Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Provision of signed and dated informed consent form
- Undergoing in-center, thrice weekly hemodialysis for treatment of end-stage-renal-disease
- Greater than 3 months since initiation of dialysis
- Age 18 years or above
- Able to obtain a brachial blood pressure at dialysis and at home
Exclusion Criteria:
- Pregnancy, anticipated pregnancy, or breastfeeding as this will require increase to more than three time a week dialysis and/or preclude use of some classes of blood pressure medications
- Incarceration or institutionalized living which may prohibit measurement of home blood pressure
- Participation in another intervention study that may affect blood pressure
- Patients in whom systolic blood pressure is not measurable (e.g. those with left ventricular assist devices)
- Hypotension: average pre-dialysis systolic blood pressure <100 mmHg over last 2 weeks prior to screening while not taking any blood pressure medications
- Life expectancy <4 months
- Anticipated living donor kidney transplant within 4 months

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Home systolic blood pressure (SBP) <140 mmHg
Participants will be asked to take morning and evening blood pressures every two weeks on a non-dialysis day. Participants will be asked to transmit these measures to the study team at minimum every 2 weeks either via Bluetooth technology, a manual log, telephone call, text message, e-mail, or verbal communication. Assigned intervention will be dry weight adjustment and/or adjustment of standard anti-hypertensive medications. |
Use of standard Anti-Hypertensive medications
Other Names:
The participant's target post-dialysis dry weight is adjusted
|
Active Comparator: Pre-dialysis SBP <140 mmHg
Blood pressures taken in the clinical setting at prior to start of dialysis treatment will be recorded. Assigned intervention will be dry weight adjustment and/or adjustment of standard anti-hypertensive medications. |
Use of standard Anti-Hypertensive medications
Other Names:
The participant's target post-dialysis dry weight is adjusted

Assessed every 2 weeks over 4 months
|
Mean Duration (in Minutes) of Recovery From Dialysis Treatments
Time Frame: Assessed every 2 weeks; Data averaged over 16 weeks
|
Data were reported at study visits every 2 wks, the mean was calculated from the first to the last follow-up visit.
The mean was calculated for each participant, then the overall mean was calculated for each arm.
