The Injury Severity Score or the New Injury Severity Score for predicting intensive care unit admission and hospital length of stay?

Comparison Of Trauma Scores For Predicting Mortality And Morbidity On Trauma Patients

“…Lavoie et al [21] compared NISS with ISS among patients with moderate and severe head trauma for the ICU admission and length of hospital stay, and NISS was found to be better than ISS for the prediction. In our study, ICU need was predicted by all trauma scores significantly, but NISS was more successful.…”

Ten years of new injury severity score (NISS): is it a possible change?

“…The 19 studies comparing NISS and ISS were assessed thoroughly by its full reading (3)(4)(5)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23) . Of these, Despite this diversity of countries, the USA had the greatest number of publication (68.5%).…”

A New Approach to Outcome Prediction in Trauma: A Comparison With the TRISS Model

“…The large amount of missing cases in the present form of the TRISS model necessitates a new statistical model for outcome prediction based on accessible data. 6 There is an abundant literature on how to modify the TRISS model by using different injury scoring 7,8 such as the New Injury Severity Score (NISS), the Anatomic Profile Score (APS), the Modified Anatomic Profile (mAP), and the International Classification of Disease-Based Severity Score (ICISS). Models for specific subsets of trauma patients such as intubated patients, 9 patients with penetrating injuries 10 or children 11 were also developed using the TRISS methodology.…”
