AbstractAbstract AbstractSummary PDFSupplementary Material
Through a survey on perception of lung cancer screening and accompanying medical radiation exposure in Korea, the present study was to investigate its current situations and evaluate various perception of physicians regarding it in order to propose measures for improvements.
Medical specialists in national cancer screening institutions selected through stratified random sampling were subjected to face-to-face interview using a structured questionnaire. We investigated physicians’ perception on effectiveness of lung cancer screening depending on screening modality, selection criteria for subjects of screening, types of equipment used to screen, and perception for seriousness of adverse effects following the test. In addition, odds ratios to underestimate risk of radiation exposure from screening were calculated through logistic regression analysis.
Each response that chest X-ray is effective for lung cancer screening and that smoking history is not considered prior to screening recommendation accounted for more than 60% of respondents, suggesting the chance of unnecessary screening tests. Regarding adverse effects of lung cancer screening, about 85% of respondents replied that false positive, radiation exposure, and overdiagnosis could be ignored. About 70% of respondents underestimated radiation dose from lung cancer screening, and a low proportion of physicians informed patients of radiation exposure risk.
It was found that most physicians underestimated harms of lung cancer screening including radiation exposure and were lack of awareness regarding lung cancer screening. It should be noted that physicians need to have proper perceptions about screening recommendation and accompanying possible harms, for successful implementation of the screening program.
Korean summary
전국 100여개 국가암검진 기관을 대상으로 폐암검진 관련 설문을 수행한 결과, 효과적인 폐암검진의 수단이나 방법에 대한 이해 및 검사에 수반되는 각종 부작용에 대한 의사들의 인식이 확연히 부족한 것으로 조사되었다. 그 중에서도 특히 의료방사선 노출에 대한 낮은 인지도는, 촬영 시 피폭량에 대한 전반적인 과소평가 및 방사선 노출 위험과 관련한 환자 교육의 부재를 통해 확인할 수 있었다. 인구집단 대상 선별검사의 도입에 따른 잠재적인 위해 가능성과 그 결과에 대한 고민은 반드시 필요하며, 이와 관련된 의료제공자들의 인식 개선을 촉구하는 본 연구는 정책 도입에 앞서 선결되어야 할 과제로서 공중보건학적 측면에서 중요한 의의를 지닌다.
