Introduction: Acute ischemic stroke (AIS) is thesecond leading cause of death globally, accounting for approximately 11% of alldeaths, long-term disability, and functional impairments in survivors. TheCOVID-19 pandemic has raised concerns about its impact on AIS patients. Aim: This study aimed to assess the outcomes,including mortality and severity of disability in AIS hospitalizations withCOVID-19.

Methods: We performed a retrospective cross-sectionalanalysis of the Nationwide Inpatient Sample (NIS-2020) in adulthospitalizations for AIS to compare the outcomes [death & APRDRGseverity/disability] in COVID-19 patients using ICD-10 codes. We performedweighted analyses using chi-square, unpaired t-test, and multivariate logisticregression models to evaluate COVID-19-associated poor outcomes amongst AISpatients.

Results: Out of 504,460 AIS patients, 7,590 had AIStriggered by COVID-19. Amongst AIS hospitalizations, COVID-19 was more frequentin age group >65 year old 63.2%, male 52.6%, White race (51.4%), patientwith Medicare (58.7%), median household income 0-25 percentile (33.6%), Southzone (43.4%), and hypertensives (83.7%). AIS patients with COVID-19 had ahigher mortality (10.93% vs 3.8%) and severe/extreme disability (93.21% vs37.43%) rates in comparison to patients without COVID-19. (p<0.0001) Inregression analysis COVID-19 was associated with 213% higher odds of mortality(aOR: 3.13, 95% CI: 2.90-3.38, p<0.0001, c:0.671) and higher odds of severe/extreme disability(26.85, 24.53-29.39, p<0.0001, c:0.686) compared to AIS patients withoutCOVID-19.

Conclusion: These findings emphasize the substantialimpact of COVID-19 on AIS patients by elevating mortality and risk of severedisability compared to their counterparts. Efforts should be directed towards earlyidentification of stroke population that is at higher risk ofCOVID-19-associated poor outcome and prompt management tomitigate the burden of the both diseases.
