Abstract
INTRODUCTION: Hemodialysis (HD) patients are hospitalized nearly twice yearly, and 35% of these patients are rehospitalized within 30-days postdischarge. We hypothesized that monitored oral nutritional supplementation (ONS) during HD treatment may decrease readmissions. METHODS: A cohort of maintenance HD patients, treated at a large dialysis organization, who were hospitalized with a postdischarge albumin of ≤3.5 g/dL, without documented ONS use 90 days prior to the index hospitalization were identified. Individuals who received monitored intradialytic ONS postdischarge were compared to those without receipt of ONS. The outcome of interest was 30-day hospital readmissions. Logistic regression was used to assess the association between ONS receipt and 30-day readmission events, with adjustment for case-mix and laboratory variables. FINDINGS: Of 5479 eligible patients, ONS was prescribed to 1420 individuals. Mean age was 64.6 ± 14.1 (SD) years; median dialysis vintage was 3.9 years. There were 274 (19%) readmissions among ONS recipients vs. 1571 (38.7%) among controls during the 30-day follow-up period. Individuals who did not receive ONS had increased odds of readmission [OR 2.26 (95% CI 1.02, 2.53)] in 30 days, as compared to those who did receive ONS postdischarge. In sensitivity analyses using a propensity score matched cohort, the odds ratio of readmissions within 30 days postdischarge was 1.71 (95% CI: 1.42, 2.07) for individuals who did not receive ONS as compared to those who received ONS. DISCUSSION: Consumption of ONS during HD sessions is associated with reduced hospital readmission rates among in-center maintenance HD with severe hypoalbuminemia at 30 days post-hospital discharge.
