  • Background

    It is widely accepted that Adverse Drug Reactions (ADRs) have a significant impact on public health, both regarding financial and population health consequences. In Europe it is estimated that 5% of hospitalizations and 179,000 deaths are due to ADRs, while in the United States, studies classify ADRs as the 4th-6th most common cause of death, with 100,000 deaths per year reported in hospitals. Despite their high impact, it should be noted that a big percentage of ADRs is preventable. Consequently, the need for tools that can help timely ADR detection is obvious.

    Pharmacovigilance (PV) is defined as the science and activities relating to the detection, assessment, understanding and prevention of adverse effects or any other drug-related problem. A PV signal is defined as “information on a new or known adverse event that may be caused by a medicine and requires further investigation”. To date, the identification and confirmation of ADR signals is carried out by PV experts without the use of specialized IT systems, typically through the use of several standalone tools. In this process, experts collect data (mainly from scientific literature, clinical trial databases, and reporting systems) and implement several approaches to assess a potential ADR signal.


    PVClinical aims to develop an advanced computational platform to facilitate and automate the implementation of PV procedures, with particular emphasis on exploring potential ADR signals and focusing on integrating such processes into the clinical environment. Nevertheless, the PVClinical platform is not limited to the clinical environment, as it can be exploited by Contract Research Organizations (CRO) and the pharma industry studying drug safety issues, as well as drug monitoring organizations and regulatory authorities such as the Greek National Medicines Agency (EOF), or the European Medicines Agency (EMA).


    Taking into account the relatively low number of Individual Case Safety Reports collected in Spontaneous Reporting Systems (SRSs) and, hence, lack of sufficient data to assess potential ADR signals, the PVClinical platform will gather data from multiple data sources, both conventional (such as SRSs and bibliographic databases) and emerging (e.g. Electronic Health Records, Social Media) in the domain of PV. In particular, a key element of the proposed approach is the integration of large-scale heterogeneous information sources applying the “big data” paradigm, which have so far been used fragmentarily or not used at all, to develop a unified data model to support PV procedures with advanced IT tools.
