This randomized clinical trial evaluates the effectiveness of text messaging and facilitated referral strategies to increase lung cancer screening uptake among emergency department patients who meet lung cancer screening eligibility criteria.
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.

Participants are verbally referred to the lung cancer screening program and their primary care provider if applicable. Written materials with contact information for the lung cancer screening program navigator are provided.
A lung cancer screening requisition form is submitted to the lung cancer screening program on behalf of the participant during the emergency department visit. The screening program will contact the participant to discuss screening and schedule a low dose CT scan if appropriate.
Participants receive a series of up to 9 theory informed text messages designed to increase awareness, motivation, and completion of lung cancer screening.
Proportion of Participants Who Complete Lung Cancer Screening Within 120 Days After Enrollment
Lung cancer screening uptake is defined as completion of a low dose computed tomography scan for lung cancer screening within 120 days after enrollment. Screening completion will be confirmed using electronic health record review, lung cancer screening program records, or participant self report obtained during follow up. The outcome is reported as the proportion of participants who complete screening.
Time frame: Up to 120 Days After Enrollment
Proportion of Participants Who Participate in Shared Decision Making for Lung Cancer Screening Within 120 Days After Enrollment
Participation in shared decision making is defined as documentation of a shared decision making discussion regarding lung cancer screening or participant self report of completing such a discussion within 120 days after enrollment. The outcome is reported as the proportion of participants who participate in shared decision making.
Time frame: Up to 120 Days After Enrollment
Frequency of Reported Barriers to Lung Cancer Screening at 120 Days
Barriers to lung cancer screening are assessed using participant responses to a structured questionnaire administered at follow up. The questionnaire includes items on transportation challenges, cost concerns, scheduling difficulties, and fear of screening results. The outcome is reported as the number and proportion of participants reporting each barrier.
Time frame: 120 Days After Enrollment
Acceptability of Emergency Department Based Lung Cancer Screening Interventions at 120 Days
Acceptability is assessed using participant responses to Likert scale questionnaire items evaluating the degree to which participants find the emergency department based lung cancer screening interventions acceptable. Each item is scored on a 5 point Likert scale ranging from 1 to 5, with higher scores indicating greater acceptability. The outcome is reported as summary scores based on participant responses.

Appropriateness of Emergency Department Based Lung Cancer Screening Interventions at 120 Days
Appropriateness is assessed using participant responses to Likert scale questionnaire items evaluating the perceived fit and relevance of emergency department based lung cancer screening interventions. Each item is scored on a 5 point Likert scale ranging from 1 to 5, with higher scores indicating greater perceived appropriateness. The outcome is reported as summary scores based on participant responses.
Time frame: 120 Days After Enrollment
Frequency of Reported Facilitators to Lung Cancer Screening at 120 Days
Facilitators to lung cancer screening are assessed using participant responses to a structured questionnaire administered at follow up. The questionnaire includes items related to factors such as access to care, health literacy, prior healthcare engagement, and presence of a primary care provider. The outcome is reported as the number and proportion of participants reporting each facilitator.
