Referring high-risk individuals for lung cancer screening: A systematic review of interventions with healthcare professionals.

Objective: This systematic review described the effect of interventions aimed at helping Healthcare Professionals refer high-risk individuals for lung cancer screening. Primary outcomes included: lung cancer detection, screening for lung cancer, lung cancer treatments received and lung cancer mortality. Healthcare professionals' knowledge and awareness of lung cancer screening served as secondary outcomes.

Methods: Experimental studies published between January 2016 and 2021 were included. The search was conducted in MEDLINE, CINAHL, ERIC, PsycARTICLES, PsycInfo and Psychology and Behavioral Sciences Collection. The quality of the included studies was assessed using the Mixed Methods Appraisal Tool and the level of evidence was assessed using the Scottish Intercollegiate Guidelines Network grading system.

Results: Nine studies were included. Nurse navigation, electronic prompts for lung cancer screening and shared decision-making helped improve patient outcomes. Specialist screenings yielded more significant incidental findings and a higher percentage of Lung-RADS 1 results (i.e. no nodules/definitely benign nodules), while Primary Care Physician screenings were associated with higher numbers of Lung-RADS 2 results (i.e. benign nodules with a very low likelihood to becoming malignant). An increase in Healthcare Professionals' knowledge and awareness of lung cancer screening was achieved using group-based learning compared to lecture-based education delivery.

Conclusions: The effectiveness of Nurse navigation is evident, as are the benefits of adequate training, shared decision-making, as well as a structured, clear and well-understood referral processes supported by the use of electronic system-incorporated prompts.
