Socioeconomic inequalities in health and health care are important challenges for public health. In terms of health inequalities, Lithuania is among the most unfavourable countries in the European Union. In 2014, the Lithuanian Parliament approved its "Health Programme 2014-2025". One strategic goal of this programme is to reduce health and health care inequalities in Lithuania. The purpose of the project was to develop an evidence-based platform for health and health care inequalities to monitor and strengthen the administrative capacities of personnel involved in policy making at national and municipal levels. It included four main actions: 1) analysis of the present situation in monitoring and reducing health inequalities; 2) development of a sustainable health inequalities monitoring system; 3) development of a set of recommendations for public health professionals for health inequalities reduction; and 4) capacity development of public health professionals and health policy makers in the area of health inequalities. We expect that recommendations coming from this project will contribute to change practices in the target groups, thereby improving public health and reducing health and health care inequalities in Lithuania. Moreover, this model could serve as an example relevant for other countries confronted with the task of tackling health inequalities.
