It is commonplace today to deplore the dissatisfaction of patients with the physician-patient relationship. Furthermore, historical investigation shows that this problem is not really new. We investigated an important source of patients' views in the 18th century, namely the letters of patients received by the famous Swiss physician, Samuel Tissot, and noted remarkably similar feelings of frust...

Managed care uses financial incentives and restrictions on tests and procedures to attempt to influence physician decision making and limit costs. Increasingly, the public is questioning whether physicians are truly making decisions based on the patient's best interest or are unduly influenced by economic incentives. These circumstances lead to the potential for disagreements and conflict in th...
