Bilateral Emboli and Highest Heart Rate Predict Hospitalization of Emergency Department Patients With Acute, Low-Risk Pulmonary Embolism. Ann Emerg Med 2023; 82:369-380. [PMID: 37028997 PMCID: PMC11126867 DOI: 10.1016/j.annemergmed.2023.02.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Revised: 02/14/2023] [Accepted: 02/16/2023] [Indexed: 04/09/2023]
Abstract
STUDY OBJECTIVE Some patients with acute pulmonary embolism (PE) will suffer adverse clinical outcomes despite being low risk by clinical decision rules. Emergency physician decisionmaking processes regarding which low-risk patients require hospitalization are unclear. Higher heart rate (HR) or embolic burden may increase short-term mortality risk, and we hypothesized that these variables would be associated with an increased likelihood of hospitalization for patients designated as low risk by the PE Severity Index. METHODS This was a retrospective cohort study of 461 adult emergency department (ED) patients with a PE Severity Index score of fewer than 86 points. Primary exposures were the highest observed ED HR, most proximal embolus location (proximal vs distal), and embolism laterality (bilateral vs unilateral PE). The primary outcome was hospitalization. RESULTS Of 461 patients meeting inclusion criteria, most (57.5%) were hospitalized, 2 patients (0.4%) died within 30 days, and 142 (30.8%) patients were at elevated risk by other criteria (Hestia criteria or biochemical/radiographic right ventricular dysfunction). Variablesassociated with an increased likelihood of admission were highest observed ED HR of ≥110 beats/minute (vs HR <90 beats/min) (adjusted odds ratio [aOR] 3.11; 95% confidence interval [CI] 1.07 to 9.57), highest ED HR 90 to 109 (aOR 2.03; 95% CI 1.18-3.50) and bilateral PE (aOR 1.92; 95% CI 1.13 to 3.27). Proximal embolus location was not associated with the likelihood of hospitalization (aOR 1.19; 95% CI 0.71 to 2.00). CONCLUSIONS Most patients were hospitalized, often with recognizable high-risk characteristics not accounted for by the PE Severity Index. Highest ED HR of ≥90 beats/min and bilateral PE were associated with a physician's decision for hospitalization.

Ann Emerg Med 2023; 82:381-393. [PMID: 37596016 PMCID: PMC10440853 DOI: 10.1016/j.annemergmed.2023.02.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2023] [Revised: 02/21/2023] [Accepted: 02/28/2023] [Indexed: 08/20/2023]
Abstract
STUDY OBJECTIVE Although recommended by professional society guidelines, outpatient management of low-risk pulmonary embolism (PE) from emergency departments (EDs) in the US remains uncommon. The objective of this study was to identify barriers and facilitators to the outpatient management of PE from the ED using implementation science methodology. METHODS We conducted semistructured interviews with a purposeful sample of emergency physicians using maximum variation sampling, aiming to recruit physicians with diverse practice patterns regarding the management of low-risk PE. We developed an interview guide using the implementation science frameworks-the Consolidated Framework for Implementation Research and the Theoretical Domains Framework. Interviews were recorded, transcribed, and analyzed in an iterative process. RESULTS We interviewed 26 emergency physicians from 11 hospital systems, and the participants were diverse with regard to years in practice, practice setting, and engagement with outpatient management of PE. Although outer setting determinants, such as medicolegal climate, follow-up, and insurance status were universal, our participants revealed that the importance of these determinants were moderated by individual-level and inner setting determinants. Prominent themes included belief in consequences, belief in capabilities, and institutional support and culture. Inertia of clinical practice and complexity of the process were important subthemes. CONCLUSION In this qualitative study, clinicians reported common barriers and facilitators that initially focused on outer setting and external barriers but centered on clinician beliefs, fear, and local culture. Efforts to increase outpatient treatment of select patients with acute PE should be informed by these barriers and facilitators, which are aligned with the deimplementation theory.

Home treatment versus early discharge for the outpatient management of acute pulmonary embolism: A non-interventional, post-hoc cohort analysis. Thromb Res 2023; 227:25-33. [PMID: 37209588 DOI: 10.1016/j.thromres.2023.05.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Revised: 03/06/2023] [Accepted: 05/08/2023] [Indexed: 05/22/2023]
Abstract
INTRODUCTION We prospectively investigated whether home treatment of pulmonary embolism (PE), is as effective and safe as the recommended early discharge management in terms of outcomes at 3 months. METHODS We performed a post hoc analysis of prospectively and consecutively recorded data in acute PE patients from a tertiary care facility between January 2012 and November 2021. Home treatment was defined as discharge to home directly from the emergency department (ED) after <24 h stay. Early discharge was defined as in-hospital stay of ≥24 h and ≤48 h. Primary efficacy and safety outcomes were a composite of PE-related death or recurrent venous thrombo-embolism, and major bleeding, respectively. Outcomes between groups were compared using penalized multivariable models. RESULTS In total, 181 patients (30.6 %) were included in the home treatment group and 463 (69.4 %) patients in the early discharge group. Median duration of ED stay was 8.1 h (IQR, 3.6-10.2 h) in the home treatment group, and median length of hospital stay was 36.4 h (IQR, 28.7-40.2) in the early discharge group. The adjusted rate of the primary efficacy outcome was 1.90 % (95 % CI, 0.16-15.2) vs 2.05 % (95 % CI, 0.24-10.1) for home treatment vs early discharge (hazard ratio (HR) 0.86 (95 % CI, 0.27-2.74). The adjusted rates of the primary safety outcome did not differ between groups at 3 months. CONCLUSIONS In a non-randomized cohort of selected acute PE patients, home treatment provided comparable rates of adverse VTE and bleeding events to the recommended early discharge management, and appears to have similar clinical outcomes at 3 months.

Clinical decision support to Optimize Care of patients with Atrial Fibrillation or flutter in the Emergency department: protocol of a stepped-wedge cluster randomized pragmatic trial (O'CAFÉ trial). Trials 2023; 24:246.

Abstract
BACKGROUND Management of adults with atrial fibrillation (AF) or atrial flutter in the emergency department (ED) includes rate reduction, cardioversion, and stroke prevention. Different approaches to these components of care may lead to variation in frequency of hospitalization and stroke prevention actions, with significant implications for patient experience, cost of care, and risk of complications. Standardization using evidence-based recommendations could reduce variation in management, preventable hospitalizations, and stroke risk. METHODS We describe the rationale for our ED-based AF treatment recommendations. We also describe the development of an electronic clinical decision support system (CDSS) to deliver these recommendations to emergency physicians at the point of care. We implemented the CDSS at three pilot sites to assess feasibility and solicit user feedback. We will evaluate the impact of the CDSS on hospitalization and stroke prevention actions using a stepped-wedge cluster randomized pragmatic clinical trial across 13 community EDs in Northern California. DISCUSSION We hypothesize that the CDSS intervention will reduce hospitalization of adults with isolated AF or atrial flutter presenting to the ED and increase anticoagulation prescription in eligible patients at the time of ED discharge and within 30 days. If our hypotheses are confirmed, the treatment protocol and CDSS could be recommended to other EDs to improve management of adults with AF or atrial flutter.
