Scholars and policymakers have long been concerned that the biomedical science literature — and thus the practice of medicine — is biased by the companies who fund research on their own products. Prior research has shown that industry-funded studies tend to produce results favorable to their company sponsors. One solution is disclosure of industry funding, so that physicians and other consumers of the biomedical literature can weigh scientific findings accordingly.
My prior work with Aaron Kesselheim, Susannah Rose, and others has found that adding such disclosures to biomedical abstracts could make a big difference — physicians understand them and will rely upon them. Nonetheless, most journals bury the disclosures at the end of articles, which are often hidden behind paywalls and not nearly as salient as the methods and findings displayed in the abstract. For the Institutional Corruption Lab of the Edmond J. Safra Center, I worked with a team of hackers to create a browser extension that proves the feasibility of adding those disclosures into PubMed, a Federal government database of the scientific literature.
Thankfully, that browser extension is becoming obsolete, as the National Library of Medicine (part of the NIH) has begun implementing such disclosures themselves, right in PubMed. A search reveals that nearly 80,000 abstracts now have such tags. While a lot in absolute terms, it is a small minority of the 17 million abstracts covered by PubMed. Commentators have suggested that as much as 70% of the funding for clinical trials comes from industry, so we should expect millions of abstracts to have such disclosures.
Thus we are still a long way from comprehensive and effective disclosure. There are two problems. Read More
