This Special Projects of National Significance (SPNS) initiative,System-level Workforce Capacity Building for Integrating HIV Primary Care in Community Health Care Settings, is a multi-site demonstration and evaluation of system-level changes in staffing structures to improve health outcomes along the HIV Care Continuum.  This initiative is funding fifteen (15) demonstration sites for four years to promote the design, implementation, and evaluation of innovative strategies to increase organizations’ workforce capacities and achieve efficient and sustainable service delivery practices that both optimize human resources and improve quality outcomes.  The University of California at San Francisco is serving as the Evaluation and Technical Assistance Center (ETAC) for this initiative. The ETAC will coordinate the multi-site evaluation; provide programmatic technical assistance to the demonstration sites; and lead publication and dissemination efforts of best practices and lessons learned.
