Abstract Health systems all over the world are struggling to meet population health needs and provide timely access to universal healthcare in the context of the COVID-19 pandemic. COVID-19 occurred in Ireland in the early years of implementation of a national plan for universal healthcare, called Sláintecare. While many health systems are experiencing a retrenchment on universalism in the context of COVID-19, in Ireland despite tediously slow Sláintecare implementation, the pandemic provided a boost to reform implementation and universalism. The reason for this workshop is to draw on a publicly funded Health Research Board Applied Partnership Award, entitled ‘Foundations’, harnessing lessons from the Irish COVID-19 health system response to inform Sláintecare’s implementation https://hrbopenresearch.org/articles/3-70/v1 The objectives of the workshop are to 1) provide academic research evidence from the Irish experience of universal health system reform during and since COVID-19; 2) to give participants space to reflect on the implications of the Irish universal health system reform on international health systems and policy; 3) to actively involve workshop participants in an engaged discussion on implementing universal health coverage in the context of COVID-19. The added value of the workshop is to share learnings from an academic research programme, which is coproducing evidence in partnership with the Irish health system, in a worldwide context, providing relevant and thought-provoking discussion and analysis for an international audience. Four separate inter-related presentations will draw on aspects of the Foundations’ research project. Presentation 1, Prof Sara Burke will outline recent academic literature on universalism and the politics of reform implementation in the context of COVID-19 and present a timeline of universal healthcare reform implementation since 2018 when Sláintecare was adopted by the Irish government (14 mins). Presentation 2, Dr Sarah Parker will detail a specific study which set out to advance understanding of how and to what extent COVID-19 has highlighted opportunities for change that enabled better access to universal, integrated care in Ireland, with a view to informing universal health system reform and implementation (10 mins). Presentation 3, Dr Katharine Schulmann and Carlos Bruen will present findings on the governance of reform implementation and implications for all health systems (10 mins). Presentation 4, Dr Philip Crowley, Health Service Executive (HSE) National Director of Strategy and Research and Chair of the Foundations’ research steering group will reflect how research findings can inform implementing reform and their implications for all health systems (6 mins). There will be four presentations totalling 40 mins, followed by questions and discussion chaired by an international expert/academic on universal health systems. Key messages • COVID-10 has highlighted how universal health coverage is more important than ever, however the pandemic has resulted in some retrenchment on universalism. • While data and research drove health system decision making during the pandemic, embedding research evidence into health system and policy reform remains challenging and can be politically opposed.
