Abstract
- Objectives: Lung cancer screening (LCS) is effective in reducing lung cancer mortality, but there is limited information available regarding preferences among high-risk individuals concerning LCS. In this study, we use a conjoint valuation analysis (CVA) to better understand which LCS attributes most affect LCS preferences.<br />Materials and Methods: We implemented a web-based nationally representative survey that included a full-profile CVA exercise. Participants were over the age of 45, had at least a 20 pack-year smoking history, and no history of lung cancer. The CVA instrument included five LCS attributes, and additional survey items collected demographic and psychosocial information.<br />Results: Participants (n = 210) had a mean age of 61 (SD 8.5) years, approximately half were female (51.9%), and were racially/ethnically diverse. Average relative importance of the LCS program attributes was (from high to low): out of pocket costs (27.3 ± 17.7); provider recommendation (24.8 ± 13.4); mortality reduction (17.2 ± 8.9); false-positive rate (15.8 ± 10.4); and ease of access (14.8 ± 7.3). There was large variation among individuals, but few significant associations of propensity to screen with individual demographic characteristics. Average screening propensity across individuals (1-9 scale) was 3.63 ± 1.6, and average rates of individual scenarios ranged from 2.60 ± 2.00 to 5.57 ± 2.13, indicating low inclination for screening.<br />Conclusions: We found that overall propensity for screening is low in a high-risk population, and that out of pocket costs were of greater importance to potential screeners than mortality reduction or false-positive rates. Thus, individuals considering or eligible for LCS need additional education and support regarding the LCS landscape in order to achieve informed decision making.<br /> (© 2019 The Authors.
