Type of usual source of care and access to care

The goal of the study was to evaluate the association between types of usual source of care (USC) and access to care for people of different race/ethnicity and insurance coverage. Individuals reporting a doctor's office or health maintenance organization as a USC achieved the highest level of access. Individuals reporting a hospital emergency department as a USC were more likely to have access barriers and unmet needs. The independent effects of race/ethnicity were no longer significant after controlling for the type of USC and other factors. Insurance was a significant moderating factor on access to care.
