Many patients with advanced chronic kidney disease (CKD) managed in a specialized multidisciplinary clinic start dialysis urgently during hospitalization rather than electively as outpatients. This study aimed to identify risk factors for starting unplanned dialysis among patients with advanced CKD who attended multidisciplinary low-clearance clinics between January 1, 2020, and December 31, 2021. Of these, 175 patients started dialysis: 101 (26.7%) started it urgently, whereas 74 (19.5%) started it electively. Patients with urgent initiation of dialysis received less education, had fewer clinic visits and follow-up and were seen less often in the vascular clinic. In the univariate regression analysis, congestive heart failure significantly increased the risk of acute dialysis. Moreover, the risk increased in patients who did not receive dialysis education. The risk increased in patients who were not seen in a vascular clinic and did not have a vascular access plan. Moreover, high albumin levels at initial presentation to the clinic had a lower risk for elective initiation of dialysis. In the multivariate regression analysis, use of renin-angiotensin-aldosterone system inhibitors and attending a vascular clinic reduced the risk of unplanned dialysis by 73% and 96%, respectively. Acute unplanned initiation of dialysis is common even in CKD patients followed in low-clearance clinics. Early referral to multidisciplinary low clearance clinics, timely education, compliance with timely follow-up periods, and creation of access in patients at risk may reduce hospital admissions, hospital stays, admission to intensive care units, costs, and morbidity in these patients.
