Updating the Master Patient Index
Charleston Area Medical Center (CAMC) needed a way to update the hospital's master patient index with information from ambulatory medical locations. The challenge was getting the hospital's Siemens Invision® system and its Enterprise Access Directory to interface effectively with Medical Manager, which the ambulatory offices are using. Moving patient registration data between these two systems would allow emergency department doctors to determine if patients being treated at the hospital had recently been seen at one of the clinics - particularly important when dealing with those in fragile categories, such as cancer patients.
Boston WorkStation retrieves ADT information from Medical Manager by processing an HL7 file from Medical Manager. The information is then posted into Invision using decision rules that CAMC developed. CAMC not only has the IBM mainframe platform, but also a large numbers of servers running both Windows and Unix. Their Medical Manager data set is a large MSO serialization running on an AIX platform, and Invision runs on a mainframe system.
As a side benefit CAMC was able to develop three daily output reports which list every patient registration the system was able to process and update the information to the master grid. These reports also "red flag" registration errors. The system sends an email to management personnel notifying them of the error and enables data entry staff to review and correct errors, resulting in more accurate patient data.
