Development of a Physician Profiling Data Mart by Connie Chambers [email protected] A Thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Computer Information Technology School of Computer and Information Sciences Regis University Denver, Colorado August 10, 2008 Profiling Data Mart vi Abstract Hospitals and medical centers participate in a physician profiling process. This process is important to ensure that physicians are providing safe care and to comply with regulations. One medical center was struggling with the ongoing generation of physician performance reports that were an important part of the profiling process. A design research project was undertaken to demonstrate that an Access-based data mart could successfully streamline this report generating process. The research also demonstrated the need to eliminate excessive detail and deliver highly summarized reports. In addition, the research provided thorough documentation of the entire data mart development approach. This documentation can serve as a resource for future research and/or for other medical centers that might be struggling to manage the profiling report requirements.
