Although loggers in Alaska are at high risk for occupational injury, no comprehensive review of such injuries has been performed since the mid-1990s. We investigated work-related injuries in the Alaska logging industry during 1991-2014.
Using data from the Alaska Trauma Registry and the Alaska Occupational Injury Surveillance System, we described fatal and nonfatal injuries by factors including worker sex and age, timing and geographic location of injuries, and four injury characteristics. Annual injury rates and associated 5-year simple moving averages were calculated.
We identified an increase in the 5-year simple moving averages of fatal injury rates beginning around 2005. While injury characteristics were largely consistent between the first 14 and most recent 10 years of the investigation, the size of logging companies declined significantly between these periods.
Factors associated with declines in the size of Alaska logging companies might have contributed to the observed increase in fatal injury rates.
尽管阿拉斯加的伐木工人面临着很高的职业伤害风险，但自 20 世纪 90 年代中期以来，尚未对这类伤害进行全面审查。我们调查了 1991 年至 2014 年期间阿拉斯加伐木行业的与工作相关的伤害。
利用来自阿拉斯加创伤登记处和阿拉斯加职业伤害监测系统的数据，我们根据工人的性别和年龄、受伤的时间和地理位置以及四个受伤特征描述了致命和非致命伤害。计算了每年的受伤率和相关的 5 年简单移动平均值。
我们发现，自 2005 年左右开始，致命伤害率的 5 年简单移动平均值呈上升趋势。虽然在调查的前 14 年和最近 10 年之间，受伤特征基本一致，但在这两个时期之间，阿拉斯加伐木公司的规模显著下降。
与阿拉斯加伐木公司规模缩小相关的因素可能导致了致命伤害率的上升。
