Access to care is a research area that focuses on the ability of individuals to obtain timely, affordable, and appropriate healthcare services. This includes examining barriers that prevent individuals from accessing care, such as financial constraints, geographic location, and lack of health insurance. Researchers in this area often analyze disparities in access to care based on factors such as race, ethnicity, income, and education level. The goal of research in this area is to identify and address barriers to healthcare access in order to improve health outcomes and reduce healthcare disparities.
