The Pill Count Controversy:
Why Counting on Accountability is not Enough
for Measuring Adherence in Trials. 



About this Complimentary Webinar

Researching new therapies that have the potential to revolutionize modern medicine relies on patients taking their medications as prescribed - a requirement that's crucial across all clinical trial phases. Despite the substantial body of evidence refuting the accuracy of pill count emerging, research indicates that this method, a method traditionally used to facilitate drug accountability, is still the primary method sponsors adopt to measure medication adherence.

Watch this on-demand recording featuring adherence experts, Job Van Boven, Associate Professor, University Medical Center Groningen, and Bernard Vrijens, Scientific lead, AARDEX Group to learn:
