The CHOICE survey: high rates of persistent and uncontrolled asthma in the United States.

ABSTRACT

BACKGROUND: Surveys have consistently shown that many patients with asthma do not have their disease well controlled. OBJECTIVES: The CHOICE (Comprehensive Survey of Healthcare Professionals and Asthma Patients Offering Insight on Current Treatment Gaps and Emerging Device Options) survey was designed to evaluate the current status of inhalation devices used in asthma treatment, but questions also were included about asthma severity and control. METHODS: A total of 1,000 patients with asthma were interviewed about their use of inhalation devices and asthma-related burden, medication use, and hospital/emergency care. Based on the responses to these questions, asthma severity and control were categorized using methods established in the Expert Panel Report III (EPR 3). RESULTS: Almost half (490) of the patients with asthma participating in the CHOICE survey were not using controller medications. Most of those not using controllers (79%) had persistent asthma; 47% had either mild or moderate persistent asthma. Of those on controllers (510), only 14.3% were well controlled. Acute care utilization was greater for patients with persistent asthma than those with intermittent asthma and for patients with not well and poorly controlled asthma than those with well-controlled asthma. CONCLUSION: The CHOICE survey is particularly pertinent clinically, because it demonstrates for the first time, using EPR 3 methods, the current extent of poor asthma control in the United States. This situation falls far short of national asthma management targets.
