Evaluation of the relative weight (rw) of diagnosis-related groups (drg) in critically ill patients (cip) with severe sepsis (ss) according to the major diagnostic categories (mdc)

Methods • Type of Study: prospective, analytical, longitudinal, and observational • Period: January 1-2011 / June 30-2014 (42 months) • Setting : Medical/Surgical ICU • Population: 2559 CIPs admitted consecutively to the ICU; sample: 484 CIPs with SS. • Exclusión criteria: CIPs < 16 y., major burn CIPs, incomplete clinical documentation, and voluntary discharge. • DRG AP-DRG 25.0 version (684 DRG are grouped into 25 Major Diagnostic Categories and 1 extra Category). Each DRG can be medical (M) or surgical (S). • MDC: 1 (neurology), 2 (eye), 3 (ear, nose, mouth, throat), 4 (respiratory), 5 (circulatory), 6 (digestive, 7 (hepatobiliary & pancreas), 8 (musculoskeletal & connective), 9 (skin & breast), 10 (endocrine), 11 (urinary tract), 12 (male reproductive), 13 (female reproductive), 14 (pregnancy & childbirth), 15 (newborn), 16: (blood & immunological), 17 (mMyeloproliferative), 18 (infectious), 19 (mental), 20 (alcohol / drug), 21 (Injuries & poison), 22 (burns), 23 (factors influencing health status), 24 (HIV), 25 (PLT), 0 (PreMed, miscellany) • Excluded MDC: 8 DRG with SS • Depending on the focus of sepsis, SS related to MDC ‘0’ (extra Category) are transferred to another MDC. • Statistical analysis: ANOVA, ́F ́ Snedecor. Scheffe’s test post ANOVA to find out which pairs of MDC are significative.
