Aims: This study explored family physicians’ (FPs) stated practices and decision-making for lung cancer screening.

Methods: Cross-sectional survey of a stratified random sample of Saskatchewan FPs using single item questions and simulated clinical scenarios.

Findings: Wide variations in FPs’ lung cancer screening practices exist in their decision to screen and choice of screening test. Certain physician, patient and non-medical factors influence FPs’ decision-making contrary to their perception of guidelines.

Conclusions: The high self-reported prevalence and measured inclination to screen in clinical scenarios contrary to prevailing guidelines adds unnecessary health care costs and has potential to cause harm.

Significance: First and unique study regarding lung cancer screening in family practice in Canada. It contributes to the literature about existing FP practices and decision-making regarding lung cancer screening and highlights implications to health care cost, patient care and CME initiatives.
