Trends in severe pediatric emergency conditions in a national cohort, 2008 to 2014.
The objective of this study was to determine the incidence and recent trends in serious pediatric emergency conditions. Data from the Nationwide Emergency Department Sample 2008-2014 was used, and included patients less than18 years of age with a serious condition. Findings showed that the most common serious condition in children presenting to United States emergency departments was serious respiratory disease, while anaphylaxis was the fastest increasing serious condition.

Consolidating emergency department-specific data to enable linkage with large administrative datasets.
This paper looks at the challenges and opportunities presented by consolidating hospital-level data with patient-level data to create better analyses of hospital-based specialties, units, or departments, and patient outcomes. The American Hospital Association (AHA) has hospital-level data, while the Centers for Medicare & Medicaid Services (CMS) has patient-level data which can be used to study emergency departments (EDs). A distinct database discussed in this paper is the Nationwide Emergency Department Inventory (NEDI). However, the NEDI database lists EDs individually while the AHA and CMS databases list EDs individually or by group if they are part of a larger network. A test set using EDs from New England was conducted using individually matched NEDI EDs with corresponding EDs in the AHA and CMS. A “group match” was assigned when more than one NEDI ED was matched to a single AHA or CMS facility ID number. Of the 195 EDs in the test set, 169 (87%) completed the NEDI survey. Of those, 77% EDs were individually listed in AHA and CMS while 39 were part of groups consisting of 2-3 EDs with one facility ID. The grouped EDs had a larger number of annual visits and beds, were more likely to be freestanding and were less likely to be rural. The consolidated dataset with 171 EDS yielded similar results to the 169 responding EDs which provides a more representative sample for studies.

Nonspecific chest pain and hospital revisits within 7 days of care: variation across emergency department, observation and inpatient visits.
The purpose of this study was to compare the rate at which patients with nonspecific chest pain return to the hospital within 7 days after index observation visits versus after index emergency department and inpatient visits. Findings showed that up to 1 in 10 patients discharged with nonspecific chest pain returned to the hospital within 1week. Compared with emergency department and inpatient care, observation visits were associated with lower revisit rates. Recommendations include further research to refine clinical standards of care for nonspecific chest pain as well as to investigate the healthcare delivery and patient factors that influence 7-day revisit rates.

Assessment of hospital readmissions from the emergency department after implementation of Medicare's hospital readmissions reduction program.
The purpose of this study was to examine whether the Medicare Hospital Readmissions Reduction Program (HRRP) was associated with changes in the probability of readmission at emergency department (ED) visits after hospital discharge (ED revisits) overall and depending on whether admission is typically indicated for the patient's condition at the ED revisit. Using hospital and ED discharge data from California, Florida, and New York, findings suggested that implementation of the HRRP was associated with a lower likelihood of readmission for recently discharged patients presenting to the ED, specifically for congestive heart failure. These findings highlighted the critical role of the ED in readmission reduction under the HRRP and suggested that patient outcomes after HRRP implementation merit further study.

Association of pemphigus and pemphigoid with osteoporosis and pathological fractures.
Researchers sought to determine whether pemphigus and bullous pemphigoid (BP) are associated with osteoporosis and fractures in the US. Subjects for this cross-sectional study included adults with pemphigus or with BP from the 2006-2012 National Emergency Department Sample. The researchers found that, when compared to BP, pemphigus was associated with higher odds of osteopenia, osteoporosis, and fractures, particularly of the ulna and radius. Patients with pemphigus or BP as well as long-term systemic corticosteroid use had the highest odds of osteoporosis and fractures. The researchers suggested that patients with these conditions may benefit from increased screening for osteoporosis and interventions to prevent fractures.

Trends in regionalization of emergency care for common pediatric conditions.
This study examined trends in regionalization of emergency care for common pediatric conditions. The authors sought to determine how the likelihood of definitive care has changed for 3 common conditions: asthma, croup, and gastroenteritis. They used the National Emergency Department Sample Database to study children from 2008 to 2016 who presented to emergency departments with those primary diagnoses, excluding critically ill patients. Researchers conducted analyses by stratification of annual emergency department pediatric volume categorized by quartiles. Referral rates increased for all conditions in all volume quartiles, with referral rates greatest in the lowest pediatric volume quartile.

Association of asthma with osteopenia, osteoporosis, osteomalacia, and fractures.
Previous studies that examined the relationship between asthma, osteoporosis, and pathologic fractures found conflicting results. The objective of this study was to determine whether asthma was associated with osteopenia, osteoporosis, osteomalacia, and fractures in U.S. adults. The investigators concluded that ED visits with asthma were associated with osteopenia, osteoporosis, osteomalacia, and pathologic fractures.

Variation in emergency department admission rates across the United States.
The authors investigated factors related to variation in hospital-level emergency department (ED) admission rates. Using HCUP data, they found that higher proportions of Medicare and uninsured patients, more inpatient beds, lower ED volumes, for-profit ownership, trauma center status, and higher hospital occupancy rates were associated with higher ED admission rates.

Impact of the fall 2009 influenza A(H1N1)pdm09 pandemic on US hospitals.
The authors investigated the impact of the 2009 influenza A(H1N1)pdm09 pandemic on US hospitals. They found that the fall 2009 pandemic period substantially impacted US hospitals, mostly through increased emergency department visits. Furhter, for a small proportion of hospitals that experienced a high surge in inpatient admissions, increased mortality from selected clinical conditions was associated with both prepandemic outcomes and surge, highlighting the linkage between daily hospital operations and disaster preparedness.
