NCT05520346

Brief Summary

The purpose of this study is to determine whether a prototype toilet device that we have developed can accurately and automatically track human fluid output from renal and gastrointestinal systems in the hospital. The device includes components that can be outfitted onto existing toilets. In this study, participants' hospital rooms will be outfitted with the prototype toilet device. Participants will use the toilet as usual throughout the duration of their inpatient stay. Sometimes output will be measured by the device, and other times output will be measured manually by nurses.

Outcome Measures

Primary Outcomes (1)

  • Mean absolute error of urine volume (in mL) as measured by device compared to standard of care nurse assessment

    Up to 14 days

Secondary Outcomes (10)

  • Correlation between daily patient fluid balance (difference between fluid input and output in mL) as measured by device measurements or standard of care nurse assessment and the change in daily weight

    Up to 14 days

  • Mean absolute error of urine volume (in mL) as measured by device

    Up to 14 days

  • Time (in mins) spent handling/recording patient waste

    First 3 days of patient's HCT conditioning

  • Levels of chemotherapy drugs detectable on room surfaces as measured by surface testing

    First 3 days of patient's HCT conditioning

  • Time (in mins) between nurse logging of patient urination in electronic medical records and device-based logging of patient urination

    Up to 14 days

  • +5 more secondary outcomes

Study Arms (2)

Device

EXPERIMENTAL

Patients use toilet device to measure fluid output and self-report event types

Device: Electronic Device for Toilet

Control

NO INTERVENTION

Collection in standard hats + nurses visually assessing fluid volumes

Interventions

Device will be installed on toilet of patients will in hospital to measure all waste output.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
