National assessment of clinicians participating in stroke treatment decisions at strokenet regional coordinating centers

Objectives

Since the introduction of thrombolytics, stroke teams evolved to improve thrombolytic care delivery. The impact of the advent of endovascular therapy on the composition of acute stroke teams is unknown.

Materials and Methods

A two-part pilot-tested survey was deployed to site-Principal Investigators (PIs) of the 27 StrokeNet Regional Coordinating Centers (RCCs) regarding institutional acute stroke teams. Part A inquired about the participation of personnel in each type of stroke response. Part B identified stroke team physicians and the types of responses in which they participate to assess training background of stroke team members.

Results

Response rates for Part A and B were 66% and 48%, respectively. In Part A, 67% (12/18) of sites reported trainees always responded to ED stroke activations with significant autonomy. 44% (7/16) and 27% (4/15) of sites reported NP and PA response to ED stroke alerts, respectively, but with limited autonomy. In Part B, 124 physicians involved in ED stroke alerts were identified, the large majority of whom (79%, 95% CI: 71-85) were vascular neurology trained. The 39 (23%) stroke team members involved in endovascular therapy had the following training: 49% (34-64) neurosurgery, 28% (17-44) radiology, 18% (9-33) vascular neurology 5% (1-16) neurology.

Conclusions

We identified modest heterogeneity in the composition of acute stroke team members across StrokeNet RCCs. Individuals performing endovascular therapy had a variety of clinical specializations, reflecting the evolving multidisciplinary nature of interventional acute stroke care. At StrokeNet RCCs, teams have significant trainee involvement in both ED and inpatient acute stroke responses.
