Background: Primary cardiac tumors (PCT) are rare with an incidence of 0.3-0.7%. We aimed to study the rate, causes and independent predictors for 30-day readmissions in patients diagnosed with PCT using a national level database.
Methods: We conducted a retrospective cohort analysis using the National Readmissions Database between 2016-2018. ICD-10 codes were used to identify patients with benign and malignant PCT. Patients <18 years and December admissions were excluded. Primary outcomes were the readmission rate and principal diagnosis for 30-day readmissions in patients hospitalized with primary diagnosis of PCT. Multivariate logistic regression was used for analysis.
Results: 4451 patients were admitted with the primary diagnosis of PCT, out of which 4348 patients were discharged alive. Among those discharged alive, 13.8% (599 patients) were readmitted within 30 days. The most common principal diagnosis for 30-day readmissions were subsequent admission for benign PCT (17.12%), atrial fibrillation (8.1%), sepsis (5.3%), pneumonia (4.04%), hypertensive heart disease with heart failure (2.6%), supraventricular tachycardia (2.54%), non-inflammatory pericardial effusion (2.31%), and pleural effusion (2.22). For the index admissions, 65.7% were females, and mean age was 60.8 years. The in-hospital mortality rate for index admissions was 2.28% while it was 2.36% for the readmission. For the index admission, mean length of stay was 8 days while mean total charges were $163,636. For all the readmissions combined, the total length of stay was 3598 days and combined total charges were $54.7 million. The independent predictors for readmission were atrial fibrillation (OR 0.71, p=0.02), myocardial infarction (OR 2.89, p=0.006), acute liver failure/hepatic cirrhosis (OR 2.34, p=0.02), and diabetes mellitus (OR 1.75, p=0.002).
Conclusion: In patients with a principal diagnosis of PCT, the 30-day readmission rate is 13.8% and the most common principal diagnosis for readmissions are PCT complications, atrial fibrillation, supraventricular tachycardia, pneumonia, sepsis, hypertensive heart disease with heart failure, pericardial effusion, and pleural effusion.
