Using mobile and sensor technology to identify early dehydration risk in head and neck cancer patients undergoing radiation treatment: Impact on symptoms.

6063Background: Assessment and intervention with mobile and sensor technology may improve early detection and mitigation of treatment-related symptoms, impact quality of life (QOL), reduce complications, and lower health care costs. The CYCORE (CYberinfrastructure for COmparative effectiveness Research) system utilizes sensor and mobile technology to remotely assess daily weight, blood pressure (BP)/pulse, and patient-reported outcomes in head and neck cancer (HNC) patients undergoing radiation treatment (RT). Clinicians reviewed data daily to identify early risk of dehydration and support early intervention to improve symptom management. We compared longitudinal symptom data in patients randomized to use CYCORE during RT versus those randomized to usual care. Methods: Methods: HNC patients (n = 357) completed the 28-item MD Anderson Symptom Inventory (MDASI) at RT initiation (baseline), completion of RT (6-7 weeks post-baseline), and 6-8 weeks post-RT completion. Symptom severity and interference were ra...
