Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the impact of the optimal and late initiation of dialysis on the mortality and quality of life in end-stage renal disease (ESRD) patients by the Dialysis Initiation based on Fuzzy mathematics Equation (DIFE), which is a novel equation for the assessment of timing of dialysis initiation established by Fuzzy mathematics.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The optimal time of dialysis initiation is still controversial. Estimated glomerular filtration rate (eGFR) which is now widely used as the assessment of timing of dialysis is lack of specificity. Some clinical factors such as heart failure, volume overload, malnutrition also determine the dialysis time. But these subjective judgements do not have a standard. So there is no quantitative assessment of timing of dialysis initiation. The research team developed a novel equation named DIFE (Dialysis Initiation based on Fuzzy mathematics Equation) with data from a retrospective multicenter cohort by fuzzy mathematical methods to combine these clinical factors and lab indexes. The DIFE was confirmed to be more accurate and convenient to use in clinical practice than eGFR only at the assessment of dialysis initiation time in the internal validation. For further validation of the DIFE, the team will conduct a multicenter randomized controlled trial. Patients who need hemodialysis will be randomized to optimal start dailysis group or late start dailysis group by the assessment of the DIFE. Based on the comparison of the two groups, this trial will provide evidence for the optimal timing of dialysis initiation in patients with end-stage renal disease by the DIFE.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

optimal start dialysis group

The DIFE will be used as the assessment of initiation time of dialysis. Patients in this group will start dialysis when their results of the DIFE reaching to 30-35, which defined as the optimal start time.

Group Type EXPERIMENTAL

optimal start time

Intervention Type OTHER

patients will start hemodialysis when their DIFE reach 35, and can not wait if the DIFE decline to 30.

late start dialysis group

the DIFE will be used as the assessment of initiation time of dialysis. Patients in this group will start dialysis when their results of the DIFE less than 30, which defined as late start time.

Group Type ACTIVE_COMPARATOR

late start time

Intervention Type OTHER

patients will start hemodialysis when their DIFE less than 30
