Larch: Multilevel Interventions to Increase Adherence to Lung Cancer Screening
Study Details
Study Description
Brief Summary
Screening for lung cancer has the potential for a profound public health benefit. Repeat annual screening is necessary for early detection of lung cancer. We will test two interventions which include patient education and reminders to improve adherence to lung cancer screening.

Detailed Description
Screening for lung cancer has the potential for a profound public health benefit.
Successful population-based screening requires continuous monitoring to adherence repeat screening in high risk adults to achieve similar results. Repeat annual screening is necessary for early detection of lung cancer. Baseline or first LDCT scans detect prevalent lung cancer, when subsequent screening detects new nodules. However, adherence to screening is low, ranging at 28-38% from centers nationally.
We developed two novel, patient-centered interventions to address patient education and offering reminders for on-time screening. To address our goals, our specific aims are to: 1) Compare effectiveness of two multilevel interventions relative to usual care in improving (a) rates of adherence to lung cancer screening, (b) patient-centered outcomes; and (c) clinic outcomes; and 2) Determine the patient-, clinician-, and system-level factors that influence changes in adherence to inform lung cancer screening programs.
Study Design
Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Patient Video only About 3 weeks after the index LDCT, the study Medical Assistant (MA) will deliver a link to the Patient Voices Video, an educational video about lung cancer screening. |
Other: Patient Education
The Patient Voices Video is an educational video about lung cancer screening.
|
Experimental: Stepped Reminders only Prior to patient's next LDCT scan is due, MA begins Stepped Reminders intervention: MA pends LDCT orders to PCP to sign. MA sends reminders to patient when order is placed and follows up by phone if patient has not scheduled LDCT. |
Other: Stepped Reminders
Stepped Reminders, which directly reminds providers to order the next LDCT scan and then reminds patients they are due and prompts them to schedule LDCT with Radiology.
|
Experimental: Patient Video and Stepped Reminders See above. Those assigned to the Patient Video and Stepped Reminders will receive both interventions, as described above. |
Other: Stepped Reminders
Stepped Reminders, which directly reminds providers to order the next LDCT scan and then reminds patients they are due and prompts them to schedule LDCT with Radiology.
Other: Patient Education
The Patient Voices Video is an educational video about lung cancer screening.
|
No Intervention: Usual Care Those assigned to the the Usual Care arm will continue to receive usual lung cancer screening care. |
Outcome Measures
Primary Outcome Measures
- Repeat annual lung cancer screening [9-15 months after index LDCT]
Electronic health records will be searched for screening low dose CT (LDCT).
Secondary Outcome Measures
- Knowledge of lung cancer screening [6-8 weeks after index LDCT]
Knowledge of lung cancer screening eligibility, time to return and cost on patient reported outcomes survey.
- Attitudes and beliefs [6-8 weeks after index LDCT]
The Lung Cancer Screening Health Beliefs metric.
