Effectiveness of pharmacovigilance: multifaceted educational intervention related to the knowledge, skills and attitudes of multidisciplinary hospital staff

OBJECTIVES: Most educational interventions in pharmacovigilance are designed to encourage physicians to report adverse drug reactions. However, multidisciplinary teams may play an important role in reporting drug-related problems. This study assessed the impact of a multifaceted educational intervention in pharmacovigilance on the knowledge, skills and attitudes of hospital professionals. METHOD: This prospective, open-label, non-randomized study was performed in a medium-complexity hospital in São Paulo, Brazil. The intervention involved four activities: 1) an interactive lecture, 2) a practical class, 3) a pre-post questionnaire administered to professionals on a multidisciplinary team, and 4) educational material. The intervention’s impact on the professionals’ knowledge and skills was assessed using the World Health Organization’s definitions. The intervention’s effect on the professionals’ attitudes was analysed by the prevalence of adverse drug event reports (adverse drug reactions, medication errors, therapeutic failure and drug quality deviations) and the relevance (seriousness and expectancy) of the events. RESULTS: One hundred seventy-three professionals were enrolled. A 70-fold increase in the number of adverse drug event reports was observed during the 12 months post-intervention. The intervention improved the professionals’ form-completion skills (
