Abstract

Radiation epidemiology has developed as a specialized field and has unique characteristics compared to the other fields of epidemiology. Radiation exposure assessment is highly quantified and health risk assessment can yield precise risks per unit dose in each organ. At the same time, radiation epidemiology also emphasizes the uncertainty of the estimated doses and risks. More radiation epidemiologists work in radiation societies rather than those of epidemiology. This specialization deepens the research of radiation studies but also results in fragmentation from general epidemiology. In addition to continued involvement with radiation-related sciences, therefore, more efforts to communicate with the other fields of epidemiology are necessary for radiation epidemiology.

Summary

Korean summary
방사선 역학은 역학의 세부 전공분야로서 다른 역학 분야와 구별되는 특성들이 있다. 노출 및 건강영향 평가에서의 정량화된 접근방법을 비롯하여 방사선 역학의 많은 장점들은 다른 역학분야에서도 응용될 필요가 있다. 이러한 전문화는 역학 연구의 내용을 깊게 발전시키는데 큰 역할을 하고 있는 반면, 일반 역학 분야와 분열되는 단점도 있다. 따라서 기존 방사선 관련 학문들과의 지속적인 교류뿐 아니라 다른 역학분야와의 활발한 교류를 통해 방사선 역학 및 전체 역학분야를 발전시키는 것이 중요하다.

Abstract

OBJECTIVES
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.

METHODS

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.

RESULTS

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.

CONCLUSIONS

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.

Summary

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.
