Abstract
Professional autonomy interferes at a structural level with the various aspects of the health care system. The health care systems that can be distinguished all feature a specific design of professional autonomy, but experience their own governance problems. Empirical health care systems in the West are a nationally coloured blend of ideal type healthcare systems. From a normative perspective, the optimal health care system should consist of elements of all the ideal types. A workable optimum taking national values into account could be attained by governance structures that also introduce elements from other ideal type systems. Thus a normative approach to medical practice guaranteeing an essential degree of professional autonomy for a relationship of trust between the patient and the physician, could be combined with an efficient and equitable allocation of health care resources.
