[영문]As Massachusetts General Hospital (MGH) was forging ahead with the completion of their new Yawkey Center for Outpatient Care, administrative groups began to struggle with the how they would be able to function in the new building. They would be moving from smaller, isolated practice areas into much larger state of the art facilities with shared common spaces. The affected practices were challenged with developing new workflows and communication processes. After an unsuccessful vendor search, teams from Partners/MGH Information Systems built a solution in-house, using the vendor search requirements as their functional specifications. The application and the new building have been qqqquot;liveqqqquot; since October 2004, and the results have been fantastic. The application is now managing 9,000 patients/appointments a day from all of the appointment scheduling systems used throughout the building.
