Opioid Stewardship Fellow

Rachel McFadden, BSN, RN, CEN

The foundation of her clinical philosophy and practice is harm reduction – a social justice movement as well as a practical approach to reducing the negative consequences of substance use. In addition to producing concrete evidence-based strategies to improve the health and well-being of people who use drugs, harm reduction shines a light on the rich, everyday opportunities health professionals have to learn from and work with people who use drugs. As a Bloomberg Fellow at the Johns Hopkins School of Public Health, her work centers on reducing stigma, and strengthening Penn’s capacity to respond to the opioid/substance use crisis through the integration of harm reduction, and bridging Penn’s medical services to community-based and public health efforts.
