We applied Health Consensus, a web-based collective intelligence tool inspired by the Delphi method, previously tested in technological innovation processes (Monguet et al, 2010). Health consensus introduces a breakthrough in health policy participation, allowing thousands of participants to come along regardless of geographic and professional limitations. It also allows a qualitative participation through a transparent and instant participation outcome feedback as it has been proven to be an effective design (Edelenbos, 1999; Buur et al, 2013). A total of 3616 healthcare professionals took part in the collective health policy making. To analyse results, we applied a participation quality filter to take into account only the 1217 participants that successfully fulfilled the entire set of process requirements ; Postprint (published version)
