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.

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.
