Abstract A148: Perceptions of lung cancer screening among Native American patients: The Tribally Engaged Approaches to Lung Screening (TEALS) study

Abstract Introduction: Uptake of lung cancer screening (LCS) with low dose computed tomography is poor nationwide. The U.S. Native American (NA) population has a high prevalence of smoking and lung cancer mortality but low rates of LCS completion. Awareness and perceptions of LCS among NA men and women have rarely been studied. Methods: Using a community-engaged research approach in partnership with the Choctaw Nation Health Services Authority in Oklahoma, the “Tribally Engaged Approaches to Lung Screening” study developed and implemented a cluster-randomized controlled trial of a coordinated LCS program. In 2022, NA men and women eligible for LCS from six tribal health clinics completed a baseline survey prior to being referred for LCS. Surveys included demographic characteristics, smoking history, use of cancer preventive services, beliefs regarding personal risk of lung cancer, and perceptions toward LCS. Findings: Among 210 participants (57% women, 43% men), mean age was 63 years; 50% reported annual household income below $25,000, 83% completed high school or equivalent, with 40% having some college education. The median pack years of smoking was 46 years. The proportion of participants who currently smoke was 72%. Current cigarette users were slightly younger than former users (median age 61 vs 64 years, respectively) and similarly had lower maximum estimates of pack-years of use (median, 44 vs 52). Most (93%) had more than one primary care visit within the past 12 months, and 76% completed an annual physical or wellness visit in the past year. Overall, 73% had completed colonoscopy and, among women, 80% had a mammogram. Only 62% had heard about LCS. However, 74% agreed with the statement “It is likely that I will get lung cancer sometime in my lifetime”. More than 90% of participants agreed that LCS would help with each of the following: early detection, chances of dying from lung cancer, reduce personal worry about lung cancer, reduce their family’s worries, improve planning for the future and peace of mind. However, 44% worried that LCS would find “something wrong”, 15% endorsed that they would rather not know if they had any lung problems, and 10% were afraid the scan would damage their lungs. About 20% worried about being a social outcast or being blamed for having smoked. Regarding potential barriers, 32% felt that cost would be a problem, 28% felt they did not have the time, and 17% that transportation would be a problem. Overall,14% reported bad experiences with healthcare or a provider, and 8% did not trust the healthcare system. Regarding LCS, 28% felt they did not know enough about the test, 11% felt they were too old to benefit from LCS, and 8% felt LCS was not worth the effort. Conclusions: Perceptions of the potential benefits from LCS were overall favorable in this sample of NA adults. However, up to 30% perceived significant barriers to LCS uptake. Greater awareness of LCS and mitigation of barriers to LCS would help to reduce the marked disparities in lung cancer mortality among NA patients. Citation Format: Dorothy A.
