Implementation and outcomes of lung cancer screening in a community health care system.

e13035 Background: Lung cancer screening using low dose computed tomography (LDCT) in patients meeting criteria is a covered preventative service under the Affordable Care Act and policies of CMS. The purpose of this study is to describe implementation and results of a lung cancer screening program in a community health care system. Methods: We prospectively collected data on all patients obtaining a baseline LDCT scan who enrolled beginning February 2015. Referring provider, smoking history, demographics, comorbidity, findings, and, in those found to have an abnormality, diagnosis were collected. The study was reviewed by the St Joseph Mercy Health System Institutional Review Board and was considered exempt. Results: Over the course of 18 months, 955 patients were referred for a baseline LDCT. 57% were current smokers, 53% were male, and 38% had no comorbid conditions. The mean number of pack-years was 50 (range 6 to 160). 76% of patients were referred by primary care providers. The number of new patients referred per month increased from 8 to 89, largely due to outreach and education directed at primary care physicians and office staff. Of the 955 patients screened, we identified cancer in 2% overall (small cell cancer in 0.2% patients and non-small cell lung cancer (NSCLC) in 1.6%). Among those with NSCLC, 60% had Stage I disease, 20% had Stage II, 13% had Stage III, and 7% had Stage IV disease. Compared to the stage distribution of lung cancer patients identified before the implementation of the screening program, there was significant down-staging in those with NSCLC. Barriers to implementation have included lack of clear smoking history documentation and billing code release delays which led to reimbursement difficulties. Conclusions: Successful implementation of a LDCT lung cancer screening program in a community setting. Improving patient/provider education and documentation of tobacco use in electronic medical records will streamline the referral process and increase screening among eligible patients. Outreach to practices that serve minority and other medically-underserved populations will require specific efforts to achieve health equity in the area of lung cancer screening.
