Aim 1: Compare the proportion of patients encountered by the emergency medical service (EMS) with suspected large vessel occlusion (LVO) before and after implementation of TCC coordinated SBST
The investigators will compare the proportion of patients encountered by the Emergency Medical Service (EMS) with suspected large vessel occlusion who are treated with mechanical thrombectomy before (adhering to standard triage to the nearest stroke center) and after implementation of Trauma Communications Center coordinated Severity-Based Stroke Triage.
Aim 2: Assess the public health impact of TCC coordinated SBST by using the RE-AIM framework
The investigators will compare the public health impact using the RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) framework before (adhering to standard triage to the nearest stroke center) and after implementation of Trauma Communications Center coordinated Severity-Based Stroke Triage.
Aim 3: Assess stakeholder perceptions of the intervention’s feasibility, appropriateness, and acceptability and identify the barriers
Using a mixed methods approach, the investigators will survey stakeholders (Trauma Communications Center, Emergency Medical Service Regional Advisory Councils, Emergency Medical Service, and stroke center directors and stroke coordinators) to assess perceptions of Acceptability of Intervention Measure (AIM), Intervention Appropriateness Measure (IAM), and Feasibility of Intervention Measure (FIM). The investigators will conduct follow-up qualitative interviews with purposefully selected individuals to identify barriers and facilitators to adoption, implementation, maintenance, and spread of the intervention.
