This document discusses the physician-pharmaceutical industry relationship and provides evidence of the influence of industry interactions and gifts on physician prescribing behaviors. It presents several studies that found:
- Physicians who accepted paid trips or meals from drug companies were more likely to prescribe the company's drugs. Prescribing of promoted drugs increased after sponsored trips.
- Physicians who interacted more with drug company representatives were more likely to request the addition of those companies' drugs to their hospital formularies.
- Physicians were more influenced by commercial drug company sources than scientific sources in their knowledge and perceptions of certain drugs.
2. The CAGE Questionnaire
for Drug Company Dependence
• Have you ever prescribed CelebrexTM
?
• Do you get Annoyed by people who complain about drug
lunches and free gifts?
• Is there a medication loGo on the pen you're using right
now?
• Do you drink your morning Eye-opener out of a LipitorTM
coffee mug?
If you answered yes to 2 or more of the above, you may be
drug company dependent.
3. Levels of Interactions:
• Clinicians
– gifts
– promotional information
• Researchers
• Professional societies; medical journals
• Continuing medical education (CME)
4. Case
It is a busy day in the office, but you have agreed to speak
for a minute to a pharmaceutical representative who has
stopped by to drop off some samples of a new quinolone
antibiotic, called Ubiquinone. Knowing your interest in
golf, he has brought you golf balls emblazoned with the
letter “U,” and also invites you to a round of golf at the
country club this weekend.
Would you accept the golf balls?
Would you accept the invitation?

21. American Medical Association
Council on Ethical & Judicial Affairs
• “Any gifts accepted by physicians individually should
primarily entail a benefit to patients and should not be of
substantial value.”
• “Subsidies from industry should not be accepted directly
or indirectly to pay for the costs of travel, lodging, or
personal expenses of the physicians who are attending the
conferences and meetings . . .”
• “No gifts should be accepted if there are strings attached.”
JAMA 1991;261:501
22. American College of Physicians
Guidelines on Physician-Industry Relations
• The acceptance of individual gifts, hospitality, trips, and subsidies of all
types from industry by an individual physician is strongly discouraged.
• The acceptance of even small gifts can affect clinical judgment and
heighten the perception (as well as the reality) of a conflict of interest..
• The dictates of professionalism require the physician to decline any
industry gift or service that might be perceived to bias their judgment,
regardless of whether a bias actually materializes.
• Ideally, physicians should not accept any promotional gifts or amenities,
whatever their value or utility, if they have the ability to cloud professional
judgment and compromise patient care.
Annals of Internal Medicine 2002;136:396-402.
23. American College of Physicians
Guidelines on Physician-Industry Relations
Acceptable industry gifts:
• Inexpensive gifts for office use (pens and calendars).
• Low cost gifts of an educational or patient-care nature (such as textbooks).
• Modest refreshment.
Annals of Internal Medicine 2002;136:396-402.
24. PhRMA Code on interactions with healthcare
professionals
• Items primarily for the benefit of patients may be
offered to healthcare professionals if they are not of
substantial value ($100 or less).
• Items of minimal value may be offered if they are
primarily associated with a healthcare professional’s
practice.
• Items intended for the personal benefit of healthcare
professionals (CDs, tickets to a sporting event) should
not be offered.

42. “Gifts are just a form of promotion
or advertising, and advertising is a
part of our society, like it or not.”
43. Gifts:
• Cost money (like other advertising).
• Influence behavior (like other advertising).
• Create obligation, need to reciprocate (unlike
advertising). Conflict of interest
• Create sense of entitlement (unlike
advertising).
• Erode professional values; demean
profession (probably unlike advertising).
44. Conflict of interest
Set of conditions in which judgement concerning
a primary interest tends to be unduly influenced
by a secondary interest.
NEJM 1993;329:573-6
45. Conflict of interest?
“I have never been bought, I
cannot be bought. I am an
icon, and I have a reputation
for honesty and integrity,
and let the chips fall where
they may.” “It is true that
there are people in my
situation who could not
receive a million-dollar
grant and stay objective.
But I do.”

68. Pharmaceutical Advertisements in Leading Medical
Journals: Experts’ Assessments
FDA regulations specify that ads are false, lacking in fair
balance, or otherwise misleading if:
• They make claims about relative safety and efficacy or
about the populations in which the drug is useful that
are not supported by the current literature.
• Use literature or references inappropriately to support
claims in the advertisement.
• Use statistics erroneously.
• Use headlines, sub-headlines, or pictorial or other
graphic material in way that is misleading.

Industry often claims that it is an important source of readily available information for the “busy physician.” However, there now exist numerous unbiased (or at least less biased), non-industry-related, readily accessible sources of information where physicians can access evidence-based drug information in minutes, if not seconds. In the age of the World Wide Web certainly there is no need to rely on commercial sources for drug information.
