Management of Malignant Pleural Effusions in U.S. Veterans: A Retrospective Review.

Purpose: To compare malignant pleural effusion (MPE) treatment outcomes and complications among patients receiving indwelling pleural catheter (IPC), talc pleurodesis (TPS), or dual therapy. Outcomes were determined by measuring length of stay (LOS) and post-procedure dyspnea scores. Complications were measured by comparing intervention failures and adverse events.

Methods: The Veterans Affairs' Corporate Data Warehouse was utilized to retrospectively review the charts of 314 MPE subjects. Dyspnea scores were estimated by researchers and LOS was determined by adding the duration of stay for all admissions post procedure. Complications were recorded through chart review.

Results: IPC exhibited higher failure rates than the other approaches 1 year post intervention. Pneumonia/chest infection rate and lung entrapment were also more prevalent. There was no significant difference in dyspnea rates. LOS illustrated a significant difference between groups, with talc patients spending a median of 7 days in the hospital immediately post procedure, while IPC and IPC + TPS patients spent a median of 3 and 2 days, respectively.

Conclusion: Patients receiving IPC or combination treatment spend fewer days in the hospital than TPS patients. However, IPC appears to be associated with more adverse events and higher long-term failure rates than other management strategies.
