Abstract

The Open Payments Program (OPP) was recently implemented to publicly disclose industry payments to physicians, with the goal of enabling patient awareness of potential conflicts-of-interests. Awareness of OPP, its data, and its implications for transplantation are critical. We used the first wave of OPP data to describe industry payments made to transplant surgeons. Transplant surgeons (N=297) received a total of $759,654. The median (IQR) payment to a transplant surgeon was $125 ($39–1018), and the highest payment to an individual surgeon was $83,520; 122 surgeons received <$100, and 17 received >$10,000. A higher h-index was associated with 30% higher chance of receiving >$1000 (RR/10 unit h-index increase= 1.181.301.44, p<0.001). The highest payment category was consulting fees, with a total of $314,448 paid in this reported category. Recipients of consulting fees had higher h-indices, median (IQR) of 20 (10–35) vs. 9 (317) (p<0.001). Ten of 122 companies accounted for 62% of all payments. Kidney transplant (KT) and liver transplant (LT) centers that received >$1,000 had higher center volumes (p<0.001). LT centers that received payments of >$1,000 had a higher percentage of private-insurance/self-pay patients (p<0.01). Continued surveillance of industry payments may further elucidate the relationship between industry payments and physician practices.

INTRODUCTION

The Open Payments Program (OPP), also known as the Physician Payment Sunshine Act, was implemented by the Centers for Medicare and Medicaid Services (CMS) to create transparency regarding the financial relationships between physicians and the biomedical industry. Manufacturers of drugs, medical devices and supplies have been mandated to submit their payment records and any “transfers of value” (greater than $10) paid to physicians to the CMS. The data from August 1, 2013 to December 31, 2013 were made available to the general public on September 30, 2014, and moving forward, will be publicized annually (1). The stated rationale is to allow patients to identify potential conflicts-of-interest, and to enable them to make more informed decisions when choosing a health care provider (2). Recognizing the importance of industry support for research, CMS has designated separate databases for disclosing research funding and non-research payments (3). Research funding is a different domain of potential industry influence on physician behavior, and the majority of public concern is in direct payments and gifts to individual physicians (4, 5).

Patients believe that industry relationships influence physician behavior and should be disclosed (5). However, national statistics have never been reported, and reports to date have been disputed by both physicians and industry. In 2007, a national survey documented that 94% of U.S. physicians reported some form of relationship with industry (6). Data from market research companies in 2004, reported that U.S. pharmaceutical companies spent $57.5 billion, or 24.4% of their revenue, on product promotion (7). The OPP represents the first nationwide report of financial relationships that have been confirmed by both industry and physician. The data were reported directly by industry and, prior to the data release, health care providers were given the opportunity to dispute a reported payment.

In solid organ transplantation, the pharmaceutical industry has played a significant role in improving patient outcomes, particularly through the development of novel immunosuppression agents and the subsequent funding of large multicenter randomized trials (812). Given the central role of our field in organ donation, both deceased and live, the success of transplantation dependents almost entirely on public trust, altruism and good will. The financial relationships between industry and our field, other than research payments, both perceived and documented, could substantially affect this public trust. However, the specifics of these financial relationships, while postulated in the media, have never been formally studied at a national level.

To better understand the relationship between industry and transplantation, the goals of this study of the first wave of non-research OPP data were to: 1) characterize the distribution of industry payments to transplant surgeons; 2) examine whether industry payments were associated with a transplant center’s operative volume and insurance case-mix; and 3) evaluate whether industry payments were associated with a transplant surgeon’s academic contribution, quantified by the h-index.

METHODS

Study Population

All physicians who reported themselves as “Transplant Surgeons” to the OPP were included in the study population (N=176). In addition, we included surgeons who self-reported in the following categories and were also members of the American Society of Transplant Surgeons (ASTS), as matched by last name, first name, and zip code when necessary (N=121): Surgery, Urology, Pediatric Urology, and Pediatric Surgery. A total of 297 individuals identified as transplant surgeons in the OPP dataset were included in the study.

Data Sources and Linkages

Payments made to transplant surgeons between August 1, 2013 and December 31, 2013 were obtained from the OPP datasets available on the CMS website (http://www.cms.gov/openpayments) and accessed on September 30, 2014. Physician-level payments were aggregated using the unique physician identification number. In the data published by the OPP, zip codes were identified from each transplant surgeon’s postal address. Using their zip codes, surgeons were linked at a state level. A surgeons’ transplant center affiliation was determined by linking them to the transplant center’s zip code. Transplant center zip codes were ascertained using data from the Scientific Registry of Transplant Recipients (SRTR). Where zip codes were not linkable, they were linked by the institution they reported in ASTS. Non-unique matches were resolved through internet search. 100% of the surgeons were successfully linked by state.

Transplant center operative volume and insurance case mix from January 1, 2012 to December 31, 2013 was obtained from SRTR data. The SRTR data system includes data on all donor, wait-listed candidates, and transplant recipients in the US, submitted by the members of the Organ Procurement and Transplantation Network (OPTN), and has been described elsewhere (13). The Health Resources and Services Administration (HRSA), U.S. Department of Health and Human Services provides oversight to the activities of the OPTN and SRTR contractors. Center level characteristics were explored separately for kidney transplants (KT), liver transplants (LT), as well as the combination of KT and LT. When studying either KT or LT, only data from centers that performed that specific organ transplant were included.

Payments Made to All Health Care Providers and Transplant Surgeons

The OPP data were used to ascertain the total amount of payments made by industry to all Health Care Providers (HCP). HCP consisted of physicians, dentists, podiatrist and nurse practitioners. This was then compared to the total amount of payments made to transplant surgeons.

Distributions of Payments made to Transplant Surgeons

The total amount that each transplant surgeon received was studied and presented as a box and whiskers plot. The amount received was also categorized as follows: less than $100, $100-$999, $1,000-$9,999, and greater than $10,000 and presented as bar graphs. All companies and the amount of payments they made to transplant surgeons were identified (Appendix 1). Payments of the ten highest paying companies and their distribution by categories were shown. Heat maps were used to show the geographic distribution of industry payments collectively by state, as well as the average payments per transplant surgeon in each state.

Payments Categories

OPP payments were reported under the following categories: consulting fees; food and beverage; honoraria; education; travel and lodging; entertainment; gifts; services other than consulting, including serving as faculty or as a speaker at a venue other than a continuing education program (abbreviated as ‘speaker non-CEP’); and serving as faculty or as a speaker for a non-accredited and non-certified, continuing education program (abbreviated as ‘speaker CEP’). The number of transplant surgeons that received payments for each payment category was quantified.

Distribution of Payments by Transplant Center Characteristics

Transplant surgeons were linked to their affiliated transplant centers. 96% of transplant surgeons were successfully linked to 126 transplant centers. The sum of all payments made by industry to individual transplant surgeons at their affiliated center was calculated; these were described as center-payments, but the term center-payment does not mean industry payments made directly to a transplant center. Center-payments were then divided into payment categories of less than $1,000 or $1,000 or more. Based on these center-payment categories, we explored whether center-payments were associated with center volume or insurance case mix. Centers were further differentiated based upon the transplant organ of interest: KT, LT, and collectively for both KT and LT.

Payments Based on Transplant Surgeons’ h-index

To explore if transplant surgeons’ academic productivity was associated with the amount of payments that they received, we ascertained each individual transplant surgeon’s h-index from Scopus as of October 20, 2014. Initially introduced by Hirsh in 2005, the h-index is calculated by determining the number of papers, h, from a researcher with citation counts of h or greater for each paper (14). H-indices were identified for 261 (88%) surgeons. We calculated the total number of payments received by each physician and modeled the relative risk of a physician’s receiving $1,000 or more in total payments using Poisson regression with a robust variance estimator (15). We studied the association between h-index and receipt of payments in each category.

Statistical Analysis

Analyses were performed with R 3.1.1 (the R Foundation for Statistical Computing, Vienna, Austria). For all analyses, p < 0.05 was considered statistically significant. To compare center volumes and insurance case mix, we used the Wilcoxon rank sum test. 95% confidence intervals are reported as per the methods of Louis and Zeger (16).

RESULTS

Payments Made to All Physicians

During this first OPP reporting period, industry made payments totaling $508,215,270 to 359,402 HCPs. Total payments per HCP were: median (IQR) of $95 ($29–258) and a mean of $1,414; the top 5 received $7,356,000, $3,994,022, $3,921,410, $3,849,711 and $2,413,281 during the 5 month OPP study period.

Payments to Transplant Surgeons

Transplant surgeons received a total of $759,654, or 0.15% of total payments made to all providers. Individual transplant surgeons received payments from one (59%), two (19%), three (11%), or greater than three (15%) companies. The largest number of companies from which a single transplant surgeon received payments was 17. Total payments per transplant surgeon had a median (IQR) of $125 ($39–1,018) and a mean of $2,558; the 5 highest transplant surgeons received $83,520, $38,484, $34,744, $32,100, and $29,603 (Figure 1A). Of transplant surgeons who received industry payments, 41% received payments below $100, 33% received payments between $100 and $999, 20% received payments between $1,000 and $9,999, and 6% received payments in excess of $10,000 (Figure 1B).

The median (IQR) for each payment and the percentage of transplant surgeons paid by expense category were: consulting fees $2,000 ($1,500-$3,563) to 12% (N=36); travel and lodging $222 ($79-$470) to 23% (N=24); speaker non-CEP $562 ($36-$2075) to 9% (N=27); food and beverage $24 ($13-$88) to 90% (N=269); speaker CEP $2,500 ($1,500-$2500) to 4% (N=11); honoraria $2,000 ($2,000-$2,400) to 2% (N=7); education $85 ($24-$750) to 13% (N=40); entertainment $68 ($39-$103) to 0.1% (N=3); and gifts $28 ($23-$28) to 0.1% (N=3, Table 1).

Distributions of Payments made by Companies

The average total payment made by a single company was $6227 (ranging from $3.47-$96,864). Of 122 companies that made payments to transplant surgeons (Appendix 1), the 10 highest paying companies accounted for $465,585 (62%) of the total payments. The distribution of payments by category from these 10 companies is shown in Figure 2.

These are the 10 companies that were identified to have the highest total amount payments made to transplant surgeons.

Geographic Distribution

In terms of total payments to transplant surgeons in a given state, the highest 5 states were California ($213,122), Texas ($76,033), New York ($75,150), Ohio ($49,427), and Missouri ($42,685), and the 5 lowest states (Delaware, West Virginia, Kansas, Rhode Island, and Colorado) had total payments ranging from $13 to $151. In terms of average payment-per-surgeon, the highest 5 states were Nebraska ($9,555/surgeon), California ($7,349/surgeon), Missouri ($6,098/surgeon), Indiana ($5,221/surgeon), and DC ($5,008/surgeon) and the lowest 5 states (Delaware, West Virginia, Kansas, Colorado, and North Carolina) had per-surgeon average payments ranging from $13–107 (Figures 3A and 3B).

Payments by Affiliated Transplant Center

In terms of the sum of payments to surgeons at a given transplant center, the 6 highest paid transplant centers accounted for a total $375,078 (49%) of the total payments, with amounts of $189,313, $45,861, $38,268, $35,838, $33,550, and $32,248. Surgeons at the remaining centers (N=121) received payments with a median of $614 per center (IQR $94 - $2259). The 5 transplant centers with the lowest industry payments ranged from $11 to $14.

In terms of average payment-per-surgeon, the highest 5 centers had $27,045/surgeon, $19,134/surgeon, $16,593/surgeon, $16,124/surgeon, and $13,624/surgeon, and the lowest 5 centers had per-surgeon average payments ranging from $11 to $14.

Payments by Transplant Center Volume

For all transplants centers (combining KT and LT) the median (IQR) transplant volume was 34 (14–64) at centers that received no center-payments, 66 (35–138) at centers that received center-payments totaling less than $1000, and 130 (61–279) at centers that received center-payments of $1,000 or more. The difference in volume between centers receiving payments of less than $1,000 versus centers receiving no payments was statistically significant (p<0.001), as was the difference between centers receiving payments of $1,000 or more versus centers receiving no payments (p<0.001). The median (IQR) KT volume was 29 (11–57) at centers that received no center-payments, 64 (35–106) at centers that received center-payments totaling less than $1000, and 74 (50–173) at centers that received center-payments of $1,000 or more. The difference in KT volumes between centers receiving payments of less than $1,000 versus centers receiving no payments was statistically significant (p<0.001), as was the difference between centers receiving payments of $1,000 or more versus centers receiving no payments (p<0.001). The median (IQR) LT volume was 23 (10–48) at centers that received no center-payments, 29 (10–63) at centers which received center-payments totaling less than $1000, and 59 (30–96) at centers which received center-payments of $1,000 or more. The difference in volume between LT centers receiving payments of less than $1,000 versus centers receiving no payments was not statistically significant (p=0.07); however, the difference between centers receiving payments of $1,000 or more versus centers receiving no payments was statistically significant (p<0.001, Table 2).

Payments by Insurance Case mix

For all transplants centers (combining KT and LT) the median (IQR) percentage of private insurance/self-pay transplant recipients was 36% (24%−43%) at centers which received no center-payments, 35% (25%−45%) at centers which received center-payments totaling less than $1000, and 43% (39%−49%) at centers which received center-payments of $1,000 or more. The difference in the percentage of private insurance/self-pay patients between centers receiving payments of less than $1,000 versus centers receiving no payments was not statistically significant (p=0.52), however, the difference between centers receiving payments of $1,000 or more versus centers receiving no payments was statistically significant (p<0.001). For KT, the median (IQR) percentage of private insurance/self-pay recipients was 33% (25%−42%) at centers that received no center-payments, 31% (22%−38%) at centers which received center-payments totaling less than $1000, and 38% (27%−43%) at centers which received center-payments of $1,000 or more. The difference in the percentage private insurance/self-pay recipients at KT centers between centers receiving payments of less than $1,000 versus centers receiving no payments was statistically significant (p=0.34), as was the difference between centers receiving payments of $1,000 or more versus centers receiving no payments (p=0.22). For LT, the median (IQR) percentage of private insurance/self-pay was 46% (39%−57%) at centers which received no center-payments, 53% (44%−60%) at centers which received center-payments totaling less than $1000, and 56% (48%−64%) at centers which received center-payments of $1000 or more. The difference in the percentage of private insurance/self-pay patients at LT centers between centers receiving payments of less than $1,000 vs. centers receiving no payments was not statistically significant (p=0.13); however, the difference between centers receiving payments of $1,000 or more vs. centers receiving no payments was statistically significant (p=0.01, Table 2).

Non-Research Payments by H-index

The Median (IQR) of h-indices among the 261 transplant surgeons was 10 (320). Those paid for consulting had a median (IQR) H-index of 20 (10–35) while those not paid for consulting, but who received payments for under other categories had an h-index of 9 (3–17, p<0.001); similar differences were seen only for the categories of travel and lodging (15 [7–33] versus 9 [3–17], p<0.001) and speaking CEP (25 [11–36] versus 9 [3–18], p=0.02, Table 1). Of the 261 transplant surgeons, 69 (26.4%) received total payments of $1,000 or more. Median (IQR) h-index for transplant surgeons receiving $1,000 or more was 15 (6–32), compared to 9 (316) for transplant surgeons receiving less than $1,000. An increase of ten units of h-index was associated with 30% higher chance of a physician’s receiving at least $1000 in total payments (RR=1.18 1.301.44, p<0.001, Figure 4). In other words, a transplant surgeon with an h-index of 17 had a 30% higher chance of receiving at least $1,000 compared to a transplant surgeon with an h-index of 7.

DISCUSSION

Before the implementation of the Sunshine Act, there was much debate and speculation about the potential implications and patient perceptions of the forthcoming OPP data (1, 2, 17, 18). In this national study, we used the newly available OPP data to describe how industry paid $759,654 directly to 297 transplant surgeons. Of all surgeons, 41% received less than $100, and 6% received $10,000 or more. The highest payment to an individual surgeon was $83,520. The median payment of $125 to a transplant surgeon was within the range compared to other medical specialties in the OPP: $102 to dermatologists; $88 to neurosurgeons; and $173 to urologists (18). Centers at which transplant surgeons received $1,000 or more had higher transplant volumes (median 130 versus median 34, p<0.001). An increase of ten units of h-index was associated with 30% higher chance of a transplant surgeons receiving at least $1000 in total payments (RR=1.18 1.301.44, p<0.001).

Collaboration between physician scientists and the pharmaceutical industry has significantly improved immunosuppressive therapies and improved outcomes in transplant recipients (812). To quantify a transplant surgeon’s scientific contributions, we used their h-index. The h-index has been well accepted and used by other specialties to study academic productivity. A greater H-index has been associated with a higher academic rank among US academic programs in various surgical specialties (14, 19). The analysis of transplant surgeons showed that greater academic productivity was associated with higher industry payments, suggesting that the pharmaceutical industry tends to seek scientific leaders in the field for consulting and speaking. One would hope that the research findings of scientific leaders in the field would not be biased by pharmaceutical support, but one is also reminded of the importance of the current practice of reporting potential conflicts of interest in scientific manuscripts and presentations.

The highest payment category was consulting fees, with a total of $314,448 (41%) of all payments paid to 36 (12%) transplant surgeons. Transplant surgeons who received consulting payments tended to have a higher h-index than surgeons who did not receive them. Drug companies may seek out physician-researchers with a higher h-index because their greater knowledge and experience is more likely to lead to advances in therapy. On the other hand, companies may select these researchers as a marketing effort, to gain prestige by associating themselves with opinion leaders in medicine (18). However, it is important to note that our study was not intended to address motivations behind industry payments, but rather to report payment patterns and associations.

Several limitations of our study merit consideration. First, the CMS has designated a different database for disclosures of research funding. In the research database, recipients of payments are both hospitals as well as individuals, thus the payments made to a particular medical specialty for research cannot be comprehensively studied (3). Second, the OPP data withhold identifying payments that were disputed by either physicians or industry, so some of the details might change as the dispute process evolves. Third, since the OPP is intended merely to report the financial data, we cannot make inferences about whether the financial impact affects behavior or is beneficial or harmful to patient care and the field of surgical transplantation. Fourth, the industry is responsible for reporting the data. There is a possibility that payments are reported or categorized incorrectly, and therefore physicians are given an opportunity to review the data before its release. However, inaccurate reporting is considered a crime and the CMS has the right to review accounts of either party. Fifth, there is a possibility that institutions may limit the payment amount made to an individual, in such cases the remaining amount goes to the institution or department. Finally, although the OPP database and ASTS membership were combined to identify transplant surgeons, it is possible that some transplant surgeons did not report themselves as such to OPP and were not ASTS members, excluding them from this study.

In transplantation, physicians and industry have clearly worked together to substantially improve immunosuppression, ultimately leading to better patient outcomes (812). Although intended to provide greater transparency to patients, the payment data by itself are open to speculation (1, 2, 17). In a survey of 2,086 patients, most were unaware of how their physicians are paid (4). Regarding the OPP, Santhakumar states, “with reputations at stake, more detailed explanation is called for if misperceptions are to be minimized” (20). The transplant community needs a better understanding of the OPP data to prevent potential misinterpretation and misunderstanding. In this first national study of transplant surgeons, we found that payments were mostly made for consulting and were associated with academic productivity. Moving forward, it will be interesting to see how the OPP data will impact our field and the public perception of our field.
