Abstract: A BUSINESS METHOD in Health Care Management. This relates to a Global Data Center (GDC) for quality assessment and improvement in a medical imaging department by a quality assessment and improvement system (QAISys). Other healthcare areas may similarly benefit from this method. The method provides a unique way to combine computer assisted data exchange between healthcare facilities in the areas of administering, managing, and operating its Quality improvement activities. It provides feedback, instruction, and improvement ideas to enhance the skills of the personnel. National quality benchmarks for procedures and tests are established and monitored. This method is specific to the facility yet draws global national benchmarks from the database. Imaging technologists are the preferred use for this method. This provides a way to combine various existing healthcare systems with simple, new global analysis to accomplish concrete, useful and tangible improvements for the specific healthcare groups.
