Relationship between compliance with management target values and renal prognosis in multidisciplinary care for outpatients with chronic kidney disease.

BACKGROUND

Although multidisciplinary care (MDC) is necessary for controlling chronic kidney disease (CKD), its impact on compliance with management target values in the CKD guidelines remains unclear. This study was designed to clarify the relationship between compliance with management target values and renal prognosis in CKD outpatients who received MDC.

METHODS

There were 255 outpatients with pre-dialysis CKD who received MDC. Achievement rates of systolic, and diastolic blood pressure, hemoglobin, uric acid, low-density lipoprotein cholesterol, and hemoglobin A1c values determined according to CKD guidelines were compared before and 12 months after MDC. In addition, after dividing achievement rates of the target values at 12 months after MDC into four groups (A < 30% ≤ B < 60% ≤ C < 80% ≤ D), dialysis initiation and renal survival rates were compared.

RESULTS

There was a significant increase in the overall achievement rate from 62.8 to 69.1% (p < 0.001). The higher the achievement rate after MDC, the lower the dialysis initiation rate (A 72.7%, B 35.3%, C 20.5%, D 8.2%, p < 0.001). There was also a significantly higher renal survival rate (p < 0.001). These findings suggest that MDC for CKD raised awareness of health literacy, and improved the achievement rate of target values. Furthermore, the higher the achievement rate, the later the initiation of dialysis, which led to improvement of renal survival.

CONCLUSIONS

MDC can improve compliance with management target values for CKD, suggesting that it may improve renal prognosis.
