Refining interpretation of national trends in lung cancer screening discussions

This letter comments on Williamson et al.'s nationally representative analysis of patient-clinician discussions on LCS across the 2013-2021 USPSTF guideline periods. We highlight that changes in survey wording and approximated eligibility criteria may partially explain the reported decline in discussions, rather than a true reduction in clinician engagement. We emphasize the behavioral and measurement implications of terminology awareness and eligibility approximation, and propose analytic considerations for future surveillance efforts to support equitable translation of LCS guidelines.
