Availability of secondary healthcare data for conducting pharmacoepidemiology studies in Colombia: A systematic review

Pharmacology Research &Perspectives, Volume 8, Issue 5, October 2020., 2020
Abstract Real‐world evidence (RWE) is emerging as a fundamental component of the post‐marketing evaluation of medicinal products. Even though the focus on RWE studies has increased in Colombia, the availability of secondary data sources to perform this type of research is not well documented.
