Improving ED Emergency Severity Index Acuity Assignment Using Machine Learning and Clinical Natural Language Processing.

Introduction: Triage is critical to mitigating the effect of increased volume by determining patient acuity, need for resources, and establishing acuity-based patient prioritization. The purpose of this retrospective study was to determine whether historical EHR data can be used with clinical natural language processing and machine learning algorithms (KATE) to produce accurate ESI predictive models.

Methods: The KATE triage model was developed using 166,175 patient encounters from two participating hospitals.

The Three-Year Effect of Medicaid Expansion on Emergency Department Visits and Admissions.

Study Objective: We examine the effect of the Medicaid expansion in 2014 under in the Patient Protection and Affordable Care Act on emergency department (ED) utilization and ED admission rates (fraction of ED visits that lead to hospital admission) during the first 3 postexpansion years (2014 to 2016).

Methods: We compared ED utilization and ED admission rates in 151 EDs in 14 expansion states with those in 376 EDs in 14 nonexpansion states, using difference-in-differences methods with data from 3 national emergency medicine groups from 2013 to 2016.

Results: In expansion states, the volume of Medicaid-paid ED visits increased 49% (95% confidence interval 34% to 65%), and the volume of uninsured visits decreased 44% (95% confidence interval -52% to -34%) relative to that of nonexpansion states.

Choosing wisely in emergency medicine: Early results and insights from the ACEP emergency quality network (E-QUAL).

Purpose: To characterize performance among ED sites participating in the Emergency Quality Network (E-QUAL) Avoidable Imaging Initiative for clinical targets on the American College of Emergency Physicians Choosing Wisely list.

Methods: This was an observational study of quality improvement (QI) data collected from hospital-based ED sites in 2017-2018. Participating EDs reported imaging utilization rates (UR) and common QI practices for three Choosing Wisely targets: Atraumatic Low Back Pain, Syncope, or Minor Head Injury.

Imaging in Suspected Renal Colic: Systematic Review of the Literature and Multispecialty Consensus.

Purpose: Renal colic is common and CT (computerized tomography) is frequently utilized when the diagnosis of kidney stone is suspected. CT is accurate, but exposes patients to ionizing radiation and has not been shown to alter either interventional approaches or hospital admission rates. This multi-organizational transdisciplinary collaboration sought evidence-based, multispecialty consensus on optimal imaging across different clinical scenarios in patients with suspected renal colic in the acute setting.

Emergency physician evaluation of PA and NP practice patterns.

Unlabelled: The unprecedented surge in physician assistants (PAs) and NPs in the ED developed quickly in recent years, but scope of practice and practice patterns are not well described.

Methods: We conducted two cross-sectional electronic surveys of the American College of Emergency Physicians' council. Survey construction was informed by interviews and evaluated with validity and reliability studies.

TRIAD VIII: Nationwide Multicenter Evaluation to Determine Whether Patient Video Testimonials Can Safely Help Ensure Appropriate Critical Versus End-of-Life Care.

Objective: End-of-life interventions should be predicated on consensus understanding of patient wishes. Written documents are not always understood; adding a video testimonial/message (VM) might improve clarity. Goals of this study were to (1) determine baseline rates of consensus in assigning code status and resuscitation decisions in critically ill scenarios and (2) determine whether adding a VM increases consensus.

Medicaid Expansion In 2014 Did Not Increase Emergency Department Use But Did Change Insurance Payer Mix.

In 2014 twenty-eight states and the District of Columbia had expanded Medicaid eligibility while federal and state-based Marketplaces in every state made subsidized private health insurance available to qualified individuals. As a result, about seventeen million previously uninsured Americans gained health insurance in 2014. Many policy makers had predicted that Medicaid expansion would lead to greatly increased use of hospital emergency departments (EDs).

Innovative staffing in emergency departments: the role of midlevel providers.

NPs and PAs are increasingly common in US and Canadian EDs. Emergency medicine is a unique specialty with a vast knowledge base performed in a high-risk environment; therefore, supervisory models and regulatory requirements developed for lower-risk settings (e.g.

Assessment of Medicare's imaging efficiency measure for emergency department patients with atraumatic headache.

Study Objective: Computed tomography (CT) use has increased rapidly, raising concerns about radiation exposure and cost. The Centers for Medicare & Medicaid Services (CMS) developed an imaging efficiency measure (Outpatient Measure 15 [OP-15]) to evaluate the use of brain CT in the emergency department (ED) for atraumatic headache. We aim to determine the reliability, validity, and accuracy of OP-15.

Interventions to improve the timeliness of emergency care.

With a persistent trend of increasing emergency department (ED) volumes every year, services are intensifying. Thus, improving the timeliness of delivering emergency care should be a primary focus, both from an operational and from a research perspective. Much has been published on factors associated with delays in emergency care, and the next phase in this area of research will focus on exploring interventions to improve the timeliness of care.

A survey of the use of time-out protocols in emergency medicine.

Background: Time-outs, as one of the elements of the Joint Commission Universal Protocol for Preventing Wrong Site, Wrong Procedure, and Wrong Person Surgery has been in effect since July 1, 2004. Time-outs are required by The Joint Commission for all hospital procedures regardless of location, including emergency departments (EDs). Attitudes about ED time-outs were assessed for a sample of senior emergency physicians serving in leadership roles for a national professional society.

Improving handoffs in the emergency department.

Patient handoffs at shift change are a ubiquitous and potentially hazardous process in emergency care. As crowding and lengthy evaluations become the standard for an increasing proportion of emergency departments (EDs), the number of patients handed off will likely increase. It is critical now more than ever before to ensure that handoffs supply valid and useful shared understandings between providers at transitions of care.
