Chronic kidney disease (CKD) as defined by an estimated glomerular filtration rate (eGFR) of <60 ml/min/1.73 sq. m BSA affects about 20 million Americans. Existing CKD care models are predicated on Adult Primary Care referrals to Nephrology Clinics of patients with this arbitrary CKD staging criterion. Increasing referrals of CKD patients have far surpassed the capacity of Nephrology Clinics. Arguably, since most CKD patients remain stable over the years, Nephrology Clinic visits may represent expensive unnecessary care in the majority of referrals.
