As 2016 got underway, drug costs once again dominated the news, with several high-visibility shifts in prescription drug prices outraging patients, caregivers, and policy makers alike. Despite the publicity these dramatic shifts attracted, many other price changes occurred behind the scenes with little visibility or attention.

To try to shed some light on the problem, the artists normalized over 60,000 formulations of drugs by their active ingredient in an attempt to identify how much we pay for these treatments. The findings confirm numerous studies that show that overall spending on prescription drugs continues to outpace inflation.

Each line segment in this graph represents an individual drug ingredient, showing the shift in cost and utilization over time and telling an amazing story that ultimately touches many patients’ lives. Whether through increased competition driving a price downward, or a medical breakthrough driving usage up, this collage of changes represents thousands of stories about prescription drug use in our healthcare system.

The artists have highlighted just a few of these stories to the right of the figure. While it is clear that the vast majority of medications have risen in costs in the last five years, this figure also features a number of drugs with falling rates of utilization. This conclusion supports Center for Disease Control findings that found a leveling-off and even a reduction in prescription drug usage from 2005-2012.
