The gathering, analysis and publication of information about health is intended to aid decision-making for the various actors involved in Brussels health policies (politicians, professionals, associations, etc.)

As part of this work, the Observatory lends its expertise to actors through various activities: presentations, responses to specific questions, active participation in study days or meetings, sitting on a research support committee, participation in various working groups. In its role as a research centre for the Joint Community Commission, the Observatory actively participates as technical representative for Brussels in several working groups of the Inter-ministerial Health Conference.
