Estimated population access to acute stroke and telestroke centers in the US, 2019.
In order to provide an update on population-level access to stroke care, the investigators estimated the proportion of the US population with access to an ED with acute stroke capabilities and assessed the specific contribution of telestroke services to US population access. They observed a substantial increase in population access to acute stroke care in this cross-sectional study relative to previous reports using alternative methods, likely due to the extensive and ongoing work to improve stroke systems of care, including greater stroke center accreditation and expansion of telestroke capacity.

Delay in emergency hernia surgery is associated with worse outcomes.
The purpose of this study was to determine if the variation in timing of urgent surgery impacts surgical outcomes. The National Surgical Quality Improvement Program (NSQIP) database was searched for emergent surgeries in 2011-2016 for abdominal hernia resulting in obstruction or gangrene by primary post-op diagnosis. Findings showed that delayed surgery was associated with increased rates of major complications, longer operative times, longer postoperative lengths of stay, increased re-operations, increased readmissions, and increased 30-day mortality. Next-day surgery and surgery delayed more than one day were associated with increased odds of a major complication.

Effect of acute stroke care regionalization on intravenous alteplase use in two urban counties.
Investigators sought to determine whether increasing access to primary stroke centers (regionalization) led to an increase in intravenous alteplase use in acute ischemic stroke patients. Studying two urban counties in the western region of US that regionalized acute stroke care, they found that in Santa Clara County, intravenous alteplase was administered to 1.7% of patients in the pre-regionalization period and 2.1% in the post-regionalization period, while in San Mateo County, the numbers were 1.3% and 3.2%, respectively. In the post-regionalization phase, San Mateo County had greater change in paramedic stroke detection, higher number of transports to primary stroke centers, and more frequent use of intravenous alteplase at stroke centers. They concluded that greater post-regionalization improvements in San Mateo County contributed to significantly improved county-level thrombolysis use than Santa Clara County.

A pilot study describing access to emergency care in two states using a model emergency care categorization system.
To improve regionalization of care and patient decisions when seeking emergency care, the researchers surveyed emergency departments (EDs) in 2 States. They found that 25 percent provided advanced care, 10.5 percent comprehensive care, and 1.6 percent pediatric critical care. Overall, 75.1 percent of the population could reach advanced or comprehensive ED within 60 minutes by ground transportation.
