Background: Recent results from the Dutch NELSON study have rekindled debates about the benefit-to-harm ratio of lung cancer screening and the comprehension of this by physicians.
Methods: This research surveyed the perception and understanding of 136 Austrian physicians regarding the advantages and risks of lung cancer screening, examining the impact of educational data visualization tools, including fact box and icon array. Physicians participated in an online survey about their understanding before and after exposure to either a fact box alone or combined with an icon array.
Results: The findings indicated that the fact box significantly enhanced physicians' grasp of the screening's benefits and harms, making them up to 13 times more likely to adjust their estimates within a predefined range. Notably, the intervention was more effective among physicians who initially did not recommend CT screening. However, the addition of the icon array did not offer significant improvement. Postintervention, physicians showcased better comprehension and an improved ability to offer patient-centered advice, which may bolster adherence to lung cancer screening protocols.
Outlook: Despite its insights, the study's cross-sectional nature and the unique cultural context underline the need for more research. Further exploration should focus on different settings and assess the real-world implications on clinical practice and patient outcomes.
