Introduction:

Clinical Trender is a plugin/cell still in the alpha stages that allows researchers to follow a cohort and properties of a cohort over time.

Downloads:  Clinical Trender is available from the Google Code project http://code.google.com/p/i2b2-clinical-trender/

What the Clinical Trender can do:

• Given a previously identified i2b2 Patient Set, show how that set has grown monthly over several years.
• Given a previously identified i2b2 Patient Set and an individual concept from the ontology tree, show occurrence distribution over time of that concept in the cohort.
• Given a previously identified i2b2 Patient Set and an individual concept from the ontology tree, show concept value distribution over time of that concept in the cohort.
• Concept values will pull from either tval_char or nval_num as defined.

What the Clinical Trender can not yet do:

• Analyze multiple concepts or a folder of concepts at once.
• Analyze concepts that are not traditional concept_dimension queries, this means age calculations and dimensional queries into the patient_dimension, visit_dimension, provider_dimension will cause errors.
