Improving access

Access is defined as the degree of fit between the user and the service; the better the fit, the better the access. Using the theory developed by Penchansky and Thomas, access is optimized by accounting for the different dimensions of access: accessibility; availability; acceptability; affordability; and adequacy in service design, implementation and evaluation. These dimensions are independent yet interconnected and each is important to assess the achievement of access. However, I argue that one dimension is missing – awareness. I propose that awareness is integral to access, that it should become a permanent part of the theory, and be applied whenever using the theory to develop, implement, or evaluate health care services and access more generally.
