Pharmacovigilance and Adverse Drug Reaction Reporting among the General Public in Lithuania: A Cross-Sectional Study.

: Despite the fact that for over ten years, Lithuanian consumers have been able to report adverse drug reactions (ADR) directly to the competent authority, reporting rates remain low. A comprehensive understanding of consumer perceptions and experiences regarding ADRs is needed to ascertain further factors impacting their engagement in ADR reporting. This study aimed to assess consumer knowledge of, attitude toward, and practice of reporting ADRs. : A questionnaire-guided cross-sectional survey among 404 consumers between October 2021 and June 2022 was conducted. The semi-structured questionnaire comprised open-ended and closed-ended questions to explore the sociodemographic characteristics and general knowledge of ADRs and pharmacovigilance. Other question items evaluated attitudes toward ADR reporting and ADR reporting practice. The data were summarised using descriptive statistics, while the chi-square test was used to assess categorical variables at < 0.05. The overall percent score in the knowledge and attitude domains was divided into groups of "poor", "moderate", and "good" knowledge, as well as "positive" and "negative" attitudes. : While having a generally poor understanding, this study demonstrates that Lithuanian consumers have a favourable attitude toward pharmacovigilance, particularly regarding issues involving the requirement for reporting. The data also revealed the justifications for reporting and not reporting ADRs. : The current study provided the first understanding of consumer awareness and ADR reporting intentions, which can help to develop educational campaigns and interventions addressing pharmacovigilance and ADR reporting.
