The CARI guidelines. Timing of referral of chronic kidney disease patients to nephrology services (adult).

• Patients with an estimated glomerular filtration rate (eGFR) <30 mL/min per 1.73 m should generally be referred to a nephrology service for assessment and multidisciplinary management of chronic kidney disease (CKD). This is to provide adequate time (at least 3–6 months) for predialysis education, creation of permanent dialysis access and planned initiation of dialysis/ pre-emptive transplantation or alternatively, supportive management and palliation for those who do not wish to or are not deemed suitable for chronic dialysis (Level III evidence).
