Background: Monitoring of toxicity and adherence is often lacking for patients recently started on oral chemotherapy. National guidelines recommend active outreach to patients within a week after treatment start. We developed an online tool to actively reach out to patients newly started on oral chemotherapy at one academic medical center and community practice. Methods: A multi-disciplinary team, including patients, developed an online oral chemotherapy adherence, symptom, and financial toxicity assessment tool within REDCap. We implemented this tool for new oral chemotherapy prescriptions in May 2018 in the gastrointestinal oncology group of an academic medical center and a general community practice. To quantify the impact of this tool on symptom management, we completed a retrospective analysis of patients receiving new oral chemotherapy prescriptions at these same sites, in the 13 months immediately preceding clinical implementation of the online tool, May 2017 to May 2018. Results: In the pre-intervention historical cohort (n = 58) the median time to first symptom assessment by a clinician was 7 days (range 1 – 41 days, SD 7 days), median time to identifying a new or worsening symptom was 10 days (range 1-55 days, SD 10 days), and median time to clinical action regarding a new or worsening symptom was 10 days (range 1-104, SD 20 days). Our first intervention patient used the online tool in May 2018 to report symptoms of “nausea and fatigue,” 4 days after starting oral chemotherapy. This resulted in an oncology clinical nurse calling the patient to review symptom management by phone. Conclusions: The median time to first symptom assessment in our historical control cohort is 7 days, with standard deviation of 7 days, suggesting potential room for improvement. Thus far, the online tool has been completed by one patient. Further data will be reported regarding the uptake of this tool, the tool’s impact on quality measures, and patient reported symptoms, adherence, and financial toxicity.
