Abstract The European Observatory on Health Systems and Policies has been working for more than 25 years on the systematic description, analysis and comparison of health systems in Europe. This workshop explores experiences so far with a new series of health system profiles, the Health Systems in Action (HSiA) Insights, launched in 2021 in collaboration with the WHO Regional Office for Europe. The first round of the Insights in 2021 was a pilot series, covering just five countries (Georgia, Kyrgyzstan, North Macedonia, Ukraine, and Uzbekistan). Since then, the series has grown to 13 countries in 2022 and in 2024 is covering almost all WHO Member States that are outside of the European Union (EU). The Insights aim to provide short and easily accessible documents that provide core information on a country’s health system, its key strengths and challenges, how it compares to other health systems in Europe, and how it impacts on the health of its population. This roundtable provides a platform for sharing experiences with devising, writing and using the series so far, bringing in country and comparative perspectives and involving the audience. The objectives of the roundtable are to a) identify best practices for the comparative description and analysis of health systems in the form of a series of country profiles; b) explore the challenges of drawing up country profiles where comparative data are lacking, incomplete or politicized; c) identify ways of disseminating and using country profiles; d) establish an opportunity for cross-country learning and skills development for the writing of health system descriptions and analyses. The roundtable will consist of four speakers. It will start with three very brief country presentations on the Insights for Israel, North Macedonia and Kazakhstan, followed by a brief comparative perspective on how to capture, compare and analyse health workforce trends across a broad set of countries, which is the Spotlight section of the 2024 round of Insights. This will be followed by a broad discussion with audience interventions to bring in the experience of other experts and countries. The moderated discussion will emphasise key learning points on how to devise a comparative series, how to write health system profiles and how best to use them to inform health policy-making. Key messages • The regular monitoring of health systems and policies is challenging, but essential for improving them. • Health system summaries require systematised approaches and up-to-date comparative data.
