Abstract
Introduction High levels of immunity to SARS-CoV-2 in the community correlate with protection from COVID-19 illness. Measuring COVID-19 antibody seroprevalence and persistence may elucidate the level and length of protection afforded by vaccination and infection within a population. Methods We measured the duration of detectable anti-spike antibodies following COVID-19 vaccination in a multistate, longitudinal cohort study of almost 13,000 adults who completed daily surveys and submitted monthly dried blood spots collected at home. Results Overall, anti-spike antibodies persisted up to 284 days of follow-up with seroreversion occurring in only 2.4% of the study population. In adjusted analyses, risk of seroreversion increased with age (adults aged 55-64: adjusted hazard ratio [aHR] 2.19 [95% confidence interval (CI): 1.22, 3.92] and adults aged > 65: aHR 3.59 [95% CI: 2.07, 6.20] compared to adults aged 18-39). Adults with diabetes had a higher risk of seroreversion versus nondiabetics (aHR 1.77 [95% CI: 1.29, 2.44]). Decreased risk of seroreversion was shown for non-Hispanic Black versus non-Hispanic White (aHR 0.32 [95% CI: 0.13, 0.79]); college degree earners versus no college degree (aHR 0.61 [95% CI: 0.46, 0.81]); and those who received Moderna mRNA-1273 vaccine versus Pfizer-BioNTech BNT162b2 (aHR 0.35 [95% CI: 0.26, 0.47]). An interaction between healthcare worker occupation and sex was detected, with seroreversion increased among male, non-healthcare workers. Conclusion We established that a remote, longitudinal, multi-site study can reliably detect antibody durability following COVID-19 vaccination. The survey platform and measurement of antibody response using at-home collection at convenient intervals allowed us to explore sociodemographic factors and comorbidities and identify predictors of antibody persistence, which has been demonstrated to correlate with protection against disease. Our findings may help inform public health interventions and policies to protect those at highest risk for severe illness and assist in determining the optimal timing of booster doses.Clinical trials registry: NCT04342884.

Abstract
INTRODUCTION Vaccine hesitancy presents a challenge to COVID-19 control efforts. To identify beliefs associated with delayed vaccine uptake, we developed and implemented a vaccine hesitancy survey for the COVID-19 Community Research Partnership. METHODS In June 2021, we assessed attitudes and beliefs associated with COVID-19 vaccination using an online survey. Self-reported vaccination data were requested daily through October 2021. We compared responses between vaccinated and unvaccinated respondents using absolute standardized mean differences (ASMD). We assessed validity and reliability using exploratory factor analysis and identified latent factors associated with a subset of survey items. Cox proportional hazards models and mediation analyses assessed predictors of subsequent vaccination among those initially unvaccinated. RESULTS In June 2021, 29,522 vaccinated and 1,272 unvaccinated participants completed surveys. Among those unvaccinated in June 2021, 559 (43.9 %) became vaccinated by October 31, 2021. In June, unvaccinated participants were less likely to feel "very concerned" about getting COVID-19 than vaccinated participants (10.6 % vs. 43.3 %, ASMD 0.792). Among those initially unvaccinated, greater intent to become vaccinated was associated with getting vaccinated and shorter time to vaccination. However, even among participants who reported no intention to become vaccinated, 28.5 % reported vaccination before study end. Two latent factors predicted subsequent vaccination-being 'more receptive' was derived from motivation to protect one's own or others' health and resume usual activities; being 'less receptive' was derived from concerns about COVID-19 vaccines. In a Cox model, both factors were partially mediated by vaccination intention. CONCLUSION This study characterizes vaccine hesitant individuals and identifies predictors of eventual COVID-19 vaccination through October 31, 2021. Even individuals with no intention to be vaccinated can shift to vaccine uptake. Our data suggest factors of perceived severity of COVID-19 disease, vaccine safety, and trust in the vaccine development process are predictive of vaccination and may be important opportunities for ongoing interventions.

Abstract
BACKGROUND Monitoring the effectiveness of COVID-19 vaccines against SARS-CoV-2 infections remains important to inform public health responses. Estimation of vaccine effectiveness (VE) against serological evidence of SARS-CoV-2 infection might provide an alternative measure of the benefit of vaccination against infection. METHODS We estimated mRNA COVID-19 vaccine effectiveness (VE) against development of SARS-CoV-2 anti-nucleocapsid antibodies in March-October 2021, during which the Delta variant became predominant. Participants were enrolled from four participating healthcare systems in the United States, and completed electronic surveys that included vaccination history. Dried blood spot specimens collected on a monthly basis were analyzed for anti-spike antibodies, and, if positive, anti-nucleocapsid antibodies. We used detection of new anti-nucleocapsid antibodies to indicate SARS-CoV-2 infection, and estimated VE by comparing 154 case-participants with new detection of anti-nucleocapsid antibodies to 1,540 seronegative control-participants matched by calendar period. Using conditional logistic regression, we estimated VE ≥ 14 days after the 2nd dose of an mRNA vaccine compared with no receipt of a COVID-19 vaccine dose, adjusting for age group, healthcare worker occupation, urban/suburban/rural residence, healthcare system region, and reported contact with a person testing positive for SARS-CoV-2. RESULTS Among individuals who completed a primary series, estimated VE against seroconversion from SARS-CoV-2 infection was 88.8% (95% confidence interval [CI], 79.6%-93.9%) after any mRNA vaccine, 87.8% (95% CI, 75.9%-93.8%) after BioNTech vaccine and 91.7% (95% CI, 75.7%-97.2%) after Moderna vaccine. VE was estimated to be lower ≥ 3 months after dose 2 compared with < 3 months after dose 2, and among participants who were older or had underlying health conditions, although confidence intervals overlapped between subgroups. CONCLUSIONS VE estimates generated using infection-induced antibodies were consistent with published estimates from clinical trials and observational studies that used virologic tests to confirm infection during the same period. Our findings support recommendations for eligible adults to remain up to date with COVID-19 vaccination.

Abstract
Abstract
Background
We characterize the incidence and risk factors of SARS-CoV-2 breakthrough infections in the NC-CCRP.
Cumulative Incidence of Breakthrough infections after Self-reported Symptomatic SARS-CoV-2 Test
Cumulative incidence curves (1 minus the unadjusted Kaplan–Meier risk), number at risk at each time point for the first self-reported symptomatic positive SARS-CoV-2 test, starting from full vaccination among participants who reported full vaccination.
Methods
The NC-CCRP is an observational cohort study assessing COVID-19 symptoms, test results, vaccination status, and risk behavior via daily email or text surveys. Cox models were used to estimate hazard rates. Fixed covariates were age at enrollment, race/ethnicity, sex, county of residence classification, vaccine product, and healthcare worker status. Time varying covariates were vaccination rate in county of residence, mask usage in the week prior, the Delta time frame, the Omicron time frame, and receipt of a vaccine booster.
Results
Among 15,808 eligible adult participants, 638 (4.0%) reported a positive SARS-CoV-2 test after vaccination from 01/15/2021 to 01/03/2022. The breakthrough rate increased with time from vaccination (Figure), with a cumulative incidence of 6.95% over 45 weeks of follow-up. Factors associated with a lower risk of breakthrough infection (p< 0.05) included older age (HR 0.7 for participants 45-64 years and 0.41 for those > 65 years compared to those 18-44 years), prior SARS-CoV-2 infection (HR 0.58), higher rates of mask use (HR 0.66), and receipt of a booster vaccination (HR 0.33). Higher rates of breakthrough infection were reported by participants vaccinated with BNT162b2 (HR 1.35) or Ad26.COV2.S (1.74) compared to mRNA-1273, those residing in suburban (HR 1.33) or rural (1.24) counties compared to urban counties, and during circulation of the Delta (3.54) and Omicron (16.68) variants compared to earlier time periods. There was no association of breakthrough infection with sex, race/ethnicity, healthcare worker status, or vaccination rate in the county of residence.
Conclusion
In this real-world analysis, risk of breakthrough infections increased with time since vaccination, with some variability among the specific vaccine products. Risk increased dramatically during the Omicron surge. Higher rates among younger individuals may reflect more frequent, or higher risk exposures, including those related to childcare. Significantly lower rates of breakthrough associated with mask wearing and receipt of a booster highlight specific measures that individuals can take to minimize the risk for COVID-19.

Abstract
Background Wearing a face mask is a primary public health method to reduce SARS-CoV-2 transmission. We assessed the association between self-reported mask use and risk of COVID-19 infection during three periods of the pandemic. Methods We performed a nested case-control analysis within the NC-CCRP of adults ≥18 years who completed daily syndromic surveillance surveys from April 2020 through February 2022, comparing self-reported cases to controls who never self-reported a positive test. We matched up to 10 controls to each case on calendar time of self-reported positive test and corresponding daily survey entry. Not wearing a mask was defined as responding “no” at least once in the ten days preceding the match date to “In the last 24 hours, have you worn a face mask or face covering every time you interacted with others (not in your household) within a distance of less than 6 feet?” Conditional logistic regression models of risk of COVID-19 infection were adjusted for demographics, vaccination status, and recent known exposure to COVID-19. We tested any days not wearing a mask during the Pre-Delta (July 1 2020-June 30, 2021), Delta (July 1– November 30, 2021), and Omicron (December 1, 2021 – February 28, 2022) periods. Results Among 3,901 cases and 27,813 date-matched controls, there was a significant interaction between mask use and time period (p< 0.001). Prior to July 2021, the odds of a reported SARS-CoV-2 infection was 66% higher (aOR=1.66, 95% CI=1.43 – 1.91) among participants reporting at least one day not wearing a mask compared to those who reported no days (1592 cases, 11717 controls). During the Delta-predominant period, the results were similar (aOR=1.53, 95% CI=1.23 – 1.89; 659 cases, 4649 controls). This association was attenuated during the Omicron-predominant period, where the odds of a reported SARS-CoV-2 infection was 16% higher (aOR=1.16, 95% CI=1.03 – 1.32; 1563 cases, 10960 controls). Conclusion While the effect of not wearing a mask remains significant, during the Omicron-predominant period we observed a decrease in the association between self-reported mask wearing and risk of SARS-CoV-2 infection. The increased transmissibility of Omicron, pandemic fatigue, and increasing population immunity are possible contributing factors. Disclosures Michael S.

Abstract
The COVID-19 Community Research Partnership (CCRP) is a multisite surveillance platform designed to characterize the epidemiology of the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-COV-2) pandemic. This article describes the CCRP study design and methodology. The CCRP includes two prospective cohorts, one with six health systems in the mid-Atlantic and southern USA, and the other with six health systems in North Carolina. With enrollment beginning in April 2020, sites invited persons within their healthcare systems as well as community members to participate in daily surveillance for symptoms of COVID-like illnesses, testing, and risk behaviors. Participants with electronic health records (EHRs) were also asked to volunteer data access. Subsets of participants, representative of the general population and including oversampling of populations of interest, were selected for repeated at-home serology testing. By October 2021, 65 739 participants (62 261 adult and 3478 pediatric) were enrolled, with 89% providing syndromic data, 74% providing EHR data, and 70% participating in one of the two serology sub-studies. An average of 62% of the participants completed a daily survey at least once a week, and 55% of the serology kits were returned. The CCRP provides rich regional epidemiologic data and the opportunity to more fully characterize the risks and sequelae of SARS-CoV-2 infection.

Abstract
We characterize the overall incidence and risk factors for breakthrough infection among fully vaccinated participants in the North Carolina COVID-19 Community Research Partnership cohort. Among 15,808 eligible participants, 638 reported a positive SARS-CoV-2 test after vaccination. Factors associated with a lower risk of breakthrough in the time-to-event analysis included older age, prior SARS-CovV-2 infection, higher rates of face mask use, and receipt of a booster vaccination. Higher rates of breakthrough were reported by participants vaccinated with BNT162b2 or Ad26.COV2.S compared to mRNA-1273, in suburban or rural counties compared to urban counties, and during circulation of the Delta and Omicron variants.

Abstract
Wearing a facemask can help to decrease the transmission of COVID-19. We investigated self-reported mask use among subjects aged 18 years and older participating in the COVID-19 Community Research Partnership (CRP), a prospective longitudinal COVID-19 surveillance study in the mid-Atlantic and southeastern United States. We included those participants who completed ≥5 daily surveys each month from December 1, 2020 through August 31, 2021. Mask use was defined as self-reported use of a face mask or face covering on every interaction with others outside the household within a distance of less than 6 feet. Participants were considered vaccinated if they reported receiving ≥1 COVID-19 vaccine dose. Participants (n = 17,522) were 91% non-Hispanic White, 68% female, median age 57 years, 26% healthcare workers, with 95% self-reported receiving ≥1 COVID-19 vaccine dose through August 2021; mean daily survey response was 85%. Mask use was higher among vaccinated than unvaccinated participants across the study period, regardless of the month of the first dose. Mask use remained relatively stable from December 2020 through April (range 71-80% unvaccinated; 86-93% vaccinated) and declined in both groups beginning in mid-May 2021 to 34% and 42% respectively in June 2021; mask use increased again since July 2021. Mask use by all was lower during weekends and on Christmas and Easter, regardless of vaccination status. Independent predictors of higher mask use were vaccination, age ≥65 years, female sex, racial or ethnic minority group, and healthcare worker occupation, whereas a history of self-reported prior COVID-19 illness was associated with lower use.

Abstract
OBJECTIVE The aim of the study was to determine the impact of dual-task conditions on mobility after mild traumatic brain injury. DESIGN Eleven adults with mild traumatic brain injury within 1 wk of injury and 10 age- and sex-matched healthy controls completed gait trials with a single-task condition and three separate dual-task conditions: counting by 1 (low), serial subtraction by 3 (medium), and alternating letters and numbers (high). Dual-task cost was calculated as dual-task cost = ([dual-task performance] - [single-task performance]) / [single-task performance] × 100%. RESULTS Participants with mild traumatic brain injury ambulated slower than control subjects (P < 0.001). Significant differences in dual-task cost were noted for both group (P < 0.001) and dual-task condition (P = 0.005). Dual-task cost was greater for those with mild traumatic brain injury compared with controls with significant group differences for the low and high cognitive loads (P < 0.05). Only 1 of the 11 individuals with mild traumatic brain injury and 1 of the 10 controls demonstrated gait speed less than 80 cm/sec, which is predictive of community mobility, during any dual-task condition. Dual-task cost exceeded 11.9%, previously determined to be the minimal detectable change in healthy adults, for 9 of the 11 individuals with mild traumatic brain injury compared with 3 of the 10 controls. CONCLUSIONS Dual-task cost may be a more sensitive measure for impairment during dual-task conditions than gait speed after mild traumatic brain injury.

Abstract
OBJECTIVE This study aimed to assess the agreement between patients presenting to the pediatric emergency department (ED) with acute pain and their caregivers when using the Wong-Baker FACES (WBF) and Faces Pain Scale-Revised (FPS-R). METHODS This was a prospective, observational study examining patients 3 to 7.5 years old presenting to a pediatric ED with acute pain. Participants completed the WBF and FPS-R twice during their ED evaluation. Caregivers rated their child's pain using both the WBF and FPS-R at the same time points. Intraclass correlations (ICCs) were calculated between caregiver and child reports at each time point, and Bland-Altman plots were created. RESULTS Forty-six subjects were enrolled over 5 months. Mean age was 5.5 ± 1.2 years. Average initial child pain scores were 6.6 ± 2.8 (WBF) and 6.1 ± 3.3 (FPS-R), and repeat scores were 3.3 ± 3.4 (WBF) and 3.1 ± 3.3 (FPS-R). Average initial caregiver pain scores were 6.3 ± 2.4 (WBF) and 6.2 ± 2.3 (FPS-R), and repeat scores were 3.4 ± 2.0 (WBF) and 3.4 ± 2.1 (FPS-R). On initial assessment, ICCs between children and caregivers using the FPS-R and WBF were 0.33 and 0.22, respectively. On repeat assessment, the ICCs were 0.31 for FPS-R and 0.26 for WBF. Bland-Altman plots showed poor agreement but no systematic bias. CONCLUSION There was poor agreement between caregivers and children when using the WBF and FPS-R for assessment of acute pain in the ED. Caregiver report should not be used as a substitute for self-report of pain if possible.

Abstract
INTRODUCTION Road traffic collisions (RTCs) are an important public health problem in low and middle-income countries (LMIC), where 90% of RTC deaths occur. The World Health Organization has suggested strategies to address excess mortality from RTCs including efforts to combat driving after using alcohol or drugs. Data on the impact of drug and alcohol use on RTCs is limited in many low-resource settings including Tanzania. We sought to examine the prevalence of drug and alcohol use in Tanzanian RTC drivers. METHODS This prospective, observational study was conducted in the emergency centre (EC) of Muhimbili National Hospital (MNH) in Dar es Salaam, Tanzania. We enrolled adult drivers presenting within 24 h of an RTC. We collected a saliva test of blood alcohol content (BAC) and a urine drug screen (UDS) and administered a validated substance use disorder screening tool, the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST). Patients were excluded from individual analyses if they could not produce saliva or urine or answer questions. Primary outcomes were rates of positive BAC, UDS and self-reported risky alcohol and drug use patterns. RESULTS We screened 5264 trauma patients and enrolled 418, in whom 190 had a BAC, 364 had a UDS, and 410 had a complete ASSIST. 15 of 190 patients (7.9%) had a positive BAC, and 67/361 (18.7%) had a positive UDS for at least one drug. ASSIST scores showed 75/410 (18.3%) patients were at moderate or high risk for alcohol use disorder. Few were at risk for disordered use of other non-tobacco substances. DISCUSSION In our population of RTC drivers, positive BAC and UDS tests were rare but many patients were at risk for an alcohol use disorder. Ideal screening for substance use in Tanzanian trauma populations may involve a combination of objective testing and a verbal screening tool.

Abstract
BACKGROUND Estimating population prevalence and incidence of prior SARS-CoV-2 infection is essential to formulate public health recommendations concerning the COVID-19 pandemic. However, interpreting estimates based on sero-surveillance requires an understanding of the duration of elevated antibodies following SARS-CoV-2 infection, especially in the large number of people with pauci-symptomatic or asymptomatic disease. METHODS We examined > 30,000 serology assays for SARS-CoV-2 specific IgG and IgM assays acquired longitudinally in 11,468 adults between April and November 2020 in the COVID-19 Community Research Partnership. RESULTS Among participants with serologic evidence for infection but few or no symptoms or clinical disease, roughly 50% sero-reverted in 30 days of their initial positive test. Sero-reversion occurred more quickly for IgM than IgG and for antibodies targeting nucleocapsid protein compared with spike proteins, but was not associated with age, sex, race/ethnicity, or healthcare worker status. CONCLUSIONS The short duration of antibody response suggests that the true population prevalence of prior SARS-CoV-2 infection may be significantly higher than presumed based on earlier sero-surveillance studies. The impact of the large number of minimally symptomatic COVID-19 cases with only a brief antibody response on population immunity remains to be determined.

Abstract
BACKGROUND The objective was to test if low-risk emergency department patients with vitamin K antagonist (venous thromboembolism [VTE]; including venous thrombosis and pulmonary embolism [PE]) can be safely and effectively treated at home with direct acting oral (monotherapy) anticoagulation in a large-scale, real-world pragmatic effectiveness trial. METHODS This was a single-arm trial, conducted from 2016 to 2019 in accordance with the Standards for Reporting Implementation Studies guideline in 33 emergency departments in the United States. Participants had newly diagnosed VTE with low risk of death based upon either the modified Hestia criteria, or physician judgment plus the simplified PE severity index score of zero, together with nonhigh bleeding risk were eligible. Patients had to be discharged within 24 hours of triage and treated with either apixaban or rivaroxaban. Effectiveness was defined by the primary efficacy and safety outcomes, image-proven recurrent VTE and bleeding requiring hospitalization >24 hours, respectively, with an upper limit of the 95% CI for the 30-day frequency of VTE recurrence below 2.0% for both outcomes. RESULTS We enrolled 1421 patients with complete outcomes data, including 903 with venous thrombosis and 518 with PE. The recurrent VTE requiring hospitalization occurred in 14/1421 (1.0% [95% CI, 0.5%-1.7%]), and bleeding requiring hospitalization occurred in 12/1421 (0.8% [0.4%-1.5%). The rate of severe bleeding using International Society for Thrombosis and Haemostasis criteria was 2/1421 (0.1% [0%-0.5%]). No patient died, and serious adverse events occurred in 2.5% of venous thrombosis patients and 2.3% of patients with PE. Medication nonadherence was reported by patients in 8.0% (6.6%-9.5%) and was associated with a risk ratio of 6.0 (2.3-15.2) for VTE recurrence. Among all patients diagnosed with VTE in the emergency department during the period of study, 18% of venous thrombosis patients and 10% of patients with PE were enrolled. CONCLUSIONS Monotherapy treatment of low-risk patients with venous thrombosis or PE in the emergency department setting produced a low rate of bleeding and VTE recurrence, but may be underused. Patients with venous thrombosis and PE should undergo risk-stratification before home treatment. Improved patient adherence may reduce rate of recurrent VTE.

Abstract
OBJECTIVE Lack of empathic communication between providers and patients may contribute to low value diagnostic testing in emergency care. Accordingly, we measured the perception of physician empathy and trust in patients undergoing low-value computed tomography (CT) in the emergency department (ED). METHODS Multicenter study of ED patients undergoing CT scanning, acknowledged by ordering physicians as unlikely to show an emergent condition. Near the end of their visit, patients completed the Jefferson Scale of Patient Perception of Physician Empathy (JSPPPE), Trust in Physicians Survey (TIPS), and the Group Based Medical Mistrust Scale (GBMMS). We stratified results by patient demographics including gender, race, and education. RESULTS We enrolled 305 participants across 9 sites with diverse geographic, racial, and ethnic representation. The median scores (interquartile ranges) for the JSPPPE, TIPS, and GBMMS for all patients were 29 (24-33.5), 55 (47-62), and 18 (12-29). Compared with white patients, nonwhite patients had similar JSPPPE and TIPS scores but had higher (worse) GBMMS scores. Females had significantly lower JSPPPE and TIPS scores than males, and scores were lower (worse) in females with college degrees. Patients in the lowest tier of educational status had the highest (better) JSPPPE and TIPS scores. Scores were invariant with physician characteristics. CONCLUSION Among patients undergoing low-value CT scanning in the ED, the degree of patient perception of physician empathy and trust varied based on the patients' level of education and gender. Given this variation, an intervention to increase patient perception of physician empathy should contain individualized strategies to address these subgroups, rather than a one-size-fits-all approach.

Abstract
Introduction Basilar artery occlusion (BAO) may be clinically occult due to variable and non-specific symptomatology. We evaluated the qualitative and quantitative determination of a hyperdense basilar artery (HDBA) on non-contrast computed tomography (NCCT) brain for the diagnosis of BAO. Methods We conducted a case control study of patients with confirmed acute BAO vs a control group of suspected acute stroke patients without BAO. Two EM attending physicians, one third-year EM resident, and one medical student performed qualitative and quantitative assessments for the presence of a HDBA on axial NCCT images. Our primary outcome measures were sensitivity and specificity for BAO. Our secondary outcomes were inter-rater and intra-rater reliability of the qualitative and quantitative assessments. Results We included 60 BAO and 65 control patients in our analysis. Qualitative assessment of the hyperdense basilar artery sign was poorly sensitive (54%–72%) and specific (55%–89%). Quantitative measurement improved the specificity of hyperdense basilar artery assessment for diagnosing BAO, with a threshold of 61.0–63.8 Hounsfield units demonstrating relatively high specificity of 85%–94%. There was moderate inter-rater agreement for the qualitative assessment of HDBA (Fleiss’ kappa statistic 0.508, 95% confidence interval: 0.435–0.581). Agreement improved for quantitative assessments, but still fell in the moderate range (Shrout-Fleiss intraclass correlation coefficient: 0.635). Intra-rater reliability for the quantitative assessments of the two attending physician reviewers demonstrated substantial consistency. Conclusion Our results highlight the importance of carefully examining basilar artery density when interpreting the NCCT of patients with altered consciousness or other signs and symptoms concerning for an acute basilar artery occlusion. If the Hounsfield unit density of the basilar artery exceeds 61 Hounsfield units, BAO should be highly suspected.

Abstract
BACKGROUND Wearable sensors have allowed researchers to instrument tests of gait-related mobility, including the widely used timed 'up-and-go' test (TUG). Currently, there is a lack of instrumented test data on whether children with moderate to severe traumatic brain injury (TBI) perform differently on the TUG compared to typically developed (TD) controls during a cognitive-motor task. RESEARCH QUESTION The aim was to explore the effects of a cognitive-motor task on TUG subcomponents among children with TBI compared to TD children. METHODS This observational cross-sectional study included 12 children with moderate to severe TBI (6 males and 6 females, age 10.5 ± 1.5 years of age) and 10 age and sex-matched TD controls (5 males and 5 females, 10.4 ± 1.3 years of age). Each participant completed 6 trials of the TUG wearing a single inertial measurement unit sensor at a self-selected walking pace while listening to an array of 10 randomly presented single digits during each TUG trial. RESULTS Total time to complete the TUG was not significantly different between groups. The cognitive-motor task led to significantly lower mean turn and peak turn angular velocity values during the turn-around-the-cone and turn-before-sitting TUG subcomponents in children with TBI compared to the TD controls (p ≤ 0.05). Additionally, the cognitive-motor task led to significantly lower values for maximum torso flexion to extension angle, peak flexion and extension angular velocity and peak vertical acceleration for the sit-to-stand subcomponent (p < 0.05). Peak flexion angular velocity during the stand-to-sit subcomponent was lower for the TBI group compared to the children with TD (p < 0.05). SIGNIFICANCE The study provides new insights into the performance of complex gait-related mobility tasks in the context of an instrumented TUG among children with moderate to severe TBI. Our results highlight the potential benefits of outfitting pediatric inpatients with an IMU while completing the TUG.

Abstract
BackgroundThe specialty of emergency medicine (EM) is new in most African countries, where emergency medicine registrar (residency) programmes (EMRPs) are at different stages of evolution and little is known about the programmes. Identifying and describing these EMRPs will facilitate planning for sustainability, collaborative efforts and curriculum development for existing and future programmes. Our objective was to identify and provide an overview of existing EMRPs in Africa and their applicant requirements, faculty characteristics and plans for sustainability.MethodsWe conducted a descriptive cross-sectional survey of Africa’s EMRPs between January and December 2017, identifying programmes through an online search supplemented by discussions with African EM leaders. Leaders of all identified African EMRPs were invited to participate. Data were collected prospectively using a structured survey and are summarised with descriptive statistics.ResultsWe identified 15 programmes in 12 countries and received survey responses from 11 programmes in 10 countries. Eight of the responding EMRPs began in 2010 or later. Only 36% of the EMRPs offer a 3-year programme. Women make up an average of 33% of faculty. Only 40% of EMRPs require faculty to be EM specialists. In smaller samples that reported the relevant data, 67% (4/6) of EMRPs have EM specialists who trained in that EMRP programme making up more than half of their faculty; 57% of Africa’s 288 EMRP graduates to date are men; and an average of 39% of EMRP graduates stay on as faculty for 78% (7/9) of EMRPs.ConclusionEMRPs currently produce most of their own EM faculty. Almost equal proportions of men and women have graduated from a predominantly >3-year training programme. Graduates have a variety of opportunities in academia and private practice. Future assessments may wish to focus on the evolution of these programme’ curricula, faculty composition and graduates’ career options.

Abstract
BACKGROUND Childhood undernutrition causes significant morbidity and mortality in low- and middle-income countries (LMICs). In Tanzania, the in-hospital prevalence of undernutrition in children under five years of age is approximated to be 30% with a case fatality rate of 8.8%. In Tanzania, the burden of undernourished children under five years of age presenting to emergency departments (EDs) and their outcomes are unknown. This study describes the clinical profiles and outcomes of this population presenting to the emergency department of Muhimbili National Hospital (ED-MNH), a large, urban hospital in Dar es Salaam, Tanzania. METHODS This was a prospective descriptive study of children aged 1-59 months presenting to the ED-MNH over eight weeks in July and August 2016. Enrolment occurred through consecutive sampling. Children less than minus one standard deviation below World Health Organization mean values for Weight for Height/Length, Height for Age, or Weight for Age were recruited. Structured questionnaires were used to document primary outcomes of patient demographics and clinical presentations, and secondary outcomes of 24-h and 30-day mortality. Data was summarised using descriptive statistics and relative risks (RR). RESULTS A total of 449 children were screened, of whom 34.1% (n = 153) met criteria for undernutrition and 95.4% (n = 146) of those children were enrolled. The majority of these children, 56.2% (n = 82), were male and the median age was 19 months (IQR 10-31 months). They presented most frequently with fever 24.7% (n = 36) and cough 24.0% (n = 35). Only 6.7% (n = 9) were diagnosed with acute undernutrition by ED-MNH physicians. Mortality at 24 h and 30 days were 2.9% (n = 4) and 12.3% (n = 18) respectively. A decreased level of consciousness with Glasgow Coma Scale below fifteen on arrival to the ED and tachycardia from initial vital signs were found to be associated with a statistically significant increased risk of death in undernourished children, with mortality rates of 16.1% (n = 23), and 24.6% (n = 35), respectively. CONCLUSIONS In an urban ED of a tertiary referral hospital in Tanzania, undernutrition remains under-recognized and is associated with a high rate of in-hospital mortality.

Abstract
BACKGROUND Emergency Medicine (EM) is a rapidly developing specialty in Africa with several emergency medicine residency-training programs (EMRPs) established across the continent over the past decade. Despite rapid proliferation of the specialty, little is known about emergency care curriculum structure and content. We provide an overview of Africa's EMRPs. METHODS This was a descriptive cross-sectional survey conducted of EMRPs in Africa between January 2017 and December 2017. Data were prospectively collected using a structured survey that was developed and administered through online data capture software, REDCap (Version 7.2.2, Vanderbilt, Nashville, TN, USA). Survey questions focused on curriculum structure and design, including clinical rotations, didactics, research, and evaluation. Data are summarized with descriptive statistics. RESULTS The survey was sent to the leadership of 15 EMRPs in 12 different African countries and 11 (73%) responded. Five (46%) of the responding programs were started by local non-EM trained faculty, two (18%) were started by international partners, and the remainder by a combination of local non-EM faculty and international partners. Overall, Seven (64%) of the countries offer a 4-year EMRP. In General, 40% of curriculums are influenced the contents developed by African Federation for Emergency Medicine. All programs offer resident led-didactics, with a median of 12 h (Interquartile range 9-6 h) per month. All EMRPs have a mandatory research requirement. All EMRPs offer clinical rotations in the ED, Paediatrics, and Obstetrics and Gynaecology, while only 2 programs offer rotations in radiology and neonatal intensive care units. Only 46% of EMRPs have in-ED clinical supervision by specialist. CONCLUSION The EMRPs in Africa were started by non-EM trained local faculty alone or collaboration with international partners. The curriculum offers most exposure to ED, and less exposure in radiology and neonatal intensive care. Residents are highly involved in leading didactics and less than half of the programs have in-ED specialist supervision of patient care.

Abstract
BACKGROUND Greater than half of Emergency Medical Services (EMS) shift workers report fatigue at work and most work long duration shifts. We sought to compare the alertness level of EMS shift workers by shift duration. METHODS We used a multi-site, 14-day prospective observational cohort study design of EMS clinician shift workers at four air-medical EMS organizations. The primary outcome was behavioral alertness as measured by psychomotor vigilance tests (PVT) at the start and end of shifts. We stratified shifts by duration (< 24 h and 24 h), night versus day, and examined the impact of intra-shift napping on PVT performance. RESULTS One hundred and twelve individuals participated. The distribution of shifts <24 h and 24 h with complete data were 54% and 46%, respectively. We detected no differences in PVT performance measures stratified by shift duration (P > 0.05). Performance for selected PVT measures (lapses and false starts) was worse on night shifts compared to day shifts (P < 0.05). Performance also worsened with decreasing time between waking from a nap and the end of shift PVT assessment. CONCLUSIONS Deficits in performance in the air-medical setting may be greatest during night shifts and proximal to waking from an intra-shift nap. Future research should examine alertness and performance throughout air-medical shifts, as well as investigate the timing and duration of intra-shift naps on outcomes.

Abstract
BACKGROUND Modified systemic inflammatory response syndrome (mSIRS) criteria for the pediatric population together with the provider gestalt have the potential to predict clinical outcomes. However, this has not been studied in low-income countries. We investigated the ability of mSIRS and provider gestalt to predict mortality and morbidity among children presenting to the ED of a tertiary level hospital in Tanzania. METHODS This prospective observational study enrolled a convenience sample of children under 5 years old, presenting to the Emergency Medicine Department of Muhimbili National Hospital from September 2015 to April 2016. Trained researchers used a structured case report form to record patient demographics, clinical presentation, initial provider gestalt of severity of illness, and the mSIRS criteria. Primary outcomes were 24-h mortality and overall in-hospital mortality. Data was analyzed using simple descriptive statistics, Kruskal-Wallis, Mann-Whitney U, and chi-squared tests. RESULTS We enrolled 1350 patients, median age 17 months (interquartile range 8-32 months), and 58% were male. Provider gestalt estimates of illness severity were recorded for all patients and 1030 (76.3%) had complete data for mSIRS categorization. Provider gestalt classified 97 (7.2%) patients as healthy, 546 (40.4%) as mildly ill, 457 (33.9%) as moderately ill, and 250 (18.5%) as severely ill. Of the patients, classifiable by mSIRS, 411/1030 (39.9%) had ≥ 2 mSIRS criteria. In predicting 24-h mortality, the ≥ 2 mSIRS and gestalt "severely ill" had sensitivities of 82% and 81%, respectively, and specificity of 61% and 84%, respectively. In predicting overall in-hospital mortality, the ≥ 2 mSIRS and gestalt "severely ill" had sensitivities of 66% and 70% with a specificity of 62% and 86% respectively. CONCLUSION Both the mSIRS and provider gestalt were highly specific for predicting 24-h and overall in-hospital mortality in our patient population. The clinical utility of these assessment methods is limited by the low positive predictive value.

Abstract
BACKGROUND Alcohol and illicit drugs have been found to be major contributing factors leading to severe injuries in a variety of settings. In Tanzania, the use of these substances among injured patients has not been studied. We investigated the prevalence of positive tests for alcohol and illicit drug use among injured patients presenting to the emergency medicine department (ED) of Muhimbili National Hospital (MNH). METHODS This was a prospective cohort study of a consecutive sample of patients > 18 years of age presenting to the ED-MNH with injury related complaints in October and November 2015. A structured data sheet was used to record demographic information, mechanism of injury, clinical presentation, alcohol and illicit drug test results, and ED disposition. Alcohol levels and illicit drug use were tested by breathalyser device or swab stick alcohol test and multidrug urine panel, respectively. Patients were followed up for 24 h and 30 days using medical chart reviews and phone calls. Descriptive statistics and relative risk were used to describe the results. RESULTS We screened 1011 patients and we enrolled all 143 (14.1%) patients who met inclusion criteria. 123 (86.0%) were male, the median age was 30 years (IQR: 23-36 years). The most frequent mechanism of injury was road traffic accidents (84.6%). 67/143 (46.9%) patients tested positive for alcohol and 44/122 (36.1%) patients tested positive for drugs. 29 (26.1%) tested positive for alcohol and drugs. The most frequently detected illicit drug was marijuana in 30/122 (24.5%) injured patients. 23/53 (43.4%) patients with positive alcohol testing self-reported alcohol use. 3/25 patients with positive illicit drug tests who were able to provide self-reports, self-reported drug use. At 30-day followup, 43 (64.2%) injured patients who tested positive for alcohol had undergone major surgery, 6 (9.0%) had died, and 36 (53.7%) had not yet returned to their baseline. CONCLUSIONS The prevalence of alcohol and illicit drugs is very high in patients presenting to the ED-MNH with injury. Further studies are needed to generalise the results in Tanzania. Public health initiatives to decrease drinking and/or illicit drug use and driving should be implemented.

Abstract
BACKGROUND Emergency medicine (EM) is a new specialty in Tanzania. Little is known about how to introduce EM to health care providers (HCPs) in hospitals without EM. We determined the impact of a 2-day EM training program on the understanding, perception, and choice of EM as a career amongst HCPs at hospitals in Tanzania without EM. METHODS This was a pre- and post-training interventional study including randomly selected HCPs from four tertiary hospitals in Tanzania without EM. Understanding, perception, and desirability of EM as a career were assessed before and after a 2-day university-accredited basic EM short-course training given by EM physicians. A paper-based Likert scale (out of 5) questionnaire was used, which were analyzed by T tests, Mann-Whitney, and Kruskal-Wallis tests. RESULTS During the study period, 96 health care providers (100% capture) in the four tertiary hospitals participated in the study. The median age of participants was 34 years (IQR 28-43); 35 (36.0%) were males. Sixty (63%) were nurses, 26 (27%) doctors, and 3 (3%) were administrators. The four hospitals were equally represented. Median pre-training scores for all Likert questions were 3.49 (IQR 3.3-3.9); understanding 3.3 (IQR 3.0-3.7), perception 3.40 (IQR 3.1-3.7), and career decision-making 3.7 (IQR 3.3-4.0). Post-training scores improved with median scores of 4.6 (IQR 4.5-4.7) overall, 4.7 (IQR 4.0-4.7) for understanding, 4.6 (IQR 4.5-4.9) for perception, and 4.7 (IQR 4.3-4.8) for career decision-making (all p < 0.01). CONCLUSION A 2-day training in basic EM care had a positive impact on understanding, perception, and career decisions regarding EM amongst Tanzania HCPs that work in hospitals without EM. Follow-up to assess long-term impact, and expansion of this program, is recommended to foster EM in countries where this is a new specialty.

Abstract
Background Early and effective CPR increases both survival rate and post-arrest quality of life. In limited resource countries like Tanzania, there is scarce data describing the basic knowledge of CPR among Healthcare providers (HCP). This study aimed to determine the current level of knowledge on, and ability to perform, CPR among HCP at Muhimbili National Hospital (MNH). Methods This was a descriptive cross sectional study of a random sample of 350 HCP from all cadres and departments at MNH from October 2015 to March 2016. Each participant completed a with 25 question multiple choice and fill-in-the-blank CPR test and a practical test using a CPR manikin where the participant was videotaped for 1–2 min. Two expert observers independently viewed the videos and rated participant performance on a structured data form. The primary outcome of interest was staff member overall performance on the written and practical CPR testing. Results We enrolled 350 HCPs from all 12 MNH clinical departments. The median participant age was 35 (IQR 29–43) years, 225 (64%) were female and 138 (39%) had clinical experience of less than 5 years. Only 57 (16%) and 88 (25%) scored above 50% in written and practical tests, respectively according to local minimum passing test score and 13(4%) and 30 (9%) scored above 75% in written and practical tests, respectively according to international minimum passing test score on CPR. The 233(67%) HCP who reported prior experience performing CPR on an adult patient scored higher on testing than those without; 40% (IQR 28–54) versus 26% (IQR 16–42) respectively, but both groups had median scores <50%. Conclusion The level of CPR knowledge and skills displayed by all cadres and in all departments was poor despite the fact that most providers reported having performed CPR in the past. Since MNH is a tertiary referral hospital, it may reflect the performance of resuscitation status of other local health centers in Tanzania and other low-income countries to employ a formal system of training every HCP in CPR. Staff should be certified and assessed regularly to ensure retention of resuscitation knowledge and skills.

Abstract
Objective: The aims of this study were: 1) to determine the short-term impact of the SleepTrackTXT2 intervention on air-medical clinician fatigue during work shifts and 2) determine the longer-term impact on sleep quality over 120 days. Methods: We used a multi-site randomized controlled trial study design with a targeted enrollment of 100 (ClinicalTrials.gov NCT02783027). The intervention was behavioral (non-pharmacological) and participation was scheduled for 120 days. Participation was voluntary. All consented participants answered baseline as well as follow-up surveys. All participants answered text message queries, which assessed self-rated fatigue, sleepiness, concentration, recovery, and hours of sleep. Intervention participants received additional text messages with recommendations for behaviors that can mitigate fatigue. Intervention participants received weekly text messages that promoted sleep. Our analysis was guided by the intent-to-treat principle. For the long-term outcome of interest (sleep quality at 120 days), we used a two-sample t-test on the change in sleep quality to determine the intervention effect. Results: Eighty-three individuals were randomized and 2,828 shifts documented (median shifts per participant =37, IQR 23-49). Seventy-one percent of individuals randomized (n = 59) participated up to the 120-day study period and 52% (n = 43) completed the follow-up survey. Of the 69,530 text messages distributed, participants responded to 61,571 (88.6%). Mean sleep quality at 120 days did not differ from baseline for intervention (p > 0.05) or control group participants (p > 0.05), and did not differ between groups (p > 0.05). There was no change from baseline to 120 days in the proportion with poor sleep quality in either group. Intra-shift fatigue increased (worsened) over the course of 12-hour shifts for participants in both study arms. Fatigue at the end of 12-hour shifts was higher among control group participants than participants in the intervention group (p < 0.05). Pre-shift hours of sleep were often less than 7 hours and did not differ between the groups over time. Conclusions: The SleepTrackTXT2 behavioral intervention showed a positive short-term impact on self-rated fatigue during 12-hour shifts, but did not impact longer duration shifts or have a longer-term impact on sleep quality among air-medical EMS clinicians.

Abstract
BACKGROUND Sickle cell anaemia (SCA) is prevalent in sub-Saharan Africa, with high risk of complications requiring emergency care. There is limited information about presentation of patients with SCA to hospitals for emergency care. We describe the clinical presentation, resource utilization, and outcomes of SCA patients presenting to the emergency department (ED) at Muhimbili National Hospital (MNH) in Dar es Salaam, Tanzania. METHODS This was a prospective cohort study of consecutive patients with SCA presenting to ED between December 2014 and July 2015. Informed consent was obtained from all patients or patients' proxies prior to being enrolled in the study. A standardized case report form was used to record study information, including demographics, relevant clinical characteristics and overall patients outcomes. Categorical variables were compared with chi-square test or Fisher's exact test; continuous variables were compared with two-sample t-test or Mann-Whitney U-test. RESULTS We enrolled 752 (2.7%) people with SCA from 28,322 patients who presented to the MNH-ED. The median age was 14 years (Interquartile range [IQR]: 6-23 years), and 395 (52.8%) were female. Pain 614 (81.6%), fever 289 (38.4%) were the most frequent presenting complaint. Patients with fever, hypoxia, altered mental status and bradycardia had statistically significant relative risk of mortality of 10.4, 153, 50 and 12.1 (p < 0.0001) respectively, compared to patients with normal vitals. Overall, 656 (87.2%) patients received Complete Blood Cell counts test, of these 342 (52.1%) had severe anaemia (haemoglobin < 7 g/dl), and a 30.3 (p = 0.02) relative risk of relative risk of mortality compare to patients with higher haemoglobin. Patients who had malaria, elevated renal function test and hypoglycemia, had relative risk of mortality of 22.9, 10.4 and 45.2 (p < 0.0001) respectively, compared to patient with normal values. Most 534 (71.0%) patients were hospitalized for in patients care, and the overall morality rate was 16 (2.1%). CONCLUSIONS We described the clinical presentation, management, and outcomes of patients with SCA presenting to the largest public ED in Tanzania, as well as information on resource utilization. This information can inform development of treatment guidelines, clinical staff education, and clinical research aimed at optimizing care for SCA patients.

Abstract
BACKGROUND Hypertensive crises are clinical syndromes grouped as hypertensive urgency and emergency, which occur as complications of untreated or inadequately treated hypertension. Emergency departments across the world are the first points of contact for these patients. There is a paucity of data on patients in hypertensive crises presenting to emergency departments in Tanzania. We aimed to describe the profile and outcome of patients with hypertensive crisis presenting to the Emergency Department of Muhimbili National Hospital in Tanzania. METHODS This was a descriptive cohort study of adult patients aged 18 years and above presenting to the emergency department with hypertensive urgency or emergency over a four-month period. Trained researchers used a structured data sheet to document demographic information, clinical presentation, management and outcome. Descriptive statistics with 95% confidence intervals (CIs) are presented as well as comparisons between the groups with hypertensive urgency vs. emergency. RESULTS We screened 8002 patients and enrolled 203 (2.5%). The median age was 55 (interquartile range 45-67 years) and 51.7% were females. Overall 138 (68%) had hypertensive emergency; and 65 (32%) had hypertensive urgency, for an overall rate of 1.7% (95% CI: 1.5 to 2.0%) and 0.81% (95% CI: 0.63 to 1.0%), respectively. Altered mental status was the most common presenting symptom in hypertensive emergency [74 (53.6%)]; low Glasgow Coma Scale was the most common physical finding [61 (44.2%)]; and cerebrovascular accident was the most common final diagnosis [63 (31%)]. One hundred twelve patients with hypertensive emergency (81.2%) were admitted and three died in the emergency department, while 24 patients with hypertensive urgency (36.9%) were admitted and none died in the emergency department. In-hospital mortality rates for hypertensive emergency and urgency were 37 (26.8%) and 2 (3.1%), respectively. CONCLUSION In our cohort of adult patients with elevated blood pressure, hypertensive crisis was associated with substantial morbidity and mortality, with the most vulnerable being those with hypertensive emergency. Further research is required to determine the aetiology, pathophysiology and the most appropriate strategies for prevention and management of hypertensive crisis.

Abstract
BACKGROUND Studies have evaluated the test-re-test reliability of subcomponents of the timed up and-go test in adults by using body-worn inertial sensors. However, studies in children have not been reported in the literature. RESEARCH QUESTION To evaluate the within-session reliability of subcomponents of a newly developed electronically augmented timed 'upand-go' test (EATUG) in ambulatory children with traumatic brain injury (TBI) and children with typical development (TD). METHOD The timed up and go test was administered to twelve consecutive ambulatory children with moderate to severe TBI (6 males and 6 females, age 10.5 ± 1.5 years, range 8-13 years, during inpatient rehabilitation at 27.0 ± 11.8 days following injury) and 10 TD age and sex-matched children (5 males and 5 females, 10.4 ± 1.3 years, range 8-11 years). Participants wore a single chest-mounted inertial measurement sensor package with custom software that measured angular and acceleration velocity and torso flexion and extension angles, while they performed 6 trials of the EATUG test. Measures were derived from the overall time to complete the TUG test, angular velocity and angular displacement data for torso flexion and extension during sit-to-stand and stand-to-sit segments and both mean and peak angular velocities for two turning segments (i.e. turning around a cone and turning-before-sitting). RESULTS Within-session reliability of the subcomponents of the TUG test for children with TBI assessed by the intra-class correlation coefficient was ICC (1,1) = 0.84, (range 0.82-0.96), and for TD children ICC (1,1) = 0.73, (range 0.53-0.89). Scores on Total Time, maximum torso flexion/extension angle and peak flexion angular velocity during sit-tostand, and peak turn angular velocity for both turns around the cone and turns before sitting were lower for children with TBI than for TD children (p ≤ 0.05). SIGNIFICANCE The EATUG test is a reliable measure of physical function in children with TBI who are being discharged from inpatient rehabilitation.

Abstract
OBJECTIVE We assessed emergency department (ED) patient perceptions of how physicians can improve their language to determine patient preferences for 11 phrases to enhance physician empathy toward the goal of reducing low-value advanced imaging. METHODS Multi-center survey study of low-risk ED patients undergoing computerized tomography (CT) scanning. RESULTS We enroled 305 participants across nine sites. The statement "I have carefully considered what you told me about what brought you here today" was most frequently rated as important (88%). The statement "I have thought about the cost of your medical care to you today" was least frequently rated as important (59%). Participants preferred statements indicating physicians had considered their "vital signs and physical examination" (86%), "past medical history" (84%), and "what prior research tells me about your condition" (79%). Participants also valued statements conveying risks of testing, including potential kidney injury (78%) and radiation (77%). CONCLUSION The majority of phrases were identified as important. Participants preferred statements conveying cognitive reassurance, medical knowledge and risks of testing. PRACTICE IMPLICATIONS Our findings suggest specific phrases have the potential to enhance ED patient perceptions of physician empathy. Further research is needed to determine whether statements to convey empathy affect diagnostic testing rates.

Abstract
BACKGROUND To investigate the value of a novel simulation-based palliative care educational intervention within an emergency medicine (EM) residency curriculum. METHODS A palliative care scenario was designed and implemented in the simulation program at an urban academic emergency department (ED) with a 3-year EM residency program. EM residents attended one of eight high-fidelity simulation sessions, in groups of 5-6. A standardized participant portrayed the patient's family member. One resident from each session managed the scenario while the others observed. A 45-min debriefing session and small group discussion followed the scenario, facilitated by an EM simulation faculty member and a resident investigator. Best practices in palliative care were highlighted along with focused learner performance feedback. Participants completed an anonymous pre/post education intervention survey. RESULTS Forty of 42 EM residents (95%) participated in the study. Confidence in implementing palliative care skills and perceived importance of palliative care improved after this educational intervention. Specifically, residents 1) felt EM physicians had an important role in palliative care, 2) had increased confidence in the ability to determine patient decision-making capacity, 3) had improved confidence in initiating palliative discussions/treatment, 4) believed palliative education was important in residency, and 5) felt simulation was an effective means to learn palliative care. Differences noted between PGY1 and PGY 3 training levels in survey responses disappeared post-intervention. Residents noted being most comfortable with delivering bad news and symptom management and least comfortable with disease prognostication. Residents reported time constraints and implementation logistics in the ED as the most challenging factors for palliative care initiation. CONCLUSION Our case-based simulation intervention was associated with an increase in both the perceived importance of ED palliative care and self-reported confidence in implementing palliative care skills. Time constraints and implementation logistics were rated as the most challenging factors for palliative care initiation in the ED.

Abstract
BACKGROUND This study comprehensively reviewed the literature on the impact of shorter versus longer shifts on critical and important outcomes for Emergency Medical Services (EMS) personnel and related shift worker groups. METHODS Six databases (e.g., PubMed/MEDLINE) were searched, including one website. This search was guided by a research question developed by an expert panel a priori and registered with the PROSPERO database of systematic reviews (2016:CRD42016040099). The critical outcomes of interest were patient safety and personnel safety. The important outcomes of interest were personnel performance, acute fatigue, sleep and sleep quality, retention/turnover, long-term health, burnout/stress, and cost to system. Screeners worked independently and full-text articles were assessed for relevance. Data abstracted from the retained literature were categorized as favorable, unfavorable, mixed/inconclusive, or no impact toward the shorter shift duration. This research characterized the evidence as very low, low, moderate, or high quality according to the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology. RESULTS The searched yielded n = 21,674 records. Of the 480 full-text articles reviewed, 100 reported comparisons of outcomes of interest by shift duration. We identified 24 different shift duration comparisons, most commonly 8 hours versus 12 hours. No one study reported findings for all 9 outcomes. Two studies reported findings linked to both critical outcomes of patient and personnel safety, 34 reported findings for one of two critical outcomes, and 64 did not report findings for critical outcomes. Fifteen studies were grouped to compare shifts <24 hours versus shifts ≥24 hours. None of the findings for the critical outcomes of patient and personnel safety were categorized as unfavorable toward shorter duration shifts (<24 hours). Nine studies were favorable toward shifts <24 hours for at least one of the 7 important outcomes, while findings from one study were categorized as unfavorable. Evidence quality was low or very low. CONCLUSIONS The quality of existing evidence on the impact of shift duration on fatigue and fatigue-related risks is low or very low. Despite these limitations, this systematic review suggests that for outcomes considered critical or important to EMS personnel, shifts <24 hours in duration are more favorable than shifts ≥24 hours.

Abstract
OBJECTIVES We compared the tolerability and efficacy of intranasal subdissociative ketamine to intranasal fentanyl for analgesia of children with acute traumatic pain and investigated the feasibility of a larger noninferiority trial that could investigate the potential opioid-sparing effects of intranasal ketamine. METHODS This randomized controlled trial compared 1 mg/kg intranasal ketamine to 1.5 μg/kg intranasal fentanyl in children 4 to 17 years old with acute pain from suspected isolated extremity fractures presenting to an urban Level II pediatric trauma center from December 2015 to November 2016. Patients, parents, treating physicians, and outcome assessors were blinded to group allocation. The primary outcome, a tolerability measure, was the frequency of cumulative side effects and adverse events within 60 minutes of drug administration. The secondary outcomes included the difference in mean pain score reduction at 20 minutes, the proportion of patients achieving a clinically significant reduction in pain in 20 minutes, total dose of opioid pain medication in morphine equivalents/kg/hour (excluding study drug) required during the emergency department (ED) stay, and the feasibility of enrolling children presenting to the ED in acute pain into a randomized trial conducted under U.S. regulations. All patients were monitored until 6 hours after their last dose of study drug or until admission to the hospital ward or operating room. RESULTS Of 629 patients screened, 87 received the study drug and 82 had complete data for the primary outcome (41 patients in each group). The median (interquartile range) age was 8 (6-11) years and 62% were male. Baseline pain scores were similar among patients randomized to receive ketamine (73 ± 26) and fentanyl (69 ± 26; mean difference [95% CI] = 4 [-7 to 15]). The cumulative number of side effects was 2.2 times higher in the ketamine group, but there were no serious adverse events and no patients in either group required intervention. The most common side effects of ketamine were bad taste in the mouth (37; 90.2%), dizziness (30; 73.2%), and sleepiness (19; 46.3%). The most common side effects of fentanyl were sleepiness (15; 36.6%), bad taste in the mouth (9; 22%), and itchy nose (9; 22%). No patients experienced respiratory side effects. At 20 minutes, the mean pain scale score reduction was 44 ± 36 for ketamine and 35 ± 29 for fentanyl (mean difference = 9 [95% CI = -4 to 23]). Procedural sedation with ketamine occurred in 28 ketamine patients (65%) and 25 fentanyl patients (57%) prior to completing the study. CONCLUSIONS Intranasal ketamine was associated with more minor side effects than intranasal fentanyl. Pain relief at 20 minutes was similar between groups. Our data support the feasibility of a larger, noninferiority trial to more rigorously evaluate the safety, efficacy, and potential opioid-sparing benefits of intranasal ketamine analgesia for children with acute pain.

Abstract
Background Severe anaemia contributes significantly to mortality, especially in children under 5 years of age. Timely blood transfusion is known to improve outcomes. We investigated the magnitude of anaemia and emergency blood transfusion practices amongst children under 5 years presenting to the Emergency Department (ED) of Muhimbili National Hospital (MNH) in Tanzania. Methods This prospective observational study enrolled children under 5 years old with anaemia, over a 7-week period in August and September of 2015. Anaemia was defined as haemoglobin of <11 g/dL. Demographics, anaemia severity, indications for transfusion, receipt of blood, and door to transfusion time were abstracted from the charts using a standardized data entry form. Anaemia was categorized as severe (Hb <7 g/dL), moderate (Hb 7-9.9 g/dL) or mild (Hb 10-10.9 g/dL). Results We screened 777 children, of whom 426 (55%) had haemoglobin testing. Test results were available for 388/426 (91%), 266 (69%) of whom had anaemia. Complete data were available for 257 anaemic children, including 42% (n = 108) with severe anaemia, 40% (n = 102) with moderate anaemia and 18% (n = 47) with mild anaemia. Forty-nine percent of children with anaemia (n = 125) had indications for blood transfusion, but only 23% (29/125) were transfused in the ED. Among the non-transfused, the provider did not identify anaemia in 42% (n = 40), blood was not ordered in 28% (n = 27), and blood was ordered, but not available in 30% (n = 29). The median time to transfusion was 7.8 (interquartile range: 1.9) hours. Mortality was higher for the children with severe anemia who were not transfused as compared with those with severe anaemia who were transfused (29% vs 10%, p = 0.03). Conclusion The burden of anaemia is high among children under 5 presenting to EMD-MNH. Less than a quarter of children with indications for transfusion receive it in the EMD, the median time to transfusion is nearly 8 h, and those not transfused have nearly a 3-fold higher mortality. Future quality improvement and research efforts should focus on eliminating barriers to timely blood transfusion.

Abstract
Background Trauma contributes significantly to the burden of disease and mortality throughout the world, but particularly in developing countries. In Tanzania, there is an enormous research gap on trauma; the limited data available reflects realities in cities and areas with moderately- to highly-resourced treatment centers. Our aim was to provide a description of the injury epidemiology across all of Tanzania. Our data will serve as a basis for future larger studies. Methods This is a subgroup analysis of a cross-sectional, prospective study of the clinical epidemiology of patients presenting at all public district and regional hospitals in Tanzania. The study was conducted between May 2012 and December 2012. A team of emergency doctors used a purpose-designed data collection sheet to gather the demographic and clinical information of all patients presenting during the day-site visit to each hospital. Descriptive statistics, including means, standard deviations, medians, and ranges are reported. Results A total of 5227 patients were seen in 24-h period in 105 (100% response rate) district (or designated district) and regional hospitals in mainland Tanzania. Of these patients, 508 (9.7%) presented with trauma-related complaints. Among patients with trauma-related complaints, 286 (56.3%) were male, and the overall median age of 30 (interquartile range of 22–35) years. Road traffic crash was the most common mechanism of injury, accounting for 227 (44.7%) complaints. Open wounds and bone fractures were the two most frequent diagnoses, with a combined 300 (59%) cases. Most of the patients - 325 (64%) - were discharged, 11 (2.2%) went to operating theatres and 4 (0.8%) of patients died while receiving care at the acute intake areas. Conclusions Trauma-related complaints constitute a substantial burden among patients seeking care in acute intake areas of hospitals across Tanzania. There is a need to develop, implement and study systems that can support the improvement of trauma care and optimize outcomes of trauma patients.

Abstract
Background Poisoning is a major public health concern in sub-Saharan Africa, affecting patients of all age groups. Poisoned patients often present to the emergency department (ED) and prompt evaluation and appropriate management are imperative to ensure optimal outcomes. Unfortunately, little is known about the specific presentations of poisoned patients in East Africa. We describe the clinical and epidemiological features of patients presenting to the Muhimbili National Hospital (MNH) ED with suspected toxicological syndromes. Methods This prospective study enrolled a consecutive sample of ED patients who presented with a suspected toxicological syndrome from March 2013 to June 2013. Trained investigators completed a structured case report form (CRF) for each eligible patient, documenting the suspected poison, demographic information, the clinical presentation, and the ED outcome and disposition. The study data were analyzed and summarized with descriptive statistics. Results Of 8827 patients, who presented to ED-MNH, 106 (1.2%) met inclusion criteria, and all were enrolled. Among those enrolled, the median age was 28 years (interquartile range [IQR] 16 years), and 81 (76.4%) were male. Overall 55 (52%) were single, and 28 (26.4%) had professional jobs. 60 (56.6%) patients were referred from district hospitals, 86.8% of which were in Dar es Salaam. Only 13 (12.3%) of patients presented to the ED within 2 h of the toxic exposure. The etiology of poisoning included alcohol in 42 (50%), a mixture of different medications in 12 (14.3%), and snakebite in 6 (11.3%). Most exposures were intentional (63 [59.4%]) and were via the oral route (88 [83%]). The most common abnormal physical findings were altered mental status (66 [62.3%]) and tachypnoea (68 [64.2%]). One patient died in the ED and 98 (92.5%) required hospital admission. Conclusions Most patients presenting to the ED with a toxicological syndrome were adult males with intentional exposures. The most common toxic exposure was alcohol (ethanol) intoxication and the most common abnormal findings were altered mental status and tachypnoea. More than three-quarter of patients presented after 2 h of exposure. Almost all patients were admitted to the hospital.

Abstract
Headache is a common emergency department chief complaint. Although most are benign, emergency physicians must rapidly identify and manage the uncommon, sometimes subtle, presentation of headache from a life-threatening cause. Cerebral venous thrombosis imparts significant morbidity and mortality, and can be a challenging diagnosis. It most commonly occurs in those under 50 years of age with thrombosis of the cerebral veins/sinuses. Diagnosis is frequently delayed. The disease can present with 1 or more clinical syndromes, including intracranial hypertension with headaches, focal neurologic deficits, seizures, and encephalopathy. Diagnosis requires imaging. Treatment includes stabilization, management of complications, and anticoagulation.

Abstract
INTRODUCTION Pediatric sickle cell disease, highly prevalent in sub-Saharan Africa, carries great morbidity and mortality risk. Limited resources and monitoring make management of acute vaso-occlusive crises challenging. This study aims to evaluate the efficacy and safety of subdissociative intranasal ketamine as a cheap, readily available and easily administered adjunct to standard pain therapy. We hypothesise that subdissociative, intranasal ketamine may significantly augment current approaches to pain management in resource-limited settings in a safe and cost-effective manner. METHODS AND ANALYSIS This is a multicentred, randomised, double-blind, placebo-controlled trial enrolling children 4-16 years of age with sickle cell disease and painful vaso-occlusive pain crises. Study sites include two sub-Saharan teaching and referral hospitals with acute intake areas. All patients receive standard analgesic therapy during evaluation. Patients randomised to the treatment arm receive 1 mg/kg intranasal ketamine at onset of therapy, while placebo arm participants receive volume-matched intranasal normal saline. All participants and clinical staff are blinded to the treatment allocation. Data will be analysed on an intention-to-treat basis. Primary endpoints are changes in self-report pain scales (Faces Pain Scale-Revised) at 30, 60 and 120 minutes and rates of adverse events. Secondary endpoints include hospital length of stay, total analgesia use and quality of life assessment 2-3 weeks postintervention. ETHICS AND DISSEMINATION The research methods for this study have been approved by the Cameroon Baptist Convention Health Board Institutional Review Board (IRB2015-07), the Tanzanian National Institute for Medical Research (NIMR/HQ/R.8a/Vol. IX/2299), Muhimbili National Hospital IRB (MNH/IRB/I/2015/14) and the Tanzanian Food and Drugs Authority (TFDA0015/CTR/0015/9). Data reports will be provided to the Data and Safety Monitoring Board (DSMB) periodically throughout the study as well as all reports of adverse events. All protocol amendments will also be reviewed by the DSMB. Study results, regardless of direction or amplitude, will be submitted for publication in relevant peer-reviewed journals.

Abstract
Background Most air medical Emergency Medical Services (EMS) clinicians work extended duration shifts, and more than 50% report inadequate sleep, poor sleep quality, and/or poor recovery between shifts. The SleepTrackTXT pilot trial (ClinicalTrials.gov, NCT02063737) showed that use of mobile phone text messages could impact EMS clinician self-reported fatigue and sleepiness during long duration shifts. The purpose of the SleepTrackTXT2 trial is to leverage lessons learned from the first SleepTrackTXT study and test an enhanced intervention targeting air medical EMS clinicians. Methods/design We will conduct a multi-site randomized trial with a sample of adult EMS clinicians recruited from four air medical EMS systems located in the midwest, northeastern, and southern USA. Participants will be allocated to one of two possible arms for a 4-month (120-day) study period. The intervention arm will involve text-message assessments of sleepiness, fatigue, and difficulty concentrating at the beginning, every 4 hours during, and at the end of scheduled shifts. Participants reporting high levels of sleepiness, fatigue, or difficulty with concentration will receive one of nine randomly selected intervention messages to promote behavior change during shift work to improve alertness. Intervention participants will receive a text-message report on Friday of each week that shows their sleep debt over the previous 7 days followed by a text message to promote paying back sleep debt recovery when feasible. Participants in the control group receive text messages that only include assessments. Both arms will receive text-message assessments of perceived recovery since last shift, sleepiness, fatigue, or difficulty with concentration at noon (1200 hours) on days between scheduled shifts (off-duty days). We have two aims for this study: (1) to determine the short-term impact of the enhanced SleepTrackTXT2 intervention on air medical clinician fatigue reported in real time during and at the end of shift work, and (2) to determine the long-term impact of the SleepTrackTXT2 intervention on sleep quality and sleep health indicators including hours of sleep and recovery between shift work. Discussion The SleepTrackTXT2 trial may provide evidence of real-world effectiveness that would support widespread expansion of fatigue mitigation interventions in emergency care clinician shift workers. The trial may specifically support use of real-time assessments and interventions delivered via mobile technology such as text messaging. Trial registration ClinicalTrials.gov, NCT02783027.

Abstract
Therapeutic hypothermia has been shown to improve neurologic outcome in medical cardiac arrest patients, yet little is known about factors that delay target temperature achievement. Our primary aim was to identify factors associated with not achieving our institutional "door-to-cool" (DTC) performance goal (emergency department [ED] arrival to temperature of 34°C) of ≤4 hours. Secondary aims included whether achievement of DTC goal was associated with timing of bolus neuromuscular blockade (NMB), survival, or functional outcome. This was a retrospective cohort study of a medical cardiac arrest quality improvement (QI) database that included patients treated from November 2007 to August 2012. The database was queried for patient demographics, arrest characteristics, specific cooling techniques used, whether patients underwent emergent computed tomography imaging or cardiac catheterization, and patient outcomes. Logistic regression was used to assess the factors associated with DTC goal performance and outcomes. We enrolled 327 patients, median age 58, median return of spontaneous circulation (ROSC) time of 21 minutes (interquartile range [IQR] 14-29 minutes), and shockable initial rhythm in 61%. One hundred forty-four (44%) patients survived to hospital discharge, 133 (41%) with good functional outcome, as defined as cerebral performance category 1-2. Induction with cold IV fluids [OR 0.50 (CI: 0.29-0.85)] and NMB administration within 2 hours of ED arrival [OR 2.95 (CI: 1.17-7.43)] was associated with achieving DTC goal. Logistic regression showed that achievement of DTC goal ≤4 hours [OR 0.59 (0.32-1.09)] was not associated with good functional outcome. In our single-center cohort, initiation of cold intravenous fluids (IVF) and early NMB administration were associated with improved DTC goal performance of 4 hours. However, patients achieving DTC goals were not associated with improved outcomes.

Abstract
BACKGROUND Greater than half of Emergency Medical Services (EMS) personnel report work-related fatigue, yet there are no guidelines for the management of fatigue in EMS. A novel process has been established for evidence-based guideline (EBG) development germane to clinical EMS questions. This process has not yet been applied to operational EMS questions like fatigue risk management. The objective of this study was to develop content valid research questions in the Population, Intervention, Comparison, and Outcome (PICO) framework, and select outcomes to guide systematic reviews and development of EBGs for EMS fatigue risk management. METHODS We adopted the National Prehospital EBG Model Process and Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework for developing, implementing, and evaluating EBGs in the prehospital care setting. In accordance with steps one and two of the Model Process, we searched for existing EBGs, developed a multi-disciplinary expert panel and received external input. Panelists completed an iterative process to formulate research questions. We used the Content Validity Index (CVI) to score relevance and clarity of candidate PICO questions. The panel completed multiple rounds of question editing and used a CVI benchmark of ≥0.78 to indicate acceptable levels of clarity and relevance. Outcomes for each PICO question were rated from 1 = less important to 9 = critical. RESULTS Panelists formulated 13 candidate PICO questions, of which 6 were eliminated or merged with other questions. Panelists reached consensus on seven PICO questions (n = 1 diagnosis and n = 6 intervention). Final CVI scores of relevance ranged from 0.81 to 1.00. Final CVI scores of clarity ranged from 0.88 to 1.00. The mean number of outcomes rated as critical, important, and less important by PICO question was 0.7 (SD 0.7), 5.4 (SD 1.4), and 3.6 (SD 1.9), respectively. Patient and personnel safety were rated as critical for most PICO questions. PICO questions and outcomes were registered with PROSPERO, an international database of prospectively registered systematic reviews. CONCLUSIONS We describe formulating and refining research questions and selection of outcomes to guide systematic reviews germane to EMS fatigue risk management. We outline a protocol for applying the Model Process and GRADE framework to create evidence-based guidelines.

Abstract
INTRODUCTION Fentanyl is the most widely studied intranasal (IN) analgesic in children. IN subdissociative (INSD) ketamine may offer a safe and efficacious alternative to IN fentanyl and may decrease overall opioid use during the emergency department (ED) stay. This study examines the feasibility of a larger, multicentre clinical trial comparing the safety and efficacy of INSD ketamine to IN fentanyl and the potential role for INSD ketamine in reducing total opioid medication usage. METHODS AND ANALYSIS This double-blind, randomised controlled, pilot trial will compare INSD ketamine (1 mg/kg) to IN fentanyl (1.5 μg/kg) for analgesia in 80 children aged 4-17 years with acute pain from a suspected, single extremity fracture. The primary safety outcome for this pilot trial will be the frequency of cumulative side effects and adverse events at 60 min after drug administration. The primary efficacy outcome will be exploratory and will be the mean reduction of pain scale scores at 20 min. The study is not powered to examine efficacy. Secondary outcome measures will include the total dose of opioid pain medication in morphine equivalents/kg/hour (excluding study drug) required during the ED stay, number and reason for screen failures, time to consent, and the number and type of protocol deviations. Patients may receive up to 2 doses of study drug. ETHICS AND DISSEMINATION This study was approved by the US Food and Drug Administration, the local institutional review board and the study data safety monitoring board. This study data will be submitted for publication regardless of results and will be used to establish feasibility for a multicentre, non-inferiority trial. TRIAL REGISTRATION NUMBER NCT02521415.

Abstract
BACKGROUND Recent advances in post-cardiac arrest (CA) care including therapeutic hypothermia (TH) have improved survival and favorable neurologic outcomes for survivors of CA. Survivors often present with deep coma and lack of brainstem reflexes, which are generally associated with adverse outcomes in many disease processes. Little is known regarding the role of initial emergency department (ED) neurological examination and its potential for prognostication. OBJECTIVES The purpose of this study is to determine if components of a standardized neurologic examination are reliable prognosticators in patients recently resuscitated from CA. We hypothesize that lack of neurologic function does not reliably predict an adverse outcome and, therefore, should not be used to determine eligibility for TH. METHODS A standardized neurologic examination was performed in the ED on a prospective, convenience cohort of post-CA patients presenting to a CA resuscitation center who would undergo a comprehensive postarrest care pathway that included TH. Data such as prior sedation or active neuromuscular blockade were documented to evaluate for the presence of possible confounders. Examination findings were then compared with hospital survival and neurologic outcome at discharge as defined by the cerebral performance category (CPC) score as documented in the institutional TH registry. RESULTS Forty-nine subjects were enrolled, most of whom presented comatose with a Glasgow Coma Scale of 3 (n=41, 83.7%). Nineteen subjects (38.8%) had absence of all examination findings, of which 4 of 19 (21.1%) survived to hospital discharge. Of those with at least 1 positive examination finding, 13 of 30 subjects (43.3%) survived to hospital discharge. Subgroup analysis showed that 9 of the 19 patients with absence of brainstem reflexes did not have evidence of active neuromuscular blockade at the time of the examination; 2 of 9 (22.1%) survived to hospital discharge. Eight of these subjects in this group had not received any prior sedation; 1 of 8 (12.5%) survived to hospital discharge. Only 1 of the 17 subjects who survived was discharged with poor neurologic function with a CPC score=3, whereas all others who survived had good neurologic function, CPC score=1. CONCLUSION In this cohort of patients treated in a comprehensive postarrest care pathway that included TH, absence of neurologic function on initial ED presentation was not reliable for prognostication. Given these findings, clinicians should refrain from using the initial ED neurological examination to guide the aggressiveness of care or in counseling of family members regarding anticipated outcome.

Abstract
OBJECTIVES To describe the HIV counselling and testing practices for children presenting to an emergency department (ED) in a low-income country. SETTING The ED of a large east African national referral hospital. PARTICIPANTS This retrospective review of all paediatric (<18 years old) ED visits in 2012 enrolled patients who had an HIV test ordered and excluded those without testing. Files were available for 5540/5774 (96%) eligible patients and 1632 (30%) were tested for HIV, median age 1.3 years (IQR 9 months to 4 years), 58% <18 months old and 61% male. PRIMARY AND SECONDARY OUTCOME MEASURES The primary outcome measure was documentation of pretest and post-test counselling, or deferral of counselling, for children tested for HIV in the ED. Secondary measures included the overall rate of HIV testing, rate of counselling documented in the inpatient record when deferred in the ED, rate of counselling documented when testing was initiated by the inpatient service, rate of counselling documented by test result (positive vs negative) and the rate of referral to follow-up HIV care among patients testing positive. RESULTS Of 418 patients tested in the ED, counselling, or deferral of counselling, was documented for 70 (17%). When deferred to the ward, subsequent counselling was documented for 15/42 (36%). Counselling was documented in 33% of patients testing positive versus 1.1% patients testing negative (OR 43 (95% CI 23 to 83). Of 199 patients who tested positive and survived to hospital discharge, 76 (38%) were referred for follow-up at the HIV clinic on discharge. CONCLUSIONS Physicians documented the provision, or deferral, of counselling for <20% of children tested for HIV in the ED. Counselling was much more likely to be documented when the test result was positive. Less than 40% of those testing positive were referred for follow-up care.

Abstract
INTRODUCTION The utility of troponin as a marker for acute coronary occlusion and patient outcome after out-of-hospital cardiac arrest (OHCA) is unclear. We sought to determine whether initial or peak troponin was associated with percutaneous coronary intervention (PCI), OHCA survival or neurological outcome. METHODS Single-center retrospective-cohort study of OHCA patients treated in a comprehensive clinical pathway from November 2007 to October 2012. Troponin I levels were acquired at presentation, four and eight hours after arrest, and then per physician discretion. Cardiac catheterization was at the cardiologist's discretion. Survival and outcome were determined at hospital discharge, with cerebral performance category score 1-2 defined as a good neurological outcome. RESULTS We enrolled 277 patients; 58% had a shockable rhythm, 44% survived, 41% good neurological outcome. Of the 107 (38%) patients who underwent cardiac catheterization, 30 (28%) had PCI. Initial ED troponin (median, ng/mL) was not different in patients requiring PCI vs no PCI (0.32 vs 0.09, p=0.06), although peak troponin was higher (4.19 versus 1.57, p=0.02). Of the 85 patients who underwent cardiac catheterization without STEMI (n=85), there was no difference in those who received PCI vs no PCI in initial troponin (0.22 vs 0.06, p=0.40) or peak troponin (2.58 vs 1.43, p=0.27). Regarding outcomes, there was no difference in initial troponin in survivors versus non-survivors (0.09 vs 0.22, p=0.11), or those with a good versus poor neurological outcome (0.09 vs 0.20, p=0.11). Likewise, there was no difference in peak troponin in survivors versus non-survivors (1.64 vs 1.23, p=0.07), or in those with a good versus poor neurological outcome (1.57 vs 1.26, p=0.14). CONCLUSION In our single-center patient cohort, peak troponin, but not initial troponin, was associated with higher likelihood of PCI, while neither initial nor peak troponin were associated with survival or neurological outcome in OHCA patients.
