Concordance Between Dermatologist Self-reported and Industry-Reported Interactions at a National Dermatology Conference

Comment

In this study, we demonstrated discordance between dermatologist self-reported financial interactions in the AADMP compared with those reported by industry via OP. After excluding f/b/t/l entries, approximately two-thirds of the total amount and number of payments in OP were disclosed, while 31% of dermatologists had discordant disclosure status.

Prior investigations in other medical fields showed high discrepancy rates between industry-reported and physician-reported relationships ranging from 23% to 62%, with studies utilizing various methodologies.^{6-9,11,12,14,15} Only a few studies have utilized the OP database.^8,12,15 Thompson et al¹² compared OP payment data with physician financial disclosure at an annual gynecology scientific meeting and found although 209 of 335 (62%) physicians had interactions listed in the OP database, only 24 (7%) listed at least 1 company in the meeting financial disclosure section. Of these 24 physicians, only 5 (21%) accurately disclosed financial relationships with all of the companies listed in OP. The investigators found 129 (38.5%) physicians and 33.7% of the $1.99 million OP payments had concordant disclosure status. When they excluded physicians who received less than $100, 53% of individuals had concordant disclosure.¹² Hannon et al⁸ reported on inconsistencies between disclosures in the OP database and the American Academy of Orthopedic Surgeons Annual Meeting and found 259 (23%) of 1113 physicians meeting inclusion criteria had financial interactions listed in the OP database that were not reported in the meeting disclosures. Yee et al¹⁵ also utilized the OP database and compared it with author disclosures in 3 major ophthalmology journals.Of 670 authors, 367 (54.8%) had complete concordance, with 68 (10.1%) more reporting additional overdisclosures, leading to a discordant with underdisclosure rate of 35.1%. Additionally, $1.46 million (44.6%) of the $3.27 million OP payments had concordant disclosure status.¹⁵ Other studies compared individual companies’ online reports of physician payments with physician self-disclosures in annual meeting programs, clinical guidelines, and peer-reviewed publications.^6,7,9,11,14

Our study demonstrated variation in disclosure status. Compared with other groups, dermatologists in the discordant with overdisclosure group on average had more interactions with and received higher payments from industry, which is consistent with studies in the orthopedic surgery literature.^8,9 Male dermatologists had 11% more discordant disclosures than their female counterparts, which may be influenced by men having more industry interactions than women.³ Although small industry payments possessed the lowest concordant rate in our study, which has been observed,¹² payments greater than $100,000 had the second-lowest concordance rate at 58%, which may be skewed by the small sample size. Rates of concordant disclosure differed among types of interactions, such as between research and associated research payments. This particular difference may be attributed to the incorrect listing of dermatologists as principal investigators or reduced awareness of payments, as associated research payments were made to the institution and not the individual.

Reasons for discrepancies between industry-reported and dermatologist-reported disclosures may include reporting time differences, lack of physician awareness of OP, industry reporting inaccuracies, dearth of contextual information associated with individual payment entries, and misunderstandings. Prior research demonstrated that the most common reasons for physician nondisclosure included misunderstanding disclosure requirements, unintentional omission of payment, and a lack of relationship between the industry payment and presentation topic.^9,12 These factors likely contributed to the disclosure inconsistencies in our study. Similarly high rates of inconsistencies across different specialties suggest systemic concerns.

We found a substantial number of dermatologist-industry interactions listed in the AADMP that were not captured by OP, with 108 dermatologists (35%) having overdisclosures even when excluding f/b/t/l entries. The number of companies in these overdisclosures approximated 4 times the number of companies on OP. Other studies have also observed physician-industry interactions not displayed on OP.^8,12,15 Because the Sunshine Act requires reporting only by certain companies, interactions surrounding products such as over-the-counter merchandise, cosmetics, lasers, novel devices, and new medications are generally not included. Further, OP may not capture nonmonetary industry relationships.

There were several limitations to this study. The most notable limitation was the differences in the categorizations of industry relationships by OP and the AADMP. These differences can overemphasize some types of interactions at the expense of other types, such as f/b/t/l. As such, analyses were repeated after excluding f/b/t/l. Another limitation was the inexact overlap of time frames for OP and the AADMP, which may have led to discrepancies. However, we used the best available data and expect the vast majority of interactions to have occurred by the AAD disclosure deadline. It is possible that the presenters may have had a more updated conflict-of-interest disclosure slide at the time of the meeting presentation. The most important limitation was that we were unable to determine whether discrepancies resulted from underreporting by dermatologists or inaccurate reporting by industry. It was unlikely that OP or the AADMP alone completely represented all dermatologist-industry financial relationships.

Conclusion

With a growing emphasis on physician-industry transparency, we identified rates of differences in dermatology consistent with those in other medical fields when comparing the publicly available OP database with disclosures at national conferences. Although the differences in the categorization and requirements for disclosure between the OP database and the AADMP may account for some of the discordance, dermatologists should be aware of potentially negative public perceptions regarding the transparency and prevalence of physician-industry interactions. Dermatologists should continue to disclose conflicts of interest as accurately as possible and review their industry-reported interactions listed in the OP database.
