Abstract
Background: In the context of the growth of pharmacovigilance (PV) among developing countries, this systematic review aims to synthesise current research evaluating developing countries' PV systems' performance.
Methods: EMBASE, MEDLINE, CINAHL Plus, and Web of Science were searched for peer-reviewed studies published in English between 2012 and 2021. Reference lists of included studies were screened. Included studies were quality assessed using Hawker et al.'s nine-item checklist; data were extracted using the WHO PV indicators checklist. Scores were assigned to each group of indicators and used to compare countries’ PV performance.
Results: Twenty-one unique studies from 51 countries were included. Of a total possible quality score of 36, most studies were rated medium (n = 7 studies) or high (n = 14 studies). Studies obtained an average score of 17.2 out of a possible 63 of the WHO PV indicators. PV system performance in all 51 countries was low (14.86/63; range: 0-26). Higher average scores were obtained in the 'Core' (9.27/27) compared to 'Complementary' (5.59/36) indicators. Overall performance for 'Process' and 'Outcome' indicators was lower than that of 'Structural'.
Conclusion: This first systematic review of studies evaluating PV performance in developing countries provides an in-depth understanding of factors affecting PV system performance.
