Researchers have developed a simple and convenient method to identify patients with chronic obstructive pulmonary disease (COPD) who would benefit from currently available therapies.
CAPTURE is a five-item questionnaire that when used in conjunction with peak expiratory flow measurements had a high rate of sensitivity and specificity for identifying these patients, according to a study published in the American Journal of Respiratory and Critical Care Medicine.
The study by Fernando J. Martinez, MD, MS, of Weill Cornell Medical College, and colleagues was a multi-site, case-control study of 346 men and women. They sought to identify patients with undiagnosed severe asymptomatic COPD.
“There are estimates that state that COPD is undiagnosed in between 60% and 98% of cases depending on what part of the world you are in, and patients with undiagnosed COPD tend to have worse quality of life, higher utilization of health care resources and high mortality compared with people without COPD,” Martinez, told Medical Economics. “We targeted patients with severe COPD in this study because that group of patients has a series of therapeutic alternatives which clearly work to improve health status, symptoms, exacerbation rates and maybe even mortality.”
