Researchers from the Medical University of South Carolina in Charleston distributed the survey to 401 practicing pulmonologists who are members of the American College of Chest Physicians.
Only 22% of respondents said pulmonologists bore the leading responsibility for ordering biomarker testing, though 83% said pulmonologists were responsible for ordering an initial diagnostic biopsy.
Characteristics associated with pulmonologists who said they order biomarker testing were longer practice tenure, higher case volumes and participation in a multidisciplinary tumor board, according to the study.
