====== Pharmacovigilance evidence investigation Workgroup  ======

<WRAP box justify round>

**Objective:** The objective of this workgroup (WG) is to establish an open-source standardized knowledge base for the effects of medical products and an efficient procedure for maintaining and expanding it. For a complete overview, please see the paper [[http://www.ncbi.nlm.nih.gov/pubmed/24985530|Bridging islands of information to establish an integrated knowledge base of drugs and health outcomes of interest]]. In 2015/16 the WG contributed LAERTES (Largescale Adverse Effects Related to Treatment Evidence Standardization) -- a system that integrates several sources of evidence investigating the association of drugs and health into a single system. The first staging release of LAERTES occurred last year and is reported in https://jbiomedsem.biomedcentral.com/articles/10.1186/s13326-017-0115-3. 

One of the primary use cases for the WG has been the creation of negative controls. Members of the WG published a paper reporting on the accuracy of automated negative control generation using machine learning and the merged evidence base: http://dx.doi.org/10.1016/j.jbi.2016.12.005 

The current efforts of the WG are focused on improving the process of creating and maintaining the merged evidence base, providing better support in OHDSI tools for negative control generation, and developing user friendly methods for using the merged evidence base to investigate pharmacovigilance signals. Other use cases are also being discussed. The new merged evidence base is called the Common Evidence Model and is accessible by requesting data from the project leads. The WG plans to make the data accessible from the OHDSI Web API by April 2018 (see https://goo.gl/1m6NcB).
