What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to test a new toilet device that automatically tracks fluid output from hospital patients. The goal is to determine if it can measure urine and stool as accurately as manual measurements by nurses. Participants will either use this special toilet device (Electronic Device for Toilet) or have their output measured by nurses using standard methods. The trial seeks patients scheduled for a stem cell transplant at the Duke ABMT clinic who can read and write in English. As an unphased trial, it offers patients the opportunity to contribute to innovative healthcare technology that could enhance hospital care.

Do I need to stop my current medications for this trial?

The trial information does not specify whether you need to stop taking your current medications. It seems focused on monitoring fluid output, so it's unlikely that your medications will need to be changed, but please confirm with the trial coordinators.

What prior data suggests that this device is safe for monitoring hospital patients?

Research shows that smart toilet devices, like the one tested in this trial, are generally easy for people to use. A recent study from Stanford examined a similar smart toilet that checks urine and stool for signs of disease. This study found no major safety issues with the device.

Electronic systems that monitor health data are becoming more common and are usually safe for users. These systems operate automatically, collecting data without requiring any special action from participants. This automatic process helps minimize risks or discomfort.

While specific safety data for this trial is not yet available, the safe use of similar devices is encouraging. Prospective participants should know that these types of devices have been used without significant safety problems in other situations. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the automated fluid output tracking device because it offers a new, tech-savvy way to monitor hospital patients' fluid balance. Unlike the standard method where nurses visually assess fluid volumes collected in special containers, this device automatically measures and records output directly from the toilet, reducing human error. This innovation not only saves time for healthcare staff but also ensures more accurate and consistent data collection, potentially leading to better patient care and outcomes.

What evidence suggests that this device is effective for monitoring fluid output?

Research has shown that smart toilet devices, like the one tested in this trial, can effectively track health details such as urine and stool output. These devices use sensors to automatically monitor and analyze health data. A study from Stanford found that these toilets could detect signs of illness by analyzing urine and stool. Another study demonstrated that these systems can accurately measure the amount of waste produced. This trial will compare the automated toilet device, used by participants in the experimental arm, to standard collection methods in the control arm, suggesting that the automated device might reliably track fluid output in hospitals. ^{1 2 3 6 7}
