To describe one urban trauma transport system to clarify the impact of transport by nonmedical personnel on patient outcome.
Retrospective data were assembled over a six-year period through the use of the state trauma registry for an urban county served by seven state-accredited trauma centers. A subset of 4,767 consecutive assaulted patients was analyzed using the TRISS method to estimate survival probability. An unexpected death index (UDI), calculated as the difference between expected (TRISS method) and observed death rates, also was determined. Outcomes for patients transported by fire medics (FMs) vs nonmedical, police personnel (NPs) were compared.
FMs transported 2,108 (44%) and NPs transported 1,356 (29%) of the injured assault victims. The FM-transported patients had a lower expected probability of survival than had the NP-transported patients (p < 0.001). This also was true within the penetrating-injury subgroup (p < 0.001), but not the blunt-injury subgroup. The observed death rate was higher for all the FM-transported patients than it was for the NP-transported patients (15% vs 11%; p < 0.01). The UDIs were not different overall, although the NP-transported patients who had blunt trauma had a significantly lower UDI (p < 0.01).
NP transport of assaulted patients is generally associated with equivalent outcomes in comparison with FM transport in this urban environment. However, these data also provide evidence of an on-scene implicit triage with more severely injured patients generally transported by FMs.
描述一种城市创伤转运系统,以阐明非医务人员转运对患者结局的影响。
通过使用州创伤登记系统,收集了一个由七个获得州认证的创伤中心服务的城市县在六年期间的回顾性数据。使用TRISS方法分析了4767例连续受攻击患者的子集,以估计生存概率。还确定了意外死亡指数(UDI),计算方法为预期(TRISS方法)死亡率与观察到的死亡率之间的差值。比较了由消防医护人员(FM)和非医务人员、警察(NP)转运的患者的结局。
FM转运了2108例(44%)受伤的攻击受害者,NP转运了1356例(29%)。FM转运的患者的预期生存概率低于NP转运的患者(p<0.001)。在穿透伤亚组中也是如此(p<0.001),但在钝性伤亚组中并非如此。所有FM转运的患者的观察到的死亡率高于NP转运的患者(15%对11%;p<0.01)。总体上UDI没有差异,尽管遭受钝性创伤的NP转运患者的UDI显著较低(p<0.01)。
在这个城市环境中,与FM转运相比,NP转运受攻击患者的结局通常相当。然而,这些数据也提供了现场隐性分诊的证据,即伤势较重的患者通常由FM转运。
