Cross-national differences in stroke management in the Baltic states: analysis within the Stroke Action Plan for Europe framework

INTRODUCTION: Although epidemiological studies often group the Baltic states together, they differ significantly in national stroke care legislation and infrastructure. Our study aimed to explore and compare the current state of stroke care in Lithuania, Latvia and Estonia. PATIENTS AND METHODS: We analysed the Stroke Action Plan for Europe (SAP-E) Stroke Service Tracker data from 2022, including data from the respective National Health Insurance Funds and direct centre-level queries. Geographic Information System-based modelling assessed population access to stroke-ready hospitals within 1 h. Key metrics, including hospitalised stroke incidence, stroke unit admission, recanalisation therapy and in-hospital as well as 30-day mortality, were compared using Z-tests for proportions. RESULTS: The hospitalised stroke incidence per 100,000 inhabitants was similar in Lithuania (353) and Latvia (354), but lower in Estonia (246), despite similar population structures. Lithuania had the highest proportion of its population (94.0%) with access to a stroke-ready hospital within 1 h, followed by Latvia (87.1%) and Estonia (84.7%, P < .001). Estonia had the highest proportion of stroke unit admission rates and the lowest mortality rates-9.6% (in-hospital) and 15.0% (30-day) for ischaemic stroke. Endovascular treatment was most frequent in Lithuania (8.6% of all strokes, P < .001), while Estonia had the highest rate of intravenous thrombolysis (29.0%, P < .001). CONCLUSIONS: Despite broadly comparable populations and formal SAP-E alignment, the Baltic states exhibit marked differences in stroke access, treatment and outcomes. High stroke unit admissions and high recanalisation rates in Estonia may be associated with lower ischaemic stroke mortality, underscoring the importance of system design beyond geographic coverage alone.
