ADataViZ™, an analytic-based data visualization tool created by STATinMED Research View our data visualization tool here >> Patients can switch drugs numerous times during the course of treatment. The patterns in which these switches occur can be difficult to illustrate by tables or tree diagrams. ADataViZ™, an analytic-based data visualization tool created by STATinMED Research, makes it easier to see trends in drug treatment through an interactive visualization of pharmacy claims data. From an initial prescription, drug A, the paths patients take during treatment are presented graphically with lines representing the proportion and direction of drug switches. In addition, clicking on specific medications provides additional information about the number of patients that switched, and the linkages between specific drugs. Other information, such as median time to drug switch or health care costs of a patient group, can also be layered on the paths.
