Combined intrapleural therapy with tissue plasminogen activator (tPA) and deoxyribonuclease (DNase) has been shown to reduce the need for surgical intervention for complicated pleural effusion/empyema (CPE/empyema). For patients in whom tPA/DNase is likely to fail, however, receipt of this therapy may simply delay the inevitable. The goal of this study was to identify risk factors for failure of combined intrapleural therapy. ⋯ Our analysis found that the presence of pleural thickening and the presence of an abscess/necrotizing pneumonia helps to triage patients in whom combined intrapleural therapy is likely to fail. The results warrant further study and validation in a prospective multicenter study.
