Interventions to improve adverse drug reaction reporting: A scoping review.

PURPOSE

Underreporting is the major limitation of a voluntary adverse drug reaction (ADR) reporting system. Many studies have assessed the effectiveness of different interventions designed to improve ADR reporting. The aim of this study was to systematically map interventions and strategies to improve ADR reporting among health care professionals.

METHODS

The six-stage methodological framework of Arksey and O'Malley was used to conduct this scoping review. Ovid MEDLINE, EMBASE, All EBM, and Web of Science were systematically searched from 1999 to February 2019, and the reference lists of the included papers were also searched for gray literature to identify any interventions and strategies that aimed to increase ADR reporting. Two reviewers screened the papers for eligibility based on the inclusion criteria and extracted their key data and analyzed them descriptively.

RESULTS

Ninety out of 14 501 papers met the selection criteria. Using computerized registration and active surveillance can increase ADR reporting significantly. Educational interventions performed individually or combined with sending reminders and/or feedback, awards, and providing easier reporting channels can improve ADR reporting over a short to medium term. Multiple interventions may have more impact than single-component interventions.

CONCLUSION

Multiple interventions could cause a greater increase in ADR reporting rates than single interventions. Although educational interventions appear to be effective, few studies have reviewed their long-term effects to ascertain whether the improvements are sustained over time. Studies with a better methodological quality are required on this subject.
