On April 28 and 29, the FDA held a public workshop on Wound Healing. It was organized by Dr. Dev Verma in the FDA’s Division of Dermatology and Dentistry at the Center for Drug Evaluation and Research. Dr. Verma has actually practiced in a wound center and the insightful list of topics, speakers and panel discussions reflected his deep understanding of the field and its challenges.

On Day 1 I spoke in the morning about one of my favorite topics, the “Nameless” wounds (and whether we can even GIVE wounds names in a meaningful way). On Day 2, I spoke in the morning on Patient Registries and Real World Evidence, and in the afternoon, with Marcia Nusgart, Executive Director of the Alliance of Wound Care Stakeholders on an Economic Evaluation of the Impact, Cost, and Medicare Policy Implications of Chronic Nonhealing Wounds.

I am also proud and grateful to some of my patients who courageously participated. THANK YOU for helping to represent the patient experience of chronic wounds to the FDA so that they understand what problems we need to solve from the patient’s perspective.

Because it was a public meeting, links to the video recordings are available to the public. Eventually the FDA will generate a document to synthesize what they learned, but in the meantime, everyone has access to this incredible 2 day workshop for free. These links do not expire and do not require a passcode.

Here’s the FDA Wound Healing Workshop AGENDA:
