Real-world lung cancer screening decision-making: Barriers and facilitators

Abstract

ObjectiveTo explore 1) attitudes and priorities among physicians and patients that inform shared decision-making about lung cancer screening in real-world settings and 2) physician and patient perceptions of shared decision-making in real-world lung cancer screening (LCS) practice. Materials and methodsWe conducted a qualitative study of 12 physicians and 30 patients meeting LCS screening criteria established by the US Preventative Services Task Force (USPSTF) from two academic primary care practices; one university clinic and one safety net clinic. Interview guides focused on knowledge and attitudes about LCS and experiences with patient-physician communication. ResultsPhysicians offered LCS inconsistently and were ambivalent about screening because of potential harms, including false positive results, incidental findings, and radiation exposure. Physicians felt that they were incorporating shared decision-making into screening, although they acknowledged that challenges with screening communication posed barriers to shared decision-making. Patients were generally accepting of lung cancer screening. They expressed fewer concerns about screening-related harms but more personal or emotional concerns related to lung cancer. Patients perceived limited shared decision-making in their encounters, but were generally satisfied with the more physician-directed decision-making process. ConclusionPhysicians and patients expressed different concerns about LCS and different perceptions about the use of shared decision-making. Findings from this real-world population of screening-eligible patients can be used to inform the design of future interventions to facilitate communication and decision-making tailored to perspectives of both physicians and patients.
