There is sparse literature regarding K-9 (legal intervention) dog bites. It was the purpose of this study to analyze the demographics of K-9 dog bites using a national data base.
This was a retrospective study of prospectively collected data from National Electronic Injury Surveillance System - All Injury Program for years 2005-2013. Patients with dog bites were identified and those due to legal intervention were analyzed. Statistical analyses were performed with SUDAAN 11.0.01™ software. A p < 0.05 was considered statistically significant.
There were an estimated 32, 951 K-9 dog bite ED visits, accounting for 1.1% of all ED dog bite visits. The K-9 group was nearly all male (95.0 vs 52.1%) and more commonly Black (42.0 vs 13.0%) compared to the non K-9 group. Bites to the head/neck and upper extremity were less frequent and lower extremity bites more frequent in the K-9 group; K-9 bites more commonly occurred outside the home. Within the K-9 group, the proportion of White patients increased with increasing age and smaller hospital size. Patients seen in small and medium size hospitals were in the middle age ranges, while those in the very young and >64 years of age were only seen at large hospitals. The average annual incidence of K-9 dog bites seen in the ED for US was 2.43 per 100,000 males with no changes over time.
In the US, 1.1% of all ED visits for dog bites are due to K-9 intervention with no change in incidence, even though this study spanned the time when it was encouraged to change K-9 intervention; from "find and bite" to "find and bark". The K-9 dog bite patient is nearly always male, more commonly Black, occurred away from home, and has a 3.7% hospital admission rate. Bites to the head/neck are less common compared to the non K-9 dog bite group.
关于警犬（执法干预）咬伤的文献稀少。本研究旨在利用全国数据库分析警犬咬伤的人口统计学特征。
这是一项对2005年至2013年从国家电子伤害监测系统-所有伤害项目中前瞻性收集的数据进行的回顾性研究。确定被狗咬伤的患者，并对因执法干预导致咬伤的患者进行分析。使用SUDAAN 11.0.01™软件进行统计分析。p<0.05被认为具有统计学意义。
估计有32951次警犬咬伤的急诊就诊，占所有急诊狗咬伤就诊的1.1%。与非警犬组相比，警犬组几乎全为男性（95.0%对52.1%），且黑人更为常见（42.0%对13.0%）。警犬组中，头部/颈部和上肢咬伤较少见，下肢咬伤较常见；警犬咬伤更常发生在家庭以外。在警犬组中，白人患者的比例随年龄增长和医院规模变小而增加。在中小型医院就诊的患者年龄处于中年范围，而非常年轻和64岁以上的患者仅在大型医院就诊。美国急诊中警犬咬伤的年平均发病率为每10万名男性2.43例，且随时间无变化。
在美国，所有狗咬伤急诊就诊中有1.1%是由于警犬干预，发病率没有变化，尽管本研究涵盖了鼓励改变警犬干预方式的时期；从“发现并咬人”到“发现并吠叫”。警犬咬伤患者几乎总是男性，更常见为黑人，发生在离家较远的地方，住院率为3.7%。与非警犬咬伤组相比，头部/颈部咬伤较少见。
