Pediatric asthma is not well controlled in SC and it's important to understand the facilitators and barriers to asthma care, especially in rural and underserved populations. Though school-based clinics provide quality asthma care to pediatric patients and has been shown to increase asthma control and decreased unnecessary health care utilization (i.e., emergency room), enrollment continues to be low. To identify and understand the facilitators and barriers to asthma care within school-based clinics, it is important to query caregivers (parents, grandparents, foster parents, legal guardians) and providers (doctors, APPs) to elicit their thoughts and opinions. This study will include caregiver and provider surveys and individual interviews to collect and analyze these thoughts and opinions.
