Article Abstract
Background: Lack of high-quality national-level data on in-hospital ischaemic stroke hinders the development of tailored strategies for this subgroup's identification, treatment, and management.
Methods: We analyzed and compared clinical characteristics, in-hospital management measures, and outcomes, including death or discharge against medical advice (DAMA), major adverse cardiovascular events (MACEs), disability at discharge, and in-hospital complications between in-hospital and community-onset ischaemic stroke enrolled in the Chinese Stroke Center Association registry from August 2015 to December 2022.
Findings: The cohort comprised 14,948 in-hospital and 1,366,898 community-onset ischaemic stroke patients. In-hospital ischaemic stroke exhibited greater stroke severity, higher prevalence of comorbidities, more pre-admission medications, and had suboptimal management measures, for example, the onset-to-needle time within 4.5 h (83.3% vs. 93.1%; difference, -9.8% [-11.4% to -8.3%]), and antithrombotics at discharge (78.6% vs. 90.0%; difference, -11.4% [95% CI, -12.1% to -10.7%]). After adjusting for covariates, in-hospital ischaemic stroke remains associated with higher risks of unfavorable outcomes, including in-hospital death/DAMA (13.9% vs. 8.6%; adjusted risk difference [aRD], 2.2% [95% CI, 1.8%-2.7%]; adjusted odds ratio [aOR], 1.35 [95% CI, 1.25-1.45]), MACE (12.6% vs. 6.5%; aRD, 4.1% [95% CI, 3.5%-4.7%]; aOR, 1.68 [95% CI, 1.52-1.85]), and complications (23.7% vs. 12.1%; aRD, 6.5% [95% CI, 5.1%-7.9%]; aOR, 1.72 [95% CI, 1.64-1.80]), except for disability at discharge (41.1% vs. 33.1%; aRD, 0.4% [95% CI, -1.7% to 2.5%]; aOR, 0.99 [95% CI, 0.88-1.11]).
Interpretation: In-hospital ischaemic stroke demonstrated more severe strokes, worse vascular risk profiles, suboptimal management measures, and worse outcomes compared to community-onset ischaemic stroke. This emphasizes the urgent need for improved hospital systems of care and targeted quality improvement initiatives for better outcomes in in-hospital ischaemic stroke.
