Abstract

The storage and retrieval of medical information is provided by use of a database that facilitates accurate clinical audit, research and/or presentation activities. Comprehensive patient information may be retrieved based on patient descriptive categories including the anatomy, pathology or clinical presentation, treatment and outcome factors of each case. The categories include data options that may be organized in the form of a hierarchical tree that has branching levels of data options with decreasing specificity. Data from the various levels may be compared, as well as data between individual categories. In some embodiments, selected multimedia data may be accessed based on criteria from data options of the patient descriptive categories.

15. The method of claim 9, further including the step of retrieving multimedia data related to the particular patient data by the identifier.

16. The method of claim 9, wherein the selecting of patient data is by pointing to a location on a graphic representation of an anatomy.

17. The method of claim 9, wherein the data sets of the retrieved patient data matches criterion from the selected criterion and criterion from lower levels of the hierarchical tree.
