Do Gender and Race Make a Difference in Acute Coronary Syndrome Pretest Probabilities in the Emergency Department?

Healthcare providers' psychological investment in clinical recommendations: Investigating the role of implicit racial attitudes

Racial disparities in clinical recommendations can result in racial disparities in health. While healthcare providers' implicit racial attitudes (affective component of bias) are theorized to be one major factor contributing to racial disparities in clinical recommendations, empirical evidence to support the link is lacking. This study aimed to bridge this gap by moving beyond the standard approach of operationalizing the quality of clinical recommendations as a guideline-consistent vs. -inconsistent dichotomy. The present secondary study examined the role of provider implicit racial attitudes in the quality of clinical recommendations, operationalized as behaviors reflecting providers' psychological investment in patient care (i.e., number of words used to describe clinical recommendations, and number of treatment options recommended). Two-hundred-and-ten White medical trainees reviewed a clinical vignette of either a White or Black male patient and provided clinical recommendations. Their implicit racial attitudes were evaluated using the Implicit Association Test. Participants with more biased implicit racial attitudes (i.e., stronger implicit preference for White vs. Black individuals) used fewer words to describe their clinical recommendations and provided fewer clinical recommendations for the Black (vs. White) patient, while there were no significant differences between Black and White patients among participants with less biased implicit racial attitudes. These results illustrate the insidious impact of implicit racial attitudes in healthcare provision and underscore the need for researchers to consider the complex, nuanced ways in which provider implicit racial attitudes might manifest in clinical decision-making.

Impacts of high sensitivity troponin T reporting on care and outcomes in clinical practice: Interactions between low troponin concentrations and participant sex within two randomized clinical trials

BACKGROUND

The impacts of high sensitivity cardiac troponin (hs-cTn) reporting on downstream interventions amongst suspected acute coronary syndrome (ACS) in the emergency department (ED), especially amongst those with newly identified hs-cTn elevations and in consideration of well-established sex-related disparities, has not been critically evaluated to date. This investigation explores the impact of hs-cTnT reporting on care and outcomes, particularly by participant sex.

METHODS

Two similarly ED-based randomized controlled trials conducted between July 2011 to March 2013 (n = 1988) and August 2015 to April 2019 (n = 3378) were comparatively evaluated. Clinical outcomes were adjudicated to the Fourth Universal Definition of MI. Changes in practice were assessed at 30 days, and death or MI were explored to 12 months.

RESULTS

The HS-Troponin study demonstrated no difference in death or MI with unmasking amongst those with hs-cTnT <30 ng/L, whereas the RAPID TnT study demonstrated a significantly higher rate. In RAPID TnT, there was significant increase in death or MI associated with unmasking for females with hs-cTnT <30 ng/L (masked: 11[1.5%], unmasked: 25[3.4%],HR: 2.27,95%C.I.:1.87-2.77,P < 0.001). Less cardiac stress testing with unmasking amongst those <30 ng/L was observed in males in both studies, which was significant in RAPID TnT (masked: 92[12.0%], unmasked: 55[7.0%], P = 0.008). In RAPID TnT, significantly higher rates of angiography in males were observed with unmasking, with no such changes amongst females <30 ng/L (masked: 28[3.7%], unmasked: 51[6.5%],P = 0.01).

CONCLUSION

Compared with males, there were no evident impacts on downstream practices for females with unmasking in RAPID TnT, likely representing missed opportunities to reduce late death or MI.

Race, racism, and antiracism in emergency medicine: A scoping review of the literature and research agenda for the future

OBJECTIVES

The objective was to conduct a scoping review of the literature and develop consensus-derived research priorities for future research inquiry in an effort to (1) identify and summarize existing research related to race, racism, and antiracism in emergency medicine (EM) and adjacent fields and (2) set the agenda for EM research in these topic areas.

METHODS

A scoping review of the literature using PubMed and EMBASE databases, as well as review of citations from included articles, formed the basis for discussions with community stakeholders, who in turn helped to inform and shape the discussion and recommendations of participants in the Society for Academic Emergency Medicine (SAEM) consensus conference. Through electronic surveys and two virtual meetings held in April 2021, consensus was reached on terminology, language, and priority research questions, which were rated on importance or impact (highest, medium, lower) and feasibility or ease of answering (easiest, moderate, difficult).

RESULTS

A total of 344 articles were identified through the literature search, of which 187 met inclusion criteria; an additional 34 were identified through citation review. Findings of racial inequities in EM and related fields were grouped in 28 topic areas, from which emerged 44 key research questions. A dearth of evidence for interventions to address manifestations of racism in EM was noted throughout.

CONCLUSIONS

Evidence of racism in EM emerged in nearly every facet of our literature. Key research priorities identified through consensus processes provide a roadmap for addressing and eliminating racism and other systems of oppression in EM.

Sex and Race Differences in the Evaluation and Treatment of Young Adults Presenting to the Emergency Department With Chest Pain

Background Acute myocardial infarctions are increasingly common among young adults. We investigated sex and racial differences in the evaluation of chest pain (CP) among young adults presenting to the emergency department. Methods and Results Emergency department visits for adults aged 18 to 55 years presenting with CP were identified in the National Hospital Ambulatory Medical Care Survey 2014 to 2018, which uses stratified sampling to produce national estimates. We evaluated associations between sex, race, and CP management before and after multivariable adjustment. We identified 4152 records representing 29 730 145 visits for CP among young adults. Women were less likely than men to be triaged as emergent (19.1% versus 23.3%, respectively, P<0.001), to undergo electrocardiography (74.2% versus 78.8%, respectively, P=0.024), or to be admitted to the hospital or observation unit (12.4% versus 17.9%, respectively, P<0.001), but ordering of cardiac biomarkers was similar. After multivariable adjustment, men were seen more quickly (hazard ratio [HR], 1.15 [95% CI, 1.05-1.26]) and were more likely to be admitted (adjusted odds ratio, 1.40 [95% CI, 1.08-1.81]; P=0.011). People of color waited longer for physician evaluation (HR, 0.82 [95% CI, 0.73-0.93]; P<0.001) than White adults after multivariable adjustment, but there were no racial differences in hospital admission, triage level, electrocardiography, or cardiac biomarker testing. Acute myocardial infarction was diagnosed in 1.4% of adults in the emergency department and 6.5% of admitted adults. Conclusions Women and people of color with CP waited longer to be seen by physicians, independent of clinical features. Women were independently less likely to be admitted when presenting with CP. These differences could impact downstream treatment and outcomes.

Gender differences, inequalities and biases in the management of Acute Coronary Syndrome

OBJECTIVE

The approach to Acute Coronary Syndrome from a gender perspective is relatively recent. Research is extensive at epidemiological and clinical levels. However, available evidence, besides neglecting the social dimensions of the disease, has made women invisible. The objective of this review was to analyze the inequalities and gender biases in Acute Coronary Syndrome, from the beginning of the disease process to the final resolution.

METHODS

An exhaustive review of the literature of the entire health care process, from risk factors to rehabilitation and recovery, was carried out. The search for articles on gender, gender inequalities, or gender bias was conducted in indexed journals of social and health sciences. Also, a specific search was performed for each stage of the process, such as risk factors, prehospital phase, diagnosis, treatment, and rehabilitation.

RESULTS

Results showed the presence of gender biases throughout the entire health care process in Acute Coronary Syndrome. It is shown gender inequalities in the access to medical care, including a poor recognition among women themselves as well as among health professionals; longer prehospital delays; inadequate diagnoses and treatments; or less assistance to cardiac rehabilitation programmes. These biases occurred at the different levels of the health services involved. Finally, this review included recommendations proposed or arising from the revised papers.

CONCLUSIONS

Reducing gender biases in Acute Coronary Syndrome implies developing strategies to raise awareness among women, improve training of professionals serving at the different levels of health services, reduce delays, develop health management measures, and promote a research agenda.

Gender Disparities in Cardiac Catheterization Rates Among Emergency Department Patients With Chest Pain

BACKGROUND

Previous studies have noted differences in rates of cardiac testing based on gender of patients. We evaluated cardiac catheterization rates for men and women presenting to the emergency department (ED) with chest pain, particularly among patients without a history of myocardial infarction (MI) or recent positive stress test.

METHODS

We performed a prospective evaluation of patients presenting to an urban, academic medical center for assessment of chest pain. We recorded baseline information, testing, and outcomes related to ED, observation unit, and inpatient stay. Primary outcomes included gender differences in cardiac catheterization and stenting rates among patients without an MI or positive stress test.

RESULTS

Over the 5.5 year study period, 2242 ED patients with chest pain participated in the study (45% male). Men and women had similar rates of cardiac stress testing (16.7% vs. 15.2%, P = 0.317) as well as similar rates of positive cardiac stress testing (2.9% vs. 1.9%, P = 0.116). Men were more likely to undergo cardiac catheterization (10.4% vs. 4.9%, P < 0.001). Men who had neither MI nor positive stress test were more likely than women to undergo cardiac catheterization: 5.8% versus 3.3%, P = 0.010. Similarly, men in this group were more likely to experience stent placement: 2.1% versus 0.7%, P = 0.003.

CONCLUSIONS

Similar to previous studies, we noted disparities in cardiac testing by gender. Men were more likely to go to cardiac catheterization without an MI or a positive stress test. This disparity in a more aggressive strategy of cardiac catheterization in men may result in higher stenting rates in this group.

High-Risk Chief Complaints I: Chest Pain-The Big Three (an Update)

Nontraumatic chest pain is a frequent concern of emergency department patients, with causes that range from benign to immediately life threatening. Identifying those patients who require immediate/urgent intervention remains challenging and is a high-risk area for emergency medicine physicians where incorrect or delayed diagnosis may lead to significant morbidity and mortality. This article focuses on the 3 most prevalent diagnoses associated with adverse outcomes in patients presenting with nontraumatic chest pain, acute coronary syndrome, thoracic aortic dissection, and pulmonary embolism. Important aspects of clinical evaluation, diagnostic testing, treatment, and disposition and other less common causes of lethal chest pain are also discussed.

Anxiety Associated With Increased Risk for Emergency Department Recidivism in Patients With Low-Risk Chest Pain

Anxiety contributes to the chest pain symptom complex in 30% to 40% of patients with low-risk chest pain seen in the emergency department (ED). The validated Hospital Anxiety Depression Scale-Anxiety subscale (HADS-A) has been used as an anxiety screening tool in this population. The objective was to determine the prevalence of abnormal HADS-A scores in a cohort of low-risk chest pain patients and test the association of HADS-A score with subsequent healthcare utilization and symptom recurrence. In a single-center, prospective, observational cohort study of adult ED subjects with low-risk chest pain, the HADS-A was used to stratify participants into 2 groups: low anxiety (score <8) and high anxiety (score ≥8). At 45-day follow-up, chest pain recurrence was assessed by patient report, whereas ED utilization was assessed through chart review. Of the 167 subjects enrolled, 78 (47%) were stratified to high anxiety. The relative risk for high anxiety being associated with at least one 30-day ED return visit was 2.6 (95% confidence interval 1.4 to 4.7) and this relative risk increased to 9.1 (95% confidence interval 2.18 to 38.6) for 2 or more ED return visits. Occasional chest pain recurrence was reported by more subjects in the high anxiety group, 68% vs 47% (p = 0.029). In conclusion, 47% of low-risk chest pain cohort had abnormal levels of anxiety. These patients were more likely to have occasional recurrence of their chest pain and had an increased risk multiple ED return visits.

A Systematic Review of the Impact of Physician Implicit Racial Bias on Clinical Decision Making

OBJECTIVES

Disparities in diagnosis and treatment of racial minorities exist in the emergency department (ED). A better understanding of how physician implicit (unconscious) bias contributes to these disparities may help identify ways to eliminate such racial disparities. The objective of this systematic review was to examine and summarize the evidence on the association between physician implicit racial bias and clinical decision making.

METHODS

Based on PRISMA guidelines, a structured electronic literature search of PubMed, CINAHL, Scopus, and PsycINFO databases was conducted. Eligible studies were those that: 1) included physicians, 2) included the Implicit Association Test as a measure of implicit bias, 3) included an assessment of physician clinical decision making, and 4) were published in peer-reviewed journals between 1998 and 2016. Articles were reviewed for inclusion by two independent investigators. Data extraction was performed by one investigator and checked for accuracy by a second investigator. Two investigators independently scored the quality of articles using a modified version of the Downs and Black checklist.

RESULTS

Of the 1,154 unique articles identified in the initial search, nine studies (n = 1,910) met inclusion criteria. Three of the nine studies involved emergency providers including residents, attending physicians, and advanced practice providers. The majority of studies used clinical vignettes to examine clinical decision making. Studies that included emergency medicine (EM) providers had vignettes relating to treatment of acute myocardial infarction, pain, and pediatric asthma. An implicit preference favoring white people was common across providers, regardless of specialty. Two of the nine studies found evidence of a relationship between implicit bias and clinical decision making; one of these studies included EM providers. This one study found that EM and internal medicine residents who demonstrated an implicit preference for white individuals were more likely to treat white patients and not black patients with thrombolysis for myocardial infarction. Evidence from the two studies reporting a relationship between physician implicit racial bias and decision making was low in quality.

CONCLUSIONS

The current literature indicates that although many physicians, regardless of specialty, demonstrate an implicit preference for white people, this bias does not appear to impact their clinical decision making. Further studies on the impact of implicit racial bias on racial disparities in ED treatment are needed.
