Training to identify red flags in the acute care of trauma: who are the patients at risk for early death despite a relatively good prognosis? An analysis from the TraumaRegister DGU®.

BACKGROUND

In the acute care of trauma, some patients with a low estimated risk of death die suddenly and unexpectedly. In this study, we aim to identify predictors for early death within 24 h following hospital admission in low-risk patients.

METHODS

The TraumaRegister DGU® was used to collect records of patients who were primarily treated in a participating hospital between 2004 and 2013 with a RISC II score below 10%.

RESULTS

During the study period, 64,379 patients met the inclusion criteria. The mean RISC II score was 2.0%, and the mean ISS was 16 ± 9. The overall hospital mortality rate was 2.1%, and 0.5% of patients (n = 301) died within the first 24 h. A SPB of ≤ 90 mmHg was associated with an increased risk of death (p < 0.001). An AIS abdomen score of ≥ 3 was associated with increased risk of death within the first 24 h (p < 0.001). A high risk of early death was also seen in patients with an AIS score (thorax) ≥ 3; 51% of those who died died within the first 24 h (p < 0.005). Death in patients over 60 years was more common after 24 h (p < 0.001). Patients with an ASA score of ≥ 3 were more likely to die after the first 24 h (p < 0.001).

CONCLUSIONS

Indicators predicting a high risk of early death in patients with a low RISC II score include a SPB ≤ 90 mmHg and severe chest and abdominal trauma. Emergency teams involved in the acute care of trauma patients should be aware of these "red flags" and treat their patients accordingly.
