ABSTRACT NUMBER: ESOC2026YS118 TIMELINESS OF ACUTE ISCHAEMIC STROKE CARE: INSIGHTS FROM THE REGISTRY OF STROKE QUALITY CARE (RES-Q) AT A VIETNAMESE STROKE CENTRE

Abstract Background and aims Timely acute care is critical for reducing stroke-related mortality and morbidity. This study aims to describe factors associated with the timeliness of acute ischaemic stroke(AIS) care. Methods A retrospective analysis was conducted using data from AIS patients recorded in the Registry of Stroke Care Quality (RES-Q) from 2017 to 2023 at the Bach Mai Hospital Stroke Centre, Vietnam. AIS care timeliness was evaluated from 2022 to 2023. Outcomes were timely arrival (onset-to-door ≤4.5 hours), thrombolysis (door-to-needle ≤60 minutes), and thrombectomy (door-to-groin ≤90 minutes). Multivariable logistic regression models were utilised to identify factors associated with AIS care timeliness. Results A total of 7,909 AIS patients were included (median age: 66 years; 62.9% male). The median (IQR) times in minutes were 293 (165–685) for onset-to-door, 40 (27–53) for door-to-needle, and 87 (70–110) for door-to-groin. Only 39.5% of patients arrived timely. Among patients who received thrombolysis and thrombectomy, 90% and 54% of them received timely treatments, respectively. Factors associated with timely arrival were higher stroke severity, EMS use, previous stroke, and atrial fibrillation. Hypertension, referrals from another hospital, and stroke units reduced the odds of timely arrival. A timely arrival increased the odds of receiving timely treatments. Male gender and referrals from another hospital increased the odds of timely thrombolysis, whereas hypertension reduced the odds of timely thrombectomy. Conclusion: Despite strong in-hospital performance, delayed arrival remains a challenge to timely stroke care. Efforts should focus on improving both prehospital and in-hospital care to improve outcomes throughout the stroke care continuum.
