Lung cancer screening status and acceptability of a personalized approach in Texas.

Abstract

e22516 Background: Current lung cancer screening (LCS) guidelines rely on age and smoking history. Despite its proven benefit, only 5-15% of eligible patients receive LCS, with Texas having one of the lowest rates among states in the US. Personalized screening strategies select people for LCS based on their personal lung cancer risk and may increase LCS’s effectiveness and efficiency. We assess current LCS practices and the acceptability of personalized LCS among primary care providers (PCP) in Texas. Methods: We surveyed 32,983 Texas-based PCPs including primary care physicians, physician assistants, and nurse practitioners on an existing network (Protocol 2019-1257; PI: Dr. Shete), and 400 attendees of the 2022 Texas Academy of Family Physicians (TAFP) conference. Deidentified demographics, current LCS practices, and acceptability of personalized LCS were obtained. We analyzed the responses by subgroups of interest using comparative statistics. Using nonparametric bootstrap, we derived an enriched dataset and utilized it to develop logistic regression models to further understand respondent tendencies related to current LCS practices and acceptability of personalized LCS. Results: Response rates were 0.3% (n=91) and 15% (n=60) for the 2019-1257 and TAFP surveys, respectively. Respondent demographics are provided in the table. Most (84%) respondents regularly assess LCS in their practice, with those in the following categories more likely to assess for LCS eligibility: 40-49 years old, female, non-Black, physicians, with <10 years in practice, seeing >50 patients per week, and work at a non-residency training site (all p-values < 0.05). Half of the respondents were interested in adopting personalized LCS while an additional 40% wanted to learn more information. Respondents in the following categories were associated with increased interest in personalized LCS: younger than 60 years, non-White, non-physicians, seeing 100 or more patients per week, at a non-residency training site, and at a decentralized practice (all p values < 0.05). Majority (66%) of respondents expressed concerns regarding time availability with the personalized LCS. Conclusions: There is a great need to enhance the awareness and engagement of Texas-based PCPs about LCS. Most of the respondents expressed interest in personalized LCS. Time availability was the main concern related to personalized LCS. Findings from this project highlight the need for better education of Texas-based PCPs on the benefits of LCS, and the development of efficient decision tools to facilitate shared decision-making sessions to ensure successful implementation of personalized LCS.
