Open Osmosis (2015) is an initiative committed to developing and disseminating health education resources with the ultimate aim of making healthcare more accessible. With support from the Robert Wood Johnson Foundation, we have curated thousands of open educational resources (OER), including images, videos, and practice questions within a dozen clinician domains. These include anesthesiology, emergency medicine, neurology, dermatology, radiology, psychiatry, learning analytics, obstretics & gynocology, spine & musculosketal medicine, osteopathic principles, pediatrics, opthalmology, and surgery. These were produced and curated by more than 150 medical students, residents, and clinicians from around the world.
