The Centers for Medicare and Medicaid Services (CMS) supports lung cancer screening (LCS) with annual low-dose computed tomography (LDCT) for patients who undergo shared decision-making (SDM) about LCS. Unfortunately, SDM and LCS rates are low in primary care, and, as a result, the potential benefits of LCS are not being realized. The research team interviewed 16 primary care physicians in a large urban medical center (7 in Family and Community Medicine and 9 in Internal Medicine) on their views of SDM and LCS. Interview audio-recordings were transcribed. Coders analyzed the interview transcripts independently using direct content analysis to identify major themes and subthemes. Results of interview analyses show that physicians were aware of LCS but believed that they and their patients would benefit from receiving more information about screening guidelines. Physicians knew about SDM and felt that SDM performance could help to identify issues that are important to patients and may affect their receptivity to LCS. However, many physicians expressed concerns about the time required for SDM and completing SDM about LCS when other issues need to be addressed. They also acknowledged the challenge of engaging patients, especially those with low health literacy, in SDM. In practice, some physicians reported instead of engaging eligible patients in SDM, they simply encourage them to screen. Importantly, most physicians said that they would like to receive training in SDM. Findings from this study indicate that primary care physicians support the dissemination of information about LCS and understand the importance of SDM. Physicians also feel that performing SDM in routine care is challenging but are receptive to additional training in SDM. Health systems should take steps to support SDM and LCS performance in primary care.
