| Abstract |
COPD is a common cause for hospital admission. Conventional studies of the epidemiology of COPD involved large patient number and immense resources and were difficult to be repeated. The present study aimed at assessing the utilization of a computerized data management system in the collection and analysis of the epidemiological and clinical data of a large COPD cohort in Hong Kong (HK). It was a computerized, multicenter, retrospective review of the characteristics of patients discharged from medical departments of the 16 participating hospitals with the primary discharge diagnosis of COPD in 1 year (2012). Comparison was made between the different subgroups in the use of medications, ventilatory support, and other health care resources. The mortality of the subjects in different subgroups was traced up to December 31, 2014. The top 10 causes of death were analyzed. In total, 9,776 subjects (82.6% men, mean age = 78 years) were identified. Of the 1,918 subjects with lung function coding, 85 (4.4%), 488 (25.5%), 808 (42.1%), and 537 (28.0%) subjects had the Global Initiative for Chronic Obstructive Lung Disease (GOLD) 1, 2, 3, and 4 classes, respectively. Patients with higher GOLD classes had higher number of hospital admissions, longer hospital stay, increased usage of noninvasive mechanical ventilation (NIV), combinations of long-acting bronchodilators, and higher mortality. Of the 9,776 subjects, 2,278 (23.3%) received NIV, but invasive mechanical ventilation was uncommon (134 of 9,776 subjects [1.4%]); 4,427 (45.3%) subjects had died by the end of 2014. The top causes of death were COPD, pneumonia, lung cancer, and other malignancies. Patients admitted to hospitals for COPD in HK had significant comorbidities, mortality, and imposed heavy burden on health care resources. It is possible to collect and analyze data of a large COPD cohort through a computerized system. Suboptimal coding of lung function results was observed, and underutilization of long-acting bronchodilators was common. |

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 08 July 2018.
All research outputs
#17,292,294
of 25,382,440 outputs
Outputs from International Journal of Chronic Obstructive Pulmonary Disease
#1,732
of 2,578 outputs
Outputs of similar age
#221,357
of 342,877 outputs
Outputs of similar age from International Journal of Chronic Obstructive Pulmonary Disease
#55
of 77 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one is in the 21st percentile – i.e., 21% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,578 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 24th percentile – i.e., 24% 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 342,877 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 26th percentile – i.e., 26% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 77 others from the same source and published within six weeks on either side of this one. This one is in the 22nd percentile – i.e., 22% of its contemporaries scored the same or lower than it.
