    What is Pharmacoepidemiology?

    Pharmacoepidemiology is the study of the health effects of drugs and other medical products in populations. It is the basic science underlying the public health practice of medical product safety surveillance. Pharmacoepidemiologists apply the research methods of epidemiology (e.g., randomized trials, cohort studies, case-control studies, self-controlled designs) to the study of pharmacology (e.g., determinants of beneficial and adverse drug effects, effects of genetic variation on drug effect, dose-response relationships, duration-response relationships, drug-drug interactions, effects of non-adherence). Pharmacoepidemiologists also evaluate programmatic efforts to improve medication use.

    CPeRT Mission

    The Center for Pharmacoepidemiology Research and Training (CPeRT) was founded in 2012 (although Penn faculty member have been conducting pharmacoepidemiology research since the early 1980s) and is based in the Center for Clinical Epidemiology and Biostatistics (CCEB). Its mission is to:

    • Provide an intellectual home for pharmacoepidemiology at Penn
    • Promote the conduct of applied and methodologic pharmacoepidemiology research
    • Foster training of the next generation of pharmacoepidemiologists
    • Expand number of Penn faculty members performing pharmacoepidemiology research

    CPeRT members are leaders in the development and use of large administrative and medical record databases for studying drug effects. CPeRT is one of the academic partners of the Food and Drug Administration (FDA)-funded Mini-Sentinel Initiative. CPeRT members also edit Pharmacoepidemiology, 5th edition and Textbook of Pharmacoepidemiology.
