Effectiveness Of Asco'S Adverse Event Reporting Decision Aid: Results From An Interventional Study.

3065 Background: Investigators often send adverse event (AE) reports to sponsors that are incorrectly categorized as serious or attributed to the investigational drug. Such errors contribute to a high volume of uninformative IND safety reports that sponsors submit to FDA and all participating investigators, straining stakeholder resources and impeding the detection of valid safety signals. To improve the quality of AE reporting, ASCO developed and tested a Decision Aid Tool (DAT). Methods: An interventional study with a cross-over design was conducted. Physician investigators and research staff were randomized to receive case studies. Cases were assessed for seriousness and attribution, first unassisted and then with the DAT. Participants completed a feedback survey. Effectiveness of reporting and attribution were assessed using logistic regression. Results are reported as odds ratios (OR) with 95% confidence intervals (CI). Results: Most of the 29 participants reported that the DAT was helpful (93%), improved their decision-making time (69%) and confidence in reporting (83%), and that they would use it in practice (83%). The DAT did not significantly affect accuracy of determining seriousness (OR, 0.87; 95% CI: 0.31, 2.46) but it did significantly increase accuracy of attributing a serious AE to a drug (OR, 3.60; 95% CI: 1.15, 11.4). Conclusions: The DAT shows promise as a method to reduce errors in attribution of AEs, which may help to ensure the detection of valid safety signals. Many participants were experienced clinical trialists, and the DAT may show greater utility as an educational tool for novice investigators, research staff, and students.
