Lack of communication between patients and health care providers about chronic obstructive pulmonary disease (COPD) remains a major barrier to diagnosis of this disease, according to the results of a Web-based survey released today by the National Heart Lung, and Blood Institute (NHLBI) of the National Institutes of Health. More Americans, particularly smokers, are talking to their doctor or health care provider about the symptoms of COPD, which is an encouraging sign that awareness efforts are taking hold. Patients and providers, though, can still do more.
"A good conversation between patients and providers about COPD can make a
real difference for disease sufferers. It's no secret that early diagnosis
and treatment can improve daily living for those who have COPD - but you
can't get there without an open line of dialogue in the exam room," said
James Kiley, Ph.D., director of the NHLBI Division of Lung Diseases. "That's
why patients and providers need to be aware of COPD, its risk factors and
symptoms, how it affects daily life and what can be done to help get them
back to doing the things they love."
COPD, which in 2010 surpassed stroke to become the third leading cause of
death in the United States, is a serious lung disease which over time makes
it harder to breathe. It affects an estimated 24 million Americans, but as
many as half of those affected remain undiagnosed. This is partially because
symptoms of the disease - such as shortness of breath, chronic coughing or
wheezing, production of excess sputum, or a feeling of being unable to take
a deep breath - come on slowly and worsen over time, leaving many to dismiss
their symptoms and delay seeking diagnosis and treatment until the disease
is advanced.
The survey found a dramatic increase in the numbers of current smokers, a
key COPD risk group, who had discussed their symptoms with their doctors -
from 42 percent in 2009 to 67 percent in 2013. Overall, 26 percent of adults
who reported experiencing these symptoms stated they had not discussed these
symptoms with their doctor or health care provider. Physicians also missed
opportunities; 82 percent of current smokers who reported symptoms had a
conversation with their doctor about their smoking history, but only 37
percent of former smokers, who are also at risk, reported a similar
conversation.
According to the survey, COPD awareness issues contribute to this missed
dialogue. For example, three of the top reasons cited by people with COPD
symptoms who did not talk to a doctor were "I did not think of it," "I've
had these problems for years," and "these problems will just go way in
time." Also, only 18 percent of symptomatic people who discussed their
symptoms heard their provider mention COPD.
"Regardless of positive developments, the challenge remains that more than
1 in 3 Americans do not know what COPD is or how it affects them - and less
than half understand that COPD can be treated," said Kiley. "COPD is the
only major chronic disease where deaths are not decreasing. It is critical
for people to understand whether they may be at risk and recognize their
symptoms as early as possible."
Kiley said the NHLBI will continue to lead in public education and
outreach, primarily through the COPD Learn More Breathe Better campaign.
COPD Learn More Breathe Better, the first national awareness campaign on
COPD, aims to improve knowledge among those with and at risk for the
disease, as well as health care providers - particularly those in a primary
care setting. Now in 50 states and the District of Columbia, the Breathe
Better Network of state and local organizations will be conducting
activities and events throughout November as part of National COPD Awareness
Month. The COPD Learn More Breathe Better campaign also has developed tools
to facilitate discussions between providers and patients in the exam room.
As part of the NHLBI's broader effort to bolster the federal dialogue on
COPD, the institute also recently hosted a workshop attended by
representatives from 22 federal agencies and institutes invested in COPD
research and education, to discuss ways to enhance the federal response to
this serious public health problem. The attendees shared information about
current COPD activities and identified areas where collaboration could
improve disease prevention, ascertainment, diagnosis, and treatment. The
representatives next aim to meet with external, non-federal stakeholders to
discuss ways to respond to the growing COPD burden.
COPD most often occurs in people age 40 and older with a history of
smoking. However, as many as 1 in 6 people with COPD have never smoked. COPD
also can occur in people with a genetic condition known as alpha-1
antitrypsin deficiency or through long-term exposure to substances that can
irritate the lungs, such as dust or fumes.
COPD is diagnosed with a simple test called spirometry, which can be
conducted in a doctor's office. The test involves breathing out as hard and
fast as possible into a tube connected to a machine that measures lung
function.
The NHLBI analyzed the results of the annual HealthStyles survey of public
health attitudes, knowledge, practices, and lifestyle habits among a
nationally-representative sample of U.S. adults, conducted each year by
Porter Novelli, the communications contractor for the NHLBI's COPD Learn
More Breathe Better campaign. The latest survey was conducted in summer
2013; results represent a sample of 4,703 U.S. adults, and have a margin of
error of 1.4 percentage points.
Part of the National Institutes of Health, the National Heart, Lung, and
Blood Institute (NHLBI) plans, conducts, and supports research related to
the causes, prevention, diagnosis, and treatment of heart, blood vessel,
lung, and blood diseases; and sleep disorders. The Institute also
administers national health education campaigns on women and heart disease,
healthy weight for children, and other topics.
