[New Developments in CKD-MBD. How to "Thinking Global! Acting Local" for treating CKD-MBD]

Area of Science:

• Nephrology
• Endocrinology
• Clinical Guideline Adaptation

Background:

• Global guidelines like KDIGO 2009 CKD-MBD provide a framework for managing chronic kidney disease-mineral and bone disorder.
• Local adaptation of guidelines is crucial for addressing regional healthcare needs and patient populations.
• The principle of "Thinking Global! Acting Local" guides the implementation of international medical standards.

Purpose of the Study:

• To evaluate the appropriateness of the Japanese Society of Dialysis Therapy's (JSDT) 2012 CKD-MBD guideline adaptation.
• To assess the divergence in parathyroid hormone (PTH) targets and interventions compared to the KDIGO 2009 guidelines.
• To examine the impact of evidence level on clinical guideline recommendations.

Main Methods:

• Comparative analysis of the KDIGO 2009 CKD-MBD guideline and the JSDT 2012 CKD-MBD guideline.
• Review of recommended parathyroid hormone (PTH) targets and parathyroid interventions.
• Assessment of the evidence base supporting divergent recommendations.

Main Results:

• The JSDT 2012 guideline significantly differed from the KDIGO 2009 guideline, particularly in PTH targets.
• JSDT placed a strong emphasis on parathyroid interventions.
• The study questions the basis for these divergent recommendations, suggesting potential reliance on opinion or low-level evidence.

Conclusions:

• The adaptation of global CKD-MBD guidelines by JSDT warrants careful consideration regarding the "Acting Local" principle.
• Divergent recommendations, especially those based on weaker evidence, may impact clinical utility.
• A cautious approach is advised when implementing opinion-based or low-level evidence recommendations in clinical practice guidelines.
