Advanced chronic renal failure (ACRF) study. Baseline characteristics, evaluation of the application of the structured information for the election of renal replacement therapy and one-year evolution of the incident patients in the ACRF medical office.

Background And Objectives: Analyze evolution Renal Chronic Failure stage 4-5 (ACRF) patients and influence information they receive (educational process, EP) in modality Renal Replacement Therapy (RRT) or conservative treatment (CT) in multidisciplinar ACRF Office.

Material And Methods: Prospective, multicenter study (3 centers). Inclusion: from June-01-2014 to October-01-2015; observation: 12 months or until start RRT or death if they occur before 12 months; ends October-01-2016.

Results: 336 patients were included (60% males), median and intercuartile rank 71.5 (17), 55% ≥ 70 years; Follow up initiation eGFR CKD-EPI: 21 (9) ml / min / 1.73m; Charlson Index (ChI) with / without age 8 (3) / 4 (2); Diabetic patients: 52,4%. The EP was carried out in 168, eGFR 15 (10) ml / min / 1.73m. The initial treatment election: 26% peritoneal dialysis (PD), 45% hemodyalisis (HD), 26% CT, kidney trasplant 3%; 60 patients started RRT: 3.3% kidney traspant; 30% PD, 66% HD; 104 admissions in 73 patients, the most frequent cause: cardiovascular disease (42%). Fallecimiento: 23 patients (6.8%). Age was higher (78.4 (6) vs. 67.8 (13.4), P<.001), higher ChI 9.8 (2.1) vs. 7.4 (2.5), P<.001). All deceased who received EP had chosen CT; 61% of deceased had at least one hospital admission vs. 39% alive (P<0.001). Cox regression: age and Charlson index were the predictive mortality variables.

Conclusions: The population of ACRF patients is elder, comorbid, with high rate hospitalizations rate. The PD election is higher than usual. The EP has been very useful tool and has favored the PD choice.
