Increasing Lung Cancer Screening Uptake Among Emergency Department Patients - LCS R01

This randomized clinical trial will evaluate strategies to improve lung cancer screening uptake among emergency department patients who meet lung cancer screening eligibility criteria based on age and smoking history. Participants will be randomized using a 2 by 2 factorial design into one of four groups: basic referral, basic referral plus text messaging, facilitated referral, or facilitated referral plus text messaging.

The basic referral strategy includes verbal referral to the lung cancer screening program and primary care provider, if applicable, along with written contact information for the lung cancer screening program navigator. The facilitated referral strategy includes submission of a lung cancer screening requisition to the lung cancer screening program on behalf of the participant during the emergency department visit.

The text messaging intervention includes a series of theory informed messages designed to increase intention and motivation to complete lung cancer screening. Lung cancer screening uptake will be assessed at 120 days after enrollment using participant follow up and electronic health record review.
