The use of pleuroscopy has expanded over the last decade due to its higher diagnostic yield and low complications rate. Whether the infectious complications of pleuroscopy performed in negative pressure rooms is similar to that of pleuroscopy performed in positive pressure rooms remain unclear. To assess the safety of pleuroscopy performed in negative pressure rooms, we sought to determine the rate of infectious complications in patients who underwent pleuroscopy in negative pressure bronchoscopy rooms at our institution. This was a retrospective cohort study of all patients who underwent pleuroscopy in our institution's negative pressure bronchoscopy rooms between January 2005 and January 2018. The primary outcome was the incidence of infectious complications at 14 and 30 days after the procedure. We identified 318 patients. Of the 318 patients, 47 (15%) had hematological malignancies, 118 (37%) had lung cancer, 121 (38%) had solid non-lung cancers, and 32 (10%) had no cancer diagnosis before the procedure. At the end of pleuroscopy, 255 patients (80%) had an indwelling pleural catheter placed, 63 patients (20%) had only a chest tube placed, and 31 patients (9%) had both an indwelling pleural catheter and chest tube placed. No patients developed empyema within 14 days. Three patients (0.9%) developed empyema within 30 days after the procedure and was presumed to be due to pleural catheter infection in all cases. Our findings show that pleuroscopy performed in negative pressure rooms has a low incidence of infectious complications, provided that proper sterile precautions are maintained.
