Patient proactivity enhancing doctor-patient-family communication in cancer prevention and care among the aged.

This paper presents a comprehensive conceptual model of health care communication involving three key health care partners: patients, physicians, and significant family members (health significant other, HSOs). A unique feature of this model is its focus on proactive roles played by elderly patients in information gathering and communication with health care partners regarding both cancer prevention and cancer care. We outline how proactive initiatives by health care consumers and involvement of their HSOs can enhance patient outcomes (satisfaction with physician, adherence to preventive and corrective practice recommendations, and quality of life). Finally, we also note primary antecedents of health care partner communication in terms of both medical care context and patient characteristics. We hope that this testable causal model will inform future research in the field of health communication.
