Testing a Device for Automatically TRacking Urine and STool in an Inpatient HCT Setting (Project TRUST)

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.
