Objectives: To describe the prescribing practices, preparation and administration techniques of intrapleural (IP) tissue plasminogen activator (t-PA) and IP DNase in patients at a tertiary academic medical center. Methods: Adult patients receiving IP t-PA and IP DNase between January 1-December 31, 2012 were retrospectively evaluated. Patients were included if they received IP t-PA and/or IP DNase for a pleural infection and were excluded if they received IP t-PA or IP DNase for chest tube clearance. Results: A total of 197 doses of IP t-PA and IP DNase received amongst 30 patients were included. The mean age of the patients included was 62 years old with 50% of the patients being female. Of the 30 patients included, 18 patients (60%) received both IP t-PA and IP DNase and 12 patients (40%) received only IP t-PA. The median dose of IP t-PA received was 4 mg (IQR 2-10) and the median dose of IP DNase received was 5 mg (IQR 5-5). Systemic antibiotics were administered to 77% of patients prior to IP t-PA or IP DNase administration. Improved pleural effusion drainage was reported in 70% of patients. Increased pain in the chest cavity during administration of IP t-PA or IP DNase was reported in 7% of patients. Conclusion: The majority of patients at our institution received concomitant IP t-PA and IP DNase after systemic therapy for treatment of pleural infections had been attempted. Administration of IP t-PA and IP DNase demonstrated improved drainage of pleural infections with minimal harm to patients.
