Which injury score better predicts survival? researchers put two tools to the test
NCT ID NCT06705959
First seen Sep 10, 2026 · Last updated Sep 11, 2026 · Updated 1 time
Summary
Researchers are comparing two injury severity scoring systems, the New Injury Severity Score (NISS) and the Injury Severity Score (ISS), to see which one better predicts death in blunt trauma patients. The study enrolls 458 trauma patients admitted to emergency rooms in Iraq. Upon admission, each patient receives both scores, and researchers track outcomes including death during hospitalization and length of stay.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If one scoring system proves more accurate, hospitals could use it to quickly identify the most severely injured patients and prioritize care.
- What could go wrong
- This is an observational study, so it cannot prove that using one score over another saves lives. Results from one conflict-affected region may not apply elsewhere.

Who is studied
The study population will consist of trauma patients aged 18 years and older who are admitted to the emergency room (ER) at Al-Kadhimiya Teaching Hospital in Baghdad, Iraq. This group will include individuals with various types of injuries, such as those from road traffic accidents, falls, and assaults, excluding burns as the primary injury.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Trauma patients admitted to the emergency room (ER). * Patients with documented injury data are sufficient for calculating both the NISS and ISS. * Patients admitted to the ER within 6 hours of injury. * Patients providing informed consent (or consent obtained from a legal guardian in cases of incapacity). Exclusion Criteria: * Patients under 18 years of age. * Trauma cases involving burns as the primary injury. * Patients with incomplete medical records or insufficient data to calculate NISS and ISS. * Patients with pre-existing terminal conditions (e.g., advanced cancer, end-stage organ failure) unrelated to the trauma. * Patients who died on arrival or before NISS/ISS assessment could be performed. * Cases involving pregnant patients, if the primary focus of injury and risk assessment is maternal-fetal outcomes.
