DESCRIPTION (provided by applicant): Research on penetrating trauma has shown that the early administration of expert care to victims would considerably reduce the number of deaths due to these injuries. Assessment of penetrating trauma requires knowledge of the relationships among human anatomy, physiology and physical manifestations of injury. Tools or knowledge aids that reinforce understanding of these relationships for a patient presenting with penetrating injury may be of value in enhancing patient care. A computer program that integrates anatomic and diagnostic reasoning in assessing a patient could serve as such a tool or knowledge-aid. To address this issue, we have proposed a method for computer-assisted diagnosis of penetrating trauma to the chest and abdomen that assesses anatomical structure involvement in injury based on surface wound location information, and uses this information to drive diagnostic reasoning about the consequences of injury. The method takes into account uncertainty about the extent of damage caused by a mechanism of injury and variability in information available about patient signs, symptoms, and test results. The goal of this proposal is to test the hypothesis that this computer-based method can provide value both as a diagnostic tool, and as an educational one. To assess this, we will conduct a study that retrospectively evaluates a large number of penetrating trauma cases for which the diagnoses are already known, and measure the system's performance in evaluating these cases. We will also examine the system's performance in comparison to physicians at different stages of training, to assess its potential in providing educational value.

描述（由申请人提供）： 对穿透性创伤的研究表明， 对受害者的专家护理将大大减少因 这些伤。 穿透伤的评估需要了解 人体解剖学、生理学和身体表现之间的关系 损伤工具或知识援助，加强对这些 对于出现穿透性损伤的患者， 改善病人护理一个整合了解剖学和 在评估病人时的诊断推理可以作为这样一种工具， 知识援助。 为了解决这个问题，我们提出了一种计算机辅助的方法 胸部和腹部穿透伤的诊断， 基于表面伤口位置的损伤解剖结构受累 信息，并使用这些信息来驱动关于 伤害的后果。 该方法考虑了 损伤机制造成的损伤程度和 关于患者体征、症状和测试结果的可用信息。 这项提案的目的是测试假设，这种基于计算机的 方法可以提供作为诊断工具和作为教育工具的价值。 为了评估这一点，我们将进行一项研究，回顾性地评估一个大型的 已知诊断的穿透性创伤病例数， 并测量系统在评估这些案例时的性能。我们还将 检查系统的性能与医生在不同的 培训阶段，以评估其提供教育价值的潜力。
