The INCH-HD trial will test if incremental HD preserves the quality of life of patients and families and is a safe, practical, cost effective treatment option.
Kidney failure is a growing public health problem and fatal unless treated with dialysis or transplantation. Haemodialysis is the most common treatment for kidney failure in Australia and globally. Patients find haemodialysis extremely burdensome due to symptoms like fatigue, pain, cramps and poor quality of life that generally equates to <60% of full health. Furthermore, haemodialysis is associated with an extremely high mortality (<50% survive 5 years), particularly in the first 3-6 months of starting haemodialysis, which is likely linked to the rapid loss of patients' own kidney function when starting haemodialysis abruptly at three sessions/week. Observational studies suggest that starting haemodialysis incrementally at two sessions/ week is associated with lower mortality and better preservation of patients' remaining kidney function while offering many patient-important advantages, including dialysis free time and ability to work. However, robust evidence to recommend this incremental approach is lacking.
The INCH-HD study is an investigator-initiated, international, multicentre, prospective, adaptive, randomised, open-label, parallel group, non-inferiority trial. The primary objective of the study is to demonstrate whether incremental HD is non-inferior to conventional HD for the patient-important outcome of quality of life measured using Kidney-specific component of the Kidney Disease Quality of Life - Short Form measurement (KDQOL-SF) at 6 months from dialysis commencement.
The study will recruit a total of 372 participants across HD centres in Australia, and Canada. The outcomes of this trial will will provide urgently needed high quality evidence on whether starting haemodialysis incrementally at two sessions/week compared to the conventional three sessions/week can safely reduce the physical, financial and quality-of life burden on patients, lower early mortality rates and slow loss of kidney function while increasing haemodialysis capacity and reducing costs.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Incremental HD | Experimental | Participants randomised to incremental HD will commence HD twice weekly and continue until an indication for an increase to three sessions/week (trigger point) is reached. |
|
| Conventional HD | Other | Participants randomised to conventional HD will commence HD thrice weekly from the first HD session. |

| Heath related quality of life | This will be measured using Kidney-specific component (KSC) of the Kidney Disease Quality of Life Short Form (KDQOL-SF) V1.3 questionnaire. The KSC is the mean of the 11 domains of the kidney-disease specific items of KDQOL-SF. Scores are transformed onto a 0-100 range, where a higher score reflects a better quality of life. | 6 months |
| Measure | Description | Time Frame |
|---|---|---|
| Residual kidney function (RKF) | Calculated as (creatinine clearance + kidney urea clearance) divided by 2 then corrected for body surface area using the DuBois method (0.20247 x (height in centimetres x 0.725) x (weight in kilograms x 0.425). Expressed as millilitres per minute (ml/min). Expected range 1 ml/min to 20 ml/min, where lower values indicate worse kidney function. | Baseline, 3, 6, 12 and 18 months |
| Measure | Description | Time Frame |

| Patient lifestyle and wellbeing | This will be measured using the Patient-Reported Outcomes Measurement Information System (PROMIS) SF 4a (Ability to Participate in Social Roles and Activities and Satisfaction with Social Roles and Activities) | Baseline, 3, 6, 9, 12, 15 and 18 months |

| Heath related quality of life using EuroQol 5-dimension 5-level (EQ-5D-5L) questionnaire | Heath-related quality of life will be measured using EuroQol 5 Domain 5 Level (EQ-5D-5L) questionnaire. EQ-5D has descriptive and visual analogue scale (VAS). Descriptive system consists of five dimensions mobility, self-care, usual activities, pain/discomfort and anxiety/depression. VAS records patient's self-rated health on vertical visual analogue scale with endpoints best to worst health with 0 being worst and 100 being best health. | Baseline, monthly to 18 months |
