WHA Information Center (WHAIC) developed Kaavio on the Tableau platform as a way to analyze and visualize the Wisconsin discharge data.  Users can gain crucial insights into areas such as population health, utilization, patient access, geographic distribution and market share for hospitals and freestanding ambulatory surgery centers, and compare them to other facilities based on size or region.

Kaavio users can access the data securely from any web browser.  The intuitive navigation allows more diverse users to access, analyze and understand the data then traditional analytic systems.  For more information please contact Brian Competente (bcompetente@wha.org).

The main dashboard in Kaavio is color-coded and illustrates how a facility's median values compare to other facilities.  Users have the ability to "drill-down" to the publicly available, patient-level detail to better understand observed patterns.


Users can create, save and share custom dashboard data filters for categories such as Primary Diagnosis Category, Principal Procedure Category, MS-DRG, Primary Payer and Patient ZIP code.  With the ability to save custom filters, users can send direct links of the custom filters to other Kaavio users.

Quickly and easily create summaries and graphs by selecting from the measures available in Kaavio, like number of visits, total visit charges, median total visit charges and median length of stay.  Charts are automatically displayed when data ranges are selected by the user. 


Kaavio presents data visually with charts and maps to help users discern trends and patterns.  Users can understand their market share and rapidly identify areas of opportunity in a dynamic business environment. 

Examples of charts and maps available

Historic Trends

Users can easily see the trends in the data from quarter to quarter.  Kaavio includes automatic data extrapolation technology to predict possible trends from historic data in larger data sets.


Patient ZIP Code & Census Block Maps

Built-in ZIP code border maps and miles radius features allow "on-the-fly" data exploration enhanced by embedded links to U.S. Census Bureau information.  The size of the marks on the map is relative to the number of visits.  

Each dot is a pie chart that show the proportion of visits for each of the selected facilities.  Clicking on the dots allows a user to see the number of patients per facility.  Kaavio also provides quick analysis on market share data.

Access any ZIP code's population, median age, race and median household income data in addition to the WHAIC data sets.


To look at a more granular area, Kaavio provides the ability to search by census block groups.  Census block groups are more precise and consistent in population size than a ZIP code.  Typically, block groups have a population of 600 - 3,000 people.  Just like the patient ZIP code map, the size of the marks on the map is relative to the number of visits.


Box & Whisker Charts

Box & Whisker charts illustrate the distribution of total charges.  The median charge is located between the two shaded areas of the chart.   The blue dots outside the whiskers represent charge outliers.  The blue dots can be selected, and users are able to view a detail report to view the elements of the outlier visits.
