Abstract Person-centered, multidisciplinary care is key to addressing evolving complex health needs. In Estonia, Latvia, and Lithuania, this pursuit of integrated care has gained momentum as an innovative approach to allocate resources more efficiently and improve patient outcomes. This study investigates the progress of integrating care in the Baltic countries from 2019 to 2024. It details key learnings, particularly for small European countries with limited resources. The Health Systems and Policy Monitor Network of the European Observatory on Health Systems and Policies undertook a cross-country study to better understand the progress in care integration in the Baltics. The Network’s Baltic country experts completed a 21-item questionnaire on the adoption of integrated care reforms. Responses were analyzed to capture reform characteristics and commonalities, countries’ political environments and their conduciveness to the uptake of integrated care. Country-specific experiences with the implementation of integrated care were further explored via case studies of pilot programs over the five years. The pace of implementing integrating care reforms varied in each country. Existing regulatory barriers, workforce challenges and payment schemes have impeded integration efforts across health and social care. Despite these obstacles, the political commitment to new and innovative service delivery and collaboration for chronic care management underscores an important prerequisite toward achieving more integrated and person-centered healthcare. The three case studies illustrate the hurdles that come with shifting care settings and expanding roles for some workers. Findings stress the role for integrated care to address organisational challenges in the Baltics. This study highlights innovative approaches and long-running efforts to provide multidisciplinary care for complex-needs patients and the implications of their results for broader health system adoption. Key messages • Small countries like the Baltics face structural challenges in integrating care to improve outcomes and efficiency. • Investment and innovative care approaches are key to further advancements.
