UpToDate is an evidence-based, physician-authored clinical decision support resource which clinicians trust to make the right point-of-care decisions. More than 6,500 world-renowned physician authors, editors, and peer reviewers use a rigorous editorial process to synthesize the most recent medical information into trusted, evidence-based recommendations that are proven to improve patient care and quality. Over 1.3 million clinicians in 187 countries and nearly 90% of major academic medical centers in the United States rely on UpToDate to provide the best care. More than 80 research studies confirm widespread usage of UpToDate and the association of its use with improved patient care and hospital performance — including reduced length of stay, fewer adverse complications, and lower mortality. UpToDate has earned the trust of the healthcare community over more than 25 years because of the integrity of its recommendations, including the fact that we never accept funding from pharmaceutical companies, medical device manufacturers, or other commercial entities. UpToDate topics are viewed more than 43 million times per month, and our 2016 subscriber survey found that clinicians find the answers to their question over 94% of the time. This success reflects the breadth (25 specialties) and depth of our clinical content (over 11,000 topic reviews, each of which answers multiple clinical questions).
