Clinical inquiries. Does office spirometry improve quit rates in smokers?

Abstract

It depends. Simply performing spirometry and offering cessation advice doesn't improve quit rates in patients who smoke (strength of recommendation [SOR]: A, systematic review of randomized controlled trials [RCTs]). However, when the spirometry results are communicated in terms of "lung age", smokers are more likely to quit (SOR: B, large RCT). Patients with abnormal spirometry results may be more likely to quit than patients with normal results (SOR: B, cohort studies).
