As one of the most common chronic diseases in the United States, asthma affects more than 20 million Americans. Although many advances have been made in asthma care, the disease remains a growing public health concern.

A 55-year-old woman who had been admitted to the hospital the previous night was still short of breath when Chris Garvey, MSN, FNP, MPA, entered her room at Seton Medical Center in Daly City, Calif.

Because it was the woman’s first bout of asthma, Garvey explained how certain genetic and environmental factors can trigger asthma, and how patients can become allergic to animal dander, pollen, and other particles in the air.

After explaining how to use the appropriate medications, Garvey suggested they meet with the woman’s primary care physician to devise a long-term asthma management plan.

Garvey is one of many nurses who work with adult asthma patients. As one of the most common chronic diseases in the United States, asthma affects more than 20 million Americans. Although many advances have been made in asthma care, the disease remains a growing public health concern.

According to the national Centers for Disease Control and Prevention, asthma accounts for more than 10 million outpatient clinic visits, and nearly 2 million emergency department visits each year in the United States.

Garvey, who has worked in asthma care for the past 27 years, and is a volunteer with the American Lung Association, also can empathize with the fears and concerns of her patients. Four years ago, she was diagnosed with asthma and chronic bronchitis.

“Patients know I’m speaking from experience,” Garvey said. “I’m a former smoker, so when I tell them smoking exacerbates their asthma symptoms, they take me seriously.”

Two major types of oral and inhaled treatments are used to control asthma symptoms: long-acting medications that prevent and control asthma, and short-acting medications used for relief of asthma symptoms.

Long-acting medications include long-acting bronchodilators and anti-inflammatory drugs such as inhaled corticosteroids that stop or prevent inflammation in the airways. A newer class of asthma medications, called anti-leukotrienes, block leukotriene receptors in the body. This prevents leukotrienes from contributing to inflammation in the airways.

Short-acting inhaled bronchodilators, or inhaled steroids, open the air passages and are generally used as “rescue medications” to stop an asthma attack.

Six years ago, the emergency department at Seton Medical Center was inundated with asthma patients. Realizing that patients weren’t receiving optimal care from their brief ED visits, the hospital instituted a standardized intervention to assist patients in managing their conditions.

“Now, when patients come to the ED, they receive training from a nurse who teaches them to identify triggers, how to use medications, and stresses the importance of following up with their doctor and having an asthma management plan,” Garvey said. “We teach them asthma can’t be cured but it can be controlled, and through this program we’ve seen our return rate in the ED drop from 56% to 1%.”

Uphill battle

Susan Janson, RN, DNSc, ANP, FAAN, a professor of nursing and medicine at the University of California, San Francisco, and a longtime American Lung Association volunteer, has seen a lot of progress in asthma care, yet she’s also watched the condition become more prevalent.

“The inhaled therapies we use today are more effective than the oral therapies we used years ago,” Janson said. “And I’ve seen significant improvements from teaching patients individualized self-management practices.”
