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.
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.
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%).
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.
健康系统使用国际疾病分类第十版临床修订版（ICD-10-CM）诊断代码来捕获伤害，并与公共卫生共享数据，以告知伤害监测。本研究分析了自我报告的伤害中提供者分配的 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。
比较了 2015 年 11 月 20 日至 2019 年 9 月 30 日期间从一个城市一级创伤中心收集的自我报告伤害筛选记录与相应的提供者分配的 ICD-10-CM 代码，以确定报告（1）任何伤害和（2）攻击的患者中意图的频率。
在 380922 名筛查患者中，32788 名（8.61%）报告有任何伤害，6763 名（1.78%）报告有攻击。ICD-10-CM 代码对任何伤害的敏感性为 67.40%（95%CI66.89%至 67.91%），特异性为 89.79%（95%CI89.69%至 89.89%）]。对于攻击，ICD-10-CM 代码的敏感性为 2.25%（95%CI1.91%至 2.63%），特异性为 99.97%（95%CI99.97%至 99.98%）。
本研究发现，提供者分配的 ICD-10-CM 对识别伤害的敏感性有限，对攻击的敏感性较低。本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。
