| Abstract |
Infections are a common medical complication in hemorrhagic stroke patients, with vancomycin commonly used as empiric therapy. The purpose of this study was to evaluate the pharmacokinetic parameters of vancomycin in hemorrhagic stroke patients. This was a retrospective study of adult patients with aneurysmal subarachnoid hemorrhage (aSAH) or intracerebral hemorrhage (ICH) admitted between May 2010 and February 2015 who received vancomycin. Predicted pharmacokinetic parameters based on population data were compared with calculated pharmacokinetic parameters based on serum trough concentrations. Eighty aSAH patients and 66 ICH patients met inclusion criteria. In the aSAH group, the mean dosing regimen was 17.6 ± 4 mg/kg every 12 (8-12) h. The mean measured trough concentration was lower than the predicted trough concentration (9.9 ± 4.1 vs. 19 ± 8.7 μg/mL; p < 0.001). The mean calculated elimination rate constant was higher than the predicted value (0.135 ± 0.04 vs. 0.092 ± 0.03 h(-1); p < 0.001), and the mean calculated half-life was lower than predicted (5.7 ± 1.8 vs. 8.3 ± 2.9 h; p < 0.001). In the ICH group, the mean dosing regimen was 15.9 ± 4.3 mg/kg every 12 (8-12) h. Similarly, the mean measured trough concentration was lower than the predicted trough concentration (10.7 ± 4.6 vs. 17.5 ± 8.5 μg/mL; p < 0.001). The mean calculated elimination rate constant was higher than the predicted value (0.106 ± 0.03 vs. 0.079 ± 0.02 h(-1); p < 0.001), and the mean calculated half-life was lower than predicted (7.2 ± 2.3 vs. 9.6 ± 3.2 h; p < 0.001). Patients with hemorrhagic stroke exhibited pharmacokinetic alterations favoring increased elimination of vancomycin when compared to predicted pharmacokinetic parameters based on population data. This may result in underexposure to vancomycin, leading to treatment failure and other medical complications. |

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 06 March 2016.
All research outputs
#20,313,158
of 22,854,458 outputs
Outputs from Neurocritical Care
#1,392
of 1,494 outputs
Outputs of similar age
#252,357
of 298,940 outputs
Outputs of similar age from Neurocritical Care
#20
of 24 outputs
Altmetric has tracked 22,854,458 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,494 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.4. This one is in the 1st percentile – i.e., 1% 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 298,940 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 24 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
