Despite basing its foundation upon the ideals of Hippocrates, Western medicine, especially in the last century, has shifted from a holistic to a more reductionist approach to understanding and treating patients. These changes are primarily a result of widespread acceptance of the biomedical model in modern medicine. Consequently, there are now significant differences in physician and patient explanatory models for the same ailment. Cancer, for example, is interpreted as primarily a physiological process by the medical community, or more simply, as a disease. The patient, on the other hand, interprets cancer as an illness, a more subjective response, covering all aspects of the patient’s life experience, including emotional, psychological, social, and cultural realms, in addition to physiological aspects. These differences in explanatory models result in disparities between physicians and patients when it comes to defining the condition, managing the condition and even defining successful outcomes. These incongruencies must be addressed through effective communication in the clinical encounter, an aspect of patient care that has proven beneficial effects on patient health outcomes. The shared treatment decision-making model best addresses these communication problems. By providing a framework for both the physician and patient to negotiate their respective explanatory models en route to a mutually agreeable treatment decision, this model is a compromise between the two extremes of patient-physician models of communication: paternalism andinformed decision-making. Ultimately, the shared treatment decision-making model establishes a clinical relationship that is no longer characterized by an inabilityto effectively negotiate and consolidate differing values due to unbalanced informational and power dynamics in a social context. By incorporating this model of communication into medical practice, physicians and patients will better understand each other, bridging the disparities apparent in current practice and allow Western medicine to once again approximate the Hippocratic ideal.
