Abstract
Objective
This study aimed to evaluate the predictive ability of quick sequential organ failure
assessment (qSOFA) score for in-hospital mortality among patients transported by physician-staffed
helicopters.
Methods
We conducted a single-center, retrospective observational study using the physician-staffed
helicopter registry data between 2003 and 2016. We calculated the qSOFA scores based
on the patients' vital signs, which were measured on the scene. The tool's discriminatory
ability was determined using the area under the curve of the receiver operating characteristic.
Results
A total of 1849 patients with a mean age of 63.0 (standard deviation [SD], 18.4) years
were included in this study. The diagnostic categories included were trauma and nontrauma
cases (1038 [56%] and 811 [44%], respectively). In-hospital mortality was documented
in 169 (9%) patients. Meanwhile, the in-hospital mortality rates among patients with
qSOFA scores of 0, 1, 2, and 3 were 5/411 (1%), 69/797 (9%), 71/541 (13%), and 24/100
(24%), respectively (P < 0.0001 for trend). If the cutoff point is ≥1, the sensitivity and specificity of the
qSOFA scores were 0.97 and 0.24, respectively. The area under the curve of the qSOFA
scores was 0.67 for all patients, whereas that for trauma patients was 0.75.
Conclusion
An increase in the qSOFA score is associated with a gradual increase in the in-hospital
mortality rate among all patients. In particular, a very low mortality rate was observed
among patients with a qSOFA score of 0. The qSOFA score predicted the in-hospital
mortality of patients with trauma well.
