The needs and expectations of people eligible for lung cancer screening in Switzerland: A mixed method study

Organized lung cancer screening is being considered in Switzerland. This study assesses knowledge, barriers, and expectations regarding screening among the population and healthcare professionals prior to a pilot project. A convergent, mixed method approach combined an online survey, focus groups and interviews with laypeople aged 50–79 years with a smoking history and healthcare professionals. Data were collected between June and August 2023 in the Canton of Vaud, Switzerland. Among 952 survey respondents (79% women, 60% current or ex-smokers), 19% were aware of lung cancer screening, but 75% would participate if offered.Responders preferred information from general practitioners (72%) or official letters (46%). In qualitative interviews, the 24 participants emphasized clear, non-stigmatizing, emotionally engaging communication, accessible logistics, and supportive professional guidance. Eligibility criteria were often viewed as too restrictive. The implementation of lung cancer screening in Switzerland will require a multichannel communication campaign, training and tools for healthcare professionals, and clear eligibility criteria using a pedagogical approach. • Study of lung cancer screening implementation in Switzerland. • Awareness of lung cancer screening was low, but willingness to participate was high. • Participants call for clear, non-stigmatizing information via primary care doctors. • Implementation requires multichannel communication and smoking cessation support.
