Comprehensive capture of Adverse Events (AEs) is crucial for monitoring for side effects of a therapy while assessing efficacy. For cancer studies, the National Cancer Institute has developed the Common Terminology Criteria for Adverse Events (CTCAE) as a required standard for recording attributes and grading AEs. The AE assessments should be part of the Electronic Health Record (EHR) system, yet, due to patient-centric EHR design and implementation, many EHRs dont provide straightforward functions to assess ongoing AEs to indicate a resolution or a grade change for clinical trials.
