Racial and Socioeconomic Disparities Evident in Inappropriate Antibiotic Prescribing in the Emergency Department.

STUDY OBJECTIVE: Inappropriate antibiotic prescribing for acute respiratory tract infections is a common source of low-value care in the emergency department (ED). Racial and socioeconomic disparities have been noted in episodes of low-value care, particularly in children. We evaluated whether prescribing rates for acute respiratory tract infections when antibiotics would be inappropriate by guidelines differed by race and socioeconomics. METHODS: A retrospective cross-sectional analysis of adult and pediatric patient encounters in the emergency department (ED) between 2015 and 2023 at 5 hospitals for acute respiratory tract infections that did not require antibiotics by guidelines. Multivariable regression was used to calculate the risk ratio between race, ethnicity, and area deprivation index and inappropriate antibiotic prescribing, controlling for patient age, sex, and relevant comorbidities. RESULTS: A total of 147,401 ED encounters (55% pediatric, 45% adult) were included. At arrival, 4% patients identified as Asian, 50% as Black, 5% as Hispanic, and 23% as White. Inappropriate prescribing was noted in 7.6% of overall encounters, 8% for Asian patients, 6% for Black patients, 5% for Hispanic patients, and 12% for White patients. After adjusting for age, sex, comorbidities, and area deprivation index, White patients had a 1.32 (95% confidence interval, 1.26 to 1.38) higher likelihood of receiving a prescription compared with Black patients. Patients residing in areas of greater socioeconomic deprivation, regardless of race and ethnicity, had a 0.74 (95% confidence interval, 0.70 to 0.78) lower likelihood of receiving a prescription. CONCLUSION: Our results suggest that although overall inappropriate prescribing was relatively low, White patients and patients from wealthier areas were more likely to receive an inappropriate antibiotic prescription.

Didn't put a label on it: Examining intimate partner strangulation within a diagnostic framework.

AIMS: The aim was to examine and describe women's emergency department visits and care-seeking experiences, including recognition, evaluation and communication of symptoms, injuries and health risks after non-fatal intimate partner strangulation. DESIGN: Using a diagnostic process framework, this mixed-methods study explores concordance and discordance of interview and medical records data to highlight opportunities for clinical diagnostic improvement. METHODS: In-depth, semi-structured interviews with women after an emergency department visit for non-fatal intimate partner strangulation, concurrent with medical records reviews, were conducted between March 2018 and January 2019. A constant comparative approach was used to analyse interview and medical record data using an a priori codebook designed based on the National Academies of Science, Engineering and Medicine's conceptual model of the diagnostic process and prior intimate partner violence research. RESULTS: Interviews reflected participants did not have a sense of long-term health risks from their strangulation beyond addressing emotional trauma. Women noted that forensic and emergency nursing support was treatment in and of itself that allowed them to be heard and validated. Medical record clinical impressions and final diagnoses included domestic violence, domestic abuse or sexual assault, but not specifically strangulation. CONCLUSION: This study contributes to the growing literature regarding strangulation diagnosis and care. Our findings provide new details of women's emergency department care-seeking experiences which, whilst overall aligned with medical records documentation, were not reflected in final diagnostic impressions nor in patient recollection of long-term health risks. IMPACT: Nurses are strongly positioned as clinical practice leaders and policy advocates to improve collective responses to this dangerous violence mechanism. Actions such as improving patient education, referral and follow-up options to better communication and address long-term strangulation risk are one example. Further research on non-fatal intimate partner strangulation and care-seeking is warranted to expand this knowledge, particularly in longitudinal cohorts and varied geographical areas.

Demographic and clinical correlates of acute and convalescent SARS-CoV-2 infection among patients of a U.S. emergency department.

BACKGROUND: Emergency Departments (EDs) have served as critical surveillance sites for infectious diseases. We sought to determine the prevalence and temporal trends of acute (by PCR) and convalescent (by antibody [Ab]) SARS-CoV-2 infection during the earliest phase of the pandemic among patients in an urban ED in Baltimore City. METHODS: We tested remnant blood samples from 3255 unique ED patients, collected between March 16th and May 31st 2020 for SARS-CoV-2 Ab. PCR for acute SARS-CoV-2 infection from nasopharyngeal swabs was obtained on any patients based on clinical suspicion. Hospital records were abstracted and factors associated with SARS-CoV-2 infection were assessed. RESULTS: Of 3255 ED patients, 8.2% (95%CI: 7.3%, 9.2%) individuals had evidence of SARS-CoV-2 infection; 155 PCR+, 78 Ab+, and 35 who were both PCR+ and Ab+. Prevalence of disease increased throughout the study period, ranging from 3.2% (95%CI: 1.8%, 5.2%) PCR+ and 0.6% (95%CI: 0.1%, 1.8%) Ab+ in March, to 6.2% (95%CI: 5.1%, 7.4%) PCR+ and 4.2% (95%CI: 3.3%, 5.3%) Ab+ in May. The highest SARS-CoV-2 prevalence was found in Hispanic individuals who made up 8.4% (95%CI: 7.4%, 9.4%) of individuals screened, but 35% (95%CI: 29%, 41%) of infections (PCR and/or Ab+). Demographic and clinical factors independently associated with acute infection included Hispanic ethnicity, loss of smell or taste, subjective fever, cough, muscle ache and fever. Factors independently associated with convalescent infection were Hispanic ethnicity and low oxygen saturation. CONCLUSIONS: The burden of COVID-19 in Baltimore City increased dramatically over the 11-week study period and was disproportionately higher among Hispanic individuals. ED-based surveillance methods are important for identifying both acute and convalescent SARS-CoV-2 infections and provides important information regarding demographic and clinical correlates of disease in the local community.

Effect of Vitamin C, Thiamine, and Hydrocortisone on Ventilator- and Vasopressor-Free Days in Patients With Sepsis: The VICTAS Randomized Clinical Trial.

Importance: Sepsis is a common syndrome with substantial morbidity and mortality. A combination of vitamin C, thiamine, and corticosteroids has been proposed as a potential treatment for patients with sepsis. Objective: To determine whether a combination of vitamin C, thiamine, and hydrocortisone every 6 hours increases ventilator- and vasopressor-free days compared with placebo in patients with sepsis. Design, Setting, and Participants: Multicenter, randomized, double-blind, adaptive-sample-size, placebo-controlled trial conducted in adult patients with sepsis-induced respiratory and/or cardiovascular dysfunction. Participants were enrolled in the emergency departments or intensive care units at 43 hospitals in the United States between August 2018 and July 2019. After enrollment of 501 participants, funding was withheld, leading to an administrative termination of the trial. All study-related follow-up was completed by January 2020. Interventions: Participants were randomized to receive intravenous vitamin C (1.5 g), thiamine (100 mg), and hydrocortisone (50 mg) every 6 hours (n = 252) or matching placebo (n = 249) for 96 hours or until discharge from the intensive care unit or death. Participants could be treated with open-label corticosteroids by the clinical team, with study hydrocortisone or matching placebo withheld if the total daily dose was greater or equal to the equivalent of 200 mg of hydrocortisone. Main Outcomes and Measures: The primary outcome was the number of consecutive ventilator- and vasopressor-free days in the first 30 days following the day of randomization. The key secondary outcome was 30-day mortality. Results: Among 501 participants randomized (median age, 62 [interquartile range {IQR}, 50-70] years; 46% female; 30% Black; median Acute Physiology and Chronic Health Evaluation II score, 27 [IQR, 20.8-33.0]; median Sequential Organ Failure Assessment score, 9 [IQR, 7-12]), all completed the trial. Open-label corticosteroids were prescribed to 33% and 32% of the intervention and control groups, respectively. Ventilator- and vasopressor-free days were a median of 25 days (IQR, 0-29 days) in the intervention group and 26 days (IQR, 0-28 days) in the placebo group, with a median difference of -1 day (95% CI, -4 to 2 days; P = .85). Thirty-day mortality was 22% in the intervention group and 24% in the placebo group. Conclusions and Relevance: Among critically ill patients with sepsis, treatment with vitamin C, thiamine, and hydrocortisone, compared with placebo, did not significantly increase ventilator- and vasopressor-free days within 30 days. However, the trial was terminated early for administrative reasons and may have been underpowered to detect a clinically important difference. Trial Registration: ClinicalTrials.gov Identifier: NCT03509350.

United States ED Visits by Adult Women for Nonfatal Intimate Partner Strangulation, 2006 to 2014: Prevalence and Associated Characteristics.

INTRODUCTION: Nonfatal intimate partner strangulation poses significant acute and long-term morbidity risks and also heightens women's risk for future femicide. The lifetime prevalence of nonfatal intimate partner strangulation has been estimated to be approximately 10%, or 11 million women, in the general United States population. Given the potential for significant health risks and serious consequences of strangulation, this study adds to the limited literature by estimating prevalence and describing the associated characteristics of strangulation-related visits among United States ED visits by adult women after intimate partner violence. METHODS: Prevalence estimation as well as simple and multivariable logistic regression analyses were completed using data from the Nationwide Emergency Department Sample spanning the years 2006 to 2014. RESULTS: The prevalence of strangulation codes was estimated at 1.2% of all intimate partner violence visits. Adjusting for visits, hospital characteristics, and visit year, higher odds of strangulation were noted in younger women, metropolitan hospitals, level I/II trauma centers, and non-Northeast regions. Increases in strangulation events among intimate partner violence-related visits in recent years were also observed. DISCUSSION: A relatively low prevalence may reflect an underestimate of true nonfatal intimate partner strangulation visits owing to coding or a very low rate of ED visits for this issue. Higher odds of strangulation among intimate partner violence visits by women in more recent years may be due to increased recognition and documentation by frontline clinicians and coding teams. Continued research is needed to further inform clinical, postcare, and social policy efforts.

Nurse practitioners and physician assistants in emergency medical services who billed independently, 2012-2016.

OBJECTIVE: As nurse practitioners (NPs) and physician assistants (PAs) become an integral part of delivering emergency medical services, we examined the involvement of NPs and PAs who billed independently in emergency departments (EDs). METHODS: We used Medicare provider utilization and payment data from 2012 to 2016 to conduct a retrospective analysis. We examined the changes in the number of each clinician type who billed independently for four common emergency services (CPT codes: 99282-5), the change in their service volume, and the change in their average number of services billed. RESULTS: Between 2012 and 2016, the proportion of NPs and PAs billing independently increased from 18% to 22% for ED visits of low severity (99282), 23% to 29% for visits with moderate severity (99283), 21% to 27% for visits with high severity (99284), 18% to 24% for visit with the highest severity (99285), and 23% to 29% across all four services. The proportion of services provided by emergency physicians decreased from 66% to 63% across all four services, and from 11% to 9% for internists and family physicians. The number of NPs, PAs billing independently, and emergency physicians increased by 65%, 35% and 12% respectively. CONCLUSIONS: NPs and PAs are increasingly billing emergency services of all levels of severity, independent of physicians. This trend is driven by a growing number of NPs and PAs independently billing services, despite a relatively stable number of emergency physicians (excepting the decline in rural areas), and diminished involvement of family physicians and internists in EDs.

Shock index as a predictor of hospital admission and inpatient mortality in a US national database of emergency departments.

STUDY OBJECTIVES: The shock index (SI), defined as the ratio of the heart rate (HR) to the systolic blood pressure (BP), is used as a prognostic tool in trauma and in specific disease states. However, there is scarcity of data about the utility of the SI in the general emergency department (ED)population. Our goal was to use a large national database of EDs in the United States (US) to determine whether the likelihood of inpatient mortality and hospital admission was associated with initial SI at presentation. METHODS: Data from the National Hospital Ambulatory Medical Care Survey were retrospectively reviewed to obtain a weighted sample of all US ED visits between 2005 and 2010. All adults >18 years old who survived the ED visit were included, regardless of their chief complaint. Likelihood ratios (LR) were calculated for a range of SI values, in order to determine SI thresholds most predictive of hospital admission and inpatient mortality. +LRs >5 were considered to be clinically significant. RESULTS: A total of 526 455 251 adult patient encounters were included in the analysis. 56.9% were women, 73.9% were white and 53.2% were between the ages of 18 and 44 years. 88 326 638 (15.7%) unique ED visits resulted in hospital admission and 1 927 235 (2.6%) visits resulted in inpatient mortality. SI>1.3 was associated with a clinically significant increase in both the likelihood of hospital admission (+LR=6.64) and inpatient mortality (+LR=5.67). SI>0.7 and >0.9, the traditional cited cut-offs, were only associated with marginal increases (+LR= 1.13; 1.54 for SI>0.7 and +LR=1.95; 2.59 for SI>0.9 for hospital admission and inpatient mortality, respectively). CONCLUSIONS: In this largest retrospective study to date on SI in the general ED population, we demonstrated that initial SI at presentation to the ED could potentially be useful in predicting the likelihood of hospital admission and inpatient mortality, which could help guide rapid and accurate acuity designation, resource allocation and disposition.

Accuracy and Reliability of Emergency Department Triage Using the Emergency Severity Index: An International Multicenter Assessment.

STUDY OBJECTIVE: We assess accuracy and variability of triage score assignment by emergency department (ED) nurses using the Emergency Severity Index (ESI) in 3 countries. In accordance with previous reports and clinical observation, we hypothesize low accuracy and high variability across all sites. METHODS: This cross-sectional multicenter study enrolled 87 ESI-trained nurses from EDs in Brazil, the United Arab Emirates, and the United States. Standardized triage scenarios published by the Agency for Healthcare Research and Quality (AHRQ) were used. Accuracy was defined by concordance with the AHRQ key and calculated as percentages. Accuracy comparisons were made with one-way ANOVA and paired t test. Interrater reliability was measured with Krippendorff's α. Subanalyses based on nursing experience and triage scenario type were also performed. RESULTS: Mean accuracy pooled across all sites and scenarios was 59.2% (95% confidence interval [CI] 56.4% to 62.0%) and interrater reliability was modest (α=.730; 95% CI .692 to .767). There was no difference in overall accuracy between sites or according to nurse experience. Medium-acuity scenarios were scored with greater accuracy (76.4%; 95% CI 72.6% to 80.3%) than high- or low-acuity cases (44.1%, 95% CI 39.3% to 49.0% and 54%, 95% CI 49.9% to 58.2%), and adult scenarios were scored with greater accuracy than pediatric ones (66.2%, 95% CI 62.9% to 69.7% versus 46.9%, 95% CI 43.4% to 50.3%). CONCLUSION: In this multinational study, concordance of nurse-assigned ESI score with reference standard was universally poor and variability was high. Although the ESI is the most popular ED triage tool in the United States and is increasingly used worldwide, our findings point to a need for more reliable ED triage tools.

Machine-Learning-Based Electronic Triage More Accurately Differentiates Patients With Respect to Clinical Outcomes Compared With the Emergency Severity Index.

STUDY OBJECTIVE: Standards for emergency department (ED) triage in the United States rely heavily on subjective assessment and are limited in their ability to risk-stratify patients. This study seeks to evaluate an electronic triage system (e-triage) based on machine learning that predicts likelihood of acute outcomes enabling improved patient differentiation. METHODS: A multisite, retrospective, cross-sectional study of 172,726 ED visits from urban and community EDs was conducted. E-triage is composed of a random forest model applied to triage data (vital signs, chief complaint, and active medical history) that predicts the need for critical care, an emergency procedure, and inpatient hospitalization in parallel and translates risk to triage level designations. Predicted outcomes and secondary outcomes of elevated troponin and lactate levels were evaluated and compared with the Emergency Severity Index (ESI). RESULTS: E-triage predictions had an area under the curve ranging from 0.73 to 0.92 and demonstrated equivalent or improved identification of clinical patient outcomes compared with ESI at both EDs. E-triage provided rationale for risk-based differentiation of the more than 65% of ED visits triaged to ESI level 3. Matching the ESI patient distribution for comparisons, e-triage identified more than 10% (14,326 patients) of ESI level 3 patients requiring up triage who had substantially increased risk of critical care or emergency procedure (1.7% ESI level 3 versus 6.2% up triaged) and hospitalization (18.9% versus 45.4%) across EDs. CONCLUSION: E-triage more accurately classifies ESI level 3 patients and highlights opportunities to use predictive analytics to support triage decisionmaking. Further prospective validation is needed.

The Effect of Medicaid Expansion on Utilization in Maryland Emergency Departments.

STUDY OBJECTIVE: A proposed benefit of expanding Medicaid eligibility under the Patient Protection and Affordable Care Act (ACA) was a reduction in emergency department (ED) utilization for primary care needs. Pre-ACA studies found that new Medicaid enrollees increased their ED utilization rates, but the effect on system-level ED visits was less clear. Our objective was to estimate the effect of Medicaid expansion on aggregate and individual-based ED utilization patterns within Maryland. METHODS: We performed a retrospective cross-sectional study of ED utilization patterns across Maryland, using data from Maryland's Health Services Cost Review Commission. We also analyzed utilization differences between pre-ACA (July 2012 to December 2013) uninsured patients who returned post-ACA (July 2014 to December 2015). RESULTS: The total number of ED visits in Maryland decreased by 36,531 (-1.2%) between the 6 quarters pre-ACA and the 6 quarters post-ACA. Medicaid-covered ED visits increased from 23.3% to 28.9% (159,004 additional visits), whereas uninsured patient visits decreased from 16.3% to 10.4% (181,607 fewer visits). Coverage by other insurance types remained largely stable between periods. We found no significant relationship between Medicaid expansion and changes in ED volume by hospital. For patients uninsured pre-ACA who returned post-ACA, the adjusted visits per person during 6 quarters was 2.38 (95% confidence interval 2.35 to 2.40) for those newly enrolled in Medicaid post-ACA compared with 1.66 (95% confidence interval 1.64 to 1.68) for those remaining uninsured. CONCLUSION: There was a substantial increase in patients covered by Medicaid in the post-ACA period, but this did not significantly affect total ED volume. Returning patients newly enrolled in Medicaid visited the ED more than their uninsured counterparts; however, this cohort accounted for only a small percentage of total ED visits in Maryland.

Reliability and validity of pediatric triage tools evaluated in Low resource settings: a systematic review.

BACKGROUND: Despite the high burden of pediatric mortality from preventable conditions in low and middle income countries and the existence of multiple tools to prioritize critically ill children in low-resource settings, no analysis exists of the reliability and validity of these tools in identifying critically ill children in these scenarios. METHODS: The authors performed a systematic search of the peer-reviewed literature published, for studies pertaining to for triage and IMCI in low and middle-income countries in English language, from January 01, 2000 to October 22, 2013. An updated literature search was performed on on July 1, 2015. The databases searched included the Cochrane Library, EMBASE, Medline, PubMed and Web of Science. Only studies that presented data on the reliability and validity evaluations of triage tool were included in this review. Two independent reviewers utilized a data abstraction tool to collect data on demographics, triage tool components and the reliability and validity data and summary findings for each triage tool assessed. RESULTS: Of the 4,717 studies searched, seven studies evaluating triage tools and 10 studies evaluating IMCI were included. There were wide varieties in method for assessing reliability and validity, with different settings, outcome metrics and statistical methods. CONCLUSIONS: Studies evaluating triage tools for pediatric patients in low and middle income countries are scarce. Furthermore the methodology utilized in the conduct of these studies varies greatly and does not allow for the comparison of tools across study sites.

Clinical metrics in emergency medicine: the shock index and the probability of hospital admission and inpatient mortality.

STUDY OBJECTIVES: The shock index (SI), defined as the ratio of HR to systolic BP, has been studied as an alternative prognostic tool to traditional vital signs in specific disease states and subgroups of patients. However, literature regarding its utility in the general ED population is lacking. Our main objective was to determine the probability of admission and inpatient mortality based on the first measured SI at initial presentation in the general adult ED population in our tertiary care centre. METHODS: A retrospective chart review of all adult patients (≥18 years old) presenting to the ED at our tertiary care centre over a 12-month period was conducted. Likelihood ratios (LRs) were calculated in order to determine the optimal SI cut-off for predicting hospital admission and inpatient mortality. RESULTS: We reviewed 58 336 ED patient encounters occurring between 1 October 2012 and 30 September 2013. SI >1.2 was associated with a large increase in the likelihood of hospital admission, with a positive LR (+LR) of 11.69 (95% CI 9.50 to 14.39) and a moderate increase in the likelihood of inpatient mortality with a +LR of 5.82 (95% CI 4.31 to 7.85). SI >0.7 and >0.9, the traditional 'normal' cut-offs cited in the literature, were only associated with minimal to small increases in the likelihood of admission and inpatient mortality. CONCLUSIONS: In our single-centre study, the initial SI recorded in the ED shows promise as a clinical metric in the general adult ED population, increasing the probability of both hospital admission and inpatient mortality, specifically at a threshold of SI >1.2.

Evaluation of the Centers for Disease Control and Prevention Recommendations for Hepatitis C Virus Testing in an Urban Emergency Department.

BACKGROUND: The Centers for Disease Control and Prevention (CDC) recommends 1-time hepatitis C virus (HCV) testing in the 1945-1965 birth cohort, in addition to targeted risk-based testing. Emergency departments (EDs) are key venues for HCV testing because of the population served and success in HIV screening. We determined the burden of undocumented HCV infection in our ED, providing guidance for implementation of ED-based HCV testing. METHODS: An 8-week seroprevalence study was conducted in an urban ED in 2013. All patients with excess blood collected for clinical purposes were included. Demographic and clinical information including documented HCV infection was obtained from electronic medical records. HCV antibody testing was performed on excess samples. RESULTS: Of 4713 patients, 652 (13.8%) were HCV antibody positive. Of these, 204 (31.3%) had undocumented HCV infection. Among patients with undocumented infections, 99 (48.5%) would have been diagnosed based on birth cohort testing, and an additional 54 (26.5%) would be identified by risk-based testing. If our ED adhered to the CDC guidelines, 51 (25.0%) patients with undocumented HCV would not have been tested. Given an estimated 7727 unique ED patients with HCV infection in a 1-year period, birth cohort plus risk-based testing would identify 1815 undocumented infections, and universal testing would identify additional 526 HCV-infected persons. CONCLUSIONS: Birth cohort-based testing would augment identification of undocumented HCV infections in this ED 2-fold, relative to risk-based testing only. However, our data demonstrate that one-quarter of infections would remain undiagnosed if current CDC birth cohort recommendations were employed, suggesting that in high-risk urban ED settings a practice of universal 1-time testing might be more effective.

Evaluation of hidden HIV infections in an urban ED with a rapid HIV screening program.

BACKGROUND: To investigate the prevalence of undiagnosed HIV infections in an emergency department (ED) with an established screening program. METHODS: Evaluation of the prevalence and risk factors for HIV from an 8-week (June 24, 2007-August 18, 2007) identity-unlinked HIV serosurvey, conducted at the same time as an ongoing opt-in rapid oral-fluid HIV screening program. Testing facilitators offering 24/7 bedside rapid testing to patients aged 18 to 64 years, with concordant collection of excess sera collected as part of routine clinical procedures. Known HIV positivity was determined by (1) medical record review or self-report from the screening program and/or (2) presence of antiretrovirals in serum specimens. RESULTS: Among 3207 patients, 1165 (36.3%) patients were offered an HIV test. Among those offered, 567 (48.7%) consented to testing. Concordance identity-unlinked study revealed that the prevalence of undiagnosed infections was as follows: 2.3% in all patients, 1.0% in those offered testing vs 3.0% in those not offered testing (P < .001); and 1.3% in those who declined testing compared with 0.4% in those who were tested (P = .077). Higher median viral loads were observed in those not offered testing (14255 copies/mL; interquartile range, 1147-64354) vs those offered testing (1865 copies/mL; interquartile range, undetectable-21786), but the difference was not statistically significant. CONCLUSIONS: High undiagnosed HIV prevalence was observed in ED patients who were not offered HIV testing and those who declined testing, compared with those who were tested. This indicates that even with an intensive facilitator-based rapid HIV screening model, significant missed opportunities remain with regard to identifying undiagnosed infections in the ED.

Emergency Department Evaluation of Traumatic Brain Injury in the United States, 2009-2010.

OBJECTIVE: To determine the dimensions of traumatic brain injury (TBI) evaluation in US emergency department (EDs) to inform potential application of novel diagnostic tests. SETTING: US EDs. PARTICIPANTS: National Hospital Ambulatory Medical Care Survey of ED visits in 2009 and 2010 where TBI was evaluated (1) and diagnosed either clinically or (2) with head computed tomographic (CT) scans. DESIGN: Retrospective cross-sectional. RESULTS: TBI was evaluated during 4.8 (95% confidence interval [CI], 4.2-5.4) million visits per year; and head CT scan was performed in 82% of TBI evaluations (3.9 [95% CI, 3.4-4.4] million visits per year). TBI was diagnosed in 52% of evaluations (2.5 [95% CI, 2.1-2.8] million visits per year). Among those who received head CT scans, 9% had CT evidence of traumatic abnormalities. Among patients evaluated for TBI who had a Glasgow Coma Scale score recorded, 94.5% were classified as having mild TBI, 2.1% as moderate TBI, and 3.5% as severe TBI. Among patients with International Classification of Diseases, Ninth Revision, Clinical Modification, codes permitting the calculation of head Abbreviated Injury Scale scores 9.0%, 85.0%, 2.5%, 3.2%, 0.3%, and 0% had head Abbreviated Injury Scale scores of 1, 2, 3, 4, 5, and 6, respectively. Of patients evaluated for TBI, 31% had other head/face/neck injuries, 10% had spine and back injuries, 7% had torso injuries, and 14% had extremity injuries. CONCLUSION: The ED is the main gateway to medical care for millions of patients evaluated for TBI each year. Novel diagnostic tests are needed to improve ED diagnosis and management of TBI.

HIV Care Continuum for HIV-Infected Emergency Department Patients in an Inner-City Academic Emergency Department.

STUDY OBJECTIVE: The recently released HIV Care Continuum Initiative is a cornerstone of the National AIDS Strategy and a model for improving care for those living with HIV. To our knowledge, there are no studies exploring the entirety of the HIV Care Continuum for patients in the emergency department (ED). We determine gaps in the HIV Care Continuum to identify potential opportunities for improved care for HIV-infected ED patients. METHODS: A mixed-methods approach was used in 1 inner-city ED in 2007. Data elements were derived from an identity-unlinked HIV seroprevalence study, an ongoing nontargeted HIV screening program, and a structured survey of known HIV-positive ED patients. RESULTS: Identity-unlinked testing of 3,417 unique ED patients found that 265 (7.8%) were HIV positive. Of patients testing HIV positive, 73% had received a previous diagnosis (based on self-report, chart review, or presence of antiretrovirals in serum), but only 61% were recognized by the clinician as being HIV infected (based on self-report or chart review). Of patients testing positive, 43% were linked to care, 39% were retained in care, 27% were receiving antiretrovirals, 26% were aware of their receiving antiretroviral treatment, 22% were virally suppressed, and only 9% were self-aware of their viral suppression. CONCLUSION: To our knowledge, this study is the first to quantify gaps in HIV care for an ED patient population, with the HIV Care Continuum as a framework. Our findings identified distinct phases (ie, testing, provider awareness of HIV diagnosis, and linkage to care) in which the greatest opportunities for intervention exist, if appropriate resources were allocated. This schema could serve as a model for other indolent treatable diseases frequently observed in EDs, where continuity of care is critical.

Disaster Metrics: Evaluation of de Boer's Disaster Severity Scale (DSS) Applied to Earthquakes.

INTRODUCTION: Quantitative measurement of the medical severity following multiple-casualty events (MCEs) is an important goal in disaster medicine. In 1990, de Boer proposed a 13-point, 7-parameter scale called the Disaster Severity Scale (DSS). Parameters include cause, duration, radius, number of casualties, nature of injuries, rescue time, and effect on surrounding community. Hypothesis This study aimed to examine the reliability and dimensionality (number of salient themes) of de Boer's DSS scale through its application to 144 discrete earthquake events. METHODS: A search for earthquake events was conducted via National Oceanic and Atmospheric Administration (NOAA) and US Geological Survey (USGS) databases. Two experts in the field of disaster medicine independently reviewed and assigned scores for parameters that had no data readily available (nature of injuries, rescue time, and effect on surrounding community), and differences were reconciled via consensus. Principle Component Analysis was performed using SPSS Statistics for Windows Version 22.0 (IBM Corp; Armonk, New York USA) to evaluate the reliability and dimensionality of the DSS. RESULTS: A total of 144 individual earthquakes from 2003 through 2013 were identified and scored. Of 13 points possible, the mean score was 6.04, the mode = 5, minimum = 4, maximum = 11, and standard deviation = 2.23. Three parameters in the DSS had zero variance (ie, the parameter received the same score in all 144 earthquakes). Because of the zero contribution to variance, these three parameters (cause, duration, and radius) were removed to run the statistical analysis. Cronbach's alpha score, a coefficient of internal consistency, for the remaining four parameters was found to be robust at 0.89. Principle Component Analysis showed uni-dimensional characteristics with only one component having an eigenvalue greater than one at 3.17. The 4-parameter DSS, however, suffered from restriction of scoring range on both parameter and scale levels. CONCLUSION: Jan de Boer's DSS in its 7-parameter format fails to hold statistically in a dataset of 144 earthquakes subjected to analysis. A modified 4-parameter scale was found to quantitatively assess medical severity more directly, but remains flawed due to range restriction on both individual parameter and scale levels. Further research is needed in the field of disaster metrics to develop a scale that is reliable in its complete set of parameters, capable of better fine discrimination, and uni-dimensional in measurement of the medical severity of MCEs.

T32 programs in emergency medicine: A report from the ACEP-SAEM Federal Research Funding Workgroup.

Advancing care in Emergency Medicine (EM) requires the development of well-trained researchers, but our specialty has lower amounts of research funding compared to similar medical fields. Increasing the number of pathways available for research training supports the growth of new investigators. To address the need for more EM researchers, the Society of Academic Emergency Medicine and the American College of Emergency Physicians convened a Federal Research Funding Workgroup. Here, we report the workgroup recommendations regarding the creation of Research Training Fellowships using the T32 grant structure sponsored by the National Institutes of Health. After reviewing the history of NIH-grant supported research fellowships in EM, we outline the rationale and describe the core components of T32-supported research fellowships, including program design, fellow evaluation, and recruitment considerations.

National needs assessment of emergency medicine faculty regarding scholarly activity practices and support.

Objectives: We aimed to assess the attitudes and perceptions of scholarly activity (SA) practices among emergency medicine (EM) physicians who are engaged in training residents. This study examined the belief and need for modern-day SA, potential barriers, and department resources provided. Methods: We conducted a descriptive cross-sectional survey study of EM physicians across the United States identified from the American College of Emergency Physicians and American College of Osteopathic Physicians directories. The survey consisted of 18 items regarding demographics, attitude toward SA, department support, and questions regarding residency programs. Results: A total of 660 survey recipients completed the survey out of a possible pool of 4296 individuals (15% response rate), of which 530 (80%) indicated they were core faculty. Of core faculty, 428 (80.8%) were part of an allopathic program, whereas 102 (19.2%) were part of an osteopathic program. Department support was provided for protected time (385; 58.3%), research staff (346; 52.4%), Institutional Review Board preparation (240; 36.4%), and biostatistics (314; 47.6%). Of all the institutional roles, the largest percentage (82/125, 65.6%) of chair/vice chair/associate chairs strongly agreed or agreed (score of 5 or 4 of 5) with the statement, "Overall, I am satisfied with the scholarly support provided by my department." There was no difference in agreement with this statement between respondents in an allopathic versus osteopathic program (210/428, 49.1% allopathic; 45/102, 44.1% osteopathic). Conclusion: There is a need for increased departmental support for SA. To optimally implement the Accreditation Council for Graduate Medical Education (ACGME) SA requirements into strategy and action, the ACGME should consider providing EM residency programs with an outline of best SA practices to foster a uniform consensus across academic institutions.
