Stakeholder engagement to initiate lung cancer screening in an urban safety-net health system.

• Health systems, especially those caring for medically underserved populations, should consider a multi-level approach to patient and stakeholder engagement to advance adoption of population screening as guideline-based care. • Iterative engagement should inform design and activation of an electronic order set to (1) capture socio-demographic data to establish screening eligibility, and (2) provide CMS-mandated documentation of patient counseling, while minimizing order burden for referring clinicians. • Patients who most stand to benefit from guideline-based lung cancer screening may also be those least likely to complete the multi-step processes of screening.
