Brief summary

The purpose of this study is to determine how to incorporate a smart water bottle to improve bladder filling for prostate cancer patients undergoing radiation therapy.

Interventions

Patients will be given a smart water bottle and coached on its use. The device is a 24 oz non-bisphenol A acrylic water bottle with the ability to track water consumption from the bottle, alert its users via a smartphone-based notification system, as well as visually remind patients with a light-emitting diode in the device. Participants will be alerted to drink patient-specific volumes of room temperature water 45 minutes prior to daily standard of care radiotherapy.

Design outcomes

Primary

MeasureTime frameDescription
Proportion of participants who did not continue to use the intervention through the study.Up to 10 weeksProportion of participants will be reported as those who did not continue to use the intervention throughout the study.

Secondary

MeasureTime frameDescription
Proportion of non-compliant participants as measured by bladder volumeUp to 10 weeksNon-compliance to study intervention will be assessed using a cone beam Computerized Tomography (CT) scan of participant's bladder volume
Bladder volumetric measurementsUp to 10 weeksAs measured by cone beam CT scan
Proportion of non-compliant participants as measured by surveyUp to 10 weeksProportion of non-compliant participants via a patient-reported survey.
Patient's perception of bladder filling compliance as measured by Service User Technology Acceptability QuestionnaireUp to 10 weeksPatient reported scores based on Service User Technology Acceptability Questionnaire (SUTAQ) will measure patient's perception of the smart water bottle. SUTAQ has a total score ranging from 20-100 with the higher score indicating increased user acceptability and comfort with the device.
Proportion of patients refusing participationBaselineProportion of screen-eligible participants who refused study participation
Rectum Volumetric MeasurementsUp to 10 weeksAs measured by cone beam CT scan
