COMEX Study for Dialysis Patients (COMEX)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03055299
Recruitment Status : Completed
First Posted : February 16, 2017
Last Update Posted : July 3, 2018

Manisha Jhamb, University of Pittsburgh

Brief Summary:
The goal of the COMprehensive EXercise (COMEX) pilot study is to test feasibility, tolerability and adherence of this novel video-based intra-dialytic chair exercise program for hemodialysis patients over 3 months.

Condition or disease Intervention/treatment Phase
ESRD Other: COMEX intervention Not Applicable

Detailed Description:
The investigators incorporated patient-provider preferences of the key stakeholders, and used a multi-disciplinary team with experts in physical therapy, psychology and nephrology to develop a comprehensive exercise program for HD patients. Aim of this pilot study is to assess the feasibility, tolerability and adherence to COMEX over 3 months and inform design of future randomized controlled trial. A secondary goal is to explore molecular mechanisms in muscle and blood of exercise adaptation in HD patients

Comprehensive Exercise

Primary Outcome Measures :
  1. Recruitment rate [ Time Frame: 3 months ]
    Feasibility will be estimated by calculating the % of eligible participants who consent to participate in the study.

  2. Number of participants with exercise-related adverse events [ Time Frame: 3 months ]
    Tolerability will be measured by assessing exercise related side effects - this will be done by weekly patient interviews and review of medical records

  3. Adherence rate [ Time Frame: 3 months ]
    Adherence will be calculated as % of participants who complete the 3 month COMEX intervention. Also, adherence to exercise will be calculated as % of exercise sessions completed

Secondary Outcome Measures :
  1. Fatigue [ Time Frame: 3 months ]
    Self reported fatigue using Functional Assessment of Chronic Illness Therapy Fatigue (FACIT-F) Fatigue questionnaire will be measured at baseline and at 3 months

  2. Sleep [ Time Frame: 3 months ]
    Self reported sleep using Pittsburgh Sleep Quality Index (PSQI) questionnaire will be measured at baseline and at 3 months

  3. Depression [ Time Frame: 3 months ]
    Self reported depression using Beck's Depression Inventory -II questionnaire will be measured at baseline and at 3 months

  4. Global health [ Time Frame: 3 months ]
    Self reported HRQOL using NIH Patient Reported Outcomes Measurement Information System (PROMIS) Adult Global Health questionnaire will be measured at baseline and at 3 months

  5. Health related quality of life [ Time Frame: 3 months ]
    Self reported HRQOL using Short-Form 36 questionnaire will be measured at baseline and at 3 months

  6. Sleep/Wake Behavior by Actigraphy [ Time Frame: 3 months ]
    Objective sleep and activity will be measured using actigraphy

  7. Physical functioning [ Time Frame: 3 months ]
    Will be measured by Short Physical Performance battery at baseline and 3 months
