Abstract

The aim of this study was to explore the prognostic impact of clinical factors on the short-term outcomes of renal function (RF) in very elderly patients with acute kidney injury (AKI). We carried out a retrospective cohort study of only very elderly patients who developed AKI at the geriatric department of a tertiary medical center during the period 2007-2015. All patients with AKI were followed up for 90 days after AKI diagnosis or until death. Survivors were divided into recovery and nonrecovery groups according to their RF 90 days post-AKI. RF recovery was defined as an estimated glomerular filtration rate (eGFR) of ≥60 mL/min/1.73 m(2). In total, 668 patients (39.0%) developed AKI, and 652 patients were included in the final analysis. The median age of this population was 87 years, with 95.6% being male. The 90-day mortality rate was 33.6%. Of the 433 survivors, 316 (73.0%) recovered to their baseline eGFR. Body mass index (BMI), baseline eGFR, low mean aortic pressure (MAP), low prealbumin level, hypoalbuminemia, oliguria, blood urea nitrogen (BUN) level, and more severe AKI stage were independent risk factors associated with nonrenal recovery or death. AKI etiology, evaluated by peak serum creatinine (SCr) level and the requirement for dialysis, was not associated with nonrenal recovery. Risk factors for the poor outcomes of RF in very elderly patients with AKI were BMI, baseline eGFR, low MAP, low prealbumin level, hypoalbuminemia, oliguria, BUN level, and more severe AKI stage. Identifying risk factors may help to improve patient outcomes.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 26 January 2017.
All research outputs
#6,833,996
of 8,968,121 outputs
Outputs from Clinical Interventions in Aging
#866
of 1,075 outputs
Outputs of similar age
#220,187
of 308,692 outputs
Outputs of similar age from Clinical Interventions in Aging
#35
of 39 outputs
Altmetric has tracked 8,968,121 research outputs across all sources so far. This one is in the 13th percentile – i.e., 13% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,075 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.3. This one is in the 7th percentile – i.e., 7% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 308,692 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 17th percentile – i.e., 17% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 39 others from the same source and published within six weeks on either side of this one. This one is in the 7th percentile – i.e., 7% of its contemporaries scored the same or lower than it.
