Algorithm of patients selected for referral back (BR) to primary care. The patients not meeting the BR criteria are removed on the right-hand side. *Exceptions: - In one case, the nephrologists were worried about the risk of renal decline after an episode of acute kidney injury, despite the patient’s CKD stability, and advised the continued follow up of this patient at the renal clinic. - Three patients did not strictly meet the BR criteria, but were still eligible for referral back; two patients had more severe proteinuria, which was stable for over five years, while one patient had recently started blood pressure medication, but the low complexity of their case allowed their referral back to primary care
