Bronchoscopy with bronchoalveolar lavage: determinants of yield and impact on management in immunosuppressed patients
2011
Fibreoptic bronchoscopy with bronchoalveolar lavage (FOB/BAL) is a common modality for the evaluation of pulmonary infiltrates.1 2 We recognised there are limitations of comparison between subgroups of immunosuppressed patients, non-uniform definitions of a positive yield, suboptimal description of the impact of concurrent antimicrobial use at the time of the bronchoscopy and sometimes insufficient assessment of management decisions surrounding FOB/BAL.3–5 To address these issues, we performed a retrospective analysis of 190 immunosuppressed patients who underwent FOB/BAL for a pulmonary abnormality (clinical or radiographic) at the University of Rochester Medical Center from 2005 to 2008. A positive yield was defined as one of the following: (1) positive culture—bacterial, viral or fungal (not including Candida albicans alone); (2) positive finding on cytopathology or fungal stain; or (3) diffuse alveolar haemorrhage.
