How COVID-19 Disrupted Global Stroke Care and Worsened Patient Outcomes
Global stroke care suffered disruptions during the COVID-19 pandemic, as patient hesitation, hospital strains, and shifting emergency protocols delayed critical treatments and worsened patient outcomes worldwide. According to a scoping review published in BMC Health Services Research by Ménard and colleagues, these systemic failures spanned 107 studies examining evidence from December 2019 through September 2024, revealing that fear of infection and overwhelmed healthcare facilities caused dramatic drops in monthly stroke admissions alongside sharp spikes in disease severity at the time of hospital presentation.
- Monthly ischaemic stroke admissions dropped significantly during the pandemic, with individual studies reporting declines of 31% to 44%.
- Patients who did reach hospitals often presented with more severe strokes and experienced poorer recovery outcomes, including higher disability scores at discharge and 3-month follow-ups.
- In-hospital mortality rates climbed notably among pandemic-era cohorts, rising to 7.7% compared with 2.5% in pre-pandemic groups according to analyzed analyses.
Pandemic Fear and Access Barriers Delay Stroke Presentations
As the pandemic unfolded, public health systems confronted an immediate behavioral shift among patients experiencing acute neurological symptoms. The scoping review analyzed evidence showing that many individuals delayed seeking emergency medical attention because they feared contracting COVID-19 in hospital settings or perceived that emergency services were overwhelmed. These behavioral barriers were especially pronounced among patients with milder symptoms, causing them to miss critical therapeutic windows for time-sensitive interventions like thrombolysis and thrombectomy.
While the rapid adoption of telemedicine helped maintain some continuity of care for younger populations, lower remote service utilization among older adults highlighted persistent equity gaps in digital healthcare access. Parallel findings from a systematic review published in BMJ Open by researchers examining populations aged 65 and older demonstrated that 84% of included studies reported decreased hospital admission rates during the pandemic. That review noted that while minor strokes went unmanaged at home, patients arriving at emergency departments frequently presented with advanced disease progression.
Pathobiological Vulnerabilities and Systemic Pressures
Beyond behavioral delays, researchers sought to understand the underlying biological and operational factors compounding stroke risks during the global health crisis. The review discussed how SARS-CoV-2 invades host target cells by utilizing viral surface spike proteins to bind with angiotensin-converting enzyme 2 (ACE2) receptors. This biological interaction can induce new cerebrovascular pathologies—including primary vasculitis, hypercoagulable states, cardiomyopathy, and endothelial dysfunction—that elevate the risk of systemic embolism and local thrombosis.
Compounding these pathobiological risks, healthcare facilities faced severe resource reallocation, workforce shortages, and modified clinical pathways. The BMJ Open review reported that altered in-hospital protocols led to increased treatment times in 60% of studies and a doubling of in-hospital mortality across 82% of the analyzed papers. Discharge data underscored the long-term toll of these systemic delays: patients treated during the pandemic exhibited a median modified Rankin Scale disability score of 4, compared to a median score of 2 prior to 2020, with these functional deficits persisting three months post-stroke.
Future emergency preparedness frameworks must prioritize adaptable stroke care pathways, comprehensive patient education campaigns, and equitable digital health access to safeguard vulnerable populations against future public health shocks.
