Updating the MPI
Charleston Area Medical Center (CAMC) needed a way to update the hospital's master patient index with information from ambulatory medical locations. 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. This is particularly important when dealing with those in fragile categories, such as cancer patients.
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. A manager in the IT department, realized that integrating information between Siemens Invision and Medical Manager would be time consuming and require manual data entry. This process could result in multiple errors, such as duplicate patient information or, even worse, overwriting good data with incorrect data.
The manager decided to use Boston WorkStation to automate taking selected fields from Medical Manager and expanding them into Siemens Invision in order to get patient information into the main patient database at the hospital.
Boston WorkStation retrieves ADT information from Medical Manager by processing an HL7 file. 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.
