Risk factors for the absence of renal recovery in survivors from developed and emerging countries at hospital discharge (n=581)

Renal recovery criteriaOR (95% CI)
Emerging country2.91 (1.76 to 4.80)
APACHE III scorea1.01 (1.00 to 1.02)
 In developed countries1.01 (0.99 to 1.03)
 In emerging countries1.02 (1.00 to 1.04)b
AKI stage 3 with RRT2.69 (1.53 to 4.72)
Mechanical ventilationa0.56 (0.33 to 0.97)
 In developed countries0.42 (0.18 to 0.98)
 In emerging countries0.64 (0.31 to 1.35)
  • Variables included in the multivariate model were developing or emerging country, coronary artery disease, surgery status, Acute Physiology and Chronic Health Evaluation (APACHE) III score, use of vasopressors, mechanical ventilation, starches, RRT, and significant interaction terms (between country type and mechanical ventilation, between country type and APACHE III). Area under the receiver-operating characteristic curve (c statistic): 0.75 (95% confidence interval, 0.71 to 0.80). Hosmer–Lemeshow: 0.98. OR, odds ratio; 95% CI, 95% confidence interval.

  • a APACHE III score and mechanical ventilation presented significant interactions with the developed/emerging status.
