<unk>  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<unk>  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<unk>  volume has 630 articles and internal<unk>  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<unk> . 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. Each article is authored by board certified specialists in the subspecialty to which the article belongs and undergoes three levels of physician peer-review, plus review by a Doctor of Pharmacy. The article's authors are identified with their current faculty appointments. Each article is updated yearly, or more frequently as changes in practice occur, and the date is published on the article.<unk> .com was sold to WebMD in January, 2006 and is available as the Medscape Reference.
