Although some clinicians are extraordinarily sensitive to the legitimate roles of patients'families in medical crises, a persistent tendency to equate families with trouble is evident in both the literature and the practice of medicine.

Some negative presumptions about families derive from western medicine's almost exclusive focus on the individual patient in codes of ethics, training, and practice.

Modern bioethics has reinforced this individualistic approach.

Physicians'primary responsibilities are unequivocally to their patients, but a complete understanding of the patient's personhood must include consideration of the significant persons who help define the patient's core identity.

One source of tension between professionals and families lies in differing perceptions of the roles that family members should play and how they should play them.
