To demonstrate trends in trauma care in England and Wales from 1989 to 2000.
Database of the Trauma Audit and Research Network that includes hospital patients admitted for three days or more, those who died, were transferred or admitted to an intensive care or high dependency area.
To demonstrate trends in outcome, severity adjusted odds of death per year of admission to hospital were calculated for all hospitals (n=99) and 20 hospitals who had participated since 1989 (adjustments are for Injury Severity Score, age, and Revised Trauma Score). The grade of doctor initially seeing the injured patient in accident and emergency and median prehospital times per year of admission were calculated to demonstrate trends in the process of care. Trend analyses were carried out using simple linear regression (odds ratio versus year).
The analysis shows a significant reduction in the severity adjusted odds of death of 3% per year over the 1989-2000 time period (p=0.001). During the period 1989-1994 the odds of death declined most steeply (on average 6% per year p=0.004). Between 1994 to 2000 no significant change occurred (p=0.35). This pattern was mirrored by the 20 permanent members where the odds of death also declined more steeply over the 1989-1994 period. The percentage of severely injured patients (ISS >15) seen by a consultant increased from 29 to 40 from 1989-1994 but has remained static subsequently. Median prehospital times for severely injured patients have not changed significantly since 1994 (51 to 45 minutes).
Most of the case fatality reduction for trauma patients reaching hospital over the 1989-2000 time period occurred before 1995 when there was most marked change in the initial care of severely injured patients.
为了展示1989年至2000年英格兰和威尔士创伤护理的趋势。
创伤审计与研究网络数据库,包括住院三天或更长时间的医院患者、死亡患者、转院患者或入住重症监护或高依赖区域的患者。
为所有医院(n = 99)和自1989年以来参与的20家医院计算每年入院时经严重程度调整后的死亡比值比,以展示结局趋势(调整因素为损伤严重程度评分、年龄和修订创伤评分)。计算每年入院时在急诊室最初诊治受伤患者的医生级别以及院前中位时间,以展示护理过程的趋势。使用简单线性回归(比值比与年份)进行趋势分析。
分析显示,在1989 - 2000年期间,经严重程度调整后的死亡比值比每年显著降低3%(p = 0.001)。在1989 - 1994年期间,死亡比值比下降最为陡峭(平均每年6%,p = 0.004)。1994年至2000年期间未发生显著变化(p = 0.35)。20家常任成员医院也呈现出类似模式,在1989 - 1994年期间死亡比值比同样下降更为陡峭。1989 - 1994年期间,由顾问诊治的重伤患者(损伤严重程度评分>15)比例从29%增至40%,但此后保持稳定。自1994年以来,重伤患者的院前中位时间无显著变化(从51分钟降至45分钟)。
1989 - 2000年期间,大多数送达医院的创伤患者病死率降低发生在1995年之前,当时重伤患者的初始护理发生了最显著的变化。
