MedicalResearch: What are the main findings of the study?
We analyzed data from almost 4 million hospitalizations for atrial fibrillation (AF) from more than 1,200 hospitals across 45 states in last decade, and found that
- Hospitalization rates for atrial fibrillation have increased exponentially among US adults during the past 10 years, particularly in those 65 years or older.
- The most frequent coexisting conditions were hypertension (59.99%), diabetes (21.47%) and chronic pulmonary disease (20.01%).
- In terms of geographic distribution of admissions, the hospitals in the South constitute (38.5%) the highest percentage of atrial fibrillation hospitalizations, followed by Midwest (24.9%), Northeast (22.2%) and West (14.4%).
- Overall in-hospital mortality was 1%. The mortality rate was highest in >80 years age group (1.93%) and patients with concomitant heart failure (8.2%).
- The percentage of patients discharged to nursing facility increased from 8.1% in 2000 to 11.5% in 2010 and need for home health care increased from 6.7% to 13.1%. Approximately one fourth of the patients (25.83%) were discharged to long-term care institution if atrial fibrillation
hospitalization was complicated by acute ischemic stroke.
- Mean cost of AF hospitalization increased significantly from $6,410 in 2001 to $8,439 in 2010 (24.04% increase, p <0.001) even after adjusting for inflation. This represents an absolute increment in annual national cost from approximate 2.15 billion dollars in 2001 to 3.46 billion dollars in 2010. The mean cost of care was highest if AF hospitalization was associated with heart failure ($33,161) and valvular disorders ($28,030).
