RESUMO
Objectives: This study aims to better understand the perspectives of emergency medicine physicians' on the role that state-mandated, topic-specific continuing medical education (CME) plays in addressing knowledge gaps, its relevance to current emergency practice, its reported burden and costs of CME activities to emergency physicians, and its perceived improvement in patient care. Methods: A cross-sectional survey was designed by the Coalition of Board-Certified Emergency Physicians (COBCEP) and distributed in February 2023 to all American Board of Emergency Medicine (ABEM)-certified physicians. Statistical tests of significance (Pearson's chi-square and Fisher's exact test) assessed the cost and time spent on CME as well as the perceived value placed on CME by ABEM-certified physicians to improve patient care. Data were summarized using descriptive statistics. Results: There were 5562 (13.0%) responses from the 43656 physicians who received the survey-5506 responses were included for analysis. Over half of the physicians (53.0%) had more than 15 years of post-residency practice experience. Most physicians (57.3%) spent less than $5,000 per year on obtaining CME. Most physicians practicing in states with state-mandated, topic-specific CME requirements believed that participation in ABEM continuing certification could be used to reduce the need for state-mandated, topic-specific CME requirements (83.6%) and state-mandated, topic-specific requirements were believed to be unlikely to improve patient care (70.8%). Conclusions: Although well-intended, state CME requirements may lack relevancy and can, at times, place an undue burden on emergency physicians. Tailoring CME requirements to increase relevance to their patient populations and reduce barriers to completing CME could enhance knowledge translation and improve patient outcomes.
RESUMO
BACKGROUND: Updated 2021 hepatitis C virus (HCV) treatment guidelines no longer recommend fibrosis staging for treatment-naïve patients without cirrhosis; however, numerous US state Medicaid plans continue to restrict initiation of HCV therapy by fibrosis stage. The study objective was to determine whether delays from HCV diagnosis to fibrosis staging impact the likelihood of initiating/completing HCV treatment and achieving sustained virologic response (SVR). METHODS: A retrospective cohort study was performed among patients diagnosed with chronic HCV by an urban US emergency department who subsequently underwent fibrosis staging. Time elapsed from HCV diagnosis to hepatic fibrosis staging was evaluated on the likelihood of treatment initiation, treatment completion and SVR. RESULTS: Among fibrosis staging modalities, hepatic ultrasounds occurred more quickly following HCV diagnosis (3.5 months, IQR = 12.4 months), compared to FibroSure (8.5 months, IQR = 20.4 months) and FibroScan (9.9 months, IQR = 18.0 months) (p<.001). Each six-month delay in fibrosis staging decreased the likelihood of initiating treatment by 5% (adjusted relative risk (aRR)=0.95; 95% confidence interval (CI)=0.91-0.998; p=.04) and the likelihood of SVR by 7% (aRR = 0.93; 95% CI = 0.87-0.995; p=.04) after adjusting for insurance, race/ethnicity and history of HIV testing. CONCLUSIONS: Delays in hepatitis fibrosis staging were significantly associated with decreased likelihood of HCV treatment initiation and SVR.

The hepatitis C virus (HCV) treatment landscape is shifting given the advent of direct-acting antivirals and a global call to action by the World Health Organization. Eliminating HCV is now an issue of healthcare delivery. Treatment is limited by the complexity of the HCV care continuum, expensive therapy and competing health burdens experienced by an underserved HCV population. The objective of this literature review was to assess strategies to improve retention in HCV care, with particular focus on those implemented in the United States. We identified barriers in HCV care retention and propose solutions to increase HCV treatment delivery. The following recommendations are herein described: improving the cohesion of health services through localized care and integrated case management, expanding the supply of non-specialist HCV treatment providers, leveraging patient navigators and care coordinators, improving adherence through directly observed therapy and reducing cost barriers through value-based payment and pharmaceutical subscription models.

OBJECTIVES: Emergency department (ED) hepatitis C virus (HCV) screening programs are proliferating, and it is unknown whether EDs are more effective than traditional community screening at promoting HCV follow-up care. The objective of this study was to investigate whether patients screened HCV seropositive (HCV+) in the ED are linked to care and retained in treatment more successfully than patients screened HCV+ in the community. METHODS: A retrospective cohort study was performed including patients screened HCV+ at twelve screening facilities in New Orleans, LA from March 1, 2015 to July 31, 2017. Treatment outcomes, including retention and time to follow-up care, were assessed using the HCV continuum of care model. RESULTS: ED patients (n = 3008) were significantly more likely to achieve RNA confirmation (aRR = 1.91, 95% CI = 1.54-2.37), initiate HCV therapy (aRR = 2.23 [1.76-2.83]), complete HCV therapy (aRR = 1.77 [1.40-2.24]), and achieve HCV functional cure (aRR = 2.80 [1.09-7.23]) compared to community-screened patients (n = 322). ED screening was associated with decreased likelihood of fibrosis staging (aRR = 0.65 [0.51-0.82]) and no difference in linkage to specialty care (aRR = 1.03 [0.69-1.53]). In time to follow up, RNA confirmation occurred at faster rates in the ED (aHR = 2.26 [1.86-2.72]), although these patients completed fibrosis staging at slower rates (aHR = 0.49 [0.38-0.63]) than community patients. CONCLUSIONS: Compared to community screening, HCV screening in the ED was associated with higher rates of disease confirmation, treatment initiation/completion, and cure. Our findings provide new evidence that EDs may be the most effective setting to screen patients for HCV to promote follow-up care.

The coronavirus disease 2019 crisis has forced the world to integrate telemedicine into health delivery systems in an unprecedented way. To deliver essential care, lawmakers, physicians, patients, payers, and health systems have all adopted telemedicine and redesigned delivery processes with accelerated speed and coordination in a fragmented way without a long-term vision or uniformed standards. There is an opportunity to learn from the experiences gained by this pandemic to help shape a better health-care system that standardizes telemedicine to optimize the overall efficiency of remote health-care delivery. This collaboration focuses on four pillars of telemedicine that will serve as a framework to enable a uniformed, standardized process that allows for remote data capture and quality, aiming to improve ongoing management outside the hospital. In this collaboration, we recommend learning from this experience by proposing a telemedicine framework built on the following four pillars-patient safety and confidentiality; metrics, analytics, and reform; recording of audio-visual data as a health record; and reimbursement and accountability.
RESUMO
INTRODUCTION: Firearm injury and death is increasingly prevalent in the United States. Emergency physicians (EP) may have a unique role in firearm injury prevention. The aim of this study was to describe EPs' beliefs, attitudes, practices, and barriers to identifying risk of and counseling on firearm injury prevention with patients. A secondary aim was assessment of perceived personal vulnerability to firearm injury while working in the emergency department (ED). METHODS: We conducted a cross-sectional survey of a national convenience sample of EPs, using questions adapted from the American College of Surgeons' Committee on Trauma 2017 survey of surgeons. Descriptive statistics and chi-square tests were calculated as appropriate. RESULTS: A total of 1901 surveys were completed by EPs from across the United States. Among respondents, 42.9% had a firearm at home, and 56.0% had received firearm safety training. Although 51.4% of physicians in our sample were comfortable discussing firearm access with their high-risk patients, more than 70% agreed or strongly agreed that they wanted training on procedures to follow when they identify that a patient is at high risk of firearm injury. Respondents reported a variety of current practices regarding screening, counseling, and resource use for patients at high risk of firearm injury; the highest awareness and self-reported screening and counseling on firearm safety was with patients with suicidal ideation. Although 92.3% of EPs reported concerns about personal safety associated with firearms in the ED, 48.1% reported that there was either no protocol for dealing with a firearm in the ED, or if there was a protocol, they were not aware of it. Differences in demographics, knowledge, attitudes, and behavior were observed between respondents with a firearm in the home, and those without a firearm in the home. CONCLUSIONS: Among respondents to this national survey of a convenience sample of EPs, approximately 40% had a firearm at home. The majority reported wanting increased education and training to identify and counsel ED patients at high risk for firearm injury. Improved guidance on personal safety regarding firearms in the ED is also needed.

BACKGROUND: Despite identified inequities and disparities in lesbian, gay, bisexual, transgender, queer, and questioning (LGBTQ+) health, past studies have shown little or no education at the medical school or residency level for emergency physicians. With increased focus on health inequities and disparities, we sought to reexamine the status of sexual and gender minority health education in U.S. emergency medicine (EM) residencies. OBJECTIVES: Our primary objective was to determine how many EM residencies offer education on LGBTQ+ health. Secondary objectives included the number of actual versus preferred hours of LGBTQ+ training, identification of barriers to providing education, and correlation of education with program demographics. Finally, we compared our current data with past results of our 2013 study. METHODS: The initial survey that sought to examine LGBTQ+ training in 2013 was used and sent in 2020 via email to EM programs accredited by the American Council for Graduate Medical Education who had at least one full class of residents in 2019. Reminder emails and a reminder post on the Council of Residency Directors in Emergency Medicine listserv were used to increase participation. RESULTS: A total of 229 programs were eligible, with a 49.3% response rate (113/229). The majority (75%) offered education content on LGBTQ+ health, for a median (IQR) of 2 (1-3) hours and a range of 0 to 22 hours. Respondents preferred more hours of education than offered (median desired hours = 4, IQR = 2-5 hours; p < 0.001). The largest barrier identified was lack of time in curriculum (63%). The majority of programs had known LGBTQ+ faculty and residents. Inclusion and amount of education hours positively correlated with presence of LGBTQ+ faculty or residents; university- and county-based programs were more likely to deliver education content than private groups (p = 0.03). Awareness of known LGBTQ+ residents but not faculty differed by region, but there was no significant difference in actual or preferred content by region. CONCLUSION: The majority of respondents offer education in sexual and gender minority health, although there remains a gap between actual and preferred hours. This is a notable increase from 26% of responding programs providing education in 2013. Several barriers still exist, and the content, impact, and completeness of education remain areas for further study.
RESUMO
The idea of doing a research or scholarly project can be very daunting, however, the satisfaction of seeing a project to its completion is very rewarding. In this article, we provide medical students with guidance on whether they should take on a research or scholarly project during medical school, and how to get started, publish, and then present their project. We also highlight how such a project can benefit an applicant applying for residency training.

BACKGROUND: The benefits of a diverse workforce in medicine have been previously described. While the population of the United States has become increasingly diverse, this has not occurred in the physician workforce. In academic medicine, underrepresented in medicine (URiM) faculty are less likely to be promoted or retained in academic institutions. Studies suggest that mentorship and engagement increase the likelihood of development, retention, and promotion. However, it is not clear what form of mentorship creates these changes. The Academy for Diversity and Inclusion in Emergency Medicine (ADIEM), an academy within the Society for Academic Emergency Medicine, is a group focused on advancing diversity and inclusion as well as promoting the development of its URiM students, residents, and faculty. The Academy serves many of the functions of a mentoring program. We assessed whether active involvement in ADIEM led to increased publications, promotion, or leadership advancement in the areas of diversity, equity, and inclusion. METHODS: We performed a survey of ADIEM members to determine if career development and productivity, defined as written scholarly products, presentations, and mentorship in the area of diversity, equity, and inclusion was enhanced by the establishment of the academy. To determine whether there were significant changes in academic accomplishments after the formation of ADIEM, two groups, ADIEM leaders and ADIEM nonleader members, were examined. RESULTS: Thirteen ADIEM leaders and 14 ADIEM nonleader members completed the survey. Academic productivity in the area of diversity, equity, and inclusion increased significantly among ADIEM leaders when compared to ADIEM nonleader members after the founding of ADIEM. In particular, in the ADIEM leader group, there were significant increases in manuscript publications (1.31 ± 1.6 to 5.5 ± 7.96, p = 0.12), didactic presentations (3.85 ± 7.36 to 23.46 ± 44.52, p < 0.01), grand rounds presentations (0.83 ± 1.75 to 8.6 ± 10.71, p < 0.05), and student/resident mentees (6.46 ± 9.36 to 25 ± 30.41, p = 0.02). CONCLUSION: The formation of a specialized academy within a national medical society has advanced academic accomplishments in diversity, equity, and inclusion in emergency medicine among ADIEM leadership. Involvement of URiM and lesbian, gay, bisexual, and transgender faculty in the academy fostered faculty development, mentoring, and educational scholarship.
RESUMO
Background: A 2006 study of emergency medicine (EM) patients found male physicians were more often recognized as doctors that were female physicians. We sought to identify gender awareness of EM physicians and nurses by patients to see whether there has been a reduction in gender bias during the past 12 years. Materials and Methods: Before emergency department (ED) discharge or hospital admission, a convenience sample of 150 patients in an urban academic ED was anonymously surveyed to determine their awareness of the role of the health personnel involved in their care. Results: Our patients recognized male attending physicians as physicians 75.7% of the time and female attending physicians as physicians 58.1% of the time (p < 0.01). No differences were observed for resident physicians. Patients recognized male nurses as nurses 77.1% of the time, and female nurses as nurses 91.1% of the time (p < 0.01). Conclusions: These data indicate that patients continue to exhibit gender bias in the recognition of lead physicians and nurses.

BACKGROUND: Transorbital ultrasound was used to diagnose acute optic neuritis (AON) at bedside in an emergency department (ED). CASE REPORT: A 59-year-old female patient presented to an ED after 7 days of progressive unilateral visual loss while she was receiving outpatient treatment for relapsing-remitting multiple sclerosis. Transorbital ultrasound revealed a disparity between the optic nerve sheath diameters of the affected and nonaffected eyes and striking optic nerve edema in the affected eye. These findings led to a diagnosis of AON and early definitive treatment. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Given an absence of reliable diagnostic criteria for AON, comorbidity with multiple sclerosis, and limitations inherent to magnetic resonance imaging, transorbital sonography may facilitate diagnosis of this condition in emergent presentations.

BACKGROUND: Although lesbian, gay, bisexual, and transgender (LGBT) patients are ubiquitous in emergency medicine (EM), little education is provided to EM physicians on LGBT health care needs and disparities. There is also limited information on EM physician behavior, comfort, and attitudes toward LGBT patients. The objective of this study was to assess EM residents behavior, comfort, and attitudes in LGBT health. METHODS: An anonymous survey link was sent to EM programs via the Council of Residency Director listserv. The primary outcome of the 24-item descriptive survey was the self-reported comfort levels and self-reported practice in LGBT health care. Secondary outcomes included individual comfort toward LGBT colleagues and patients who are LGBT, and the frequency of colleagues making discriminatory statements toward LGBT patients and staff in the emergency department setting. Associations between personal and program demographics and survey responses were also examined. RESULTS: There were 319 responses The majority of respondents were male (63.4%), Caucasian (69.1%), and heterosexual (92.4%). A sizeable minority of respondents felt histories and physical examinations were more challenging for lesbian, gay, or bisexual patients (24.6%) and more so for transgender patients (42.6%). Most residents do not ask patients to identify sexual orientation when presenting with abdominal or genital complaints (63%). Discriminatory LGBT comments were reported from both fellow residents (16.6%) and faculty (10%). A total of 2.5% of respondents were uncomfortable with other LGBT physicians, and 6% did not agree that LGBT patients deserve the same quality care as others. CONCLUSION: A number of residents find caring for LGBT patients more challenging than heterosexual patients. Even with professed comfort with LGBT health care, most residents report taking incomplete sexual histories that may affect patient care. Attitudes toward LGBT patients are mainly, but not completely, positive in this cohort.
RESUMO
STUDY OBJECTIVE: Newer combination HIV antigen-antibody tests allow detection of HIV sooner after infection than previous antibody-only immunoassays because, in addition to HIV-1 and -2 antibodies, they detect the HIV-1 p24 antigen, which appears before antibodies develop. We determine the yield of screening with HIV antigen-antibody tests and clinical presentations for new diagnoses of acute and established HIV infection across US emergency departments (EDs). METHODS: This was a retrospective study of 9 EDs in 6 cities with HIV screening programs that integrated laboratory-based antigen-antibody tests between November 1, 2012, and December 31, 2015. Unique patients with newly diagnosed HIV infection were identified and classified as having either acute HIV infection or established HIV infection. Acute HIV infection was defined as a repeatedly reactive antigen-antibody test result, a negative HIV-1/HIV-2 antibody differentiation assay, or Western blot result, but detectable HIV ribonucleic acid (RNA); established HIV infection was defined as a repeatedly reactive antigen-antibody test result and a positive HIV-1/HIV-2 antibody differentiation assay or Western blot result. The primary outcomes were the number of new HIV diagnoses and proportion of patients with laboratory-defined acute HIV infection. Secondary outcomes compared reason for visit and the clinical presentation of acute HIV infection. RESULTS: In total, 214,524 patients were screened for HIV and 839 (0.4%) received a new diagnosis, of which 122 (14.5%) were acute HIV infection and 717 (85.5%) were established HIV infection. Compared with patients with established HIV infection, those with acute HIV infection were younger, had higher RNA and CD4 counts, and were more likely to have viral syndrome (41.8% versus 6.5%) or fever (14.3% versus 3.4%) as their reason for visit. Most patients with acute HIV infection displayed symptoms attributable to acute infection (median symptom count 5 [interquartile range 3 to 6]), with fever often accompanied by greater than or equal to 3 other symptoms (60.7%). CONCLUSION: ED screening using antigen-antibody tests identifies previously undiagnosed HIV infection at proportions that exceed the Centers for Disease Control and Prevention's screening threshold, with the added yield of identifying acute HIV infection in approximately 15% of patients with a new diagnosis. Patients with acute HIV infection often seek ED care for symptoms related to seroconversion.

RATIONALE: Neurogenic hypertension is characterized by an increase in sympathetic activity and often resistance to drug treatments. We previously reported that it is also associated with a reduction of angiotensin-converting enzyme type 2 (ACE2) and an increase in a disintegrin and metalloprotease 17 (ADAM17) activity in experimental hypertension. In addition, while multiple cells within the central nervous system have been involved in the development of neurogenic hypertension, the contribution of ADAM17 has not been investigated. OBJECTIVE: To assess the clinical relevance of this ADAM17-mediated ACE2 shedding in hypertensive patients and further identify the cell types and signaling pathways involved in this process. METHODS AND RESULTS: Using a mass spectrometry-based assay, we identified ACE2 as the main enzyme converting angiotensin II into angiotensin-(1-7) in human cerebrospinal fluid. We also observed an increase in ACE2 activity in the cerebrospinal fluid of hypertensive patients, which was correlated with systolic blood pressure. Moreover, the increased level of tumor necrosis factor-α in those cerebrospinal fluid samples confirmed that ADAM17 was upregulated in the brain of hypertensive patients. To further assess the interaction between brain renin-angiotensin system and ADAM17, we generated mice lacking angiotensin II type 1 receptors specifically on neurons. Our data reveal that despite expression on astrocytes and other cells types in the brain, ADAM17 upregulation during deoxycorticosterone acetate-salt hypertension occurs selectively on neurons, and neuronal angiotensin II type 1 receptors are indispensable to this process. Mechanistically, reactive oxygen species and extracellular signal-regulated kinase were found to mediate ADAM17 activation. CONCLUSIONS: Our data demonstrate that angiotensin II type 1 receptors promote ADAM17-mediated ACE2 shedding in the brain of hypertensive patients, leading to a loss in compensatory activity during neurogenic hypertension.

Admission of patients who have do not resuscitate (DNR) status to an intensive care unit (ICU) is potentially a misallocation of limited resources to patients who may neither need nor want intensive care. Yet, patients who have DNR status are often admitted to the ICU. This is a retrospective review of patients who had a valid DNR status at the time that they were admitted to an ICU in a single hospital over an eighteen-month period. Thirty-five patients met the criteria for inclusion in the study. The primary reasons for admission to the ICU were respiratory distress (54.2%) and sepsis (45.7%). Sixteen (45.7%) of the patients died, compared to a 5.4% mortality rate for all patients admitted to our ICU during this period (p < 0.001). APACHE II score was a significant predictor of mortality (18.5 ± 1.3 alive and 23.4 ± 1.4 dead; p = 0.038). Of the 19 patients discharged alive, 9 were discharged home, 5 to hospice, and 4 to a post-acute care facility. Conclusions. Patients who have DNR status and are admitted to the ICU have a higher mortality than other ICU patients. Those who survive have a high likelihood of being discharged to hospice or a post-acute care facility. The value of intensive intervention for these patients is not supported by these results. Only a minority of patients were seen by palliative care and chaplain teams, services which the literature supports as valuable for DNR patients. Our study supports the need for less expensive and less intensive but more appropriate resources for patients and families who have chosen DNR status.
RESUMO
BACKGROUND: The United States health care system remains far from implementing the Centers for Disease Control and Prevention's recommendation of routine human immunodeficiency virus (HIV) screening as part of health care for adults. Although consensus for the importance of screening has grown, innovations in implementing routine screening are still lacking. HIV on the Frontlines of Communities in the United States (FOCUS) was launched in 2010 to provide an environment for testing innovative approaches to routine HIV screening and linkage to care. OBJECTIVE: The strategy of the FOCUS program was to develop models that maximize the use of information systems, fully integrate HIV screening into clinical practice, transform basic perceptions about routine HIV screening, and capitalize on emerging technologies in health care settings and laboratories. METHODS: In 10 of the most highly impacted cities, the FOCUS program supports 153 partnerships to increase routine HIV screening in clinical and community settings. RESULTS: From program launch in 2010 through October 2013, the partnerships have resulted in a total of 799,573 HIV tests and 0.68% (5425/799,573) tested positive. CONCLUSIONS: The FOCUS program is a unique model that will identify best practices for HIV screening and linkage to care.
