EVALUATION OF A SURVEILLANCE RADIOGRAPH STANDARDS SET

肺尘病的监测需要一个具有合理灵敏度的测试 和特异性，再加上对个人的预防性干预措施， 工人，以及一般的工作场所。国际劳工 国际劳工组织（ILO）肺尘埃沉着病胸部X光片分类系统 （ICRP）是一种流行病学工具。当前系统 需要使用22部电影。 这些电影的访问是有限的，因为 复制、分发的成本，以及重要的是， 这一系统需要在培训方面进行超过必要的投资， 应用程序. 越来越多的工业化和工业化世界有一个 需要一种简单、易用、成本效益高的工具来对射线照片进行分类 肺尘埃沉着病 我们试图验证使用一组简单的7张X光片作为监督 X线片标准集（SRSS），用于对小的不透明性、大小和 形状因为这是尘肺病监测的工具， 将不仅仅是对射线照片进行分类， 作为监督工作的一部分，应用SRSS。 具体目的是检验以下假设：1）使用七部电影的SRSS 可以将胸片分类为正常或异常（异常定义为 灌注分类1/1或更高），灵敏度和特异性为65% 和2）使用七片SRSS可以根据以下内容对胸片进行分类： 丰富度和形状，丰富度被正确分类，准确率为40% 在65%已分类的影片中， 验证示范培训课程和考试，以制定和测试 使用监测测试的医生的知识、技能和能力 集

Surveillance for pneumoconioses requires a test with reasonable sensitivity and specificity coupled with preventive interventions for the individual worker as well as the work place in general. The International Labor Organization (ILO) System to Classify Chest Radiographs for Pneumoconioses (ICRP) is well established as an epidemiologic tool. The current system requires the use of 22 films. Access to these films is limited due to the cost of reproduction, distribution, and importantly the complexity of the system which requires greater than necessary investments in training and application. Increasingly, the industrialized and industrializing world has a need for a simple, easy to use, cost effective tool to classify radiographs for pneumoconiosis. We seek to validate the use of a simple set of 7 radiographs as a Surveillance Radiograph Standards Set (SRSS) to classify small opacity profusion, size and shape. Because this is a tool for pneumoconiosis surveillance, the validation will be not just for classifying radiographs, but to test the field application of the SRSS as part of surveillance exercise. The specific aims are to test the hypotheses: 1) Use of the seven film SRSS can categorize chest radiographs as normal or abnormal (abnormal defined as profusion categories 1/1 or greater) with a sensitivity and specificity of 65% and 2) Use of a seven film SRSS can classify chest radiographs according to profusion and shape with profusion being correctly categorized exactly in 40% and within one minor category in 65% of films classified; and 3) Develop and validate a model training curriculum and examination to develop and test the knowledge skills and competencies of physicians using the surveillance test set.
