To evaluate the effect of the voluntary safety standard for liquid laundry packets on the rate of injury involving children younger than 5 years in the United States. Semiannual national estimates of child injuries involving liquid laundry packets treated in US hospital emergency departments were developed for the July 2012 through December 2018 study period. We used a negative binomial regression model to estimate the effect of the voluntary standard on the injury rate following the standard's publication at the end of 2015. The analysis controlled for the rapid growth of laundry packet use during the study period. Results are presented as relative risks and percentage changes in the injury rate. The voluntary standard was associated with a 49.4% to 61.6% reduction in the rate of child injury. The results suggest that the requirements of the voluntary standard have effectively reduced the rate of child injury involving liquid laundry packets and may have prevented 9200 to 23 000 emergency department-treated injuries during the study period.
评估美国自愿安全标准对 5 岁以下儿童液体洗衣袋伤害率的影响。本研究对 2012 年 7 月至 2018 年 12 月期间美国医院急诊部门治疗的儿童液体洗衣袋伤害的半年度全国估计数进行了评估。我们使用负二项回归模型来估计自愿标准在 2015 年底发布后对伤害率的影响。该分析控制了研究期间洗衣袋使用的快速增长。结果以相对风险和伤害率的百分比变化表示。自愿标准与儿童伤害率降低 49.4%至 61.6%相关。结果表明，自愿标准的要求有效降低了涉及液体洗衣袋的儿童伤害率，并且在研究期间可能预防了 9200 至 23000 例急诊治疗的伤害。
