[Risk and Mortality Factors for Pleural Effusions Requiring Diagnostic Thoracentesis].

Introduction: Occurrence of malignant pleural effusion (PE) is known to be associated with a poor prognosis, but the mortality of patients with non-malignant effusions has not been sufficiently studied. Our objective was to describe the clinical course and explore risk factors associated with all-cause mortality at 1, 5 and 10 years in patients who develop a PE.

Methods: Retrospective observational study of patients undergoing diagnostic thoracentesis during the decade 2008-2017 in a pulmonology service.
