Abstract 15819: Trend of Heart Failure Hospitalizations in USA: 10 Year Analysis of Nationwide Inpatient Sample Data
Background: Congestive heart failure (CHF) is a major cause of morbidity and mortality in USA with a huge economic burden on health care. This study was done to determine the trend of hospitalizations from CHF, length of stay, mean cost of hospitalization and discharge disposition over last decade (2002-2011).
Methods: We used Nationwide Inpatient Sample data to extract data for patients hospitalized with primary diagnosis of CHF using clinical classification software code of 108, corresponding to ICD 9 codes of 398.91, 428.0, 428.1, 428.20, 428.21, 428.22, 428.23, 428.30, 428.31, 428.32, 428.33, 428.40, 428.41, 428.42, 428.43, 428.9. NIS is a nationally representative survey of hospitalizations conducted by the Healthcare Cost and Utilization Project developed through a Federal-State-Industry partnership and sponsored by Agency for Healthcare Research and Quality. It represents 20% of all hospital data in US. Data was extracted for the years 2001-2011. Trend of rate of hospitalizations, mean length of stay, mean cost of hospitalization, in-hospital mortality and discharge disposition were analyzed.
Results: Total hospitalizations for CHF as primary diagnosis declined from 368.4 per 100,000 persons in 2001 to 311.4 per 100,000 persons in 2011. Mean length of stay of these hospitalizations decreased from 5.6 days in 2001 to 5.1 days in 2011. Mean cost of hospitalization increased from $16,925 in 2001 to $38,561 in 2011. Routine discharges decreased from 60.79% to 49.93%, whereas discharge to skilled nursing facility and home health care increased from 17.05% to 20.82% and 13.05% to 21.84% respectively. In hospital mortality decreased by 31.6% over last decade, decreasing from 4.59% in 2001 to 3.14% in 2011.
Conclusions: Our study shows that over last decade hospitalizations from CHF, mean length of stay and in-hospital mortality has decreased significantly pointing towards improving care for CHF patients. However, increasing mean cost of hospitalizations and increasing discharge rate to skilled nursing facilities and home health care indicates increasing economic burden of CHF on health care.
