Background: Vertigo is a priority for training and decision support in emergency departments (ED). Benign paroxysmal positional vertigo (BPPV), though manageable at bedside, remains frequently underdiagnosed and undertreated. This study assessed the effectiveness of a two-tiered educational intervention on posterior and horizontal BPPV management in the ED setting.

Methods: Longitudinal program evaluation study conducted over a year in a French ED, following GRACE-3 guidelines, involving patients with triggered episodic vestibular syndrome or brief vertigo without nystagmus. Two 6-month periods were compared: before (control cohort) and after (intervention cohort) an educational intervention of standardized training and an online decision support tool. The primary outcome was the prevalence of evidence-based BPPV diagnoses.

Results: Of the 382 patients included, 166 were in the control cohort (43.5%) and 216 were in the intervention cohort (56.5%). The intervention cohort had a higher rate of evidence-based BPPV diagnoses compared to the control cohort (38.0% vs. 16.9%), with an effect size of 21.1 (95% confidence interval [CI] 11.5-29.6, p < 0.0001). Canalith repositioning maneuvers were performed more frequently in the intervention cohort (90.2% vs. 57.7%), with an effect size of 33.1 (95% CI 13.2-53.1). Posttreatment tests showed a nonsignificant difference of 79.5% of intervention cohort patients testing negative versus 75.0% in the control cohort. ED length of stay was shorter in the intervention cohort (137 min vs. 247 min), with an effect size of -109.5 (95% CI -154.0 to -65.0). ED revisits within 1 month were similar (2.3% vs. 1.2%). During the intervention period, clinicians' satisfaction was correlated with the effectiveness of their clinical management.

Conclusions: A standardized educational intervention demonstrated enhancing BPPV screening and improved evidence-based diagnosis, showing promise of more efficient treatment in the ED. Further multicenter studies are warranted to evaluate impacts on patient-reported outcomes and resource optimization.

Background: Suicide is the 10th leading cause of death in the United States. Prior research suggests that 10% of people who died by suicide received some form of emergency department (ED) treatment in the 2 months preceding death. The risk of attempted suicide is high during transition back to the community after discharge from the ED, so this is an important opportunity to develop effective empirically validated prevention methods. However, the physical layout and crowded nature of most contemporary EDs, resulting in high rates of "hallway bed" assignments, presents some ethical challenges to conducting the requisite behavioral health research in ED settings.

Methods and results: In this report, we illustrate the clinical/research ethics controversy through the example of a specific ED-based suicide prevention research protocol, in which the proposed hallway bed recruitment was initially rejected by the institutional review board (IRB) based on concerns about privacy, data confidentiality, and related considerations. Through a consultation process that involved the IRB representatives, the research team (including ethicists), and ED personnel, along with the collection of data to evaluate the risk of compromised confidentiality in hallway bed settings, a viable and ethically grounded approach was reached.

Conclusions: This example illustrates the ethical considerations when enrolling patients who occupy a hallway bed into research and the value of a collaborative/problem solving focused dialogue between investigators, ethicists, and IRB personnel.

Objectives: For emergency department (ED) patients, lung cancer may be detected early through incidental lung nodules (ILNs) discovered on chest CTs. However, there are significant errors in the communication and follow-up of incidental findings on ED imaging, particularly due to unstructured radiology reports. Natural language processing (NLP) can aid in identifying ILNs requiring follow-up, potentially reducing errors from missed follow-up. We sought to develop an open-access, three-step NLP pipeline specifically for this purpose.

Methods: This retrospective used a cohort of 26,545 chest CTs performed in three EDs from 2014 to 2021. Randomly selected chest CT reports were annotated by MD raters using Prodigy software to develop a stepwise NLP "pipeline" that first excluded prior or known malignancy, determined the presence of a lung nodule, and then categorized any recommended follow-up. NLP was developed using a RoBERTa large language model on the SpaCy platform and deployed as open-access software using Docker. After NLP development it was applied to 1000 CT reports that were manually reviewed to determine accuracy using accepted NLP metrics of precision (positive predictive value), recall (sensitivity), and F1 score (which balances precision and recall).

Results: Precision, recall, and F1 score were 0.85, 0.71, and 0.77, respectively, for malignancy; 0.87, 0.83, and 0.85 for nodule; and 0.82, 0.90, and 0.85 for follow-up. Overall accuracy for follow-up in the absence of malignancy with a nodule present was 93.3%. The overall recommended follow-up rate was 12.4%, with 10.1% of patients having evidence of known or prior malignancy.

Conclusions: We developed an accurate, open-access pipeline to identify ILNs with recommended follow-up on ED chest CTs. While the prevalence of recommended follow-up is lower than some prior studies, it more accurately reflects the prevalence of truly incidental findings without prior or known malignancy. Incorporating this tool could reduce errors by improving the identification, communication, and tracking of ILNs.

Objective: Gender-minority youth, whose gender identity differs from their sex assigned at birth, have elevated suicide risk compared to cisgender youth, yet few studies examine their suicide risk in the emergency department (ED). Our objectives were to determine the prevalence of and assess risk and protective factors associated with prior suicide attempt (SA) and recent suicide ideation (SI) among gender-minority adolescents in the ED.

Methods: We conducted a secondary analysis of gender-minority adolescents in the Emergency Department Screening for Teens at Risk for Suicide (ED-STARS) multicenter, random-series prospective cohort study. Prior SA and recent SI were based on the Columbia Suicide Severity Rating Scale and Ask Suicide-Screening Questions, respectively. We conducted Firth's logistic regressions to assess risk and protective factors associated with prior SA and recent SI.

Results: Of 6641 adolescent participants in ED-STARS, 280 (4.2%) identified as gender minority. Of the gender minorities, 72% presented with a nonpsychiatric complaint, 37% admitted to a prior SA, and 25% reported recent SI. Prior SA was associated with the number of self-harm methods in the prior 12 months (adjusted odds ratio [aOR] 1.5, 95% confidence interval [CI] 1.3-1.9), sexual minority (aOR 5.0, 95% CI 2.5-10.6), and mother's history of prior SA (aOR 3.6, 95% CI 1.5-9.2). Recent SI was associated with hopelessness (aOR 4.2, 95% CI 1.5-13.9), lower positive affect (aOR 0.9, 95% CI 0.8-1.0), sexual minority (aOR 8.3, 95% CI 2.5-37.8), five or more self-harm events in the prior 12 months (aOR 4.9, 95% CI 2.1-11.6), and number of illicit drug classes (aOR 1.9, 95% CI 1.2-3.2).

Conclusions: Among gender-minority ED adolescent patients, one in three experienced a SA prior to the ED visit. One in four endorsed SI within 2 weeks of the ED visit. The identified risk and protective factors among gender-minority adolescents may inform future ED-based efforts to detect and reduce suicide risk.

Background: Emergency department (ED) visits may serve as opportunities for firearm injury prevention and intervention efforts. Our objective was to determine ED utilization by youth before and after firearm injury.

Methods: We performed a retrospective cohort study of ED encounters by youth (0-18 years old) with firearm injury from eight states using the 2019 State ED and Inpatient Databases. Our primary outcome was an ED encounter (1) 90 days before or (2) 90 days after index injury. We used generalized estimating equations, accounting for hospital clustering, to determine associations between ED utilization and ED type (pediatric vs. general), youth age, sex, race and ethnicity, urbanicity, and insurance status.

Results: We identified 1035 ED encounters for firearm injury (median [IQR] age 17 (15-18) years, 85.3% male, 63.3% non-Hispanic Black, 68.6% publicly insured, 90.5% living in a metropolitan area, 52.8% general ED). In the 90 days before an index injury, 12.8% of youth had an ED encounter; of these, 68.2% occurred in general EDs, and 18.2% were for trauma. In the 90 days after an index injury, 22.1% of youth had an ED encounter; of these, 50.0% occurred in general EDs, and 22.6% were for trauma. We found no significant association between ED type and ED utilization patterns. Few youths changed ED type across longitudinal encounters.

Conclusions: Youth have high rates of ED utilization before and after firearm injury. Half of firearm-injured youth receive their emergency care exclusively in general EDs. Implementing firearm injury prevention and intervention efforts in all ED settings is critical.

Background: Oregon introduced a state policy, HB 3090, on October 6, 2017, which increased requirements on emergency departments (EDs) to improve transitions to outpatient mental health care. The objective of this study was to examine the policy's impact among low-income adolescent patients who face severe barriers to follow-up.

Methods: This was a retrospective cohort study of visits by Medicaid enrollees ages 14-18 presenting to any Oregon ED for a mental health concern between January 1, 2016, and December 31, 2019. We calculated standardized mean differences and used interrupted time series models to evaluate the association of HB 3090 with 14-day mental health follow-up, in-ED services, and inpatient admissions, adjusting for gender, race/ethnicity, primary language, and calendar months.

Results: Among 26,071 adolescent mental health-related ED visits, we found an estimated increase of 3.63 percentage points (pp; 95% confidence interval [CI] 0.27 to 6.99) in the adjusted probability of a 14-day outpatient mental health claim postpolicy. However, this effect was attenuated over time, with a slope change of -0.25 pp (95% CI -0.5 to 0) for each month thereafter. The probability of receiving mental health services in the ED or inpatient admission did not change in association with the policy.

Conclusions: There was a small increase in short-term outpatient mental health visits after the policy, but the association weakened over time, and other key outcomes did not change. Putting pressure on EDs to perform better in this area is likely to be a minimally effective strategy without accompanying strengthening of mental health resources.
