We sought to describe the characteristics of adult bronchiectasis patients enrolled in the United States Bronchiectasis Research Registry (BRR).
The BRR is a database of non-cystic fibrosis bronchiectasis (NCFB) patients enrolled at 13 sites within the United States. Baseline demographic, spirometric, imaging, microbiologic, and therapeutic data were entered into a central web-based database. Patients were subsequently analyzed by the presence NTM.
We enrolled 1826 patients between 2008 and 2014. Patients were predominantly female (79%), white (89%), and never smokers (60%) with a mean age 64±14 years. Sixty-three percent of the patients had a history of NTM disease or NTM isolated at baseline evaluation into the BRR. NTM patients were older, predominantly female, and had bronchiectasis diagnosed at a later age than those without NTM. Gastroesophageal reflux (GERD) was more common in those with NTM whereas asthma, primary immunodeficiency and primary ciliary dyskinesia were more common in those without NTM. Fifty-one percent of patients had spirometric evidence of airflow obstruction. NTM patients were more likely to have diffusely dilated airways and tree-in-bud abnormalities. Pseudomonas and Staphylococcus aureus isolates were less commonly cultured among patients with NTM. Bronchial hygiene measures were used more often in those with NTM; whereas antibiotics used for exacerbations, rotating oral antibiotics, steroid use, and inhaled bronchodilators were more commonly used in those without NTM.
Adult bronchiectasis patients enrolled in the US BRR are described with differences noted in demographic, radiographic, microbiologic, and treatment variables based on stratification of the presence of NTM.

Attention Score in Context
Attention Score in Context
This research output has an Altmetric Attention Score of 22. 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 21 July 2026.
All research outputs
#2,184,992
of 34,492,055 outputs
Outputs from CHEST
#2,011
of 18,144 outputs
Outputs of similar age
#31,830
of 452,020 outputs
Outputs of similar age from CHEST
#26
of 124 outputs
Altmetric has tracked 34,492,055 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 93rd percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 18,144 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 13.1. This one has done well, scoring higher than 89% 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 452,020 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 92% of its contemporaries.
We're also able to compare this research output to 124 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 79% of its contemporaries.
