significantly, from one (range 0–5) before the intervention to four (range
1–17) after it. Moreover, serious ADRs increased 3-fold, and non-previously
described ADRs increased 4.5-fold. None of these significant increases were
observed in the hospitals where the hyperlink was not installed. We also
found a significant increase in daily UFN website visits, from ten before the
intervention to 27 after it (p < 0.001).
Conclusion: The increase in ADR reporting shows that the inclusion of hyperlinks
to online ADR reporting forms is an easy and cost-effective way to
change health professional behaviours with regard to spontaneousADR reports.
