Lack of Knowledge Leads to Poor Asthma Care
Lack of Knowledge Leads to Poor Asthma Care
By Thomas F. Plaut, MD
The major factor causing death and hospitalizations due to asthma in the United States is lack of knowledge. No, I’m not referring to patients’ lack of knowledge; I’m referring to health professionals. If clinicians don’t understand asthma, they won’t be able to teach their patients how to control it.
I make the diagnosis of uncontrolled asthma almost every time I give a talk to health professionals: A respiratory therapist coughs several times during my presentation, a nurse coughs after blowing peak flow during my hands-on demonstration, or a doctor coughs after laughing at a humorous remark.
These coughers simply don’t know that they’re living with uncontrolled asthma that could worsen unexpectedly at any time. Because competent health professionals often don’t use current practice guidelines to manage their own asthma, it’s no surprise that they don’t provide effective care for their patients.
In 1997, the National Heart, Lung, and Blood Institute (NHLBI) published revised Guidelines for the Diagnosis and Management of Asthma to bring primary care physicians up to date. In the main, they codified the practices that many asthma specialists had been using for years. The guidelines describe a clear path for achieving good results in asthma care, including drug treatment, environmental control, monitoring and patient education.
However, the expert panel’s recommendations are ignored more frequently than they are followed. Most physicians I have queried fail to:
- treat patients who have symptoms more than two days a week with a controller medicine
- give specific, patient-related advice on improving the environment coupled with a clear rationale for doing so
- encourage patients with moderate or severe asthma to monitor their airflow and keep a diary
- give their patients written treatment plans and an asthma booklet that is current, comprehensive and accurate.
It’s clear that these techniques produce excellent outcomes. The year prior to the NHLBI report, I guided interventions covering all 113,000 enrollees under age 15 in two HMOs in Oregon and California. They stressed use of preventive anti-inflammatory medicines, proper delivery of inhaled medicines, peak flow monitoring and patient education. Hospital days for asthma dropped to 36 percent of the national rate. Simultaneously, hospital days for bronchitis, bronchiolitis and pneumonia fell to less than 25 percent of the national rate.
Why don’t all physicians take these simple steps that the guidelines outline to improve asthma care? I’ll answer from my own experience as a pediatrician.
I started treating children with asthma in the Bellevue Hospital emergency room in 1959. When I saw a child with marked retractions, wheezing loudly and breathing rapidly, I gave an injection of adrenaline. Ten minutes after receiving the shot the child was often greatly improved, smiling and breathing easily. The mother, who had been gravely concerned about her child’s health, was grateful. I was pleased to have achieved such dramatic results.
Most pediatricians have cared for hundreds of children with asthma. They’re as impressed with their ability to bring an attack under control rapidly as I was 40 years ago. However, there is much more to asthma care than treating emergencies. In fact, emergencies should rarely occur.
Many doctors are not aware that almost all patients with persistent asthma who use inhaled steroids daily will be able to prevent most attacks. The few that do occur will be less severe.
In addition, health care professionals often don’t realize their patients suffer from symptoms that limit their activities. They get only a brief “snapshot” of a patient in the office. Only a few use a comprehensive diary that would give them a continuing daily account, a “videotape,” of the patient’s status. In the absence of such a record they can’t understand that the patient’s asthma is not adequately controlled.
Asthma causes 500,000 hospitalizations and 5,000 deaths a year in the United States. These numbers will drop when health professionals understand the basics of asthma, its monitoring and treatment; expect their patients to achieve excellent control; and teach them how to manage most asthma problems at home.
In the meantime, patients will settle for poor control unless they know they have an option. Consider three patients’ experiences:
For the three years before we met he had symptoms every afternoon and evening in spite of taking epinephrine, theophylline, cromolyn, metaproteronol and albuterol several times each day and prednisone 5 mg to 30 mg almost daily. His allergist had labeled him as noncompliant.
At his first visit, I learned that he had daily contact with major triggers and that his inhaler technique was seriously flawed. We corrected these problems, and two weeks later his peak flow doubled and his symptoms disappeared.
She said her son had been coughing every few minutes, day and night, since his first month of life. Over the next six months two pediatricians, an allergist, a pulmonologist and an ER doctor treated him, but his symptoms continued.
I recommended specific changes in the environment, cleared his airways with a burst of prednisone, gave him an effective nebulizer cup to deliver cromolyn and simplified his medication routine. Two weeks after his first visit, his symptoms were gone.
She lived with a cat, even though she knew she was allergic to cat dander. I pointed out that even five minutes of contact with a cat can cause inflammation of the airways that may increase her reaction to triggers for 12 weeks. I reviewed inhaler technique with her and increased her dose of inhaled steroid.
When I saw her four weeks later, she was asymptomatic but was still struggling with how to handle the cat, which was a beloved member of her family. I convinced her that her high dose of inhaled steroid would increase her risk of developing osteoporosis. A month later she placed the cat with a friend and was looking forward to reducing her dose of inhaled steroids.
These stories show that patients will seek help and will follow advice that they have reason to trust.

Reasons Why Physicians and Patients Settle for Poor Asthma Control
Many doctors don’t know or don’t believe that:
