Web-Based Symptom Monitoring With Patient-Reported Outcomes During Definitive Radiation Therapy With Chemotherapy (SYMPATHY): A Prospective Single-Center Phase 1 Study

PURPOSE: We evaluated the feasibility of patient symptom self-reporting using a web-based interface (WBI), with automated message alerts for severe and/or worsening symptoms, in patients undergoing definitive chemoradiation therapy (CRT). METHODS AND MATERIALS: Patients receiving definitive CRT for gastrointestinal, lung, and head and neck cancers with access to a computer and/or mobile device were eligible. Symptom self-reporting was conducted via a WBI through surveys adapted from the patient-reported outcomes version of the Common Terminology Criteria for Adverse Events: 2 per week during CRT and 1 per week for 3 months after CRT. Nurses were alerted whenever a patient's symptom worsened by ≥2 points or reached a score of ≥3. Patient-Reported Outcomes Measurement Information System (PROMIS) surveys were conducted at baseline, end of CRT, and 3 months after CRT. Patients also completed exit surveys 3 months after CRT. RESULTS: Nineteen patients were enrolled with a median of 30 fractions (range, 28-33). The median survey completion rate was 26% (range, 0%-100%) during CRT and 33% (range, 0%-100%) during the first 3 months after CRT. Five (26%) had acute hospital encounters during CRT or within 3 months of CRT completion. Two patients (11%) experienced CRT treatment interruptions. During CRT, 70 of 81 surveys (86%) were flagged and 61 of 70 (87%) were acted upon by a nurse or physician within 4 days; during the first 3 months after CRT, 47 of 85 (55%) were flagged and 28 of 47 (60%) were acted upon within 7 days. Ninety-two percent of patients found it always easy to access the survey while 58% found the surveys too long or too frequent. None of the PROMIS domains had statistically significant changes during any time points. CONCLUSIONS: Symptom self-reporting via a WBI is feasible during definitive chemoradiation with high patient satisfaction. Survey fatigue is common and may be mitigated by improving the WBI to make it more patient-centered and allowing patients to choose which symptoms to report.
