Our aim was to ascertain the extent of under-reporting of seriously injured motor vehicle traffic crash victims, as recorded by police in New Zealand, and to what extent this coverage was biased by crash, injury, demographic, and geographic factors. Hospital data and police records were linked using probabilistic methods. During 1995, less than two-thirds of all hospitalised vehicle occupant traffic crash victims were recorded by the police. Reporting rates varied significantly by age, injury severity, length of stay in hospital, month of crash, number of vehicles involved, whether or not a collision occurred, and geographic region, but not by gender, ethnicity or day of the week of the crash. Those using these police files for prioritization, resource allocation and evaluation purposes need to be aware of the extent and nature of these biases contained within these databases.
我们的目标是确定新西兰警方记录的严重受伤机动车交通事故受害者漏报的程度，以及这种覆盖范围在多大程度上受到事故、伤害、人口统计学和地理因素的影响。利用概率方法将医院数据与警方记录相链接。1995年期间，警方记录的住院车辆驾乘人员交通事故受害者不到总数的三分之二。报告率因年龄、伤害严重程度、住院时间、事故发生月份、涉事车辆数量、是否发生碰撞以及地理区域而有显著差异，但不受性别、种族或事故发生星期几的影响。那些将这些警方档案用于确定优先级、资源分配和评估目的的人需要了解这些数据库中所含偏差的程度和性质。
