Study Population. Individuals who receive the survey will be the primary care provider identified by study participants enrolled in our ongoing study entitled, "Asthma in the Delta Region of Arkansas: Characterization of Disease and Impact of Environmental Factors" (ARIA#53054). We will send the survey to all identified practitioners in Lee, Phillips, Desha, Chicot, St. Francis, and surrounding counties. Future studies will include primary care providers from other Arkansas Delta counties pending funding.
