Current Rural Stroke Management Guidelines
In rural settings, EMS should transport suspected stroke patients directly to a Comprehensive Stroke Center (CSC) or Thrombectomy-Capable Stroke Center (TSC) if reachable within 60 minutes total transport time; otherwise, transport to the nearest Acute Stroke Ready Hospital (ASRH) or Primary Stroke Center (PSC) that has telestroke capabilities and formal transfer agreements with regional advanced stroke centers. 1
Prehospital Transport Decision Algorithm
For Suspected Large Vessel Occlusion (LVO):
Direct to CSC if additional transport time beyond nearest TSC does not exceed 30 minutes AND maximum total transport time from scene to CSC does not exceed 60 minutes 1
Direct to TSC if no CSC within 60 minutes, provided additional transport time beyond nearest PSC/ASRH does not exceed 30 minutes AND maximum total transport time does not exceed 60 minutes 1
Transport to nearest ASRH or PSC if no CSC or TSC exists within 60 minutes of total travel time 1
For Patients Within IV Thrombolysis Window:
Prioritize nearest ASRH or PSC in rural areas without access to endovascular thrombectomy (EVT) centers within 60 minutes, as IV thrombolysis within 4.5 hours is critical 1, 2
EMS should use validated stroke scales (Cincinnati Prehospital Stroke Scale or Los Angeles Prehospital Stroke Screen) for recognition and assessment 1
Air Medical Transport Considerations
When no CSC or TSC is available within 60 minutes by ground transport, systems of care should include air medical transport options with defined maximum allowable transport times. 1 This is particularly relevant given the time-sensitive nature of stroke interventions and the potential for air transport to expand access to advanced care. 1
Rural Hospital Requirements
Essential Infrastructure:
Formal collaboration agreements with regional CSCs or TSCs for telestroke consultation access 1
Written transfer agreements with predetermined rapid escalation protocols 1
Dedicated stroke coordinator to support internal stroke resources 1
CT angiography capability when feasible (without significantly increasing door-in-door-out times) to identify LVO candidates and minimize overtriage costs during interfacility transfer 1, 3
Critical Protocol Elements:
Simultaneous notification of both the regional CSC/TSC partner and the EMS agency for interfacility transport when transfer is needed 1
Quality improvement processes such as Mission: Lifeline Stroke to optimize and monitor door-in-door-out (DIDO) times 1
Advanced Life Support (ALS) level or higher for interfacility transport when available 1
Immediate Management at Rural Facilities
Upon Patient Arrival:
Activate telestroke consultation immediately with regional tertiary center, which increases tPA treatment rates and reduces poor outcomes 2
Obtain non-contrast head CT immediately to differentiate ischemic from hemorrhagic stroke 2
Consider CT angiography to identify LVO candidates for thrombectomy 2
Pharmacological Interventions:
Administer IV thrombolysis (tPA) within 4.5 hours of last known well time if no contraindications 2
Administer aspirin 160-325mg for suspected ischemic stroke (after hemorrhage excluded) 2
All eligible patients should receive IV thrombolysis before transfer, as up to 75% of suspected LVO cases do not ultimately receive EVT at the regional center 1
Common Pitfalls to Avoid
Do not delay interfacility transfer to complete thrombolysis infusion in patients potentially eligible for EVT, except in exceptional circumstances—transport should occur without delay 1
Avoid bypassing rural hospitals unless specifically indicated by local EMS acute stroke triage algorithms and maximum allowable travel restrictions 1
Recognize that patients with suspected LVO beyond thrombolysis windows may require different destinations than those early in the ischemic window 1
EMS Training and Equipment Requirements
EMS personnel must demonstrate proficiency in stroke recognition, validated scale assessment, stabilization during transport, establishing time of onset, transporting patient medications, and effective communication with receiving facilities 1
High priority dispatch should be assigned to suspected stroke calls 1
EMS providers participating in interfacility transport should be trained and equipped for post-thrombolysis management 1
System-Level Quality Improvement
Rural hospitals should participate in regional stroke quality improvement programs with feedback mechanisms between EMS, rural hospitals, and regional stroke centers about acute stroke triage algorithms and destination plans 1
Seek certification as ASRH to track performance on evidence-based stroke care 1
Partner with regional CSCs to provide access to stroke research and quality improvement opportunities when feasible 1
