Renal Replacement Therapy in Severe Burns: A Multicenter Observational Study.

ABSTRACT: Acute kidney injury (AKI) after severe burns is historically associated with a high mortality. Over the past two decades, various modes of renal replacement therapy (RRT) have been used in this population. The purpose of this multicenter study was to evaluate demographic, treatment, and outcomes data among severe burn patients treated with RRT collectively at various burn centers around the United States. After institutional review board approval, a multicenter observational study was conducted. All adult patients aged 18 or older, admitted with severe burns who were placed on RRT for acute indications but not randomized into a concurrently enrolling interventional trial, were included. Across eight participating burn centers, 171 subjects were enrolled during a 4-year period. Complete data were available in 170 subjects with a mean age of 51 ± 17, percent total body surface area burn of 38 ± 26% and injury severity score of 27 ± 21. Eighty percent of subjects were male and 34% were diagnosed with smoke inhalation injury. The preferred mode of therapy was continuous venovenous hemofiltration at a mean delivered dose of 37 ± 19 (ml/kg/hour) and a treatment duration of 13 ± 24 days. Overall, in hospital, mortality was 50%. Among survivors, 21% required RRT on discharge from the hospital while 9% continued to require RRT 6 months after discharge. This is the first multicenter cohort of burn patients who underwent RRT reported to date. Overall mortality is comparable to other critically ill populations who undergo RRT. Most patients who survive to discharge eventually recover renal function.

Project description:IntroductionIndications for renal replacement therapy (RRT) have not been generally standardized and vary among intensive care units (ICUs). We aimed to assess the proportion, indications, and modality of RRT, as well as the association between the proportion of RRT use and 90-day mortality in patients with septic shock in Finnish adult ICUs.MethodsWe identified patients with septic shock from the prospective observational multicenter FINNAKI study conducted between 1 September 2011 and 1 February 2012. We divided the ICUs into high-RRT and low-RRT ICUs according to the median of the proportion of RRT-treated patients with septic shock. Differences in indications, and modality of RRT between ICU groups were assessed. Finally, we performed an adjusted logistic regression analysis to evaluate the possible association of the ICU group (high vs. low-RRT) with 90-day mortality.ResultsOf the 726 patients with septic shock, 131 (18.0%, 95% CI 15.2 to 20.9%) were treated with RRT. The proportion of RRT-treated patients varied from 3% up to 36% (median 19%) among ICUs. High-RRT ICUs included nine ICUs (354 patients) and low-RRT ICUs eight ICUs (372 patients). In the high-RRT ICUs patients with septic shock were older (P?=?0.04), had more cardiovascular (P <0.001) and renal failures (P?=?0.003) on the first day in the ICU, were more often mechanically ventilated, and received higher maximum doses of norepinephrine (0.25 ?g/kg/min vs. 0.18 ?g/kg/min, P <0.001) than in the low-RRT ICUs. No significant differences in indications for or modality of RRT existed between the ICU groups. The crude 90-day mortality rate for patients with septic shock was 36.2% (95% CI 31.1 to 41.3%) in the high-RRT ICUs compared to 33.9% (95% CI 29.0 to 38.8%) in the low-RRT ICUs, P?=?0.5. In an adjusted logistic regression analysis the ICU group (high-RRT or low-RRT ICUs) was not associated with 90-day mortality.ConclusionsPatients with septic shock in ICUs with a high proportion of RRT had more severe organ dysfunctions and received more organ-supportive treatments. Importantly, the ICU group (high-RRT or low-RRT group) was not associated with 90-day mortality.

Project description:IntroductionSevere pneumonia is a crucial issue in the development of acute kidney injury (AKI). This study evaluated the efficacy of early goal-directed renal replacement therapy (GDRRT) for the treatment of severe pneumonia-associated AKI.MethodsIn this real-world retrospective cohort study, we recruited 180 patients with severe pneumonia who were hospitalized and received GDRRT in a third-class general hospital in East China between January 1, 2017, and December 31, 2021. Clinical data on baseline characteristics, biochemical indicators, and renal replacement therapy were collected. Patients were divided into Early and Late RRT groups according to fluid status, inflammation progression, and pulmonary radiology. We investigated in-hospital all-cause mortality (primary endpoint) and renal recovery (secondary endpoint) between the two groups.ResultsAmong the 154 recruited patients, 80 and 74 were in the early and late RRT groups, respectively. There were no significant differences in the demographic characteristics between the two groups. The duration of admission to RRT initiation was significantly shorter in Early RRT group [2.5(1.0, 8.7) d vs. 5.0(1.5,13.5) d, p = 0.027]. At RRT initiation, the patients in the Early RRT group displayed a lower percentage of fluid overload, lower doses of vasoactive agents, higher CRP levels, and higher rates of radiographic progression than those in the Late RRT group. The all-cause in-hospital mortality was significantly lower in the Early RRT group than in Late group (52.5% vs. 86.5%, p < 0.001). Patients in the Early RRT group displayed a significantly higher proportion of complete renal recovery at discharge (40.0% vs. 8.1%, p < 0.001).ConclusionThis study clarified that early GDRRT for the treatment of severe pneumonia-associated AKI based on fluid status and inflammation progression, was associated with reduced hospital mortality and better recovery of renal function. Our preliminary study suggests that early initiation of RRT may be an effective approach for severe pneumonia-associated AKI.
