This policy paper, produced by the Office for Family Health Education & Research at the UAB School of Medicine, is designed to create primary care rational service areas (PCSA) for Alabama that are both descriptive and normative, based on spatial accessibility and which meet federal criteria for HRSA Rational Service Areas (RSA). In addition, it will establish an Alabama statewide network of federally defined PCSAs that serve as geographic units wherein defined populations of Alabama residents have access to primary care physicians at a functional geographic level (spatial accessibility).
