At the intersection of micro and macro: opportunities and challenges for physician-patient communication research.

The health care relationship model is undergoing dramatic change. Micro-level communication patterns yield health care relationship models (e.g. paternalism, mutual participation, consumerism). At the same time, macro-level systems appear increasingly likely to influence the nature of micro-level interaction. The intersections of health care communication micro-level and macro-level phenomena provide important venues for research and interventions. This essay identifies theoretical premises regarding the relationships between communication and health-related behavior; explores three prominent and growing macro-level phenomena that observers argue likely influence the physical-patient relationship and communication therein: complementary and alternative medicine, the Internet, and direct-to-consumer advertising of prescription drugs; and offers a research agenda for exploring macro-level influences on micro-level physician-patient communication.
