Development and Pilot Implementation of a Remote Monitoring System for Acute Toxicity Using Electronic Patient-Reported Outcomes for Patients Undergoing Radiation Therapy for Breast Cancer.

Purpose: We aimed to develop and study the implementation of a remote system for toxicity assessment and management of acute side effects of breast radiation using electronic patient-reported outcomes (ePROs).

Methods And Materials: A response-adapted Patient-Reported Outcomes Common Terminology Criteria for Adverse Events-based assessment for breast radiation toxicity was administered weekly during and for 8 weeks after radiation from June 2019 to July 2020. The care team received alerts when "severe" symptoms were reported by patients, who were then contacted.
