Healthcare access refers to the ability of individuals to obtain and use healthcare services when needed. This research area focuses on understanding the barriers and facilitators to accessing healthcare, such as geographic location, insurance coverage, affordability, cultural factors, and socio-economic status. Researchers in this field aim to identify disparities in healthcare access and develop interventions to improve access for vulnerable populations, ultimately improving overall health outcomes and reducing health inequalities. This research area is crucial for informing policy and decision-making to ensure that all individuals have equitable access to quality healthcare services.
