Health systems capture injuries using International Statistical Classification of Diseases and Related Health Problems, 10th Revision, Clinical Modification (ICD-10-CM) diagnostic codes and share data with public health to inform injury surveillance. This study analyses provider-assigned ICD-10-CM injury codes among self-reported injuries to determine the effectiveness of ICD-10-CM coding in capturing injury and assault. Methods Self-reported injury screen records from an urban, level 1 trauma centre collected between 20 November 2015 and 30 September 2019 were compared with corresponding provider-assigned ICD-10-CM codes discerning the frequency in which intentions are indicated among patients reporting (1) any injury and (2) assault. Results Of 380 922 patients screened, 32 788 (8.61%) reported any injury and 6763 (1.78%) reported assault. ICD-10-CM codes had a sensitivity of 67.40% (95% CI 66.89% to 67.91%) for any injury and specificity of 89.79% (95% CI 89.69% to 89.89%]). For assault, ICD-10-CM codes had sensitivity of 2.25% (95% CI 1.91% to 2.63%) and specificity of 99.97% (95% CI 99.97% 99.98%). Discussion This study found provider-assigned ICD-10-CM had limited sensitivity to identify injury and low sensitivity for assault. This study more fully characterises ICD-10-CM coding system effectiveness in identifying assaults.

通过ICD-10-CM伤害代码和大型城市急诊室的自我报告伤害探索伤害意图和机制

卫生系统使用疾病和相关健康问题的国际统计分类第 10 版、临床修改 (ICD-10-CM) 诊断代码捕获伤害，并与公共卫生共享数据以告知伤害监测。本研究在自我报告的伤害中分析了提供者指定的 ICD-10-CM 伤害代码，以确定 ICD-10-CM 编码在捕获伤害和攻击方面的有效性。方法 将 2015 年 11 月 20 日至 2019 年 9 月 30 日期间收集的来自城市 1 级创伤中心的自我报告伤害筛查记录与相应的提供者分配的 ICD-10-CM 代码进行比较，以辨别报告患者的意图指示频率（1 ) 任何伤害和 (2) 攻击。结果 在接受筛查的 380 922 名患者中，32 788 名（8.61%）报告有任何伤害，6763 名（1.78%）报告了袭击事件。ICD-10-CM 代码对任何损伤的敏感性为 67.40%（95% CI 66.89% 至 67.91%），特异性为 89.79%（95% CI 89.69% 至 89.89%]）。对于攻击，ICD-10-CM 代码的敏感性为 2.25%（95% CI 1.91% 至 2.63%），特异性为 99.97%（95% CI 99.97% 99.98%）。讨论 本研究发现，提供者指定的 ICD-10-CM 对识别伤害的敏感性有限，对攻击的敏感性较低。这项研究更全面地描述了 ICD-10-CM 编码系统在识别攻击方面的有效性。讨论 本研究发现，提供者指定的 ICD-10-CM 对识别伤害的敏感性有限，对攻击的敏感性较低。这项研究更全面地描述了 ICD-10-CM 编码系统在识别攻击方面的有效性。讨论 本研究发现，提供者指定的 ICD-10-CM 对识别伤害的敏感性有限，对攻击的敏感性较低。这项研究更全面地描述了 ICD-10-CM 编码系统在识别攻击方面的有效性。
