CONTEXT The potential effects of increasing numbers of uninsured and underinsured persons on US emergency departments (EDs) is a concern for the health care safety net. OBJECTIVE To describe the changes in ED visits that occurred from 1997 through 2007 in the adult and pediatric US populations by sociodemographic group, designation of safety-net ED, and trends in ambulatory care-sensitive conditions. DESIGN, SETTING, AND PARTICIPANTS Publicly available ED visit data from the National… 

Figures and Tables from this paper

US Emergency Department Use by Children, 2001–2010
TLDR
The use of ED by children is growing faster than population growth, and the intensity of ED care has risen sharply, particularly among Hispanic children and Medicaid beneficiaries.
Access to Primary Care and Visits to Emergency Departments in England: A Cross-Sectional, Population-Based Study
TLDR
General practices providing more timely access to primary care had fewer self-referred discharged ED visits per registered patient, and policy makers should consider improving timely accessto primary care when developing plans to reduce ED utilisation.
Disparities in reproductive health-related visits to the emergency department in Maryland by age and race, 1999-2005.
TLDR
Disparities by age and race are evident for reproductive health-related ED visits in Maryland, and many of these ED visits are for conditions that are amenable to preventive measures.
Changes in Emergency Department Care Intensity from 2007–16: Analysis of the National Hospital Ambulatory Medical Care Survey
TLDR
From 2007 to 2016, ED care intensity appears to have increased modestly, including aging of patient population, increased illness severity, and increased resources utilization.
Characteristics of Non-Emergent Visits in Emergency Departments: Profiles and Longitudinal Pattern Changes in Taiwan, 2000–2010
TLDR
It was concluded that non-emergent ED visits were associated with multifaceted factors, but the change to cost-sharing payment, being female, younger age, and geographical residence were the most predictive factors.
Longitudinal Patterns of Emergency Department Visits: A Multistate Analysis of Medicaid Beneficiaries
TLDR
Examination of longitudinal patterns of emergency department (ED) visits among adult fee-for-service Medicaid found primary care resources should be a major focus to reduce the increased burden on the EDs.
Emergency Department Utilization in the U.S. Military Health System.
TLDR
It is shown that abdominal pain and chest pain are the most common reasons for presentation to the ED in the Military Health System and the most most common presenting diagnoses for admission from the ED.
Emergency Department Utilization by Children in the USA, 2010–2011
TLDR
A retrospective cohort study using population-based multipayer data from six geographically-dispersed U.S. states in 2010 and 2011 found a substantial burden of ED visits at both patient- and visit-levels by children.

Emergency Department Visits for Ambulatory Care Sensitive Conditions: Insights Into Preventable Hospitalizations
TLDR
The disproportionate ED utilization for chronic ACS conditions by black persons and Medicaid patients does not appear to be explained by either differences in disease prevalence or disease severity, and follow-up arrangements for black persons, Medicaid, and uninsured patients suggest that they are less likely to have ongoing primary care.

TLDR
High safety-net burden is not necessarily offset by public funding, and the vast majority of EDs that serve high proportions of uninsured patients do not receive such compensation.
Emergency department visitors and visits: who used the emergency room in 2007?
KEY FINDINGS Older adults (aged 75 and over), non-Hispanic black persons, poor persons, and persons with Medicaid coverage were more likely to have had at least one emergency department (ED) visit in

TLDR
Understanding the conditions for which children visit EDs may provide much needed insight into the accessibility of preventive and ambulatory care, as well as assist in improving ED resources for treating child patients.

TLDR
This report marks the first time that the annual estimate of visits has surpassed the billion mark and is also a significant increase from the 1999-2000 estimate, primarily driven by a jump in the number of visits to primary care physicians.
Insured Americans drive surge in emergency department visits.
TLDR
Though insured people accounted for most of the increase in emergency department visits, uninsured Americans increasingly rely on emergency departments because of decreased access to other sources of primary medical care.
Emergency Department Care in California Who Uses It and Why
TLDR
This issue of California Counts describes trends in emergency department capacity and use and creates detailed profiles of emergency department visits, finding that immigrant Hispanics and Asians use emergency departments less than U.S.-born whites, and noncitizen immigrants in particular are among the least likely to report a recent hospital admission.
