Multivariate logistic regression analysis for mortality with RIFLE as the AKI variable in the subgroup with ≥20% burn injury

VariableOdds Ratio for Hospital Mortality (95% CI)aP Value
Age (yr)1.11 (1.03–1.20)0.006
ARDS or ALI5.45 (1.45–20.49)0.01
Percentage TBSA1.07 (1.04–1.11)<0.001

  • CI, confidence interval; ARDS, acute respiratory distress syndrome; ALI, acute lung injury, TBSA, total body surface area burned.

  • a Odds ratios for age and percentage TBSA reflect per-year increase in age and per 1% increase in percentage TBSA, respectively.

  • b Compared with no AKI by RIFLE (Risk-Injury-Failure-Loss-End Stage) criteria.
