Background: Multidisciplinary care is well established in clinical practice, but its effectiveness in patients with chronic kidney disease (CKD) remains unclear. The aim of this study was to determine whether multidisciplinary care could help to avoid worsening kidney function in patients with CKD.
Methods: This nationwide study had a multicenter retrospective observational design and included 3015 Japanese patients with CKD stage 3-5 who received multidisciplinary care. We assessed the annual decrease in estimated glomerular filtration rate (ΔeGFR) and urinary protein in the 12 months before and 24 months after the start of multidisciplinary care. All-cause mortality and initiation of renal replacement therapy were investigated according to baseline characteristics.
Results: Most of the patients had CKD stage 3b or higher and a median eGFR of 23.5 mL/min/1.73 m2. The multidisciplinary care teams consisted of health care professionals from an average of four disciplines. ΔeGFR was significantly smaller at 6, 12, and 24 months after initiation of multidisciplinary care (all P < 0.0001), regardless of the primary cause of CKD and its stage when multidisciplinary intervention was started. Urinary protein level also decreased after initiation of multidisciplinary care. After a median follow-up of 2.9 years, 149 patients had died and 727 had started renal replacement therapy.
Conclusion: Multidisciplinary care may significantly slow the decline in eGFR in patients with CKD and might be effective regardless of the primary disease, including in its earlier stages. Multidisciplinary care is recommended for patients with CKD stage 3-5.
