Hospital Price Transparency Visualization
The hospital pricing data released by the Centers for Medicare and Medicaid Services (CMS) contains a lot of information that can be visually depicted in a useful manner to paint a general picture of hospital pricing in the United States. In our visualization, the aim was to present the data at a high level. We calculated price indices for the average charges and the average total payments, at the national, state, and hospital levels, and presented this data on the map and graph. The states on the map are colored based on their price index for covered charges and total payments, with blue indicating lower cost and red meaning higher cost. Within the state, the hospitals are marked based on latitude and longitude and hovering over a the hospital gives the user information on the hospital's pricing in relation to the state averages, with respect to the average costs and payments of the DRGs undertaken by that hospital. Presented also are patients' satisfaction with the hospital, out of a 10 point scale, with 10 being highest satisfaction. In the stacked bar graph visualization, the state average covered charges are placed underneath the state's average total payments, and ordered by increasing average covered charges. In this graph, it is easy to see that while the average total payments stays relatively consistent, the average charges varies widely.
