Purpose: Management of complicated pleural effusions and empyema using tube thoracostomy with intrapleural fibrinolysis versus surgical drainage has been debated for decades. However, there remains considerable variation in management with these approaches in the pediatric population. This study aims to compare the nationwide outcomes of pediatric patients with complicated pleural effusions.
Methods: Patients <18 years old with a diagnosis of pleural effusion or empyema associated with pneumonia were identified from the Nationwide Readmissions Database (2016-2018). Demographics, hospital characteristics, and complications were compared among patients undergoing isolated percutaneous drainage (PD), percutaneous drainage with intrapleural fibrinolysis (PDF), or operative drainage (OD) using standard statistical tests.
Results: 5424 patients (age 4 [IQR 1-11] years) were identified with a pleural effusion or empyema who underwent percutaneous or surgical intervention. PD (22%) and OD (24%) were utilized more frequently than PDF (3%). Index complications, including bleeding and postprocedural air leak, were similar between groups. Those receiving PDF had lower index length of stay (LOS) and admission costs. Thirty-day and overall readmission rates were highest in patients receiving PD (15% and 24%) and OD (12% and 23%) versus PDF, all p < 0.001. Those receiving OD had fewer readmission complications including recurrent effusion or empyema, pneumonia, and bleeding. Overall readmission cost was highest in those receiving PD (p = 0.005).
Conclusion: In this nationwide cohort, PDF was associated with lower index admission cost, shorter LOS and lower rates of readmissions compared to OD. This knowledge should be used to improve selection of these treatments in this patient population.
