The John J. Lynch, MD Center for Ethics | MedStar Washington Hospital Center | MedStar Health
In 1982, John “Jack” Lynch, the first medical oncologist in Washington, D.C., founded the hospital’s first Ethics Committee. A few years later, driven by the needs of the hospital, its providers, patients and families, a dedicated Center for Ethics was developed. Today, the John J. Lynch, MD Center for Ethics serves as MedStar Washington Hospital Center’s Department of Bioethics, whose consultative section responds to approximately 400 calls per year. The Center’s academic section produces internationally recognized and accredited bioethics education programming and publishes the Journal of Hospital Ethics, the only peer-reviewed and research-indexed publication from MedStar Health. The Center is additionally involved in both theoretical and clinical research resulting in policy development for the immediate institution, and continuous, leading contributions to the professional field.
