Detailed Description
This observational study will evaluate bioimpedance spectroscopy (BIS) measurements from patients undergoing hemodialysis. If changes in BIS parameters correlate with changes in fluid volume and patient symptoms, BIS may help provide a non-invasive way to estimate the amount of fluid to dialyze during a hemodialysis session. Data from this study may be used to inform the design of a future interventional trial of BIS use in hemodialysis patients.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Stable hemodialysis regimen Up to 50 patients on hemodialysis >6 months, with stable target/dry weight, and have not been hospitalized recently |
Device: Bioimpedance spectroscopy (BIS) measurement, SOZO device
All patients enrolled in this study will undergo BIS measurement before and after 12 hemodialysis sessions (pre-dialysis and post-dialysis BIS measurements for each session). Measurements are not provided to treating physicians and are not used to guide clinical decisions; i.e., BIS measurements are collected for observational purposes only.
|
| Unstable hemodialysis regimen Up to 20 patients who have been on hemodialysis <6 months, or have unintended weight loss/gain, or have recently been hospitalized |
Device: Bioimpedance spectroscopy (BIS) measurement, SOZO device
All patients enrolled in this study will undergo BIS measurement before and after 12 hemodialysis sessions (pre-dialysis and post-dialysis BIS measurements for each session). Measurements are not provided to treating physicians and are not used to guide clinical decisions; i.e., BIS measurements are collected for observational purposes only.

Outcome Measures
Primary Outcome Measures
- BIS correlation with amount of fluid dialyzed [12 hemodialysis sessions (over 4 to 6 weeks)]
BIS-measured fluid change (volume) will be analyzed for correlation with the volume of fluid removed during hemodialysis as documented on dialysis treatment records.
Eligibility Criteria
Criteria
Inclusion Criteria:

-
Able and willing to remove shoes and stand on SOZO for BIS measurements;
-
Able to provide written informed consent and authorization to use and disclose health information.
Exclusion Criteria:
-
Is enrolled in a concurrent interventional study of an experimental treatment that may confound the results of this study, in the investigator's opinion;
-
Has a clinical condition that would not allow them to complete the study;
-
Is pregnant or planning to become pregnant; women of childbearing potential (or premenopausal) must be on 2 forms of contraception;
-
Is lactating;
-
Has an implanted cardiac rhythm management device (pacemaker or implantable cardioverter defibrillator);
-
Has an amputation of a limb/s resulting in them being unable to make contact with the SOZO electrodes (amputations of fingers and toes are not an exclusion);
