Dagenais, C. /Ridde, Valéry health policies administration knowledge translation evaluation knowledge brokering Introduction: Reducing social health inequalities requires bridging the gap between knowledge and its implementation. Knowledge brokering facilitates exchanges between researchers and practitioners but remains underexplored in the French public health system. Methods: This study evaluates a knowledge brokering intervention within the Ile-de-France Regional Health Agency (ARS). The intervention aimed to strengthen staff capacities through knowledge translation activities, including training sessions and thematic groups. A qualitative evaluation was conducted based on participant observations and 16 semi-structured interviews. Data were analyzed both inductively and deductively using a coding framework focused on effectiveness, implementation, and influencing factors. Results: The intervention was well received, supported by strong institutional leadership and motivated stakeholders. However, participation remained limited due to time constraints, a lack of clarity regarding the role of brokers, and difficulties integrating the intervention into existing mechanisms. While thematic groups and the MOOC helped strengthen staff knowledge and skills, their impact on decision-making was modest, and dissemination across the different departments of the Regional Health Agency was limited. Discussion: The evaluation prompted adjustments in the intervention and highlighted the need to redefine the knowledge brok-ering function to better fit this context-for example, by estab-lishing brokering as a dedicated unit. 2026 text https://www.documentation.ird.fr/hor/fdi:010097021 fdi:010097021 Fillol Amandine, Traverson Lola, Zitti T., Bars G., Minssieux N., Hot A., Dagenais C., Ridde Valéry.
