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.

监测尘肺病需要有合理灵敏度的检测 和特异性，加上对个人的预防性干预 工人以及一般的工作场所。《国际劳工报》 国际劳工组织(劳工组织)对尘肺胸片进行分类的系统 国际疾病控制与预防中心(ICRP)已被公认为是一种流行病学工具。当前的系统 需要使用22个胶片。访问这些电影是有限的，因为 复制、分发的成本，以及更重要的是 在培训和培训方面需要超过必要投资的系统 申请。工业化和工业化的世界越来越多地 需要一种简单、易用、经济实惠的工具来对放射照片进行分类 肺尘埃沉着病。 我们试图验证一组简单的7张X线片作为监护的使用 射线照相标准集(SRSS)用于分类小的不透明区、大小和 形状。因为这是一个尘肺病监测的工具，验证 将不仅用于对射线照片进行分类，还将用于测试现场 应用可持续发展战略作为监测工作的一部分。 具体目的是检验假设：1)使用七个电影SRSS 可将胸片分为正常或异常(异常的定义为 1/1或更高级别)的敏感性和特异性为65% 以及2)使用七胶片SRSS可以根据以下条件对胸部X线片进行分类 丰满和形状与丰满准确地归类在40% 在65%的分类电影中，只有一个次要类别；以及3)开发和 验证模型培训课程和考试，以开发和测试 使用监视测试的医生的知识、技能和能力 准备好了。
