Introduction: Vagal maneuvers are first-line therapy for hemodynamically stable supraventricular tachycardia (SVT), yet the relative efficacy of the standard Valsalva Maneuver (SVM), modified Valsalva maneuver (MVM), carotid-sinus massage (CSM), and head-down deep breathing (HDDB) remains uncertain. We undertook a network meta-analysis (NMA) to define the optimal technique and explore age- and sex-related effect modification.

Methods: We searched nine databases from inception to January 2025 for randomized controlled trials involving adults (≥ 18 years of age) with stable SVT treated with at least two of the four maneuvers. Primary outcomes were conversion to sinus rhythm after a single attempt after multiple attempts, and by the end of the trial. Secondary outcomes were the need for rescue intravenous (IV) antiarrhythmic drugs and maneuver-related adverse events (AEs). Bayesian random-effects NMA generated risk ratios (RR) with 95% credible intervals (CrIs); surface under the cumulative ranking curve (SUCRA) quantified hierarchy. We performed consistency, publication bias, and sensitivity analyses, and network meta-regression for mean age and female proportion.

Results: Nineteen trials (n = 2,545) formed a connected network. The MVM was more than doubly effective for single-attempt conversion relative to the SVM (RR 2.71, 95% CrI, 2.26-3.31) and outperformed CSM (RR 6.57, 3.33-14.94) and HDDB (RR 1.30, 0.35-4.66); SUCRA = 88.7%. At the end of the trial, the MVM retained superiority over the SVM (RR 1.25, 1.03-1.56) and ranked the highest success rate (SUCRA = 81.3%). The MVM also reduced IV drug use vs the SVM (RR 0.64, 0.55-0.73) and CSM (RR 0.59, 0.37-0.90). No maneuver differed in multiple-attempt success or AEs. The HDDB technique was ranked highest in safety (SUCRA = 82.4%) but was supported only by a single, small study. Meta-regression showed no age or sex interaction. Inconsistency was minimal; the Egger test suggested small-study effects only for the IV-drug endpoint (P = .03).

Conclusion: The MVM provides the greatest likelihood of rapid sinus rhythm restoration and the least need for rescue pharmacotherapy without increasing AEs, supporting its adoption as the default vagal strategy for SVT. Larger, standardized trials are warranted to confirm safety differentials and long-term outcomes.

Introduction: The guaiac fecal occult blood test, originally designed for colorectal cancer screening, is frequently used in emergency departments (ED) to detect occult gastrointestinal (GI) bleeding. However, the test has low sensitivity and specificity, leading to potential false positives and negatives. This study evaluates the current practices and perceptions of emergency physicians and hospitalists regarding the utility of the guaiac test in the setting of suspected GI bleeding in the ED.

Objective: Our primary aim in this study was to evaluate the current practice and views of emergency physicians and hospitalists on the utility of the stool guaiac test in the ED.

Methods: We conducted a multicenter survey from January 3-April 3, 2024, across four hospital systems, targeting attending physicians in the ED and hospitalists. Participants were asked to rate their agreement with statements about the stool guaiac test on a scale of 1 (strongly disagree) to 5 (strongly agree).

Results: Response rates were 47/93 (50.5%) for emergency attendings and 9/18 (50%) for hospitalists. Emergency attendings were significantly less likely than hospitalists to agree that stool guaiac testing is important for evaluating GI bleeding (31% vs 67%, P < .001). More than half of emergency attendings (55%) reported often performing the test, while 44% of hospitalists reported frequently requesting it before accepting a patient. Although 70% of emergency attendings believed that guaiac results influence hospitalists' admission decisions (P = .02), 67% of hospitalists stated they would accept a patient with suspected GI bleeding even without a result. Despite rating the test as important, only 33% of hospitalists felt that stool guaiac testing frequently changes management during hospitalization. Overall, the groups showed distinct attitudes regarding the utility and impact of stool guaiac testing.

Conclusion: The guaiac fecal occult blood test remains widely used despite skepticism among emergency attendings regarding its importance. Hospitalists were more likely to request the test but acknowledged it rarely changes patient management. These findings highlight the need for re-evaluation of guaiac testing in acute care settings and improved communication between ED and inpatient teams. Further research should explore the clinical impact of removing routine stool guaiac testing.

Introduction: Resuscitation of critically injured patients requires effective team leadership. Poor communication is the leading cause of sentinel events. Closed-loop communication reduces error during trauma resuscitations. Nonetheless, previous studies show few verbal orders are audible. Verbal orders during trauma resuscitations have not been studied for completeness. In this project we aimed to assess whether verbal orders for medications and blood products during trauma resuscitations were complete, audible, and used closed-loop communication.

Methods: This was an observational assessment of a convenience sample of verbal orders that trauma captains gave for medications and blood products during the primary and secondary survey. It was conducted in an academic emergency department (ED) at an adult Level 1 trauma center. We assessed medication orders for the presence or absence of medication name, dose, and route. Blood orders were evaluated for the presence or absence of blood product (packed cells or whole blood) and type (O- or O+). We recorded orders as audible or inaudible. Closed-loop communication was recorded as present or absent. Orders were considered complete if they included all elements. We used descriptive statistics to analyze data.

Results: There were 186 verbal orders enrolled: 165 (88.7%) for medications and 21 (11.3% for blood products. For medication verbal orders, 77.9% (n=127) were audible, 73.6% (n=120) included the name, 62.0% (n=101) included the dose, 17.8% (n=29) included the route, and 73.5% (n=111) used closed-loop communication. Overall, 23 (14.1%) medication verbal orders were complete. Regarding verbal orders for blood, 16 (76.2%) were audible, three (14.3%) included the blood product, seven (33.3%) included the blood type, and 13 (61.9%) used closed-loop communication. Overall, 0% (n=0) of the blood product verbal orders were complete.

Conclusion: Audible, complete verbal orders, and closed-loop communication were underused during trauma resuscitations. Interventions to improve communication of verbal orders warrant evaluation in the ED.

Introduction: Discrimination and bias based on race/ethnicity permeate the medical education system. Racial disparities in assessment measures can ultimately impact applicants' Match results. Few studies to date have examined the narrative portion of the emergency medicine (EM) Standardized Letter of Evaluation (SLOE) for language differences by race. In this study we aimed to determine whether there were language differences by race in the narrative portion of the EM SLOE.

Methods: This study is an analysis of word category frequencies in the narrative portion of the SLOE for applicants applying to EM residency. The sample was drawn from the students who applied to the study institution in 2022. The narrative portion of the SLOE and other applicant factors were collected from the Electronic Residency Application Service (ERAS) applications and de-identified. We compared the number of SLOEs containing predefined keywords by race using chi2 analysis. Keywords were identified in six thematic word categories: agency; standout traits; ability; grindstone habits; achievement; and compassion. We performed logistic regression to determine whether any differences remained after controlling for other factors in the application.

Results: Of 1,104 applicants to the institution, 2,288 SLOEs with self-identified race/ethnicity were available for analysis. Black and Hispanic applicants had higher proportions of SLOEs that contained a compassion word than White applicants (24.9% and 22.4% vs 16.9%, respectively). This finding persisted after controlling for other factors in the application for Black applicants (odds ratio 1.61, 95% CI 1.1-2.36]). There was no evidence of difference in word use by race across other thematic categories.

Conclusion: We found differences in the proportion of SLOEs containing compassion words in the narrative portion of the EM SLOE between Black and White applicants, with Black applicants being described with compassion language more frequently. However, we found no difference in any other word category, indicating less overall disparity than other narrative assessment studies.

Introduction: Emergency departments (ED) present unique challenges for elderly patients who often experience higher revisit rates, increased number of complications, and worse health outcomes. This study examines the impact of implementing a combined automated screening callback and Geriatric Emergency Nurse Initiative Expert (GENIE)-led callback system on reducing ED revisit rates among elderly patients.

Methods: We conducted a retrospective analysis that compared revisit rates before and after the implementation of a GENIE callback system in the ED of a large, Level 1 trauma academic center. The study cohort included 23,664 patients, and the primary outcome was revisits at three, seven, and 30 days post-discharge from the ED. Data were adjusted for the Emergency Severity Index (ESI), age group, and sex. The cost of this initiative came from a three-year grant of $650,000 from the Gary and Mary West Foundation, which included the salary for a GENIE nurse.

Results: Revisit ratios in the pre-intervention period were 4.8%, 8.9%, and 17.2% at three, seven, and 30 days after discharge, respectively. Following implementation of the callback system, those ratios decreased to 3.9%, 7.6%, and 15.2% at the corresponding time points. All reductions were statistically significant (P < .001) and remained significant after adjusting for ESI, age group, and sex.

Conclusion: The GENIE callback system effectively reduced ED revisits among elderly patients, highlighting the importance of structured follow-up communication and care. These findings support the expansion of such programs to improve patient outcomes and reduce healthcare costs.

Introduction: Take-home naloxone (THN) programs in emergency departments (ED) can reduce opioid overdose deaths by providing naloxone directly to at-risk patients before discharge. However, sustainable models that integrate reimbursement and workflow alignment remain limited.

Methods: A reimbursable ED-led THN program was developed across a large regional health system. The program used electronic health record (EHR)-integrated ordering, on-site kit dispensing, and third-party insurance billing when available. Kits were stocked in automated medication dispensing systems and supplemented by city-provided stock for uninsured patients. Pilot outcomes included kits dispensed and reimbursement rates across eight participating EDs.

Results: A total of 2,520 naloxone kits were dispensed across eight EDs between January 2019-December 2024, with a total of 6,551 encounters with decision support prompting naloxone ordering (31.6% of eligible). The proportion of kits reimbursed by insurance rose from 46% in 2019 to 95% by 2025. In total, 89.9% of kits were reimbursed either by insurance or public supply (the rest paid by the hospital system). Kit distribution grew from 99 in 2019 to 702 in 2024, reflecting expanded site participation, improved workflows, and greater staff engagement.

Conclusion: A reimbursable ED-led naloxone program can increase access to life-saving medication for patients at risk of opioid overdose. Integrating take-home naloxone distribution into EHR workflows, leveraging insurance billing, and partnering with public health agencies offers a sustainable, low-barrier model that other health systems can adopt.

Introduction: Poisoning-induced out-of-hospital cardiac arrest (P-OHCA) is a leading mortality cause; however, no specific prognostic model exists for P-OHCA. In this study we aimed to develop and validate a novel scoring system, the WAIVOR score, which identifies factors associated with survival to hospital discharge in patients with P-OHCA, including the nature of the toxic agent.

Methods: In this retrospective nationwide observational study we analyzed 4,252 South Korean adult P-OHCA cases from 2013-2023. The study population was randomly stratified into derivation (n = 2,834) and validation (n = 1,418) cohorts. Independent factors associated with survival to hospital discharge were identified through multivariable logistic regression analysis, yielding adjusted odds ratios (aOR) and 95% confidence intervals (CI). We assessed the scoring system's discriminative performance using the receiver operating characteristic curve and area under the curve (AUC) analysis, with optimal threshold determination via the Youden index.

Results: Among all patients, 291 (6.8%) survived to hospital discharge. The most frequent poisoning substances were gases/vapors (45.3%), pesticides (31.5%), and medically prescribed drugs (12.0%). Six independent factors associated with survival to hospital discharge were incorporated into the WAIVOR score (maximum 11 points): pre-hospital return of spontaneous circulation, four points (aOR 16.11, 95% CI 10.16-25.64); witnessed arrest, two points (aOR 3.86, 95% CI 2.61-5.71); age < 65 years, two points (aOR 3.34, 95% CI 2.20-5.15); female sex, one point (aOR 1.54, 95% CI 1.09-2.16); and arrest-to-emergency department intervals ≤ 30 minutes, two points (aOR 3.44, 95% CI 2.00-6.09; 31-60 minutes, one point (aOR 1.77, 95% CI 1.08-3.02); and poisoning by non-gas/non-vapor substances, one point (aOR 0.54, 95% CI 0.33-0.89). The WAIVOR score demonstrated robust discriminative performance (AUC: 0.823 and 0.739 in derivation and validation cohorts, respectively). At the optimal threshold of five points, the score demonstrated 53.6% sensitivity, 84.4% specificity, 19.8% positive predictive value, and 96.2% negative predictive value (NPV).

Conclusion: The WAIVOR score represents a practical tool whose associated factors may help assess potential for survival to hospital discharge in patients with P-OHCA. Its high NPV renders it valuable for identifying poor prognostic outcomes. However, further external validation studies are required before this score can be broadly used in decisions regarding resuscitation termination in clinical practice.

Introduction: Although humility is a key leadership trait linked to collaboration and trust, current residency application processes lack methods to identify it. By examining whether themes of humility appear in the Standardized Letters of Evaluation (SLOE) of medical students who later became emergency medicine (EM) chief residents, we sought to determine the presence of humility-related traits in SLOEs and explore their potential to inform the identification of applicants with leadership potential during residency selection.

Methods: Two independent reviewers examined 104 SLOEs (52 chief, 52 non-chief) from 2015-2021, representing 43 students (21 who later assumed chief resident positions and 22 who did not) between 2018-2024 at a single academic EM residency program. A third reviewer resolved all coding disagreements. Reviewers deductively analyzed all written comments, targeting elements associated with humility as conceptualized by Tangney (2000) and Gruppen (2015). A SLOE was categorized as containing elements of humility if at least one clearly defined construct (such as openness to feedback, recognition of limitations, or concern for others) was identified. Sections of the data displaying the most convergence of humility elements underwent open coding, revealing emerging themes.

Results: Nineteen of 21 (90.5%) chief residents had letters encompassing elements of humility compared to only 10 of 22 (45.5%) non-chief residents (P < .01). Openness was the most prominent element noted, followed by the need to make changes in performance, concern for others, and confidence. Further analysis of comments that highlighted humility uncovered several other themes including commitment and advocacy, eagerness to learn and improve, and maturity and responsibility.

Conclusion: This study highlights specific humility-related traits noted in the Standard Letters of Evaluation of fourth-year medical students who later became chief residents in emergency medicine, offering preliminary insights into how qualitative evaluation tools may capture characteristics associated with future leadership roles.

Introduction: Deimplementation is the process through which an existing practice, procedure, or protocol is discontinued. Past deimplementation efforts in emergency medical services (EMS), such as reduction of liberal oxygen administration, backboard use, and lights and sirens responses, have been slow in rates of change and had varying levels of adoption. Our objective in this study was to analyze the deimplementation of albuterol administration in the beginning of the 2019 novel coronavirus (COVID-19) pandemic for the adoption of deimplementation guidelines, rate of change, and factors leading to this change in EMS practice.

Methods: Using the 2020 National Emergency Medical Services Information System (NEMSIS) dataset, we analyzed the change in EMS calls with albuterol administration following the US Centers for Disease Control and Prevention (CDC) advisory recommending limiting aerosol-generating procedures in response to the COVID-19 pandemic.

Results: The 2020 NEMSIS dataset included 43,488,767 total records, and 449,290 (1.0%) records included at least one albuterol administration. Calls with albuterol administration dropped 61.7% in a near-linear fashion in the six weeks following the publication of the CDC's guidance (from March 8-April 18, 10,426 absolute reduction; from 16,891 to 6,465, in average calls per week with albuterol administration). In the period before the guidance, there were on average 16,891 calls with albuterol administration of 640,597 (2.6%) calls per week. In the period after the guidance, there were, on average, 6,465 calls with albuterol administration of 601,943 (1.1%) calls per week. Therefore, while total EMS calls declined by 6% during the transition period, the proportion of albuterol calls within this decline went down by 1.5% (2.6% to 1.1%), reflecting rapid deimplementation.

Conclusion: Deimplementation of albuterol administration in the beginning of the COVID-19 pandemic was significant in its rate and success in adherence to guidelines when compared to other changes in EMS policies, procedures, and protocols. A better understanding of deimplementation can guide future EMS efforts to phase out ineffective practices while minimizing disruption to care.

Introduction: Transfers between emergency departments (ED) can have an important impact on patient care and experience. We examined interfacility transfers from an academic ED due to insurance status to determine whether they disproportionately affected minority demographics.

Objective: Our objective was to determine whether interfacility transfers for non-contracted insurance status disproportionately affected minority patients in our hospital ED.

Methods: We extracted data from the hospital's electronic health record system. Records for patients who underwent facility transfer were reviewed to determine which transfers were due to insurance contracting status. We compared the number of patients transferred for insurance incompatibility with the number admitted to the same hospital as initially seen in the ED, either to observation or inpatient status, for groups with socioeconomic minority status including Hispanic, Hispanic non-White, Black, Native American, and non-English speaking.

Results: We identified 2,031 total interfacility transfers. Of these, 735 (36.2%) met inclusion criteria, and 49.7 % (366/735) of these transfers were due to insurance incompatibility. The total transfer rate for all patients was .93% (366/39,299). Increased transfer rates due to insurance incompatibility were observed for all minority demographics queried. The most severe disparity in effect size was for non-English speakers (2.06% compared to 0.90% for English-speakers; 2.32 odds ratio [OR], P < .001). Patients with Hispanic ethnicity experience insurance transfer in 1.31% of cases compared to 0.87% for non-Hispanic whites (OR 1.52, P < .001). The insurance transfer rate for all non-White patients was elevated at 1.11%, but this did not rise to the level of statistical significance (OR 1.28, P = .06).

Conclusion: In our single-center ED study, minority patient populations were disproportionately impacted by interfacility transfers for non-contracted insurance status. We found increased transfer rates due to insurance incompatibility for all minority demographics queried. The most severe disparity was found for non-English speakers and patients with Hispanic ethnicity.
