Abstract
Surgical volume outcome relationships are well established but have not been studied in patients with interstitial lung disease (ILD) undergoing surgical lung biopsy. Our study objective was to determine if hospital surgical lung biopsy volume is associated with post-operative mortality in patients with ILD.
A cohort study using administrative, population-based data from Ontario, Canada was performed in adults with ILD who underwent a surgical lung biopsy between 2001 and 2014. The association between yearly hospital surgical lung biopsy volume and 30-day post-operative mortality was assessed using multilevel logistic regression modeling.
3057 surgical lung biopsies for ILD were performed during the study period with a median yearly hospital volume of 73 (IQR 34,143) procedures. 30-day mortality was 7.1%, 20.2% and 1.9% in overall, non-elective and elective patients, respectively. Higher yearly hospital surgical lung biopsy volume was associated with lower odds of 30-day post-operative mortality after adjusting for patient characteristics [OR 0.84 95% CI (0.73, 0.97), p=0.02)], with the association appearing stronger for non-elective procedures [OR 0.84 95% CI (0.69, 1.02), p=0.08) versus OR 0.94 95% CI (0.74, 1.18), p=0.57) in elective procedures].
Higher yearly hospital surgical lung biopsy volume was associated with lower post-operative mortality in patients with ILD with the association appearing to be mainly driven by non-elective cases. Surgical lung biopsy mortality was significantly higher for non-elective cases.
