Conflicts of interest and relations with industry
- Topic
A conflict of interest exists when a personal gain could sway a clinical decision; it is declared, managed and, if serious, avoided.
What it is
A conflict of interest exists when professional judgement about the patient, research or teaching may be swayed by a secondary interest, such as a payment, a gift, an investment or a personal tie. It does not require bad intent: the risk of influence is enough. The World Medical Association asks that every real or potential conflict be declared and that the patient's interest come first. In Colombia, Law 23 of 1981 forbids accepting commercial benefits from those who supply what the doctor prescribes, and Law 1751 of 2015 bans gifts from industry to professionals.
Key facts
- Primary interest: the patient's welfare and the validity of research; secondary interest: financial gain, prestige, relationships.
- Types: financial (payments, fees, shares), non-financial (prestige, career, beliefs) and institutional.
- World Medical Association: real or potential conflicts, financial or personal, must be declared; when they clash, the patient's interest prevails.
- Law 23 of 1981, art. 40: forbids doctors to accept commercial benefits from pharmacies, laboratories, opticians and similar suppliers of what is prescribed.
- Law 23, art. 41: do not accept or give payments for referring patients; arts. 43 and 44: do not charge the institution's patients or steer them to private practice.
- Law 1751 of 2015, art. 17, paragraph: bans any perk or gift, in cash or in kind, from suppliers of medicines, supplies or devices to health professionals and workers.
- Decree 3380 of 1981, art. 25 (Decree 780 of 2016): income from a doctor's lawful ownership ties with those organisations is not a commercial benefit.
In clinical practice
- Prescribing by generic name and according to evidence reduces the influence of commercial promotion.
- When giving a talk or writing a guideline, declare ties with industry before starting.
- Being both treating doctor and researcher for the same patient is a conflict: separate the roles and inform the patient.
- Referring patients to a centre you own without saying so is an undeclared conflict.
Legal framework in Colombia
- Law 23 of 1981, arts. 40, 41, 43 and 44; Decree 3380 of 1981, arts. 25 and 26, compiled in Decree 780 of 2016.
- Statutory Law 1751 of 2015, art. 17, paragraph: ban on gifts from industry; breaches are sanctioned by the ethics tribunals and oversight bodies.
- Law 1164 of 2007, art. 38: duty to report, and not to take part in promoting, products whose harms are known or whose effects are doubtful.
