Abstract 17286: National Trends in Hospital Readmission Rates in Congestive Heart Failure Patients
Background: Congestive heart failure (CHF) is the leading cause of hospitalization among adults in the United States. Despite improvement in outcomes with medical therapy, readmission rates following CHF hospitalization remain high at ≥50% within 6 months of discharge. The Affordable Care Act, passed in 2010, imposes a financial penalty on hospitals with high 30-day readmission rates. We aimed to look at the national trends in 30-day readmission rates after CHF hospitalization.
Methods: We used Nationwide Readmissions Database (NRD) data from 2009 through 2013 to identify CHF-related readmissions using Clinical Classifications Software code 108 (includes ICD-9 codes 428, 398.91) as the principal discharge diagnosis.
Results: Overall, the national 30-day readmission rate after CHF-related hospitalization was 24%. From 2009 to 2013, there was a 1.6% reduction in 30-day readmissions for CHF related hospitalization [214,198 in 2009 (25.1%) vs. 183,534 in 2013 (23.5%)] (Figure 1A). The majority of the re-admissions were for CHF followed by renal failure and sepsis. The readmissions for CHF as the primary discharge diagnosis also decreased from 2009 to 2013 [81,780 (9.6%) vs. 65,458 (8.4%)]. The readmissions were highest in the age group 18-44 years followed by 45-65 years and then >65 years. There was slight male predominance (53%) for CHF-related readmissions. The cost of CHF-related readmissions was substantially higher than index hospitalizations and continued to increase from 2009 to 2013 (Figure 1B). Medicaid was the largest payer of readmissions followed by medicare, the uninsured, and private insurance.
Conclusions: While there is a mild reduction in the 30-day readmission rates after CHF related hospitalizations from 2009-2013, the cost of readmissions continues to rise. Strategies to further reduce CHF-related readmissions are needed to reduce the overall cost and morbidity associated with disease.
