Emerging Adulthood

688
Jeffrey Arnett's concept of emerging adulthood offers a framework to understand the unique developmental stage between adolescence and full-fledged adulthood, generally from ages 18 to 25. This period is marked by extensive exploration and shifts in identity, relationships, and career choices, a process known in psychology as role experimentation. Emerging adulthood reflects the evolving cultural expectations surrounding adulthood and the dynamic process of personal transformation during...

Introduction Cardiac Emergencies

365
Cardiac emergencies are critical situations involving the heart that require immediate medical intervention to prevent severe complications or death. These emergencies often arise from underlying heart conditions that impair the heart's ability to function correctly.Types of Cardiac EmergenciesThe most common types of cardiac emergencies include Acute Coronary Syndrome (ACS), myocardial infarction (MI), cardiac arrest, and heart failure.Acute Coronary Syndrome (ACS)Acute Coronary Syndrome (ACS)...

Applications of GIS: Disaster Management and Emergency Response

520
Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

X-ray Imaging

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans),  magnetic resonance imaging (MRI),  functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Summary
This summary is machine-generated.

A small group of frequent emergency department (ED) imaging users, termed "imaging superusers," consume nearly half of all imaging services. Identifying these patients may help control costs and radiation exposure.

Area of Science:

  • Radiology
  • Healthcare Management
  • Health Services Research

Background:

  • Emergency department (ED) imaging utilization is a significant driver of healthcare costs and patient radiation exposure.
  • Understanding patterns of high imaging use is crucial for resource optimization and patient safety.

Purpose of the Study:

  • To identify and characterize the most frequent users of emergency department (ED) imaging within a healthcare system.
  • To differentiate between high-utilizing patients based on visit frequency versus imaging frequency.

Main Methods:

  • A retrospective analysis of all patients with at least one ED visit in 2016 across a four-hospital system.
  • Characterization of ED imaging utilization, defining
  • clinical superusers
  • (≥4 ED visits) and
  • imaging superusers
  • (≥4 ED imaging exams).

Main Results:

  • 12.3% of patients accounted for 49.5% of all ED imaging services.
  • A distinct subgroup of 1.3% of ED patients underwent >10 annual ED examinations (
  • imaging superusers
  • ) and consumed 12.4% of all imaging services.
  • Imaging superusers underwent significantly more imaging examinations than clinical superusers, despite similar ED visit frequencies.

Conclusions:

  • A small percentage of ED patients are responsible for a disproportionately large share of imaging services.
  • ED imaging superusers are a distinct group from clinical superusers.
  • Prospective identification of imaging superusers could enable targeted interventions to reduce imaging volume, costs, and radiation exposure.
