Pharmacoepidemiology—often abbreviated as “PE”—is the discipline that studies the use, efficacy, impact, and safety of drugs and vaccines in real-world settings. Long viewed as a specialty reserved for countries with large electronic databases, it now represents a major opportunity for African health systems.
In a context where decisions must increasingly be based on local evidence, pharmacoepidemiology can play a strategic role in improving the quality of health policies and strengthening the performance of health systems.
- Generate local data useful for decision-making
Many treatment decisions in Africa are still largely based on data generated in very different contexts. Pharmacoepidemiology makes it possible to generate local data on the actual use of medicines and vaccines, which are better suited to the realities of West African populations.
- Strengthening pharmacovigilance and the safety of health products
With the increasing introduction of new vaccines, medicines, and biotechnologies, countries need enhanced safety surveillance capabilities. The PE provides robust methods for detecting, analyzing, and interpreting adverse events under real-world conditions.
- Improving the rational use of medicines
The overuse of antibiotics, self-medication, and the inappropriate use of certain treatments remain major challenges. Pharmacoepidemiological approaches provide a better understanding of prescribing and usage practices, thereby helping to guide corrective strategies.
- Supporting vaccination policies
Assessing vaccine effectiveness in real-world settings is becoming increasingly important for guiding national immunization strategies. Several African countries are already participating in vaccine impact and effectiveness studies that employ advanced pharmacoepidemiological approaches.
- Optimizing resources in times of budget constraints
Healthcare systems must balance multiple priorities. Evidence-based practice helps identify which interventions actually yield the best results in real-world settings, thereby enabling a more efficient use of available resources.
- Supporting the development of pharmaceutical regulations
African regulatory authorities are gradually strengthening their post-marketing evaluation and surveillance capabilities. Pharmacoepidemiology is an essential tool for supporting these modern regulatory functions.
- Making the most of data, even when it's imperfect
Contrary to popular belief, pharmacoepidemiology does not always require massive electronic databases. Appropriate approaches can be developed using:
- of medical records;
- registers;
- investigations;
- of sentinel systems;
- or partial databases.
The main challenge often lies more in the methodological and analytical quality than in the size of the available data.
In the coming years, the growing importance of health data, digitalization, and regulatory requirements is expected to significantly increase the demand for pharmacoepidemiological expertise in West Africa.
With its expertise in epidemiology, real-world data, vaccination, clinical research, and regulatory science, CEHPI positions itself as a partner capable of supporting institutions, programs, and professionals seeking to develop or strengthen their capabilities in this strategic area.
