ABSTRACT

Objective. To determine the discriminative capacity an cost of seven severity systems (TISS, APACHE II, APACHE III, SAPS I and SAPS II) and Mortality Probability Model (MPM II).
Design. Cohort study.
Setting. ICU of a private hospital of Mexico City.
Interventions. Statistical analysis at admission and after 24 hours.
Measurements and main results. The systems with greater discriminatory capacity in descending order were: APACHE III (85.9 ± 2.7%), SAPS II (85.6 ± 2.7%), APACHE II (83.4 ± 2.8%) and MPM II (81.5 ± 3.7%). The most expensive systems were in decreasing order: APACHE III 64.6, SAPS II 59.8, SAPS I 55 and APACHE II 54.3 US dollars, respectively.
Conclusion. APACHE II system has the better discriminatory capacity at the lowest cost.
