Pregnancy-adapted YEARS Algorithm: A Retrospective Analysis.

Introduction: Pulmonary embolism (PE) is an imperative diagnosis to make given its associated morbidity. There is no current consensus in the initial workup of pregnant patients suspected of a PE. Prospective studies have been conducted in Europe using a pregnancy-adapted YEARS algorithm, which showed safe reductions in computed tomography pulmonary angiography (CTPA) imaging in pregnant patients suspected of PE. Our objective in this study was 1) to measure the potential avoidance of CTPA use in pregnant patients if the pregnancy-adapted YEARS algorithm had been applied and 2) to serve as an external validation study of the use of this algorithm in the United States. Methods: This study was a single-system retrospective chart analysis. Criteria for inclusion in the cohort consisted of keywords: pregnant; older than 18; chief complaints of shortness of breath, chest pain, tachycardia, hemoptysis, deep vein thromboembolism (DVT), and D-dimer-from January 1, 2019- May 31,2022. We then analyzed this cohort retrospectively using the pregnancy-adapted YEARS algorithm, which includes clinical signs of a DVT, hemoptysis, and PE as the most likely diagnosis with a D-dimer assay. Patients within the cohort were then subdivided into two categories: aligned with the YEARS algorithm, or not aligned with the YEARS algorithm. Patients who did not receive a CTPA were analyzed for a subsequent diagnosis of a PE or DVT within 30 days. Results: A total of 74 pregnant patients were included in this study. There was a PE prevalence of 2.7% (two patients). Of the 36 patients who did not require imaging by the algorithm, seven CTPA were performed. Of the patients who did not receive an initial CTPA, zero were diagnosed with PE or DVT within a 30-day follow-up. In total, 85.1% of all the patients in this study were treated in concordance with the pregnancy-adapted YEARS algorithm. Conclusion: The use of the pregnancy-adapted YEARS algorithm could have resulted in decreased utilization of CTPA in the workup of PE in pregnant patients, and the algorithm showed similar reductions compared to prospective studies done in Europe. The pregnancy-adapted YEARS algorithm was also shown to be similar to the clinical rationale used by clinicians in the evaluation of pregnant patients, which indicates its potential for widespread acceptance into clinical practice.

Association of Chest Pain Protocol-Discordant Discharge With Outcomes Among Emergency Department Patients With Modest Elevations of High-Sensitivity Troponin.

Importance: Accelerated diagnostic protocols (ADPs) for chest pain using high-sensitivity troponin (hsTn) levels have excellent sensitivity and negative predictive value for rapid risk stratification of patients with chest pain. However, little is known about the outcomes of patients who are discharged despite abnormal ADP results, ie, after "ruling-in" with a modest elevation of hsTn. Objective: To determine outcomes of patients discharged following ADP, including those who were ruled in with modestly elevated levels of hsTnT but discharged nonetheless. Design, Setting, and Participants: This retrospective cohort study included patients with chest pain who presented to the emergency departments (EDs) of a large multisite health system ED between January 2017 to September 2019. Patients were assessed using an ADP, had a peak hsTnT level measured between the limit of quantitation and 52 ng/L, were discharged, and had follow-up in the electronic medical record. Data analysis was conducted from January 2017 to September 2019. Exposures: Application of an hsTnT ADP. Main Outcomes and Measures: Thirty-day major adverse cardiac events (MACE), including myocardial infarction, urgent coronary revascularization, and all-cause death, comparing patients who were discharged following ADP-concordant vs ADP-discordant results. Results: Of 10 342 patients with chest pain (mean [SD] age 51 [17] years; 5902 [57%] women) discharged following ADP, 29 (0.28%) had MACE. Patients with MACE were older (median [IQR] age, 66 [53-75] years vs 50 [38-62] years; P < .001) and more likely to have prior CAD (12 [41.4%] vs 1805 [17.5%]; P = .002) and hyperlipidemia (13 [44.8%] vs 2248 [21.8%]; P = .006). Additionally, patients with MACE were 5-fold more likely to have been discharged despite ADP discordance (16 [55.2%] vs 1145 [11.1%]; P < .001). A multivariable logistic regression analysis revealed only ADP discordance was independently associated with MACE (odds ratio, 6.42 [95% CI, 2.94-14.0]; P < .001). When stratified by peak hsTnT level, there were no differences in MACE between ADP-concordant and -discordant discharges provided the peak hsTnT measured was less than 12 ng/L. In contrast, patients with peak hsTnT level between 12 and 51 ng/L were significantly more likely to have MACE if they were discharged after ADP-discordant vs -concordant hsTnT series (14 of 609 [2.30%] vs 5 of 1047 [0.48%]; P < .002). Notably, a HEART (history, electrocardiogram, age, risk factors, troponin) score of 4 or greater retrospectively identified the most ADP-discordant discharges (13 of 16 [81.3%]) who had MACE. Conclusions and Relevance: In this cohort study, an hsTnT ADP identified patients who could be discharged from the ED with low 30-day risk of MACE, provided the discharge was based on ADP-concordant "rule-out." Conversely, the rate of MACE was significantly higher among patients discharged despite ADP discordance. Most patients with ADP-discordant discharges who experienced MACE had a HEART score of 4 or greater, suggesting that application of this score may augment discharge decisions of patients despite ADP-discordant troponin series.

Residents Are Coming: A Faculty Development Curriculum to Prepare a Community Site For New Learners.

Audience: This curriculum is designed for emergency medicine attendings in varying years of community practice to prepare them for Emergency Medicine (EM) residents. Length of Curriculum: 15 months. Introduction: Emergency medicine is a growing field with new residencies approved every year. A strong, competent cadre of clinical educators is essential to the success of any residency, and new programs have the challenge of developing their clinical faculty into outstanding teachers. There is minimal literature guidance for navigating this transition. Our site is a community tertiary care center in the process of applying for an EM residency. We focus on our experience designing a faculty development curriculum to accommodate the needs of a diverse group of physicians in all stages of their careers. We will demonstrate that a curriculum satisfying all stakeholders can easily be implemented in a way that allows for robust participation without excessive additional administrative burden. Educational Goals: Our goal is to prepare community-based EM attendings to be outstanding educators to future residents by augmenting their knowledge of current educational practice and adult learning theory, literature review, and biostatistics. Educational Methods: The educational strategies used in this curriculum included lectures, guided discussion, small group discussion, and asynchronous learning. Research Methods: This curriculum was implemented in the Geisinger Wyoming Valley Medical center targeted at staff physicians. This educational study was deemed exempt by the institutional review board (IRB). We electronically collected retrospective survey data using a 5-point Likert scale as well as free text responses. The primary measure was agreement with the statement, "Faculty development time makes me feel more prepared to be a clinical educator." We also surveyed whether this was felt to be an appropriate use of time, self-reported growth in key educational and biostatistical domains, and likeliness to change practice based on the material. Results: Responses collected from core faculty after the sessions indicated a uniformly positive review of the series itself with the primary outcome receiving a 4.6 rating on a 5-point Likert scale (strong agreement). Faculty reported that these brief sessions improved the quality of the departmental staff meetings (average rating 4.7/5). Journal club sessions were rated as positive (4.7/5) and attendees self-reported growth in statistical literacy and security in clinical practice. Discussion: We demonstrated successful implementation of a faculty development curriculum that was favorably assessed by all key stakeholders. Faculty self-reported growth in all educational and clinical domains evaluated. It was successfully implemented without substantially increasing the time burden for physicians with robust clinical and administrative schedules. We feel this is generalizable to other sites seeking to start an EM residency and is useful for sites with existing residencies to efficiently deliver content to junior faculty.
