This ISO seeks solution summaries and proposals for projects that fall within the general scope of the ARPA-H Scalable Solutions mission office (SSO). SSO expands what is technically possible by developing approaches that will leverage an interdisciplinary approach and collaborative networks to address challenges of geography, distribution, manufacturing, data and information, thereby improving health care access and affordability. In the United States, many communities and remote areas lack access to timely and quality health care, which leads to disparities in health outcomes for those populations. Bottlenecks during the manufacturing processes of products and health technologies also lead to delays and limited availability, preventing effective distribution of health care solutions to areas of need, especially in emergencies.
