Pain Management Smartphone Application for Patients With Stage III-IV Head and Neck Cancer Undergoing Radiation Therapy

PRIMARY OBJECTIVES: I. Obtain consumer input to determine the optimal way to address and monitor the patient's symptoms. II. Train patients to use the pain management smartphone application (PMSA) and determine the compliance characteristics and the number of additional on-treatment visits (OTVs) prompted by usage of the application. OUTLINE: Selected patients are interviewed for input that will help guide the wording of questions of the PMSA. All patients/caregivers are then instructed to download the PMSA and are demonstrated how to properly use the application. Beginning on the first day of radiation therapy (day 1), patients are instructed to use the PMSA for the duration of their radiation therapy (up to day 50), although the timing may change based on the availability of the app.
