Impact of an Educational Intervention on Healthcare Providers Pharmacovigilance Knowledge in Lesotho

Pharmacovigilance (PV) plays a crucial role in ensuring medication safety by monitoring and reporting of adverse drug reactions (ADRs). This study evaluated the effectiveness of an educational intervention aimed at improving healthcare professionals’ knowledge and attitudes towards PV in Lesotho. A pre-post intervention questionnaire-based study was conducted amongst healthcare providers in Lesotho. Prior to the intervention, gaps in PV knowledge and limited formal training were evident among participants. Post-intervention results demonstrated notable improvements in understanding core PV concepts and a positive shift in perceptions regarding ADR reporting responsibilities. Despite these gains, challenges related to complex PV topics and systemic barriers persisted. The findings underscore the importance of structured, context-specific training programs to strengthen PV systems in resource-limited settings. Sustained educational efforts, curricular reforms, and institutional support are essential to enhance ADR reporting practices and promote patient safety in Lesotho.
