Doctors, nurses, residents and medical practitioners throughout the healthcare enterprise are always on the move treating patients in offices, satellite locations and hospital wards. They must make decisions based on a large body of constantly changing information regarding diseases, drugs and drug interactions. As information about new diseases, research, drugs and interactions become known on a daily basis, practitioners need to be able to treat patients based not only on what has been learned in school and in daily practice, but also based on the late breaking medical news of the day. Today's practitioners are facing a new world of medicine - a highly mobile environment where they are required to treat patients with constantly changing dynamic information.
