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.
