ClinicalKey is a medical search engine and database tool owned by medical and scientific publishing company Elsevier that offers access to the medical information it publishes.



ClinicalKey was developed by Elsevier's Global Clinical Reference team and involved consulting more than 2,000 doctors across the world over two years. The service aims to provide a source of clinical answers. It uses the semantic technology of the health information service Healthline Networks. [1] [ dead link ]; employing user behaviour and database terminology to improve search results, rather than simply pattern matching search. [2] [ dead link ] The website was launched in mid-April 2012 in its third iteration after alpha and beta testing versions. It is targeted at health institutions, universities and schools, with individual physician subscriptions launching in the third quarter of 2012. [3] Two applications for mobile phones are due to launch in the second half of 2012. [4]

ClinicalKey marks a change in Elsevier's approach to providing clinical information through aggregated content services rather than the traditional model of journals and textbooks. The service is being marketed as a 'clinical insight engine'. [3]


ClinicalKey gives full-text access to over 600 of Elsevier's journals, 1,000 books, and 9,000 medical and procedural videos. The search engine is aided by taxonomy tags known as "smart content" that uses EMMeT (Elsevier Merged Medical Taxonomy), and a selection of filtering tools including by journal or textbook, clinical guidelines or clinical trials, First Consult reviews, images, or the US National Institute of Health's MEDLINE database (of journal citations and abstracts for biomedical literature). [5] Users can also export citations, images and copyright information into PowerPoint presentations. [4]

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" ; the emergency medicine volume has 630 articles and internal medicine has nearly 1,400 articles. If the remainder of the specialty textbooks are added to the total 6800+ articles were created in eMedicine. In addition, the knowledge base includes over 25,000 clinically multimedia files. To create this online content over 11,000 board certified healthcare specialists 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.
