Insights
Chronic kidney disease (CKD) guidelines vary, making comparisons difficult. A global effort is needed to harmonize these guidelines for better patient care and survival.
Area of Science:
- Nephrology
- Public Health
- Medical Guidelines
Background:
- Chronic kidney disease (CKD) presents a global health challenge, impacting patient quality of life and survival.
- Numerous preventive and therapeutic interventions are required for CKD management.
- Existing guidelines from various organizations are complex and challenging to compare comprehensively.
Purpose of the Study:
- To compare five major international CKD guidelines on 41 topics across five key areas.
- To identify similarities and discrepancies in recommendations and evidence levels.
- To highlight the need for harmonization of global CKD guidelines.
Main Methods:
- Utilized the Kidney Disease: Improving Global Outcomes (KDIGO) website for guideline comparison.
- Analyzed recommendations and evidence grading for 41 topics including general clinics, hemodialysis, vascular access, peritoneal dialysis, and chemistries.
- Compared guideline statements, rationale, and evidence levels based on shared literature.
Main Results:
- Guideline groups generally propose similar therapeutic targets for CKD.
- Discrepancies exist in guideline statements, rationale, and evidence grading despite reliance on similar literature.
- The KDIGO website provides a comparative overview of recommendations and evidence levels.
Conclusions:
- There is an urgent need to harmonize existing CKD guidelines to ensure consistency in patient care.
- A global initiative is required to prevent the development of conflicting guidelines.
- Comparative tables of guidelines serve as a foundation for harmonization efforts, which have recently commenced.
Abstract:
Chronic kidney disease (CKD) is a worldwide public health problem with significant comorbidity and mortality. Improving quality of life and survival of CKD patients necessitates a large number of preventive and therapeutic interventions. To resolve these issues several organizations have developed guidelines, which are difficult to compare comprehensively. The Kidney Disease: Improving Global Outcomes website at http://kdigo.org compares five major guidelines. The section 'compare guidelines' covers 41 topics distributed over five major subjects: (1) general clinics; (2) hemodialysis (HD); (3) vascular access for HD; (4) peritoneal dialysis; and (5) chemistries. The tables compare guideline recommendations and the evidence levels on which they are based, with direct links to each of the guidelines. These data show that the different guideline groups tend to propose similar targets, but that nuances in the guideline statements, their rationale, and grading of evidence levels present some discrepancies, although most guidelines are based on the same literature. We conclude that there is an urgent need to harmonize existing guidelines, and for a global initiative to avoid the parallel development of conflicting guidelines on the same topics. The tables displayed on the website offer a basis for structuring this process, a procedure which has recently been initiated by a body composed of the five guideline development groups.
