Health-related Quality of Life in 10 years Long-term Survivors of Chronic Kidney Disease: A From-J Study.

OBJECTIVE

The Chronic Kidney Disease (CKD) practice facilitation program in the Frontier of Renal Outcome Modifications in Japan study reduced cardiovascular disease (CVD) events in patients with CKD. 10-year long-term survivors with CKD lived with serious complications, including end-stage kidney disease and CVD. This study aimed to measure health-related quality of life in 10-year long-term CKD survivors and examine the predictors and determinants of clinical indices for measured quality of life (QOL) scores.

METHODS

The EQ-5D-5L, a generic preference-based instrument, was administered to 1,473 CKD survivors enrolled in the Frontier of Renal Outcome Modifications in JapanFrontier of Renal Outcome Modifications in JapanFrontier of Renal Outcome Modifications in Japan study. The 10th-year data collection was performed by either primary care physicians or participants who filled out questionnaires from October 2018 to March 31, 2019.

RESULTS

The response rate was 38.2% (423/1,473). The mean QOL score was 0.893 (95% confidence interval (CI), 0.880-0.906), and the median QOL score was 1.000 (interquartile range (IQR), 0.826-1.000). The mean QOL score in participants with renal replacement therapy was 0.824 (95% CI, 0.767-0.881), and the median was 0.828 (IQR, 0.755-1.000). The mean QOL score in participants with CVD was 0.877 (95% CI, 0.811-0.943), and the median was 1.000 (IQR, 0.723-1.000). The mean QOL score in participants with 50% decline in estimated glomerular filtration was 0.893 (95% CI, 0.860-0.926), and the median was 0.889 (IQR, 0.825-1.000). The decrease in QOL scores with baseline CKD stages was significant according to the Jonckheere-Terpstra test for trend (P = .002). Baseline age, systolic blood pressure, and history of hyperuricemia were significant predictors of 10th-year QOL scores.

CONCLUSION

We suggest that CKD complications negatively affect the QOL scores in 10-year long-term survivors with CKD. CKD guideline-based practices, prevention of end-stage kidney disease/CVD and management of hypertension, diabetes and hyperuricemia, might contribute to future health-related quality of life in patients with CKD.
