Abstract
BACKGROUND: Underreporting is a common problem with spontaneous adverse drug reaction (ADR) reporting. In this study, we aim to describe the reporting of ADRs in a tertiary hospital and determine the effect of incentives to healthcare professionals on ADR reporting. METHODS: In this interventional study, a time series analysis was used to determine the effect of incentives on ADR reporting in a tertiary hospital between 2015 and 2016. The incentive strategy included public commendation of health care providers and nomination for a monthly award. RESULTS: A total of 967 ADRs were reported over a 2-year period. After the introduction of incentives in January 2016, the number of ADR reports per month increased by 40.6 (95% confidence interval: 26.1-55.1). The proportion of serious ADRs reported was significantly higher in 2016 (39/800) than 2015 (0/167) (p < 0.001). In 2016, there was a significant association between profession and serious ADR reporting (p < 0.001). A total of 14/21 ADRs (66.7%) reported by physicians in 2016 were serious compared with 20/700 (2.9%) reported by clinical pharmacists and 5/72 (6.9%) by nurses. CONCLUSIONS: ADR reporting was improved by providing incentives, including commendation and reward, to healthcare professionals.
