Interventions to improve spontaneous adverse drug reaction reporting by healthcare professionals and patients: systematic review and meta-analysis (original) (raw)

The aim of this study was to evaluate the effectiveness of interventions used for improving ADR reporting by patients and healthcare professionals. A systematic review of literature was conducted by searching Medline, Embase and Cochrane Central Register of Controlled of Trials. Meta-analysis of randomised controlled trials (RCTs; n=5) was conducted to estimate the pooled risk ratio for the effectiveness of interventions on ADR reporting rates. Data from observational studies were synthesised using narrative synthesis approach. A total of 28 studies were included. All except one study targeted healthcare professionals using educational, technological, policy, financial and/or mixed interventions. The results showed that financial and face-to-face educational interventions improved quality and quantity of ADR reporting when compared with interventions not involving face-to-face interactions. However, the quality of studies was generally low. Meta-analysis showed a statistically significant 3.5-fold overall increase in reporting of ADRs [RR 3.53; 95% CI (1.77,7.06)] in the intervention group compared to the control. There was a lack of consideration of theory and sustainability in the design of the interventions. There is a need to develop and test theory-based interventions and target patient reporting. More research needs to be conducted in the low-and-middle-income countries.
