Advanced outcomes research methodologies are necessary to satisfy the increasing interaction between clinicians, epidemiologists, economists, and statisticians. A communication tool to convey information clearly and effectively through graphical means has become a necessity. Patients can switch medication numerous times during the course of treatment and the patterns in which these switches occur can be difficult to illustrate by tables or tree diagrams, especially when analyzing several years of data and various medication switches. With STATinMED’s analytic data visualization tool (ADataVIZ), Patient treatment paths are presented graphically with lines representing the proportion and direction of drug switches, while clicking on specific medications provides additional information about the number of patients who switched, and the linkages between specific drugs. Other information, such as median time to drug switch or outcomes such as mortality, health care costs and utilization and complication rates of a patient group, can also be layered on the paths.
