Participant adherence in a lung cancer screening (LCS) program in a non-smoking population.

Abstract

10556 Background: LCS guidelines in smoking populations includes an annual low-dose CT Chest (LDCT) scan. Historically, real-world adherence to repeat imaging following the baseline LDCT has been low at 22% (Silvestri et al. Chest 2023). Various reasons for non-adherence have been cited and can be amplified in populations where English is not the primary language, low health literacy, or logistical reasons that interfere with scheduling. We are conducting the Female Asian Nonsmoker Screening Study (FANSS), which is a pilot study for Asian women with no smoking history to provide LDCTs to this population. We describe the strategies utilized to address potential barriers to adherence and report the participant (pt) adherence observed to date for this population. Methods: FANSS is an IRB-approved trial that provides LDCTs annually for 3 years and has an interim follow-up phone call every 6 months. All aspects of the study other than the LDCT could be conducted virtually pending pt preference. All pt interactions were conducted in the pt’s requested language. LDCTs were interpreted according to Lung-RADS. Review of the LDCT results were available in-person or virtually by a nurse practitioner or the principal investigator. The timeline for the 2nd and 3rd LDCT after the baseline scan was determined as follows: pts with negative findings were recommended for a repeat LDCT in 1 year; pts with suspicious findings were reviewed at the NYU Multidisciplinary Nodule Board and recommended for a repeated LDCT in a 3 or 6 month interval. A bilingual (English and Chinese speaking) research coordinator and medical secretaries reached out to pts at their preferred contact (email, phone, or text) for scheduling the follow-up LDCT. Up to three attempts to reach pts to schedule their follow-up LDCT were made. Results: From 3/5/21 to 1/27/24, 634 subjects completed their baseline LDCTs. Language interpretation services were utilized in 30% of pts. As of 1/27/24, 215 pts were due for their 2nd LDCT: 195 (91%) completed (186) or scheduled (9) the LDCT, 5 pts withdrew their consent, and 15 did not complete the scan. The main reasons for not completing the scans were: living outside New York City, other health concerns, and lost to follow-up. As of 1/27/24, 95 pts were due for their 3rd LDCT: 87 (92%) completed (82) and scheduled (5) the LDCT, and 8 did not complete the scan due to being lost to follow-up. Conclusions: The FANSS population is a unique pt cohort comprised of all Asian women who do not qualify for current LCS guidelines. Interventions to address potential adherence issues were implemented. In our research-based setting, virtual conduct of most of the study procedures allowed pt flexibility. Pt outreach to ensure follow-up by contacting through various methods also ensured adherence of >90%. These interventions can be considered for use in other LCS programs to improve adherence to LCS follow-up.
