Reliability of a Measure of Admission Intensity for Emergency Physicians.

Study Objective: We assess the stability of a measure of emergency department (ED) admission intensity for value-based care programs designed to reduce variation in ED admission rates. Measure stability is important to accurately assess admission rates across sites and among physicians.

Methods: We sampled data from 358 EDs in 41 states (January 2018 to December 2021), separate from sites where the measure was derived.

Are Smaller Emergency Departments More Prone to Volume Variability?

Introduction: Daily patient volume in emergency departments (ED) varies considerably between days and sites. Although studies have attempted to define "high-volume" days, no standard definition exists. Furthermore, it is not clear whether the frequency of high-volume days, by any definition, is related to the size of an ED.

Emergency physicians' active patient queues over the course of a shift.

Objectives: When emergency physicians see new patients in an ad libitum system, they see fewer patients as the shift progresses. However, it is unclear if this reflects a decreasing workload, as patient assessments often span many hours. We sought to investigate whether the size of a physician's queue of active patients similarly declines over a shift.

Modelling attending physician productivity in the emergency department: a multicentre study.

Objectives: Emergency physician productivity, often defined as new patients evaluated per hour, is essential to planning clinical operations. Prior research in this area considered this a static quantity; however, our group's study of resident physicians demonstrated significant decreases in hourly productivity throughout shifts. We now examine attending physicians' productivity to determine if it is also dynamic.

The Impact of Hospital and Patient Factors on the Emergency Department Decision to Admit.

Background: Substantial variation exists in rates of emergency department (ED) admission. We examine this variation after accounting for local and community characteristics.

Objectives: Elucidate the factors that contribute to admission variation that are amenable to intervention with the goal of reducing variation and health care costs.

The relative contribution of provider and ED-level factors to variation among the top 15 reasons for ED admission.

Study Objective: We examine adult emergency department (ED) admission rates for the top 15 most frequently admitted conditions, and assess the relative contribution in admission rate variation attributable to the provider and hospital.

Methods: This was a retrospective, cross-sectional study of ED encounters (≥18years) from 19 EDs and 603 providers (January 2012-December 2013), linked to the Area Health Resources File for county-level information on healthcare resources. "Hospital admission" was the outcome, a composite of inpatient, observation, or intra-hospital transfer.

How (ED) admission decisions differ when the same physician works in two different emergency department.

Study Objective: Emergency physicians often work in multiple hospital emergency departments (EDs). We study how emergency physician admission decisions vary in different settings.

Methods: We conducted a retrospective, cross-sectional study over two years (2012-3) in six EDs in three states.
