Reply to Letter to the Editor: The Association of Mobile Medical Team (MMT) Involvement on On-Scene-Times and Mortality in Trauma Patients.

摘要

We kindly thank Dr. Schober et al. for their comments and respond to the three main issues raised. First, one of the most important conclusions from our study is that in general the on-scene times (OST) are too long when compared with the Pre-Hospital Trauma Life Support recommendations. In >90% of all trauma patients, the OST was longer than the 10 minutes recommended. Involvement of Mobile Medical Team (MMT) increased the OST even further. This phenomenon was also seen in a more recent study by Frankema et al., who found a prolongation of OST by 9 minutes with MMT involvement after correction for patient and injury characteristics. In their letter, Schober et al. acknowledged that the prolongation of OST was significant but thought it was probably of minor clinical relevance. This is speculative, and in addition the abovementioned study by Frankema et al. showed that there was a higher unconnected chance of dying with increasing OST by 10 minutes.1 We agree with Schober et al. that a potential reason for the longer OST could be because of secondary dispatch, the higher intervention rate, or extrication of victims which we could not assess. However, whatever the reason, MMT involvement did prolong the OST without positive or negative effects on mortality.
