To pilot test the feasibility, usability, and preliminary efficacy of the D-SCAN mobile application in cancer patients and caregivers at Duke.

D-SCAN, a digital patient navigator service in the form of a mobile application ("app"), has been designed at Duke, with feedback from Duke Cancer Institute (DCI) patients, caregivers and clinicians (screenshots in Appendix A).3 Its purpose is to facilitate awareness of available Cancer Patient Support Program (CPSP) services at Duke, and to also help patients recognize their unmet symptom management needs by answering questions from the Edmonton Symptom Assessment Scale (ESAS). This novel electronic system helps to connect patients and their loved ones with existing resources tailored to their unique situations, ensuring that no supportive care needs go unaddressed, thus improving patients' lives and their cancer care.

This protocol aims to assess the feasibility, usability, and preliminary efficacy of the D-SCAN mobile application. The app data, along with quantitative and qualitative feedback obtained during the pilot, will inform future development and design of a subsequent efficacy trial.
