Our primary objective was to examine anesthesia work area reservoir isolation of Klebsiella, Acinetobacter, Pseudomonas, and Enterobacter spp (KAPE) pathogens. This is a retrospective analysis of a randomized, prospective, and observational study involving 3 academic medical centers.
Patients included adults undergoing general anesthesia. Gram-negative isolates (N = 2,682) were collected from anesthesia work area reservoirs in 274 randomly selected operating room case pairs. Nine hundred and forty-five isolates were included in this study. Chi square tests were used to examine the association of anesthesia work area reservoirs with KAPE genera isolation.
Acinetobacter pathogens were more likely to be isolated from anesthesia provider hands (risk ratio [RR], 1.07; 95% confidence interval [CI], 1.04-1.10; corrected P = .004) and less likely to be isolated from patients (RR, 0.2; 95% CI, 0.08-0.50; corrected P < .0001). Enterobacter pathogens were more likely to be isolated from patients (RR, 3.34; 95% CI, 1.92-5.81; corrected P = 0.001) and less likely to be isolated from provider hands (RR, 0.89; 95% CI, 0.83-0.97; corrected P = .007).
Anesthesia provider hands are important reservoirs for Acinetobacter spp, whereas patient skin surfaces are key reservoirs for Enterobacter spp. Future work should examine the impact of a multimodal program in controlling the intraoperative spread of Acinetobacter and Enterobacter pathogens.
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 February 2018.
All research outputs
#20,663,600
of 25,382,440 outputs
Outputs from American Journal of Infection Control
#3,725
of 4,282 outputs
Outputs of similar age
#347,762
of 454,408 outputs
Outputs of similar age from American Journal of Infection Control
#49
of 59 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one is in the 10th percentile – i.e., 10% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,282 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 21.4. This one is in the 5th percentile – i.e., 5% 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 454,408 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 13th percentile – i.e., 13% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 59 others from the same source and published within six weeks on either side of this one. This one is in the 8th percentile – i.e., 8% of its contemporaries scored the same or lower than it.
