Research Question(s):
- How does the quality of asthma care - including timely diagnosis, assessment, immunization, medication prescription, and access to testing - vary when comparing Latino adults to non-Latino white adults?
- Among adults with asthma, how do Latino adults vary from non-Latino white adults in how they utilize primary asthma care in Community Health Centers?
- How do Latino and non-Latino white adults with asthma vary in how they utilize acute care, including clinic visits, emergency department visits, and inpatient hospitalization?
- Do different subgroups of Latino-Americans, such as Latinos of Mexican, Dominican, or Cuban heritage, utilize asthma care at different rates and receive care of differing quality?
- Relatively, do individual factors (e.g., income, preferred language, insurance coverage, and migrant status) or community-level factors (e.g., community poverty, education, and environmental factors) contribute more to a person's (focusing on Latinos, but including others as well) likelihood of receiving primary asthma care, utilizing acute care, or experiencing asthma-related death?
