The Study Buddy ECA acts as an advisor to patients on chemotherapy regimens, promoting protocol adherence and retention, providing anticipatory guidance and answering questions, serving as a conduit to capture information about complaints or adverse events, providing a venue for communicating about updates. The Study Buddy will use the web-based ECA infrastructure developed for use on another project. We will use web browsers on tablets provided to study participants to access the Study Buddy, providing anywhere, anytime access to its functions. Usability metrics will include session time, satisfaction, and error rates.
