Each year the news magazine Elsevier publishes a ranking of Dutch hospitals, based upon around 1400 indicators. Zolabo created an interactive tool to give medical professionals insight into how the researchers determined the end scores.
The app offers three base screens. One with an overview of hospitals, one with an image to show how scores are build up and ease of identifying problems, and the last for more in depth analysis. The tools starts to give you an overview of all hospitals with their ranking on the main domains.
Once a hospital is selected you can view a sunburst diagram showing the results of all the indicators in one image. Using colour you'll see how this hospital scores relatively to others (you can choose to which group you want to compare) and you see how this is reflected in the final scores. Selecting a category in the circle lets you zoom in with a smooth animated transition.
Continue to zoom in and you get to the lowest level: the indicator. This is the actual question the hospitals had to answer and is the source data for this research. An overview gives you the input value and shows how this hospital scores compared to others.
In the last screen you can get a list of indicators which let you compare where the hospital has a high or low scores. You'll instantly get a sense of the values of the scores with the simple bar graphs. You can also compare the score of a single indicator among the different hospitals, this way you see which hospital scores best at a certain category.
An important design factor was the ability for the tool to work well on a tablet. The screen size and touch navigation of the device had to be taken into account. Also performance had to be smooth. Because of the large amount of live-calculation in some cases caching was used to store some of the results for later use.
The app had to be secured behind a login. There are accounts that only give access to some of the data of the app. Altogether it required a custom solution of securing the data. Because the tool is behind a login, its not possible to show a live demo, but hopefully this animation gives you a nice idea.
