Abstract

Physician-industry relationships have come a long way since serious debates began after a 1990 Senate Committee on Labor and Human Resources report on the topic. On one side, the Sun Shine Act of 2007, now a part of the Patient Protection and Affordable Care Act that mandates disclosure of payments and gifts to the physicians, has injected more transparency into the relationships, and on the other side, numerous voluntary self-regulation guidelines have been instituted to protect patients. However, despite these commendable efforts, problem persists. Taking the specific case of physician-pharmaceutical sales representative (PSR) interactions, also called as detailing, where the PSRs lobby physicians to prescribe their brand drugs while bringing them gifts on the side, an August 2016 article concluded that gifts as small as $20 are associated with higher prescribing rates. A close examination reveals the intricacies of the relationships. Though PSRs ultimately want to push their drugs, more than gifts, they also bring the ready-made synthesized knowledge about the drugs, something the busy physicians, starving for time to read the literature themselves, find hard to let go. Conscientious physicians are not unaware of the marketing tactics. And yet, physicians too are humans. It is also the nature of their job that requires an innate cognitive dissonance to be functional in medical practice, a trait that sometimes works against them in case of PSR interactions. Besides, PSRs too follow the dictates of the shareholders of their companies. Therefore, if they try to influence physicians using social psychology, it is a job they are asked to do. The complexity of relationships creates conundrums that are hard to tackle. This commentary examines various dimensions of these relationships. In the end, a few suggestions are offered as a way forward.

Introduction

Trust is considered to be a key component or a cornerstone while discussing provider-patient relationship.1-4 Medical ethics is an imperative in the practice of health care for inculcating professionalism and building trust.5 However, providers being humans first, their vulnerability to conflict of interest is well documented in ancient6-8 as well as modern history.9

Drugs make a big part of modern therapeutics. Furthermore, drugs have become expensive and pharmaceutical companies stand to gain a lot if more of their brand drugs are sold. For most part, physicians are the agents who write prescriptions. Therefore, it serves pharmaceutical industry to persuade physicians to prescribe their brand drugs preferentially and in high volumes. One of the ways in which industry accomplishes this objective is via one-on-one marketing in the form of physician-pharmaceutical sales representative (PSR) interactions, also called as detailing. In detailing, PSRs try to convince the physicians how their company products are the best and need to be prescribed, although marketing their brand is not the sole objective or purpose of detailing. It is also meant to provide busy physicians up-to-date information about the pros and cons of using the promoted drugs and to keep them abreast with the cutting-edge advances in the field in general. The borderline between genuine recommendation and profit-oriented persuasion is thin. Using smart marketing strategies and tactics such as offering gifts, friendship, and flattery, PSRs can influence physicians to prescribe their brand drugs in excess. While legitimate prescriptions are necessary and help patients, the profit incentives create an opportunity for misuse and conflict of interest leading to violation of medical ethics on the part of the physicians.

Lately, physician-pharmaceutical industry relationships have come under great scrutiny. While the old reasons for concern such as increased vulnerability to side effects and potential for being subjected to unnecessary ineffective treatment are still valid, what appears to be strongly driving the recent enhanced interest in the topic are the economic factors. In 2012 alone, pharmaceutical industry spent $89.5 billion on detailing, accounting for 60% of the global sales and marketing spending.10 It is known that the brand prescriptions add to the cost of care, mostly at no added value.11 When the increasing health care cost is becoming a global concern,12 it is natural that the stakeholders would scrutinize physician-industry relationships related to excessive prescribing. Another cost-related factor could be an increase in the litigations due to adverse drug events following an increase in the brand or off label prescriptions. For example, between 2009 and 2010, 8 cases involving issues of drug safety were settled for $8.6 billion.13

Following excesses in prescribing in 1980s, a report of the 1990 Senate Committee on Labor and Human Resources set forth the discussions, debates, and actions on this issue.14 However, as Mulinari says, there also appears to be cyclicality in the phenomenon.15 For example, in 2003, Katz et al mentioned that gifts of negligible value can influence the behavior of the recipient.14 Almost 13 years later, the same sentiment is echoed in an August 2016 article.16 In 2016 alone, there is a volley of articles on the topic of industry-sponsored gifts/payments and their impact on the prescribing patterns of the physicians, bringing perspectives from diverse fields such as public health, epidemiology, health policy, regulation, law, and from diverse geographies like Ethiopia and Pakistan.15-24

As a caveat, it is noted here that other health professionals such as doctors of pharmacy, physician assistants, and nurse practitioners also carry prescribing authority. Although 2 publications from 2016, included in the citations, address the issues related to nonphysicians, data about them are currently inadequate. Therefore, for the sake of convenience, the article has used the word physician(s) throughout the narrative as the representative of the health professionals with prescribing authority. Similarly, though the physician-industry relationships are spread over diverse domains of activities ranging from big research projects involving a lot of money to small face-to-face interactions between an individual physician and a PSR, involving small token gifts such as sponsoring of meals, again for the sake of convenience and focus, the latter is treated as the topic of discussion.

Attempts have been made to mitigate this challenge using different approaches. Numerous self-regulatory initiatives such as American Medical Association (1990) guidelines for gifts to physicians from industry, or “Pharmaceutical Research & Manufacturers of America” (2002) guidelines for ethical conduct of sales representatives have been instituted.25 Academic Medical Centers are increasingly restricting PSR access to their physicians.10,26 On the legal front, between 1993 and 2005, several US states adapted laws for transparency and disclosure of industry payments to physicians.27 In addition, the 2007 Sunshine Act that required pharmaceutical and medical device makers to collect, track, and report financial relationships with physicians and teaching hospitals is now a part of the 2010 Patient Protection and Affordable Care Act in the United States.15 Furthermore, US Food and Drug Administration keeps a watch on the conduct of the industry using whistle-blower incentives.28 Europe, Canada, and Australia have been equally engaged in addressing this issue, and in those countries equivalent self-regulatory and legislative regulatory checks and balances are in place.15 In emerging economies like India and China, however, the landscape appears to be murky.29

What stands out in this, about quarter of a century-long story regarding the conflict of interest generated by physician-industry financial relationships and the attempts to mitigate it, is that the problem still persists. Despite efforts to dissuade or restrict physician-PSR encounters that are accompanied by gifts to physicians, data show that these interactions are known. A study based on 2013 Medicare data found that 2% to 12% physicians received payments in the form of sponsored meals related to promotion of the target drugs.16 Two studies in Germany that sampled different groups of physicians in 2010 showed that 77% to 84% of the physicians saw PSRs at least once a week and they accepted gifts.30,31

The physician-industry relationships, even if laden with the conflict of interest, cannot be simply wished away. There are arguments that these interactions add value and are good for the patients.32,33 Moreover, the law itself cannot eliminate physician-industry relationships due to the first amendment issue of freedom of commercial speech.22 In the current scenario, small gifts to physicians are allowed. One may think that reducing the limit on the gift amount still further might work, and there have been proposals for a total ban on the gifts.25,26,34 However, the issue appears to be nuanced. Though very small amounts of gift can sway the prescriber patterns of practice,14,16 it is not clear where the de minimis is or whether a total ban will work at all.14

The question is what more can be done? Is there a definitive doable solution? The best way forward might be to understand the perceptions, attitudes, and environments of the prescribers and the marketing strategies of the PSRs. In addition, the circumstances that create catch-22 situations will need a close examination. It is also important to become aware of the rapidly changing landscape of medical science and technology and that of the drug discovery. Without knowing these, optimum viable solutions might prove elusive. The article will take a high-level overview of these topics and then conclude by offering a few comments on the future directions.

Prescribing Physicians: Perceptions and Attitudes

Studies related to the perception and attitudes of the physicians show that mostly physicians deny that they get influenced by the promotional pitches of the PSRs,32,35,36 although there is evidence that physicians admit that they get influenced.21,31 Paradoxically, many physicians believe that their peers get influenced by the marketing though they themselves are immune to it.30,37 Notwithstanding, studies have shown that many physicians are unable to discern between promotional evidence and scientific evidence.38,39 Social psychology theories have tried to explain this phenomenon.33 Sah and Fugh-Berman have nicely elucidated how physicians easily believe biased information and suffer from cognitive dissonance, self-serving biases, and a sense of entitlement.40

PSRs Use Social Psychology Techniques in Their Marketing Strategies

Behind a PSR trying to influence a physician’s prescribing pattern stands a huge industry that he or she serves and represents. Complex analyses and planning in the backend precede the PSR-physician meetings. These include details such as the expected role practice, physician’s broad background, or time management.10 During the meetings, PSRs usually resorts to adaptive selling behavior and alter and adjust the sales behaviors based on the perceived nature of the situation.41 Principles of reciprocation, commitment, social proof, liking, authority, and scarcity, as delineated in social and psychological sciences, are routinely used by the PSRs to influence the minds of physicians at subconscious level.40,42,43 Fugh-Berman and Ahari in their article conclude that “physicians are susceptible to influence because they are overworked, overwhelmed . . . and feel underappreciated . . . bearing food and gifts, drug reps provide respite and sympathy . . .”37 Katz et al remark that food flattery and friendship are powerful tools of persuasion, more so when they are combined.14 However, providing respite and sympathy is only half of the job. Studies show that PSRs downplay the information about safety and side effects and exaggerate benefits regarding their products.43,44 The 2-pronged strategy brings about the desired effects.

Paradoxes and Dilemmas

Physicians and Cognitive Dissonance

On a closer look, it appears that cognitive dissonance is a necessary, inevitable, and unavoidable part of a physician’s persona. Absence of cognitive dissonance can overwhelm a physician and make the practice of clinical medicine impossible. Probably in recognition of this paradoxical anomaly, courts have consistently applied the “learned intermediary doctrine” and used the “independent physician heuristic” in the trials involving pharmaceutical litigations.45 Therefore, education and awareness can assuage the problem, but a residue of dissonance will always remain.

Pharmaceutical Sales Representatives

It is impossible to totally delegitimize the profit-driven business strategies, tactics, and maneuvering of the pharmaceutical industries unless the government owns the industries. Such a socialistic solution is a far cry, but the argument elucidates the daunting nature of the challenge of regulating the pharmaceutical marketing. If the industry uses social psychology to manipulate physicians, then that is what its shareholders’ dictated job is. Managers are paid to think creatively to increase business.10 It is conceivable that if a zero-dollar limit on the gifts is imposed,26 the industry might start offering goodwill gesture free services instead to the physicians in their daily personal lives. As Katz et al wistfully suggest, industry will find out a way to go around the law.14

Changing Landscape of Pharmaceutical and Health care Field

Discussions about the conflict of interest concerning prescribers do not highlight adequately the dramatic changes in the field of health sciences and technologies. The days of blockbuster drugs are over.46 Specialty drugs and personalized medicine domains are already highly monitored and regulated. One wonders if the current topic might lose relevance in 25 years in the futuristic world of telemedicine and medical robotics.

Future Directions

It seems that it is practically impossible to eliminate altogether the conflict of interest in health care. It is also uncertain if public disclosure of physician-industry relationships data in itself will make a major difference in the outcomes, though morally it is the right thing to do. It is suggested that more attention should be given to understanding those problems of the physicians where PSRs are adding value, albeit in exchange of favors. Probably the mid-career physicians suffer the most. They are in scarcity of ready-made up-to-date current usable information. They are neither fresh from the academy to know it all, nor well settled in practice yet to afford the luxury of time to acquire knowledge on their own. A popular article calls doctors as cheap dates for the industry because they get influenced with even small gifts.47 Reality might be subtler. The castigated gift might be the face of the currently undetected issues that bother physicians. While the other measures might be pursued enthusiastically, the best approach today seems to be, as Grande suggests, having public-funded academic detailing programs to replace industry-driven detailing.25
