Accuracy of the prehospital triage provided by the GNMS
| Patients transferred directly to our hospital (by the GNMS) | Patients transferred from a lower level of healthcare facility to our hospital (by the GNMS) | GNMS overtriage (O) | |
| ISS≤15 | n1=121 | n2=6 | O=n1/(n1+n3)=121/159=76.1% |
| ISS>15 | n3=38 | n4=20 | |
| LOS≤48 hours and non-operative management and final outcome: hospital discharge | n1=90 | n2=4 | O=n1/(n1+n3)=90/159=56.6% |
| LOS≥48 hours or operative management or final outcome: death | n3=69 | n4=22 |
