WMA Statement concerning the Relationship between Physicians and Commercial Enterprises

Adopted by the 55th WMA General Assembly, Tokyo, Japan, October 2004,
amended by the 60th WMA General Assembly, New Delhi, India, October 2009
and by the 71st WMA General Assembly (online), Cordoba, Spain, October 2020


In the treatment of their patients, physicians use medicines, instruments, diagnostic tools, equipment and materials developed and produced by commercial enterprises. Industry possesses resources to finance expensive research and development programmes, for which the knowledge and experience of physicians are essential. Moreover, industry support enables the progress of medical research, scientific conferences and continuing medical education that can be of benefit to patients and the entire health care system. The combination of financial resources and product knowledge contributed by industry and the medical knowledge possessed by physicians enables the development of new diagnostic procedures, drugs, therapies, and treatments and can lead to great advances in medicine.

However, conflicts of interest between commercial enterprises and physicians occur and can affect the care of patients as well as the reputation of the medical profession. The duty of the physician is to objectively evaluate what is best for the patient and to promote the patient-physician relationship, while commercial enterprises are expected to bring profit to owners by selling their own products and competing for customers. Commercial considerations can affect the physician’s objectivity, especially if the physician is in any way dependent on the enterprise.

Rather than forbidding any relationships between physicians and industry, it is preferable to establish guidelines for such relationships. These guidelines must incorporate the key principles of disclosure, transparency, avoidance of conflicts of interest and promoting the physician’s ability to act in the best interests of patients.

The guidelines regulating the Physician-Commercial Enterprise relationship should be understood in the light of WMA core ethical values, as stated in particular in the Declaration of Geneva, the International Code of Medical Ethics. the Statement on Conflict of Interest, and the Declaration of Seoul on Professional Autonomy and Clinical Independence.

The autonomy and clinical independence of physicians should be foremost in all physician decisions for patients, regardless of practice setting, whether government-sponsored, private, for profit or not for profit, investor funded, insurance company employers or otherwise.

Curricula of medical schools and residency programs should include educational courses on the relation between enterprises and the medical profession in the light of ethical principles and values of the profession.
