Causality in Pharmacoepidemiology and Pharmacovigilance: a theoretical excursion.

Abstract

The article presents some considerations about causality in Pharmacoepidemiology and Pharmacovigilance. To begin, we provide a brief introduction about the importance of the issue, noting that the understanding of causal relationships is considered one of science's greatest achievements and has been, over time, a continuous and central concern of philosophers and epidemiologists. Next, we describe definitions and types of causes, demonstrating their influences on pharmacoepidemiological thought. After that, we present Rothman's multi-causal model as one of the founding explanations of multiple causality and the issue of causality assessment. We conclude with some comments and reflections on causality from the perspective of health surveillance, particularly with regard to regulations on pharmacovigilance.
