Cervical spine injuries (CSI) are a major concern in young pediatric trauma patients. The consequences of missed injuries and difficulties in injury clearance for non-verbal patients have led to a tendency to image young children. Imaging, particularly computed tomography (CT) scans, presents risks including radiation-induced carcinogenesis. In this study we leverage machine learning methods to develop highly accurate clinical decision rules to predict pediatric CSI.
The PEDSPINE I registry was used to investigate CSI in blunt trauma patients under the age of three. Predictive models were built using Optimal Classification Trees, a novel machine learning approach offering high accuracy and interpretability, as well as other widely used machine learning methods.
The final Optimal Classification Trees model predicts injury based on overall Glasgow Coma Score (GCS) and patient age. This model has a sensitivity of 93.3% and specificity of 82.3% on the full dataset. It has comparable or superior performance to other machine learning methods as well as existing clinical decision rules.
This study developed a decision rule that achieves high injury identification while reducing unnecessary imaging. It demonstrates the value of machine learning in improving clinical decision protocols for pediatric trauma.

颈椎损伤(CSI)是年轻儿科创伤患者的主要关注点。由于对未发现的损伤的关注以及对非言语患者清除损伤的困难,导致倾向于对幼儿进行成像。成像,特别是计算机断层扫描(CT)扫描,存在包括辐射致癌在内的风险。在这项研究中,我们利用机器学习方法来开发高度准确的临床决策规则,以预测儿科 CSI。
PEDSPINE I 登记处用于研究三岁以下钝性创伤患者的 CSI。使用最优分类树(一种提供高精度和可解释性的新型机器学习方法)以及其他广泛使用的机器学习方法来构建预测模型。
最终的最优分类树模型基于总体格拉斯哥昏迷评分(GCS)和患者年龄预测损伤。该模型在整个数据集上的敏感性为 93.3%,特异性为 82.3%。它的性能与其他机器学习方法以及现有的临床决策规则相当或更优。
本研究开发了一种决策规则,在减少不必要成像的同时实现了高损伤识别率。它证明了机器学习在改善儿科创伤临床决策方案方面的价值。
