Interactive visual analysis of clinical episodes

An article of manufacture comprising a computer readable storage medium having computer readable instructions tangibly embodied thereon which, when implemented, cause a computer to carry out a plurality of method steps comprising:

• obtaining an episode definition comprising a sequence of timestamped events for an entity that satisfy one or more constraints, wherein said episode definition comprises at least a starting milestone event, an ending milestone event and an outcome measure;
• translating said episode definition to a formal query;
• obtaining matching data that satisfies said formal query from a data repository for a plurality of entities, wherein for each of said entities, said matching data comprises a plurality of timestamped events comprising at least said starting milestone event and said ending milestone event;
• performing temporal pattern mining on said matching data to identify one or more event subsequence patterns that occur in a set of input episodes with a support value above a threshold;
• applying a statistical pattern analyzer to said identified event subsequence patterns to identify one or more correlations between said identified event subsequence patterns and said outcome measure that provide an indication of a degree of informativeness of a given pattern in terms of predicating an episode outcome;
• and
• visualizing one or more of said identified correlations, wherein at least one of said steps is performed by at least one hardware device.
