The study will develop and test the feasibility of the Lung Cancer Assessment of Risk and Education (LungCARE) intervention to increase discussions about lung cancer screening between patients and physicians. This intervention will be designed to reach primary care patients and will be implemented at three levels of the healthcare structure: patient, physician, and system. The patient component includes a short lung cancer screening video and questions regarding screening preferences. Patients will receive immediate feedback in a report (patient report) that summarizes their lung cancer screening preferences and a handout summarizing the educational video. At the physician level, primary care physicians (PCPs) will receive a similar report (physician report), which will be delivered to them prior to the patient visit. The report contains additional information about documenting discussion related to risk, screening, and referrals in the electronic health record (EHR) system (system component). The investigators will develop the LungCARE intervention and have a comparison group that will receive usual care. Preliminary testing of LungCARE will occur via a randomized controlled trial (RCT) at the University of California, San Francisco, General Internal Medicine and Women's Health Primary Care clinics. The RCT will evaluate LungCARE among 50 PCPs and 120 high-risk current and former smoker patients. The investigators will determine whether the intervention is accepted by patients and physicians and whether patients who received LungCARE are more likely to discuss lung cancer screening with their physicians when compared to patients and physicians in the comparison group. The investigators will also determine whether the intervention affects knowledge of lung cancer and low-dose computed tomography (LDCT) screening, perception of risk, and worry about lung cancer in patients when compared to patients in the comparison group. The investigators expect their research to provide specific recommendations that will facilitate patient-physician discussions about LDCT screening and promote shared decision-making among patients and physicians.
