| Abstract |
Research has suggested a significant burden for patients with asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS). However, few studies have studied this population in the People's Republic of China, a region in the midst of rapid epidemiological change with respect to respiratory disease. The aim of this study was to assess the prevalence of ACOS and its association with patient outcomes in urban China. Data from the 2010, 2012, and 2013 China National Health and Wellness Survey, an Internet-based survey of adults in urban China, were used (N=59,935). Respondents were categorized into one of four groups based on self-reported physician diagnoses: ACOS, asthma only, COPD only, or control (ie, no asthma or COPD). A propensity score matching procedure was conducted to cull the control group into a subgroup (ie, matched controls) who resembled patients with ACOS, asthma only, and COPD only. These four groups (ACOS, asthma only, COPD only, matched controls) were then compared with respect to health status (Short Form-12 version 2/Short Form-36 version 2), work productivity, and health care resource use using generalized linear models. Patients with ACOS (N=366) comprised 0.61% of the adult population, 30.73% of the asthma population, and 18.60% of the COPD population in the People's Republic of China. Patients with ACOS reported significantly worse health status (eg, health utilities =0.63, 0.66, 0.63, and 0.69 for ACOS, COPD only, asthma only, and matched controls, respectively) and significantly greater work impairment (eg, overall work impairment =43.65%, 35.19%, 48.55%, and 29.80%, respectively) and health care resource use (eg, physician visits in the past 6 months =5.13, 3.84, 4.65, and 2.39, respectively) compared with matched controls and patients with COPD only. Few significant differences were observed between patients with ACOS and asthma only. Patients with ACOS have a greater comorbidity burden and significantly worse health outcomes compared with COPD only patients and matched controls. Better management of these patients may help to improve their outcomes. |

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 08 August 2017.
All research outputs
#15,738,224
of 25,371,288 outputs
Outputs from International Journal of Chronic Obstructive Pulmonary Disease
#1,421
of 2,577 outputs
Outputs of similar age
#198,141
of 353,651 outputs
Outputs of similar age from International Journal of Chronic Obstructive Pulmonary Disease
#42
of 83 outputs
Altmetric has tracked 25,371,288 research outputs across all sources so far. This one is in the 37th percentile – i.e., 37% 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 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 353,651 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 42nd percentile – i.e., 42% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 83 others from the same source and published within six weeks on either side of this one. This one is in the 45th percentile – i.e., 45% of its contemporaries scored the same or lower than it.
