician who were discharged and died within 7 days. Three trained and blinded reviewers determined if deaths were related to the index visit, anticipated or unanticipated, and/or due to potential medical error. Reviewers performed content analysis to identify themes.Of 200 cases, 129 had sufficient information for analysis, translating to 44 deaths per 100,000 ED discharges (200/458,634). 13 cases per 100,000 ED discharges (58/458,634) were related and unanticipated deaths. 4 cases per 100,000 were due to potential medical errors (18/458,634). Over half (52.7%) of 129 patients displayed abnormal vital signs at discharge. Pneumonia (27.1%) was the most common cause of death. Patient themes were: difficult historian, multiple complaints, multiple comorbidities, acute progression of chronic disease, and recurrent falls. Provider themes were: failure to consider infectious etiology, failure to admit high-risk elderly patient, and missed diagnosis. System themes were: multiple ED visits or recent admission, and no repeat vital signs recorded.Though the frequency of related and unanticipated deaths and those due to medical error was low, clinicians should carefully consider the highlighted common patient, provider, and system themes to facilitate safe discharge from the ED.RéSUMé: CONTEXTE: Le service des urgences (SU) est un secteur à risque pour les erreurs médicales. Nous avons déterminé les caractéristiques des patients dont le décès a été anticipé ou non dans les 7 jours suivant la sortie des urgences et si une erreur médicale y a contribué. MéTHODES: Nous avons réalisé une étude monocentrique des dossiers médicaux de 200 cas consécutifs sur une période de trois ans, de 2014 à 2017, dans deux urgences urbaines, universitaires et de soins tertiaires. Nous avons inclus les patients évalués par un médecin urgentiste qui sont sortis de l'hôpital et sont décédés dans les 7 jours. Trois examinateurs formés et en aveugle ont déterminé si les décès étaient liés à la visite de référence, anticipés ou non, et/ou dus à une erreur médicale potentielle. Les examinateurs ont effectué une analyse de contenu pour identifier les thèmes. RéSULTATS: Sur 200 cas, 129 disposaient d'informations suffisantes pour l'analyse, ce qui correspond à 44 décès pour 100 000 sorties des urgences (200/458 634). 13 cas pour 100 000 sorties des urgences (58/458 634) étaient des décès liés et imprévus. 4 cas pour 100 000 étaient dus à des erreurs médicales potentielles (18/458 634). Plus de la moitié (52,7%) des 129 patients présentaient des signes vitaux anormaux à la sortie de l'hôpital. La pneumonie (27,1%) était la cause de décès la plus fréquente. Les thèmes des patients étaient les suivants: patient difficile, plaintes multiples, comorbidités multiples, progression aiguë d'une maladie chronique et chutes récurrentes. Les thèmes abordés par les prestataires étaient les suivants: omission de tenir compte de l’étiologie infectieuse, omission d’admettre un patient âgé à haut risque et omission de diagnostic. Les thèmes du système étaient les suivants: visites multiples à l’urgence ou admission récente, et aucun signe vital répété n’a été enregistré. CONCLUSION: Bien que la fréquence des décès liés et imprévus et ceux dus à une erreur médicale soit faible, les cliniciens doivent examiner attentivement les thèmes communs mis en évidence pour les patients, les prestataires et les systèmes afin de faciliter une sortie en toute sécurité des urgences.

Non-fatal strangulation is a dangerous mechanism of injury among survivors of intimate partner violence and sexual assault, with inadequate evidence to guide investigation in the emergency department (ED). The primary objective is to identify the proportion of intimate partner violence and sexual assault where non-fatal strangulation occurs, and to describe the sequelae of injuries.Health records review of patients treated at the Sexual Assault and Partner Abuse Care Program (SAPACP) and/or Trauma Program at a tertiary level hospital between January 2015 and December 2018. Eligible patients were greater than 16 years old, seen by the SAPACP or trauma team for intimate partner violence and sexual assault, and had a non-fatal strangulation injury. Data were abstracted from the standardized assessment completed by the SAPACP nurse. Descriptive statistics were used.We identified 209 eligible cases of non-fatal strangulation, among 1791 patient presentations to the SAPACP. Median patient age was 27 years, and 97.6% were female. Computed tomography (CT) of the head was obtained in 22.5%, and CT angiography (CTA) of the head and neck in 6.2% of cases. Eleven significant injuries were identified. Two cases of vascular abnormalities: internal carotid artery indentation with possible intramural hematoma and possible internal carotid artery dissection. Other injuries included delayed bilateral subdural hematomas, a depressed skull fracture, and six nasal fractures.We found over 10% prevalence of non-fatal strangulation in survivors of intimate partner violence and sexual assault. There was a low rate of clinically important injury on the index ED visit secondary to non-fatal strangulation. Severe injury was primarily secondary to concomitant trauma, and utilization of CTA in this cohort was low. Increased awareness is needed among ED physicians regarding the need to consider CTA head and neck.RéSUMé: CONTEXTE: La strangulation non mortelle est un mécanisme dangereux de blessures chez les survivants de violence conjugale et d’agression sexuelle, avec des preuves insuffisantes pour guider l’enquête aux services d’urgence (SU). L'objectif principal est d'identifier la proportion de violence conjugale et d'agression sexuelle où survient un étranglement non mortel, et de décrire les séquelles des blessures. MéTHODES: Examen des dossiers médicaux des patients traités au programme de soins pour les agressions sexuelles et les abus de partenaires (SAPACP) et/ou au programme de traumatologie d'un hôpital de niveau tertiaire entre janvier 2015 et décembre 2018. Les patients éligibles avaient plus de 16 ans, étaient vus par le SAPACP ou l'équipe de traumatologie pour des violences entre partenaires intimes et des agressions sexuelles, et présentaient une blessure non mortelle par strangulation. Les données ont été extraites de l'évaluation standardisée réalisée par l'infirmière du SAPACP. Des statistiques descriptives ont été utilisées. RéSULTATS: Nous avons identifié 209 cas éligibles de strangulation non fatale, parmi les 1791 présentations de patients au SAPACP. L'âge médian des patients était de 27 ans, et 97,6 % étaient des femmes. La tomodensitométrie (TDM) de la tête était réalisée dans 22,5 % des cas, et l’angiographie TDM de la tête et du cou dans 6,2 % des cas. Onze blessures significatives ont été identifiées. Deux cas d'anomalies vasculaires : indentation de l'artère carotide interne avec possible hématome intramural et possible dissection de l'artère carotide interne. Les autres blessures comprenaient des hématomes sous-duraux bilatéraux retardés, une fracture du crâne déprimée et six fractures nasales. CONCLUSION: Nous avons constaté une prévalence de plus de 10 % de strangulation non mortelle chez les survivants de violence conjugale et d’agression sexuelle. Il y avait un faible taux de blessures cliniquement importantes lors de la visite aux urgences de référence, secondaires à une strangulation non fatale. Les lésions graves étaient principalement secondaires à des traumatismes concomitants, et le recours à l'angiographie dans cette cohorte était faible. Il est nécessaire de sensibiliser davantage les médecins des urgences à la nécessité d'envisager une angioplastie de la tête et du cou.

Introduction/Innovation ConceptEmergency medicine (EM) requires physicians to deal with acutely ill patients in a fast-paced and dynamic environment, which creates a barrier to debriefing after critical events. These unique challenges can negatively impact wellness. We sought to adapt and implement a peer-support wellness program called ‘Ice Cream Rounds’ in an EM residency setting.MethodsA needs assessment survey was conducted among EM residents at The University of Ottawa to gauge interest and obtain resident input regarding program design. The structure of the sessions was adapted from similar initiatives in Canadian Pediatric Residency programs.Curriculum, Tool or MaterialConfidential peer-support sessions were created and piloted. Residents preferred peer facilitators, rather than staff, so two residents obtained training the Faculty of Medicine’s Wellness Program to lead sessions. Attendance at rounds was voluntary; however, overall attendance was recorded along with feedback from pilot sessions. Discussion topics included difficult patient encounters, poor patient outcomes, challenges in residency, and ethical issues. Post implementation feedback demonstrated that Ice Cream Rounds was a helpful forum for residents to discuss important issues with colleagues.ConclusionsThis is the first Canadian EM training program to adapt, implement, and evaluate peer-support wellness rounds for debriefing, and this initiative can be easily adopted by any EM training program.

Objectives. To estimate the population-level frequencies and standardized rates of sexual assault cases in the province of Ontario, Canada. Methods. We conducted a 15-year retrospective analysis (2002–2016) of sexual assault cases by linking 5 provincial administrative health databases. We defined sexual assault by an algorithm of 23 International Classification of Diseases, 10th Revision, and physician billing codes. We calculated age- and sex-stratified standardized rates per 100 000 census population, and we used age- and sex-stratified Poisson regressions to determine annual rate ratios. Results. Between 2002 and 2016, there were 52 780 incident cases of sexual assault in Ontario at a rate of 27.38 per 100 000 population. The highest rates were found among females aged 15 to 19 years (187 per 100 000) and 20 to 24 years (127 per 100 000). Among males, the highest rates were observed among children aged 0 to 4 years (41 per 100 000) and 5 to 9 years (29 per 10 000). Among males and females, the annual rate ratio increased among those aged 15 years and older and decreased among those aged 14 years and younger. Conclusions. Sexual assault was documented across all age groups and sexes, from children to elders, with high standardized rates among adolescents and children.

Emergency departments are a common access point for survivors of sexual and gender-based violence (SGBV), but very little is known about where survivors live and the neighborhoods they return to. The objectives of this study were to describe the patient population that present for a sexual or partner-based assault and explore the geographic distribution of cases across the Ottawa-Gatineau area. Data for this study were extracted from the Sexual Assault and Partner Abuse Care Program (SAPACP) case registry (January 1 to December 31, 2015) at The Ottawa Hospital. Spatial analyses were conducted using six-digit postal codes converted into Canadian Census Tract units to identify geographic areas with concentrated cases of SGBV. Concentrated areas were defined as Census Tracts with seven or more SGBV cases within a single calendar year. In 2015, there were 406 patients seen at the SAPACP and 348 had valid postal codes and were included in the analyses. More than 90% of patients were female and 152 (43.68%) were below 24 years of age. More than 70% knew their assailant and the most common locations of the assault were at the survivors’ home (31.03%), assailants’ home (27.01%), or outdoors (10.92%). Eight concentrated areas were identified including three in the downtown entertainment district, three lower income areas, one high-income neighborhood, and one suburb more than 20 km from downtown. The findings from this study describe the typical clinical presentation of sexual and domestic assault survivors and also challenge geographic stereotypes of where survivors live and what areas of the city are most affected by SGBV. Using residential information provides a survivor-centric approach that highlights the widespread nature of SGBV and supports the need for population-based approaches to improve care for survivors.

ObjectiveThe objectives of this study were to: (1) document violent and controlling behaviours within intimate partnerships during the perinatal period; and (2) determine individual, interpersonal and household-level factors influencing the risk of perinatal intimate partner violence (IPV).DesignCross-sectional survey.SettingThe Ottawa Hospital, Department of Obstetrics and Gynecology, Ottawa, Ontario, Canada.ParticipantsPatients who gave birth at The Ottawa Hospital and were >20 days post partum between 17 March and 16 June 2020.Main outcomes and measuresPerinatal IPV was defined as regular controlling behaviours or act-based forms of emotional/physical/sexual abuse in the 12 months before pregnancy, during pregnancy and/or post partum. Log-binomial multivariable regression models were used to compute adjusted risk ratios (aRRs) and 95% CIs to identify potential risk factors for IPV: maternal age, postpartum depression, parity, increase in partner substance use and household income.ResultsAmong 216 participants, the median maternal age was 33 years (IQR: 30–36). In total, 52 (24.07%) reported some form of perinatal IPV, 37 (17.13%) reported regular controlling behaviour and 9 (4.17%) reported both. Household income below the municipal median was the strongest risk factor for perinatal IPV (aRR: 3.24, 95% CI: 1.87 to 5.59). There was no apparent association between maternal age (aRR: 0.99, 95% CI: 0.94 to 1.04), postpartum depression (aRR: 1.03, 95% CI: 1.00 to 1.07), nulliparity (aRR: 1.18, 95% CI: 0.71 to 1.97) or increases in partner substance use (aRR: 0.73, 95% CI: 0.42 to 1.25) with IPV.ConclusionOne in four individuals in this study experienced perinatal IPV. Household income was the strongest risk factor, and surprisingly, many hypothesised risk factors (eg, mental health, partner substance use, etc) were not significantly associated with perinatal IPV in this sample. This highlights the challenges in both measuring IPV and identifying individuals exposed to perinatal IPV during the high stress of the COVID-19 pandemic.

Introduction: The #MeToo social media movement gained international status in October 2017 as millions disclosed experiences of sexual and intimate partner violence. People who experience violence from a former/current intimate partner may not present for care for many reasons, among them not knowing where to go for care, or not realizing they were experiencing abuse since the behavior was portrayed as ‘normal’. Empirical research identified increased police reporting, internet searches, and new workplace regulations on sexual assault/harassment after #MeToo. Less is known about how #MeToo has influenced hospital-based care, particularly among IPV cases. We aimed to investigate if the #MeToo social movement influenced patterns of IPV cases presenting for emergency care. Methods: This study took place at the Sexual Assault and Partner Abuse Care Program (SAPACP), within the Emergency Department of The Ottawa Hospital. Patients seen from November 1st, 2016 through to September 30th, 2017 was considered Pre-#MeToo and those seen November 1st, 2017 to September 30th, 2018 was considered Post-#MeToo. All patients seen in October 2017 were excluded. Analyses compare the proportion and characteristics of IPV cases seen Pre- and Post-#MeToo. Log-binomial regression models were used to calculate relative risk and 95% CI. Results: 890 cases were seen by the SAPACP during the total study period, of which 564 (63%) were IPV cases. 258 IPV cases were seen Pre-#MeToo and 306 IPV Post-#MeToo. The clinical presentation for IPV cases was similar between both periods where approximately 42% of IPV cases presented for sexual assault, 50% presented for physical assault. An increase in frequency and proportion of IPV cases was observed post-#MeToo. Post-#MeToo there were 48 additional cases of IPV, corresponding to almost a 20% increase in risk compared to the Pre-#MeToo period. (RR: 1.19, 95% CI: 1.07-1.31) Post-#MeToo, there were more presenting cases of IPV among male/trans cases (9 vs 26) and youth cases (82 vs 116). Conclusion: #MeToo is a powerful social movement that corresponded with a significant increase in IPV cases presenting for emergency care. While the assault characteristics among IPV cases remained similar, an important contribution of this research is the increase in youth, male/transgender patients who presented for care post-#MeToo. Continued investigations into pre- post-#MeToo trends is needed to understand more about the changing clinical population and to inform resource and service allocation.

Background: The emergency department (ED) is an at-risk area for medical error. We measured the frequency and characteristics of patients with unanticipated death within 7 days of ED discharge and whether medical error contributed. Aim Statement: This study aimed to calculate the frequency of patients experiencing death within 7 days after ED discharge and determine whether these deaths were related to their index ED visit, were unanticipated, and whether possible medical error occurred. Measures & Design: We performed a single-centre health records review of 200 consecutive cases from an eligible 458,634 ED visits from 2014-2017 in two urban, academic, tertiary care EDs. We included patients evaluated by an emergency physician who were discharged and died within 7 days. Three trained and blinded reviewers determined if deaths were related to the index visit, anticipated or unanticipated, or due to potential medical error. Reviewers performed content analysis to identify themes. Evaluation/Results: Of the 200 cases, 129 had sufficient information for analysis, translating to 44 deaths per 100,000 ED discharges. We found 13 cases per 100,000 ED discharges were related and unanticipated deaths and 18 of these were due to potential medical errors. Over half (52.7%) of 129 patients displayed abnormal vital signs at discharge. Patients experienced pneumonia (27.1%) as their most common cause of death. Patient characteristic themes were: difficult historian, multiple complaints, multiple comorbidities, acute progression of chronic disease, recurrent falls. Provider themes were: failure to consider infectious etiology, failure to admit high-risk elderly patient, missed diagnosis. System themes included multiple ED visits or recent admission, no repeat vital signs recorded. Discussion/Impact: Though the frequency of related and unanticipated deaths and those due to medical error was low, these results highlight opportunities to potentially enhance ED discharge decisions. These data add to the growing body of ED diagnostic error literature and emphasize the importance of identifying potentially high risk patients as well as being cognizant of the common medical errors leading to patient harm.

Background Achieving just outcomes in sexual assault cases is one of the most serious and complex problems facing the healthcare and justice systems. This study was designed to determine the prevalence and correlates of Sexual Assault Evidence Kit (SAEK) completion and release to police among sexual assault cases presenting to the ED. Methods Data for this retrospective study come from the Sexual Assault and Partner Abuse Care Programme (SAPACP) case registry (1 January to 31 December, 2015) at The Ottawa Hospital, a unique medical-forensic access point and the only facility offering SAEK collection in Ottawa. Bivariable and multivariable logistic regression models were conducted using ORs, adjusted ORs (AORs) and 95% CIs. Results In 2015, 406 patients were seen by the SAPACP and 202 (77.1%) were eligible for a SAEK. Among eligible cases, 129 (63.9%) completed a SAEK and 60 (29.7%) released the SAEK to police for investigation. Youth cases (≤24 years) had the highest odds of completing a SAEK (AOR 2.23, 95% CI 1.18 to 4.23). Cases who were uncertain of the assailant (AOR 3.62, 95% CI 1.23 to 10.67) and assaults that occurred outdoors (AOR 3.14, 95% CI 1.08 to 9.09) were most likely to release the SAEK to police. Conclusion Even with access to specialised forensic evidence collection, many sexual assault survivors do not complete a SAEK, and even fewer release the evidence to police for investigation. The ED is a common entry points into the healthcare system, and this study has highlighted the need to strengthen services and reduce attrition along the health-justice continuum.

Introduction Sexual assault is disturbingly common, yet little is known about those occurring at mass gatherings, defined as a group of people congregated for a common purpose. Our objectives were to examine patterns of variation in sexual assault associated with mass gatherings and to determine factors associated with assaults occurring at mass gatherings. Methods We performed a case series analysis from January to December, 2013. We included all patients >16 years presenting within 30 days of their sexual assault to the Ottawa Hospital Sexual Assault and Partner Abuse Care Program (SAPACP). Cases were stratified by whether or not they occurred at mass gatherings. We abstracted from the SAPACP records: patient and sexual assault characteristics, alcohol or drug consumption and medical and forensic care accepted. We performed descriptive analyses and multiple logistical regression to identify factors associated with mass gathering assaults. Results We found 204 cases of sexual assault, of which 53 (26%) occurred at mass gatherings. Relative frequencies of mass gathering sexual assaults peaked during New Year9s Eve, Canada Day, university frosh week and Halloween. We found the following factors were statistically significantly associated with sexual assault at mass gatherings: younger age (OR=0.95, 95% CI 0.91 to 0.99); voluntary consumption of drugs and alcohol (3.88, 95% CI 1.34 to 11.23); assault occurring on a holiday (2.37, 95% CI 1.00 to 5.64) and the assailant unknown to the victim (2.43, 95% CI 1.15 to 5). Interpretation This study is the first to describe patterns of variation in sexual assault incidents associated with occurrence of mass gatherings as well as factors associated with such assaults. We will disseminate these results to key stakeholders in order to develop prevention-minded policies for future mass gatherings.

Background/objectives Due to perceived increased tolerability and compliance, and decreased cost, recent trends in practice are moving towards using fewer drugs for HIV post-exposure prophylaxis. However, there is limited literature to assess this is in the North American sexual assault victim population. Methods This retrospective before-and-after cohort study compared patients seen at a sexual assault care facility before and after the introduction of two and three-drug post-exposure prophylaxis regimens. Our primary outcome was completion of the 28-day regimen. Secondary objectives included HIV seroconversion rates and patient reported side effects. Results Six-hundred-thirty charts from a 2-year period were reviewed, and 429 met inclusion criteria. There was no difference in completion rates of post-exposure prophylaxis between the two cohorts (50.5% vs. 51.6%). However, there were fewer reported side effects (72.2% vs. 17.6%) in the later cohort. We subsequently compared all patients in either cohort who received four-drug therapy (N = 128) versus those who received two or three-drug regimens (N = 47). The two or three-drug regimen group had a higher completion rate (66.0% vs. 42.2%; p = 0.03), and a lower rate of reported side effects (19.1% vs. 53.9%), specifically for nausea (12.8% vs. 36.7%), constipation (0% vs. 7.9%), diarrhea (2.1% vs. 21.1%), mood changes (0% vs. 10.9%), headache (2.1% vs. 16.4%), and fatigue (6.4% vs. 26.6%). There were no HIV seroconversions in either group. Conclusion Two and three-drug HIV post-exposure prophylaxis regimens are better tolerated by patients and associated with greater compliance than four-drug therapy, and could be considered in the sexual assault victim population.

Introduction: Achieving just outcomes in sexual assault cases is one of the most serious and complex problems facing the health care and justice systems. The objectives of this analysis were to determine the prevalence and correlates of Sexual Assault Evidence Kit (SAEK) completion and release to police among sexual assault cases presenting at the hospital emergency department. Methods: Data for this cross-sectional study come from the Sexual Assault and Partner Abuse Care Program (SAPACP) case registry (Jan1-Dec31, 2015) at The Ottawa Hospital, a unique medical-forensic access point and the only facility offering SAEK collection in Ottawa. Bivariable and multivariable logistic regression models were conducted using odds ratios (OR), adjusted ORs, and 95% confidence intervals (CI). Results: In 2015 406 patients were seen by the SAPACP and 202 (77.10%) were eligible for a SAEK. Among eligible cases, 129 (63.86%) completed a SAEK and only 60 (29.70%) released the SAEK to police for investigation. Youth cases below 24 years of age (AOR:2.23, 95% CI: 1.18-4.23) and presenting within 24h (AOR:0.93-3.40) were the strongest independent factors contributing to SAEK completion. Cases who were uncertain of the assailant (AOR:3.62, 95% CI:1.23-10.67) and assaults that occurred outdoors (AOR:3.14, 95% CI:1.08-9.09) were the cases most likely to release the SAEK to police. Conclusion: Our study has shown high attrition levels along the continuum of care and justice for sexual assault case. Even with access to specialized forensic evidence collection, many do not complete a SAEK and even fewer release the evidence to police for legal investigation.

Introduction: Emergency Departments are a common point of access for survivors of sexual and gender-based violence (SGBV), but very little is known about where survivors live and the characteristics of the neighbourhoods. The objective of this study was to use hospital-based data to characterize sexual and domestic assault cases and identify geographic distribution across the Ottawa-Gatineau area. Methods: Data for this study were extracted from the Sexual Assault and Partner Abuse Care Program (SAPACP) case registry (Jan 1-Dec 31, 2015) at The Ottawa Hospital. Spatial analyses were conducted using 6-digit postal codes converted to Canadian Census Tracts to identify potential geographic areas where SGBV cases are clustered. Hot-spots were defined as Census Tracts with seven or more assaults within a single calendar year.Data for this study were extracted from the Sexual Assault and Partner Abuse Care Program (SAPACP) case registry (Jan 1-Dec 31, 2015) at The Ottawa Hospital. Spatial analyses were conducted using 6-digit postal codes converted to Canadian Census Tracts to identify potential geographic areas where SGBV cases are clustered. Hot-spots were defined as Census Tracts with seven or more assaults within a single calendar year. Results: In 2015, there were 406 patients seen at the SAPACP, 348 had valid postal codes from Ottawa-Gatineau and were included in the analyses. Over 90% of patients were female and 152 (43.68%) were below 24 years of age. Eight hot-spots were identified including 3 in the downtown entertainment district, 3 lower income areas, 1 high income neighbourhood, and 1 suburb more than 20km from downtown. Conclusion: This study is of the first to use hospital-based data to examine the geographic distribution of SGBV cases, with key findings including the identification of high-income neighbourhoods and suburbs as SGBV hot-spots. Alongside efforts like the #MeToo movement, this evidence challenges stereotypes of assault survivors and highlights the breadth and widespread nature of SGBV.

Introduction: Domestic violence (DV) and sexual assault (SA), together called sexual and gender-based violence (SGBV), are traumatic and life-changing events. Post-assault follow-up care is essential for survivor recovery through medical care, mental health functioning, and injury reassessment. The objective of this analysis was to determine the frequency of loss to follow-up (LTFU) in a SGBV population, and the characteristics most commonly associated with LTFU. Methods: The Sexual Assault and Partner Abuse Care Program (SAPACP) is the only Ottawa program for emergency/forensic care. Demographic and assault characteristics were abstracted from the SAPACP clinical case registry (1 Jan 2015 to 20 Dec 2017). Descriptive analyses and bivariable/multivariable logistic regression modelling assessed factors most strongly associated with LTFU using odds ratios (OR), adjusted OR (AOR), and 95% confidence intervals (CI). Results: Among 894 initial SAPACP visits, 482 (53.9%) were LTFU. Of those LTFU, 445 (92.3%) were female, 185 (38.4%) arrived by ambulance, 284 presented acutely (58.9%), 70 (14.5%) had substance use issues, and 82 (17.0%) were re-victimized. There were 229 (47.5%) sexual assaults, 201 (41.7%) physical assaults, and 92 (19.1%) verbal assaults. LTFU patients were more likely to arrive by ambulance (AOR: 1.09, 95% CI: 1.34-2.69), experience re-victimization (AOR: 1.94, 95% CI: 1.25-3.03), and have a substance use disorder (AOR: 1.67, 95% CI:1.02-2.73). Those more likely to attend follow-up included sexual assault survivors (AOR: 0.37, 95% CI: 0.27-0.50) and acute presenters (AOR: 0.58, 95% CI: 0.44-0.78). Conclusion: Over half of patients arriving for initial SAPACP visits did not follow-up. LTFU was more likely among cases that arrived by ambulance, and those involving revicitimization or substance use disorders. Follow-up is critical for maintaining mental and physical health post-trauma. While some characteristics increased follow-up likelihood, this study has identified groups that need attention to reduce LTFU.

Introduction: It is assumed that sexual assault cases presenting at Emergency Departments (ED) are frequently lost to follow-up and should be considered an eligible population for presumptive antimicrobial treatment of sexual transmitted infections (STIs) at initial assessment without lab confirmation. With the growing burden of antibiotic resistance, antimicrobial stewardship guidelines caution against this practice. Among sexual assault cases, our study evaluated STI prevalence, follow-up and retention patterns, and described the prevalence of STI presumptive treatment. Methods: The Sexual Assault and Partner Abuse Care Program (SAPACP) at The Ottawa Hospital is the only program in Ottawa offering emergency and forensic care for survivors of sexual assault and domestic violence. Descriptive statistics were used to summarize information on demographics, clinical presentation, STI testing and results using data from the SAPACP case registry (January 1 - December 31, 2015). Results: Among the 406 patients seen by the SAPACP, there were 262 (64.5%) sexual assault cases that were included in this analysis. STI testing was completed for 209 (79.8%) patients at the initial visit, 90 (43.1%) completed via urine nucleic acid testing (NAAT), 140 (67.0%) via culture swab and 20 (9.6%) via both. Laboratory results detected no cases of gonorrhea, 8 (3.8%) cases of chlamydia, 33(15.8%) cases of bacterial vaginosis (BV), 17 (8.1%) cases of yeast vaginitis and 16 (7.7%) indeterminate testing results. Antimicrobial STI presumptive treatment was given to 12 (5.7%) patients at the time of their initial visit prior to lab confirmation. Patient follow-up occurred in 172 (82.3%) patients, with all chlamydia cases treated. Of the 37 (17.7%) patients lost to follow up, 9 were positive for BV, 1 was positive for yeast and 10 were indeterminate, all of which may be underlying vaginal flora. Follow up testing/test of cure was completed in 91 (52.9%) of patients, with 4 (2.3%) positive results, all of which were BV. Conclusion: In our ED, up to 15.8% of sexual assault patients had at least one laboratory confirmed STI and over 80% of all patients returned for follow-up. Our results show that it is safe and effective to only treat STI screen positive cases at follow-up, reducing the frequency of presumptive antimicrobial STI treatment. Benefits of this strategy include decreased patient side effects, cost savings and better antimicrobial stewardship.

Introduction: Intimate partner violence (IPV) is a serious public health concern with complex medico-legal implications and a wide range of morbidity. While the ED is often the primary access point for these patients, IPV is under-recognized. Our objectives were to describe the characteristics of female IPV patients in the ED and determine the assessment and management patterns of physicians at a tertiary care academic ED. Methods: We conducted a health records review of adult (>18years) female patients seen at a tertiary care hospital ED presenting with evidence of IPV from January to September 2016. A combined search strategy of hospital records and Sexual Assault and Partner Abuse Care Program (SAPACP) patient rosters was used to identify study subjects. Data were collected for patient demographic/presenting characteristics, assault characteristics, and patterns of referral, management and patient disposition/discharge. Descriptive statistics were generated. Results: 100 patients met inclusion criteria with; mean age 35.1, female 100.0%, arrival by ambulance 53.0%, and mean CTAS level of 2.4. Abuse screening was completed at triage only 24.0% of the time. Presenting complaints were varied, with the most common being injury or trauma (32.0%). Most patients were only identified from the SAPACP roster. Patients reported strangulation, a strong predictor of future homicide, in 34.0% of cases. Admission to hospital occurred in 7.0% of cases with 19.0% involving specialist consultation and 7.0% leaving against medical advice or without being seen. Legal interactions including police involvement occurred 72.0% of the time and Childrens Aid Society was involved in 26.0% of cases. The final diagnosis was recorded as IPV or equivalent in only 49.0% of cases; the remainder were discharged with a final diagnosis of injury/trauma (26.0%), sexual assault (6.0%), somatic complaint (6.0%), mental health (8.0%), substance use/abuse (3.0%) or other (2.0%). Conclusion: Our study highlights that IPV is a common and heterogeneous entity with a wide spectrum of presentations and morbidity. Strangulation rates were high and are associated with increased risk of homicide. IPV is currently under-recognized and continues to carry stigma as ER physicians only recorded a discharge diagnosis of IPV or equivalent in half of cases. Educational strategies are required to highlight the importance of IPV to ED staff.

Introduction: Many survivors of sexual and domestic assault return to violent environments following post-assault care. The objective of this study was to estimate the annual prevalence of revictimization and examine factors associated with return emergency department (ED) visits following their initial encounter for sexual or domestic assault. Methods: The Sexual Assault and Partner Abuse Care Program (SAPACP) at The Ottawa Hospital is the only program in Ottawa offering emergency and forensic care for survivors of sexual assault and domestic violence. Information on demographics, assailant characteristics and clinical presentation were extracted from the SAPACP case registry (January 1 2015- January 31 2016). We conducted descriptive analyses to describe the study sample, and bivariable and multivariable logistic regression modelling to assess factors most strongly associated with revictimization using odds ratios (OR), adjusted OR (AOR) and 95% confidence intervals (CI). Results: Among 377 unique patients seen at the SAPACP, there were 409 encounters for sexual and domestic violence. There were 24 revictimization cases (6.4%) with the number of repeat visits ranging from 2-6. There were 343 (91.0%) female patients and 182 (48.3) under the age of 25. There were 243 (64.5%) sexual assaults, 125 (33.2%) physical assaults, and 42 (11.1%) verbal assaults. Compared to patients who presented once, revictimized patients were more likely to have experienced violence from a current or former intimate partner (AOR:3.02, 95% CI:1.24-7.34), have a substance use disorder (AOR:5.57, 95% CI:2.11-14.68), and were more likely to be taking anti-depressants (AOR:3.34, 95% CI:1.39-8.01). Conclusion: This study has identified a high prevalence of revictimization, with some clients being revictimized as many as 6 subsequent times. Key factors to help identify patients at risk of revictimization are assaults by intimate partners, having substance use problems, and being on antidepressants. Reducing revictimization and preventing further violence is a critical component of care to ensure survivors are safe following their ED encounter.

Introduction: Although Tenofovir/Emtricitabine was approved in 2012 as a single-agent regimen for pre-exposure prophylaxis, there have been no studies to our knowledge that demonstrate the efficacy of single and dual agent regimens in post-exposure prophylaxis. Our goal was to compare outcomes of post-exposure prophylaxis with single and dual agent regimens versus triple therapy in victims of sexual assault. Methods: This was a before and after cohort study of patients seen by the Sexual Assault and Partner Abuse Care Program (SAPACP) at the Ottawa Hospital. We reviewed charts of patients seen by the SAPACP from Jan. 1-Dec. 31 2013, when triple therapy was usual care, and Jan. 1-Dec. 31 2015, after the introduction of alternative regimens. Patients who were deemed high risk or who did not get initial treatment at the SAPACP were excluded. Our primary outcome was the number of patients who completed the entire 28-day post-exposure prophylaxis regimen. Secondary objectives were to assess HIV seroconversion rates and patient reported side effects. Results: Six hundred-thirty charts were reviewed, and 429 were included in the study. Baseline characteristics were similar between the two years. We found no significant difference in completion rates of HIV post-exposure prophylaxis between the two cohorts (50.5% vs. 51.6%). However, we did note a decrease in reported side effects in the 2015 cohort (72.2% vs. 17.6%, pConclusion: Our results suggest that single and dual agent HIV post-exposure prophylaxis regimens are better tolerated by patients and associated with higher rates of completion than triple therapy, and should be considered as stand-alone therapy in the sexual assault victim population.

Introduction/Innovation Concept: Emergency Medicine (EM) is a specialty that requires physicians to deal with acutely ill patients in a fast-paced environment, which can create stress, mental exhaustion and burnout. Continually changing working teams in the Emergency Department does not always allow appropriate debriefing for difficult patient encounters and outcomes on shift. To address these challenges, we sought to adapt and implement a peer-support rounds called ‘Ice Cream Rounds’ used in some Pediatric training programs for an EM training program. Methods: CCFP and Royal College EM residents were surveyed to determine interest and need for Ice Cream Rounds. Of the 31/50 respondents, 87% (26/31) identified their co-residents as their main source of support after difficult patient encounters and 71% (22/31) felt that current opportunities to debrief after difficult experiences were only “sometimes” or “rarely” adequate. Overall, 84% (26/31) were interested in attending Ice Cream Rounds. Residents expressed that they did not want staff present for Ice Cream Rounds so two residents (SCS and TK) obtained training to lead peer-support sessions from The Faculty of Medicine Wellness Program. Attendance at rounds was voluntary and the EM program provided funding for refreshments. Two Ice Cream Rounds were piloted. Attendance and feedback was recorded from pilot sessions. Curriculum, Tool, or Material: Resident-only, peer-run confidential debriefing sessions. Sessions were voluntary and lasted one hour. Approximately 20-30/50 residents attended each Ice Cream Rounds. Discussions were confidential but include topics such as difficult patient encounters, poor patient outcomes, challenges in residency, and ethical issues. In response to positive attendance and feedback, the EM program provided 3-4 one-hour protected time slots with a stipend for refreshments for future academic years. Comments from residents consistently reaffirmed that Ice Cream Rounds was a helpful forum to discuss important issues with colleagues and provided a safe and confidential resource to help cope with residency challenges. Conclusion: We adapted, implemented, and evaluated a novel Peer-Support Wellness Rounds for debriefing resident issues and difficult patient encounters in a EM training program. To our knowledge this is the first Canadian initiative to implement such rounds in an EM training program. We believe that this template can be easily adopted by any EM training program and will effectively address wellness challenges faced by residents during their training.

Examination and management of the sexually assaulted patient comprise a complex task. On-call nurses with advanced training are used in some hospitals, but their impact on patient care and appropriate forensic examination is largely unknown. We evaluated the impact of the introduction of a sexual assault/domestic violence program (SADVP) on ED flow, comprehensive patient care, and collection of forensic evidence.Patients presenting to the 2 emergency departments in the Kingston area (Ontario, Canada) (population, 250,000) after sexual assault were compared during 2 time periods: (1) before SADVP implementation (January 2001 through August 2004) and (2) after SADVP implementation (September 2004 to August 2006). ED, hospital discharge, SADVP, and police records were reviewed. Data abstraction included patient demographics, assault characteristics, forensic examination results, and treatment protocols.The incidence of patients presenting with a complaint of sexual assault doubled (61 cases before SADVP implementation and 92 cases after SADVP implementation). Median times to initial clinical evaluation were lower in the post-SADVP group (20 minutes vs 33 minutes, P = .04). Patients in the post-SADVP group reported less vaginal/anal penetration (77% vs 98%, P.001) and had fewer genital injuries (13% vs 39%, P = .007); other sexual assault characteristics were similar between the 2 study periods. Forensic kits were completed more often in the post-SADVP group (77% vs 66%, P = .18). Pregnancy and sexually transmitted disease prophylaxis was offered more consistently after SADVP implementation (98% vs 85%, P = .007), as was counseling (100% vs 95%, P = .06).The profile of patients observed after SADVP implementation changed to include less stereotypical sexual assaults. Introduction of the SADVP decreased wait times for sexually assaulted patients, despite the need for the on-call nurses to attend the emergency department. This program also showed higher completion on a number of important indicators of quality of care: forensic kits, counseling, and pregnancy and sexually transmitted disease prophylaxis.

Primary human fibroblasts have a finite replicative lifespan in culture that culminates in a unique state of growth arrest, termed senescence that is accompanied by distinct morphological and biochemical alterations. Senescent cell responses to extracellular stimuli are believed to be altered at a point after receptors are bound by ligand, leading to improper integration of the signals which initiate DNA replication. In this study we demonstrate that one of the key organizing membrane microdomains for receptor signaling, caveolae, are absent in senescent cells. A comparison of young and senescent cells indicated that senescent cells contained a higher total amount of caveolins 1 and 2 but had significantly less of both proteins in the caveolar fraction. Additionally, caveolar fractions from senescent cells completely lacked the tyrosine-kinase activity associated with functional caveolae. Furthermore, old cells had little caveolar protein exposed to the outer plasma membrane as estimated by using an in vivo biotinylation assay and no detectable caveolin 1 on the cell surface when processed for immunofluoresence and confocal microscopy. Together, these data suggest that a fundamental loss of signal integration at the plasma membrane of senescent cells is due to the loss of signaling competent caveolae. J. Cell.
