Abstract 19695: Burden of Acute Pericarditis on the Hospitals in USA: Analysis of Nationwide Emergency Department Sample Data
Introduction: Despite a high frequency of pericardial diseases, epidemiological studies related to pericarditis are limited. This study was done to analyze the trend of burden imposed by acute pericarditis on Emergency Departments in USA and identify factors associated with high rate of hospitalizations.
Methods: We used Nationwide Emergency Department (ED) Sample data to extract data for patients who visited ED with first listed diagnosis of acute pericarditis using International Classification Disease 9 code of 420. Data was extracted for the years 2006 to 2013. Admission rate to hospitals from ED visits was calculated. Sub-analysis was done to determine demographic parameters, hospital status and geographical regions associated with high admission rate.
Results: We identified a total of 120,260 ED visits with first listed diagnosis of acute pericarditis for the years 2006-2013 with average admission rate of 71.97%. The rate of ED visits remained largely unchanged from 4.9 visits per 100,000 persons in 2006 to 5.0 visits per 100,000 persons in 2013. The admission rate of patients visiting ED with first listed diagnosis of acute pericarditis declined significantly from 77.99% to 66.12% for the time period 2006-13 (p value=0.0002). The expected percentage of ED discharge increased by 1.82 times each year (CI = 1.28-2.36)
Sub-analysis revealed that patients with older age, female gender and Medicare insurance were associated with higher admission rates from ED visits (p<0.01). Also, hospitals in North-east region of USA, metropolitan areas and teaching hospitals were associated with high admission rates for patients with acute pericarditis (p<0.01).
Conclusions: This study reveals largely unchanged burden of acute pericarditis on US emergency rooms over last decade, with significantly decreasing rate of hospitalizations for years from 2006-2013. Also, there are huge demographic and geographic variations in admission rates indicating the unmet need for potential interventions to decrease hospitalization rates.
