Évaluation des connaissances sur le dépistage du cancer par test de concordance de script

Abstract

Annual screening for lung cancer using low-dose CT-scans is associated with decreased mortality. A survey conducted in Rhône-Alpes area in France found that clinicians need education and information on this topic. Script concordance tests (SCT) are a tool for assessing clinical reasoning in situations of uncertainty. They have not previously been used in France in the context of continuing medical education. We created a questionnaire with 5 multiple-choice questions (MCQ) and two SCT scenarios. The questionnaire was sent to all clinicians and residents who are members of French-Speaking Respiratory Society or the French Young Pulmonologist Association. One hundred and ninety answers were analyzed. Seventy percent stated that decreasing mortality was the best criterion for assessing the effectiveness of a cancer screening policy, and 75% that low-dose CT scan was the best test to achieve this in lung cancer screening. Forty-five percent knew the eligibility criteria of the population, and 62% that low-dose CT scan should be performed annually. Participation in tumor boards and certification in oncology were significantly associated with a better score at MCQ and SCT. SCT and MCQ scores were significantly correlated (Spearman's Rho 0.339; P<0.0001). SCT are feasible by electronic survey and seem relevant. Improving knowledge of clinicians on lung cancer screening is still critical.
