The purpose of this project is to expand the capabilities of the current Patient Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) system and to build a body of knowledge and evidence to support the implementation of the PRO-CTCAE system in multi-site clinical research studies supported by the Institute. The three primary objectives of the contract are to: 1) increase accessibility of the PRO-CTCAE system for cancer patients and researchers; 2) conduct a feasibility study in clinical trial networks;and 3) evaluate shared (patient-clinician) and stand-alone (patient only) models for symptom Adverse Event reporting.
