Rationale, Aims, And ObjectivesSpontaneous reporting of adverse drug reactions (ADRs) in hospitals is often under-reported, which may lead to problems in patient management. This study was aimed to assess the effectiveness of a financial intervention based on a fine and a bonus for improving spontaneous reporting of ADRs by physicians in a hospital setting.MethodsThis study was conducted at the First Affiliated Hospital of Zhengzhou University (China). Starting in 2009, a bonus of 20 RMB (Chinese currency) was given for each spontaneous ADR report, and a fine of 50 RMB was given for any withheld ADR report. A time series analysis using autoregressive integrated moving average models was performed to assess the changes in the total number of spontaneous ADR reports between the preintervention period (2006-2008) and during the first (2009-2011) and second (2012-2014) intervention periods.ResultsThe median number of reported ADRs per year increased from 29 (range 27-72) in the preintervention period to 277 (range 199-284) in the first intervention period and to 666 in the second (range 644-691). The monthly number of reported ADRs was stable during the 3 periods: 3.56 ± 3.60/month (95% confidence interval (CI), 2.42-4.75) during the preintervention period, 21 ± 13/month (95% CI, 16.97-25.80) in the first intervention period, and 56 ± 20/month (95% CI, 48.81-62.17) in the second intervention period.ConclusionA financial incentive and ADR management regulations had a significant effect on the increase of reported ADRs.© 2017 John Wiley & Sons, Ltd.
