Overcoming Challenges with a Pharmacovigilance System

Scientists Discussing And Using Computer Software

My last blog outlined the potential for increased return on investments when pharmacovigilance is implemented. The next blog in this series discusses the best ways to overcome any challenges with new systems.

Looking at a pharmacovigilance system holistically, there are interconnected, interdependent parts. Understanding how those individual parts function independently, as well as their impact on the entire system, is important. Breaking it out we have:

  1. AE/PQC intake/capturing information
  2. Storing the data and processing it (AE database)
  3. Data surveillance (analysis and understanding what the data is telling you)
  4. Reporting (regulatory as ICSRs, aggregate, and sharing information internally and externally with other stakeholders)

Subject matter experts work across or within the components. Supporting the entire system are regulatory, compliance and quality, and technology resources.

The chart below illustrates that while drugs were initially approved for one indication, the post-marketing surveillance of AEs helped identity secondary indications.


There are a host of factors that influence the value of each individual component of the pharmacovigilance system. If one is not working optimally, the system in its entirety will not work to its full potential to render the correct and useful data. As an outcome, there could be a misleading interpretation from the analysis of the pharmacovigilance data.

What can be done to minimize the old “garbage in = garbage out?” First, we must identify and overcome/mitigate the challenges that impact each component of the pharmacovigilance system. It is only then that we can move from a reactive PV system to a proactive one.
