Obviously a pharmaceutical company wants to report that its drug is better than a competitor's drug, or better than no treatment; however, due to the threat of litigation, it is not in their interests to suppress or minimise evidence of harm. For the scientists who are conducting the trials, however, the perspective might be different: if it becomes clear that a drug is useless or harmful, then the company will cease to work on the drug and a scientists livelihood could be threatened. Consequently, the responsibility for the integrity of the design and analysis of studies lies squarely with the authors. If the scientists involved in any trial are lacking in competence or integrity, then this will prejudice the value of a trial both for the public and indeed for their industrial sponsors. | Obviously a pharmaceutical company wants to report that its drug is better than a competitor's drug, or better than no treatment; however, due to the threat of litigation, it is not in their interests to suppress or minimise evidence of harm.

Conflicts of interest in health care
Conflicts of interests in individual health care providers
A health care, a conflict of interest is a "situation in which an individual might benefit personally from official or professional actions. It includes a conflict between a person's private interests and official responsibilities in a position of trust. The term is not restricted to government officials. The concept refers both to actual conflict of interest and the appearance or perception of conflict."[1]
"A physician shall, while caring for a patient, regard responsibility to the patient as paramount." Article VIII of the AMA Principles of medical ethics
Physicians should not allow a conflict of interest to influence medical judgment. In some cases, conflicts are hard to avoid, and doctors have a responsibility to avoid entering such situations.
For example, doctors who receive income from referring patients for medical tests have been shown to refer more patients for medical tests [2]. This practice is proscribed by the American College of Physicians Ethics Manual [3].
Vendor relationships
In the USA, a survey reported that 28% of practicing physicians reported receiving money from industry for consulting, giving lectures, or enrolling patients in trials [4] with amounts arranging from $100-$20,000.[5] Studies show that doctors can be influenced by drug company inducements, including gifts and food.[6] Industry-sponsored Continuing Medical Education (CME) programs influence prescribing patterns. [7] Many patients surveyed in one study agreed that physician gifts from drug companies influence prescribing practices. [8] A growing movement among physicians is attempting to diminish the influence of pharmaceutical industry marketing upon medical practice, as evidenced by Stanford University's ban on drug company-sponsored lunches and gifts. Other academic institutions that have banned pharmaceutical industry-sponsored gifts and food include the University of Pennsylvania, and Yale University. [9]
Various groups have made relevant statements:
- Pharmaceutical Research and Manufacturers of America (PhRMA)[10]
- American Medical Association states "Any gifts accepted by physicians individually should primarily entail a benefit to patients and should not be of substantial value."[11]
- American College of Physicians states "The acceptance of individual gifts, hospitality, trips, and subsidies of all types from industry by an individual physician is strongly discouraged."[12]
- Office of the Inspector General of Health and Human Services[13]
The most rigorous statement is by the American Association of Medical Colleges (AAMC):
- American Association of Medical Colleges states "Academic medical centers should establish and implement policies that
prohibit the acceptance of any gifts from industry by physicians and other faculty, staff, students, and trainees of academic medical centers, whether on-site or off-site."[14]
Treatment of family members
Many doctors treat their family members. Doctors who do so must be vigilant not to create conflicts of interest or treat inappropriately.[15][16].
Sexual relationships
Sexual relationships between doctors and patients can create ethical conflicts, since sexual consent may conflict with the fiduciary responsibility of the physician. Doctors who enter into sexual relationships with patients face the threats of deregistration and prosecution. It is estimated that between 2% and 9% of doctors have violated this rule based on a study in the early 1990s [17].
Conflict of interest in research
Financial conflicts
Financial relationships with pharmaceutical manufacturers are associated with authors' published positions.[18] Faculty members[19][20] and institutions[21] with entrepreneurial relationships are associated with data withholding from colleagues or publication (publication bias).
In any publication, there is always some issue with regard to conflict of interest. All the work by scientists is funded by groups such as charities, public bodies or private industry. Accordingly there could be pressure to overstate any outcomes or bias a trial to favor a particular outcome. Unfortunately, the presence of authors with a conflict of interest is not reliably indicated in journal articles.[22] Worse it has been reported that some published articles use 'ghost writers'.[23] Ghost writers may have a conflict of interest but this is not apparent since they are not credited as an author in the byline. Finally, academic scientists gain their professional reputations by publishing in quality journals and purely factual summaries do not necessarily impress journal editors any more than they inspire casual readers.
In the design of randomized controlled trials, industry-sponsored studies may be more likely to select an inappropriate comparator group that would favor finding benefit in the experimental group. This may manifest itself by comparing the effectiveness of a new drug with the effectiveness of an established older treatment rather than choosing a competitors current treatment for comparison.[24] When reporting data from randomized controlled trials, industry-sponsored studies may be more likely to omit intention-to-treat analyses.[25] Regarding the conclusions reached in randomized controlled trials, industry sponsored studies may be more likely to conclude that drugs are safe, even when they have increased adverse effects.[26] Alternatively, the usefulness of drugs may be overstated, although, this is contentious since one study did not find evidence of overstatement.[27] in contrast, a later study found that industry sponsored studies are more likely to recommend the experimental drug as treatment of choice even after adjusting for the treatment effect.[28]
Obviously a pharmaceutical company wants to report that its drug is better than a competitor's drug, or better than no treatment; however, due to the threat of litigation, it is not in their interests to suppress or minimise evidence of harm. For the scientists who are conducting the trials, however, the perspective might be different: if it becomes clear that a drug is useless or harmful, then the company will cease to work on the drug and a scientists livelihood could be threatened. Consequently, the responsibility for the integrity of the design and analysis of studies lies squarely with the authors. If the scientists involved in any trial are lacking in competence or integrity, then this will prejudice the value of a trial both for the public and indeed for their industrial sponsors.
Non-financial conflicts
Non-financial conflicts of interest have been described in medical research.[29]
Conflicts of interests in health care institutions
Vendor relationships
The American Psychiatric Association is reported to have 30% of its financing through the pharmaceutical industry.[30]
