Taking care of a critically-ill patient is of high complexity level, as it includes bio-pschosocial and cultural aspects. Until recently, physicians have paid little attention to spirituality, although it constitutes the essential of human being. Spiritual need may reveal to be of utmost importance and has influence on bio-psycho-social aspects for a patient experiencing severe disease with threatening outcome and near death. A physician may transfer the problem to a specialist, a chaplain, or may personally be able to assess this need.

Their educational programs should include spirituality care training. Swiss intensivists should acquire the competency to take care of their patients in a holistic manner.
