Abstract B036: Feasibility, acceptability, and preliminary impact of a text messaging intervention to increase the uptake of lung cancer screening among Latinos

Abstract Purpose: Assess the feasibility, acceptability, and preliminary impact of A todo pulmón, a text messaging intervention to increase the uptake of lung cancer screening among Latinos. Methods: This was a single-arm pilot study with 40 Latinos who were eligible for lung cancer screening but have not completed their annual screening. Participants were recruited using clinic- and community-based efforts. All participants received A todo pulmón. Informed by the Health Belief and Cultural Accommodation models, A todo pulmón is a 12-week, culturally accommodated text messaging intervention (available in English and Spanish) to increase uptake of lung cancer screening among Latinos. Results: At baseline, participants had a mean age of 59.1 years (SD = 6.5); 50% were women, 57.5% preferred Spanish, and 52.5% had a high school education or less. Nearly half were from Puerto Rico (47.5%) and 40% were born in the continental U.S. Most participants (95%) reported having health insurance and 60% experienced food insecurity. More than half of participants (55%) were currently smoking, 65% had never heard of lung cancer screening, and 72.5% were unaware of their eligibility for lung cancer screening. Thirty-five participants (87.5%) completed the follow-up assessment at Week 12. The self-reported lung cancer screening rate was 20% (8/40). The electronic health record-verified lung cancer screening rate was 25% (10/40). Thirteen participants (32.5%; 13/40) completed the shared decision-making process. Thirty participants (90.9%, 30/33) reported being satisfied or extremely satisfied with A todo pulmón, and all participants (100%, 33/33) indicated they would recommend it to a friend or family member. Conclusion: It is feasible to recruit and retain Latinos in a lung cancer screening study. A todo pulmón is acceptable and holds promising preliminary impact among Latinos. Additional testing in a formal randomized clinical trial is warranted to assess the efficacy of the intervention. Citation Format: Jeffrey W. Ramos Santiago, Rafael H.
