Epocrates announced the launch of Epocrates SxDx, developed in collaboration with Massachusetts General Hospital's Laboratory of Computer Science and Griffith's 5-Minute Clinical Consult. Epocrates SxDx is a disease diagnosis and treatment reference and symptom assessment tool aiding in decision support to clinicians throughout the diagnosis process. Epocrates SxDx is intended for mobile devices, and allows clinicians to enter an unlimited number of symptoms and findings (such as lab results) generating a list of the plausible diagnoses in the Epocrates disease reference. According to Epocrates, "a key differentiating feature of Epocrates SxDx, is the ability of the application to prompt clinicians to refine their input list based on the prevalence and likelihood of patient symptoms and findings. Potential diagnoses are then seamlessly integrated with more than 1,200 disease topics and 3,300 continually updated drug monographs."

According to Epocrates website:

It is available for one and two year individual subscriptions ($69.99 and $109.99). I could not find any information on site licenses for Epocrates SxDx but they do offer site licenses for Epocrates Rx, I would assume you could contact them for a quote for SxDx.
