Secondary undertriage of pediatric trauma patients across the United States emergency departments.
The term “Undertriage” refers to the treatment of patients at facilities lacking in the equipment needed to treat the patient's injuries appropriately. The purpose of this retrospective cohort study was to assess the relationship between patient and hospital characteristics and secondary undertriage in children after major trauma. The researchers utilized the 2019 Nationwide Emergency Department Sample and included patients aged less than 18 years of age if they presented to a Level 3 or non-trauma center (NTC) and were diagnosed with a traumatic injury with an injury severity score of greater than 15 based on International Classification of Diseases 10 codes. The study found that of 6,572 weighted patients, 15% were undertriaged. Undertriage was significantly associated with older age, metropolitan location, and major abdominal injuries. After multivariable adjustment, secondary undertriage was significantly associated with patients aged 6-10 years of age compared to patients aged 15-17 years, penetrating injury, major chest injury, and presentation at a teaching hospital.

Critical revisits among children after emergency department discharge.
This retrospective study’s objectives were to determine the rate of critical emergency department (ED) revisits among children discharged from the ED and to identify factors associated with critical revisits. Using the HCUP State ED Databases (SEDD) and State Inpatient Databases (SID), researchers examined data from six states, including patients under 21 years old. The findings indicated that critical ED revisits after discharge were uncommon and patient death within three days of ED discharge were rare; patients with complex chronic conditions were more likely to have a critical ED revisit. The researchers concluded that future research should focus on understanding higher risk among patients with asthma or a history of complex chronic conditions.

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).

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.

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.

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.

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.

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.

Trend of age-adjusted rates of pediatric traumatic brain injury in U.S. emergency departments from 2006 to 2013.
The objective of this study was to use the 2006(-)2013 Nationwide Emergency Department Sample (NEDS) database to describe trends of age-adjusted rates of pediatric traumatic brain injuries (TBI) treated in U.S. emergency departments. The investigators found that the overall age-adjusted rates of pediatric TBI-related emergency department (ED) visits increased from 2006 to 2013, which was largely caused by pediatric mild TBIs, especially unspecified injury to the head (ICD-9-CM code 959.01) and concussion.

Cardiac arrest survival in pediatric and general emergency departments.
Understanding whether pediatric emergency departments (EDs) have higher survival than general EDs may help identify ways to improve care for all patients with out-of-hospital cardiac arrest (OHCA). Researchers sought to determine if OHCA survival differs between pediatric and general EDs. In their nationally representative sample, survival from nontraumatic OHCA was higher in pediatric EDs than general EDs. Survival did not differ in traumatic OHCA.

Why pediatric patients with cancer visit the emergency department: United States, 2006-2010.
The authors explored reasons prompting emergency department (ED) visits and factors associated with hospital admission among pediatric patients with cancer. They concluded that fever with neutropenia was the most common reason for ED visits among pediatric patients with cancer and was the condition most strongly associated with admission, and that socioeconomic factors appeared to influence ED disposition for this population.

Nationwide emergency department imaging practices for pediatric urolithiasis: room for improvement.
The researchers describe the national use of computed tomography (CT) versus ultrasound imaging for pediatric patients seen at emergency departments (EDs) for suspected urolithiasis (SU) during the period 2006-2010. Use of CT was much higher than use of ultrasound, although it dropped off after 2007. Lowest CT use was seen at EDs that care for more children.
