Discussion
Typical DTCA contains multiple messages about physician-patient communication. The primary way that DTCA may endorse a participatory model is via messages that encourage consumers to initiate conversations with physicians about products. About 70% of communication references explicitly direct consumers to do so. Otherwise, ads do not encourage consumers’ control. In fact, nearly 55% of communication references cast the physician in control, while only 15% placed the consumer in control. Thus, DTCA reinforces physicians’ relational control while encouraging consumers to initiate communication.
DTCA steers conversation topics toward products’ benefits and away from their deficits. Ads most often suggest products’ medical utility and appropriateness as topics (ie, general information, clinical judgments), while avoiding negative topics (ie, side effects, risks).
DTCA’s communication lessons for practice
Present results have implications for physician-patient interaction. First, to the extent that DTCA influences patients’ communication behavior, physicians increasingly may encounter patients who initiate communication by asking questions, often about advertised drugs. Some physicians may see such questions as requests or even demands for those drugs. Physicians report feeling pressure to prescribe products about which patients inquire;9 thus, patients merely asking more questions may be perceived as “demanding.”44
However, physicians often perceive “patient demand” when patients have not specifically asked for a drug.45 Physicians may want to check their perceptions before acting on them, recognizing that such questions may indicate patients’ preferences for a more participatory model, which, in turn, is associated with greater patient satisfaction.46,47 Physicians desiring to avoid conflict when patients ask questions might encourage their participation rather than assuming “patient demand” or feeling pressure to alter prescribing behavior.
Second, despite some physicians’ concerns, DTCA’s communication messages do not encourage patients to take relational control, nor do they undermine physicians’ prescribing authority. Theoretically and ethically, physicians remain in control of decisions, including prescribing, by serving as learned intermediaries or “conduits of information between manufacturers and patients.”48 Practically, physicians remain in control because their cooperation is necessary, even in cases where patients actively seek particular prescriptions.
Third, if DTCA influences patients’ choice of communication topics, patients may fail to inquire about drugs’ risks or side effects, a finding especially important in light of evidence indicating that consumers tend to not retain DTCA’s risk information.49 Physicians need to be alerted to these trends so they ensure that conversations with patients include explicit discussion of drugs’ side effects and risks.
Limitations
This study has several limitations. First, we analyzed print DTCA only. Generalizing findings to television and Internet DTCA may not be possible.
Second, our sample, dated from 1998 to 1999, may differ systematically from current ads. However, our study does provide a theoretically-driven methodology for assessing, and understanding the implications of, changes in advertising strategies across time and media.
Third, we analyzed marketing efforts targeting consumers. Physicians are exposed to numerous pharmaceutical marketing efforts that may contain messages regarding physician-patient communication.
Fourth, we limited analysis of relational communication to relational control; communication theory and research considers additional relational dimensions (eg, affiliation, trust) that likely influence the physician-patient relationship. Finally, we identified DTCA messages that may influence consumers’ behavior; we did not investigate actual behavioral changes associated with exposure to DTCA.
