Background: Veterans suffer substantial morbidity and mortality from lung cancer. Lung cancer screening (LCS) with low-dose computed tomography (LDCT) can reduce mortality. Guidelines recommend counseling and shared decision-making (SDM) to address the benefits and harms of screening and the importance of tobacco cessation before patients undergo screening.
Observations: We implemented a centralized LCS program at the Iowa City Veterans Affairs Medical Center with a nurse program coordinator (NPC)-led telephone visit. Our multidisciplinary team ensured that veterans referred from primary care met eligibility criteria, that LDCT results were correctly coded by radiology, and that pulmonary promptly evaluated abnormal LDCT. The NPC mailed a decision aid to the veteran and scheduled a SDM telephone visit. We surveyed veterans after the visit using validated measures to assess knowledge, decisional conflict, and quality of decision making. We conducted 105 SDM visits, and 91 veterans agreed to LDCT. Overall, 84% of veterans reported no decisional conflict, and 59% reported high-quality decision making. While most veterans correctly answered questions about the harms of radiation, false-positive results, and overdiagnosis, few knew when to stop screening, and most overestimated the benefit of screening and the predictive value of an abnormal scan. Tobacco cessation interventions were offered to 72 currently smoking veterans.
Conclusions: We successfully implemented an LCS program that provides SDM and tobacco cessation support using a centralized telehealth model. While veterans were confident about screening decisions, knowledge testing indicated important deficits, and many did not engage meaningfully in SDM. Clinicians should frame the decision as patient centered at the time of referral, highlight the importance of SDM, and be able to provide adequate decision support.
