The objective of the SDG SCSI Working Group is to investigate means of better provision in primary healthcare and welfare services, increasing the resilience of health systems. Springfield is providing evidence, support and guidance to the working group. Tasks include identifying and disseminate workable, good practice solutions to design and develop a set of evidence informed guidelines to support scalable and sustainable change in national health and welfare systems, researching, testing and providing solutions that address the structural constraints to scaling innovation in national health and welfare systems. The outcomes from Springfield's work will be the reduction of SCSI and understanding of solutions that lead to increased systemic and econystem efficiencies, effectiveness and impact.
