Remote Activity Monitored by Fitbit Charge 3 in Investigating Daily Step and Sleep Data in Participants With Head and Neck Cancer Undergoing Radiation Therapy

PRIMARY OBJECTIVES: I. Determine compliance with remote activity monitoring (RAM) in patients receiving radiotherapy (RT) or chemoradiotherapy (CRT) for head and neck cancer (HNC). SECONDARY OBJECTIVES: I. Evaluate feasibility of recruitment to the Remote Activity Monitoring Pilot (RAMP). II. Investigate patient acceptability of RAM. III. Evaluate compliance with electronic patient-reported outcomes (ePROs) in this patient population. IV. Estimate the change in average daily steps associated with a one-unit change in health score as collected on ePRO analysis (analyze associations between RAM data and ePROs). V. Investigate correlations among step data, quality of life (QOL), and emergency room (ER) visits/hospitalizations.
