The Visual Dashboard is a Timeline based display of Patient History. It places the diagnostic, treatment and other interventions, such as surgeries, into an historical context, displaying the sequence and relationships among medical issues as they occur over a range of dates, particularly Date of Onset and End Date, if applicable. Chronic conditions are displayed as open-ended. It supports zooming and scrolling thus it can offer a view of multiple years down to the more granular view of months or weeks. This chronological view offers the advantage of an holistic and synoptic comprehension of a patient’s journey, making it possible to develop hypotheses more quickly than conventional dashboards.
