Introduction: Diastolic heart failure is a major cause of morbidity, mortality and financial burden in the United States. However, recent nationwide trends in healthcare resource utilization and in-hospital outcomes are sparse.
Methods: National Inpatient Sample database 2007-2012, from Healthcare Utilization Project was used for the analyses. ICD-9CM principal diagnosis codes (428.30-428.33) were utilized to retrieve hospitalizations for diastolic heart failure. We analyzed utilization of healthcare resources, length of stay, and in-hospital mortality and their recent trends.
Results: There were a total of 1,157,125 hospitalizations primarily for diastolic heart failure for patients aged ≥18 years, from 2007-2012. Mean age was 76 years. Nearly 65% were females. About 73% were Whites and 16.4% were African Americans. Hospitalization rate was 29.6 per 100,000 adults in 2007; 68.7 per 100,000 persons in 2008; 84.4 per 100,000 persons in 2009; 95.5 per 100,000 persons in 2010; 106.5 per 100,000 in 2011; 107.3 per 100,000 persons in 2012. There was no significant change in in-hospital mortality rate (2.6% in 2007 to 2.4% in 2012; P-trend 0.55). Mean length of stay decreased from 5.47 days in 2007 to 5.23 days in 2012 (P-trend <0.001). Discharge to extended care facilities increased from 22.4% in 2007 to 24.8% in 2012 (P-trend <0.001). Utilization home-healthcare increased from 20.8% in 2007 to 25.6% in 2012(P-trend <0.001). However, discharge to home without home-healthcare decreased significantly from 52% in 2007 to 44.7% in 2012 (p-trend <0.001). Mean hospitalization costs were $10,783 per admission in 2007 and $10,076 in 2012. Inhospital mortality was 1%, 1.2%, 2%, and 3.5% for age groups <40 years, 40-64 years, 65-79 years and ≥80 years (Adjusted OR: 3.85; 95%CI: 2.45-6.07; p<0.001). Overall, diastolic heart failure as a principal diagnosis amounted for 6,190,619 inpatient days in the United States from 2007 to 2012.
Conclusions: There was a steady increase in diastolic heart failure related hospitalizations from 2007 to 2012. Cumulatively, patients with diastolic heart failure spent over 1 million inpatient-days every year in the United States.
