Comparing trauma scoring systems to predict mortality in trauma patients

Which Trauma Severity Score (ISS, NISS, RTS, or TRISS) Best Predicts Mortality in Trauma Patients? A Prospective Observational Study

Observational Al-Nahrain University · NCT06709547

This study is testing which of four trauma scoring systems can best predict survival chances for patients with injuries when they arrive at the emergency department.

What this trial studies

This observational study aims to evaluate the effectiveness of four trauma scoring systems—Injury Severity Score (ISS), New Injury Severity Score (NISS), Revised Trauma Score (RTS), and Trauma and Injury Severity Score (TRISS)—in predicting mortality outcomes among trauma patients admitted to the emergency department at Kadhimiya Educational Hospital in Baghdad. Participants will be assessed using these scoring systems upon admission, and their clinical outcomes, including mortality and length of hospital stay, will be monitored throughout their hospital stay. The study seeks to identify which scoring system provides the most accurate predictions and whether certain patient subgroups benefit more from specific scoring methods.

Who should consider this trial

Good fit: Ideal candidates for this study are trauma patients admitted to the emergency room with sufficient documented injury data.

Not a fit: Patients under 18 years of age, pregnant women, and those with non-trauma cases or severe cognitive impairments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the accuracy of mortality predictions in trauma patients, leading to improved patient management and resource allocation.

How similar studies have performed: Other studies have shown varying success with trauma scoring systems, but this specific comparison of the four scoring methods is relatively novel.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Trauma patients admitted to the emergency room (ER).
* Documented injury data sufficient to calculate both the New Injury Severity Score (NISS) and the Injury Severity Score (ISS).
* Trauma scores (ISS, NISS, Revised Trauma Score \[RTS\], and Trauma and Injury Severity Score \[TRISS\]) calculated within 12 hour of arrival to ensure timely predictions.
* Informed consent provided by the patient or a legal guardian in cases of incapacity.

Exclusion Criteria:

* Under 18 years of age and pregnant women, due to differences in trauma management and scoring applicability.
* Non-trauma cases, including patients with terminal illnesses or severe cognitive impairments, to maintain focus on trauma outcomes.
* Incomplete trauma scoring, missing or incomplete medical records, and
* patients not treated in the trauma or emergency department.
* Patients who refuse participation or withdraw consent to ensure ethical participation.
* Transferred patients and those enrolled in other research studies that could interfere with trauma scoring.
