Pilot intervention to increase uptake of lung cancer screening through the emergency department

Abstract

IntroductionThe goal of this study is to demonstrate the feasibility of referring patients for lung cancer screening (LCS) from the emergency department (ED) as a method to increase the uptake of LCS. MethodsThis is a single-arm pilot study at a large safety-net ED. ED LCS-eligible patients were offered a referral to our LCS clinic upon ED discharge. The primary outcome was the frequency at which patients connected with the LCS clinic. ResultsDuring the study period, 105 patients were approached; 26 (24.8%) participated. Reasons for non-enrollment include 29 (27.6%) who were not interested in research, 10 (9.5%) who did not speak English, and 40 (38.1%) who did not meet the pack-years criteria. Seventeen patients (65.4%, 17/26) connected with the LCS clinic, with 10 (38.5%) having been seen in the clinic and received a low dose computed tomography (LDCT) scan. Of the 17 that were connected with the clinic, 7 (26.9%) had a non-LDCT chest CT scan in the past year. Of those that were not seen in the clinic (n = 9), 4 (44.4%) were unreachable via 3 phone calls and a post-marked letter, and 3 (33.3%) did not attend the scheduled appointment, and 2 (22.2%) were delayed due to COVID-19. Of those that had CT scans over the study period (n = 17), 0 scans were normal, one patient (5.9%) had asymptomatic lung cancer, 7 (41.2%) had pulmonary nodules, 11 (64.7%) had emphysema, and 9 (52.9%) had coronary artery disease. ConclusionThis pilot study suggests the feasibility and suggests initial indications of the efficacy of referring ED patients for LCS.
