eMedicine is an online clinical medical knowledge base founded in 1996 by Scott Plantz MD FAAEM, and Jonathan Adler MD MS FACEP FAAEM, a computer engineer Jeffrey Berezin MS. The fundamental concept was to create a large repository of professional level medical content that could be both updated and accessed continuously to assist in clinical care and physician education. The eMedicine website consists of approximately 6,800 medical topic review articles, each of which is associated with one of 62 clinical subspecialty "textbooks". Pediatrics, for example, has 1,050 articles organized into 14 subspecialty "textbooks" (Pediatric endocrinology, genetics, cardiology, pulmonology, etc.); the emergency medicine volume has 630 articles and internal medicine has nearly 1,400 articles. If the remainder of the specialty textbooks (e.g., Neurology, Orthopedics, Ophthalmology, etc.) are added to the total 6800+ articles were created in eMedicine. In addition, the knowledge base includes over 25,000 clinically multimedia files (e.g., photographs, imaging studies, audio files, video files). To create this online content over 11,000 board certified healthcare specialists (95%+ physicians, 95%+ US based) were recruited and managed in a first generation, proprietary learning management system (LMS). If printed out in hardcopy form, the system's content would total over 1 million pages.
