E codes classify causes of injury as unintentional, intentional, and undetermined. E-coded discharge data from hospitals provide an opportunity to use this source of morbidity data for planning, implementation, and evaluation of injury and violence prevention activities. This study explores the extent to which E-coded data from hospitals identify injuries that result from violent acts. Cases were identified through a multihospital population-based surveillance system of pediatric injuries. Those cases with injury as a result of violence, designated by study criteria, were compared with those with E codes that were classified as intentional. The analysis indicated that 25 percent of injuries to children resulting from violence may not be accounted for through the use of E codes. The majority of the undetected injury cases resulting from violence involved child abuse. Researchers and other persons who design and conduct injury and violence prevention programs should be aware of the undercount and associated issues when using E-coded hospital discharge data for surveillance of injuries resulting from violence.
E编码将损伤原因分为意外、故意和未确定三类。医院的E编码出院数据为利用这一发病数据来源来规划、实施和评估伤害及暴力预防活动提供了契机。本研究探讨了医院的E编码数据在识别暴力行为导致的损伤方面的程度。通过一个基于多医院人群的儿童损伤监测系统来确定病例。将那些根据研究标准认定为暴力导致损伤的病例与那些E编码被归类为故意的病例进行比较。分析表明，暴力导致的儿童损伤中有25%可能无法通过使用E编码来统计。大多数未被检测到的暴力导致的损伤病例涉及虐待儿童。设计和开展伤害及暴力预防项目的研究人员和其他人员在使用E编码的医院出院数据来监测暴力导致的损伤时，应意识到漏报情况及相关问题。
