Clinical parameters before and after the transition to dialysis

Area of Science:

• Nephrology
• Clinical Medicine
• Patient Outcomes

Background:

• The transition from chronic kidney disease (CKD) to dialysis initiation is a high-risk period.
• Significant mortality and hospital admissions occur during this transition.
• Understanding pre-dialysis parameter trends is crucial for improving outcomes.

Purpose of the Study:

• To analyze trends in clinical and laboratory parameters during the CKD-to-dialysis transition.
• To identify parameters that predict survival in the first year of dialysis.
• To inform early interventions for better dialysis outcomes.

Main Methods:

• Analysis of de-identified data from the Fresenius Medical Care-CKD Registry.
• Examination of trends from 12 months pre-dialysis to 12 months post-dialysis start.
• Focus on cardiovascular, nutritional, mineral metabolism, and inflammatory markers.

Main Results:

• Parameter trends diverge significantly between patients who survive and those who do not in the first year of dialysis.
• Patients with poorer first-year survival had lower absolute systolic blood pressure (SBP) pre-dialysis.
• A steeper pre-dialysis SBP decline was observed in non-survivors.

Conclusions:

• Pre-dialysis parameter trajectories offer unique insights into the CKD-to-dialysis transition.
• Adverse trends identified pre-dialysis can predict first-year dialysis survival.
• Early detection of negative trends may enable interventions to improve outcomes.
