Standardized bleeding definitions after transbronchial lung biopsy: a Delphi consensus statement from the Nashville Working Group.

Thirty-six expert bronchoscopists from eight countries, both in academic and community practice settings, participated in creation of the scale. After the live meeting, two iterations were made. The second and final scale was vetted by all 36 participants, with a weighted average of 4.47/5; 53% were satisfied, and 47% were very satisfied. The panel reached a consensus and propose the Nashville Bleeding Scale.
