The Rothman Orthopaedic Institute Foundation

for Opioid Research & Education Board

Message from the President

It is with great pleasure we announce the establishment of the Rothman Orthopaedic Institute Foundation for Opioid Research & Education. As a musculoskeletal specialist, I have witnessed firsthand the lethal effects of unintended opioid addiction, diversion, and abuse; from families shattered by the death of a family member from an opioid-related overdose to communities devastated by widespread opioid-abuse. The latest estimates by the US Department of Health and Human Services finds that approximately 130 Americans die every day from an opioid-related overdose, or over 47,000 deaths annually.


The opioid epidemic is a multi-factorial problem plaguing the United States today. It is a product of a complex interplay between patient dynamics, opioid marketing, demands for aggressive pain management, and unintended dependence on prescription opioids. A multi-factorial problem as significant as the opioid epidemic is going to require a multi-pronged solution.


The Rothman Orthopaedic Institute Opioid Foundation was established in response to this epidemic, and embraces a multi-pronged strategy, which will include:

  • Raising public awareness of the opioid epidemic;

  • Educating patients on safe opioid use;

  • Informing physicians on optimal opioid prescribing strategies;

  • Supporting research aimed to decrease opioid use and potential addiction;

  • Advancing non-opioid pain management strategies; and

  • Advocating for evidenced-based legislative policies.

Our Board and I look forward to pursuing the challenge of curbing the opioid epidemic.
