Background/Aims: Over one-third of hospital discharges among dialysis patients are followed by 30-day readmission. The first year after dialysis start is a high-risk time frame. We examined the rate, causes, timing, and predictors of 30-day readmissions among adult, incident dialysis patients. Methods: Hospital readmissions were assessed from the 91st day to the 15th month after the initiation of dialysis using a Mayo Clinic registry linkage to United States Renal Data System claims during the period January 2001-December 2010. Results: Among 1,727 patients with >= 1 hospitalization, 532 (31%) had >= 1, and 261 (15%) had >= 2 readmissions. Readmission rate was 1.1% per person-day post-discharge, and the highest rates (2.5% per person-day) occurred <= 5 days after index admission. The overall cumulative readmission rate was 33.8% at day 30. Common readmission diagnoses included cardiac issues (22%), vascular disorders (19%), and infection (13%). Similar-cause readmissions to index hospitalization were more common during days 0-14 post-discharge than days 15-30 (37.5 vs. 22.9%; p = 0.004). Younger age at dialysis initiation, inability to transfer/ambulate, serum creatinine <= 5.3 mg/dL, higher number of previous hospitalizations, and longer duration on dialysis were associated with higher readmission rates in multivariable analyses. Patients aged 18-39 were few (8.3%) but comprised 17.7% of high-readmission users such that a 30-year-old patient had an 87% chance of being readmitted within 30 days of any hospital discharge, whereas an 80-year-old patient had a 25% chance. Conclusions: Overall, 30-day readmissions are common within the first year of dialysis start. The first 10-day period after discharge, young patients, and those with poor functional status represent key areas for targeted interventions to reduce readmissions. (C) 2018 S. Karger AG, Basel
