Understanding Patient Barriers to Utilization of Low-dose CT Lung Cancer Screening in a High-risk Population

Objective and Hypothesis: The purpose of this study was to assess factors that may affect low-dose CT (LDCT) utilization for lung cancer screening in a diverse population. The authors hypothesized that a lack of medical provider support may contribute to underutilization of LDCT for lung cancer screening. Methods and Materials: A 22-question survey tool was developed and distributed to patients in the radiology department waiting room of a large, urban academic institution over a four-week period. The questionnaire assessed demographics, smoking history, knowledge about LDCT, and potential barriers to getting screened. Data are reported and frequencies. Results: A total of 124 patients responded to the questionnaire. 50% were current or former smokers. 94% of respondents saw their primary care provider within the past year, although 89% said they had not heard about LDCT from their doctors. 90% knew that that smoking is the most common cause of lung cancer, although only 64% knew that lung cancer can be treated successfully at least “sometimes.” 85% reported to be at least somewhat concerned that they or someone they know could die of lung cancer, and 86% were willing to visit their provider to learn more about lung cancer screening. Cost and conflict with work schedules were the most frequently reported reasons for nonadherence to medical appointments. Conclusions: These data identified an information and communication gap related to lung cancer screening with LDCT, especially in a high-risk population. These results support the need to better understand factors contributing to this gap and to reduce barriers to communication and access.
