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.

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%.

Racial disparities in utilization of palliative care among patients admitted with advanced solid organ malignancies.
The primary objective of this study was to describe racial differences in the use of inpatient palliative care consultations (IPCC) for patients with advanced cancer who are admitted to a hospital in the United States. Hospital admissions of patients with advanced cancers were identified through the National Inpatient Dataset. Findings showed that death during hospitalization was a significant modifier of the relationship between race and receipt of palliative care consultation. There were significant racial disparities in the utilization of IPCC for patients with advanced cancer.

Increased utilization of total joint arthroplasty after Medicaid expansion.
This study examined prior analyses that greater utilization of total hip arthroplasty (THA) and total knee arthroplasty (TKA) was to be expected after Medicaid expansion in 2014. Using 2012-2015 data from the HCUP Database, 9 expansion states (Arkansas, Arizona, Colorado, Iowa, Massachusetts, Maryland, Nevada, New York, and Vermont) were compared to 2 states that did not expand Medicaid (Florida and Missouri). After adjusting for community characteristics, THA and TKA increased 15% in 2014 and 23% in 2015 within expansion states compared to 2013. In non-expansion states, compared to 2013, there were significant decreases of 18% in 2014 and 11% in 2015.

The relationship between local economic conditions and acute myocardial infarction hospital utilization by adults and seniors in the United States, 1995-2011.
The researchers assessed the association between unemployment and hospital discharges for acute myocardial infarction (AMI) among adults and seniors, 1995–2011. They found that for both adults and seniors, a 1 percent increase in the unemployment rate was associated with a statistically significant decline in AMI hospitalization during the first half of the study but was unrelated to the economic cycle in the second half of the study period.

Trends in tracheostomy for mechanically ventilated patients in the United States, 1993-2012.
This study investigated trends in tracheostomy use, timing, and outcomes in the United States. It found that over the past two decades, tracheostomy use rose substantially in the United States until 2008, when use began to decline. In addition, there was an observed dramatic increase in discharge of tracheostomy patients to long-term care facilities.

Emergency department use in the US-Mexico border region and violence in Mexico: is there a relationship?
This study assessed the association between homicide rates in northern Mexico and potentially avoidable use of emergency departments (ED) in the US-Mexico border region. It concluded that a substantial majority of ED encounters in the US-Mexico border region were potentially avoidable. However, there was not a strong relationship between homicide rates in northern Mexico and the distribution of ED discharges in Arizona and California.

National trends in the use of postcardiac arrest therapeutic hypothermia and hospital factors influencing its use.
The goal of this study is to use population-based national hospital discharge data to examine trends in the use of therapeutic hypothermia (TH) in both in- and out-of-hospital cardiac arrest patients after implementation of the 2005 American Heart Association guidelines. Its findings demonstrate that while TH use is increasing, the overall utilization of TH relative to all cardiac arrests remains very low.
