    The updated ICMJE conflict of interest reporting form

    The great variability in the processes that different journals use to ask about and report authors’ potential conflicts of interest creates confusion for authors, readers, and the public. To help reduce this confusion, the International Committee of Medical Journal Editors (ICMJE) developed an electronic uniform disclosure form and placed it in the public domain in October 2009. The ICMJE member journals piloted the form, encouraged other journals to use it, and invited feedback. We recognised that the reporting of competing interests is complex and nuanced, and sometimes contentious, and thus anticipated modifying the form on the basis of the feedback received. We are grateful to the many authors, editors, and other interested parties who took the time to comment on the form and its implementation. The matters raised ranged from technical problems about the correct deployment of the form (it requires the user to download the free Adobe 8.0 reader or higher to function) to concerns about the ethics of inquiring about non-financial associations. The committee considered these valuable comments and revised the form at its most recent meeting.

    We made several modifications. The major change in the reporting instrument is the removal of the queries about potential competing interests of authors’ spouses and minor children and about non-financial competing interests. The change was based on the largely negative feedback that we received about these sections. People who commented about this problem made it clear that it is immensely difficult to define competing interests beyond those that involve the direct exchange of money from an interested party to an individual author or the author’s institution. Because the committee continues to believe that there are situations in which indirect or non-financial factors could influence (or seem to influence) the conduct or interpretation of work, we replaced the specific questions with a single open ended query (new section 4) that asks, “Are there any other relationships or activities that readers could perceive to influence, or that give the appearance of potentially influencing, what you wrote in the submitted work?” This change places the onus on the person completing the form to identify and report appropriate non-financial competing interests. It has the advantage of being less intrusive than the previous queries, while providing a locus where authors can report non-financial relationships that may be perceived as potential conflicts of interest.

    In response to comments about the clarity of the form, each field in the form now has a numerical designation. We have modified the language in the instructions and in the individual queries. To make the form more useful to non-native English speakers, we are creating a glossary of terms used in the form and will be posting guidelines for translation of the form’s instructions into multiple languages. The translation of this form is particularly challenging because translations must capture the essence of the queries rather than their literal meaning. The glossary and instructions will be available at in the next few months; translations will be posted on the ICMJE website as they become available.

    The new form, in English, is currently available on the ICMJE website and the websites of our member journals. Authors who have completed the older version of the form in conjunction with a journal submission need not complete the new form, but the new form will be the standard for new submissions. We welcome continued input from the user community. Comments can be sent via the “contact us” link at The committee will consider comments received before 1 May 2011, when we will prepare the next iteration of the uniform conflict of interest disclosure form.

    The complexity, subjectivity, and emotionality of conflict disclosure means that some people will consider this vehicle for reporting to be excessively burdensome while others will think it falls short in one area or another. We cannot, however, let the perfect be the enemy of the good. We hope that the revised ICMJE form will be another step towards simplifying and standardising reporting of conflicts of interest. A more uniform reporting process will alleviate the confusion that prevails when multiple journals use different reporting formats and ease the reporting burden on the members of the biomedical research community so they can pursue the research that will improve the care that we deliver to our patients. With these thoughts in mind, we encourage all journals to adopt the new version of the uniform disclosure form.
