Brief 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.
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Health-related quality of life score | At baseline, 3 months, and 6 months | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Dialysis adequacy | Up to 6 months | Mean single-pool Kt/V (for thrice-weekly) or weekly Kt/V incorporating residual kidney clearance (for twice-weekly). |
| Residual urine output | Up to 6 months | Mean daily urine volume (mL/day) in patients with residual kidney function. |
| Hospitalization rate | Up to 6 months | Proportion of patients requiring hospital admission during follow-up. |
| Interdialytic weight gain | Up to 6 months | Mean interdialytic weight gain (kg). |
| Mortality | Up to 6 months | Proportion of patients who die during the follow-up period. |
