Abstract: Methods of organizing medical data include hierarchically relating a single type of medical or research event to medical data generated from the single type of medical or research event in a computer database environment. Organizing the data in this way enables a researcher to access medical data collected as part of a medical procedure performed on a large number of patients, but at different times. For example, the medical data may be viewed in a more hierarchical fashion, thereby enabling the researcher to further investigate potential relationships between other factors.

Abstract: Methods, systems and computer program products for synthesizing diagnoses stored in healthcare databases are provided. A diagnosis query associated with a single patient or a group of patients is received. Query results are provided responsive to the diagnosis query. The query results may include diagnoses from multiple sources that are expressed in multiple standards formats.
