Abstract 16047: Trends in Usage and Outcomes Associated With Ultrafiltration in Hospitalized Patients With Congestive Heart Failure
Introduction: Congestive heart failure is a leading cause of inpatient admissions and readmissions. We sought to analyze the outcomes related to use of ultrafiltration in such patients and assess its effects on length and cost of hospitalization in a large national database.
Methods: We utilized Nationwide Inpatient Sample database 2005-2012 which is a 20% discharge sample of all hospitalizations across the United States. We divided the patients admitted with congestive heart failure into those underwent ultrafiltration versus those did not. Univariate and multivariate analyses were performed for mortality, length and cost of hospitalization.
Results: A total of 3,789,452 patients were included in the analysis out of which 1833 (0.05%) patients underwent ultrafiltration. The rates of ultrafiltration have increased significantly from 2005 to 2012 but the overall percentage of patients undergoing ultrafiltration in a year has remained low (0.01% vs 0.1%, p<0.001). Males and patients with acute kidney injury or chronic kidney disease were more likely to undergo ultrafiltration. Hispanics were significantly less likely to undergo ultrafiltration compared to Caucasians or African Americans. After multivariate analysis, ultrafiltration was associated with significantly increased length of stay (Beta coefficient (BC) 1.7 days, p <0.001) and cost of hospitalization (BC $10,916, p <0.001). In-patient mortality was not different between those who underwent ultrafiltration versus those who did not (Odds ratio 1.054, p=0.55).
Conclusion: The use of ultrafiltration for hospitalized patients with congestive heart failure remains very low. Ultrafiltration is associated with significantly increased length and cost of hospitalization.
