COVID-19 and Stroke: Are Patients Hesitant to Seek Emergency Care?

During COVID-19 surges, stroke presentations dropped 30–40% globally—not because strokes decreased, but because patients delayed or avoided care. This "collateral damage" increased disability and death.

Barriers to Seeking Stroke Care

Barrier	Mechanism	Impact
Fear of COVID acquisition	Avoid ED/hospital perceived as infection hotspots	Delayed presentation beyond thrombolysis/thrombectomy windows
Symptom misattribution	Stroke signs (weakness, speech difficulty) confused with COVID fatigue, neuropathy	Failure to recognize BEFAST symptoms
Transport disruption	Reduced EMS availability, public transit cuts, ride-share reluctance	Longer pre-hospital times
Healthcare strain	ED boarding, ICU diversion, staff shortages	Perceived futility; actual delays in imaging/treatment
Reduced public awareness	Campaigns paused; media dominated by COVID	Lower BEFAST recognition

Consequences of Delay

• IV tPA window: ≤4.5 hr (≤3 hr for some).
• Mechanical thrombectomy: ≤24 hr for selected LVO (DAWN/DEFUSE-3 criteria).
• Every 15-min delay → 4% relative reduction in good outcome (IST-3).
• Data: increased in-hospital mortality, worse mRS scores, more severe deficits during pandemic.

Mitigation Strategies

Public Education

• BEFAST campaigns: Balance, Eyes, Face, Arm, Speech, Time.
• Explicit messaging: "Stroke doesn't wait for COVID. Call 911."
• Multilingual, culturally tailored materials.

Telemedicine Triage

• Telestroke networks: remote neurologist assessment → tPA decision → transfer if needed.
• EMS telehealth: paramedic video consult en route.

System-Level Protections

• Stroke pathways preserved: dedicated CT, tPA stock, thrombectomy-capable centers on diversion protocols.
• COVID/non-COVID care zones; universal masking; rapid testing.
• Pre-notification by EMS → stroke team ready.

EMS & Community Partnerships

• EMS education: stroke severity scales (RACE, VAN) for direct transport to comprehensive centers.
• Community health workers: check on high-risk (AFib, prior stroke) during surges.

Post-Pandemic Imperative

• Embed stroke readiness in all-hazards planning.
• Sustain tele-stroke infrastructure.
• Address health equity: disparities in stroke care access widened during pandemic.
• Monitor "missing strokes" via population surveillance.

Time is brain — always. Pandemic or not, stroke is a 911 emergency.
