New injury severity score (NISS) outperforms injury severity score (ISS) in the evaluation of severe blunt trauma patients

Abstract: Purpose The injury severity score (ISS) and new injury severity score (NISS) have been widely used in trauma evaluation. However, which scoring system is better in trauma outcome prediction is still disputed. The purpose of this study is to evaluate the value of the two scoring systems in predicting trauma outcomes, including mortality, intensive care unit (ICU) admission and ICU length of stay. Methods The data were collected retrospectively from three hospitals in Zhe… Show more

“…Septic shock, APACHE II score on admission, SOFA score, and MODS were independent risk factors of death for patients with post-traumatic sepsis. ISS is the most commonly used tool for stratification of injured patients and have been widely used in trauma evaluation, which presents excellent performance in predicting mortality caused by blunt trauma when the patients' ISS are lower than 25 [ 27 ]. In 1999, SOFA was applied to evaluate organ dysfunction in trauma patients and associated with prediction of prolonged ICU stay or death [ 28 ].…”

“…The cohort's median TRISS survival percentage was 98.4% (IQR, 96.6-99.3%) with those who survived at 98.6% (IQR, 97-99.3%) and those who died at 88.9% (IQR, 64.7-97.7%). The cohort's median GCS was 15 (IQR, [13][14][15] with those who survived at 15 (IQR, 14-15) and those who died at 13 (IQR, [3][4][5][6][7][8][9][10][11][12][13][14][15]. The cohort's mean ± SD SI was 0.88 ± 0.4 with those who survived at 0.85 ± 0.12 and those who died at 1.17 ± 0.19.…”

“…[7][8][9] In addition, NISS was superior to ISS when predicting for mortality and complications of penetrating trauma patients. 10,11 The significance of these trauma scoring systems in influencing patient care makes constant reevaluations and improvements an imperative. This is especially true when taking a historical context.…”

“…Ranging from an increased incidence of secondary complications to discharge to specialised care facilities, critically ill patients with an extended ICU LOS experience poor short and long-term clinical outcomes [6,8]. In paediatric and adult trauma settings, several groups have investigated whether an assessment of injury severity at hospital presentation can aid in the identification of patients at risk of a prolonged ICU LOS [17][18][19]42].…”

“…These factors include male gender [9], increased age [6,9,10], pre-existing co-morbidities [6], higher injury severity [6,9,10], severe head injury [6,[10][11][12], surgical procedures [10] and nosocomial infection [9,10]. While an assessment of injury severity at hospital arrival, using either the injury severity score (ISS) or new ISS (NISS), can predict who requires admission to ICU [13][14][15][16], these anatomical scoring systems are unable to accurately distinguish between patients who subsequently experience a short or prolonged ICU LOS [17][18][19], with the area under the receiver operating characteristic (AUROC) curve values ranging from 0.448-0.804 [17][18][19]. Thus, new models capable of predicting ICU LOS with greater discriminatory power are needed to aid in the development of targeted treatments during the acute post-injury phase.…”
