Comparison of the New Injury Severity Score and the Injury Severity Score

Abstract

The NISS should not replace the ISS, as they share similar accuracy and calibration.

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%).…”

The Natural Logarithm Transforms the Abbreviated Injury Scale That Improves Accuracy Scoring

“…Most of the studies have observed better discrimination and calibration for the NISS, [6][7][8][9] and some studies have observed better calibration but equivalent discrimination. [10,11] In addition, a few studies have noted no advantage of the NISS. [12,13] The ISS/NISS have an idiosyncrasy that impairs their predictive power.…”
