Background: This study sought to examine recent trends of 30-day outcomes including in-hospital mortality, readmission and a prolonged length of stay (LOS) among patients hospitalized for acute heart failure (HF).
Methods: We identified patients hospitalized for HF between 2008 and 2014 in a large US administrative claims database (Truven Health Marketscan® Database). Thirty-day outcomes were identified and categorized hierarchically in this order: in-hospital deaths, all-cause readmission, and a LOS>10 days. We conducted trend analysis examining annual changes in the incidence proportion over the study period.
Results: A total of 131,421 patients with the first acute HF hospitalization were identified over the study period. The mean age was 74.4 (SD=13.6) and 53.7% were male. Overall, 16.5% of patients experienced one of the 3 outcomes within 30 days. We detected no statistically significant changes over the 7-year period for the outcomes (see Figure 1). Over time, we observed a slight increasing prevalence of comorbid conditions including atrial fibrillation and chronic kidney disease. Additionally, there were changes in the use of therapies including a decreasing use of angiotensin-converting enzyme (ACE) inhibitors and inotropic agents.
Conclusions: Among patients hospitalized for acute heart failure, the 30-day outcomes remained steady over a 7-year period despite temporal changes in some comorbid conditions and medication use.
