Previously, we demonstrated that 21% of pediatric (<16 years) trauma deaths in the Province of Ontario during the period 1985 to 1987 were potentially preventable. Since then many trauma system changes have occurred including field triage, designation of trauma centers, and improved injury prevention. This study aims to examine the current preventable trauma death rate in our system using identical methodology to our previous study.
The records of all children (<16 years) who died in Ontario from 2001 to 2003 after blunt or penetrating trauma were obtained from the Chief Coroner and compared with those in our previous report. In both series, we excluded cases where care was not sought and all deaths due to asphyxia. Deaths were considered unpreventable if the Injury Severity Score, based on Abbreviated Injury Scale 1985, was >59; or if there was a head injury that received an Abbreviated Injury Scale score of 5 with the exception of isolated extra-axial hematomas.
Eleven preventable deaths were identified. The preventable death rate was 7%, a significant decline from the 21% previously identified (p < 0.001; relative risk reduction for preventable death, 68% [95% confidence interval, 42-83%]; number needed to treat, 7).
There has been a threefold decline in the preventable death rate, which we believe is related to improvements in the trauma system. We estimated that, for every seven deaths from fatal injuries, system changes between the two study periods eliminated one preventable death.
此前,我们证明了1985年至1987年期间安大略省21%的儿科(<16岁)创伤死亡是有可能预防的。自那时以来,创伤系统发生了许多变化,包括现场分诊、创伤中心的指定以及改进的伤害预防措施。本研究旨在使用与我们之前研究相同的方法来检查我们系统中当前可预防的创伤死亡率。
从首席验尸官处获取了2001年至2003年在安大略省因钝器或穿透性创伤死亡的所有儿童(<16岁)的记录,并与我们之前报告中的记录进行了比较。在这两个系列中,我们排除了未寻求治疗的病例以及所有因窒息导致的死亡。如果根据1985年简略损伤量表得出的损伤严重程度评分>59;或者如果存在头部损伤且简略损伤量表评分为5,但孤立的轴外血肿除外,则死亡被认为是不可预防的。
确定了11例可预防的死亡。可预防死亡率为7%,与之前确定的21%相比有显著下降(p<0.001;可预防死亡的相对风险降低68%[95%置信区间,42 - 83%];需治疗人数为7)。
可预防死亡率下降了两倍,我们认为这与创伤系统的改善有关。我们估计,在每7例致命伤死亡病例中,两个研究期间的系统变化消除了1例可预防的死亡。
