Asthma Patients Often Skip Their Medication
Study
Shows Many Patients Aren't Always Honest With Their Doctors About Taking Medicine

-- Many asthma patients with poorly controlled asthma do not take their medications as prescribed, a new study from the U.K.
suggests.
Researchers found that in about a third of cases, poor compliance with treatment was a major factor in difficult-to-treat
asthma.
"There are a lot of reasons patients don't take their medications as they should," researcher
Jacqueline Gamble of Queen's University of Belfast tells us. "Some of these treatments have side effects that are
not pleasant, especially oral corticosteroids. If patients aren't honest, or feel they can't be honest with their
doctors about this, there is very little way to know."
Worldwide, about 300 million people have asthma, including
23 million in the U.S.
Every day in the U.S., 30,000 people have asthma attacks, 1,000 asthma patients are admitted
to hospitals, and 11 people die of the respiratory disease, according to the Asthma and Allergy Foundation of America.
Poor treatment compliance has long been recognized as a significant issue in the management of asthma, but the scope of
the problem is not well understood because objective measurement is difficult.
In the new study, Gamble and colleagues
from Belfast City Hospital assessed compliance with treatment in 182 consecutive patients attending a clinic specializing
in difficult-to-treat asthma.
Inhaled corticosteroid use was determined by examining initial and refill prescriptions.
Researchers used blood tests to assess oral steroid compliance.
Among patients prescribed a maintenance course of
oral steroid, the blood analysis showed that nearly half (45%) were not taking their medication as prescribed. And more than
half of these patients (65%) were also noncompliant with their inhaled treatment.
All of the poorly compliant patients
had initially denied taking less of their medications than they were prescribed.
Women were more likely than men to
be poorly compliant, and patients who scored lower on quality-of-life assessments were also less likely to take their medications
as directed.
Many Reasons for Poor Compliance
"Our experience suggests that not all patients have the
same reasons for poor adherence, and therefore a one-size-fits-all intervention is unlikely to be appropriate," the researchers
write in the November issue of the American Journal of Respiratory and Critical Care Medicine.
American Thoracic
Society past president John E. Heffner, MD, agrees there are many reasons why people with asthma fail to take their medications
as prescribed.
"In cases where noncompliance is unintentional, poor communication is often a big part of the
problem," he tells us. "Physicians may not communicate instructions appropriately or give written instructions that
can be easily followed."
Patients may also intentionally fail to take their medications because they are bothered
by side effects or underestimate the seriousness of their disease.
He says patients need to educate themselves about
their asthma and doctors need to understand that different patients may benefit from different approaches to treatment.
Heffner, a professor of medicine at Providence Portland Medical Center, says, "Physicians need to tailor therapy
in a manner that meets the individual medical, psychological, and social needs of the patient so that the patient has the
greatest opportunity to be compliant."
