The purpose of this Request for Applications (RFA) is to establish contracts through competitive applications with entities experienced in Population Health Improvement initiatives targeted for Critical Access Hospitals (CAHs) and Provider-Based Rural Health Clinics (RHCs). The CAH Population Health Improvement Program Area is an optional Flex Program area, which focuses on building capacity of CAHs to achieve measurable improvement in the health outcomes of their communities, with consideration of determinants of health, such as medical care systems and social and physical environments. Critical Access Hospitals are engaged in a broad variety of population health initiatives ranging from enhanced clinical care management tied to accountable care organizations (ACOs) and other value-based purchasing initiatives, to community-based interventions to improve health and address social and community factors that influence health status. This Request for Application is seeking a qualified subject matter expert to support Critical Access Hospitals and their counties to address food insecurity and food-related health disparities in their region, by means of integrating evidence-based nutritional interventions into healthcare systems, emphasizing the prevention and management of diet-related chronic diseases.
