Decision-making models in Japanese psychiatry: transitions from passive to active patterns.

This study deconstructs the current dynamics of the physician-patient relationship in the treatment of minor mood disorders including depression in Japan. An in-depth qualitative investigation was conducted on psychiatrists employed at mental health clinics, university hospitals, and psychiatric hospitals. Triangulation was conducted concurrently using key informant interviews and periodic non-structured interviews with additional physicians and patients. Results revealed two patterns of omakase (entrusting) (Omakase Model) and an emerging pattern of patient participation in decision making (Participatory Model). The pattern traditionally denoted by the Omakase Model encompasses an active and passive entrusting model. The phenomenon of an emerging Participatory Model was uncovered whereby an in-depth analysis led to an understanding behind the associative physician-patient relationship, communication patterns, and a patient's level of awareness. It was found that while active participation in medical decision making is capable of raising the level of treatment efficacy, it is not only active participation in medical decision making, but also active participation in medical treatment that is valued in the physician-patient relationship. Ultimately, a patient actively participates in his or her medical treatment under either the active Omakase Model or Participatory Model, be it entrusting or participatory. Consequently, the active Omakase Model will continue to remain functional alongside the Participatory Model while the passive Omakase Model is likely to fade away in time. Copyright 2003 Elsevier Ltd.
