Lollipops for Healthcare Quality Improvement

The Superstore Sales data that ships with Tableau makes life seem so easy: Numbers like Profit and Sales that go up, up, and up. But we don’t only measure things by how high they go, but also how low. Working with hospital quality data, we have small numbers like infection rates that we want to get even smaller. We have rates like the percentage of patients who receive aspirin on arrival that we want to get larger. And then there are measures like how many medication error events are reported that we of course want to get smaller, but we wouldn’t trust if that number got too small too soon because it might indicate under-reporting.

This is a process post about how I solved this problem for a hospital quality dashboard with some brilliant help, a dose of calculated fields, and a number of iterations. I presented this dashboard at the Tableau Customer Conference last month, and offer up this post as a a contribution to Tableau Design Month.
