Navajo perceptions of asthma and asthma medications: clinical implications.
BACKGROUND
Despite the large number of asthma patients, relatively little is known about the beliefs of asthmatic children and their parent(s), or the extent to which these beliefs influence management of the disease.


OBJECTIVE
The purpose of this study was to examine how medication-taking and the use of health care services were influenced by perceptions of the disease and beliefs about medications among Navajo families.


METHODS
Ethnographic interviews were used to investigate the disease and medication beliefs of 22 Navajo families with 29 asthmatic children.


RESULTS
Most respondents perceived asthma as the transient experience of symptoms in someone who was chronically vulnerable to breathing problems. The majority (97%) of these asthmatics reported using bronchodilators, although only 34% reported current use of antiinflammatory medications. Although controller medications were distinguished from rescue medications, they were thought to have the same effect on the lungs. Many families were concerned about becoming dependent on the medicines and attempted to "wean" the asthmatic from the drugs. A large proportion (80%) of children had assumed responsibility for their own medication taking. Parents often referred to previous attacks requiring treatment in the emergency department when deciding whether to initiate medication or seek medical attention, often resulting in a delay of treatment. Nebulized treatments delivered in the emergency department were perceived to be the strongest therapy available. As a result, visits to the emergency department were common (79%), as were hospital admissions (57%).


CONCLUSIONS
This study provides evidence that, among pediatric Navajo asthma patients, perceptions of asthma and beliefs about the activity of asthma medications influence when and how often asthma medicines are taken, as well as the use of health care services. In addition, excessive reliance on emergency treatments and the high rates of hospital admissions suggest that asthma is undertreated in this group of Navajo patients.
