The United States Agency for International Development (USAID) is seeking input through a Request for Information (RFI) for the Integrated Health Systems Strengthening Activity, aimed at enhancing health system resilience and performance globally. This initiative focuses on gathering insights from various stakeholders to inform the planning and design of health system improvements, particularly in the context of post-COVID-19 recovery, with an emphasis on integrated approaches that align with country priorities. The RFI invites responses on topics such as leadership, technical challenges, and local system strengthening, and it is important to note that this is not a funding opportunity but rather an exploratory effort to guide future health system investment strategies. Interested parties should submit their responses electronically to OHS_MarketResearch@usaid.gov by April 11, 2023, and for further inquiries, they can contact Imran Mahmud at 202-567-4646.
