The goal of this study was to provide national estimates of the frequency and cost of school injuries.
Six years of National Health Interview Survey data were used to estimate nonfatal injury incidence rates, multiple sources were used to estimate fatalities, and national highway crash data were used to estimate school bus injury incidence.
Each year, 3.7 million children suffer a substantial injury at school, resulting in an estimated $3.2 billion in medical spending and $115 billion in good health lost. Nonschool fatalities greatly exceed school fatalities; from an incidence per hour perspective, however, school hours are no safer than nonschool hours despite greater formal supervision. School bus injuries account for half of school injury deaths but less than 1% of total school injury costs.
Nonfatal injury is a problem in schools. The concentration of injury at secondary schools suggests that interventions there may be most cost-effective. Data on school injury causes are greatly needed.
本研究的目的是提供全国范围内学校伤害的发生频率和成本估算。
使用六年的全国健康访谈调查数据来估算非致命伤害发病率,利用多个来源估算死亡人数,并使用国家公路碰撞数据来估算校车伤害发病率。
每年有370万儿童在学校遭受严重伤害,导致估计32亿美元的医疗支出和1150亿美元的健康损失。校外死亡人数大大超过校内死亡人数;然而,从每小时发病率的角度来看,尽管有更严格的正式监管,但上学时间并不比非上学时间更安全。校车伤害占学校伤害死亡人数的一半,但占学校伤害总成本的不到1%。
非致命伤害是学校存在的一个问题。伤害集中在中学表明,在中学进行干预可能最具成本效益。非常需要有关学校伤害原因的数据。
