Conflicts of interest occur when researchers or their institutions have financial or personal ties with other persons or organizations that influence their work or the way it is presented. Financial relationships, such as an employment or consultancy relationship, or stock ownership, are among the most obvious reasons for a conflict of interest. In addition, intellectual passion, dependence on external funding, academic competition, and the interests that funding bodies may have in scientific research can jeopardize a researcher’s independence. Lack of independence can result in substandard science, damage the reputation of the researcher and the research group or institution, and ultimately even negatively affect patient care.

Because some conflicts of interest (particularly those of a non-financial nature) are intrinsic to research, they can never be completely avoided. That is all the more reason to report conflicts of interest as fully and transparently as possible. That will allow peer reviewers, editors, readers or the general public to judge the credibility and plausibility of researchers’ statements against the background of reported conflicts of interest.

Causes

Conflicts of interest can have numerous causes. Two situations that may lead to conflicts of interest are 'external professional activities' and 'collaboration with commercial parties'. Both are described briefly below along with several other examples, originally provided by the Association of American Medical Colleges.

Procedures for reporting potential conflicts of interest

Amsterdam UMC endorses the VSNU regulation for external professional activities (Sectorale regeling nevenwerkzaamheden); the Code for the prevention of improper influence due to conflicts of interest, drawn up by the Royal Netherlands Academy of Arts and Sciences (KNAW) and other parties in 2012 and updated in 2016; as well as the Valorization guideline Naar een goede waarde (in Dutch), issued by the Netherlands Federation of University Medical Centres. The following procedures to handle potential conflicts of interest have been established:
