Hematology in times of crisis: Lessons learned and strategic priorities from the EHA–ASH Joint Workshop on Ukraine

Armed conflict poses profound and sustained challenges to the delivery of hematological care, particularly for patients requiring complex diagnostics, multimodal therapies, and long-term followup.Children and adults with hematological malignancies and nonmalignant blood disorders are among the most vulnerable populations in humanitarian emergencies, as their care depends on uninterrupted access to specialized diagnostics, blood products, pharmacotherapy, cellular therapies, and highly trained multidisciplinary teams.Disruption at any point along this continuum can rapidly translate into increased morbidity and mortality.Since Russia's full-scale invasion of Ukraine in February 2022, the Ukrainian healthcare system has faced sustained pressure from direct attacks on healthcare infrastructure, population displacement, workforce shortages, supply chain disruptions, failing physical infrastructure (water, heating, and electricity), and financial instability.1,2 More than 2200 attacks on healthcare facilities have been reported till December 2025, alongside repeated interruptions to electricity, water supply, and the transport system. 3 Despite these challenges, the Ukrainian hematology community has demonstrated extraordinary resilience and adaptability, maintaining essential services while reorganizing care delivery under extreme constraints.With
