Why is it important?

The Medication Possession Ratio (MPR) is a ubiquitous and central measurement for adherence in the health care industry. However, attempts to standardize its calculation have failed, possibly due to the opacity of a single, static MPR, incapability of directly lending itself to a variety of studies, and challenges of comparing the value across studies. This work proposes a novel approach to calculate a MPR trend over a range of time intervals developing an upper and lower bound of the MPR trend.
