Factors associated with lung cancer risk factor documentation.

Objectives: To identify factors associated with the minimum necessary information to determine an individual’s eligibility for lung cancer screening (ie, sufficient risk factor documentation) and to characterize clinic-level variability in documentation.

Study Design: Cross-sectional observational study using electronic health record data from an academic health system in 2019.

Methods: We calculated the relative risk of sufficient lung cancer risk factor documentation by patient-, provider-, and system-level variables using Poisson regression models, clustering by clinic.
