Study 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 room 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.

Michael Gill holds a Bachelors of Science in Integrated Science and Mathematics from McMaster University. During his degree he devoted considerable time modeling the pharmacodynamics of promising drug candidates. Since then, he has leveraged this knowledge of the investigational new drug ecosystem to help his father navigate clinical trials for multiple myeloma, an experience which prompted him to co-found Power Life Sciences: a company that helps patients access randomized controlled trials.
