| Abstract |
Staphylococcus aureus and Pseudomonas aeruginosa are major causes of pneumonia in intensive care unit (ICU) patients. Limited data exist regarding the health economic impact of S. aureus and P. aeruginosa pneumonias in the ICU setting. We conducted a retrospective observational cohort study using a 29.6 million enrollee US medical and pharmacy administrative claims database. ICU patients with S. aureus or P. aeruginosa infection per International Classification of Diseases, 9th ed. coding between 01/01/2007-8/31/2012 were compared with ICU patients without any pneumonia or infections of interest. Primary outcomes were costs in 2012 US dollars, healthcare utilization and all-cause mortality associated with hospital-acquired S. aureus or P. aeruginosa pneumonia, and the relative odds of incurring higher costs due to a comorbid condition. Patients with S. aureus or P. aeruginosa pneumonia had longer mean hospital (37.9 or 55.4 vs 7.2 days, P < .001) and ICU stays (6.9 or 14.8 vs 1.1 days, P < .001), a higher rate of mechanical ventilation (62.6 % or 62.3 % vs 7.4 %, P < .001), higher mortality (16.0 % or 20.2 % vs 3.1 %, P < .001), and higher total mean hospitalization costs ($146,978 or $213,104 vs $33,851, P < .001) vs controls. Pneumonia survivors had significantly increased risk of rehospitalization within 30 days (27.2 % or 31.1 % vs 15.3 %, P < .001). Comorbid conditions were not associated with increased cost in the pneumonia cohorts. Healthcare costs and resource utilization were high among ICU patients with S. aureus or P. aeruginosa pneumonia. Reducing the incidence of these infections could lead to substantial cost savings in the United States. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. 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 22 June 2015.
All research outputs
#13,481,146
of 23,730,866 outputs
Outputs from BMC Health Services Research
#4,473
of 7,932 outputs
Outputs of similar age
#119,122
of 265,449 outputs
Outputs of similar age from BMC Health Services Research
#59
of 98 outputs
Altmetric has tracked 23,730,866 research outputs across all sources so far. This one is in the 42nd percentile – i.e., 42% of other outputs scored the same or lower than it.
So far Altmetric has tracked 7,932 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.0. This one is in the 42nd percentile – i.e., 42% 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 265,449 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 54% of its contemporaries.
We're also able to compare this research output to 98 others from the same source and published within six weeks on either side of this one. This one is in the 40th percentile – i.e., 40% of its contemporaries scored the same or lower than it.
