Limitations of the TRISS method for interhospital comparisons : a multihospital study
CAYTEN C
J TRAUMA , 1991, vol. 31, n° 4, p. 471-481 Doc n°: 53696 Localisation : Documentation IRR Descripteurs : DA4 - TRAUMATISMES - APPAREIL LOCOMOTEUR The value of the TRISS method for interhospital comparisons of trauma care was studied using data for 5,616 consecutive patients from three trauma centers and five community hospitals. Z-scores were used to compare mortality rates. Three limitations of the methods were : 1) the lack of homogeneity within the patient subcategory of penetrating injuries, specifically between patients with gunshot versus stab wounds; 2) the inability of the TRISS method to predict the survival rate of patients suffering low falls ; and 3) the inability of the TRISS method to account for multiple severe injuries to a single body part.
