| Abstract |
Patients with chronic obstructive pulmonary disease (COPD) exhibit poor sleep quality and consider morning as the worst time of day for their symptoms. While work has been done to characterize nighttime (NT) and early morning (EM) symptoms in various populations, the impact and factors associated with NT/EM symptoms among patients with COPD in the United States is not well understood. Commercially insured patients aged ≥40 years with one or more medical claim for COPD and one or more pharmacy claim for COPD maintenance medication were identified from the HealthCore Integrated Research Database between September 1, 2010 and August 31, 2011. Consenting respondents were asked whether they had COPD symptoms on at least three nights or at least three mornings during the past week. Respondents were then either assigned to one of three symptom groups to complete the survey or excluded if their predefined group quota limit had been met. Survey completers completed the survey with questions about COPD symptoms and other commonly used patient-reported outcome measures. Respondents with NT/EM symptoms were asked about the frequency, severity, and impact of the symptoms on sleep, morning activities, and anxiety levels. Among respondents with symptoms, 73.1% of respondents with NT symptoms (N=376) and 83% of respondents with EM symptoms (N=506) experienced at least three distinct types of symptoms over the past week, with cough being the most frequently reported symptom. Approximately half of respondents with NT or EM symptoms perceived their symptoms as moderate to very severe, with a majority reporting their symptoms affected their NT sleep and morning activities, and more than half felt anxious due to their symptoms. Multinomial logistic regression showed COPD patients with both or either NT/EM symptoms were associated with poorer health status compared to those without. Improved disease management may reduce NT/EM symptoms and improve health status in patients with COPD. |

Attention Score in Context
This research output has an Altmetric Attention Score of 11. 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 September 2021.
All research outputs
#3,322,320
of 25,371,288 outputs
Outputs from International Journal of Chronic Obstructive Pulmonary Disease
#397
of 2,577 outputs
Outputs of similar age
#40,051
of 270,992 outputs
Outputs of similar age from International Journal of Chronic Obstructive Pulmonary Disease
#2
of 30 outputs
Altmetric has tracked 25,371,288 research outputs across all sources so far. Compared to these this one has done well and is in the 86th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
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 has done well, scoring higher than 84% of its peers.
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 270,992 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 85% of its contemporaries.
We're also able to compare this research output to 30 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 93% of its contemporaries.
