A Behavioral Health Intervention Using Digital Technology in Radiation Therapy for Prostate Cancer Patients

Status: closed to accrual

This clinical trial assesses the use of a smart water bottle to improve bladder filling for prostate cancer patients undergoing radiation therapy. A consistent bladder filling throughout the treatment is important to help improve the quality of cancer treatment. When patients do not have a full bladder during radiation treatments, they may be asked to fill their bladder, which can lead to treatment delays and back up the clinic’s flow. A digital smartphone-based behavioral intervention may coach motivated prostate cancer patients to develop a sensory awareness of an optimally filled bladder, improving their need for re-imaging while on the radiation treatment table and decreasing their overall time in clinic. This study may also help researchers learn more about how to reduce wasted time in the radiation clinic.

Inclusion Criteria

Age older than 18 but less than 80
Non-metastatic prostate cancer patients undergoing definitive radiation treatment
Patients that self-identify as “smartphone owners”
Patients with either iPhone (iOS 13.0 or higher) or Android (version 5.0.1 or higher) based smartphone access
English or Spanish speaking patients

Exclusion Criteria

Patients with any history of pre-existing urinary retention
Patients with any history of kidney, urothelial tract, or bladder cancer
Post-operative prostate patients
Patients that plan to be treated with pelvic lymph node radiation coverage
Patients without a functional bladder
Patients with a history of prior pelvic surgery or penile augmentation (circumcision is okay).
Patients who have previously received any form of pelvic radiation
Patients unable to give informed consent
Patients who refuse to drink room-temperature water used for bladder filling
Patients without functional vision
Patients who are colorblind
Patient who refuses to use the smartphone app or who refuse consent

PRIMARY OBJECTIVE:

I. Determine feasibility in adoption of a digital health intervention for bladder volume compliance.

SECONDARY OBJECTIVES:

I. Determine feasibility in adoption of a digital health intervention for bladder volume compliance based on patients’ survey.

II. Determine feasibility in adoption of a digital health intervention for bladder volume compliance based on cone-beam computed tomography (CT).

III. Identify barriers for implementation of qualitative and quantitative metrics of bladder filling compliance.

IV. Assess patient’s perception of bladder filling compliance.

V. Assess patient attitudes towards digital health behavioral interventions.

VI. Assess screen failure rate.

OUTLINE:

Patients receive a Hidrate Spark 3 smart water bottle, and receive visual cues on the water bottle and reminders via the "Hidrate" application (app) to drink 20 oz of room temperature water 45 minutes prior to their CT simulation. Patients then receive reminders to drink 20 oz of room temperature water 45 minutes prior to their scheduled daily radiation treatments 5 days per week and undergo cone beam CT prior to their treatments.
