Karen L. Hackett, FACHE, CAE Chief Executive Officer American Academy of Orthopaedic Surgeons 6300 North River Road Rosemont, IL 60018 Dear Ms. Hackett:

In December 2009, I asked for an accounting of industry funding that American Academy of Orthopaedic Surgeons (AAOS) receives from pharmaceutical and medical device companies as well as foundations established by these companies or the insurance industry. I appreciate your response, which I have attached to this letter. I write today to follow up on any efforts by your organization to improve transparency and accountability in its relationships with the pharmaceutical and device industries.

As I stated in my previous letter, I started my inquiry, in part, as a result of accounts documenting the lack of transparency in financial relationships between the pharmaceutical industry and nonprofit health and medical organizations. Specifically, I cited the April 2008 article in The Wall Street Journal, which reported that industry representatives, including ten major drug companies, had formed a coalition to promote looser restrictions on off-label marketing.1 The coalition had asked the National Alliance on Mental Illness (NAMI) to speak in favor of this issue.

In response to my concerns in my April 2009 letter to NAMI, NAMI began to voluntarily disclose to the public any amount of funding exceeding $5,000 that it received from pharmaceutical companies and foundations on its website. Further, NAMI began to provide a brief description of the purpose of the funding on its website. I commend NAMI for its leadership and had hoped that when I reached out to your organization and 32 others, your organization would follow NAMI’s example and begin posting similar funding information on AAOS’s website.

As of the date of this letter, it appears that your organization has taken steps to identify on

its website the corporate or industry sponsors and their range of funding support. However, the

1 Alicia Mundy, “Off-Label Use of Drugs Gets a Push --- Big Pharma Lobbies Washington to Relax Rules on

Marketing,” The Wall Street Journal, April 18, 2008.

website does not specify the purposes of that funding. If AAOS is currently taking steps to further enhance the transparency of its financial relationships with the pharmaceutical and device industries, I would appreciate information regarding those steps. In particular, please state whether or not AAOS will be adding information in the future about the purpose of the funding it receives. If not, please explain why not.

The Medicare Payment Advisory Commission (MedPAC) recommended in a report to

Congress in March 2009 that Congress require that pharmaceutical and device companies report their financial relationships with physician groups, patient organizations, and others. More specifically MedPAC said the following:

Given the potential benefits of public reporting, we recommend that the Congress mandate the reporting of comprehensive information on industry relationships with physicians and other health care entities and that the Secretary post this information on a public searchable website.2

MedPAC then went on to say in Recommendation 5-1 that:

The Congress should require all manufacturers and distributors of drugs, biologicals, medical devices, and medical supplies (and their subsidiaries) to report to the Secretary their financial relationship with:…physician groups and other prescribers…patient organizations; and professional organizations.3

I look forward to working with you and other health and medical organizations to further increase sunshine on financial relationships.

Thank you for your cooperation and attention in this matter. I would appreciate a

response by May 25, 2011. If you have any questions, please do not hesitate to contact Brian Downey for the Committee on the Judiciary at (202) 224-5225.

Sincerely,

Charles E. Grassley
