Lung cancer screening knowledge and beliefs among primary care providers and pulmonologists.

191 Background: In response to the National Lung Screening Trial's findings, numerous professional organizations have published guidelines recommending annual lung cancer (LC) screening with low dose computed tomography (LDCT) for eligible patients. In the wake of these guidelines, we sought to assess LC screening practices and beliefs among providers at a large academic medical center.

METHODS: In 2015, we surveyed 54 physicians and 9 residents in pulmonology (27% response rate) and 86 physicians and 100 residents in family/internal medicine (39% response rate). The 23 question Qualtrics survey focused on beliefs and knowledge about LC screening recommendations, guidelines, and practices.

RESULTS: Survey respondents in both groups were mostly White non-Hispanic clinicians with a mean age of 40 (range 28-67). Pulmonology respondents were mostly male (69%) and family/internal medicine respondents were mostly female (53%). The pulmonology group was more likely than family/internal medicine to believe that LC screening is beneficial for patients (p < 0.0001) and cost effective (p = 0.02). Over 76% of the pulmonology group reported ordering a LDCT for an asymptomatic patient in the past 12 months compared to 41% in the family/internal medicine group (p = 0.012). Additionally, 76% in pulmonology were aware of the American College of Chest Physicians recommendations versus 38% in family/internal medicine (p = 0.02). The majority of both groups agreed that an electronic prompt would increase the likelihood of referring a patient for LC screening. While both groups agreed that a LC screening registry would benefit the quality of patient care (100% pulmonology; 65% family/internal medicine; p = 0.02) and make them more likely to refer patients to a LC screening program (88%; 54%; p = 0.04), a significantly larger majority of the pulmonology group held these beliefs.

CONCLUSIONS: Pulmonology respondents had more knowledge of guidelines and more favorable opinions of LC screening than family/internal medicine respondents. Our findings suggest future studies should focus on educating providers about recommendations and understanding why the family/internal medicine group is less likely to refer patients for LC screening.
