Blunt Head Injury in the Elderly: Analysis of the NEXUS II Injury Cohort

BACKGROUND

Changes with aging make older patients vulnerable to blunt head trauma and alter the potential for injury and the injury patterns seen among this expanding cohort. High-quality care requires a clear understanding of the factors associated with blunt head injuries in the elderly. Our objective was to develop a detailed assessment of the injury mechanisms, presentations, injury patterns, and outcomes among older blunt head trauma patients.

METHODS

We conducted a planned secondary analysis of patients aged 65 or greater who were enrolled in the National Emergency X-Radiography Utilization Study (NEXUS) Head Computed Tomography validation study. We performed a detailed assessment of the demographics, mechanisms, presentations, injuries, interventions, and outcomes among older patients.

RESULTS

We identified 3,659 patients aged 65 years or greater, among the 11,770 patients enrolled in the NEXUS validation study. Of these older patients, 325 (8.9%) sustained significant injuries, as compared with significant injuries in 442 (5.4%) of the 8,111 younger patients. Older females (1,900; 51.9%) outnumbered older males (1,753; 47.9%), and occult presentations (exhibiting no high-risk clinical criteria beyond age) occurred in 48 (14.8%; 95% confidence interval (CI) 11.1 to 19.1) patients with significant injuries. Subdural hematomas (377 discreet lesions in 299 patients) and subarachnoid hemorrhages (333 discreet instances in 256 patients) were the most frequent types of injuries occurring in our elderly population. A ground-level fall was the most frequent mechanism of injury among all patients (2,211; 69.6%), those sustaining significant injuries (180; 55.7%), and those who died of their injuries (37; 46.3%), but mortality rates were highest among patients experiencing a fall from a ladder (11.8%; 4 deaths among 34 cases [95% CI 3.3% to 27.5%]) and automobile versus pedestrian events (10.7%; 16 deaths among 149 cases [95% CI 6.3% to 16.9%]). Among older patients who required neurosurgical intervention for their injuries, only 16.4% (95% CI 11.1% to 22.9%) were able to return home, 32.1% (95% CI 25.1% to 39.8%) required extended facility care, and 41.8% (95% CI 34.2% to 49.7%) died from their injuries.

CONCLUSIONS

Older blunt head injury patients are at high risk of sustaining serious intracranial injuries even with low-risk mechanisms of injury, such as ground-level falls. Clinical evaluation is unreliable and frequently fails to identify patients with significant injuries. Outcomes, particularly after intervention, can be poor, with high rates of long-term disability and mortality.

Availability and use of institutional support programs for emergency department healthcare personnel during the COVID-19 pandemic

OBJECTIVES

The COVID-19 pandemic placed health care personnel (HCP) at risk for stress, anxiety, burnout, and post-traumatic stress disorder (PTSD). To address this, hospitals developed programs to mitigate risk. The objectives of the current study were to measure the availability and use of these programs in a cohort of academic emergency departments (EDs) in the United States early in the pandemic and identify factors associated with program use.

METHODS

Cross-sectional survey of ED HCP in 21 academic EDs in 15 states between June and September 2020. Site investigators provided data on the availability of 28 programs grouped into 9 categories. Individual support programs included: financial, workload mitigation, individual COVID-19 testing, emotional (e.g., mental health hotline), and instrumental (e.g., childcare) Clinical work support programs included: COVID-19 team communication (e.g., debriefing critical incident), patient-family communication facilitation, patient services (e.g., social work, ethics consultation), and system-level exposure reduction. Participants provided corresponding data on whether they used the programs. We used generalized linear mixed models clustered on site to measure the association between demographic and facility characteristics and program use.

RESULTS

We received 1,541 survey responses (96% response rate) from emergency physicians or advanced practice providers, nurses, and nonclinical staff. Program availability in each of the 9 categories was high (>95% of hospitals). Program use was variable, with clinical work support programs used more frequently (28-50% of eligible HCP across categories) than individual employee support programs (6-13% of eligible HCP across categories). Fifty-seven percent of respondents reported that the COVID-19 pandemic had affected their stress and anxiety, and 12% were at elevated risk for PTSD. Program use did not significantly differ for HCP who reported symptoms of anxiety and/or stress compared to those who did not.

CONCLUSIONS

Early in the pandemic, support programs were widely available to ED HCP, but program use was low. Future work will focus on identifying barriers and facilitators to use and specific programs most likely to be effective during periods of highest occupational stress.

This cross-sectional study examines COVID-19 infection status, vaccination uptake, and perceptions about the vaccine among Latinx patients presenting to the emergency department in California.

Coronavirus Disease 2019 Infections Among Emergency Health Care Personnel: Impact on Delivery of United States Emergency Medical Care, 2020

STUDY OBJECTIVE

In the early months of the coronavirus disease 2019 (COVID-19) pandemic and before vaccine availability, there were concerns that infected emergency department (ED) health care personnel could present a threat to the delivery of emergency medical care. We examined how the pandemic affected staffing levels and whether COVID-19 positive staff were potentially infectious at work in a cohort of US ED health care personnel in 2020.

METHODS

The COVID-19 Evaluation of Risks in Emergency Departments (Project COVERED) project was a multicenter prospective cohort study of US ED health care personnel conducted from May to December 2020. During surveillance, health care personnel completed weekly electronic surveys and underwent periodic serology and nasal reverse transcription polymerase chain reaction testing for SARS-CoV-2, and investigators captured weekly data on health care facility COVID-19 prevalence and health care personnel staffing. Surveys asked about symptoms, potential exposures, work attendance, personal protective equipment use, and behaviors.

RESULTS

We enrolled 1,673 health care personnel who completed 29,825 person weeks of surveillance. Eighty-nine (5.3%) health care personnel documented 90 (0.3%; 95% confidence interval [CI] 0.2% to 0.4%) person weeks of missed work related to documented or concerns for COVID-19 infection. Health care personnel experienced symptoms of COVID-19 during 1,256 (4.2%) person weeks and worked at least one shift whereas symptomatic during 1,042 (83.0%) of these periods. Seventy-five (4.5%) participants tested positive for SARS-CoV-2 during the surveillance period, including 43 (57.3%) who indicated they never experienced symptoms; 74 (98.7%; 95% CI 90.7% to 99.9%) infected health care personnel worked at least one shift during the initial period of infection, and 71 (94.7%) continued working until laboratory confirmation of their infection. Physician staffing was not associated with the facility or community COVID-19 levels within any time frame studied (Kendall tau's 0.02, 0.056, and 0.081 for no shift, one-week time shift, and 2-week time shift, respectively).

CONCLUSIONS

During the first wave of the pandemic, COVID-19 infections in ED health care personnel were infrequent, and the time lost from the workforce was minimal. Health care personnel frequently reported for work while infected with SARS-CoV-2 before laboratory confirmation. The ED staffing levels were poorly correlated with facility and community COVID-19 burden.

Trends in Presumed Drug Overdose Out-Of-Hospital Cardiac Arrests in San Francisco, 2015-2023

INTRODUCTION

Estimates of the prevalence of drug-related out of hospital cardiac arrest (OHCA) vary, ranging from 1.8 - 10.0% of medical OHCA. However, studies conducted prior to the recent wave of fentanyl deaths likely underestimate the current prevalence of drug-related OHCA. We evaluated recent trends in drug-related OHCA, hypothesizing that the proportion of presumed drug-related OHCA treated by emergency medical services (EMS) has increased since 2015.

METHODS

We conducted a retrospective analysis of OHCA patients treated by EMS providers in San Francisco, California between 2015 - 2023. Participants included OHCA cases in which resuscitation was attempted by EMS. The study exposure was the year of arrest. Our primary outcome was the occurrence of drug-related OHCA, defined as the EMS impression of OHCA caused by a presumed or known overdose of medication(s) or drug(s).

RESULTS

From 2015 to 2023, 5044 OHCA resuscitations attended by EMS (average 561 per year) met inclusion criteria. The median age was 65 (IQR 50-79); 3508 (69.6%) were male. The EMS impression of arrest etiology was drug-related in 446/5044 (8.8%) of OHCA. The prevalence of presumed drug-related OHCA increased significantly each year from 1% in 2015 to 17.6% in 2023 (p-value for trend = 0.0001). After adjustment, presumed drug-related OHCA increased by 30% each year from 2015-2023.

CONCLUSION

Drug-related OHCA is an increasingly common etiology of OHCA. In 2023, one in six OHCA was presumed to be drug related. Among participants less than 60 years old, one in three OHCA was presumed to be drug related.

Ethnic and racial differences in self-reported symptoms, health status, activity level, and missed work at 3 and 6 months following SARS-CoV-2 infection

Introduction

Data on ethnic and racial differences in symptoms and health-related impacts following SARS-CoV-2 infection are limited. We aimed to estimate the ethnic and racial differences in symptoms and health-related impacts 3 and 6 months after the first SARS-CoV-2 infection.

Methods

Participants included adults with SARS-CoV-2 infection enrolled in a prospective multicenter US study between 12/11/2020 and 7/4/2022 as the primary cohort of interest, as well as a SARS-CoV-2-negative cohort to account for non-SARS-CoV-2-infection impacts, who completed enrollment and 3-month surveys (N = 3,161; 2,402 SARS-CoV-2-positive, 759 SARS-CoV-2-negative). Marginal odds ratios were estimated using GEE logistic regression for individual symptoms, health status, activity level, and missed work 3 and 6 months after COVID-19 illness, comparing each ethnicity or race to the referent group (non-Hispanic or white), adjusting for demographic factors, social determinants of health, substance use, pre-existing health conditions, SARS-CoV-2 infection status, COVID-19 vaccination status, and survey time point, with interactions between ethnicity or race and time point, ethnicity or race and SARS-CoV-2 infection status, and SARS-CoV-2 infection status and time point.

Results

Following SARS-CoV-2 infection, the majority of symptoms were similar over time between ethnic and racial groups. At 3 months, Hispanic participants were more likely than non-Hispanic participants to report fair/poor health (OR: 1.94; 95%CI: 1.36-2.78) and reduced activity (somewhat less, OR: 1.47; 95%CI: 1.06-2.02; much less, OR: 2.23; 95%CI: 1.38-3.61). At 6 months, differences by ethnicity were not present. At 3 months, Other/Multiple race participants were more likely than white participants to report fair/poor health (OR: 1.90; 95% CI: 1.25-2.88), reduced activity (somewhat less, OR: 1.72; 95%CI: 1.21-2.46; much less, OR: 2.08; 95%CI: 1.18-3.65). At 6 months, Asian participants were more likely than white participants to report fair/poor health (OR: 1.88; 95%CI: 1.13-3.12); Black participants reported more missed work (OR, 2.83; 95%CI: 1.60-5.00); and Other/Multiple race participants reported more fair/poor health (OR: 1.83; 95%CI: 1.10-3.05), reduced activity (somewhat less, OR: 1.60; 95%CI: 1.02-2.51; much less, OR: 2.49; 95%CI: 1.40-4.44), and more missed work (OR: 2.25; 95%CI: 1.27-3.98).

Discussion

Awareness of ethnic and racial differences in outcomes following SARS-CoV-2 infection may inform clinical and public health efforts to advance health equity in long-term outcomes.

Impact of a hypothetical COVID-19 vaccine mandate on parental likelihood to vaccinate children: Exploring school-related concerns and vaccination decision-making

OBJECTIVE

We assessed the impact of a hypothetical school-entry COVID-19 vaccine mandate on parental likelihood to vaccinate their child.

METHODS

We collected demographics, COVID-19-related school concerns, and parental likelihood to vaccinate their child from parents of patients aged 3-16 years seen across nine pediatric Emergency Departments from 06/07/2021 to 08/13/2021. Wilcoxon signed-rank test compared pre- and post-mandate vaccination likelihood. Multivariate linear and logistic regression analyses explored associations between parental concerns with baseline and change in vaccination likelihood, respectively.

RESULTS

Vaccination likelihood increased from 43% to 50% with a hypothetical vaccine mandate (Z = -6.69, p < 0.001), although most parents (63%) had no change, while 26% increased and 11% decreased their vaccination likelihood. Parent concerns about their child contracting COVID-19 was associated with greater baseline vaccination likelihood. No single school-related concern explained the increased vaccination likelihood with a mandate.

CONCLUSION

Parental school-related concerns did not drive changes in likelihood to vaccinate with a mandate.

The Impact of the COVID-19 Shelter-in-Place Order on Traumatic Brain Injuries in San Francisco, California

BACKGROUND

In response to the COVID-19 pandemic, San Francisco, California issued a shelter-in-place (SIP) order in March 2020, during which emergency physicians noted a drop in trauma cases, as well as a change in traditional mechanisms of trauma.

OBJECTIVES

Our objective was to determine the epidemiology of traumatic brain injury (TBI) pre- and post-COVID-19 SIP.

METHODS

We reviewed the electronic medical record of the only trauma center in the city of San Francisco, to determine the number of and characteristics of patients with a diagnosis of head injury presenting to the emergency department between December 16, 2019 and June 16, 2020. Using chi-squared and Fisher's exact tests when appropriate, we compared pre- and post- COVID-19 lockdown epidemiology.

RESULTS

There were 1246 TBI-related visits during the 6-month study period. Bi-weekly TBI cases decreased by 36.64% 2 weeks after the COVID-19 SIP and then increased to near baseline levels by June 2020. TBI patients during SIP were older (mean age: 53.3 years pre-SIP vs. 58.2 post-SIP; p < 0.001), more likely to be male (odds ratio 1.43, 95% confidence interval 1.14-1.81), and less likely to be 17 or younger (8.9% vs. 0.5%, pre- to post-SIP respectively, p = 0.003). Patients were less likely to be Hispanic (27.2% vs. 21.7% pre- to post-SIP, respectively, p = 0.029). The proportion of TBI visits attributable to cycling accidents increased (14.1% to 52.7%, p < 0.001), whereas those attributable to pedestrians involved in road traffic accidents decreased (37.2% to 12.7%, p = 0.003).

CONCLUSIONS

Understanding the changing epidemiology of TBI during the COVID-19 pandemic can aid in immediate and future disaster resource planning.

COVID-19 Booster Vaccine Hesitancy in the Emergency Department

STUDY OBJECTIVE

Little is known about COVID-19 booster vaccine hesitancy. We sought to determine the uptake of booster vaccines, as well as the prevalence of and reasons for booster hesitancy in emergency department (ED) patients.

METHODS

We performed a cross-sectional survey study of adult patients at 5 safety-net hospital EDs in 4 US cities from mid-January to mid-July 2022. Participants were fluent in English or Spanish and had received at least one COVID-19 vaccine. We assessed the following parameters: (1) the prevalence of nonboosted status and reasons for not getting a booster; (2) the prevalence of booster vaccine hesitancy and reasons for hesitancy; and (3) the association of hesitancy with demographic variables.

RESULTS

Of 802 participants, 373 (47%) were women, 478 (60%) were non-White, 182 (23%) lacked primary care, 110 (14%) primarily spoke Spanish, and 370 (46%) were publicly insured. Of the 771 participants who completed their primary series, 316 (41%) had not received a booster vaccine; the primary reason for nonreceipt was lack of opportunity (38%). Of the nonboosted participants, 179 (57%) expressed hesitancy, citing need for more information (25%), concerns about side effects (24%), and the belief that a booster was unnecessary after the initial series (20%). In the multivariable analysis, Asian participants were less likely to be booster hesitant than White participants (adjusted odds ratio [aOR] 0.21, 95% confidence interval [CI] 0.05 to 0.93), non-English-speaking participants were more likely to be booster hesitant than English-speaking participants (aOR 2.35, 95% CI 1.49 to 3.71), and Republican participants were more likely to be booster hesitant than Democrat participants (aOR 6.07, 95% CI 4.21 to 8.75).

CONCLUSION

Of almost half of this urban ED population who had not received a COVID-19 booster vaccine, more than one third stated that lack of opportunity to receive one was the primary reason. Furthermore, more than half of the nonboosted participants were booster hesitant, with many expressing concerns or a desire for more information that may be addressed with booster vaccine education.

Efficacy of emergency department calcium administration in cardiac arrest: A 9-year retrospective evaluation

BACKGROUND

The efficacy of empiric calcium for patients with undifferentiated cardiac arrest has come under increased scrutiny, including a randomized controlled trial that was stopped early due to a trend towards harm with calcium administration. However, small sample sizes and non-significant findings have hindered precise effect estimates. In this analysis we evaluate the association of calcium administration with survival in a large retrospective cohort of patients with cardiac arrest treated in the emergency department (ED).

METHODS

We conducted a retrospective review of medical records from two academic hospitals (one quaternary care center, one county trauma center) in San Francisco between 2011 and 2019. Inclusion criteria were patients aged greater than or equal to 18 years old who received treatment for cardiac arrest during their ED course. Our primary exposure was the administration of calcium while in the ED and the main outcome was survival to hospital admission. The association between calcium and survival to admission was estimated using a multivariable log-binomial regression, and also with two propensity score models.

RESULTS

We examined 781 patients with cardiac arrest treated in San Francisco EDs between 2011 and 2019 and found that calcium administration was associated with decreased survival to hospital admission (RR 0.74; 95% CI 0.66-0.82). These findings remained significant after adjustment for patient age, sex, whether the cardiac arrest was witnessed, and including an interaction term for shockable cardiac rhythms (RR 0.60; 95% CI 0.50-0.72) and non-shockable cardiac rhythms (RR 0.87; 95% CI 0.76-0.99). Risk ratios for the association between calcium and survival to hospital admission were also similar between two propensity score-based models: nearest neighbor propensity matching model (RR 0.79; 95% CI 0.68-0.89) and inverse propensity weighted regression adjustment model (RR 0.75; 95% CI 0.67-0.84).

CONCLUSIONS

Calcium administration as part of ED-directed treatment for cardiac arrest was associated with lower survival to hospital admission. Given the lack of statistically significant outcomes from smaller, more methodologically robust evaluations on this topic, we believe these findings have an important role to serve in confirming previous results and allowing for more precise effect estimates. Our data adds to the growing body evidence against the empiric use of calcium in cardiac arrest.

Accuracy of physician gestalt in prediction of significant abdominal and pelvic injury in adult blunt trauma patients

OBJECTIVE

Focusing on potential missed injury rates and sensitivity of low-risk of injury predictions, we sought to evaluate the accuracy of physician gestalt in predicting clinically significant injury (CSI) in the abdomen and pelvis among blunt trauma patients presenting to the emergency department (ED).

METHODS

We collected gestalt data on physicians caring for adult blunt trauma patients who received abdominal/pelvic computed tomography (CT) at three Level I and one Level II trauma centers. The primary outcome of CSI was defined as injury on abdominal/pelvic CT requiring hospitalization or intervention. Physicians evaluating trauma patients estimated the likelihood of CSI prior to abdominal/pelvic CT review (response choices: <2%, 2%-10%, 11%-20%, 21%-40%, >40%). We evaluated potential missed injury rates (prevalence of CSI) and sensitivity for prediction categories, as well as calibration and area under the receiver operating characteristic (AUROC) curve for overall physician gestalt.

RESULTS

Of 2030 patients, 402 (20%) had an injury on abdominal/pelvic CT and 270 (13%) had CSI. The <2% risk of CSI gestalt cutoff had a potential missed injury rate of 5.6% and a sensitivity of 95.2% (95% confidence interval [CI] 91.7%-97.3%). The 0%-10% cutoff of CSI gestalt had a potential missed injury rate of 6.3% (95% CI, 5.0%-7.9%) and a sensitivity of 75.2% (95% CI 69.5%-80.1%). With an overall AUROC of 0.699 (95% CI 0.679-0.719), physician gestalt was moderately accurate and calibrated for the midranges of predicted risk but poorly calibrated at the extremes.

CONCLUSIONS

Physician gestalt for the prediction of adult abdominal and pelvic CSI is moderately accurate and calibrated. However, the potential missed CSI rate and low sensitivity of the low perceived risk of injury cutoffs indicate that gestalt by itself is insufficient to direct selective abdominal/pelvic CT use in adult blunt trauma patient evaluation.

Prevalence of Symptoms ≤12 Months After Acute Illness, by COVID-19 Testing Status Among Adults - United States, December 2020-March 2023

To further the understanding of post-COVID conditions, and provide a more nuanced description of symptom progression, resolution, emergence, and reemergence after SARS-CoV-2 infection or COVID-like illness, analysts examined data from the Innovative Support for Patients with SARS-CoV-2 Infections Registry (INSPIRE), a prospective multicenter cohort study. This report includes analysis of data on self-reported symptoms collected from 1,296 adults with COVID-like illness who were tested for SARS-CoV-2 using a Food and Drug Administration-approved polymerase chain reaction or antigen test at the time of enrollment and reported symptoms at 3-month intervals for 12 months. Prevalence of any symptom decreased substantially between baseline and the 3-month follow-up, from 98.4% to 48.2% for persons who received a positive SARS-CoV-2 test results (COVID test-positive participants) and from 88.2% to 36.6% for persons who received negative SARS-CoV-2 test results (COVID test-negative participants). Persistent symptoms decreased through 12 months; no difference between the groups was observed at 12 months (prevalence among COVID test-positive and COVID test-negative participants = 18.3% and 16.1%, respectively; p>0.05). Both groups reported symptoms that emerged or reemerged at 6, 9, and 12 months. Thus, these symptoms are not unique to COVID-19 or to post-COVID conditions. Awareness that symptoms might persist for up to 12 months, and that many symptoms might emerge or reemerge in the year after COVID-like illness, can assist health care providers in understanding the clinical signs and symptoms associated with post-COVID-like conditions.

Association Between SARS-CoV-2 Variants and Frequency of Acute Symptoms: Analysis of a Multi-institutional Prospective Cohort Study-December 20, 2020-June 20, 2022

Background

While prior work examining severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern focused on hospitalization and death, less is known about differences in clinical presentation. We compared the prevalence of acute symptoms across pre-Delta, Delta, and Omicron.

Methods

We conducted an analysis of the Innovative Support for Patients with SARS-CoV-2 Infections Registry (INSPIRE), a cohort study enrolling symptomatic SARS-CoV-2-positive participants. We determined the association between the pre-Delta, Delta, and Omicron time periods and the prevalence of 21 coronavirus disease 2019 (COVID-19) acute symptoms.

Results

We enrolled 4113 participants from December 2020 to June 2022. Pre-Delta vs Delta vs Omicron participants had increasing sore throat (40.9%, 54.6%, 70.6%; P < .001), cough (50.9%, 63.3%, 66.7%; P < .001), and runny noses (48.9%, 71.3%, 72.9%; P < .001). We observed reductions during Omicron in chest pain (31.1%, 24.2%, 20.9%; P < .001), shortness of breath (42.7%, 29.5%, 27.5%; P < .001), loss of taste (47.1%, 61.8%, 19.2%; P < .001), and loss of smell (47.5%, 55.6%, 20.0%; P < .001). After adjustment, those infected during Omicron had significantly higher odds of sore throat vs pre-Delta (odds ratio [OR], 2.76; 95% CI, 2.26-3.35) and Delta (OR, 1.96; 95% CI, 1.69-2.28).

Conclusions

Participants infected during Omicron were more likely to report symptoms of common respiratory viruses, such as sore throat, and less likely to report loss of smell and taste.

Severe Fatigue and Persistent Symptoms at 3 Months Following Severe Acute Respiratory Syndrome Coronavirus 2 Infections During the Pre-Delta, Delta, and Omicron Time Periods: A Multicenter Prospective Cohort Study

BACKGROUND

Most research on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants focuses on initial symptomatology with limited longer-term data. We characterized prevalences of prolonged symptoms 3 months post-SARS-CoV-2 infection across 3 variant time-periods (pre-Delta, Delta, and Omicron).

METHODS

This multicenter prospective cohort study of adults with acute illness tested for SARS-CoV-2 compared fatigue severity, fatigue symptoms, organ system-based symptoms, and ≥3 symptoms across variants among participants with a positive ("COVID-positive") or negative SARS-CoV-2 test ("COVID-negative") at 3 months after SARS-CoV-2 testing. Variant periods were defined by dates with ≥50% dominant strain. We performed multivariable logistic regression modeling to estimate independent effects of variants adjusting for sociodemographics, baseline health, and vaccine status.

RESULTS

The study included 2402 COVID-positive and 821 COVID-negative participants. Among COVID-positives, 463 (19.3%) were pre-Delta, 1198 (49.9%) Delta, and 741 (30.8%) Omicron. The pre-Delta COVID-positive cohort exhibited more prolonged severe fatigue (16.7% vs 11.5% vs 12.3%; P = .017) and presence of ≥3 prolonged symptoms (28.4% vs 21.7% vs 16.0%; P < .001) compared with the Delta and Omicron cohorts. No differences were seen in the COVID-negatives across time-periods. In multivariable models adjusted for vaccination, severe fatigue and odds of having ≥3 symptoms were no longer significant across variants.

CONCLUSIONS

Prolonged symptoms following SARS-CoV-2 infection were more common among participants infected during pre-Delta than with Delta and Omicron; however, these differences were no longer significant after adjusting for vaccination status, suggesting a beneficial effect of vaccination on risk of long-term symptoms.

Effect of the Extended Focused Assessment With Sonography for Trauma on the Screening Performance of the National Emergency X-Radiography Utilization Study Chest Decision Instrument

STUDY OBJECTIVE

Developed to decrease unnecessary thoracic computed tomography use in adult blunt trauma patients, the National Emergency X-Radiography Utilization Study (NEXUS) Chest clinical decision instrument does not include the extended Focused Assessment with Sonography in Trauma (eFAST). We assessed whether eFAST improves the NEXUS Chest clinical decision instrument's diagnostic performance and may replace the chest radiograph (CXR) as a predictor variable.

METHODS

We performed a secondary analysis of prospective data from 8 Level I trauma centers from 2011-2014. We compared performance of modified clinical decision instruments that (1) added eFAST as a predictor (eFAST-added clinical decision instrument), and (2) replaced CXR with eFAST (eFAST-replaced clinical decision instrument), in screening for blunt thoracic injuries.

RESULTS

One thousand nine hundred fifty-seven patients had documented computed tomography, CXR, clinical NEXUS criteria, and adequate eFAST; 624 (31.9%) patients had blunt thoracic injuries, and 126 (6.4%) had major injuries. Compared to the NEXUS Chest clinical decision instrument, the eFAST-added clinical decision instrument demonstrated unchanged screening performance for major injury (sensitivity 0.98 [0.94 to 1.00], specificity 0.28 [0.26 to 0.30]) or any injury (sensitivity 0.97 [0.95 to 0.98], specificity 0.21 [0.19 to 0.23]). The eFAST-replaced clinical decision instrument demonstrated unchanged sensitivity for major injury (sensitivity 0.93 [0.87 to 0.97], specificity 0.31 [0.29 to 0.34]) and decreased sensitivity for any injury (0.93 [0.91 to 0.951] versus 0.97 [0.953 to 0.98]).

CONCLUSION

In our secondary analysis, adding eFAST as a predictor variable did not improve the diagnostic screening performance of the original NEXUS Chest clinical decision instrument; eFAST cannot replace the CXR criterion of the NEXUS Chest clinical decision instrument.

Physical Examination Sensitivity for Skull Fracture in Pediatric Patients With Blunt Head Trauma: A Secondary Analysis of the National Emergency X-Radiography Utilization Study II Head Computed Tomography Validation Study

STUDY OBJECTIVE

We evaluated the emergency department (ED) providers' ability to detect skull fractures in pediatric patients presenting with blunt head trauma.

METHODS

This was a secondary analysis of the National Emergency X-Radiography Utilization Study (NEXUS) Head computed tomography (CT) validation study. Demographics and clinical characteristics were analyzed for pediatric patients. Radiologist interpretations of head CT imaging were abstracted and cataloged. Detection of skull fractures was evaluated through provider response to specific clinical decision instrument criteria (NEXUS or Canadian head CT rules) at the time of initial patient evaluation. The presence of skull fracture was determined by formal radiologist interpretation of CT imaging.

RESULTS

Between April 2006, and December 2015, 1,018 pediatric patients were enrolled. One hundred twenty-eight (12.5%) children had a notable injury reported on CT head. Skull fracture was present in most (66.4%) children with intracranial injuries. The sensitivity and specificity of provider physical examination to detect skull fractures was 18.5% (95% confidence interval 10.5% to 28.7%) and 96.6% (95.3% to 97.7%), respectively. The most common injuries associated with skull fractures were subarachnoid hemorrhage (27%) and subdural hematoma (22.3%).

CONCLUSION

Skull fracture is common in children with intracranial injury after blunt head trauma. Despite this, providers were found to have poor sensitivity for skull fractures in this population, and these injuries may be missed on initial emergency department assessment.

Effect of COVID-19 Vaccine Messaging Platforms in Emergency Departments on Vaccine Acceptance and Uptake: A Cluster Randomized Clinical Trial

IMPORTANCE

Large segments of the US population's primary health care access occurs in emergency departments (EDs). These groups have disproportionately high COVID-19 vaccine hesitancy and lower vaccine uptake.

OBJECTIVE

To determine whether provision of COVID-19 vaccine messaging platforms in EDs increases COVID-19 vaccine acceptance and uptake in unvaccinated patients.

DESIGN, SETTING, AND PARTICIPANTS

This prospective cluster randomized clinical trial was conducted at 7 hospital EDs in 4 US cities from December 6, 2021, to July 28, 2022. Noncritically ill adult patients who had not previously received COVID-19 vaccines were enrolled.

INTERVENTIONS

A 3-pronged COVID-19 vaccine messaging platform (an English- or Spanish-language 4-minute video; a 1-page informational flyer; and a brief, scripted message from an ED physician or nurse) was delivered during patient waiting times.

MAIN OUTCOMES AND MEASURES

The 2 primary outcomes were (1) COVID-19 vaccine acceptance, assessed by survey responses in the ED, and (2) receipt of a COVID-19 vaccine within 30 days, ascertained by ED confirmation of vaccination, electronic health record review, and telephone follow-up.

RESULTS

Of the 496 participants enrolled (221 during intervention weeks and 275 during control weeks), the median (IQR) age was 39 (30-54) years, 205 (41.3%) were female, 193 (38.9%) were African American, 97 (19.6%) were Latinx, and 218 (44.0%) lacked primary care physicians. More intervention group participants, compared with control participants, stated that they would accept the vaccine in the ED (57 [25.8%] vs 33 [12.0%]; adjusted difference, 11.9 [95% CI, 4.5-19.3] percentage points; number needed to treat [NNT], 8 [95% CI, 5-22]). More intervention group participants than control participants received a COVID-19 vaccine within 30 days of their ED visit (44 [20.0%] vs 24 [8.7%]; adjusted difference, 7.9 [95% CI, 1.7-14.1] percentage points; NNT, 13 [95% CI, 7-60]). The intervention group had greater outcome effect sizes than the control group in participants who lacked a primary care physician (acceptance, 38 of 101 [37.6%] vs 16 of 117 [13.7%] [P for interaction = .004]; uptake, 31 of 101 [30.7%] vs 11 of 117 [9.4%] [P for interaction = .006]), as well as in Latinx persons (acceptance, 23 of 52 [44.2%] vs 5 of 48 [10.4%] [P for interaction = .004]; uptake, 22 of 52 [42.3%] vs 4 of 48 [8.3%] [P for interaction < .001]).

CONCLUSIONS AND RELEVANCE

Results of this cluster randomized clinical trial showed that with low NNT, implementation of COVID-19 vaccine messaging platforms in EDs leads to greater vaccine acceptance and uptake in unvaccinated ED patients. Broad implementation in EDs could lead to greater COVID-19 vaccine delivery to underserved populations whose primary health care access occurs in EDs.

Perspectives of COVID-19 vaccine-hesitant emergency department patients to inform messaging platforms to promote vaccine uptake

OBJECTIVES

Efforts to promote COVID-19 vaccine acceptance must consider the critical role of the emergency department (ED) in providing health care to underserved patients. Focusing on patients who lacked primary care, we sought to elicit the perspectives of unvaccinated ED patients regarding COVID-19 vaccination concerns and potential approaches that might increase their vaccine acceptance.

METHODS

We conducted this qualitative interview study from August to November 2021 at four urban EDs in San Francisco, California; Seattle, Washington; Durham, North Carolina; and Philadelphia, Pennsylvania. We included ED patients who were ≥18 years old, fluent in English or Spanish, had not received a COVID-19 vaccine, and did not have primary care physicians or clinics. We excluded patients who were unable to complete an interview, in police custody, under suspicion of active COVID-19 illness, or presented with a psychiatric chief complaint. We enrolled until we reached thematic saturation in relevant domains. We analyzed interview transcripts with a content analysis approach focused on identifying concerns about COVID-19 vaccines and ideas regarding the promotion of vaccine acceptance and potential trusted messengers.

RESULTS

Of 65 patients enrolled, 28 (43%) identified as female, their median age was 36 years (interquartile range 29-49), and 12 (18%) interviews were conducted in Spanish. Primary concerns about COVID-19 vaccines included risk of complications, known and unknown side effects, and fear of contracting COVID-19 from vaccines. Trust played a major role for patients in deciding which sources to use for vaccine information and in engendering vaccine acceptance. Health care providers and family or friends were commonly cited as trusted messengers of information.

CONCLUSIONS

We characterized concerns about COVID-19 vaccines, uncovered themes that may promote vaccine acceptance, and identified trusted messengers-primarily health care professionals. These data may inform the development of nuanced COVID-19 vaccine messaging platforms to address COVID-19 vaccine hesitancy among underserved ED populations.

Depression, anxiety, and burnout among hospital workers during the COVID-19 pandemic: A cross-sectional study

OBJECTIVES

Healthcare personnel have faced unprecedented mental health challenges during the COVID-19 pandemic. The study objective is to assess differences in depression, anxiety, and burnout among healthcare personnel with various occupational roles and whether financial and job strain were associated with these mental health outcomes.

METHODS

We employed an anonymous survey between July and August 2020 at an urban county hospital in California, USA. We assessed depression, anxiety, and burnout using validated scales, and asked questions on financial strain and job strain. We performed logistic and linear regression analyses.

RESULTS

Nurses (aOR 1.93, 95% CIs 1.12, 3.46), social workers (aOR 2.61, 95% CIs 1.35, 5.17), service workers (aOR 2.55, 95% CIs 1.20, 5.48), and administrative workers (aOR 2.93, 95% CIs 1.57, 5.61) were more likely than physicians to screen positive for depression. The odds of screening positive for anxiety were significantly lower for ancillary workers (aOR 0.32, 95% CIs 0.13-0.72) compared with physicians. Ancillary (aB = -1.77, 95% CIs -1.88, -0.47) and laboratory and pharmacy workers (aB -0.70, 95% CI -1.34, -0.06) reported lower levels of burnout compared with physicians. Financial strain partially accounted for differences in mental health outcomes across job categories. Lack of time to complete tasks and lack of supervisory support were associated with higher odds of screening positive for depression. Less job autonomy was associated with higher odds of screening positive for anxiety and higher burnout levels.

CONCLUSIONS

We found significant disparities in mental health outcomes across occupational roles. Policies to mitigate the adverse impact of COVID-19 on health workers' mental health should include non-clinical staff and address financial support and job characteristics for all occupational roles.

Outcomes in Patients With Mild Traumatic Brain Injury Without Acute Intracranial Traumatic Injury

IMPORTANCE

Traumatic brain injury (TBI) affects millions of people in the US each year. Most patients with TBI seen in emergency departments (EDs) have a Glasgow Coma Scale (GCS) score of 15 and a head computed tomography (CT) scan showing no acute intracranial traumatic injury (negative head CT scan), yet the short-term and long-term functional outcomes of this subset of patients remain unclear.

OBJECTIVE

To describe the 2-week and 6-month recovery outcomes in a cohort of patients with mild TBI with a GCS score of 15 and a negative head CT scan.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study analyzed participants who were enrolled from January 1, 2014, to December 31, 2018, in the Transforming Research and Clinical Knowledge in Traumatic Brain Injury (TRACK-TBI) study, a prospective, observational cohort study of patients with TBI that was conducted in EDs of 18 level I trauma centers in urban areas. Of the total 2697 participants in the TRACK-TBI study, 991 had a GCS score of 15 and negative head CT scan and were eligible for inclusion in this analysis. Data were analyzed from September 1, 2021, to May 30, 2022.

MAIN OUTCOMES AND MEASURES

The primary outcome was the Glasgow Outcome Scale-Extended (GOS-E) score, which was stratified according to functional recovery (GOS-E score, 8) vs incomplete recovery (GOS-E score, <8), at 2 weeks and 6 months after the injury. The secondary outcome was severity of mild TBI-related symptoms assessed by the Rivermead Post Concussion Symptoms Questionnaire (RPQ) total score.

RESULTS

A total of 991 participants (mean [SD] age, 38.5 [15.8] years; 631 male individuals [64%]) were included. Of these participants, 751 (76%) were followed up at 2 weeks after the injury: 204 (27%) had a GOS-E score of 8 (functional recovery), and 547 (73%) had a GOS-E scores less than 8 (incomplete recovery). Of 659 participants (66%) followed up at 6 months after the injury, 287 (44%) had functional recovery and 372 (56%) had incomplete recovery. Most participants with incomplete recovery reported that they had not returned to baseline or preinjury life (88% [479 of 546]; 95% CI, 85%-90%). Mean RPQ score was 16 (95% CI, 14-18; P < .001) points lower at 2 weeks (7 vs 23) and 18 (95% CI, 16-20; P < .001) points lower at 6 months (4 vs 22) in participants with a GOS-E score of 8 compared with those with a GOS-E score less than 8.

CONCLUSIONS AND RELEVANCE

This study found that most participants with a GCS score of 15 and negative head CT scan reported incomplete recovery at 2 weeks and 6 months after their injury. The findings suggest that emergency department clinicians should recommend 2-week follow-up visits for these patients to identify those with incomplete recovery and to facilitate their rehabilitation.

Developing a decision instrument to guide abdominal-pelvic imaging of blunt trauma patients: Methodology and protocol of the NEXUS abdominal-pelvic imaging study

Although computed tomography (CT) of the abdomen and pelvis (A/P) can provide crucial information for managing blunt trauma patients, liberal and indiscriminant imaging is expensive, can delay critical interventions, and unnecessarily exposes patients to ionizing radiation. Currently no definitive recommendations exist detailing which adult blunt trauma patients should receive A/P CT imaging and which patients may safely forego CT. Considerable benefit could be realized by identifying clinical criteria that reliably classify the risk of abdominal and pelvic injuries in blunt trauma patients. Patients identified as “very low risk” by such criteria would be free of significant injury, receive no benefit from imaging and therefore could be safely spared the expense and radiation exposure associated with A/P CT. The goal of this two-phase nationwide multicenter observational study is to derive and validate the use of clinical criteria to stratify the risk of injuries to the abdomen and pelvis among adult blunt trauma patients. We estimate that nation-wide implementation of a rigorously developed decision instrument could safely reduce CT imaging of adult blunt trauma patients by more than 20%, and reduce annual radiographic charges by $180 million, while simultaneously expediting trauma care and decreasing radiation exposure with its attendant risk of radiation-induced malignancy. Prior to enrollment we convened an expert panel of trauma surgeons, radiologists and emergency medicine physicians to develop a consensus definition for clinically significant abdominal and pelvic injury. In the first derivation phase of the study, we will document the presence or absence of preselected candidate criteria, as well as the presence or absence of significant abdominal or pelvic injuries in a cohort of blunt trauma victims. Using recursive partitioning, we will examine combinations of these criteria to identify an optimal “very low risk” subset that identifies injuries with a sensitivity exceeding 98%, excludes injury with a negative predictive value (NPV) greater than 98%, and retains the highest possible specificity and potential to decrease imaging. In Phase 2 of the study we will validate the performance of a decision rule based on these criteria among a new cohort of patients to ensure that the criteria retain high sensitivity, NPV and optimal specificity. Validating the sensitivity of the decision instrument with high statistical precision requires evaluations on 317 blunt trauma patients who have significant abdominal-pelvic injuries, which will in turn require evaluations on approximately 6,340 blunt trauma patients. We will estimate potential reductions in CT imaging by counting the number of abdominal-pelvic CT scans performed on “very low risk” patients. Reductions in charges and radiation exposure will be determined by respectively summing radiographic charges and lifetime decreases in radiation morbidity and mortality for all “very low risk” cases.

PROmotion of COvid-19 VA(X)ccination in the Emergency Department-PROCOVAXED: study protocol for a cluster randomized controlled trial

Background

We conducted in-depth interviews to characterize reasons for COVID-19 vaccine hesitancy in emergency department (ED) patients and developed messaging platforms that may address their concerns. In this trial, we seek to determine whether provision of these COVID-19 vaccine messaging platforms in EDs will be associated with greater COVID-19 vaccine acceptance and uptake in unvaccinated ED patients.

Methods

This is a cluster-randomized controlled trial (RCT) evaluating our COVID-19 vaccine messaging platforms in seven hospital EDs (mix of academic, community, and safety-net EDs) in four US cities. Within each study site, we randomized 30 1-week periods to the intervention and 30 1-week periods to the control. Adult patients who have not received a COVID-19 vaccine are eligible with these exclusions: (1) major trauma, intoxication, altered mental status, or critical illness; (2) incarceration; (3) psychiatric chief complaint; and (4) suspicion of acute COVID-19 illness. Participants receive an orally administered Intake survey. During intervention weeks, participants then receive three COVID-19 vaccine messaging platforms (4-min video, one-page informational flyer and a brief, scripted face-to-face message delivered by an ED physician or nurse); patients enrolled during non-intervention weeks do not receive these platforms. Approximately, an hour after intake surveys, participants receive a Vaccine Acceptance survey during which the primary outcome of acceptance of the COVID-19 vaccine in the ED is ascertained. The other primary outcome of receipt of a COVID-19 vaccine within 32 days is ascertained by electronic health record review and phone follow-up. To determine whether provision of vaccine messaging platforms is associated with a 7% increase in vaccine acceptance and uptake, we will need to enroll 1290 patients.

Discussion

Highlighting the difficulties of trial implementation during the COVID-19 pandemic in acute care settings, our novel trial will lay the groundwork for delivery of public health interventions to vulnerable populations whose only health care access occurs in EDs.

Conclusions

Toward addressing vaccine hesitancy in vulnerable populations who seek care in EDs, our cluster-RCT will determine whether implementation of vaccine messaging platforms is associated with greater COVID-19 vaccine acceptance and uptake in unvaccinated ED patients.

Facemasks: Perceptions and use in an ED population during COVID-19

Study objective

Facemask use is associated with reduced transmission of SARS-CoV-2. Most surveys assessing perceptions and practices of mask use miss the most vulnerable racial, ethnic, and socio-economic populations. These same populations have suffered disproportionate impacts from the pandemic. The purpose of this study was to assess beliefs, access, and practices of mask wearing across 15 urban emergency department (ED) populations.

Methods

This was a secondary analysis of a cross-sectional study of ED patients from December 2020 to March 2021 at 15 geographically diverse, safety net EDs across the US. The primary outcome was frequency of mask use outside the home and around others. Other outcome measures included having enough masks and difficulty obtaining them.

Results

Of 2,575 patients approached, 2,301 (89%) agreed to participate; nine had missing data pertaining to the primary outcome, leaving 2,292 included in the final analysis. A total of 79% of respondents reported wearing masks “all of the time” and 96% reported wearing masks over half the time. Subjects with PCPs were more likely to report wearing masks over half the time compared to those without PCPs (97% vs 92%). Individuals experiencing homelessness were less likely to wear a mask over half the time compared to those who were housed (81% vs 96%).

Conclusions

Study participants reported high rates of facemask use. Respondents who did not have PCPs and those who were homeless were less likely to report wearing a mask over half the time and more likely to report barriers in obtaining masks. The ED may serve a critical role in education regarding, and provision of, masks for vulnerable populations.

Impact of Anti-Immigrant Rhetoric on Latinx Families' Perceptions of Child Safety and Health Care Access

BACKGROUND

Political rhetoric from the former U.S. president influences Latinx adults' feelings of safety and their decisions to seek care in the emergency department (ED).

OBJECTIVE

Our aim was to examine the impact of political rhetoric on feelings of safety and health care access in the pediatric population.

METHODS

This was a cross-sectional study of undocumented Latinx families (ULF), Latinx U.S. citizen families (LCF), and non-Latinx U.S. citizen families (NLF) conducted from November 2018 through February 2020 by means of interviewing a convenience sample of parents and guardians who brought their child to a pediatric clinic and two EDs in California.

RESULTS

Of 705 parents approached, 449 (63.7%) agreed to participate: 138 ULF, 150 LCF, and 158 NLF. Most ULF (95%), LCF (88%), and NLF (78%) parents and guardians had heard anti-immigrant statements from the former U.S. president and most (94% ULF, 90% LCF, 86% NLF) believed these measures against immigrants were being enacted or will be enacted. More ULF (75%, 95% confidence interval [CI] 67-81%) reported that these statements made them concerned about their child's safety in the United States compared with 36% (95% CI 28-45%) and 34% (95% CI 26-43%) of LCF and NLF, respectively. More ULF 17% (95% CI 11-24%) said that these statements made them afraid to bring their child for medical care, compared with 5% (95% CI 2-10%) and 3% (95% CI 1-7%) of LCF and NLF, respectively.

CONCLUSIONS

Most parents heard statements against undocumented immigrants by the former U.S. president and most believed measures were being enacted. This rhetoric had a substantial negative impact on ULF parents in terms of safety concerns for their child and fear of accessing health care.

Fears of disclosure and misconceptions regarding domestic violence reporting amongst patients in two US emergency departments

Patients often do not disclose domestic violence (DV) to healthcare providers in emergency departments and other healthcare settings. Barriers to disclosure may include fears and misconceptions about whether, and under what circumstances, healthcare providers report DV to law enforcement and immigration authorities. We sought to assess undocumented Latino immigrants (UDLI), Latino legal residents/citizens (LLRC) and non-Latino legal residents/citizens (NLRC) beliefs about disclosure of DV victimization to healthcare providers and healthcare provider reporting of DV to law enforcement and immigration authorities. From 10/2018-2/2020, we conducted this survey study at two urban emergency departments (EDs) in California. Participants, enrolled by convenience sampling, responded to survey questions adapted from a previously published survey instrument that was developed to assess undocumented immigrant fears of accessing ED care. Our primary outcomes were the proportions of UDLI, LLRC and NLRC who knew of someone who had experienced DV in the past year, whether these DV victims were afraid to access ED care, reasons DV victims were afraid to access ED care, and rates of misconceptions (defined according to current California law) about the consequences of disclosing DV to healthcare providers. Of 667 patients approached, 531 (80%) agreed to participate: 32% UDLI, 33% LLRC, and 35% NLRC. Of the 27.5% of respondents who knew someone who experienced DV in the past year, 46% stated that the DV victim was afraid to seek ED care; there was no significant difference in this rate between groups. The most common fears reported as barriers to disclosure were fear the doctor would report DV to police (31%) and fear that the person perpetrating DV would find out about the disclosure (30.3%). Contrary to our hypothesis, UDLI had lower rates of misconceptions about healthcare provider and law enforcement responses to DV disclosure than LLRC and NLRC. Fear of disclosing DV and misconceptions about the consequences of disclosure of DV to healthcare providers were common, indicating a need for provider, patient, and community education and changes that lower barriers to help-seeking.

Provider and administrator-level perspectives on strategies to reduce fear and improve patient trust in the emergency department in times of heightened immigration enforcement

STUDY OBJECTIVES

Heightened immigration enforcement may induce fear in undocumented patients when coming to the Emergency Department (ED) for care. Limited literature examining health system policies to reduce immigrant fear exists. In this multi-site qualitative study, we sought to assess provider and system-level policies on caring for undocumented patients in three California EDs.

METHODS

We recruited 41 ED providers and administrators from three California EDs (in San Francisco, Oakland, and Sylmar) with large immigrant populations. Participants were recruited using a trusted gatekeeper and snowball sampling. We conducted semi-structured interviews and analyzed the transcripts using constructivist grounded theory.

RESULTS

We interviewed 10 physicians, 11 nurses, 9 social workers, and 11 administrators, and identified 7 themes. Providers described existing policies and recent policy changes that facilitate access to care for undocumented patients. Providers reported that current training and communication around policies is limited, there are variations between who asks about and documents status, and there remains uncertainty around policy details, laws, and jurisdiction of staff. Providers also stated they are taking an active role in building safety and trust and see their role as supporting undocumented patients.

CONCLUSIONS

This study introduces ED-level health system perspectives and recommendations for caring for undocumented patients. There is a need for active, multi-disciplinary ED policy training, clear policy details including the extent of providers' roles, protocols on the screening and documentation of status, and continual reassessment of our health systems to reduce fear and build safety and trust with our undocumented communities.

Fear of discovery as a deterrent to undocumented Latinx immigrants' reporting of crimes and the effects of political rhetoric

OBJECTIVES

Comparing undocumented Latinx immigrants (UDLI), Latinx citizens/residents (LCR), and non-Latinx citizens/residents (NLCR), we sought to assess rates of crime victimization, fear of reporting crimes, causes of this fear, and whether political rhetoric from the U.S. President had changed the reporting of crimes.

METHODS

From October 2018 to February 2020, we conducted this in-person survey study, enrolling similar numbers of UDLI, LCR, and NLCR patients at two urban county hospital emergency departments (EDs) in San Francisco and Oakland, California. Our primary outcomes were responses to key survey questions regarding crime victimization, fear of reporting crimes and the effects of anti-immigrant rhetoric on reporting crimes.

RESULTS

Of 667 patients approached, 531 (80%) participated and six participants were excluded: 165 (31.3%) were UDLI, 183 (34.7%) were LCR, and 177 (33.6%) were NLCR. Similar percentages of UDLI (34%), LCR (32%), and NLCR (39%) knew of someone (themselves, friends, or family) who was a victim of a crime. Similar percentages of UDLI (41%), LCR (46%), and NLCR (41%) stated that these victims were afraid to report this crime to the police. The primary reason for this fear in UDLI was fear of discovery and deportation (30%). Similar percentages of UDLI (63%), LCR (58%), and NLCR (46%) ultimately reported the crime to the police. Most (85%) respondents had heard the U.S. President's statements about measures against immigrants; 54% reported that they believe that because of these statements, people are more afraid to report a crime to the police.

CONCLUSIONS

Fear of reporting crimes is common in ED patients. The most common fear in UDLI is fear of discovery and deportation. Political rhetoric against immigrants contributes to this fear.

Anxiety, PTSD, and stressors in medical students during the initial peak of the COVID-19 pandemic

Purpose

To assess psychological effects of the initial peak phase of the COVID-19 pandemic on United States (US) medical students in clinical training to anticipate sequelae and prepare for future outbreaks.

Methods

Authors emailed a cross-sectional survey in April-May, 2020 to students in clinical training years at six US medical schools which included validated General Anxiety Disorder (GAD-7) and Primary Care-PTSD (PC-PTSD-5) screening tools, and asked students about pandemic-related stress and specific concerns. Authors used quantitative and thematic analysis to present results.

Results

Of 2511 eligible students, 741 responded (29.5%). Most students (84.1%) reported at least “somewhat” increased levels of stress and anxiety related to the pandemic. On the GAD-7, 34.3% showed mild, 16.1% moderate, and 9.5% severe anxiety symptoms, with 39.6% demonstrating no/minimal symptoms. One quarter (25.4%) screened positive for PTSD risk symptoms. Top concerns of students chosen from a pre-populated list included inadequate COVID-19 testing, undiagnosed or asymptomatic spread and racial or other disparities in the pandemic. In thematic analysis, students’ reactions to removal from clinical learning included: understanding the need to conserve PPE (32.2%), a desire to help (27.7%), worry over infectious risk to others (25.4%) and self (21.2%), and lost learning opportunities (22.5%). Female students were significantly more likely to report anxiety and PTSD risk symptoms. Asian students had a greater risk of moderate anxiety and those underrepresented in medicine (UIM) had greater risk of moderate and severe anxiety symptoms compared to white students.

Conclusions

During the initial peak phase of COVID-19, over 60% of US medical students screened positive for pandemic-related anxiety and one quarter were at risk for PTSD. Female and UIM students were significantly more affected. Medical schools should consider broad support of students, and targeted outreach to female and UIM students.

A Review of COVID-19-Related Publications and Lag Times During the First Six Months of the Year 2020

INTRODUCTION

Considering the need for information regarding approaches to prevention and treatment of coronavirus disease 2019 (COVID-19), we sought to determine publication lag times of COVID-19-related original research articles published in top general medicine and emergency medicine (EM) journals. We further sought to characterize the types of COVID-19 publications within these journals.

METHODS

We reviewed 125 top-ranked general medicine journals and 20 top-ranked EM-specific journals for COVID-19-related publications. We abstracted article titles and manuscript details for each COVID-19-related article published between January 1-June 30, 2020, and categorized articles as one of the following: original research; case report; review; or commentary. We abstracted data for preprint publications over the same time period and determined whether articles from the general medicine and EM journals had been previously published as preprint articles. Our primary outcomes were the following: 1) lag time (days) between global cumulative World Health Organization (WHO)-confirmed cases of COVID-19 and publications; 2) lag times between preprint article publication and peer-reviewed journal publication; and 3) lag times between submission and publication in peer-reviewed journals. Our secondary outcome was to characterize COVID-19-related publications.

RESULTS

The first original research publications appeared in a general medicine journal 20 days and in an EM journal 58 days after the first WHO-confirmed case of COVID-19. We found median and mean lag times between preprint publications and journal publications of 32 days (19, 49) and 36 days (22) for general medicine journals, and 26 days (16, 36) and 25 days (13) for EM journals. Median and mean lag times between submission and publication were 30 days (19, 45) and 35 days (13) for general medicine journals, and 23 days (11, 39) and 27 days (19) for EM journals. Of 2530 general medicine journal articles and 351 EM journal articles, 28% and 23.6% were original research. We noted substantial closing of the preprint to peer-reviewed publication (160 days pre-pandemic) and peer-reviewed journal submission to publication (194 days pre-pandemic) lag times for COVID-19 manuscripts.

CONCLUSION

We found a rapid and robust response with shortened publication lag times to meet the need for the publication of original research and other vital medical information related to COVID-19 during the first six months of 2020.

The Rapid Evaluation of COVID-19 Vaccination in Emergency Departments for Underserved Patients Study

Study objective

Emergency departments (EDs) often serve vulnerable populations who may lack primary care and have suffered disproportionate COVID-19 pandemic effects. Comparing patients having and lacking a regular source of medical care and other ED patient characteristics, we assessed COVID-19 vaccine hesitancy, reasons for not wanting the vaccine, perceived access to vaccine sites, and willingness to get the vaccine as part of ED care.

Methods

This was a cross-sectional survey conducted from December 10, 2020, to March 7, 2021, at 15 safety net US EDs. Primary outcomes were COVID-19 vaccine hesitancy, reasons for vaccine hesitancy, and sites (including EDs) for potential COVID-19 vaccine receipt.

Results

Of 2,575 patients approached, 2,301 (89.4%) participated. Of the 18.4% of respondents who lacked a regular source of medical care, 65% used the ED as their usual source of health care. The overall rate of vaccine hesitancy was 39%; the range among the 15 sites was 28% to 58%. Respondents who lacked a regular source of medical care were more commonly vaccine hesitant than those who had a regular source of medical care (47% versus 38%, 9% difference, 95% confidence interval 4% to 14%). Other characteristics associated with greater vaccine hesitancy were younger age, female sex, Black race, Latinx ethnicity, and not having received an influenza vaccine in the past 5 years. Of the 61% who would accept a COVID-19 vaccine, 21% stated that they lacked a primary physician or clinic at which to receive it; the vast majority (95%) of these respondents would accept the COVID-19 vaccine as part of their care in the ED.

Conclusion

ED patients who lack a regular source of medical care are particularly hesitant regarding COVID-19 vaccination. Most COVID-19 vaccine acceptors would accept it as part of their care in the ED. EDs may play pivotal roles in COVID-19 vaccine messaging and delivery to highly vulnerable populations.

Anti-immigrant Rhetoric and the Experiences of Latino Immigrants in the Emergency Department

Introduction

Anti-immigrant rhetoric and increased enforcement of immigration laws have induced worry and safety concerns among undocumented Latino immigrants (UDLI) and legal Latino residents/citizens (LLRC), with some delaying the time to care.1 In this study, we conducted a qualitative analysis of statements made by emergency department (ED) patients – a majority of whom were UDLI and LLRC – participating in a study to better understand their experiences and fears with regard to anti-immigrant rhetoric, immigration enforcement, and ED utilization.

Methods

We conducted a multi-site study, surveying patients in three California safety-net EDs serving large immigrant populations from June 2017–December 2018. Of 1684 patients approached, 1337 (79.4%) agreed to participate; when given the option to provide open-ended comments, 260 participants provided perspectives about their experiences during the years immediately following the 2016 United States presidential election. We analyzed these qualitative data using constructivist grounded theory.

Results

We analyzed comments from 260 individuals. Among ED patients who provided qualitative data, 59% were women and their median age was 45 years (Interquartile range 33–57 years). Undocumented Latino immigrants comprised 49%, 31% were LLRC, and 20% were non-Latino legal residents. As their primary language, 68% spoke Spanish. We identified six themes: fear as a barrier to care (especially for UDLI); the negative impact of fear on health and wellness (physical and mental health, delays in care); factors influencing fear (eg, media coverage); and future solutions, including the need for increased communication about rights.

Conclusion

Anti-immigrant rhetoric during the 2016 US presidential campaign contributed to fear and safety concerns among UDLI and LLRC accessing healthcare. This is one of the few studies that captured firsthand experiences of UDLI in the ED. Our findings revealed fear-based barriers to accessing emergency care, protective and contributing factors to fear, and the negative impact of fear. There is a need for increased culturally informed patient communication about rights and resources, strategic media campaigns, and improved access to healthcare for undocumented individuals.

Emergency physician stressors, concerns, and behavioral changes during COVID-19: A longitudinal study

Objectives

The objective was to provide a longitudinal assessment of anxiety levels and work and home concerns of U.S. emergency physicians during the COVID‐19 pandemic.

Methods

We performed a longitudinal, cross‐sectional email survey of clinically active emergency physicians (attending, fellow, and resident) at seven academic emergency departments. Follow‐up surveys were sent 4 to 6 weeks after the initial survey and assessed the following: COVID‐19 patient exposure, availability of COVID‐19 testing, levels of home and workplace anxiety/stress, changes in behaviors, and performance on a primary care posttraumatic stress disorder screen (PC‐PTSD‐5). Logistic regression explored factors associated with a high PC‐PTSD‐5 scale score (≥3), indicating increased risk for PTSD.

Results

Of the 426 surveyed initial respondents, 262 (61.5%) completed the follow‐up survey. While 97.3% (255/262) reported treating suspected COVID‐19 patients, most physicians (162/262, 61.8%) had not received testing themselves. In follow‐up, respondents were most concerned about the relaxing of social distancing leading to a second wave (median score = 6, IQR = 4–7). Physicians reported a consistently high ability to order COVID‐19 tests for patients (median score = 6, IQR = 5–7) and access to personal protective equipment (median score = 6, IQR = 5–6). Women physicians were more likely to score ≥ 3 than men on the PC‐PTSD‐5 screener on the initial survey (43.3% vs. 22.5%; Δ 20.8%, 95% confidence interval [CI] = 9.3% to 31.5%), and despite decreases in overall proportions, this discrepancy remained in follow‐up (34.7% vs. 16.8%; Δ 17.9%, 95% CI = 7.1% to 28.1%). In examining the relationship between demographics, living situations, and institution location on having a PC‐PTSD‐5 score ≥ 3, only female sex was associated with a PC‐PTSD‐5 score ≥ 3 (adjusted odds ratio = 2.48, 95% CI = 1.28 to 4.79).

Conclusions

While exposure to suspected COVID‐19 patients was nearly universal, stress levels in emergency physicians decreased with time. At both initial and follow‐up assessments, women were more likely to test positive on the PC‐PTSD‐5 screener compared to men.

Symptoms of Anxiety, Burnout, and PTSD and the Mitigation Effect of Serologic Testing in Emergency Department Personnel During the COVID-19 Pandemic

Study Objective

Among a comprehensive range of frontline emergency department health care personnel, we assessed symptoms of anxiety and burnout, specific coronavirus disease 2019 (COVID-19) work-related stressors, and risk for post-traumatic stress disorder (PTSD). We also determined whether COVID-19 serologic testing of HCP decreased their self-reported anxiety.

Methods

In a prospective cohort study from May 13, 2020, to July 8, 2020, we used electronic surveys to capture participant self-reported symptoms before and after serologic testing for anti-SARS-CoV-2 immunoglobulin G antibodies. Participants were physicians, nurses, advanced practice providers, and nonclinical ED personnel at 20 geographically diverse United States EDs. We evaluated these domains: 1) the effects of the COVID-19 pandemic on overall stress and anxiety; 2) COVID-19-related work stressors; 3) burnout; and 4) PTSD risk (measured using the Primary Care-PTSD Screen for DSM-5, a 5-item screening instrument in which a score of ≥3 signifies high risk for PTSD). We also assessed perceptions of whether results of COVID-19 antibody testing decreased participants’ self-reported anxiety.

Results

Of 1,606 participants, 100% and 88% responded to the baseline and follow-up surveys, respectively. At baseline, approximately half (46%) reported symptoms of emotional exhaustion and burnout from their work, and 308 (19.2%, 95% confidence interval [CI] 17.3% to 21.1%) respondents screened positive for increased PTSD risk. Female respondents were more likely than males to screen positive (odds ratio [OR] 2.03, 95% CI 1.49 to 2.78). Common concerns included exposing their family and the health of coworkers diagnosed with COVID-19. After receiving antibody test results, 54% (95% CI 51.8 to 56.7) somewhat agreed, agreed, or strongly agreed that knowledge of their immune status had decreased their anxiety. A positive serology result indicating prior SARS-CoV-2 infection was associated with a higher likelihood of reporting decreased anxiety (2.83, 95% CI 1.37 to 5.83).

Conclusion

Symptoms of anxiety and burnout were prevalent across the spectrum of ED staff during the COVID-19 pandemic. One-fifth of ED personnel appeared to be at risk for PTSD. Increased provision of serologic testing may help to mitigate anxiety.

NAloxone CARdiac Arrest Decision Instruments (NACARDI) for targeted antidotal therapy in occult opioid overdose precipitated cardiac arrest

BACKGROUND

We have recently demonstrated that a significant proportion of fatal out-of-hospital cardiac arrests (OHCAs) are precipitated by occult overdose, which could benefit from antidote therapy administered adjunctively with other cardiac resuscitation measures. We sought to develop simple decision instruments that EMS providers and other first responders can use to rapidly identify occult opioid overdose-associated OHCAs.

METHODS

We examined data from February 2011 through December 2017 in the Postmortem Systematic Investigation of Sudden Cardiac Death study, in which San Francisco (California) County EMS-attended OHCA deaths received autopsy and expert panel adjudication of cause of death. Using classification tree analyses, we derived highly sensitive and specific decision instruments that predicted our primary outcome of occult opioid OD-associated OHCA. We then calculated screening performance characteristics of these instruments.

RESULTS

Of 767 OHCA deaths, 80 (10.4%) were associated with occult opioid overdose. Of the eight models with 100% sensitivity for opioid overdose-associated cardiac arrest, the highest specificity model (23.4%, 95% confidence interval [CI] 20.3-26.7%) was age < 60 years OR race = black or non-Latinx white OR arrest in public place. The highest specificity instrument (96.3%, 95% CI 94.6-97.5%) consisting of age < 60 years AND race = black or non-Latinx white AND unwitnessed arrest AND female sex had 25% (95% CI 16-35.9%) sensitivity.

CONCLUSIONS

We have derived simple decision instruments that can identify patients whose OHCA precipitant was occult opioid overdose. These instruments may be used to guide selective administration of the antidote naloxone in OHCA resuscitations.

Effects of the COVID-19 pandemic on medical students: a multicenter quantitative study

BACKGROUND

The COVID-19 pandemic disrupted the United States (US) medical education system with the necessary, yet unprecedented Association of American Medical Colleges (AAMC) national recommendation to pause all student clinical rotations with in-person patient care. This study is a quantitative analysis investigating the educational and psychological effects of the pandemic on US medical students and their reactions to the AAMC recommendation in order to inform medical education policy.

METHODS

The authors sent a cross-sectional survey via email to medical students in their clinical training years at six medical schools during the initial peak phase of the COVID-19 pandemic. Survey questions aimed to evaluate students' perceptions of COVID-19's impact on medical education; ethical obligations during a pandemic; infection risk; anxiety and burnout; willingness and needed preparations to return to clinical rotations.

RESULTS

Seven hundred forty-one (29.5%) students responded. Nearly all students (93.7%) were not involved in clinical rotations with in-person patient contact at the time the study was conducted. Reactions to being removed were mixed, with 75.8% feeling this was appropriate, 34.7% guilty, 33.5% disappointed, and 27.0% relieved. Most students (74.7%) agreed the pandemic had significantly disrupted their medical education, and believed they should continue with normal clinical rotations during this pandemic (61.3%). When asked if they would accept the risk of infection with COVID-19 if they returned to the clinical setting, 83.4% agreed. Students reported the pandemic had moderate effects on their stress and anxiety levels with 84.1% of respondents feeling at least somewhat anxious. Adequate personal protective equipment (PPE) (53.5%) was the most important factor to feel safe returning to clinical rotations, followed by adequate testing for infection (19.3%) and antibody testing (16.2%).

CONCLUSIONS

The COVID-19 pandemic disrupted the education of US medical students in their clinical training years. The majority of students wanted to return to clinical rotations and were willing to accept the risk of COVID-19 infection. Students were most concerned with having enough PPE if allowed to return to clinical activities.

Academic Emergency Medicine Physicians' Anxiety Levels, Stressors, and Potential Stress Mitigation Measures During the Acceleration Phase of the COVID-19 Pandemic

Objective

The objective was to assess anxiety and burnout levels, home life changes, and measures to relieve stress of U.S. academic emergency medicine (EM) physicians during the COVID‐19 pandemic acceleration phase.

Methods

We sent a cross‐sectional e‐mail survey to all EM physicians at seven academic emergency departments. The survey incorporated items from validated stress scales and assessed perceptions and key elements in the following domains: numbers of suspected COVID‐19 patients, availability of diagnostic testing, levels of home and workplace anxiety, severity of work burnout, identification of stressors, changes in home behaviors, and measures to decrease provider anxiety.

Results

A total of 426 (56.7%) EM physicians responded. On a scale of 1 to 7 (1 = not at all, 4 = somewhat, and 7 = extremely), the median (interquartile range) reported effect of the pandemic on both work and home stress levels was 5 (4–6). Reported levels of emotional exhaustion/burnout increased from a prepandemic median (IQR) of 3 (2–4) to since the pandemic started a median of 4 (3–6), with a difference in medians of 1.8 (95% confidence interval = 1.7 to 1.9). Most physicians (90.8%) reported changing their behavior toward family and friends, especially by decreasing signs of affection (76.8%). The most commonly cited measures cited to alleviate stress/anxiety were increasing personal protective equipment (PPE) availability, offering rapid COVID‐19 testing at physician discretion, providing clearer communication about COVID‐19 protocol changes, and assuring that physicians can take leave for care of family and self.

Conclusions

During the acceleration phase, the COVID‐19 pandemic has induced substantial workplace and home anxiety in academic EM physicians, and their exposure during work has had a major impact on their home lives. Measures cited to decrease stress include enhanced availability of PPE, rapid turnaround testing at provider discretion, and clear communication about COVID‐19 protocol changes.

A Review of Journal Impact Metrics and Characteristics to Assist Emergency Medicine Investigators with Manuscript Submission Decisions

Introduction

A crucial, yet subjective and non-evidence-based, decision for researchers is where to submit their original research manuscripts. The approach of submitting to journals in descending order of impact factor (IF) is a common but imperfect strategy. The validity of the IF as a measure of journal quality and significance is suspect, and a number of other journal impact scores have emerged, such that no one scale is universally accepted. Furthermore, practical considerations, such as likelihood of manuscript acceptance rates and times for decisions, may influence how authors prioritize journals. In this report, we sought to 1) review emergency medicine (EM) journal impact metrics, and 2) provide a comprehensive list of pertinent journal characteristics that may influence researchers’ choice of submission.

Methods

We systematically reviewed five impact metrics (IF, H Index, CiteScore, Source-Normalized Impact per Paper, and SCImago Journal Rank) and other relevant characteristics of 20 EM journals.

Results

We found good to excellent agreement in ordinal rankings of four of the journal impact metrics, as measured by the Spearman rank correlation coefficient. The median acceptance rate for original research manuscripts in the EM category was 25% (interquartile range [IQR] 18, 31%), and the median initial decision time was 33 days (IQR 18, 56 days). Fourteen EM journals (70%) accepted brief reports, and 15 (75%) accepted case reports/images.

Conclusion

We recommend replication, expansion, and formalization of this repository of information for EM investigators in a continuously updated, open-access forum sponsored by an independent organization.

Blunt Traumatic Aortic Injury in the Pan-scan Era

BACKGROUND

In the era of frequent head-to-pelvis computed tomography (CT) for adult blunt trauma evaluation, we sought to update teachings regarding aortic injury by determining 1) the incidence of aortic injury; 2) the proportion of patients with isolated aortic injury (without other concomitant thoracic injury); 3) the clinical implications of aortic injury (hospital mortality, length of stay [LOS], and rate of surgical interventions); and 4) the screening value of traditional risk factors/markers (such as high-energy mechanism and widened mediastinum on chest x-ray [CXR]) for aortic injury, compared to newer criteria from the recently developed NEXUS Chest CT decision instrument (DI).

METHODS

We conducted a preplanned analysis of patients prospectively enrolled in the NEXUS Chest studies at 10 Level I trauma centers with the following inclusion criteria: age > 14 years, blunt trauma within 6 hours of ED presentation, and receiving chest imaging during ED trauma evaluation.

RESULTS

Of 24,010 enrolled subjects, 42 (0.17%, 95% confidence interval [CI] = 0.13% to 0.24%) had aortic injury. Most patients (79%, 95% CI = 64% to 88%) had an associated thoracic injury, with rib fractures, pneumothorax/hemothorax, and pulmonary contusion occurring most frequently. Compared to patients without aortic injury this cohort had similar mortality (9.5%, 95% CI = 3.8% to 22.1% vs. 5.8%, 95% CI = 5.4% to 6.3%), longer median hospital LOS (11 days vs. 3 days, p < 0.01), and higher median Injury Severity Score (29 vs. 5, p < 0.001). High-energy mechanism and widened mediastinum on CXR had low sensitivity for aortic injury (76% [95% CI = 62% to 87%] and 33% [95% CI = 21% to 49%], respectively), compared to the NEXUS Chest CT DI (sensitivity 100% [95% CI = 92% to 100%]).

CONCLUSIONS

Aortic injury is rare in adult ED blunt trauma patients who survive to receive imaging. Most ED aortic injury patients have associated thoracic injuries and survive to hospital discharge. Widened mediastinum on CXR and high-energy mechanism have relatively low screening sensitivity for aortic injury, but the NEXUS Chest DI detected all cases.

Thoracic Spine Fracture in the Panscan Era

STUDY OBJECTIVE

In the current era of frequent chest computed tomography (CT) for adult blunt trauma evaluation, many minor injuries are diagnosed, potentially rendering traditional teachings obsolete. We seek to update teachings in regard to thoracic spine fracture by determining how often such fractures are observed on CT only (ie, not visualized on preceding trauma chest radiograph), the admission rate, mortality, and hospital length of stay of thoracic spine fracture patients, and how often thoracic spine fractures are clinically significant.

METHODS

This was a preplanned analysis of prospectively collected data from the NEXUS Chest CT study conducted from 2011 to 2014 at 9 Level I trauma centers. The inclusion criteria were older than 14 years, blunt trauma occurring within 6 hours of emergency department (ED) presentation, and chest imaging (radiography, CT, or both) during ED evaluation.

RESULTS

Of 11,477 enrolled subjects, 217 (1.9%) had a thoracic spine fracture; 181 of the 198 thoracic spine fracture patients (91.4%) who had both chest radiograph and CT had their thoracic spine fracture observed on CT only. Half of patients (49.8%) had more than 1 level of thoracic spine fracture, with a mean of 2.1 levels (SD 1.6 levels) of thoracic spine involved. Most patients (62%) had associated thoracic injuries. Compared with patients without thoracic spine fracture, those with it had higher admission rates (88.5% versus 47.2%; difference 41.3%; 95% confidence interval 36.3% to 45%), higher mortality (6.3% versus 4.0%; difference 2.3%; 95% confidence interval 0 to 6.7%), and longer length of stay (median 9 versus 6 days; difference 3 days; P<.001). However, thoracic spine fracture patients without other thoracic injury had mortality similar to that of patients without thoracic spine fracture (4.6% versus 4%; difference 0.6%; 95% confidence interval -2.5% to 8.6%). Less than half of thoracic spine fractures (47.4%) were clinically significant: 40.8% of patients received thoracolumbosacral orthosis bracing, 10.9% had surgery, and 3.8% had an associated neurologic deficit.

CONCLUSION

Thoracic spine fracture is uncommon. Most thoracic spine fractures are associated with other thoracic injuries, and mortality is more closely related to these other injuries than to the thoracic spine fracture itself. More than half of thoracic spine fractures are clinically insignificant; surgical intervention is uncommon and neurologic injury is rare.

Prevalence of Intracranial Injury in Adult Patients With Blunt Head Trauma With and Without Anticoagulant or Antiplatelet Use

STUDY OBJECTIVE

We determine the prevalence of significant intracranial injury among adults with blunt head trauma who are receiving preinjury anticoagulant or antiplatelet medications.

METHODS

This was a multicenter, prospective, observational study conducted from December 2007 to December 2015. Patients were enrolled in 3 emergency departments (EDs) in the United States. Adults with blunt head trauma who underwent neuroimaging in the ED were included. Use of preinjury aspirin, clopidogrel, and warfarin was recorded. Data on direct oral anticoagulants were not specifically recorded. The primary outcome was prevalence of significant intracranial injury on neuroimaging. The secondary outcome was receipt of neurosurgical intervention.

RESULTS

Among 9,070 patients enrolled in this study, the median age was 53.8 years (interquartile range 34.7 to 74.3 years) and 60.7% were men. A total of 1,323 patients (14.6%) were receiving antiplatelet medications or warfarin, including 635 receiving aspirin alone, 109 clopidogrel alone, and 406 warfarin alone. Compared with that of patients without any coagulopathy, the relative risk of significant intracranial injury was 1.29 (95% confidence interval [CI] 0.88 to 1.87) for patients receiving aspirin alone, 0.75 (95% CI 0.24 to 2.30) for those receiving clopidogrel alone, and 1.88 (95% CI 1.28 to 2.75) for those receiving warfarin alone. The relative risk of significant intracranial injury was 2.88 (95% CI 1.53 to 5.42) for patients receiving aspirin and clopidogrel in combination.

CONCLUSION

Patients receiving preinjury warfarin or a combination of aspirin and clopidogrel were at increased risk for significant intracranial injury, but not those receiving aspirin alone. Clinicians should have a low threshold for neuroimaging when evaluating patients receiving warfarin or a combination of aspirin and clopidogrel.

Mucinous cystic neoplasms of the liver: presence of biliary communication

A 35-year-old woman was referred for a symptomatic liver mass. Diagnostic workup detected a septated cyst located centrally in the liver measuring 10 × 7 cm. The cyst had gradually increased in size from previous studies with new intrahepatic biliary dilation. Due to concern for malignancy and symptomatic presentation of the patient, a partial central hepatectomy was performed. Pathology revealed a smooth-walled, multiloculated cyst lined with mucinous epithelium and ovarian-type stroma. The diagnosis of low-grade mucinous cystic neoplasm of the liver (MCN-L) was made. Characteristics of MCN-L have not been elucidated due to its rarity.

Declared impact of the US President's statements and campaign statements on Latino populations' perceptions of safety and emergency care access

Statements about building walls, deportation and denying services to undocumented immigrants made during President Trump’s presidential campaign and presidency may induce fear in Latino populations and create barriers to their health care access. To assess how these statements relate to undocumented Latino immigrants’ (UDLI) and Latino legal residents/citizens’ (LLRC) perceptions of safety and their presentations for emergency care, we conducted surveys of adult patients at three county emergency departments (EDs) in California from June 2017 to December 2018. Of 1,684 patients approached, 1,337 (79.4%) agreed to participate: 34.3% UDLI, 36.9% LLRC, and 29.8% non-Latino legal residents/citizens (NLRC). The vast majority of UDLI (95%), LLRC (94%) and NLRC (85%) had heard statements about immigrants. Most UDLI (89%), LLRC (88%) and NLRC (87%) either thought that these measures were being enacted now or will be enacted in the future. Most UDLI and half of LLRC reported that these statements made them feel unsafe living in the US, 75% (95% CI 70–80%) and 51% (95% CI 47–56%), respectively. More UDLI reported that these statements made them afraid to come to the ED (24%, 95% CI 20–28%) vs LLRC (4.4%, 95% CI 3–7%) and NLRC (3.5%, 95% CI 2–6%); 55% of UDLI with this fear stated it caused them to delay coming to the ED (median delay 2–3 days). The vast majority of patients in our California EDs have heard statements during the 2016 presidential campaign or from President Trump about measures against undocumented immigrants, which have induced worry and safety concerns in both UDLI and LLRC patients. Exposure to these statements was also associated with fear of accessing emergency care in some UDLIs. Given California’s sanctuary state status, these safety concerns and ED access fears may be greater in a nationwide population of Latinos.

Combining qSOFA criteria with initial lactate levels: Improved screening of septic patients for critical illness

OBJECTIVE

To determine if the addition of lactate to Quick Sequential Organ Failure Assessment (qSOFA) scoring improves emergency department (ED) screening of septic patients for critical illness.

METHODS

This was a multicenter retrospective cohort study of consecutive adult patients admitted to the hospital from the ED with infectious disease-related illnesses. We recorded qSOFA criteria and initial lactate levels in the first 6 h of ED stay. Our primary outcome was a composite of hospital death, vasopressor use, and intensive care unit stay ≤72 h of presentation. Diagnostic test characteristics were determined for: 1) lactate levels ≥2 and ≥4; 2) qSOFA scores ≥1, ≥2, and =3; and 3) combinations of these.

RESULTS

Of 3743 patients, 2584 had a lactate drawn ≤6 h of ED stay and 18% met the primary outcome. The qSOFA scores were ≥1, ≥2, and =3 in 59.2%, 22.0%, and 5.3% of patients, respectively, and 34.4% had a lactate level ≥2 and 7.9% had a lactate level ≥4. The combination of qSOFA ≥1 OR Lactate ≥2 had the highest sensitivity, 94.0% (95% CI: 91.3-95.9).

CONCLUSIONS

The combination of qSOFA ≥1 OR Lactate ≥2 provides substantially improved sensitivity for the screening of critical illness compared to isolated lactate and qSOFA thresholds.
