Does office spirometry improve quit rates in smokers?
Metadata[+] Show full item record
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).
