Centralized Lung Cancer EARly Detection Among Smokers (CLEAR Study)

Improving the Quality of Smoking Cessation and Shared Decision Making for Lung Cancer Screening: A Cluster Randomized Trial

Source: ClinicalTrials.gov · Last updated 22 Aug 2025

Brief summary (registry, in English)

This trial studies how well a centralized care strategy works in improving the quality of smoking cessation and shared decision making among patients who smoke and are considering lung cancer screening. The centralized care strategy is a model where smokers eligible for lung cancer screening are referred to a dedicated tobacco treatment program where they receive both the shared decision-making and initiate smoking cessation counseling prior to their visit with a primary care provider. Utilizing the centralized care model may work better in helping people quit smoking and make informed decisions about lung cancer screening compared to usual care.
