| Abstract |
The aim of this study was to extend previous findings and determine the value of prompt initiation of maintenance treatment (MT) following COPD exacerbations requiring hospitalization or an emergency department (ED) visit. Administrative claims data (collected between January 1, 2009 and June 30, 2012) from an employer-sponsored commercially insured population were retrospectively used to identify patients with a COPD exacerbation resulting in hospitalization or an ED visit. Patients initiating approved MT for COPD within 30 days of discharge/diagnosis (prompt) were compared with those initiating MT within 31-180 days (delayed). COPD-related total, medical, and prescription drug costs during a 1-year follow-up period were evaluated using semilog ordinary least square regressions, controlling for baseline characteristics plus COPD-related costs from the previous year. The odds and number of subsequent COPD-related exacerbations during the follow-up were compared between the prompt and delayed cohorts using logistic regression and zero-inflated negative binomial models, respectively. A total of 6,521 patients with a COPD-related hospitalization or an ED visit were included, of whom 4,555 received prompt MT and 1,966 received delayed MT. Adjusted COPD-related total and medical costs were significantly lower for the prompt MT than the delayed MT cohorts (US$3,931 vs US$4,857 and US$2,327 vs US$3,087, respectively; both P<0.010), as were COPD-related prescription costs (US$1,526 vs US$1,683, P<0.010) during the 1-year follow-up period. Patients receiving delayed MT were 68% more likely to have a subsequent exacerbation requiring hospitalization and 80% more likely to have an exacerbation requiring an ED visit. Prompt initiation of MT following a COPD-related hospitalization or an ED visit was associated with a significant reduction in COPD-related costs and odds of exacerbation in the following year compared with delayed initiation. |

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 June 2016.
All research outputs
#16,188,873
of 25,584,565 outputs
Outputs from International Journal of Chronic Obstructive Pulmonary Disease
#1,470
of 2,571 outputs
Outputs of similar age
#204,575
of 354,190 outputs
Outputs of similar age from International Journal of Chronic Obstructive Pulmonary Disease
#46
of 83 outputs
Altmetric has tracked 25,584,565 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 2,571 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 38th percentile – i.e., 38% 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 354,190 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 39th percentile – i.e., 39% 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 38th percentile – i.e., 38% of its contemporaries scored the same or lower than it.
