An increase in the recreational use of personal watercraft (PWC) raises concern about an increase in associated injuries on a national level.
To estimate the relative frequency, types of injury, and demographic features of persons injured while using PWC in the United States.
Case series.
Emergency department (ED) visits to hospitals participating a national probability sample.
All persons treated for PWC-related injury from January 1,1990, through December 31, 1995.
An estimated 32954 persons (95% confidence interval [CI], 22919-42989) with PWC-related injuries were treated in US hospital EDs, of which 3.5% were hospitalized. Personal watercraft-related injuries have increased significantly from an estimated 2860 in 1990 to more than 12000 in 1995. During this period, the number of PWC in operation increased 3-fold from approximately 241500 in 1990 to an estimated 760000 in 1995. The most prevalent diagnoses were lacerations, contusions, and fractures.
The estimated number and percentage of patients treated in EDs for PWC-related injuries, by year, age, sex, and the number and rate per 1000 of PWC in operation by year.
Since 1990, there has been at least a 4-fold increase in injuries associated with an increase in the recreational use of PWC. The rate of ED-treated injuries related to PWC was about 8.5 times higher (95% CI, 8.2-8.8; 1992 data) than the rate of those from motorboats. Specific training and adult supervision is recommended for minors using PWC. Furthermore, medical practitioners should encourage personal flotation device use and other protection for their patients who are known water enthusiasts.
个人水上摩托艇（PWC）娱乐用途的增加引发了对全国范围内相关伤害增加的担忧。
估计在美国使用PWC时受伤人员的相对频率、伤害类型和人口统计学特征。
病例系列研究。
参与全国概率抽样的医院急诊科就诊情况。
1990年1月1日至1995年12月31日期间因PWC相关伤害接受治疗的所有人员。
估计有32954人（95%置信区间[CI]，22919 - 42989）因PWC相关伤害在美国医院急诊科接受治疗，其中3.5%住院治疗。与个人水上摩托艇相关的伤害从1990年估计的2860例显著增加到1995年的12000多例。在此期间，运营中的PWC数量从1990年约241500艘增加了3倍，到1995年估计为760000艘。最常见的诊断是撕裂伤、挫伤和骨折。
按年份、年龄、性别划分的在急诊科接受PWC相关伤害治疗的患者估计数量和百分比，以及按年份划分的每1000艘运营中的PWC的数量和比率。
自1990年以来，随着PWC娱乐用途的增加，相关伤害至少增加了4倍。因PWC导致的急诊科治疗伤害率比摩托艇导致的伤害率高约8.5倍（95% CI，8.2 - 8.8；1992年数据）。建议对使用PWC的未成年人进行特定培训并由成年人监管。此外，医生应鼓励已知的水上运动爱好者患者使用个人漂浮装置及采取其他保护措施。
