摘要

Objective

This study aimed to investigate the impact of the type and number of prehospital interventions, in addition to prehospital time intervals, on inhospital mortality among trauma patients.

Methods

According to a 13-year prospective trauma registry, three prehospital time intervals of response time, on-scene time, and transport time were assessed. Prehospital interventions were classified into four categories: stop bleeding strategies, immobilization, basic airway management, and advanced resuscitation.

Results

A total of 13,533 patients were included. Relative to patients not receiving prehospital interventions, there was longer on-scene time for those who received immobilization (10.4 vs. 8.68 min), basic airway management (11.4 vs. 9.40 min), and advanced resuscitation (12.6 vs. 9.53 min). Furthermore, relative to patients who survived in hospital, those who died significantly had longer on-scene time (11.4 vs. 9.64 min) and sustained immobilization (74.7% vs. 52.5%), basic airway management (30.7% vs. 7.6%), advanced resuscitation (32.0% vs. 0.1%), and ≥ 4 prehospital interventions (30.4% vs. 4.6%). Results of the multivariable logistic regression analysis shows that without adjustment for type and number of prehospital interventions, longer on-scene time (odds ratio [OR] = 1.03; 95% confidence interval [CI], 1.01–1.04) were significantly associated with increased mortality; however, after additional adjustment for type and number of prehospital interventions, no significant association between each of the three prehospital time intervals and mortality was detected. Furthermore, compared to patients who did not receive prehospital interventions, those who received wound packing/compression had a significantly lower risk of mortality (OR = 0.54; 95% CI, 0.36–0.80), whereas those who received basic airway management (OR = 1.73; 95% CI, 1.15–2.60), advanced resuscitation (OR = 33.4; 95% CI, 14.9–75.0), and three (OR = 2.60; 95% CI, 1.01–6.93) and ≥ 4 (OR = 2.97; 95% CI, 1.01–9.63) prehospital interventions had a significantly higher risk of mortality.

Conclusions

There exists a tradeoff between prehospital trauma interventions and shortening on-scene time for mortality risk; however, implementing some interventions for hemorrhage control and hemostatic resuscitation can benefit the survival of trauma patients the most.
