Change History
Current Secondary Outcome Measures  ICMJE
 (submitted: October 27, 2017)
  • Poorly controlled pre-dialysis blood pressure [ Time Frame: 4-week intervention period ]
    Number of participants with ≥30% of dialysis sessions with pre-dialysis systolic BP > 160 mm Hg
  • Dialysis Tolerability [ Time Frame: 4-week intervention period ]
    Number of participants with ≥30% of dialysis sessions with post-dialysis weight > prescribed dry weight or delivered length of dialysis < prescribed length. We will also assess dialysis symptoms using the Dialysis Symptom Index.
Original Secondary Outcome Measures  ICMJE Same as current
Current Other Pre-specified Outcome Measures
 (submitted: October 27, 2017)
44-hour ambulatory blood pressure [ Time Frame: Final week of the 4-week intervention period ]
Compare the number of hours spent in the desired systolic BP range of 110-150 mm Hg in patients in TAKE versus HOLD units. We will also compare the number of patients who demonstrate nocturnal dipping patterns of BP in the TAKE and HOLD units.

Descriptive Information

Official Title  ICMJE Timing of Antihypertensive Medications on Key Outcomes in Hemodialysis
Brief Summary For patients with kidney failure requiring hemodialysis treatment, sometimes the blood pressure will drop too low during dialysis. In an effort to prevent that from occurring, patients are frequently told to skip doses of their blood pressure medications. However, whether this actually prevents blood pressure drops during dialysis, and whether it may cause more uncontrolled high blood pressure is unknown. TAKE-HOLD will study the effect of taking or holding blood pressure medication on blood pressure for patients on hemodialysis.
Detailed Description High blood pressure (BP) is a major modifiable risk factor for cardiovascular disease, and upwards of 90% of patients with end- stage renal disease (ESRD) have high BP. Appropriate BP management, therefore, is a fundamental part of patient care in ESRD, yet the question of when best to take antihypertensive medications relative to the hemodialysis treatment session remains unanswered. Many patients on hemodialysis suffer from an abrupt fall in BP during the dialysis session (i.e., intradialytic hypotension [IDH]), a phenomenon that is associated with numerous adverse outcomes. In an attempt to minimize IDH, patients are often told to withhold antihypertensive medications prior to hemodialysis, and current guidelines suggest taking antihypertensive medications at night to minimize IDH. However, there are no data regarding the safety of these antihypertensive medication timing strategies, or whether these strategies are effective in reducing IDH.
Study Type  ICMJE Interventional
Study Phase  ICMJE Not Applicable
Study Design  ICMJE Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description:
Cluster randomized parallel group trial
Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE
  • ESRD
  • Hemodialysis Complication
  • Blood Pressure
Intervention  ICMJE Behavioral: TAKE vs. HOLD
All participants will be told to take once daily antihypertensive medications at night. Timing of other antihypertensive medication administration will differ depending on whether the participant is randomized to the TAKE or HOLD arm.
Study Arms  ICMJE
  • Experimental: TAKE
    Participants in TAKE units will be advised to take all antihypertensive medications as prescribed, including on the morning of dialysis.
    Intervention: Behavioral: TAKE vs. HOLD
  • Experimental: HOLD
    Participants in the HOLD units will advised to hold the dose of the antihypertensive medications prior to the dialysis session on the morning of the dialysis days. Participants can choose whether they wish to take the antihypertensive medication that was held at any time after the dialysis session has ended.
    Intervention: Behavioral: TAKE vs. HOLD
