Injury Severity Score (I.S.S) versus New Injury SSeverity (N.I.S.S) at a level one Trauma Unit in South Africa. Are we (Maximal Injury Severity Score) the point?

Anjana Bairagi, David JJ Muckart


The ISS and NISS will be calculated for all patients admitted to a Level I Trauma Unit according to international norms using the Abbreviated Injury Score (AIS) 90 handbook. The predictive value of the scores in relation to mortality will then be compared. In addition a Maximal Injury Severity Score (MISS), a system which has never been evaluated, will be calculated and compared to the ISS and NISS.
