Study summary

This prospective cohort study aims to compare clinical outcomes and health-related quality of life between adults receiving established twice-weekly versus thrice-weekly maintenance hemodialysis at Assiut University Hospitals.

Read the detailed description

Thrice-weekly maintenance hemodialysis is the conventional schedule. Twice-weekly hemodialysis is used selectively in patients with residual kidney function. Local prospective comparative data in Egypt are limited.

This observational study will include adults with end-stage kidney disease receiving established twice-weekly or thrice-weekly in-center maintenance hemodialysis. Patients will be followed according to their prescribed schedule without research-driven changes. Health-related quality of life will be assessed using the Arabic KDQOL-36 at baseline, 3 months, and 6 months. Clinical outcomes including adequacy, residual kidney function, hospitalization, and mortality will be recorded.

Study population

Adults with end-stage kidney disease receiving maintenance in-center hemodialysis at Assiut University Hospitals.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • - Age 18 years or older
  • Established end-stage kidney disease requiring maintenance hemodialysis
  • Receiving in-center maintenance hemodialysis at Assiut University Hospitals
  • On maintenance hemodialysis for at least one month before enrollment
  • Established twice-weekly or thrice-weekly schedule prescribed by the treating team
  • Clinically stable at recruitment
  • Able to understand and respond to the questionnaire
  • Written

Exclusion criteria

Exclusion Criteria:

  • - Acute kidney injury without established end-stage kidney disease
  • Hemodialysis for less than one month
  • Peritoneal dialysis or kidney transplantation during follow-up
  • Acute severe illness requiring intensive care at recruitment
  • Severe cognitive, psychiatric or neurological impairment preventing reliable questionnaire responses
  • Active with expected survival too short to complete follow-up
  • Temporary dialysis solely for an acute indication
  • Refusal to participate
  • Permanent transfer to another dialysis center during follow-up
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

What researchers measure

Primary outcomes

  1. Health-related quality of life score

    Mean total score of the Arabic Kidney Disease Quality of Life-36 (KDQOL-36) questionnaire. The KDQOL-36 score ranges from 0 to 100; higher scores indicate better health-related quality of life.

    Time frame: At baseline, 3 months, and 6 months

Secondary outcomes

  1. Dialysis adequacy

    Mean single-pool Kt/V (for thrice-weekly) or weekly Kt/V incorporating residual kidney clearance (for twice-weekly).

    Time frame: Up to 6 months

  2. Residual urine output

    Mean daily urine volume (mL/day) in patients with residual kidney function.

    Time frame: Up to 6 months

  3. Hospitalization rate

    Proportion of patients requiring hospital admission during follow-up.

    Time frame: Up to 6 months

  4. Interdialytic weight gain

    Mean interdialytic weight gain (kg).

    Time frame: Up to 6 months

  5. Mortality

    Proportion of patients who die during the follow-up period.

    Time frame: Up to 6 months
