Background
Adherence to recommended treatment is critical in chronic kidney disease (CKD) to prevent complications and progression to kidney failure. The purpose of this study was to explore the adherence to recommendation of patients with CKD, using the Japan Chronic Kidney Disease Database (J-CKD-DB-Ex).
Methods
We developed clinical questions (CQ) recommendation scoring from Clinical Practice Guidelines for CKD 2018 (see Table). We quantified adherence to each of the 8 component metrics, with metric scores ranging from 0 points (poor adherence to recommendation) to 8 points (meeting recommendation). Kidney failure defined estimated glomerular filtration rates (eGFR) <15 mL/min/1.73m2 or eGFR ≥30% reduction. We evaluated the adherence of CQ recommendations and the decline of eGFR and composite kidney outcomes by the Cox proportional hazards models adjusted for age, sex, and eGFR baseline.
Results
Among 4,455 CKD patients, mean age was 67.2 years, mean eGFR was 54.6 mL/min per 1.73 m2, and women was 46.5 % at baseline. Scores of CQ recommendation of 0-5 points group was 12.0%, 6 points group was 29.3%, 7 points group was 41.1%, 8 points group was 17.6%. 838 composite kidney outcomes occurred, more than 6 points groups were at significantly lower risk (6 points: HR 0.67, 95% CI 0.54–0.83).
Conclusion
Great adherence of CQ recommendations was associated with prevention of complications and progression to kidney failure.
