Abstract
BackgroundWhile chest tube placement with pleural fibrinolytic medication is the established treatment of pediatric empyema, treatment failure is reported in up to 20% of these children.ObjectiveStandardizing fibrinolytic administration among interventional radiology (IR) physicians to improve patient outcomes in pediatric parapneumonic effusion.Materials and methodsWe introduced a hospital-wide clinical pathway for parapneumonic effusion (1–2 mg tissue plasminogen activator [tPA] twice daily based on pleural US grade); we then collected prospective data for IR treatment May 2017 through February 2020. These data included demographics, co-morbidities, pediatric intensive care unit (PICU) admission, pleural US grade, culture results, daily tPA dose average, twice-daily dose days, skipped dose days, pleural therapy days, need for chest CT/a second IR procedure/surgical drainage, and length of stay. We compared the prospective data to historical controls with IR treatment from January 2013 to April 2017.ResultsSixty-three children and young adults were treated after clinical pathway implementation. IR referrals increased (P = 0.02) and included higher co-morbidities (P = 0.005) and more PICU patients (P = 0.05). Mean doses per day increased from 1.5 to 1.9 (P < 0.001), twice-daily dose days increased from 38% to 79% (P < 0.001) and median pleural therapy days decreased from 3.5 days to 2.5 days (P = 0.001). No IR patients needed surgical intervention. No statistical differences were observed for gender/age/weight, US grade, need for a second IR procedure or length of stay. US grade correlated with greater positive cultures, need for chest CT/second IR procedure, and pleural therapy days.ConclusionInterventional radiology physician standardization improved on a clinical pathway for fibrinolysis of parapneumonic effusion. Despite higher patient complexity, pleural therapy duration decreased. There were no chest tube failures needing surgical drainage.
