To compare trends in the numbers of people with serious traffic injuries according to police statistics and hospital episode statistics (HES).
Descriptive study based on two independent population based data sources.
Police statistics and hospital episode statistics in England.
Rates of injury and death and their change over time reported in each data source, for 1996 to 2004.
According to police statistics, rates of people killed or seriously injured on the roads fell consistently from 85.9 per 100,000 in 1996 to 59.4 per 100,000 in 2004. Over the same time, however, hospital admission rates for traffic injuries were almost unchanged at 90.0 in 1996 and 91.1 in 2004. Both datasets showed a significant reduction in rates of injury in children aged < or = 15, but the reduction in hospital admission rates was substantially less than the reduction shown in the police statistics. The definition of serious injury in police statistics includes every hospital admission; in each year, none the less, the number of admissions exceeded the number of injuries reported in the police system.
The overall fall seen in police statistics for non-fatal road traffic injuries probably represents a fall in completeness of reporting of these injuries.
根据警方统计数据和医院病历统计数据（HES）比较严重交通伤患者数量的变化趋势。
基于两个独立的人群数据来源进行描述性研究。
英格兰的警方统计数据和医院病历统计数据。
1996年至2004年各数据来源报告的受伤率和死亡率及其随时间的变化。
根据警方统计，道路上死亡或重伤的发生率从1996年的每10万人85.9例持续下降至2004年的每10万人59.4例。然而，在同一时期，交通伤的住院率几乎没有变化，1996年为90.0，2004年为91.1。两个数据集均显示，15岁及以下儿童的受伤率显著下降，但住院率的下降幅度远小于警方统计数据显示的下降幅度。警方统计中重伤的定义包括每次住院；然而，每年住院人数均超过警方系统报告的受伤人数。
警方统计中显示的非致命道路交通伤总体下降可能代表了这些伤害报告完整性的下降。
