| Abstract |
Postoperative pulmonary complications (PPCs) are one of the most important causes of postoperative morbidity and mortality after abdominal surgery. Although chronic obstructive pulmonary disease (COPD) has been considered a risk factor for PPCs, it remains unclear whether mild-to-moderate COPD is a risk factor. This retrospective cohort study included 387 subjects who underwent abdominal surgery with general anesthesia in a tertiary referral hospital. PPCs included pneumonia, pulmonary edema, pulmonary thromboembolism, atelectasis, and acute exacerbation of COPD. Among the 387 subjects, PPCs developed in 14 (12.0%) of 117 patients with mild-to-moderate COPD and in 13 (15.1%) of 86 control patients. Multiple logistic regression analysis revealed that mild-to-moderate COPD was not a significant risk factor for PPCs (odds ratio [OR] =0.79; 95% confidence interval [CI] =0.31-2.03; P=0.628). However, previous hospitalization for respiratory problems (OR =4.20; 95% CI =1.52-11.59), emergency surgery (OR =3.93; 95% CI =1.75-8.82), increased amount of red blood cell (RBC) transfusion (OR =1.09; 95% CI =1.05-1.14 for one pack increase of RBC transfusion), and laparoscopic surgery (OR =0.41; 95% CI =0.18-0.93) were independent predictors of PPCs. These findings suggested that mild-to-moderate COPD may not be a significant risk factor for PPCs after abdominal surgery. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. 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 10 November 2016.
All research outputs
#16,047,334
of 25,374,647 outputs
Outputs from International Journal of Chronic Obstructive Pulmonary Disease
#1,485
of 2,577 outputs
Outputs of similar age
#186,514
of 317,808 outputs
Outputs of similar age from International Journal of Chronic Obstructive Pulmonary Disease
#57
of 82 outputs
Altmetric has tracked 25,374,647 research outputs across all sources so far. This one is in the 34th percentile – i.e., 34% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,577 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.5. This one is in the 37th percentile – i.e., 37% 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 317,808 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 38th percentile – i.e., 38% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 82 others from the same source and published within six weeks on either side of this one. This one is in the 29th percentile – i.e., 29% of its contemporaries scored the same or lower than it.
