[Interdisciplinarity in the hospital setting: between daily challenge and group stakes].

Group functioning may limit interdisciplinarity. Four scenarios of health professionals' meetings are described. A) If priority is timing, the group isn't interdisciplinary any longer; decisions are endorsed without questioning or criticism. B) When positions' stakes aren't clarified, speaking helps active persons to take power and passive ones to strengthen their criticisms. C) If caregivers are turned to their duties and territory, recourse to interdisciplinary process is only made in case of difficulties. D) When the group is moved by implicit standards, resources are underutilized. In conclusion, added value of interdisciplinary work is superior when divergent options are brought without influence of recurring problems or protocols.
