Pharmaceutical companies and their representatives attempt to influence the practice of medicine by giving gifts. Gifts, even those of trivial monetary value, impart a sense of obligation that conflicts with the provider's primary responsibility to the patient. Providers are less likely than their patients and peers to believe that gifts change their own prescribing habits, making them vulnerable to manipulation by industry. Providers who interact with drug reps must exercise caution to prevent compromise of the patient-physician relationship.
The pharmaceutical industry is one of the most profitable in the US . A distinctive feature of this business is its dependence on physicians to recommend its prescription products. This necessity is underscored by the promotional budget of pharmaceutical companies, over $27 billion in 2004, mostly targeted at physicians .
Gift giving is one way in which pharmaceutical companies and their representatives attempt to influence the practice of medicine. The impact of pharmaceutical representatives and gifts such as free lunches are increasingly popular topics in both the lay press and medical literature [2, 3, 4, 5]. Fearing a conflict of interest, medical professional societies have established guidelines to help healthcare providers decide which gifts are appropriate [6, 7]. Guidelines for the American Academy of Dermatology refer to those of the American Medical Association (AMA) . The AMA guidelines are somewhat vague, for example, stating that gifts should be "of minimal value." An attempt to clarify the guidelines set limits on gift value, such as $100, that seem arbitrary .
Moreover, such limits ignore the importance of small gifts. Studies reveal that seemingly insignificant gifts can influence behavior. For example, a pharmacy that gave a keychain to all patrons noted a 17 percent increase in sales . A charity fundraiser that employed direct mail solicitation had an increase in response rate from 18 percent to 35 percent when free address labels were included . Gifts, even those of trivial monetary value, impart a sense of obligation that conflicts with the provider's primary responsibility to the patient. A physician who is the recipient of a gift may recommend products made by the gift-giver without due consideration of other cheaper or more effective options.
This potential conflict of interest is not lost on patients. Although physicians may balk at the suggestion that their integrity is compromised by the acceptance of trinkets such as pens and notepads, a third of patients surveyed believe that the receipt of any gift compels a physician to prescribe a particular product . For all types of gifts except drug samples, patients are consistently more likely than physicians to think the gift is influential . This could compromise trust in the physician-patient relationship, whether or not the gift ultimately influences the physician. Furthermore, time constraints of typical patient encounters dictate that most physicians are unlikely to disclose all drug company-related gifts to their patients.
|Perceived influence of pharmaceutical representatives on prescribing practices. Percentage of residents (n = 102) who believe that pharmaceutical representatives influence the prescribing practices of other physicians (dark bars) and influence their own prescribing practices (light bars). Residents perceive themselves as less prone to influence than are other physicians (p < 0.0001 by McNemar's chi-square test). Reproduced from Steinman et al. , with permission from author.|
Providers perceive that drug companies successfully manipulate practices of other practitioners, yet deny that the companies' promotional efforts impact themselves (Fig. 1). Although 33 percent of medicine residents acknowledge a significant effect on the habits of their peers, just 1 percent feel the efforts of pharmaceutical representatives greatly impact their own prescribing habits . Similarly, 61 percent think the drug reps exert no influence on their own practice, while only 16 percent assume that other physicians are not influenced . In addition, the likelihood that residents believe they are influenced by promotional items decreases with the number of items accepted . Even when residents recognize gifts as inappropriate, they often take them anyway . More than half of residents admit they would be unlikely to maintain the same degree of contact with pharmaceutical representatives if not for free lunches and other promotional items .
Residents are not the only physicians potentially swayed by pharmaceutical funding. Physicians in leadership positions, who influence the decisions of other physicians, may themselves be influenced by the pharmaceutical industry. Physicians recommending formulary additions are more likely to have received drug company money to attend or speak at symposia or perform research (odds ratio 5.1, 2.0-13.2) . Over half of authors of clinical practice guidelines have preexisting relationships with companies producing drugs reviewed in the guidelines .
Pharmaceutical representatives often provide meals at which well-known physicians are paid to speak, in the name of education. The objectivity of these speakers is arguably compromised by their honoraria and a sense of loyalty to the industry representatives at the rear of the room. A physician who portrays the featured drug unfavorably will not have a future opportunity to "educate" other providers on behalf of the company. When representatives themselves give the lectures, all inaccurate statements are favorable to the drugs being promoted .
Lunches, pens, and other promotional items all play a role in drug marketing, but pharmaceutical companies spend over half of their promotional budget, 15.9 billion dollars in 2004, on samples . Drug samples, seemingly a gift that would benefit patients, likely serve to make health care more expensive. Patients who finish their samples may fill costly prescriptions for the same products, unaware of inexpensive, generic alternatives. Resident physicians with access to samples are more likely to prescribe advertised medications and less likely to recommend generally cheaper over-the-counter options . Medical institutions including Yale, Stanford, and the University of Pennsylvania have taken steps to limit relations between member healthcare providers and pharmaceutical companies [18, 19]. However, not all institutions have sought to create distance between themselves and pharmaceutical representatives. The Weill Medical College of Cornell University recently opened the Clinique Skin Wellness Center, mostly financed by a $4.75 million grant from Clinique, at which patients may make on-site appointments with Clinique representatives . The ends may justify the means, as one of the stated goals of the clinic is educating patients on skin cancer prevention . However, physicians at that institution may have a difficult time convincing patients and others that the care they deliver is unbiased.
Mounting evidence suggests that physicians are vulnerable to various pharmaceutical marketing strategies. The fact that industry annually spends billions of dollars on advertising geared to physicians implies that such advertising is effective. The most direct way for physicians to avoid a conflict of interest with pharmaceutical companies is to eschew all types of gifts from those companies. Some feel that interactions with pharmaceutical representatives are too useful to abandon. Those providers who continue to interact with drug reps should view all gifts with skepticism, avoid the appearance of impropriety, and exercise caution to prevent compromise of the patient-physician relationship.
