Delays in the air or ground transfer of patients for endovascular thrombectomy.
This study’s objective was to examine associations between transfer time, modes of transfer, endovascular therapy (ET), and outcomes within a hub-and-spoke telestroke network. Results showed an association between longer transfer time and decreased likelihood of undergoing ET. Nocturnal transfers were associated with a substantial delay relative to daytime transfers. In contrast, delivery of tPA was not associated with delays, underscoring the impact of effective protocols at spoke hospitals. More efficient transfer may enable higher ET treatment rates.

Implementation of rapid treatment and interfacility transport for patients with suspected stroke by large-vessel occlusion: in one door and out the other.
This editorial discusses an article in this same issue of JAMA Neurology (McTaggart et al) that describes the results of the implementation of a standard protocol for patients with suspected emergent large-vessel occlusion (ELVO), and the protocol’s impact on both the process of care and patient outcomes. The editorial concludes that the McTaggart article challenges the medical community to develop an interdisciplinary, team-based, protocol-based approach to patients with potential ELVOs, and that work across the disciplines is needed to achieve an acceptable false-positive rate for the system.

Optimization modeling to maximize population access to comprehensive stroke centers.
This report demonstrates how mathematical optimization modeling can inform the strategic development of the US network of stroke centers by simulating the conversion of primary stroke centers into comprehensive stroke centers (CSCs). Optimal system simulation can be used to develop efficient care systems that maximize accessibility. Under optimal conditions, a large proportion of the US population will be unable to access a CSC within 60 minutes.
