The type of medical setting in which persons receive health care for asthma differs for those with private health insurance and those without health insurance. Approximately 30% of medical visits for asthma by persons without health insurance occurred in emergency departments,compared with only 6% of visits by those with private insurance. Asthma is a condition considered to be sensitive to effective primary care and, whether controlled, and would result in fewer visits to the emergency department.
