Aggregation of Asian American, Native Hawaiian, and Pacific Islander racial and ethnic groups may mask the true underlying disparities in screening uptake and diagnostic follow-up, creating barriers for targeted, preventive health care.<\/jats:p><\/jats:sec>Objective<\/jats:title>To examine racial and ethnic differences in LCS completion and follow-up rates in a multiethnic population.<\/jats:p><\/jats:sec>Design, Setting, and Participants<\/jats:title>This population-based cohort study was conducted at a health maintenance organization in Hawaii. LCS program participants were identified using electronic medical records from January 1, 2015, to December 31, 2019. Study eligibility requirements included being aged 55 to 79 years, a 30 pack-year smoking history, a current smoker or having quit within the past 15 years, at least 5 years past any lung cancer diagnosis and treatment, and cancer free. Data analysis was performed from June 2019 to October 2020.<\/jats:p><\/jats:sec>Exposure<\/jats:title>Eligible for LCS.<\/jats:p><\/jats:sec>Main Outcomes and Measures<\/jats:title>Screening rates were analyzed by self-reported race and ethnicity and completion of a low-dose computed tomography (LDCT) test. Diagnostic follow-up results were based on the Lung Imaging Reporting and Data System (Lung-RADS) staging system.<\/jats:p><\/jats:sec>Results<\/jats:title>A total of 1030 eligible LCS program members had an order placed; their mean (SD) age was 65.5 (5.8) years, and 633 (61%) were men. The largest racial and ethnic groups were non-Hispanic White (381 participants [37.0%]), Native Hawaiian or part Native Hawaiian (186 participants [18.1%]), and Japanese (146 participants [14.2%]). Men and Filipino, Chinese, Japanese, and non-Hispanic White individuals had a higher proportion of screen orders for LDCT compared with women and individuals of the other racial and ethnic groups. The overall LCS completion rate was 81% (838 participants). There was a 14% to 15% screening completion rate gap among groups. Asian individuals had the highest screening completion rate (266 participants [86%]) followed by Native Hawaiian (149 participants [80%]) and non-Hispanic White individuals (305 participants [80%]), Pacific Islander (50 participants [79%]) individuals, and individuals of other racial and ethnic groups (68 participants [77%]). Within Asian subgroups, Korean (31 participants [94%]) and Japanese (129 participants [88%]) individuals had the highest completion rates followed by Chinese individuals (28 participants [82%]) and Filipino individuals (78 participants [79%]). Of the 54 participants with Lung-RADS stage 3 disease, 93% (50 participants) completed a 6-month surveillance LDCT test; of 37 individuals with Lung-RADS stage 4 disease, 35 (97%) were followed-up for additional procedures.<\/jats:p><\/jats:sec>Conclusions and Relevance<\/jats:title>This cohort study found racial and ethnic disparities in LCS completion rates after disaggregation of Native Hawaiian, Pacific Islander, and Asian individuals and their subgroups. These findings suggest that future research is needed to understand factors that may be associated with LCS completion and follow-up behaviors among these racial and ethnic groups.<\/jats:p><\/jats:sec>","DOI":"10.1001\/jamanetworkopen.2021.44381","type":"journal-article","created":{"date-parts":[[2022,1,20]],"date-time":"2022-01-20T16:06:47Z","timestamp":1642694807000},"page":"e2144381","source":"Crossref","is-referenced-by-count":22,"title":["Lung Cancer Screening by Race and Ethnicity in an Integrated Health System in Hawaii"],"prefix":"10.1001","volume":"5","author":[{"given":"Caryn E.
