Cardiovascular and Renal Outcomes in an Excellent Chronic Kidney Disease Clinic Compared with an Outpatient Clinic in a Primary Care Setting: A Retrospective Cohort Study.

Background: Chronic kidney disease (CKD) is associated with increased cardiovascular morbidity and mortality. In standard care, the physician attempts to control all known risk factors, but treatment goals are achieved with difficulty. Assistance by a multidisciplinary care team may improve outcomes.

Objective: To compare the cardiovascular and renal endpoints between patients with CKD receiving care from excellent CKD and outpatient clinics.

Methods: A retrospective cohort study was conducted in a primary care setting in Thailand. Patients with CKD stages 3 and 4 in excellent CKD ( = 96) and outpatient clinics ( = 192) were matched in a 1: 2 ratio with the propensity score. We collected data from electronic medical records concerning the incidences of primary composite outcomes including rapid renal progression, end-stage renal disease, myocardial infarction, congestive heart failure, stroke, and mortality. Multidisciplinary team care in the excellent CKD clinic consisted of physician, nurse, pharmacist, dietitian, physical therapist, and applied Thai traditional physician. The outpatient clinic consisted of physician care only.

Results: Subjects' mean age was 64.54 ± 10.96 years, and 52.1% were female. During an average 49.63 ± 8.36 months of follow-up, 74 events occurred including 35 (47.30%) patients who experienced renal events, 29 (39.19%) who experienced cardiovascular events, and 10 (13.51%) who experienced loss of life. The Kaplan-Meier curve indicated a higher percentage of subjects without primary composite outcomes in the excellent CKD clinic than those in the outpatient clinic (66.85%; 95% CI 0.48-0.80 vs. 44.71%; 95% CI 0.29-0.60; = 0.005). From multivariate analysis, the excellent CKD clinic group had a 64% lower risk for primary composite outcomes compared with those in the outpatient clinic (adjusted HR 0.36; 95% CI 0.18-0.74; = 0.005).

Conclusion: A multidisciplinary care system can reduce composition outcomes including cardiovascular and renal outcomes for the growing CKD population. The optimal outcomes arise from the medical personnel's teamwork, not from one physician alone.
