The Impact of the Affordable Care Act Insurance Expansions on Opioid-Related Emergency Department Visits.
The authors leveraged ACA coverage expansions, including Medicaid expansion and Marketplaces, to study the impact of health insurance on opioid-related emergency department (ED) visits. They used ZIP-code–level ED utilization data from HCUP’s State Inpatient Databases (SID) and State Emergency Department Databases (SEDD) for 29 states. They found evidence of a dose-response relationship between pre-ACA uninsured and changes in ED visit rates in both expansion and non-expansion states: areas with higher uninsured rates prior to ACA saw larger reductions in opioid-related ED visits after the ACA took effect. The authors concluded that these findings suggest that increased insurance coverage may to help mitigate the opioid crisis.

Association of homelessness with emergency department use among children in New York.
This research letter describes a cross-sectional study that was conducted to evaluate the association of homelessness with emergency department (ED) use among children in New York. The study used the HCUP State Emergency Department Database and State Inpatient Database for New York including children 18 years and younger with an ED visit between 2014 and 2018. The primary outcome was frequent ED use, defined as 4 or more visits per calendar year. The authors determined visit incident rates for all children for ambulatory care-sensitive conditions (asthma, diabetes, gastroenteritis, urinary tract infection), injuries and poisonings, and mental health problems based on ICD-9 and ICD-10 codes. Frequent ED use was more common among children experiencing homelessness, occurring in 22.1% vs 4.3% of children who were housed. Children experiencing homelessness had higher incidences of asthma, diabetes, urinary tract infections, and mental health problems and lower incidences of injuries and poisonings, which lead to higher admission rates overall (42.1% vs 0.7%) and to ICUs (4.1% vs 0.7%). Admission rates were higher across all diagnoses and to ICUs for asthma, gastroenteritis, and injuries and poisonings. ED usage rates were highest for homeless children aged 12-17 (40.2% of all children).

Racial and ethnic disparities in preventable hospitalizations and ED visits five years after ACA Medicaid expansions,.
This AHRQ-authored paper examined whether the 2014 Affordable Care Act (ACA) Medicaid expansions mitigated existing racial or ethnic disparities in preventable hospitalizations and emergency department (ED) visits. The authors used inpatient data from twenty-nine states and ED data from twenty-six states for the period 2011 to 2018. They found that Medicaid expansions decreased disparities in preventable hospitalizations and ED visits between non-Hispanic Black and White nonelderly adults by 10 percent or more. There were no significant effects on disparities between Hispanic and non-Hispanic White nonelderly adults. Their findings highlight sustained improvements in community-level care for non-Hispanic Black populations, but also suggest access barriers experienced by Hispanic adults that need to be addressed beyond Medicaid eligibility expansion.

Trends in treatment costs of U.S. emergency department visits.
In recent years, emergency department (ED) spending has been increasing more than in other areas of health care. Few studies have focused on changes in ED treatment costs. The purpose of this study was to analyze recent increases in emergency department treatment costs to highlight possibilities for reducing the growth of overall hospital costs. The researchers used data from the Healthcare Cost and Utilization Project (HCUP) and applied Cost-to-Charge Ratios for ED Files to the HCUP Nationwide Emergency Department Sample for 2012 through 2019. The study found that ED treatment costs experienced a 5.4% annual growth rate, increasing from $54 billion to $88 billion, with higher treatment cost per visit responsible for 4.4 of those percentage points. The researchers concluded that the study provides valuable information for decision- and policy-makers by bringing attention to components of the healthcare delivery system with the highest increasing costs as well as trends in overall ED costs.

Association of county-level availability of pediatricians with emergency department visits.
This study examined whether children in counties with more pediatricians had fewer emergency department (ED) visits. The authors conducted a cross-sectional study of all ED visits among children younger than 18 years from 6 states. Each additional pediatrician per 1000 children was associated with a 13.7% decrease in ED visits in the state-adjusted model. In the full model however, there was no association. Other factors such as presence of an urgent care facility, high socioeconomic status, urban status and higher proportions of White race and nonpublic insurance were also associated with decreased ED visit rates.

Association of socioeconomic characteristics with where children receive emergency care.
This study’s objective was to characterize national associations of neighborhood income and insurance type for children with the characteristics of emergency departments (EDs) from which they receive care. The authors conducted a cross-sectional study of ED visits by children from 2014 to 2017 using the Nationwide Emergency Department Sample. Emergency department characteristics were characterized by pediatric volume category. There was a total of 107.6 million ED visits from 2014 to 2017. Children outside of the wealthiest neighborhood income quartile had lower proportions of visits to high-volume pediatric EDs and greater proportions of visits to low-volume pediatric EDs than children in the wealthiest quartile. Publicly insured children were modestly more likely to visit higher-volume pediatric EDs than privately insurance and uninsured children. This association appears to be principally driven by urban-rural differences in access to pediatric emergency care.

Effects of hurricanes on emergency department utilization: an analysis across 7 US storms.
This study examines changes in emergency department (ED) utilization for residents of 344 counties after the occurrence of 7 US hurricanes between 2005 and 2016. Using HCUP data, findings showed that the overall population rate of weekly ED visits changed little post-hurricane, but rates by disease categories and age demonstrated varying results. ED utilization rates for respiratory disorders exhibited the largest post-hurricane increase, especially 2-3 weeks following the hurricane. The change in population rates by disease categories and age tended to be higher for people residing in counties closer to the hurricane path.

Emergency department visits for suicidal ideation and self-harm in rural and urban youths.
The authors sought to compare emergency department (ED) visit rates for suicidal ideation and/or self-harm among youth by urban-rural location of residence. Data was taken from the Nationwide Emergency Department Sample. They found that, compared with youths living in urban areas, youths living in rural areas had higher ED visit rates for self-harm, including self-inflicted firearm injuries. The researchers recommended preventive approaches for self-harm based in community and ED settings in order to help address these differences.

Methods for estimating the cost of treat-and-release emergency department visits.
The objective of this study was to evaluate and compare approaches to estimating the service delivery cost of emergency department (ED) visits from total charge data only. The investigators concluded that when cost-center-level charge detail for ED visits is unavailable, alternative methods relying on total ED charges can estimate ED service costs for patient and hospital segments.

The impact of urgent care centers on nonemergent emergency department visits.
This study looked at the impact of urgent care centers on nonemergency emergency department (ED) use. Secondary data from a novel urgent care center database, linked to the HCUP State Emergency Department Databases (SEDD) from six states was used. Data from ZIP codes with no urgent care centers served as a control group compared to areas with local urgent care centers. Having an open urgent care center in a ZIP code reduced the total number of ED visits by residents by 17.2% largely due to visits for less urgent conditions. The effect was concentrated in areas with hospitals with the longest ED wait times. The total number of uninsured visits to the ED were reduced by 21% and for Medicaid visits by 29.1%.

Patient insurance status is associated with care received after transfer among pediatric patients in the emergency department.
The objective of this study was to determine whether frequency of interfacility transfer varied by insurance status among pediatric emergency department (ED) patients. Secondarily, the investigators tested for an association between insurance status and odds of transfer with discharge from the second ED without observation or admission. The investigators concluded that among ED-to-ED transfers, pediatric patients with public or without insurance were more often kept for observation or admission at the second hospital after transfer.

Measuring complications of serious pediatric emergencies using ICD-10.
The purpose of this study was to create definitions for complications for 16 serious pediatric conditions using the International Classification of Diseases, 10th Revision, Clinical Modification or Procedure Coding System (ICD-10-CM/PCS), and to assess whether complication rates are similar to those measured with ICD-9-CM/PCS. The investigators concluded that for most conditions, incidences and complication rates were similar before and after the transition to ICD-10-CM/PCS codes, suggesting their system identified complications of conditions in administrative data similarly using ICD-9-CM/PCS and ICD-10-CM/PCS codes.

Factors associated with Interhospital transfers of emergency general surgery patients from emergency departments.
This study looked at the factors contributing to transfer of emergency general surgery (EGS) patients to another hospital. Data from the AHRQ Nationwide Emergency Department Sample (NEDS) from 2010-2014 was analyzed. The transfer rate during that time was 1.9%. Patients with Medicare or other insurance had higher odds of transfer compared to patients with private health insurance. Odds of transfer increased with a greater number of comorbid conditions as well as resuscitation, intestinal obstruction, and conditions of the upper gastrointestinal tract. Transfers were more likely to originate from rural hospitals or Level I or II trauma centers.

The association between traumatic dental and brain injuries in American children.
This study examined the association between dento-alveolar trauma (DAT) and traumatic brain injuries (TBIs) among children ages 0-18 years. The Nationwide Emergency Department Sample (NEDS), an HCUP dataset, was analyzed using ICD-9-CM codes for the 2010-2014 NEDS data. Out of 6,281,658 emergency department (ED) visits, DAT was recorded in 93,408 (1.5%) visits and TBI was recorded in 996,334 (15.9%) visits. Of the DAT-positive encounters, 7.5% had codes associated with TBI. Patients with DAT had 0.20 odds of having TBI compared with patients who did not DAT when all confounding variables were kept constant. Multiple injuries, being involved in motor vehicle crashes, and injuries due to assault were associated with higher odds of concomitant TBI in patients who sustained DAT.

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.

Trends in US physician diagnosis of child physical abuse and neglect injuries, 2006-2014.
The purpose of this study was to determine if US child physical abuse and neglect injury rates changed from 2006 to 2014, whether definitive diagnoses of physical abuse and neglect were used more often over time, and what patient factors influenced definitive physical maltreatment diagnoses. The investigators found that definitive diagnoses of physical abuse and neglect increased over the study period and were associated with hospital volume and patient characteristics which may reflect provider experience and possible bias.

Factors associated with the interhospital transfer of emergency general surgery patients.
Researchers used data from the Nationwide Inpatient Sample to determine patient- and hospital-level factors associated with interhospital emergency general surgery (EGS) transfers. They identified that hospital-level characteristics more strongly predicted the need for transfer than patient-related factors. They recommended considering these factors in order to facilitate transfer decision-making.

Association between operating room access and mortality for life-threatening general surgery emergencies.
Few diseases truly require emergency surgery today. In this study, the authors investigated the relationship between access to operating room (OR) and outcomes for patients with life-threatening emergency general surgery (LT-EGS) diseases at US hospitals. The investigators concluded that round-the-clock availability of personnel, specifically emergency general surgeons and recovery room nurses, is associated with decreased mortality.
