Piet de GroenThe computer was introduced in healthcare facilities to store and process demographic and financial data. At present, the content of the medical record is being transferred from paper to electronic media, with some facilities being paperless and others still partially paper-based. The physician reads and processes the data as needed during the medical decision-making process. However, the increasing complexity of the medical field and the flood of data expected to be generated by genomic tests will demand that data are preprocessed by computer algorithms before being presented to the physician. Such processing can be based on guidelines — experience of experts converted to computer-based "rules" — or on statistical analysis of the outcome of patients with similar characteristics — "mining" of the data collected in large sets of electronic medical records. At Mayo Clinic Rochester, in collaboration with IBM, we have created a data warehouse that will allow us to store clinical as well as genomic data of millions of patients. In addition, we have created a search engine that can identify subsets of patients with specific features. Expansion of the data within the warehouse and development of new algorithms to analyze and mine across all types of data are the focus of next steps in the collaboration. Eventually, this may lead to computationally-derived, patient-specific recommendations which are available to the physician during the medical decision-making process.

Dr. Piet de Groen is a consultant in Gastroenterology and Hepatology at the Mayo Clinic in Rochester, MN. He is an Associate Professor in Medicine and Gastroenterology at Mayo Medical School. Dr. de Groen's clinical research objective is to decrease the mortality due to cholangiocarcinoma (cancer of the bile ducts) by actively pursuing early detection of this disease in patients at risk, develop new or improve current diagnostic modalities, and finally investigate new treatment options. Mayo Clinic Rochester is one of the largest referral centers for this type of tumor. In addition, Dr. de Groen has an interest in bioinformatics. He has led the development of web-based databases and applications for the Mayo Clinic Cancer Center in Rochester and currently is the Program Director at Mayo Clinic Rochester of the Mayo Clinic/IBM Computational Biology Collaboration which is developing a comprehensive prototype system for access to and interpretation of clinical, genomic as well as proteomic data.
