Bias in Observed Assessments in Medical Education: A Scoping Review.

PURPOSE: Observed assessments are integral to medical education but may be biased against structurally marginalized communities. Current understanding of assessment bias is limited because studies have focused on single specialties, levels of training, or social identity characteristics (SIDCs). This scoping review maps studies investigating bias in observed assessments in medical education arising from trainees' observable SIDCs at different medical training levels, with consideration of medical specialties, assessment environments, and assessment tools. METHOD: MEDLINE, Embase, ERIC, PsycINFO, Scopus, Web of Science Core Collection, and Cochrane Library were searched for articles published between January 1, 2008, and March 15, 2023, on assessment bias related to 6 observable SIDCs: gender (binary), gender nonconformance, race and ethnicity, religious expression, visible disability, and age. Two authors reviewed the articles, with conflicts resolved by consensus or a third reviewer. Results were interpreted through group review and informed by consultation with experts and stakeholders. RESULTS: Sixty-six of 2,920 articles (2.3%) were included. These studies most frequently investigated graduate medical education (44 [66.7%]), used quantitative methods (52 [78.8%]), and explored gender bias (63 [95.5%]). No studies investigated gender nonconformance, religious expression, or visible disability. One evaluated intersectionality, with SIDCs described inconsistently. General surgery (16 [24.2%]) and internal medicine (12 [18.2%]) were the most studied specialties. Simulated environments (37 [56.0%]) were studied more frequently than clinical environments (29 [43.9%]). Bias favoring men was found more in assessments of intraoperative autonomy (5 of 9 [55.6%]), whereas clinical examination bias often favored women (15 of 19 [78.9%]). When race and ethnicity bias was identified, it consistently favored White students. CONCLUSIONS: This review mapped studies of gender, race, and ethnicity bias in the medical education assessment literature, finding limited studies on other SIDCs and intersectionality. These findings will guide future research by highlighting the importance of consistent terminology, unexplored SIDCs, and intersectionality.

The use of virtual nominal groups in healthcare research: An extended scoping review.

INTRODUCTION: The Nominal Group Technique (NGT) is a consensus group method used to synthesize expert opinions. Given the global shift to virtual meetings, the extent to which researchers leveraged virtual platforms is unclear. This scoping review explores the use of the vNGT in healthcare research during the COVID-19 pandemic. METHODS: Following the Arksey and O'Malley's framework, eight cross-disciplinary databases were searched (January 2020-July 2022). Research articles that reported all four vNGT stages (idea generation, round robin sharing, clarification, voting) were included. Media Synchronicity Theory informed analysis. Corresponding authors were surveyed for additional information. RESULTS: Of 2,589 citations, 32 references were included. Articles covered healthcare (27/32) and healthcare education (4/32). Platforms used most were Zoom, MS Teams and GoTo but was not reported in 44% of studies. Only 22% commented on the benefits/challenges of moving the NGT virtually. Among authors who responded to our survey (16/32), 80% felt that the vNGT was comparable or superior. CONCLUSIONS: The vNGT provides several advantages such as the inclusion of geographically dispersed participants, scheduling flexibility and cost savings. It is a promising alternative to the traditional in-person meeting, but researchers should carefully describe modifications, potential limitations, and impact on results.

Epidemiology of back pain visits and medication usage among United States emergency departments from 2016 to 2023.

INTRODUCTION: Low back pain is a common reason for presentation to the Emergency Department (ED). However, there are limited large-scale, recent data on the epidemiology, disposition, and medication administration for this condition. The objective of this was to assess the incidence, admission rates, medication administrations, and discharge prescriptions among ED visits for low back pain in the United States. METHODS: This was a cross-sectional study of ED presentations for low back pain from 1/1/2016 to 12/31/2023 using the Epic Cosmos database. All ED visits for adults with low back pain identified by ICD-10 codes were included. Outcomes included admission rates, distribution of opioid, benzodiazepine, (non-benzodiazepine) muscle relaxant, acetaminophen, NSAID, and corticosteroid medications administered in the ED, and distribution of opioid, benzodiazepine, muscle relaxant, and corticosteroid medications given upon discharge. Subgroup analyses were performed by specific medication. RESULTS: Of 207,154,419 ED encounters, 12,241,240 (5.9%) were due to back pain with 1,957,299 of these (16.0%) admitted. The admission rate increased over time from 12.8% to 17.1%. The most common medication given in the ED was opioids (40.7%), followed by acetaminophen (37.8%), NSAIDs (22.6%), muscle relaxants (18.4%) benzodiazepines (12.8%), and corticosteroids (5.5%). The most common medications prescribed upon discharge were muscle relaxants (32.1%), followed by opioids (23.2%), corticosteroids (12.2%), and benzodiazepines (3.0%). CONCLUSION: Low back pain represents a common reason for presentation to the ED, and admissions have been increasing over time. Opioids remain the most common ED medication, whereas muscle relaxants have arisen as the most common discharge prescription. These findings can help inform health policy decisions, resource allocation, and evidence-based interventions for medication administration.

Ultrasound-guided paramedian approach: A novel technique for lumbar puncture in the Emergency Department.

Lumbar puncture is performed to evaluate for multiple neurologic conditions, including meningitis and subarachnoid hemorrhage. However, success rates with the landmark-based technique are limited. Ultrasound is most commonly used for pre-marking without dynamic guidance, which presents several limitations, including absence of real-time guidance and lack of reliability if any patient movement occurs after skin marking. We describe a novel, ultrasound-guided paramedian approach which was successfully performed in the Emergency Department setting for lumbar puncture. Physicians should consider this technique as an alternate model using real-time guidance to reduce needle passes in those with difficult anatomy.

Emergency medicine updates: Upper gastrointestinal bleeding.

INTRODUCTION: Upper gastrointestinal bleeding (UGIB) is a condition commonly seen in the emergency department (ED). Therefore, it is important for emergency clinicians to be aware of the current evidence regarding the diagnosis and management of this disease. OBJECTIVE: This paper evaluates key evidence-based updates concerning UGIB for the emergency clinician. DISCUSSION: UGIB most frequently presents with hematemesis. There are numerous causes, with the most common peptic ulcer disease, though variceal bleeding in particular can be severe. Nasogastric tube lavage for diagnosis is not recommended based on the current evidence. A hemoglobin transfusion threshold of 7 g/dL is recommended (8 g/dL in those with myocardial ischemia), but patients with severe bleeding and hemodynamic instability require emergent transfusion regardless of their level. Medications that may be used in UGIB include proton pump inhibitors, prokinetic agents, and vasoactive medications. Antibiotics are recommended for those with cirrhosis and suspected variceal bleeding. Endoscopy is the diagnostic and therapeutic modality of choice and should be performed within 24 h of presentation in non-variceal bleeding after resuscitation, though patients with variceal bleeding may require endoscopy within 12 h. Transcatheter arterial embolization or surgical intervention may be necessary. Intubation should be avoided if possible. If intubation is necessary, several considerations are required, including resuscitation prior to induction, utilizing preoxygenation and appropriate suction, and administering a prokinetic agent. There are a variety of tools available for risk stratification, including the Glasgow Blatchford Score. CONCLUSIONS: An understanding of literature updates can improve the ED care of patients with UGIB.

Incorporating implementation science principles into curricular design.

Implementation science (IS) is an approach focused on increasing the application of evidence-based health interventions into practice, through purposive and thoughtful planning to maximize uptake, scalability, and sustainability. Many of these principles can be readily applied to medical education, to help augment traditional approaches to curriculum design. In this paper, we summarize key components of IS with an emphasis on application to the medical educator.

Letters of Reference in the Current Era.

ABSTRACT: Letters of reference (LORs) are a common component of the application process for residency training programs. With the United States Medical Licensing Examination Step 1 transitioning to pass/fail grading and with the increasing use of holistic review, the potential role of LORs is rising in importance. Among some key benefits are the ability to provide a broader and more holistic view of applicants, which can include highlighting elements of experiences or skills that could be missed in their application, as well as providing a third-party assessment of the applicant external to their rotation experiences. However, LORs also face issues, including variation in quality, challenges with comparability, and risk of bias. In this article, the authors discuss the unique benefits, limitations, and best practice recommendations for LORs in academic medicine. The authors also discuss future directions, including the role of artificial intelligence, unblinded, and co-created LORs.

Emergency medicine updates: Lower gastrointestinal bleeding.

INTRODUCTION: Lower gastrointestinal bleeding (LGIB) is a condition commonly seen in the emergency department. Therefore, it is important for emergency medicine clinicians to be aware of the current evidence regarding the diagnosis and management of this disease. OBJECTIVE: This paper evaluates key evidence-based updates concerning LGIB for the emergency clinician. DISCUSSION: LGIB is most commonly due to diverticulosis or anorectal disease, though there are a variety of etiologies. The majority of cases resolve spontaneously, but patients can have severe bleeding resulting in hemodynamic instability. Initial evaluation should focus on patient hemodynamics, the severity of bleeding, and differentiating upper gastrointestinal bleeding from LGIB. Factors associated with LGIB include prior history of LGIB, age over 50 years, and presence of blood clots per rectum. Computed tomography angiography is the imaging modality of choice in those with severe bleeding to diagnose the source of bleeding and guide management when embolization is indicated. Among stable patients without severe bleeding, colonoscopy is the recommended modality for diagnosis and management. A transfusion threshold of 7 g/dL hemoglobin is recommended based on recent data and guidelines (8 g/dL in those with myocardial ischemia), though patients with severe bleeding and hemodynamic instability should undergo emergent transfusion. Anticoagulation reversal may be necessary. If bleeding does not resolve, embolization or endoscopic therapies are necessary. There are several risk scores that can predict the risk of adverse outcomes; however, these scores should not replace clinical judgment in determining patient disposition. CONCLUSIONS: An understanding of literature updates can improve the care of patients with LGIB.

Artificial intelligence and point-of-care ultrasound: Benefits, limitations, and implications for the future.

The utilization of artificial intelligence (AI) in medical imaging has become a rapidly growing field as a means to address contemporary demands and challenges of healthcare. Among the emerging applications of AI is point-of-care ultrasound (POCUS), in which the combination of these two technologies has garnered recent attention in research and clinical settings. In this Controversies paper, we will discuss the benefits, limitations, and future considerations of AI in POCUS for patients, clinicians, and healthcare systems.

Transvenous Pacemaker Placement: A Review for Emergency Clinicians.

BACKGROUND: Transvenous pacemaker placement is an integral component of therapy for severe dysrhythmias and a core skill in emergency medicine. OBJECTIVE: This narrative review provides a focused evaluation of transvenous pacemaker placement in the emergency department setting. DISCUSSION: Temporary cardiac pacing can be a life-saving procedure. Indications for pacemaker placement include hemodynamic instability with symptomatic bradycardia secondary to atrioventricular block and sinus node dysfunction; overdrive pacing in unstable tachydysrhythmias, such as torsades de pointes; and failure of transcutaneous pacing. Optimal placement sites include the right internal jugular vein and left subclavian vein. Insertion first includes placement of a central venous catheter. The pacing wire with balloon is then advanced until electromechanical capture is obtained with the pacer in the right ventricle. Ultrasound can be used to guide and confirm lead placement using the subxiphoid or modified subxiphoid approach. The QRS segment will demonstrate ST segment elevation once the pacing wire tip contacts the endocardial wall. If mechanical capture is not achieved with initial placement of the transvenous pacer, the clinician must consider several potential issues and use an approach to evaluating the equipment and correcting any malfunction. Although life-saving in the appropriate patient, complications may occur from central venous access, right heart catheterization, and the pacing wire. CONCLUSIONS: An understanding of transvenous pacemaker placement is essential for emergency clinicians.

Oh, the places you'll go! A qualitative study of resident career decisions in emergency medicine.

Objectives: Postresidency career choices are complex decisions that involve personal, professional, and financial preferences and may be influenced by training programs. It is unknown how residents navigate these decisions during emergency medicine (EM) residency. We explored EM residents' perspectives on career decision making and how residency programs can support career planning. Methods: We conducted semistructured interviews at seven accredited EM residency programs from diverse locations and training formats. We used purposive sampling to reflect the diversity of trainees with regard to gender, level of training, and career plans. Two researchers independently coded the transcripts. We used a constructivist-interpretivist paradigm to guide our thematic analysis. Results: We interviewed 11 residents and identified major themes in three categories. Residents described being exposed to career options through formalized curricula such as required rotations, career fairs, and subspeciality tracks, highlighting the importance of access to faculty with diverse areas of clinical and academic expertise. Many noted that exposure was often self-driven. We identified three major themes regarding career decisions: instrumental factors, people involved, and processes of decision making. Instrumental factors included personal interests, goals, and values as well as practice characteristics, financial considerations, timing, and opportunity costs. Mentors and family were highly involved in resident career decisions. Residents often utilized reflection and conversations with mentors and peers in their decision-making process. Participants recommended that programs provide exposure to diverse career options early in training, protect time for career education, and ensure adequate mentorship and a supportive community. Participants suggested specific curricular content and strategies to support career decisions. Conclusions: This study illuminates important factors involved in resident career decision making and how programs can support their trainees. Essential components include diverse experiences and building a reflective mentorship environment.
