In critically ill patients with severe acute kidney injury (AKI), does delaying renal replacement therapy (RRT) improve survival compared to early initiation? This pivotal randomized controlled trial evaluated early versus delayed initiation strategies for RRT in ICU patients with severe AKI. The early-strategy group received RRT within 6 hours of randomization, while the delayed group only initiated RRT if specific criteria, such as persistent oliguria or severe metabolic derangements, were met. The trial enrolled 620 patients across 31 French ICUs. The study found no significant difference in 60-day mortality between the early and delayed groups. However, 49% of patients in the delayed group avoided RRT altogether, with fewer catheter-related bloodstream infections compared to the early group. Recovery of renal function, marked by increased urine output, occurred earlier in the delayed group. These findings suggest that a delayed RRT strategy can safely reduce the need for intervention in critically ill patients without compromising survival, emphasizing the importance of individualized decision-making in AKI management.

摘要

In critically ill patients with severe acute kidney injury (AKI), does delaying renal replacement therapy (RRT) improve survival compared to early initiation? This pivotal randomized controlled trial evaluated early versus delayed initiation strategies for RRT in ICU patients with severe AKI. The early-strategy group received RRT within 6 hours of randomization, while the delayed group only initiated RRT if specific criteria, such as persistent oliguria or severe metabolic derangements, were met. The trial enrolled 620 patients across 31 French ICUs. The study found no significant difference in 60-day mortality between the early and delayed groups. However, 49% of patients in the delayed group avoided RRT altogether, with fewer catheter-related bloodstream infections compared to the early group. Recovery of renal function, marked by increased urine output, occurred earlier in the delayed group. These findings suggest that a delayed RRT strategy can safely reduce the need for intervention in critically ill patients without compromising survival, emphasizing the importance of individualized decision-making in AKI management.
