Chronic Obstructive Pulmonary
Disease Research, the Top 20 Institutions
This month, ScienceWatch.com presents a
listing of the top 20 institutions which, according to our
Special Topic on
Chronic Obstructive Pulmonary Disease (COPD), attracted
the highest total citations to their papers published on
the topic in
These institutions are the top 20 ranked by total cites out of a pool of
9,945 institutions publishing on this topic, based on the string search
"chronic obstructive pulmonary*" OR "COPD" OR "emphysema*" OR "chronic
obstructive bronchitis*" OR "chronic obstructive airway*" OR "chronic
obstructive lung*" in titles, abstracts, and keywords of original articles,
reviews, and proceedings papers published between January 1, 1999 and
October 31, 2009.
The resulting list of institutions includes 11 US-based universities and
hospitals, as well as three from Canada, and five from Europe. There is
also one multinational pharmaceutical company.
The clear leader of the pack is the University of London Imperial College
of Science, Technology & Medicine, with 357 papers cited a total of
10,598 times. Imperial can also boast of having the top author from our
analysis: Peter Barnes, who ranks at #1 by total cites and by total papers,
based on 135 papers cited 6,153 times. In August of last year, Professor
talked with ScienceWatch.com about one his highly cited review
Harvard University ranks at #2, with 341 papers cited a total of 8,013
times. Genetic factors in lung disease, the role of particulate air
pollution in COPD, and the quality of life in COPD patients are just a few
of the topics studied at Harvard. Edwin Silverman, of Harvard's Channing
Laboratory, is among the top 20 scientists by total number of papers.
Ranking at #3 is the University of British Columbia, with 244 papers cited
a total of 5,608 times. Imagery of the lung is a big topic at this
institution, and the work of James Hogg and Peter Paré, both Lead
Investigators at the university's iCapture Centre, as well as Investigator
Don Sin, is recognized on the top 20 scientists list as well.
Coming in at #4 is Johns Hopkins University, with 223 papers cited a total
of 5,256 times. Among the highly cited topics here are papers on
lung-volume-reduction surgery, guidelines for the treatment of comorbid
diseases, and predictors for mortality in COPD and emphysema.
The fifth-ranked institution is the University of California, Los Angeles,
with 223 papers cited 4,311 times. Clinical trials, particularly with
tiotropium, dominate the most-cited papers from UCLA.
The #6 slot belongs to the University of Pittsburgh, with 167 papers cited
a total of 3,859 times. Steven Shapiro, who ranks at #11 on our list of the
most-cited scientists, hails from this institution.
Washington University in St. Louis places at #7, with 146 papers cited
3,545 times. Matrix metalloproteinases and their role in lung diseases
appear frequently on Washington University's list of most-cited papers; in
fact, three of their top five papers deal with this topic.
The University of Maastricht in the Netherlands is #8, with 212 papers
cited 3,528 times. Issues of inflammation, chronic tissue wasting,
mortality, and the role of diet in COPD are among some of the highly cited
topics under investigation at this university. Two of Maastricht's
researchers, Emiel Wouters and Annemie Schols, are among the most-cited
scientists in our analysis.
Placing at #9 is Tufts University, with 114 papers cited a total of 3,450
times. Ventilation and lung function in patients is a big focus at
Tufts—more than half of the institution's top 20 papers deal with
this topic in some way.
Rounding out the top 10 is the University of California, San Francisco,
with 145 papers cited 3,411 times. UCSF's papers on the topic range from
the molecular level to the human scale: papers on TGF-beta and IL-13 march
side-by-side with papers on population health data, occupational burden of
COPD, and comprehensive care.
The remaining US institutions on the list include the Harvard-affiliated
hospital Brigham & Women's Hospital (#12), the University of Colorado
(#14), the University of Washington (#18), and the Mayo Clinic & Mayo
Foundation (#19). Canada has two more institutions on the list: the
University of Toronto (#11) and McGill University (#16). Royal Brompton
Hospital, which is affiliated with the University of London Imperial
College of Science, Technology, & Medicine, ranks at #17. Two more
Dutch institutions are included: the University of Groningen (#15) and
Leiden University (#20). Multinational pharmaceutical company Boehringer
Ingelheim ranks at #13 on the list.
