Overall overtriage and undertriage rates in our trauma patients
| Patients transferred directly to our hospital (by any means of transport) | Patients primarily evaluated in a lower level of healthcare facility and then transferred to our hospital (by any means of transport) | Overall overtriage (O) | Overall undertriage (U) | |
| ISS≤15 | n1=2236 | n2=8 | O=(n1+n2)/ntotal=2244/2320=96.7% | U=n4/ntotal=20/2320=1% |
| ISS>15 | n3=56 | n4=20 | ||
| LOS≤48 hours and non-operative management and final outcome: hospital discharge | n1=2098 | n2=6 | O=(n1+n2)/ntotal=2104/2320=90.7% | U=n4/ntotal=22/2320=1% |
| LOS>48 hours or operative management or final outcome: death | n3=194 | n4=22 |
