McKesson says that more than 75,000 healthcare professionals including physicians, nurses, office and IT administrative staff and others at as many as 500 healthcare organizations within the U.S., but also Canada, France and the Netherlands are using HorizonWP Physician Portal to access patient health records. The company says that usage of the system has doubled from last year and now logins per month exceed 2 million.
   
HorizonWP Physician Portal is an internet gateway that lets community-based physicians, hospitalists and other caregivers log on once to gain single-source access to the patient's virtual electronic health record, no matter where the data resides.  The functionality is similar to that found on popular consumer web portals such as Yahoo, the company said.
