Abstract:
Objective: Despite the known benefits of lung cancer screening (LCS), rates of completion are low. Of further concern are high no-show rates for scheduled screening exams, presenting challenges in balancing early detection with appropriate resource utilization. We identified factors associated with non- or delayed attendance to scheduled LCS exams in order to develop targeted patient interventions.
Methods: We retrospectively reviewed a database of patients referred for LCS between 1/1/2021 and 12/31/2023. Sociodemographic and clinical characteristics were collected, and appointment status of scheduled low-dose CT (LDCT) was reviewed. Patients were categorized as having completed screening if they attended their first CT appointment or completed it within 60 days after no-show or cancellation. Incomplete screening was defined as having never completed an exam or completion greater than 60 days after no-show or cancellation. Factors associated with incomplete screening were identified with multivariable analyses.
Results: A total of 8,399 patients were referred for LCS over the study period. Of these, 5,024 patients were scheduled for LCS, and 4,503 patients (89.6%) were categorized as having completed their LCS exam (Figure 1A). Most patients within this group attended their screening appointment as scheduled (3,618, 80.3%), while 15.0% (N=675) attended their LDCT within 60 days of a cancellation and 4.7% (N=210) had a no-show event and subsequently completed screening within 60 days. Alternatively, 521 patients (10.4% of all patients scheduled) were categorized as having incomplete screening, whereby 25 patients completed after 60 days following a no-show, 24 completed after 60 days following a cancellation, and 472 never completed LDCT. On multivariable analysis, older age, female sex, married status, former smoker status as opposed to current smoker and undergoing shared decision-making (SDM) were significantly associated with likelihood of completing LCS (Figure 1B).
Conclusions: As eligible patients are scheduled for LDCT, continued programmatic efforts are needed to ensure screening exams are completed. Patients at risk for incomplete screening include younger patients, those not married, men, current smokers and absence of SDM. Further understanding of these barriers has helped us identify patients for a randomized trial for targeted intervention which we anticipate will improve compliance for LCS completion.
