BackgroundAcute pericarditis accounts for a considerable number of emergency room visits and subsequent hospitalization. The rate and cost readmission due to AP is yet to be determined. Therefore, we sought to study the causes and predictors of 30-day readmissions after index admission with AP.MethodUsing the National Readmission database (NRD) 2016, we identified AP patients using ICD-10 codes. We evaluated the causes and predictors of 30-day readmission using multivariable logistic regression.ResultsA total of 13,844 patients (mean age 55.2 years, 40% women) were diagnosed with acute pericarditis as index admission. The most common comorbidities were hypertension (39.8%), followed by dyslipidemia (38.0%), fluid and electrolytes disorders (29.1%), and coronary artery disease (27.7%). The median length of stay for the cohort was 3 days (IQR, 2 - 7 days). The 30-day readmission rate post-acute pericarditis was 17.8%. The risk of all-cause 30-day readmission was higher in in women (OR 1.33; 95% CI 1.21-1.47), patients aged 40 - 64 years (OR 1.22; 95% CI 1.06-1.40), patients with anemia, heart failure, chronic pulmonary disease, diabetes mellitus, and drug abuse (P - 0.042 for all). The median cost of 30-day readmissions was $9,932 (IQR, $5,517 - $18,876).ConclusionThe rate of readmission after AP is high and associated with higher comorbidities and cost.
