Currently, an estimated 7.9 million US adults use electronic nicotine delivery systems (ENDS). Although published reports have identified fires and explosions related to use of ENDS since 2009, these reports do not provide national estimates of burn injuries associated with ENDS batteries in the US.
We analyzed nationally representative data provided in the National Electronic Injury Surveillance System (NEISS) to estimate the number of US emergency department (ED) visits for burn injuries associated with ENDS batteries. We reviewed the case narrative field to gain additional insights into the circumstances of the burn injury. In 2016, 26 ENDS battery-related burn cases were captured by NEISS, which translates to a national estimate of 1007 (95%CI: 357-1657) injuries presenting in US EDs. Most of the burns were thermal burns (80.4%) and occurred to the upper leg/lower trunk (77.3%). Examination of the case narrative field indicated that at least 20 of the burn injuries occurred while ENDS batteries were in the user's pocket.
Our study provides valuable information for understanding the current burden of ENDS battery-related burn injuries treated in US EDs. The nature and circumstances of the injuries suggest these incidents were unintentional and would potentially be prevented through battery design requirements, battery testing standards and public education related to ENDS battery safety.
目前，估计有790万美国成年人使用电子尼古丁传送系统（ENDS）。尽管自2009年以来已有发表的报告指出了与使用ENDS相关的火灾和爆炸事件，但这些报告并未提供美国与ENDS电池相关的烧伤伤害的全国估计数。
我们分析了国家电子伤害监测系统（NEISS）提供的具有全国代表性的数据，以估计美国急诊室（ED）因ENDS电池相关烧伤而就诊的人数。我们审查了病例描述字段，以进一步了解烧伤伤害的情况。2016年，NEISS记录了26起与ENDS电池相关的烧伤病例，据此推算美国急诊室中此类伤害的全国估计数为1007例（95%置信区间：357 - 1657）。大多数烧伤为热烧伤（80.4%），且发生在上腿部/下躯干（77.3%）。对病例描述字段的审查表明，至少20例烧伤发生在ENDS电池处于使用者口袋中时。
我们的研究为了解美国急诊室治疗的与ENDS电池相关的烧伤伤害的当前负担提供了有价值的信息。伤害的性质和情况表明这些事件是无意的，通过电池设计要求、电池测试标准以及与ENDS电池安全相关的公众教育，有可能预防此类事件。
