Figure 3: Falls Report Drill-Down Functionality Business intelligence tools offer drill-down functionality, allowing users to transition from aggregate to more granular data via point-and-click. In this example, selection of Duke University Hospital from an initial graphical report of total lab/pathology incidents by hospital populates a pie chart demonstrating the percent contribution of each care unit toward the total number of incidents for Duke University Hospital. From here, selection of a single care area, or slice of the pie, leads to a spreadsheet of individual incident reports for detailed investigation.
