Health care professionals need to stay up to date on the latest medical research and topic reviews to provide optimal care. Unfortunately, the process of content discovery is broken with research artificially compartmentalized by publishers and hidden behind countless institutional pay walls. At QxMD, we believe that knowledge translation– the process by which new knowledge is incorporated into clinical practice – is an important and unsolved challenge for our health care system. We hope that ‘Read by QxMD’ will be a part of the solution. Seamless 1-tap access available at thousands of institutions.
