40 preferably an international level try, first, to reach agreement on a core set of knowledge tools; second, to reach consensus on the definitions and terms used for these tools; and third, to develop a conceptual framework showing the relations between the tools. This tool issue seems to be an exemplification of the tenet that ‘less is more’. However, as we did not systematically invest Dutch clinicians’ and/or patients’ views on this issue, we would recommend that follow-up research is carried out to find out if Dutch healthcare professionals and patients are aware of the multitude of tool types, how they perceive this availability and how they deal with it. Another paper features our report on a Delphi process intended to reach a consensus on the number of tool types and their definitions at a national level in the Netherlands. This Delphi process (2015) was followed by an invitational meeting with international experts (2016) aiming to develop a framework of related knowledge tools, their purposes and characteristics (142).
