Decision tree model describing alternate health care choices made by oncology patients.

What common sense decision strategies do patients with cancer use when they are making health care choices that include alternate therapies? Existing research indicates that oncology patients are making alternate choices while associated with biomedicine. Often patients' decision strategies are exploited by the alternate system to promote and market alternate products. Although some of these practices are benign, others are dangerous or may interfere or delay successful treatment in biomedicine. Therefore, it seems important for biomedical professionals to understand patients' common sense decision patterns. A decision tree model, outlining patients' decision strategies, has recently been developed through intensive interviews with 300 patients who were diagnosed with cancer of the respiratory and digestive systems. The two-phase methodology included, first, a context sensitive approach to develop the model, followed by a predictive approach testing the model developed in the first phase on a separate yet similar random sample of patients. The discussion in this article focuses on the research, the patterns of the decision tree model, and the implications and adaptability of this model to nursing practice.
